RISK/RETURN SUMMARY

Principal Funds, Inc. (“Principal Funds”) offers many investment portfolios, one of which is available through this prospectus. Principal Management Corporation (“Principal”)* serves as the manager for Principal Funds. Through the Management Agreement with Principal Funds, Principal provides investment advisory and certain corporate administrative services to Principal Funds.

Principal Funds Distributor, Inc. (the “Distributor”)* is Principal Funds’ principal underwriter for Class A and Class C shares.

The Sub-Advisors for the Global Diversified Income Fund are Principal Global Investors, LLC*, Principal Real Estate Investors, LLC*, and Spectrum Asset Management, Inc.*

* Principal Management Corporation; Principal Global Investors, LLC; Principal Real Estate Investors, LLC; Principal Funds Distributor, Inc.; and Spectrum Asset Management, Inc. are affiliates of Principal Life Insurance Company and with it are subsidiaries of Principal Financial Group, Inc. and members of the Principal Financial Group.

Class A shares are generally sold with a sales charge that is a variable percentage based on the amount of the purchase. Class C shares are not subject to a sales charge at the time of purchase but are subject to a contingent deferred sales charge (“CDSC”) on shares redeemed within the applicable CDSC period as described in this prospectus. See “Choosing a Share Class” and “CDSC Calculation and Waivers” for more information.

Main Strategies and Risks

The Fund’s investment objective is described in the summary description of the Fund. The Board of Directors may change the Fund’s objective or its investment strategies without a shareholder vote if it determines such a change is in the best interests of the Fund. If there is a material change to the Fund’s investment objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that a Fund will meet its objective.

The summary of the Fund also describes the Fund’s primary investment strategies (including the type or types of securities in which the Fund may invest), any policy of the Fund to concentrate in securities of issuers in a particular industry or group of industries), and the principal risks associated with an investment in the Fund. A fuller discussion of investment strategies and risks appears later in the Prospectus under the caption “Certain Investment Strategies and Related Risks.”

The Fund may invest up to 100% of its assets in cash and cash equivalents for temporary defensive purposes in response to adverse market, economic, or political conditions as more fully described under the caption “Certain Investment Strategies and Related Risks–Temporary Defensive Measures.”

The Fund is designed to be a portion of an investor’s portfolio. The Fund is not intended to be a complete investment program. Investors should consider the risks of the Fund before making an investment and be prepared to bear investment losses during periods of adverse market conditions. The value of your investment in the Fund changes with the value of the investments held by the Fund. Many factors affect that value, and it is possible that you may lose money by investing in the Fund. Factors that may adversely affect the Fund as a whole are called “principal risks.” The principal risks of investing in the Fund are stated as to the Fund in the Fund’s description. The principal risks are more fully explained in Appendix A to this prospectus.

There can be no assurance that any Fund will achieve its investment objective. It is possible to lose money by investing in the Funds. An investment in a Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

GLOBAL DIVERSIFIED INCOME FUND 
 
Sub-Advisor(s):   Principal Global Investors, LLC, ("PGI”), Principal Real Estate Investors, LLC (“Principal-REI"), and   
  Spectrum Asset Management, Inc. ("Spectrum”) 
 
Objective:  The Fund seeks consistent cash income through a diversified, yield-focused investment strategy. 
 
Investor Profile: The Fund may be an appropriate investment for investors seeking high cash returns, who are willing   
  to accept the risk associated with investing in equities and below-investment-grade fixed income 
  securities. 

Main Strategies and Risks

The Fund will invest a majority of its assets in fixed income asset classes, such as high yield bonds, preferred stocks, and emerging market debt securities, to provide incremental yields over a portfolio of government securities. In addition, the Fund will invest in equity securities of global companies principally engaged in the real estate industry and value equities of global companies to provide dividend yields and diversify fixed income-related risks in the Fund. The Fund seeks to provide yield by having each sub-advisor focus on those securities offering the best risk-adjusted yields within their respective asset class.

Approximately 35% of the Fund's assets will be invested in high yield and other income-producing securities including corporate bonds, corporate loan participations and assignments, convertible securities, credit default swaps, and securities of companies in bankruptcy proceedings or otherwise in the process of debt restructuring. The "high yield" securities in which the Fund invests are commonly known as "junk bonds" which are rated Ba or lower by Moody's Investor Service, Inc. ("Moody's") or BB or lower by Standard & Poor's Rating Service ("S&P"). These securities offer a higher yield than other, higher rated securities, but they carry a greater degree of risk and are considered speculative with respect to the issuer's ability to pay interest and to repay principal. It is expected that this portion of the Fund will have a weighted average quality rating of Ba3 as measured by Moody's or BB- by S&P. The average duration will be 2-3 years. PGI will manage this portion of the Fund.

Approximately 20% of the Fund's assets will be invested in equity securities of global companies principally engaged in the real estate industry ("real estate companies"). A real estate company has at least 50% of its assets, income or profits derived from products or services related to the real estate industry. Real estate companies include real estate investment trusts (“REITs”), REIT-like entities, and companies with substantial real estate holdings such as paper, lumber, hotel and entertainment companies as well as building supply manufacturers, mortgage lenders, and mortgage servicing companies. This portion of the Fund may invest in smaller capitalization companies. Principal-REI will manage this portion of the Fund.

Approximately 20% of the Fund's assets will be invested in preferred securities of U.S. companies primarily rated BBB or higher by S&P or Baa by Moody's or, if unrated, of comparable quality in the opinion of the Sub-Advisor. This portion of the Fund focuses primarily on the financial services, REITs, and utility industries. The rest of this portion of the Fund's assets may be invested in common stocks, debt securities, credit default swaps, and securities issued or guaranteed by the U.S. government or its agencies or instrumentalities. Spectrum will manage this portion of the Fund.

Approximately 15% of the Fund's assets will be invested in a diversified portfolio of value equity securities of companies located or operating in developed countries (including the United States) and emerging markets of the world to provide dividend yields. The equity securities will ordinarily be traded on a recognized foreign securities exchange or traded in a foreign over-the-counter market in the country where the issuer is principally based, but may also be traded in other countries including the United States. PGI will manage this portion of the Fund.

Approximately 10% of the Fund's assets will be invested in a diversified portfolio of bond issues issued primarily by governments, their agencies, local authorities and instrumentalities and corporate entities domiciled in or exercising the predominant part of their economic activities in emerging markets in Europe, Latin America, Asia, and the Middle East. The target duration for the portfolio will be 2-3 years. The targeted credit quality range will be Baa2 to B3 as measured by Moody's or BBB to B- by S&P. Securities denominated in local currency will be limited to 50% of the portfolio in aggregate, and, typically, non-dollar currency exposure will not be hedged. PGI will manage this portion of the Fund.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then, at the end of these periods, you either redeem all of your shares or you continue to hold your shares. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

THE COSTS OF INVESTING

Fees and Expenses of the Funds

This section describes the fees and expenses you may pay if you invest in Class A or C shares of the Fund. You may pay both one-time fees and ongoing fees. The table below shows the one-time fees you may pay directly if you invest in the Fund. The ongoing fees are the operating expenses of the Fund, which are described in a table provided with the description of the Fund. The ongoing operating expenses include fees paid to the Fund’s manager, underwriter and others who provide services to the Fund. These expenses reduce the value of each share you own.

Fees and expenses are important because they lower your earnings. However, low costs do not guarantee higher earnings. For example, a fund with no front-end sales charge may have higher ongoing expenses than a fund with such a sales charge. Before investing, you should be sure you understand the nature of different costs. Your Investment Representative can help you with this process. An example of the impact of both the one-time and ongoing fees on an investment in a Fund is also provided with the description of each Fund.

You may obtain more information about sales charge reductions and waivers through a link on the Fund’s website at www.PrincipalFunds.com, from the SAI, or from your Investment Representative.

One-time Fees 
•     You may pay a one-time sales charge for each purchase (Class A shares) or redemption (Class C shares). 
         Class A shares may be purchased at a price equal to the share price plus an initial sales charge. Investments of 
  $1 million or more of Class A shares are sold without an initial sales charge but may be subject to a contingent 
  deferred sales charge (CDSC) at the time of redemption. 
         Class C shares have no initial sales charge but may be subject to a CDSC. If you sell (redeem) shares and the 
 

CDSC is imposed, it will reduce the amount of sales proceeds. 

 

•     An excessive trading fee of 1.00% is charged on redemptions or exchanges of a Fund’s Class A and Class C 
       shares of $30,000, or more if the shares were purchased within 30 days of the redemption or exchange. The fee 
       does not apply to redemptions made: through an Automatic Exchange Election or a Systematic Withdrawal Plan; 
       due to a shareholder’s death or disability (as defined in the Internal Revenue Code); or to satisfy minimum 
       distribution rules imposed by the Internal Revenue Code. The fee is calculated as a percentage of market value of 
       the shares redeemed or exchanged at the time of redemption or exchange (without regard to the effect of any 
       CDSC that may apply). 

Ongoing Fees

Ongoing fees reduce the value of each share. Because they are ongoing, they increase the cost of investing in the Funds.

Each of the Funds pays ongoing fees to Principal and others who provide services to the Fund. These fees include:

·      Management Fee—Through the Management Agreement with the Fund, Principal has agreed to provide investment advisory services and corporate administrative services to the Funds.
 
·      Distribution Fee—The Fund has adopted a distribution plan under Rule 12b-1 of the Investment Company Act of 1940 for its Class A and Class C shares. Under the plan, Class A and Class C shares of the Fund pay a distribution fee based on the average daily net asset value (NAV) of the Fund. These fees pay distribution and other expenses for sale of Fund shares and for services provided to shareholders. Because they are ongoing fees, over time they will increase the cost of your investment and may cost you more than paying other types of sales charges.
 
·      Transfer Agent Fee—Principal Shareholder Services, Inc. (“PSS”) has entered into a Transfer Agency Agreement with the Fund under which PSS provides transfer agent services to the Class A and Class C shares of the Fund.
 
  These services are currently provided at cost.
 

Class A and Class C shares of the Fund also pay expenses of registering and qualifying shares for sale, the cost of producing and distributing reports and prospectuses to Class A and Class C shareholders, the cost of shareholder meetings held solely for Class A and Class C shares, and other operating expenses of the Fund.

The table below describes the one-time fees that you may pay directly if you buy or redeem shares of a Fund.

CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS

The Statement of Additional Information (SAI) contains additional information about investment strategies and their related risks.

Credit and Counterparty Risk

The Fund is subject to the risk that the issuer or guarantor of a fixed-income security or other obligation, the counterparty to a derivatives contract or repurchase agreement, or the borrower of a portfolio’s securities will be unable or unwilling to make timely principal, interest, or settlement payments, or otherwise to honor its obligations.

Liquidity Risk

A fund is exposed to liquidity risk when trading volume, lack of a market maker, or legal restrictions impair the fund’s ability to sell particular securities or close derivative positions at an advantageous price. Funds with principal investment strategies that involve securities of companies with smaller market capitalizations, foreign securities, derivatives, or securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk.

Management Risk

The Fund is actively managed by its investment advisor or sub-advisor(s). The performance of a fund that is actively managed will reflect in part the ability of the advisor or sub-advisor(s) to make investment decisions that are suited to achieving the fund’s investment objective. If the advisor’s or sub-advisor(s)’ strategies do not perform as expected, the fund could underperform other mutual funds with similar investment objectives or lose money.

Securities and Investment Practices

Market Volatility. Equity securities include common stocks, preferred stocks, convertible securities, depositary receipts, rights, and warrants. Common stocks, the most familiar type, represent an equity (ownership) interest in a corporation. The value of a company’s stock may fall as a result of factors directly relating to that company, such as decisions made by its management or lower demand for the company’s products or services. A stock’s value may also fall because of factors affecting not just the company, but also companies in the same industry or in a number of different industries, such as increases in production costs. The value of a company’s stock may also be affected by changes in financial markets that are relatively unrelated to the company or its industry, such as changes in interest rates or currency exchange rates. In addition, a company’s stock generally pays dividends only after the company invests in its own business and makes required payments to holders of its bonds and other debt. For this reason, the value of a company’s stock will usually react more strongly than its bonds and other debt to actual or perceived changes in the company’s financial condition or prospects. Stocks of smaller companies may be more vulnerable to adverse developments than those of larger companies.

Fixed-income securities include bonds and other debt instruments that are used by issuers to borrow money from investors. The issuer generally pays the investor a fixed, variable or floating rate of interest. The amount borrowed must be repaid at maturity. Some debt securities, such as zero coupon bonds, do not pay current interest, but are sold at a discount from their face values.

Interest Rate Changes. Fixed-income securities are sensitive to changes in interest rates. In general, fixed-income security prices rise when interest rates fall and fall when interest rates rise. Longer term bonds and zero coupon bonds are generally more sensitive to interest rate changes.

Credit Risk. Fixed-income security prices are also affected by the credit quality of the issuer. Investment grade debt securities are medium and high quality securities. Some bonds, such as lower grade or “junk” bonds, may have speculative characteristics and may be particularly sensitive to economic conditions and the financial condition of the issuers.

Repurchase Agreements and Loaned Securities

Although not a principal investment strategy, the Fund may invest a portion of its assets in repurchase agreements. Repurchase agreements typically involve the purchase of debt securities from a financial institution such as a bank, savings and loan association, or broker-dealer. A repurchase agreement provides that the Fund sells back to the seller

Principal Funds, Inc.  CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS  9 
www.principal.com     


and that the seller repurchases the underlying securities at a specified price on a specific date. Repurchase agreements may be viewed as loans by a Fund collateralized by the underlying securities. This arrangement results in a fixed rate of return that is not subject to market fluctuation while the Fund holds the security. In the event of a default or bankruptcy by a selling financial institution, the affected Fund bears a risk of loss. To minimize such risks, the Fund enters into repurchase agreements only with parties a Sub-Advisor deems creditworthy (those that are large, well-capitalized and well-established financial institutions). In addition, the value of the securities collateralizing the repurchase agreement is, and during the entire term of the repurchase agreement remains, at least equal to the repurchase price, including accrued interest.

The Fund may lend its portfolio securities to unaffiliated broker-dealers and other unaffiliated qualified financial institutions. These transactions involve a risk of loss to the Fund if the counterparty should fail to return such securities to the Fund upon demand or if the counterparty’s collateral invested by the Fund declines in value as a result of investment losses.

Bank Loans (also known as Senior Floating Rate Interests)

The Fund may invest in bank loans. Bank loans hold the most senior position in the capital structure of a business entity (the “Borrower”), are typically secured by specific collateral, and have a claim on the assets and/or stock of the Borrower that is senior to that held by subordinated debtholders and stockholders of the Borrower. Bank loans are typically structured and administered by a financial institution that acts as the agent of the lenders participating in the bank loan. Bank loans are rated below-investment-grade, which means they are more likely to default than investment-grade loans. A default could lead to non-payment of income which would result in a reduction of income to the fund and there can be no assurance that the liquidation of any collateral would satisfy the Borrower’s obligation in the event of non-payment of scheduled interest or principal payments, or that such collateral could be readily liquidated.

Bank loans pay interest at rates which are periodically reset by reference to a base lending rate plus a spread. These base lending rates are generally the prime rate offered by a designated U.S. bank or the London InterBank Offered Rate (LIBOR) or the prime rate offered by one or more major United States banks.

Bank loans generally are subject to mandatory and/or optional prepayment. Because of these mandatory prepayment conditions and because there may be significant economic incentives for the Borrower to repay, prepayments of senior floating rate interests may occur.

Currency Contracts

The Fund may enter into currency contracts, currency futures contracts and options, and options on currencies for hedging and other purposes. A forward currency contract involves a privately negotiated obligation to purchase or sell a specific currency at a future date at a price set in the contract. A Fund will not hedge currency exposure to an extent greater than the aggregate market value of the securities held or to be purchased by the Fund (denominated or generally quoted or currently convertible into the currency).

Hedging is a technique used in an attempt to reduce risk. If a Fund’s Sub-Advisor hedges market conditions incorrectly or employs a strategy that does not correlate well with the Fund’s investment, these techniques could result in a loss. These techniques may increase the volatility of a Fund and may involve a small investment of cash relative to the magnitude of the risk assumed. In addition, these techniques could result in a loss if the other party to the transaction does not perform as promised. There is also a risk of government action through exchange controls that would restrict the ability of the Fund to deliver or receive currency.

Forward Commitments

Although not a principal investment strategy, the Fund may enter into forward commitment agreements. These agreements call for the Fund to purchase or sell a security on a future date at a fixed price. The Fund may also enter into contracts to sell its investments either on demand or at a specific interval.

10  CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS  Principal Funds, Inc. 
    1-800-222-5852 


Warrants

The Fund may invest in warrants though it will not use such investments as a principal investment strategy. A warrant is a certificate granting its owner the right to purchase securities from the issuer at a specified price, normally higher than the current market price.

High Yield Securities

The Fund may invest in debt securities rated BB or lower by S&P or Ba or lower by Moody’s or, if not rated, determined to be of equivalent quality by the Sub-Advisor. Such securities are sometimes referred to as high yield or “junk bonds” and are considered speculative.

Investment in high yield bonds involves special risks in addition to the risks associated with investment in highly rated debt securities. High yield bonds may be regarded as predominantly speculative with respect to the issuer’s continuing ability to meet principal and interest payments. Moreover, such securities may, under certain circumstances, be less liquid than higher rated debt securities.

Analysis of the creditworthiness of issuers of high yield securities may be more complex than for issuers of higher quality debt securities. The ability of the Fund to achieve its investment objective may, to the extent of its investment in high yield bonds, be more dependent on such credit analysis than would be the case if the Fund were investing in higher quality bonds.

High yield bonds may be more susceptible to real or perceived adverse economic and competitive industry conditions than higher-grade bonds. The prices of high yield bonds have been found to be less sensitive to interest rate changes than more highly rated investments, but more sensitive to adverse economic downturns or individual corporate developments. If the issuer of high yield bonds defaults, the Fund may incur additional expenses to seek recovery.

The secondary market on which high yield bonds are traded may be less liquid than the market for higher-grade bonds. Less liquidity in the secondary trading market could adversely affect the price at which the Fund could sell a high yield bond and could adversely affect and cause large fluctuations in the daily price of the Fund’s shares. Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the value and liquidity of high yield bonds, especially in a thinly traded market.

The use of credit ratings for evaluating high yield bonds also involves certain risks. For example, credit ratings evaluate the safety of principal and interest payments, not the market value risk of high yield bonds. Also, credit rating agencies may fail to change credit ratings in a timely manner to reflect subsequent events. If a credit rating agency changes the rating of a portfolio security held by the Fund, the Fund may retain the security if the Sub-Advisor thinks it is in the best interest of shareholders.

Real Estate Investment Trusts

The Fund may invest in real estate investment trust securities, herein referred to as “REITs.” In addition, the Fund typically invests a significant portion of its net assets in REITs. REITs involve certain unique risks in addition to those risks associated with investing in the real estate industry in general (such as possible declines in the value of real estate, lack of availability of mortgage funds, or extended vacancies of property). Equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of any credit extended. REITs are dependent upon management skills, are not diversified, and are subject to heavy cash flow dependency, risks of default by borrowers, and self-liquidation. As an investor in a REIT, the Fund will be subject to the REIT’s expenses, including management fees, and will remain subject to the Fund’s advisory fees with respect to the assets so invested. REITs are also subject to the possibilities of failing to qualify for the special tax treatment accorded REITs under the Code, and failing to maintain their exemptions from registration under the 1940 Act.

Investment in REITs involves risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume, and may be subject to more abrupt or erratic price movements than larger company securities.

www.principal.com     


Initial Public Offerings (“IPOs”)

The Fund may invest in IPOs. An IPO is a company’s first offering of stock to the public. IPO risk is that the market value of IPO shares will fluctuate considerably due to factors such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer. The purchase of IPO shares may involve high transaction costs. IPO shares are subject to market risk and liquidity risk. In addition, the market for IPO shares can be speculative and/or inactive for extended periods of time. The limited number of shares available for trading in some IPOs may make it more difficult for the Fund to buy or sell significant amounts of shares without an unfavorable impact on prevailing prices. Investors in IPO shares can be affected by substantial dilution in the value of their shares by sales of additional shares and by concentration of control in existing management and principal shareholders.

When the Fund’s asset base is small, a significant portion of the Fund’s performance could be attributable to investments in IPOs because such investments would have a magnified impact on the Fund. As the Fund’s assets grow, the effect of the Fund’s investments in IPOs on the Fund’s performance probably will decline, which could reduce the Fund’s performance. Because of the price volatility of IPO shares, the Fund may choose to hold IPO shares for a very short period of time. This may increase the turnover of the Fund’s portfolio and lead to increased expenses to the Fund, such as commissions and transaction costs. By selling IPO shares, the Fund may realize taxable gains it will subsequently distribute to shareholders.

Derivatives

To the extent permitted by its investment objectives and policies, the Fund may invest in securities that are commonly referred to as derivative securities. Generally, a derivative is a financial arrangement, the value of which is derived from, or based on, a traditional security, asset, or market index. Certain derivative securities are described more accurately as index/structured securities. Index/structured securities are derivative securities whose value or performance is linked to other equity securities (such as depositary receipts), currencies, interest rates, indices, or other financial indicators (reference indices).

Some derivatives, such as mortgage-related and other asset-backed securities, are in many respects like any other investment, although they may be more volatile or less liquid than more traditional debt securities.

There are many different types of derivatives and many different ways to use them. Futures and options are commonly used for traditional hedging purposes to attempt to protect a Fund from exposure to changing interest rates, securities prices, or currency exchange rates and for cash management purposes as a low-cost method of gaining exposure to a particular securities market without investing directly in those securities. The Funds may enter into put or call options, futures contracts, options on futures contracts, over-the-counter swap contracts (e.g., interest rate swaps, total return swaps and credit default swaps), and forward currency contracts for both hedging and non-hedging purposes.

Generally, the Fund may not invest in a derivative security unless the reference index or the instrument to which it relates is an eligible investment for the Fund or the reference currency relates to an eligible investment for the Fund.

The return on a derivative security may increase or decrease, depending upon changes in the reference index or instrument to which it relates. The risks associated with derivative investments include:

•      the risk that the underlying security, interest rate, market index, or other financial asset will not move in the direction 
       the Sub-Advisor anticipated; 
•      the possibility that there may be no liquid secondary market which may make it difficult or impossible to close out a 
       position when desired; 
•      the risk that adverse price movements in an instrument can result in a loss substantially greater than a Fund’s initial 
       investment; and 
•      the possibility that the counterparty may fail to perform its obligations. 

Exchange Traded Funds (ETFs)

These are a type of index or actively managed fund bought and sold on a securities exchange. An ETF trades like common stock. Shares in an index ETF represent an interest in a fixed portfolio of securities designed to track a particular market index. The Fund could purchase shares issued by an ETF to temporarily gain exposure to a portion of the U.S. or a foreign market while awaiting purchase of underlying securities. The risks of owning an ETF generally

    1-800-222-5852 


reflect the risks of owning the underlying securities they are designed to track, although ETFs have management fees that increase their costs.

Convertible Securities

Convertible securities are fixed-income securities that a Fund has the right to exchange for equity securities at a specified conversion price. The option allows the Fund to realize additional returns if the market price of the equity securities exceeds the conversion price. For example, the Fund may hold fixed-income securities that are convertible into shares of common stock at a conversion price of $10 per share. If the market value of the shares of common stock reached $12, the Fund could realize an additional $2 per share by converting its fixed-income securities.

Convertible securities have lower yields than comparable fixed-income securities. In addition, at the time a convertible security is issued the conversion price exceeds the market value of the underlying equity securities. Thus, convertible securities may provide lower returns than non-convertible fixed-income securities or equity securities depending upon changes in the price of the underlying equity securities. However, convertible securities permit the Fund to realize some of the potential appreciation of the underlying equity securities with less risk of losing its initial investment.

The Funds treat convertible securities as both fixed-income and equity securities for purposes of investment policies and limitations because of their unique characteristics. The Funds may invest in convertible securities without regard to their ratings.

Foreign Investing

As a principal investment strategy, the Fund may invest Fund assets in securities of foreign companies. For the purpose of this restriction, foreign companies are:

·      companies with their principal place of business or principal office outside the U.S. or
 
·      companies for which the principal securities trading market is outside the U.S.
 

Foreign companies may not be subject to the same uniform accounting, auditing, and financial reporting practices as are required of U.S. companies. In addition, there may be less publicly available information about a foreign company than about a U.S. company. Securities of many foreign companies are less liquid and more volatile than securities of comparable U.S. companies. Commissions on foreign securities exchanges may be generally higher than those on U.S. exchanges.

Foreign markets also have different clearance and settlement procedures than those in U.S. markets. In certain markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct these transactions. Delays in settlement could result in temporary periods when a portion of Fund assets is not invested and earning no return. If the Fund is unable to make intended security purchases due to settlement problems, the Fund may miss attractive investment opportunities. In addition, the Fund may incur a loss as a result of a decline in the value of its portfolio if it is unable to sell a security.

With respect to certain foreign countries, there is the possibility of expropriation or confiscatory taxation, political or social instability, or diplomatic developments that could affect the Fund’s investments in those countries. In addition, the Fund may also suffer losses due to nationalization, expropriation or differing accounting practices and treatments. Investments in foreign securities are subject to laws of the foreign country that may limit the amount and types of foreign investments. Changes of governments or of economic or monetary policies, in the U.S. or abroad, changes in dealings between nations, currency convertibility, or exchange rates could result in investment losses for the Fund. Finally, even though certain currencies may be convertible into U.S. dollars, the conversion rates may be artificial relative to the actual market values and may be unfavorable to Fund investors.

Foreign securities are often traded with less frequency and volume, and therefore may have greater price volatility, than is the case with many U.S. securities. Brokerage commissions, custodial services, and other costs relating to investment in foreign countries are generally more expensive than in the U.S. Though the Fund intends to acquire the securities of foreign issuers where there are public trading markets, economic or political turmoil in a country in which the Fund has a significant portion of its assets or deterioration of the relationship between the U.S. and a foreign country may negatively impact the liquidity of the Fund’s portfolio. The Fund may have difficulty meeting a large

Principal Funds, Inc.  CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS  13 
www.principal.com     


number of redemption requests. Furthermore, there may be difficulties in obtaining or enforcing judgments against foreign issuers.

The Fund may choose to invest in a foreign company by purchasing depositary receipts. Depositary receipts are certificates of ownership of shares in a foreign-based issuer held by a bank or other financial institution. They are alternatives to purchasing the underlying security but are subject to the risks of the foreign securities to which they relate.

Investments in companies of developing (also called “emerging”) countries are subject to higher risks than investments in companies in more developed countries. These risks include:

·      increased social, political, and economic instability;
 
·      a smaller market for these securities and low or nonexistent volume of trading that results in a lack of liquidity and in greater price volatility;
 
·      lack of publicly available information, including reports of payments of dividends or interest on outstanding securities;
 
·      foreign government policies that may restrict opportunities, including restrictions on investment in issuers or industries deemed sensitive to national interests;
 
·      relatively new capital market structure or market-oriented economy;
 
·      the possibility that recent favorable economic developments may be slowed or reversed by unanticipated political or social events in these countries;
 
·      restrictions that may make it difficult or impossible for the Fund to vote proxies, exercise shareholder rights, pursue legal remedies, and obtain judgments in foreign courts; and
 
·      possible losses through the holding of securities in domestic and foreign custodial banks and depositories.
 

In addition, many developing countries have experienced substantial and, in some periods, extremely high rates of inflation for many years. Inflation and rapid fluctuations in inflation rates have had and may continue to have negative effects on the economies and securities markets of those countries.

Repatriation of investment income, capital, and proceeds of sales by foreign investors may require governmental registration and/or approval in some developing countries. The Fund could be adversely affected by delays in or a refusal to grant any required governmental registration or approval for repatriation.

Further, the economies of developing countries generally are heavily dependent upon international trade and, accordingly, have been and may continue to be adversely affected by trade barriers, exchange controls, managed adjustments in relative currency values, and other protectionist measures imposed or negotiated by the countries with which they trade.

Small and Medium Capitalization Companies

The Fund may hold securities of small and medium capitalization companies but not as a principal investment strategy. The international funds invest in the securities of foreign companies without regard to the market capitalizations of those companies. Market capitalization is defined as total current market value of a company’s outstanding common stock. Investments in companies with smaller market capitalizations may involve greater risks and price volatility (wide, rapid fluctuations) than investments in larger, more mature companies. Small companies may be less significant within their industries and may be at a competitive disadvantage relative to their larger competitors. While smaller companies may be subject to these additional risks, they may also realize more substantial growth than larger or more established companies.

Smaller companies may be less mature than larger companies. At this earlier stage of development, the companies may have limited product lines, reduced market liquidity for their shares, limited financial resources, or less depth in management than larger or more established companies. Unseasoned issuers are companies with a record of less than three years continuous operation, including the operation of predecessors and parents. Unseasoned issuers by their nature have only a limited operating history that can be used for evaluating the company’s growth prospects. As a result, investment decisions for these securities may place a greater emphasis on current or planned product lines and the reputation and experience of the company’s management and less emphasis on fundamental valuation factors than would be the case for more mature growth companies.

Temporary Defensive Measures

From time to time, as part of its investment strategy, the Fund may invest without limit in cash and cash equivalents for temporary defensive purposes in response to adverse market, economic or political conditions. To the extent that the Fund is in a defensive position, it may lose the benefit of upswings and limit its ability to meet its investment objective. For this purpose, cash equivalents include: bank notes, bank certificates of deposit, bankers’ acceptances, repurchase agreements, commercial paper, and commercial paper master notes which are floating rate debt instruments without a fixed maturity. In addition, a Fund may purchase U.S. government securities, preferred stocks, and debt securities, whether or not convertible into or carrying rights for common stock.

There is no limit on the extent to which the Fund may take temporary defensive measures. In taking such measures, the Fund may fail to achieve its investment objective.

Portfolio Turnover

“Portfolio Turnover” is the term used in the industry for measuring the amount of trading that occurs in a Fund’s portfolio during the year. For example, a 100% turnover rate means that on average every security in the portfolio has been replaced once during the year. Funds that engage in active trading may have high portfolio turnover.

Funds with high turnover rates (more than 100%) often have higher transaction costs (that are paid by the Fund) which may have an adverse impact on Fund performance and may generate short-term capital gains (on which taxes may be imposed even if no shares of the Fund are sold during the year).

Please consider all the factors when you compare the turnover rates of different funds. A fund with consistently higher total returns and higher turnover rates than another fund may actually be achieving better performance precisely because the managers are active traders.

Duties of Principal and Sub-Advisors

Principal or the Sub-Advisor provides the Directors of the Principal Investors Fund with a recommended investment program. The program must be consistent with the Fund’s investment objective and policies. Within the scope of the approved investment program, the Sub-Advisor advises the Fund on its investment policy and determines which securities are bought or sold, and in what amounts.

This Fund has multiple Sub-Advisors. Principal determines the portion of the Fund’s assets each Sub-Advisor will manage and may, from time-to-time, reallocate Fund assets among the Sub-Advisors. The decision to do so may be based on a variety of factors, including but not limited to: the investment capacity of each Sub-Advisor, portfolio diversification, volume of net cash flows, fund liquidity, investment performance, investment strategies, changes in each Sub-Advisor’s firm or investment professionals or changes in the number of Sub-Advisors. Ordinarily, reallocations of Fund assets among Sub-Advisors will generally occur as a Sub-Advisor liquidates assets in the normal course of portfolio management and with net new cash flows; however, at times, existing Fund assets may be reallocated among Sub-Advisors.

Fees Paid to the Manager

The Fund pays Principal a fee for its services, which includes any fee Principal pays to the Sub-Advisor. The fee the Fund will pay (as a percentage of the average daily net assets) is:

  0.80% on the first $500 million
0.78% on the next $500 million
0.76% on the next $500 million
0.75% on the next $500 million
0.73% on the next $1.0 billion
0.70% on assets over $3.0 billion

A discussion regarding the basis for the Board of Directors approving the management agreement with Principal and the sub-advisory agreements with these Sub-Advisors will be included in the annual report to shareholders for the fiscal year ended October 31, 2008, which will be available 60 days after that date.

Under an order received from the SEC, the Fund and Principal, may enter into and materially amend agreements with Sub-Advisors, other than those affiliated with Principal, without obtaining shareholder approval. For any Fund that is relying on that order, Principal may, without obtaining shareholder approval:

·      hire one or more Sub-Advisors;
 
·      change Sub-Advisors; and
 
·      reallocate management fees between itself and Sub-Advisors.
 
18  MANAGEMENT OF THE FUNDS  Principal Funds, Inc. 
    1-800-222-5852 


Principal has ultimate responsibility for the investment performance of each Fund that utilizes a Sub-Advisor due to its responsibility to oversee Sub-Advisors and recommend their hiring, termination, and replacement. No Fund will rely on the order until it receives approval from its shareholders or, in the case of a new Fund, the Fund’s sole initial shareholder before the Fund is available to the other purchasers, and the Fund states in its prospectus that it intends to rely on the order.

The shareholders of the Fund have approved the Fund’s reliance on the order; however, the Fund does not intend to rely on the order.

PURCHASE OF FUND SHARES

Shares of the Funds are generally purchased through persons employed by or affiliated with broker/dealer firms (“‘Investment Representatives”). Investment Representatives may establish shareholder accounts according to their procedures or they may establish shareholder accounts directly with the Fund by visiting www.PrincipalFunds.com to obtain the appropriate forms. An application is included with this prospectus. A different application is needed for a Principal Investors Fund IRA, Coverdell Education Savings Account, 403(b), HSA, SEP, SIMPLE, SAR-SEP, or certain employee benefit plans. These applications are available on www.PrincipalFunds.com.

An investment in the Fund may be held in various types of accounts, including individual, joint ownership, trust, and business accounts. The Fund also offers a range of custodial accounts for those who wish to invest for retirement and/ or education expenses. Prospective shareholders should consult with their Investment Representative prior to making decisions about the account and type of investment that are appropriate for them. The Fund reserves the right to refuse any order for the purchase of shares, including those by exchange. Principal may recommend to the Board, and the Board may elect, to close certain funds to new investors or close certain funds to new and existing investors.

Payments are to be made via personal or financial institution check (for example, a bank or cashier’s check). We reserve the right to refuse any payment that we feel presents a fraud or money laundering risk. Examples of the types of payments we will not accept are cash, money orders, travelers’ checks, credit card checks, and foreign checks.

Making an Investment

Principal Funds has a minimum initial investment amount of $1,000 and a minimum subsequent investment amount of $100. Initial and subsequent investment minimums apply on a per-fund basis for each Fund in which a shareholder invests.

Shareholders must meet the minimum initial investment amount of $1,000 unless an Automatic Investment Plan (“‘AIP”) is established. With an AIP, the minimum initial investment is $100. Accounts or automatic payroll deduction plans established with an AIP that do not meet the minimum initial investment must maintain subsequent automatic investments that total at least $1,200 annually. Minimums may be waived on accounts set up for: certain employee benefit plans; retirement plans qualified under Internal Revenue Code Section 401(a); payroll deduction plans submitting contributions in an electronic format devised and/or approved by the Fund; Principal Funds asset allocation programs; and purchases through an omnibus account with a broker-dealer, investment advisor, or other financial institution.

Payment. Payment for Fund shares is generally made via personal check or cashiers check. We consider your purchase of Fund shares by check to be your authorization to make an automated clearing house (“ACH”) debit entry to your account. Shares purchased by check may be sold only after the check has cleared your bank, which may take up to 7 calendar days.

The Fund may, in their discretion and under certain limited circumstances, accept securities as payment for Fund shares at the applicable net asset value (“‘NAV”). For federal income tax purposes, a purchase of shares with securities will be treated as a sale or exchange of such securities on which the investor will generally realize a taxable gain or loss. The Fund will value securities used to purchase its shares using the same method the Fund uses to value its portfolio securities as described in this prospectus.

CHOOSING A SHARE CLASS

Your Investment Representative will help you choose the Fund that is appropriate for you based upon your investment objective, risk tolerance and other factors. Your Investment Representative can also help you choose the share class that is appropriate for you. Investment Representatives may receive different compensation depending upon which class of shares you purchased. The sales charge for Class A shares may be reduced or eliminated for certain types of purchases or for purchases of sufficient size. Your Investment Representative can help you determine whether your investment qualifies for a reduced sales charge.

This prospectus offers two share classes: Class A and Class C. Class C shares are not available to retirement plans qualified under IRC section 401(a) that are not already investing in Class C shares of other Funds of Principal Funds, but are available to new participants in plans that currently invest in Class C shares of the Fund. Highlights of each Fund’s share classes and information regarding sales charges and dealer reallowances are provided below.

Each class has different costs associated with buying, redeeming, and holding shares. Which class is best for you depends upon:

  the dollar amount you are investing, 
  the amount of time you plan to hold the investment, and 
  any plans to make additional investments in the Principal Funds. 

Please consult with your Investment Representative before choosing the class of shares that is most appropriate for you. Before you invest, you should understand the characteristics of each share class so you can be sure to choose the class that is right for you.

If you are making subsequent purchases into your existing Principal Funds Class C share accounts and the combined value of the subsequent investment and your existing Class A, Class B, Class C, and Class J share accounts combined for Rights of Accumulation purposes exceeds $1,000,000, the subsequent investment will be applied to purchase Class A shares of the Fund(s) you have selected.

CLASS A SHARES

Initial Sales Charge

·      You generally pay a sales charge on an investment in Class A shares, which varies based on the amount invested and the Fund selected.
 
·      If you invest more than $100,000, the sales charge is reduced.
 
·      You might be eligible for a reduced sales charge. See “Sales Charge Waiver or Reduction (Class A shares).”
 
·      Sales charges might be reduced under the Rights of Accumulation or Statement of Intent, as described below.
 

Sales Charge Waiver or Reduction (Class A shares)

Class A shares of the Funds may be purchased without a sales charge or at a reduced sales charge. The Funds reserve the right to change or stop offering shares in this manner at any time for new accounts and with a 60-day notice to shareholders of existing accounts.

To receive a reduction in your Class A initial sales charge, you or your Investment Representative must let the Fund know at the time you purchase shares that you qualify for such a reduction. If you or your Investment Representative do not let the Fund know that you are eligible for a reduction, you may not receive a sales charge discount to which you are otherwise entitled. It may be necessary for you to provide information and records, such as account statements.

Purchase Without an Initial Sales Charge (Class A shares)

·      No initial sales charge will apply to purchases of over $500,000, although a 0.75% contingent deferred sales charge may apply to redemptions made within 18 months after purchase.
 
·      No initial sales charge will apply to shares purchased with the proceeds of redemptions of Class A shares of the Funds or was waived in connection with a Required Minimum Distribution, involuntary redemption or due to the death of the shareholder, within 60 days of redemption. It is the responsibility of the shareholder to notify the Fund at the time of repurchase if the purchase proceeds are from a redemption of the Fund within the past 60 days.
 
·      A Fund’s Class A shares may be purchased without a sales charge by the following individuals, groups, and/or entities:
 
  ·      by its current and former Directors, member companies of the Principal Financial Group, and their active or retired employees, officers, directors, brokers, or agents (for the life of the account). This also includes their immediate family members (spouse, domestic partner, children (regardless of age), and parents), and trusts created by or primarily for the benefit of these individuals;
 
  ·      by the Premier Credit Union;
 
  ·      by non-ERISA clients of Principal Global Investors LLC;

  ·      through a “wrap account” offered by Princor or through broker-dealers, investment advisors, and other financial institutions that have entered into an agreement with Princor or the Distributor which includes a requirement that such shares be sold for the benefit of clients participating in a “wrap account” or similar program under which clients pay a fee to the broker-dealer, investment advisor, or financial institution;
 
  ·      to fund non-qualified plans administered by a member company of the Principal Financial Group pursuant to a written service agreement;
 
  ·      by accounts established as a result of the conversion of Class R shares of the Fund;
 
  ·      by any investor who buys Class A shares through an omnibus account with certain financial intermediaries, such as a bank or other financial institution, that does not accept or charge the initial sales charge. In addition, the CDSC generally applicable to redemptions of shares made within 18 months after purchase of $1 million or

·      by former Washington Mutual employees who establish IRAs involving assets from a Washington Mutual retirement or benefit plan, and subsequent investments into such accounts;
 
·      by participants in, or by purchases through, employer-sponsored retirement or benefit plans which were eligible to purchase shares without payment of a sales charge of a predecessor fund prior to the date the successor fund commenced operations; provided, however, that the third party administrator or other service provider the sponsor of the retirement or benefit plan employs utilizes a system for processing purchases of shares that will accommodate waiver of the Fund’s sales charge;
 
·      by individuals who were eligible to purchase shares without payment of a sales charge of a predecessor fund (a fund previously included in the WM Group of Funds) prior to the date the successor fund commenced operations;
 
·      by clients of registered investment advisors that have entered into arrangements with Princor or the Distributor providing for the shares to be used in particular investment products made available to such clients and for which such registered investment advisors may charge a separate fee;
 
·      to qualified retirement plans where the plan’s R-1 or R-2 share investments were redesignated A share investments;

·      new participants in such Employer Sponsored Plans that had at least $2.8 million in Principal Funds as of January 12, 2007 can purchase Class A shares within the plan at net asset value provided the participant notes that he or she meets this qualification on the participant’s initial application to purchase shares.
 

Purchase at a Reduced Initial Sales Charge (Class A Shares)

1)  Rights of Accumulation. The sales charge varies with the size of your purchase. Purchases made by you, your 
  spouse or domestic partner, your children, the children of your spouse or domestic partner up to and including the 
  age of 25 and/or a trust created by or primarily for the benefit of such persons (together “a Qualified Purchaser”) 
  will be combined along with the value of existing Class A, B, C and J shares of Principal Funds owned by such 
  persons, to determine the applicable sales charge. Class A shares of Money Market Fund are not included in the 
  calculation unless they were acquired in exchange from other Principal Funds shares. If the total amount being 
  invested in the Principal Funds is near a sales charge breakpoint, you should consider increasing the amount 
  invested to take advantage of a lower sales charge. 
 
2) Statement of Intent (SOI). Qualified Purchasers may obtain reduced sales charges by signing an SOI. The SOI is a 
  nonbinding obligation on the Qualified Purchaser to purchase the full amount indicated in the SOI. Purchases 
  made by you, your spouse or domestic partner, or the children of you, your spouse or domestic partner up to and 
  including the age of 25 and/or a trust created by or primarily for the benefit of such persons (together “a Qualified 
  Purchaser”) will be combined along with the value of existing Class A, B, C and J shares of Principal Funds owned 
  by such persons. Purchases of Class A shares of Money Market Fund are not included. The sales charge is based 
  on the total amount to be invested in a 13 month period. If the intended investment is not made (or shares are sold 
  during the 13 month period), sufficient shares will be sold to pay the additional sales charge due. An SOI is not 
  available for 401(a) plan purchases. 
 
3)  The maximum sales charge that applies to purchases of Class A shares by qualified plans administered by 
  Expertplan, Inc. that were previously converted from B share plans is the sales charge that applies to purchases of 
  at least $250,000 but less than $500,000 as described in the sales charge tables below; the regular sales charge 
  applies to purchases of $500,000 or more in such accounts and to all purchases of the Short-Term Bond, Short- 
  Term Income, Ultra Short Bond and LargeCap S&P 500 Index Fund shares. 

22  CLASS A SHARES  Principal Funds, Inc. 
    1-800-222-5852 


4)  Employer Sponsored Plans. The maximum sales charge for all purchases made in an account that is included in a 
  SIMPLE IRA, SEP, SAR-SEP, non-qualified deferred compensation, payroll deduction or 403(b) plan (“Employer 
  Sponsored Plan”) established prior to March 1, 2002 with Principal Management Corporation as the Funds’ transfer 
  agent, is the sales charge that applies to purchases of at least $100,000 but less than $250,000 as described in the 
  sales charge tables below; the regular sales charge applies to purchases of $250,000 or more in such accounts 
  and to all purchases of the Short-Term Bond, Short-Term Income, Ultra Short Bond and LargeCap S&P 500 Index 
  Fund shares. The reduced sales charge applies to purchases made by or on behalf of participants to such plans 
  who become participants on or before July 28, 2007. 

Purchase of Class A Shares. The offering price for Class A shares is the NAV next calculated after receipt of an investor’s order in proper form by the Fund or its servicing agent, plus any applicable initial sales charge as shown in the tables below. The right-hand column in each table indicates what portion of the sales charge is paid to Investment Representatives and their brokerage firms (“dealers”) for selling Class A shares. For more information regarding compensation paid to dealers, see “Distribution Plan and Additional Information Regarding Intermediary Compensation.”

There is no sales charge on purchases of Class A shares of the fund if the purchase is made within 60 days of the redemption of Class A shares of the Fund or described in “Redemption of Fund Shares” provided the shareholder notifies the Fund that the purchase proceeds are from the redemption of Class A shares. Class A shares of the other Funds are purchased with a sales charge that is a variable percentage based on the amount of the purchase. There is no sales charge on shares of a Fund purchased with reinvested dividends or other distributions. Your sales charge may be reduced for larger purchases as indicted below.

Class A Sales Charges(1)
       
    Sales Charge as % of: Dealer Allowance as % 
    Offering  Amount  of 
Amount of Purchase    Price  Invested  Offering Price 
$0 to $100,000    3.75% 3.90% 3.25%
$100,000 to $249,999    2.75% 2.83% 2.25%
$250,000 to $499,999    1.50% 1.52% 1.00%
Over $500,000    0.00% 0.00%       0.00%(2)

(1)     Because of rounding in the calculation of the offering price, the actual maximum front-end sales charge paid by an investor may be higher or lower than the percentages noted above.
 
(2)      The Distributor may pay authorized dealers commissions on purchases of Class A shares over $500,000 calculated as follows: 0.75% on pur- chases between $500,000 and $3 million, 0.50% on the next $2 million, 0.35% on the next $5 million, and 0.25% on the amount purchased in excess of $10 million. The commission rate is determined based on the purchase amount combined with the current market value of existing investments in Class A, B, and C shares.

Contingent Deferred Sales Charge (“CDSC”) on Class A Shares. Class A shares purchased in excess of $500,000 or more for Global Diversified Income are generally subject to a CDSC of 0.75% if the shares are redeemed during the first 18 months after purchase, unless the dealer, at its discretion, has waived the commission. The Distributor may pay authorized dealers commissions up to 0.75% of the price of such purchases. The CDSC may be waived for redemptions of Class A shares as described under “CDSC Calculation and Waivers.”

Pricing and Sales Charge information is available, free of charge, on our website at www.principalfunds.com.

CLASS C SHARES

Class C shares may not be suitable for large investments. Due to the higher expenses associated with Class C shares, it may be more advantageous for investors currently purchasing, intending to purchase, or with existing assets

Principal Funds, Inc.  CLASS C SHARES  23 
www.principal.com     


in amounts that may qualify for a reduced sales charge on Class A shares, including through Rights of Accumulation and/or Statement of Intent, to purchase Class A shares.

The Fund seeks to prevent investments in Class C shares by shareholders with at least $1 million of investments in the Principal Funds eligible for inclusion pursuant to Rights of Accumulation. The Fund will consider initial purchases of $1 million or more, and subsequent purchases that would result in an investment of $1 million or more when combined with a shareholder’s existing account values, as determined using Rights of Accumulation, as a purchase of Class A shares. Class C shares are not available to retirement plans qualified under IRC section 401(a) that are not already investing in Class C shares of the Fund, but are available to new participants in plans that currently invest in Class C shares of the Fund.

The offering price for Class C shares is the NAV next calculated after receipt of an investor’s order in proper form by the Fund or its servicing agent, with no initial sales charge.

·      A CDSC of 1.00% may apply if redeemed during the first 12 months after purchase. Class C shares do not convert to Class A shares, so future distribution and service fees do not decrease.
 
·      Class C shares have higher annual expenses than Class A shares because they are subject to distribution fees.
 

Within 60 days after redemption of Class C shares, the proceeds may be reinvested in other Class C shares at NAV. It is the responsibility of the shareholder to notify the Fund at the time of reinvestment if the purchase proceeds are from redemption of Class C shares. (If a CDSC has been waived in connection with a Required Minimum Distribution, involuntary redemption, or the death of a shareholder, redemption proceeds may not be used to repurchase Class C shares. Following these circumstances, redemption proceeds may be used to purchase Class A shares at NAV.

The Distributor currently pays authorized dealers commissions of up to 1.00% of the amount invested in Class C shares.

Contingent Deferred Sales Charge (“CDSC”) on Class C Shares. Each initial and subsequent purchase of Class C shares is subject to a CDSC of 1.00% for a period of 12 months from the date of purchase. Shares will be redeemed first from shares purchased through reinvested dividends and capital gain distributions, which are not subject to the CDSC, and then in order of purchase. The CDSC may be waived for redemptions of Class C shares as described under “CDSC Calculation and Waivers.”

Pricing and Sales Charge information is available, free of charge, on our website at www.principalfunds.com.

CDSC CALCULATION AND WAIVERS

The CDSC is based on the lesser of the market value at the time of redemption or the initial purchase price of the shares sold. The CDSC does not apply to shares purchased with reinvested dividends or other distributions. The CDSC is not charged on exchanges. However, the original purchase date of the shares from which an exchange is made determines if the newly acquired shares are subject to the CDSC when they are sold.

If you sell some but not all of the shares in your account, the shares not subject to a sales charge will be sold first. Other shares will be sold in the order purchased (first in, first out). The CDSC does not apply to shares redeemed according to a systematic withdrawal plan limited to no more than 1.00% per month (measured cumulatively for non-monthly plans) of the value of the Fund account at the time, and beginning on the date, the systematic withdrawal plan is established.

The CDSC is waived on shares which are sold:

·      within 90 days after an account is re-registered due to a shareholder’s death;
 
·      due to the shareholder’s disability, as defined in the Internal Revenue Code provided the shares were purchased prior to the disability;
 
·      from retirement plans to satisfy minimum distribution rules under the Internal Revenue Code;
 
·      to pay surrender charges;
 
·      to pay retirement plan fees;

·      involuntarily from small balance accounts;
 
·      from a retirement plan to assure the plan complies with Sections 401(k), 401(m), 408(k), or 415 of the Internal Revenue Code; or
 
·      from retirement plans to satisfy excess contribution rules under the Internal Revenue Code.
 
NOTE:  To have your CDSC waived, you must let your advisor or the Fund know at the time you redeem shares that 
  you qualify for such a waiver.

REDEMPTION OF FUND SHARES

After you place a sell order in proper form, shares are sold using the next share price calculated. The amount you receive will be reduced by any applicable CDSC or excessive trading fee. There is no additional charge for a sale of shares however; you will be charged a $10 wire fee if you have the sale proceeds wired to your bank. Generally, the sale proceeds are sent out on the next business day* after the sell order has been placed. It may take additional business days for your financial institution to post this payment to your account at that financial institution. At your request, the check will be sent overnight (a $15 overnight fee will be deducted from your account unless other arrangements are made). Shares purchased by check may be sold only after the check has cleared your bank, which may take up to 7 calendar days. A sell order from one owner is binding on all joint owners.

* a day when the NYSE is open for normal business

Distributions from IRA, SEP, SIMPLE, 403(b) and SAR-SEP accounts may be taken as:

·      lump sum of the entire interest in the account,
 
·      partial interest in the account, or
 
·      periodic payments of either a fixed amount or an amount based on certain life expectancy calculations.
 

Tax penalties may apply to distributions before the participant reaches age 59 1/2.

Sale of shares may create a gain or a loss for federal (and state) income tax purposes. You should maintain accurate records for use in preparing your income tax returns.

Generally, sales proceeds checks are:

·      payable to all owners on the account (as shown in the account registration) and
 
·      mailed to the address on the account (if not changed within last 30 days) or previously authorized bank account.
 

For other payment arrangements, please call Principal Funds. You should also call Principal Funds for special instructions that may apply to sales from accounts:

·      when an owner has died
 
·      for certain employee benefit plans; or
 
·      owned by corporations, partnerships, agents, or fiduciaries.
 

Payment for shares sold is generally sent the business day after the sell order is received. Under unusual circumstances, Principal Funds may suspend redemptions, or postpone payment for more than seven days, as permitted by federal securities law.

Within 60 calendar days after the sale of shares, you may reinvest the amount of the sale proceeds into any Principal Funds Class A shares without a sales charge if the shares that were sold were Class A shares. Within 60 calendar days after the sale of Class C shares, any amount of the sale proceeds that you reinvest will be reinvested in Class C shares; shares purchased by redemption proceeds are not subject to the twelve month CDSC. It is the responsibility of the shareholder to notify the Fund at the time of repurchase if the purchase proceeds are from a redemption of the Fund within the past 60 days.

The transaction is considered a sale for federal (and state) income tax purposes even if the proceeds are reinvested. If a loss is realized on the sale, the reinvestment may be subject to the “wash sale” rules resulting in the postponement of the recognition of the loss for tax purposes.

Distributions in Kind. Payment for shares of the Fund tendered for redemption is ordinarily made by check. However, the Fund may determine that it would be detrimental to the remaining shareholders of the Fund to make payment of a redemption order wholly or partly in cash. Under certain circumstances, therefore, the Fund may pay the redemption proceeds in whole or in part by a distribution “in kind” of securities from the Fund’s portfolio in lieu of cash. If the Fund pays the redemption proceeds in kind, the redeeming shareholder might incur brokerage or other costs in selling the securities for cash. The Fund will value securities used to pay redemptions in kind using the same method the Fund uses to value its portfolio securities as described in this prospectus.

Excessive Trading fee. An excessive trading fee may apply to redemptions made within 30 days of purchase as described in “Frequent Purchases and Redemptions.” If excessive trading is deemed to be occurring, additional restrictive actions may be taken, as described in the “Frequent Purchases and Redemption” section.

EXCHANGE OF FUND SHARES

Your shares in the Fund may be exchanged without a sales charge or CDSC for the same class of any other Principal Fund. The Fund reserves the right to revise or terminate the exchange privilege at any time. Notice will be provided to shareholders of any such change, to the extent required by law.

You may exchange shares by:

·      sending a written request to Principal Funds, P.O. Box 8024, Boston, MA 02266-8024,
 
·      via the Internet at www.PrincipalFunds.com, or

General

·      An exchange by any joint owner is binding on all joint owners.
 
·      If you do not have an existing account in the Fund to which the exchange is being made, a new account is established. The new account has the same owner(s), dividend and capital gain options and dealer of record as the account from which the shares are being exchanged.
 
·      All exchanges are subject to the minimum investment and eligibility requirements of the Fund being acquired.
 
·      You may acquire shares of a Fund only if its shares are legally offered in your state of residence.
 
·      For an exchange to be effective the day we receive your instruction, we must receive the instruction in good order at our transaction processing center in Canton, Massachusetts before the close of normal trading on the NYSE
 
  (generally 3 p.m. Central Time).
 

When money is exchanged or transferred from one account registration or tax identification number to another, the account holder is relinquishing his or her rights to the money. Therefore exchanges and transfers can only be accepted by telephone if the exchange (transfer) is between:

·      accounts with identical ownership,
 
·      an account with a single owner to one with joint ownership if the owner of the single owner account is also an owner of the account with joint ownership,
 
·      a single owner to a UTMA account if the owner of the single owner account is also the custodian on the UTMA account, or
 
·      a single or jointly owned account to an IRA account to fund the yearly IRA contribution of the owner (or one of the owners in the case of a jointly owned account).

    1-800-222-5852 


The exchange is treated as a sale of shares for federal (and state) income tax purposes and may result in a capital gain or loss. Income tax rules regarding the calculation of cost basis may make it undesirable in certain circumstances to exchange shares within 90 days of their purchase.

Fund shares used to fund an employee benefit plan may be exchanged only for shares of other Funds available to employee benefit plans. Such an exchange must be made by following the procedures provided in the employee benefit plan and the written service agreement.

Excessive Trading fee. An excessive trading fee may apply to exchanges made within 30 days of purchase as described in “Frequent Purchases and Redemptions.” If excessive trading is deemed to be occurring, additional restrictive actions may be taken, as described below.

FREQUENT PURCHASES AND REDEMPTIONS

The Fund is not designed for, and does not knowingly accommodate, frequent purchases and redemptions of fund shares by investors. If you intend to trade frequently and/or use market timing investment strategies, you should not purchase this Fund.

Frequent purchases and redemptions pose a risk to the Fund because they may:

·      Disrupt the management of the Fund by:
 
  ·      forcing the Fund to hold short-term (liquid) assets rather than investing for long term growth, which results in lost investment opportunities for the Fund; and
 
  ·      causing unplanned portfolio turnover;
 
·      Hurt the portfolio performance of the Fund; and
 
·      Increase expenses of the Fund due to:
 
  ·      increased broker-dealer commissions and
 
  ·      increased recordkeeping and related costs.
 

Certain Funds may be at greater risk of harm due to frequent purchases and redemptions. For example, those Funds that invest in foreign securities may appeal to investors attempting to take advantage of time-zone arbitrage.

The Funds have adopted procedures to “fair value” foreign securities under certain circumstances, which are intended, in part, to discourage excessive trading of shares of the Funds. The Board of Directors of the Fund has also adopted policies and procedures with respect to frequent purchases and redemptions of shares of the Funds. The Funds monitor trading activity to identify and take action against abuses. While our policies and procedures are designed to identify and protect against abusive trading practices, there can be no certainty that we will identify and prevent abusive trading in all instances. If we are not able to identify such excessive trading practices, the Funds may be negatively impacted and may cause investors to suffer the harms described. When we do identify abusive trading, we will apply our policies and procedures in a fair and uniform manner. If we are not able to identify such abusive trading practices, the abuses described above may negatively impact the Funds.

Currently the Fund imposes an excessive trading fee on redemptions or exchanges of $30,000 or more of the Fund’s Class A and C shares redeemed within 30 days after they are purchased. The fee does not apply to redemptions or exchanges made pursuant to an Automatic Exchange Election or systematic Withdrawal Plan; due to a shareholder’s death or disability (as defined in the Internal Revenue Code); to satisfy minimum distribution rules imposed by the Internal Revenue Code; or where the application of the fee would cause a Fund to fail to be considered a “qualified default investment alternative” under the Employee Retirement Income Security Act of 1976, as amended, and the rules and regulations thereunder. The fee is equal to 1.00% of the total redemption or exchange amount. The fee is paid to the Fund and is intended to offset the trading costs, market impact, and other costs associated with short-term money movement in and out of the Fund.

If an intermediary, such as a retirement plan or recordkeeper, is unwilling to impose the Fund’s excessive trading fee, the Fund may waive such fee if it determines that the intermediary is able to implement other policies and procedures reasonably designed to prevent excessive trading in Fund shares. If an intermediary is unable to implement the Fund’s

Principal Funds, Inc.  FREQUENT PURCHASES AND REDEMPTIONS  29 
www.principal.com     


excessive trading policy or to implement other procedures reasonably designed to prevent excessive trading in Fund shares, the Fund may waive the application of its excessive trading policy with respect to transactions of beneficial owners underlying the intermediary’s omnibus account if, in Fund management’s opinion, the purchases and redemptions at the omnibus account level are not likely to have an adverse impact on the management of the Fund’s portfolio. The Fund will monitor net purchases and redemptions in any such omnibus account in an effort to identify trading activity that might adversely impact the management of the Fund’s portfolio and, if such excessive trading is identified, will require the intermediary to prohibit ongoing excessive trading by the underlying beneficial owner or owners whose transactions are determined to be excessive.

In addition, if the Fund deems frequent trading and redemptions to be occurring, action will be taken that may include, but is not limited to:

·      Increasing the excessive trading fee to 2%,
 
·      Increasing the excessive trading fee period from 30 days to as much as 90 days,
 
·      Applying the excessive trading fee to redemptions or exchanges of less than $30,000,
 
·      Limiting the number of permissible exchanges available to shareholders identified as “excessive traders,”
 
·      Limit exchange requests to be in writing and submitted through the United States Postal Service (in which case, requests for exchanges by fax, telephone or internet will not be accepted), and
 
·      Taking such other action as directed by the Fund.
 

The Fund has reserved the right to accept or reject, without prior written notice, any exchange requests. In some instances, an exchange may be completed prior to a determination of abusive trading. In those instances, we will reverse the exchange and return the account holdings to the positions held prior to the exchange. We will give the shareholder that requested the exchange notice in writing in this instance.

PRICING OF FUND SHARES

The Fund’s shares are bought and sold at the current share price. The share price of each class of the Fund is calculated each day the New York Stock Exchange (“NYSE”) is open (shares are not priced on the days on which the NYSE is closed for trading, generally New Year’s Day, Martin Luther King, Jr. Day, Washington’s Birthday/Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas). The share price is determined as of the close of business of the NYSE (normally 3:00 p.m. Central Time). When an order to buy or sell shares is received, the share price used to fill the order is the next price calculated after the order is received in good order by us at our transaction processing center in Canton, Massachusetts. In order for us to process your purchase order on the day it is received, we must receive the order (with complete information):

·      on a day that the NYSE is open and
 
·      prior to the close of trading on the NYSE (normally 3 p.m. Central Time).
 

Orders received after the close of the NYSE or on days that the NYSE is not open will be processed on the next day that the NYSE is open for normal trading.

If we receive an application or purchase request for a new mutual fund account or subsequent purchase into an existing account that is accompanied by a check and the application or purchase request does not contain complete information, we may hold the application (and check) for up to two business days while we attempt to obtain the necessary information. If we receive the necessary information within two business days, we will process the order using the next share price calculated. If we do not receive the information within two business days, the application and check will be returned to you.

For this Fund, the share price is calculated by:

·      taking the current market value of the total assets of the Fund
 
·      subtracting liabilities of the Fund
 
·      dividing the remainder proportionately into the classes of the Fund
 
·      subtracting the liability of each class
 
·      dividing the remainder by the total number of shares owned in that class.

·      If market quotations are not readily available for a security owned by the Fund, its fair value is determined using a policy adopted by the Directors. Fair valuation pricing is subjective and creates the possibility that the fair value determined for a security may differ materially from the value that could be realized upon the sale of the security.
 
·      The Fund’s securities may be traded on foreign securities markets that generally complete trading at various times during the day prior to the close of the NYSE. Generally, the values of foreign securities used in computing the Fund’s Net Asset Value (“NAV”) are the market quotations as of the close of the foreign market. Foreign securities and currencies are also converted to U.S. dollars using the exchange rate in effect at the close of the NYSE.
 
  Occasionally, events affecting the value of foreign securities occur when the foreign market is closed and the NYSE is open. The Fund has adopted policies and procedures to “fair value” some or all securities held by the Fund if significant events occur after the close of the market on which the foreign securities are traded but before the Fund’s NAV is calculated. Significant events can be specific to a single security or can include events that affect a particular foreign market or markets. A significant event can also include a general market movement in the U.S. securities markets. If the Manager believes that the market value of any or all of the foreign securities is materially affected by such an event, the securities will be valued, and the Fund’s NAV will be calculated, using the policy adopted by the Fund. These fair valuation procedures are intended to discourage shareholders from investing in the Fund for the purpose of engaging in market timing or arbitrage transactions.
 
  The trading of foreign securities generally or in a particular country or countries may not take place on all days the NYSE is open, or may trade on days the NYSE is closed. Thus, the value of the foreign securities held by the Fund may change on days when shareholders are unable to purchase or redeem shares.
 
·      Certain securities issued by companies in emerging market countries may have more than one quoted valuation at any point in time. These may be referred to as local price and premium price. The premium price is often a negotiated price that may not consistently represent a price at which a specific transaction can be effected. The Fund has a policy to value such securities at a price at which the Sub-Advisor expects the securities may be sold.
 

DIVIDENDS AND DISTRIBUTIONS

Dividends are based on estimates of income, expenses, and shareholder activity for the Fund. Actual income, expenses, and shareholder activity may differ from estimates; consequently, differences, if any, will be included in the calculation of subsequent dividends. The Fund pays its net investment income to shareholders of record on the business day prior to the payment date. The Fund declares dividends of its daily net investment income each day its shares are priced. On the last business day of each month the Fund will pay out its accumulated declared dividends.

Net realized capital gains, if any, are distributed annually. Generally the distribution is made on the fourth business day of December. Payments are made to shareholders of record on the business day prior to the payable date. Capital gains may be taxable at different rates, depending on the length of time that the Fund holds its assets.

Dividend and capital gains distributions will be reinvested, without a sales charge, in shares of the Fund from which the distribution is paid. However, you may authorize the distribution to be:

·      invested in shares of another Principal Funds without a sales charge (distributions of a Fund may be directed only to one receiving Fund); or
 
·      paid in cash, if the amount is $10 or more.
 

Generally, for federal income tax purposes, Fund distributions are taxable as ordinary income, except that any distributions of long-term capital gains will be taxed as such regardless of how long Fund shares have been held. Special tax rules apply to Fund distributions to Individual Retirement Accounts and other retirement plans. A tax advisor should be consulted to determine the suitability of the Fund as an investment by such a plan and the tax treatment of distributions by the Fund. A tax advisor can also provide information on the potential impact of possible foreign, state, and local taxes. A Fund’s investments in foreign securities may be subject to foreign withholding taxes. In that case, the Fund’s yield on those securities would be decreased.

To the extent that distributions the Fund pays are derived from a source other than net income (such as a return of capital), a notice will be included in your quarterly statement pursuant to Section 19(a) of the Investment Company Act

Principal Funds, Inc.  DIVIDENDS AND DISTRIBUTIONS  31 
www.principal.com     


of 1940, as amended, and Rule 19a-1 disclosing the source of such distributions. Furthermore, such notices shall be posted monthly on our web site at www.principalfunds.com. You may request a copy of all such notices, free of charge, by telephoning 1-800-222-5852. The amounts and sources of distributions included in such notices are estimates only and you should not rely upon them for purposes of reporting income taxes. The Fund will send shareholders a Form 1099-DIV for the calendar year that will tell shareholders how to report these distributions for federal income tax purposes.

NOTES:

·      A Fund’s payment of income dividends and capital gains has the effect of reducing the share price by the amount of the payment.
 
·      Distributions from a Fund, whether received in cash or reinvested in additional shares, may be subject to federal (and state) income tax.
 
·      For these reasons, buying shares of a Fund shortly before it makes a distribution may be disadvantageous to you.
 

TAX CONSIDERATIONS

Shareholders are responsible for federal income tax (and any other taxes, including state and local income taxes, if applicable) on dividends and capital gains distributions whether such dividends or distributions are paid in cash or reinvested in additional shares. Special tax rules apply to distributions to IRAs and other retirement accounts. You should consult a tax advisor to determine the suitability of the Fund as an investment by such a plan and the tax treatment of Fund distributions.

Generally, dividends paid by the Fund from interest, dividends, or net short-term capital gains will be taxed as ordinary income. Distributions properly designated by the Fund as deriving from net gains on securities held for more than one year are taxable as such (generally at a 15% tax rate), regardless of how long you have held your shares. For taxable years beginning before January 1, 2009, distributions of investment income properly designated by the Fund as derived from “qualified dividend income” will be taxed at the rates applicable to long-term capital gains.

A dividend or distribution made shortly after the purchase of shares of the Fund by a shareholder, although in effect a return of capital to that shareholder, would be taxable to that shareholder as described above.

Because of tax law requirements, you must provide the Fund with an accurate and certified taxpayer identification number (for individuals, generally a Social Security number) to avoid “back-up” withholding, which is currently imposed at a rate of 28%.

Early in each calendar year, each Fund will notify you of the amount and tax status of distributions paid to you for the preceding year.

Any gain resulting from the sale, redemption, or exchange of your shares will generally also be subject to tax. You should consult your tax advisor for more information on your own tax situation, including possible foreign, state, and local taxes.

Investments by the Fund in foreign securities may be subject to foreign withholding taxes. In that case, the Fund’s yield on those securities would be decreased. Shareholders of the Funds that invest in foreign securities may be entitled to claim a credit or deduction with respect to foreign taxes. In addition, the Fund’s investments in foreign securities or foreign currencies may increase or accelerate the Fund’s recognition of ordinary income and may affect the timing or amount of the Fund’s distributions.

Investments by the Fund in certain debt instruments or derivatives may cause the Fund to recognize taxable income in excess of the cash generated by such instruments. As a result, the Fund could be required at times to liquidate other investments in order to satisfy its distribution requirements under the Code. The Fund’s use of derivatives will also affect the amount, timing, and character of the Fund’s distributions.

DISTRIBUTION PLANS AND INTERMEDIARY COMPENSATION

The Fund has adopted a 12b-1 Plan for Class A and Class C shares. Under the 12b-1 Plans, the Fund may make payments from its assets attributable to the particular share class to the Fund’s Distributor for distribution-related expenses and for providing services to shareholders of that share class. Payments under the 12b-1 plans will not automatically terminate for funds that are closed to new investors or to additional purchases by existing shareholders. The fund Board will determine whether to terminate, modify, or leave unchanged the 12b-1 plan at the time the Board directs the implementation of the closure of the fund. Because Rule 12b-1 fees are ongoing fees, over time they will increase the cost of an investment in the Funds and may cost more than paying other types of sales charges.

The Distributor for Principal Investors Fund is Principal Funds Distributor, a wholly owned subsidiary of PFG. The term “Distributor” as used in this section refers to Principal Funds Distributor.

The maximum annual Rule 12b-1 distribution and/or service fee (as a percentage of average daily net assets) for each of the above classes of the Funds are set forth below:

Share Class  Maximum Annualized Rule 12b-1 Fee 
 Class A  0.25% 
 Class C  1.00% 

Service Fees. The Distributor may pay service fees to dealers and other intermediaries at the annual rate of 0.25% of the average daily net assets of such shares for which they are the dealers of record. Generally, to receive service fees from the Distributor, dealers or other intermediaries must be the dealer of record for shares with average daily net assets of at least $100,000. Generally, Class A shares must be held for three months before these fees are paid. In the case of Class C shares, generally these fees are not paid until such shares have been held for twelve months.

Distribution Fees. The proceeds from the Rule 12b-1 distribution fees paid by Class C shareholders, together with any applicable sales charge, are paid to the Distributor. The Distributor generally uses distribution fees to finance any activity that is primarily intended to result in the sale of shares. Examples of such expenses include compensation to salespeople, including ongoing commissions payments for class C shares, and selected dealers (including financing the commission paid to the dealer at the time of the sale), printing of prospectuses and statements of additional information and reports for other than existing shareholders, and preparing and conducting sales seminars.

Payments to Investment Representatives and Their Firms. Financial intermediaries market and sell shares of the Fund. These financial intermediaries receive compensation from the Distributor and its affiliates for selling shares of the Fund and/or providing services to the Fund’s shareholders. Financial intermediaries may include, among others, broker-dealers, registered investment advisors, banks, trust companies, pension plan consultants, retirement plan administrators, and insurance companies. Investment Representatives who deal with investors on an individual basis are typically associated with a financial intermediary. The Distributor and its affiliates may fund this compensation from various sources, including any sales charge and/or Rule 12b-1 Plan fee that the shareholder or the Funds pay to the Distributor. Individual Investment Representatives may receive some or all of the amounts paid to the financial intermediary with which he or she is associated.

Commissions, Finders’ Fees, and Ongoing Payments. In the case of Class A shares, all or a portion of the initial sales charge that you pay may be paid by the Distributor to financial intermediaries selling Class A shares. The Distributor may pay these financial intermediaries a finders’ fee of up to 1.00% on purchases of $1,000,000 or more, excluding purchases by qualified retirement plans in omnibus accounts which are not subject to initial sales charges. See immediately below for details. See “Choosing a Share Class” for more details. Additionally, the Distributor

Principal Funds, Inc.  DISTRIBUTION PLANS AND INTERMEDIARY COMPENSATION  33 
www.principal.com     


generally makes ongoing payments to your financial intermediary for services provided to you at an annual rate of up to 0.25% of average net assets attributable to your investment in Class A shares.

The Distributor may pay financial intermediaries a finders’ fee on initial investments by qualified retirement plans in omnibus accounts, which are not subject to initial sales charges, provided the selling intermediary notifies the Distributor within 90 days of the initial purchase that the transaction is eligible for the payment of a finders’ fee. The finders’ fee on initial investments of $500,000 to $3,000,000 may be in an amount of up to 1% of the initial purchase. Initial investments by qualified retirement plans in omnibus accounts over $3,000,000 may be eligible for a finders’ fee in accordance with the schedule determined by the Distributor but shall not be paid a fee greater than 1.00% of the initial amount. Initial investments include transfers, rollovers and other lump sum purchases, excluding ongoing systematic investments, made within 90 days of the initial funding of the account. The dealer shall, upon request by the Distributor provided within 90 days of the triggering event, refund the finders’ fee to the Distributor if assets are liquidated within 12 months of the initial purchase or trading restrictions are placed on the account in accordance with the Funds’ frequent trading policy.

In the case of Class C shares, the Distributor will pay, at the time of your purchase, a commission to your financial intermediary in an amount equal to 1.00% of your investment. Additionally, the Distributor generally makes ongoing payments to your financial intermediary for distribution and services provided to you at an annual rate of 1.00% of average net assets attributable to your investment in Class C shares.

Other Payments to Intermediaries. In addition to the commissions paid at the time of sale, ongoing payments, and the reimbursement of costs associated with education, training and marketing efforts, conferences, seminars, due diligence trip expenses, ticket charges, and other general marketing expenses, some or all of which may be paid to financial intermediaries (and, in turn, to your Investment Representative), the Distributor and its affiliates, at their expense, currently provide additional payments to financial intermediaries that sell shares of the Funds for distribution services. Although payments made to each qualifying financial intermediary in any given year may vary, such payments will generally not exceed (a) 0.25% of the current year’s sales of Fund shares by that financial intermediary and/or (b) 0.25% of average daily net assets of Fund shares serviced by that financial intermediary over the year.

A number of factors are considered in determining the amount of these additional payments, including each financial intermediary’s Fund sales, assets, and redemption rates as well as the willingness and ability of the financial intermediary to give the Distributor access to its Investment Representatives for educational and marketing purposes. In some cases, financial intermediaries will include the Fund on a “preferred list.” The Distributor’s goals include making the Investment Representatives who interact with current and prospective investors and shareholders more knowledgeable about the Fund so that they can provide suitable information and advice about the Fund and related investor services.

Additionally, the Distributor may provide payments to reimburse directly or indirectly the costs incurred by these financial intermediaries and their associated Investment Representatives in connection with educational seminars and training and marketing efforts related to the Fund for the firms’ employees and/or their clients and potential clients. The costs and expenses associated with these efforts may include travel, lodging, entertainment, and meals. The Distributor may also provide payment or reimbursement for expenses associated with qualifying dealers’ conferences, transactions (“ticket”) charges, and general marketing expenses.

In connection with the purchase by Principal Management Corporation (“Principal”) of WM Advisors, Inc. (“WM Advisors”), the investment advisor to the WM Funds, and WM Advisors’ two subsidiaries, WM Funds Distributor, Inc. and WM Shareholder Services, Inc. (the “Transaction”), New American Capital, Inc. and its parent company Washington Mutual, Inc. (“WaMu”) have agreed to make certain contingent payments to Principal with respect to each of the first four years following the closing of the Transaction. Such payments must be made if aggregate management fee revenues to Principal and its affiliates from assets under management in funds and other financial products advised by Principal and its affiliates (including the fund covered by this prospectus) (collectively, the “Principal Products”) sold through WaMu and its affiliates (including WaMu Investments, a broker-dealer subsidiary of WaMu) fall below certain specified targets during any such year. This could result in up to $30 million being paid by WaMu or New American Capital, Inc. to Principal with respect to each of those four years following the closing of the Transaction. As

34  DISTRIBUTION PLANS AND INTERMEDIARY COMPENSATION  Principal Funds, Inc. 
    1-800-222-5852 


a result, WaMu Investments (and/or it affiliates) will have an additional incentive to sell Principal Products following the closing of the Transaction.

If one mutual fund sponsor makes greater distribution assistance payments than another, your Investment Representative and his or her financial intermediary may have an incentive to recommend one fund complex over another. Similarly, if your Investment Representative or his or her financial intermediary receives more distribution assistance for one share class versus another, then they may have an incentive to recommend that share class.

Please speak with your Investment Representative to learn more about the total amounts paid to your Investment Representative and his or her financial intermediary by the Funds, the Distributor and its affiliates, and by sponsors of other mutual funds he or she may recommend to you. You should also carefully review disclosures made by your Investment Representative at the time of purchase.

As of the date of the prospectus, the Distributor anticipates that the firms that will receive additional payments for distribution of the Funds (other than commissions paid at the time of sale, ongoing payments, and the reimbursement of cost associated with education, training and marketing efforts, conferences, ticket charges, and other general marketing expenses) include:

Although a Fund may use brokers who sell shares of the Fund to effect portfolio transactions, the sale of shares is not considered as a factor by the Fund’s Sub-Advisors when selecting brokers to effect portfolio transactions.

Your financial intermediary may charge fees and commissions, including processing fees, in addition to those described in this prospectus. The amount and applicability of any such fee is determined and disclosed separately by the financial intermediary. You should ask your Investment Representative for information about any fees and/or commissions that are charged.

Transfer Agency and Retirement Plan Services. Principal Shareholder Services, Inc. acts as the transfer agent for the Fund. As such, it registers the transfer, issuance, and redemption of fund shares and disburses dividends and other distributions to fund shareholders.

Many fund shares are owned by financial intermediaries for the benefit of their customers. In those cases, the fund often does not maintain an account for these investors. Thus, some or all of the transfer agency functions for these accounts are performed by the financial intermediaries. The transfer agent may pay these financial intermediaries fees for sub-transfer agency and/or related recordkeeping services. Retirement plans may also hold fund shares in the name of the plan, rather than the participant. Plan recordkeepers, who may have affiliated financial intermediaries that sell shares of the fund, may be paid additional amounts. In addition, financial intermediaries may be affiliates of entities that receive compensation from the Distributor for maintaining retirement plan “platforms” that facilitate trading by affiliated and non-affiliated financial intermediaries and recordkeeping for retirement plans.

The amounts paid to financial intermediaries and plan recordkeepers for sub-transfer agency and recordkeeping services, and their related service requirements may vary across fund groups and share classes. This may create an incentive for financial intermediaries and their Investment Representatives to recommend one fund complex over another or one class of shares over another.

FUND ACCOUNT INFORMATION

Procedures for Opening an Account

To help the government fight the funding of terrorism and money laundering activities, Federal law requires financial institutions to obtain, verify, and record information that identifies each person who opens an account. When you open an account, we will ask for your name, address, date of birth, and other information that will allow us to verify your identity. We may also ask to see your driver’s license or other identifying documents.

If concerns arise with verification of your identification, no transactions, other than redemptions, will be permitted while we attempt to reconcile the concerns. If we are unable to verify your identity on a timely basis, we may close your account or take such other action as we deem appropriate.

Accounts with foreign addresses cannot be established. If an existing shareholder with a U.S. address moves to a foreign location and updates the address on the shareholder’s account, we are unable to process any purchases or exchanges on that account.

Orders Placed by Intermediaries

Principal Funds may have an agreement with your intermediary, such as a broker-dealer, third party administrator or trust company, that permits the intermediary to accept orders on behalf of the Fund until 3 p.m. Central Time. The agreement may include authorization for your intermediary to designate other intermediaries (“sub-designees”) to accept orders on behalf of the Fund on the same terms that apply to the intermediary. In such cases, if your intermediary or a sub-designee receives your order in correct form by 3 p.m. Central Time, transmits it to the Fund and

36  FUND ACCOUNT INFORMATION  Principal Funds, Inc. 
    1-800-222-5852 


pays for it in accordance with the agreement, the Fund will price the order at the next net asset value per share it computes after your intermediary or sub-designee received your order. Note: The time at which the Fund prices orders and the time until which the Fund or your intermediary or sub-designee will accept orders may change in the case of an emergency or if the NYSE closes at a time other than 3 p.m. Central Time.

Statements

You will receive quarterly statements for the Fund you own. The quarterly statements provide the number and value of shares you own, transactions during the period, dividends declared or paid, and other information. The year-end statement includes information for all transactions that took place during the year. Please review your statement as soon as you receive it. Keep your statements as you may need them for tax reporting purposes.

Generally, each time you buy, sell, or exchange shares in Principal Funds, you will receive a confirmation in the mail shortly thereafter. It summarizes all the key information – what you bought or sold, the amount of the transaction, and other important information.

Certain purchases and sales are only included on your quarterly statement. These include accounts:

·      when the only activity during the quarter:
 
  ·      is purchase of shares from reinvested dividends and/or capital gains,
 
  ·      are purchases under an Automatic Investment Plan,
 
  ·      are sales under a systematic withdrawal plan, or
 
  ·      are purchases or sales under an automatic exchange election;
 
·      used to fund certain individual retirement or individual pension plans; or
 
·      established under a payroll deduction plan.
 

If you need information about your account(s) at other times, you may call us at 1-800-222-5852 or access your account on the internet.

Signature Guarantees

Certain transactions require a Medallion Signature Guarantee, unless specifically waived by the Fund’s transfer agent. If required, the signature(s) must be guaranteed by a commercial bank, trust company, credit union, savings and loan, national securities exchange member, or brokerage firm which participates in a Medallion program recognized by the Securities Transfer Association. A signature guarantee by a notary public or savings bank is not acceptable. Signature guarantees are required:

·      if you sell more than $100,000 (in the aggregate) from the Fund;
 
·      if a sales proceeds check is payable to other than the account shareholder(s), Principal Life, or Principal Bank;
 
·      to change ownership of an account;
 
·      to add wire or ACH redemption privileges to a U.S. bank account not previously authorized;
 
·      to change bank account information designated under an existing telephone withdrawal plan;
 
·      to exchange or transfer among accounts with different ownership; and
 
·      to have a sales proceeds check mailed to an address other than the address on the account or to the address on the account if it has been changed within the preceding 30 days.
 

Special Plans

The Fund reserves the right to amend or terminate the special plans described in this prospectus. Such plans include automatic investment, systematic withdrawal, waiver of Fund minimums for certain accounts and waiver or reduction of the sales charge or contingent deferred sales charge for certain purchasers. You will be notified of any such action to the extent required by law.

Minimum Account Balance

Generally, the Fund does not have a minimum required balance. Because of the disproportional high cost of maintaining small accounts, the Fund reserves the right to set a minimum and sell all shares in an account with a value of $1,000 or less. The sales proceeds would then be mailed to you. These involuntary sales will not be triggered just by market conditions. If the Fund exercises this right, you will be notified that the redemption is going to be made. You will have 30 days to make an additional investment and bring your account up to the required minimum. The Fund reserves the right to increase the required minimum.

Telephone and Internet Instructions

The Fund reserves the right to refuse telephone and/or internet instructions. You are liable for a loss resulting from a fraudulent telephone or internet instruction that we reasonably believe is genuine. We use reasonable procedures to assure instructions are genuine. If the procedures are not followed, we may be liable for loss due to unauthorized or fraudulent transactions. The procedures include: recording all telephone instructions, requiring the use of a password (Personal Identification Number) for internet instructions, requesting personal identification information (name, address, phone number, social security number, birth date, security phrase, etc.), and sending written confirmation to the shareholder’s address of record.

If you elect telephone privileges, instructions regarding your account(s) may be given to us via the telephone or internet. Your instructions:

·      may be given by calling us at 1-800-222-5852 between 7 a.m. and 7 p.m. Central Time on any day that the NYSE is open;
 
·      may be given by accessing our website (for security purposes you need a user name and password to use any of the internet services, including viewing your account information on-line. If you don’t have a user name or password, you may obtain one at our website). Note: only certain transactions are available on-line.
 
·      must be received in good order at our transaction processing center in Canton, Massachusetts, in their entirety, by us before the close of the NYSE (generally 3:00 p.m. Central Time) to be effective the day of your request;
 
·      are effective the next business day if not received until after the close of the NYSE; and
 
·      may be given to your Investment Representative who will in turn contact us with your instructions (Princor registered representatives may only convey your specific instructions to the Fund’s transfer agent; they may not be granted investment discretion).
 
NOTE:  Instructions received from one owner are binding on all owners. In the case of an account owned by a 
  corporation or trust, instructions received from an authorized person are binding on the corporation/trust 
  unless we have a written notification requiring that written instructions be executed by more than one 
  authorized person. 

Householding

To avoid sending duplicate copies of materials to households, only one copy of each prospectus, annual and semi-annual report to shareholders will be mailed to shareholders having the same last name and address on the Fund’s records. The consolidation of these mailings, called householding, benefits Principal Funds through reduced mailing expense. If you want to receive multiple copies of these materials, you may call Principal Funds at 1-800-222-5852. You may notify Principal Funds in writing.

APPENDIX A

SUMMARY OF PRINCIPAL RISKS

The value of your investment in a Fund changes with the value of the investments held by that Fund. Many factors affect that value, and it is possible that you may lose money by investing in the Fund. Factors that may adversely affect the Fund as a whole are called “principal risks.” The principal risks of investing in the Fund are stated above as to the Fund in its description. Each of these risks is summarized below. Additional information about the Funds, their investments, and the related risks is located under “Certain Investment Strategies and Related Risks” and in the Statement of Additional Information.

Active Trading Risk

A fund that actively trades portfolio securities in an attempt to achieve its investment objective may have high portfolio turnover rates that may increase the fund’s brokerage costs, accelerate the realization of taxable gains, and adversely impact fund performance.

Derivatives Risk

Derivatives are investments whose values depend on or are derived from other securities or indexes. A fund’s use of certain derivative instruments (such as options, futures, and swaps) could produce disproportionate gains or losses. Derivatives are generally considered more risky than direct investments and, in a down market, could become harder to value or sell at a fair price.

Emerging Market Risk

Investments in emerging market countries involve special risks. Certain emerging market countries have historically experienced, and may continue to experience, certain economic problems. These may include: high rates of inflation, high interest rates, exchange rate fluctuations, large amounts of debt, balance of payments and trade difficulties, and extreme poverty and unemployment.

Equity Securities Risk

Equity securities include common, preferred, and convertible preferred stocks and securities the values of which are tied to the price of stocks, such as rights, warrants, and convertible debt securities. Common and preferred stocks represent equity ownership in a company. Stock markets are volatile, and the price of equity securities (and their equivalents) will fluctuate. The value of equity securities purchased by a fund could decline if the financial condition of the companies in which the fund invests decline or if overall market and economic conditions deteriorate.

Exchange Rate Risk

Because foreign securities are generally denominated in foreign currencies, the value of the net assets of a fund as measured in U.S. dollars will be affected by changes in exchange rates. To protect against future uncertainties in foreign currency exchange rates, the funds are authorized to enter into certain foreign currency exchange transactions. In addition, the funds’ foreign investments may be less liquid and their price more volatile than comparable investments in U.S. securities. Settlement periods may be longer for foreign securities and portfolio liquidity may be affected.

Fixed-Income Securities Risk

Fixed-income securities are generally subject to two principal types of risks: interest rate risk and credit quality risk.

Interest Rate Risk. Fixed-income securities are affected by changes in interest rates. When interest rates decline, the market value of the fixed-income securities generally can be expected to rise. Conversely, when interest rates rise, the market value of fixed-income securities generally can be expected to decline.

Credit Quality Risk. Fixed-income securities are subject to the risk that the issuer of the security will not repay all or a portion of the principal borrowed and will not make all interest payments. If the credit quality of a fixed income security deteriorates after a fund has purchased the security, the market value of the security may decrease and lead to a decrease in the value of the fund’s investments. Lower quality and longer maturity bonds will be subject to greater

Principal Funds, Inc.  APPENDIX A  39 
www.principal.com     


credit risk and price fluctuations than higher quality and shorter maturity bonds. Bonds held by a fund may be affected by unfavorable political, economic, or government developments that could affect the repayment of principal or the payment of interest.

Foreign Securities Risk

Foreign securities carry risks that are not generally found in securities of U.S. companies. These risks include the loss of value as a result of political instability and financial and economic events in foreign countries. In addition, nationalization, expropriation or confiscatory taxation, and foreign exchange restrictions could adversely affect a fund’s investments in a foreign country. Foreign securities may be subject to less stringent reporting, accounting, and disclosure standards than are required of U.S. companies, and foreign countries may also have problems associated with and causing delays in the settlement of sales.

High Yield Securities Risk

Fixed-income securities that are not investment grade are commonly referred to as high yield securities or “junk bonds.” While these securities generally provide greater income potential than investments in higher rated fixed-income securities, there is a greater risk that principal and interest payments will not be made. Issuers of these securities may even go into default or become bankrupt. High yield securities generally involve greater price volatility and may be less liquid than higher rated fixed-income securities. High yield securities are considered speculative by the major credit rating agencies.

Portfolio Duration Risk

Portfolio duration is a measure of the expected life of a fixed-income security that is used to determine the sensitivity of a security’s price to changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Real Estate Securities Risk

Real estate investment trusts (“REITs”) or other real estate-related securities are subject to the risks associated with direct ownership of real estate, including declines in the value of real estate, risks related to general and local economic conditions, increases in property taxes and operating expenses, changes in zoning laws, changes in interest rates, and liabilities resulting from environmental problems. Equity and mortgage REITs are dependent on management skills and generally are not diversified. Equity REITs are affected by the changes in the value of the properties owned by the trust. Mortgage REITs are affected by the quality of the credit extended. Both equity and mortgage REITs:

·      may not be diversified with regard to the types of tenants (thus subject to business developments of the tenant(s));
 
·      may not be diversified with regard to the geographic locations of the properties (thus subject to regional economic developments);
 
·      are subject to cash flow dependency and defaults by borrowers; and
 
·      could fail to qualify for tax-free pass-through of income under the Internal Revenue Code.
 

Securities Lending Risk

The principal risk of securities lending is that the financial institution that borrows securities from the Fund could go bankrupt or otherwise default on its commitment under the securities lending agreement and the Fund might not be able to recover the loaned securities or their value.

Value Stock Risk

A fund’s investments in value stocks carry the risk that the market will not recognize a security’s intrinsic value for a long time or that a stock judged to be undervalued may actually be appropriately priced. A value stock may not increase in price if other investors fail to recognize the company’s value and bid up the price or invest in markets favoring faster growing companies. A fund’s strategy of investing in value stocks also carries the risk that in certain markets value stocks will underperform growth stocks.

APPENDIX B

Description of Bond Ratings:

Moody’s Investors Service, Inc. Rating Definitions:

Long-Term Obligation Ratings

Moody’s long-term obligation ratings are opinions of the relative credit risk of fixed-income obligations with an original maturity of one year or more. They address the possibility that a financial obligation will not be honored as promised. Such ratings reflect both the likelihood of default and any financial loss suffered in the event of default.

Aaa:  Obligations rated Aaa are judged to be of the highest quality, with minimal credit risk. 
Aa:  Obligations rated Aa are judged to be of high quality and are subject to very low credit risk. 
A:  Obligations rated A are considered upper-medium grade and are subject to low credit risk. 
Baa:  Obligations rated Baa are subject to moderate credit risk. They are considered medium-grade and as such 
  may possess certain speculative characteristics. 
Ba:  Obligations rated Ba are judged to have speculative elements and are subject to substantial credit risk. 
B:  Obligations rated B are considered speculative and are subject to high credit risk. 
Caa:  Obligations rated Caa are judged to be of poor standing and are subject to very high credit risk. 
Ca:  Obligations rated Ca are highly speculative and are likely in, or very near, default, with some prospect of 
  recovery of principal and interest. 
C:  Obligations rated C are the lowest rated class of bonds and are typically in default, with little prospect for 
  recovery of principal or interest. 

NOTE: Moody’s appends numerical modifiers, 1, 2, and 3 to each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category, the modifier 2 indicates a mid-range ranking, and the modifier 3 indicates a ranking in the lower end of that generate rating category.

SHORT-TERM NOTES: The four ratings of Moody’s for short-term notes are MIG 1, MIG 2, MIG 3, and MIG 4. MIG 1 denotes “best quality, enjoying strong protection from established cash flows.” MIG 2 denotes “high quality” with “ample margins of protection.” MIG 3 notes are of “favorable quality...but lacking the undeniable strength of the

Principal Funds, Inc.  APPENDIX B  41 
www.principal.com     


preceding grades.” MIG 4 notes are of “adequate quality, carrying specific risk for having protection...and not distinctly or predominantly speculative.”

Description of Moody’s Commercial Paper Ratings:

Moody’s Commercial Paper ratings are opinions of the ability to repay punctually promissory obligations not having an original maturity in excess of nine months. Moody’s employs the following three designations, all judged to be investment grade, to indicate the relative repayment capacity of rated issuers:

Issuers rated Prime-1 (or related supporting institutions) have a superior capacity for repayment of short-term promissory obligations.

Issuers rated Prime-2 (or related supporting institutions) have a strong capacity for repayment of short-term promissory obligations.

Issuers rated Prime-3 (or related supporting institutions) have an acceptable capacity for repayment of short-term promissory obligations.

Issuers rated Not Prime do not fall within any of the Prime rating categories.

Description of Standard & Poor’s Corporation’s Debt Ratings:

A Standard & Poor’s debt rating is a current assessment of the creditworthiness of an obligor with respect to a specific obligation. This assessment may take into consideration obligors such as guarantors, insurers, or lessees.

The debt rating is not a recommendation to purchase, sell or hold a security, inasmuch as it does not comment as to market price or suitability for a particular investor.

The ratings are based on current information furnished by the issuer or obtained by Standard & Poor’s from other sources Standard & Poor’s considers reliable. Standard & Poor’s does not perform an audit in connection with any rating and may, on occasion, rely on unaudited financial information. The ratings may be changed, suspended, or withdrawn as a result of changes in, or unavailability of, such information, or for other circumstances.

The ratings are based, in varying degrees, on the following considerations:

I.  Likelihood of default – capacity and willingness of the obligor as to the timely payment of interest and 
  repayment of principal in accordance with the terms of the obligation; 
 
II.  Nature of and provisions of the obligation; 
 
III.  Protection afforded by, and relative position of, the obligation in the event of bankruptcy, reorganization, or 
  other arrangement under the laws of bankruptcy and other laws affecting creditor’s rights. 
 
AAA:  Debt rated “AAA” has the highest rating assigned by Standard & Poor’s. Capacity to pay interest and repay 
  principal is extremely strong. 

42  APPENDIX B  Principal Funds, Inc. 
    1-800-222-5852 


 
 AA:         Debt rated “AA” has a very strong capacity to pay interest and repay principal and differs from the highest- 
         rated issues only in small degree. 
 
 
 
 A:         Debt rated “A” has a strong capacity to pay interest and repay principal although they are somewhat more 
         susceptible to the adverse effects of changes in circumstances and economic conditions than debt in 
         higher-rated categories. 
 
 
 
 BBB:         Debt rated “BBB” is regarded as having an adequate capacity to pay interest and repay principal. Whereas 
         it normally exhibits adequate protection parameters, adverse economic conditions or changing circum- 
         stances are more likely to lead to a weakened capacity to pay interest and repay principal for debt in this 
         category than for debt in higher-rated categories. 
 
 
BB, B, CCC, CC:         Debt rated “BB,” “B,” “CCC,” and “CC” is regarded, on balance, as predominantly speculative with 
                              respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. 
                              “BB” indicates the lowest degree of speculation and “CC” the highest degree of speculation. While 
                              such debt will likely have some quality and protective characteristics, these are outweighed by large 
                              uncertainties or major risk exposures to adverse conditions. 
 
 C:  The rating “C” is reserved for income bonds on which no interest is being paid. 
 
 
 
 D:  Debt rated “D” is in default, and payment of interest and/or repayment of principal is in arrears. 

Plus (+) or Minus (-): The ratings from “AA” to “B” may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

Provisional Ratings: The letter “p” indicates that the rating is provisional. A provisional rating assumes the successful completion of the project being financed by the bonds being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, however, while addressing credit quality subsequent to completion of the project, makes no comment on the likelihood of, or the risk of default upon failure of, such completion. The investor should exercise his own judgment with respect to such likelihood and risk.

NR:  Indicates that no rating has been requested, that there is insufficient information on which to base a rating or 
  that Standard & Poor’s does not rate a particular type of obligation as a matter of policy. 

Standard & Poor’s, Commercial Paper Ratings

A Standard & Poor’s Commercial Paper Rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days. Ratings are graded into four categories, ranging from “A” for the highest quality obligations to “D” for the lowest. Ratings are applicable to both taxable and tax-exempt commercial paper. The four categories are as follows:

A:  Issues assigned the highest rating are regarded as having the greatest capacity for timely payment. Issues 
  in this category are delineated with the numbers 1, 2, and 3 to indicate the relative degree of safety. 

Principal Funds, Inc.  APPENDIX B  43 
www.principal.com     


A-1:  This designation indicates that the degree of safety regarding timely payment is either overwhelming or 
  very strong. Issues that possess overwhelming safety characteristics will be given a “+” designation. 
 
A-2:  Capacity for timely payment on issues with this designation is strong. However, the relative degree of 
  safety is not as high as for issues designated “A-1.” 
 
A-3:  Issues carrying this designation have a satisfactory capacity for timely payment. They are, however, some- 
  what more vulnerable to the adverse effects of changes in circumstances than obligations carrying the 
  highest designations. 
 
B:  Issues rated “B” are regarded as having only an adequate capacity for timely payment. However, such 
  capacity may be damaged by changing conditions or short-term adversities. 
 
C:  This rating is assigned to short-term debt obligations with a doubtful capacity for payment. 
 
D:  This rating indicates that the issue is either in default or is expected to be in default upon maturity. 

The Commercial Paper Rating is not a recommendation to purchase or sell a security. The ratings are based on current information furnished to Standard & Poor’s by the issuer and obtained by Standard & Poor’s from other sources it considers reliable. The ratings may be changed, suspended, or withdrawn as a result of changes in or unavailability of, such information.

Standard & Poor’s rates notes with a maturity of less than three years as follows:

SP-1:  A very strong, or strong, capacity to pay principal and interest. Issues that possess overwhelming safety 
 

characteristics will be given a “+” designation. 

 

SP-2: 

 

A satisfactory capacity to pay principal and interest. 

 

SP-3:  A speculative capacity to pay principal and interest.

  1-800-222-5852 


GLOBAL DIVERSIFIED INCOME FUND 
 
Sub-Advisor(s): Principal Global Investors, LLC, ("PGI”), Principal Real Estate Investors, LLC (“Principal-REI"), and   
  Spectrum Asset Management, Inc. ("Spectrum”) 
 
Objective:  The Fund seeks consistent cash income through a diversified, yield-focused investment strategy. 
 
Investor Profile:    The Fund may be an appropriate investment for investors seeking high cash returns, who are willing
  to accept the risk associated with investing in equities and below-investment-grade fixed income 
  securities. 

Main Strategies and Risks

The Fund will invest a majority of its assets in fixed income asset classes, such as high yield bonds, preferred stocks, and emerging market debt securities, to provide incremental yields over a portfolio of government securities. In addition, the Fund will invest in equity securities of global companies principally engaged in the real estate industry and value equities of global companies to provide dividend yields and diversify fixed income-related risks in the Fund. The Fund seeks to provide yield by having each sub-advisor focus on those securities offering the best risk-adjusted yields within their respective asset class.

Approximately 35% of the Fund's assets will be invested in high yield and other income-producing securities including corporate bonds, corporate loan participations and assignments, convertible securities, credit default swaps, and securities of companies in bankruptcy proceedings or otherwise in the process of debt restructuring. The "high yield" securities in which the Fund invests are commonly known as "junk bonds" which are rated Ba or lower by Moody's Investor Service, Inc. ("Moody's") or BB or lower by Standard & Poor's Rating Service ("S&P"). These securities offer a higher yield than other, higher rated securities, but they carry a greater degree of risk and are considered speculative with respect to the issuer's ability to pay interest and to repay principal. It is expected that this portion of the Fund will have a weighted average quality rating of Ba3 as measured by Moody's or BB- by S&P. The average duration will be 2-3 years. PGI will manage this portion of the Fund.

Approximately 20% of the Fund's assets will be invested in equity securities of global companies principally engaged in the real estate industry ("real estate companies"). A real estate company has at least 50% of its assets, income or profits derived from products or services related to the real estate industry. Real estate companies include real estate investment trusts (“REITs”), REIT-like entities, and companies with substantial real estate holdings such as paper, lumber, hotel and entertainment companies as well as building supply manufacturers, mortgage lenders, and mortgage servicing companies. This portion of the Fund may invest in smaller capitalization companies. Principal-REI will manage this portion of the Fund.

Approximately 20% of the Fund's assets will be invested in preferred securities of U.S. companies primarily rated BBB or higher by S&P or Baa by Moody's or, if unrated, of comparable quality in the opinion of the Sub-Advisor. This portion of the Fund focuses primarily on the financial services, REITs, and utility industries. The rest of this portion of the Fund's assets may be invested in common stocks, debt securities, credit default swaps, and securities issued or guaranteed by the U.S. government or its agencies or instrumentalities. Spectrum will manage this portion of the Fund.

Approximately 15% of the Fund's assets will be invested in a diversified portfolio of value equity securities of companies located or operating in developed countries (including the United States) and emerging markets of the world to provide dividend yields. The equity securities will ordinarily be traded on a recognized foreign securities exchange or traded in a foreign over-the-counter market in the country where the issuer is principally based, but may also be traded in other countries including the United States. PGI will manage this portion of the Fund.

Approximately 10% of the Fund's assets will be invested in a diversified portfolio of bond issues issued primarily by governments, their agencies, local authorities and instrumentalities and corporate entities domiciled in or exercising the predominant part of their economic activities in emerging markets in Europe, Latin America, Asia, and the Middle East. The target duration for the portfolio will be 2-3 years. The targeted credit quality range will be Baa2 to B3 as measured by Moody's or BBB to B- by S&P. Securities denominated in local currency will be limited to 50% of the

Principal Funds, Inc.  RISK/RETURN SUMMARY  5 
www.principal.com     


portfolio in aggregate, and, typically, non-dollar currency exposure will not be hedged. PGI will manage this portion of the Fund.

Among the principal risks (as defined in Appendix A) of investing in the Fund are:

• High Yield Securities Risk  • Real Estate Securities Risk  • Equity Securities Risk 
• Active Trading Risk  • Value Stock Risk  • Exchange Rate Risk 
• Fixed-Income Risk  • Portfolio Duration Risk  • Foreign Securities Risk 
• Emerging Market Risk  • Derivatives Risk  • Securities Lending Risk 

The Fund is actively managed primarily against the Lehman Brothers U.S. Corporate High Yield - 2% Issuer Capped Index. Other indices are shown.

The Lehman Brothers U.S. Corporate High Yield - 2% Issuer Capped Index is an unmanaged index comprised of fixed rate, non-investment grade debt securities that are dollar denominated. The index limits the maximum exposure to any one issuer to 2%.

The Morgan Stanley Capital International (MSCI) World Value Index is a free float-adjusted market capitalization index that represents the value segment in global developed market equity performance.

The FTSE-EPRA (European Public Real Estate Association)-NAREIT (National Association of Real Estate Investment Trusts) Global Real Estate Securities Index is designed to track the performance of real estate companies and REITS worldwide.

The Merrill Lynch Fixed Rate Preferred Securities Index tracks the performance of fixed rate US dollar denominated preferred securities issued in the US domestic market.

The JPMorgan Emerging Markets Bond Index (EMBI) Global includes U.S. dollar denominated Brady bonds, Eurobonds, and traded loans issued by sovereign and quasi-sovereign entities. The EMBI Global is a market-capitalization-weighted index.

Morningstar World Allocation Category. World-allocation portfolios seek to provide both capital appreciation and income by investing in three major areas: stocks, bonds, and cash. While these portfolios do explore the whole world, most of them focus on the U.S., Canada, Japan, and the larger markets in Europe.

This Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The expenses shown below would not change, however, if you continued to hold all of your shares at the end of the periods shown. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your cost would be:

THE COSTS OF INVESTING

Fees and Expenses of the Fund

Fund shares are sold without a front-end sales charge and do not have a contingent deferred sales charge. There is no sales charge on shares of the Fund purchased with reinvested dividends or other distributions.

In addition to the ongoing fees listed below, the Institutional Class of the Fund may pay a portion of investment related expenses (e.g., interest on reverse repurchase agreements) that are allocated to all classes of the Fund.

Ongoing Fees

Ongoing Fees reduce the value of each share. Because they are ongoing, they increase the cost of investing in the Fund.

The Fund pays ongoing fees to the Manager and others who provide services to the Fund. These fees include:

·      Management Fee – Through the Management Agreement with the Fund, Principal has agreed to provide investment advisory services and corporate administrative services to the Fund.
 
·      Other Expenses – A portion of expenses that are allocated to all classes of the Fund.
 

Princor and PFD are the Fund’s principal underwriters for Institutional Class shares. They may, from time-to-time, at their expense, pay a bonus or other consideration or incentive to dealers who have sold or may sell significant amounts of shares. Any such bonus or incentive program will not change the price investors pay for the purchase of the Fund’s shares or the amount that the Fund receives as the proceeds from such sales. In addition, the Distributors or their affiliates may provide financial support to dealers that sell shares of the Fund. This support is based primarily on the amount of sales of fund shares and/or total assets in the Fund. The amount of support may be affected by total sales; net sales; levels of redemptions; the dealers’ support of, and participation in, the Distributors’ marketing programs and the extent of a dealer’s marketing programs relating to the Fund. Financial support to dealers may be made from payments from the Distributors’ resources and from its retention of underwriting concessions.

CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS

The Statement of Additional Information (SAI) contains additional information about investment strategies and their related risks.

Credit and Counterparty Risk

The Fund is subject to the risk that the issuer or guarantor of a fixed-income security or other obligation, the counterparty to a derivatives contract or repurchase agreement, or the borrower of a portfolio’s securities will be unable or unwilling to make timely principal, interest, or settlement payments, or otherwise to honor its obligations.

Liquidity Risk

A fund is exposed to liquidity risk when trading volume, lack of a market maker, or legal restrictions impair the fund’s ability to sell particular securities or close derivative positions at an advantageous price. Funds with principal investment strategies that involve securities of companies with smaller market capitalizations, foreign securities, derivatives, or securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk.

Management Risk

The Fund is actively managed by its investment advisor or sub-advisor(s). The performance of a fund that is actively managed will reflect in part the ability of the advisor or sub-advisor(s) to make investment decisions that are suited to achieving the Fund’s investment objective. If the advisor’s or sub-advisor(s)’ strategies do not perform as expected, the Fund could underperform other mutual funds with similar investment objectives or lose money.

Securities and Investment Practices

Market Volatility. Equity securities include common stocks, preferred stocks, convertible securities, depositary receipts, rights and warrants. Common stocks, the most familiar type, represent an equity (ownership) interest in a corporation. The value of a company’s stock may fall as a result of factors directly relating to that company, such as

8 THE COSTS OF INVESTING  Principal Funds, Inc. 
  1-800-222-5852 


decisions made by its management or lower demand for the company’s products or services. A stock’s value may also fall because of factors affecting not just the company, but also companies in the same industry or in a number of different industries, such as increases in production costs. The value of a company’s stock may also be affected by changes in financial markets that are relatively unrelated to the company or its industry, such as changes in interest rates or currency exchange rates. In addition, a company’s stock generally pays dividends only after the company invests in its own business and makes required payments to holders of its bonds and other debt. For this reason, the value of a company’s stock will usually react more strongly than its bonds and other debt to actual or perceived changes in the company’s financial condition or prospects. Stocks of smaller companies may be more vulnerable to adverse developments than those of larger companies.

Fixed-income securities include bonds and other debt instruments that are used by issuers to borrow money from investors. The issuer generally pays the investor a fixed, variable, or floating rate of interest. The amount borrowed must be repaid at maturity. Some debt securities, such as zero coupon bonds, do not pay current interest, but are sold at a discount from their face values.

Interest Rate Changes. Fixed-income securities are sensitive to changes in interest rates. In general, fixed-income security prices rise when interest rates fall and fall when interest rates rise. Longer term bonds and zero coupon bonds are generally more sensitive to interest rate changes.

Credit Risk. Fixed-income security prices are also affected by the credit quality of the issuer. Investment grade debt securities are medium and high quality securities. Some bonds, such as lower grade or “junk” bonds, may have speculative characteristics and may be particularly sensitive to economic conditions and the financial condition of the issuers.

Repurchase Agreements and Loaned Securities

Although not a principal investment strategy, the Fund may invest a portion of its assets in repurchase agreements. Repurchase agreements typically involve the purchase of debt securities from a financial institution such as a bank, savings and loan association, or broker-dealer. A repurchase agreement provides that the Fund sells back to the seller and that the seller repurchases the underlying securities at a specified price on a specific date. Repurchase agreements may be viewed as loans by a Fund collateralized by the underlying securities. This arrangement results in a fixed rate of return that is not subject to market fluctuation while the Fund holds the security. In the event of a default or bankruptcy by a selling financial institution, the affected Fund bears a risk of loss. To minimize such risks, the Fund enters into repurchase agreements only with parties a Sub-Advisor deems creditworthy (those that are large, well-capitalized and well-established financial institutions). In addition, the value of the securities collateralizing the repurchase agreement is, and during the entire term of the repurchase agreement remains, at least equal to the repurchase price, including accrued interest.

The Fund may lend its portfolio securities to unaffiliated broker-dealers and other unaffiliated qualified financial institutions. These transactions involve a risk of loss to the Fund if the counterparty should fail to return such securities to the Fund upon demand or if the counterparty’s collateral invested by the Fund declines in value as a result of investment losses.

Bank Loans (also known as Senior Floating Rate Interests)

The Fund invests in bank loans. Bank loans hold the most senior position in the capital structure of a business entity (the “Borrower”), are typically secured by specific collateral, and have a claim on the assets and/or stock of the Borrower that is senior to that held by subordinated debtholders and stockholders of the Borrower. Bank loans are typically structured and administered by a financial institution that acts as the agent of the lenders participating in the bank loan. Bank loans are rated below-investment-grade, which means they are more likely to default than investment-grade loans. A default could lead to non-payment of income which would result in a reduction of income to the fund and there can be no assurance that the liquidation of any collateral would satisfy the Borrower’s obligation in the event of non-payment of scheduled interest or principal payments, or that such collateral could be readily liquidated.

Principal Funds, Inc.  CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS  9 
www.principal.com     


Bank loans pay interest at rates which are periodically reset by reference to a base lending rate plus a spread. These base lending rates are generally the prime rate offered by a designated U.S. bank or the London InterBank Offered Rate (LIBOR) or the prime rate offered by one or more major United States banks.

Bank loans generally are subject to mandatory and/or optional prepayment. Because of these mandatory prepayment conditions and because there may be significant economic incentives for the borrower to repay, prepayments of senior floating rate interests may occur.

Currency Contracts

The Fund may enter into forward currency contracts, currency futures contracts and options, and options on currencies for hedging and other purposes. A forward currency contract involves a privately negotiated obligation to purchase or sell a specific currency at a future date at a price set in the contract. The Fund will not hedge currency exposure to an extent greater than the aggregate market value of the securities held or to be purchased by the Fund (denominated or generally quoted or currently convertible into the currency).

Hedging is a technique used in an attempt to reduce risk. If the Fund’s Sub-Advisor hedges market conditions incorrectly or employs a strategy that does not correlate well with the Fund’s investment, these techniques could result in a loss. These techniques may increase the volatility of the Fund and may involve a small investment of cash relative to the magnitude of the risk assumed. In addition, these techniques could result in a loss if the other party to the transaction does not perform as promised. There is also a risk of government action through exchange controls that would restrict the ability of the Fund to deliver or receive currency.

Forward Commitments

Although not a principal investment strategy, the Fund may enter into forward commitment agreements. These agreements call for the Fund to purchase or sell a security on a future date at a fixed price. The Fund may also enter into contracts to sell its investments either on demand or at a specific interval.

Warrants

The Fund may invest in warrants though it will not use such investments as a principal investment strategy. A warrant is a certificate granting its owner the right to purchase securities from the issuer at a specified price, normally higher than the current market price.

Real Estate Investment Trusts

The Fund typically invests a significant portion of its net assets in REITs. REITs involve certain unique risks in addition to those risks associated with investing in the real estate industry in general (such as possible declines in the value of real estate, lack of availability of mortgage funds, or extended vacancies of property). Equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of any credit extended. REITs are dependent upon management skills, are not diversified, and are subject to heavy cash flow dependency, risks of default by borrowers, and self-liquidation. As an investor in a REIT, the Fund will be subject to the REIT’s expenses, including management fees, and will remain subject to the Fund’s advisory fees with respect to the assets so invested. REIT’s are also subject to the possibilities of failing to qualify for the special tax treatment accorded REITs under the Code, and failing to maintain their exemptions from registration under the 1940 Act.

High Yield Securities

The Fund may invest in debt securities rated BB or lower by S&P or Ba or lower by Moody’s or, if not rated, determined to be of equivalent quality by the Manager or the Sub-Advisor. Such securities are sometimes referred to as high yield or “junk bonds” and are considered speculative.

Investment in high yield bonds involves special risks in addition to the risks associated with investment in highly rated debt securities. High yield bonds may be regarded as predominantly speculative with respect to the issuer’s continuing ability to meet principal and interest payments. Moreover, such securities may, under certain circumstances, be less liquid than higher rated debt securities.

10  CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS  Principal Funds, Inc. 
    1-800-222-5852 


Analysis of the creditworthiness of issuers of high yield securities may be more complex than for issuers of higher quality debt securities. The ability of a Fund to achieve its investment objective may, to the extent of its investment in high yield bonds, be more dependent on such credit analysis than would be the case if the Fund were investing in higher quality bonds.

High yield bonds may be more susceptible to real or perceived adverse economic and competitive industry conditions than higher-grade bonds. The prices of high yield bonds have been found to be less sensitive to interest rate changes than more highly rated investments, but more sensitive to adverse economic downturns or individual corporate developments. If the issuer of high yield bonds defaults, the Fund may incur additional expenses to seek recovery.

The secondary market on which high yield bonds are traded may be less liquid than the market for higher-grade bonds. Less liquidity in the secondary trading market could adversely affect the price at which the Fund could sell a high yield bond and could adversely affect and cause large fluctuations in the daily price of the Fund’s shares. Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the value and liquidity of high yield bonds, especially in a thinly traded market.

The use of credit ratings for evaluating high yield bonds also involves certain risks. For example, credit ratings evaluate the safety of principal and interest payments, not the market value risk of high yield bonds. Also, credit rating agencies may fail to change credit ratings in a timely manner to reflect subsequent events. If a credit rating agency changes the rating of a portfolio security held by the Fund, the Fund may retain the security if the Manager or Sub-Advisor thinks it is in the best interest of shareholders.

Initial Public Offerings (“IPOs”)

The Fund may invest in IPOs. An IPO is a company’s first offering of stock to the public. IPO risk is that the market value of IPO shares will fluctuate considerably due to factors such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer. The purchase of IPO shares may involve high transaction costs. IPO shares are subject to market risk and liquidity risk. In addition, the market for IPO shares can be speculative and/or inactive for extended periods of time. The limited number of shares available for trading in some IPOs may make it more difficult for a Fund to buy or sell significant amounts of shares without an unfavorable impact on prevailing prices. Investors in IPO shares can be affected by substantial dilution in the value of their shares by sales of additional shares and by concentration of control in existing management and principal shareholders.

When the Fund’s asset base is small, a significant portion of the Fund’s performance could be attributable to investments in IPOs because such investments would have a magnified impact on the Fund. As the Fund’s assets grow, the effect of the Fund’s investments in IPOs on the Fund’s performance probably will decline, which could reduce the Fund’s performance. Because of the price volatility of IPO shares, a Fund may choose to hold IPO shares for a very short period of time. This may increase the turnover of the Fund’s portfolio and lead to increased expenses to the Fund, such as commissions and transaction costs. By selling IPO shares, the Fund may realize taxable gains it will subsequently distribute to shareholders.

Derivatives

To the extent permitted by its investment objectives and policies, the Fund may invest in securities that are commonly referred to as derivative securities. Generally, a derivative is a financial arrangement, the value of which is derived from, or based on, a traditional security, asset, or market index. Certain derivative securities are described more accurately as index/structured securities. Index/structured securities are derivative securities whose value or performance is linked to other equity securities (such as depositary receipts), currencies, interest rates, indices, or other financial indicators (reference indices).

Some derivatives, such as mortgage-related and other asset-backed securities, are in many respects like any other investment, although they may be more volatile or less liquid than more traditional debt securities.

There are many different types of derivatives and many different ways to use them. Futures and options are commonly used for traditional hedging purposes to attempt to protect a Fund from exposure to changing interest rates, securities prices, or currency exchange rates and for cash management purposes as a low-cost method of gaining exposure to a

Principal Funds, Inc.  CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS  11

particular securities market without investing directly in those securities. The Fund may enter into put or call options, futures contracts, options on futures contracts, over-the-counter swap contracts (e.g., interest rate swaps, total return swaps and credit default swaps), and forward currency contracts for both hedging and non-hedging purposes.

Generally, the Fund may not invest in a derivative security unless the reference index or the instrument to which it relates is an eligible investment for the Fund or the reference currency relates to an eligible investment for the Fund.

The return on a derivative security may increase or decrease, depending upon changes in the reference index or instrument to which it relates. The risks associated with derivative investments include:

·      the risk that the underlying security, interest rate, market index, or other financial asset will not move in the direction the Manager or Sub-Advisor anticipated;
 
·      the possibility that there may be no liquid secondary market which may make it difficult or impossible to close out a position when desired;
 
·      the risk that adverse price movements in an instrument can result in a loss substantially greater than a Fund’s initial investment; and
 
·      the possibility that the counterparty may fail to perform its obligations.
 

Exchange Traded Funds (ETFs)

These are a type of index or actively managed fund bought and sold on a securities exchange. An ETF trades like common stock. Shares in an index ETF represent an interest in a fixed portfolio of securities designed to track a particular market index. The Fund could purchase shares issued by an ETF to temporarily gain exposure to a portion of the U.S. or a foreign market while awaiting purchase of underlying securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities they are designed to track, although ETFs have management fees that increase their costs.

Convertible Securities

Convertible securities are fixed-income securities that a Fund has the right to exchange for equity securities at a specified conversion price. The option allows the Fund to realize additional returns if the market price of the equity securities exceeds the conversion price. For example, the Fund may hold fixed-income securities that are convertible into shares of common stock at a conversion price of $10 per share. If the market value of the shares of common stock reached $12, the Fund could realize an additional $2 per share by converting its fixed-income securities.

Convertible securities have lower yields than comparable fixed-income securities. In addition, at the time a convertible security is issued the conversion price exceeds the market value of the underlying equity securities. Thus, convertible securities may provide lower returns than non-convertible fixed-income securities or equity securities depending upon changes in the price of the underlying equity securities. However, convertible securities permit the Fund to realize some of the potential appreciation of the underlying equity securities with less risk of losing its initial investment.

The Fund treats convertible securities as both fixed-income and equity securities for purposes of investment policies and limitations because of their unique characteristics. The Fund may invest in convertible securities without regard to their ratings.

Foreign Investing

As a principal investment strategy, the Fund may invest Fund assets in securities of foreign companies. For the purpose of this restriction, foreign companies are:

·      companies with their principal place of business or principal office outside the U.S. or
 
·      companies for which the principal securities trading market is outside the U.S.
 

Foreign companies may not be subject to the same uniform accounting, auditing, and financial reporting practices as are required of U.S. companies. In addition, there may be less publicly available information about a foreign company than about a U.S. company. Securities of many foreign companies are less liquid and more volatile than securities of comparable U.S. companies. Commissions on foreign securities exchanges may be generally higher than those on U.S. exchanges.

12  CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS  Principal Funds, Inc. 
    1-800-222-5852 


Foreign markets also have different clearance and settlement procedures than those in U.S. markets. In certain markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct these transactions. Delays in settlement could result in temporary periods when a portion of Fund assets is not invested and earning no return. If the Fund is unable to make intended security purchases due to settlement problems, the Fund may miss attractive investment opportunities. In addition, the Fund may incur a loss as a result of a decline in the value of its portfolio if it is unable to sell a security.

With respect to certain foreign countries, there is the possibility of expropriation or confiscatory taxation, political or social instability, or diplomatic developments that could affect the Fund’s investments in those countries. In addition, the Fund may also suffer losses due to nationalization, expropriation, or differing accounting practices and treatments. Investments in foreign securities are subject to laws of the foreign country that may limit the amount and types of foreign investments. Changes of governments or of economic or monetary policies, in the U.S. or abroad, changes in dealings between nations, currency convertibility or exchange rates could result in investment losses for the Fund. Finally, even though certain currencies may be convertible into U.S. dollars, the conversion rates may be artificial relative to the actual market values and may be unfavorable to Fund investors.

Foreign securities are often traded with less frequency and volume, and therefore may have greater price volatility, than is the case with many U.S. securities. Brokerage commissions, custodial services, and other costs relating to investment in foreign countries are generally more expensive than in the U.S. Though the Fund intends to acquire the securities of foreign issuers where there are public trading markets, economic or political turmoil in a country in which the Fund has a significant portion of its assets or deterioration of the relationship between the U.S. and a foreign country may negatively impact the liquidity of the Fund’s portfolio. The Fund may have difficulty meeting a large number of redemption requests. Furthermore, there may be difficulties in obtaining or enforcing judgments against foreign issuers.

The Fund may choose to invest in a foreign company by purchasing depositary receipts. Depositary receipts are certificates of ownership of shares in a foreign-based issuer held by a bank or other financial institution. They are alternatives to purchasing the underlying security but are subject to the foreign securities to which they relate.

Investments in companies of developing (also called “emerging”) countries are subject to higher risks than investments in companies in more developed countries. These risks include:

·      increased social, political, and economic instability;
 
·      a smaller market for these securities and low or nonexistent volume of trading that results in a lack of liquidity and in greater price volatility;
 
·      lack of publicly available information, including reports of payments of dividends or interest on outstanding securities;
 
·      foreign government policies that may restrict opportunities, including restrictions on investment in issuers or industries deemed sensitive to national interests;
 
·      relatively new capital market structure or market-oriented economy;
 
·      the possibility that recent favorable economic developments may be slowed or reversed by unanticipated political or social events in these countries;
 
·      restrictions that may make it difficult or impossible for the Fund to vote proxies, exercise shareholder rights, pursue legal remedies, and obtain judgments in foreign courts; and
 
·      possible losses through the holding of securities in domestic and foreign custodial banks and depositories.
 

In addition, many developing countries have experienced substantial and, in some periods, extremely high rates of inflation for many years. Inflation and rapid fluctuations in inflation rates have had and may continue to have negative effects on the economies and securities markets of those countries.

Repatriation of investment income, capital, and proceeds of sales by foreign investors may require governmental registration and/or approval in some developing countries. The Fund could be adversely affected by delays in or a refusal to grant any required governmental registration or approval for repatriation.

Further, the economies of developing countries generally are heavily dependent upon international trade and, accordingly, have been and may continue to be adversely affected by trade barriers, exchange controls, managed

Principal Funds, Inc.  CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS  13

adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which they trade.

Small and Medium Capitalization Companies

The Fund may hold securities of small and medium capitalization companies but not as a principal investment strategy. The international funds invest in the securities of foreign companies without regard to the market capitalizations of those companies. Market capitalization is defined as total current market value of a company’s outstanding common stock. Investments in companies with smaller market capitalizations may involve greater risks and price volatility (wide, rapid fluctuations) than investments in larger, more mature companies. Small companies may be less significant within their industries and may be at a competitive disadvantage relative to their larger competitors. While smaller companies may be subject to these additional risks, they may also realize more substantial growth than larger or more established companies.

Smaller companies may be less mature than larger companies. At this earlier stage of development, the companies may have limited product lines, reduced market liquidity for their shares, limited financial resources, or less depth in management than larger or more established companies. Unseasoned issuers are companies with a record of less than three years continuous operation, including the operation of predecessors and parents. Unseasoned issuers by their nature have only a limited operating history that can be used for evaluating the company’s growth prospects. As a result, investment decisions for these securities may place a greater emphasis on current or planned product lines and the reputation and experience of the company’s management and less emphasis on fundamental valuation factors than would be the case for more mature growth companies.

Temporary Defensive Measures

From time to time, as part of its investment strategy, the Fund may invest without limit in cash and cash equivalents for temporary defensive purposes in response to adverse market, economic, or political conditions. To the extent that the Fund is in a defensive position, it may lose the benefit of upswings and limit its ability to meet its investment objective. For this purpose, cash equivalents include: bank notes, bank certificates of deposit, bankers’ acceptances, repurchase agreements, commercial paper, and commercial paper master notes which are floating rate debt instruments without a fixed maturity. In addition, the Fund may purchase U.S. government securities, preferred stocks, and debt securities, whether or not convertible into or carrying rights for common stock.

There is no limit on the extent to which the Fund may take temporary defensive measures. In taking such measures, the Fund may fail to achieve its investment objective.

Portfolio Turnover

“Portfolio Turnover” is the term used in the industry for measuring the amount of trading that occurs in a Fund’s portfolio during the year. For example, a 100% turnover rate means that on average every security in the portfolio has been replaced once during the year.

Funds with high turnover rates (more than 100%) often have higher transaction costs (which are paid by the Fund) which may have an adverse impact on the Fund’s performance.

Please consider all the factors when you compare the turnover rates of different funds. A fund with consistently higher total returns and higher turnover rates than another fund may actually be achieving better performance precisely because the managers are active traders.

Duties of Principal and Sub-Advisors

Principal or the Sub-Advisor provides the Directors of the Fund with a recommended investment program. The program must be consistent with the Fund’s investment objective and policies. Within the scope of the approved investment program, the Sub-Advisor advises the Fund on its investment policy and determines which securities are bought or sold, and in what amounts.

This Fund has multiple Sub-Advisors. Principal determines the portion of the Fund’s assets each Sub-Advisor will manage and may, from time-to-time, reallocate Fund assets between the Sub-Advisors. The decision to do so may be based on a variety of factors, including but not limited to: the investment capacity of each Sub-Advisor, portfolio diversification, volume of net cash flows, fund liquidity, investment performance, investment strategies, changes in each Sub-Advisor’s firm or investment professionals or changes in the number of Sub-Advisors. Ordinarily, reallocations of Fund assets among Sub-Advisors will generally occur as a Sub-Advisor liquidates assets in the normal course of portfolio management and with net new cash flows; however, at times, existing Fund assets may be reallocated among Sub-Advisors.

Fees Paid to Principal

The Fund pays Principal a fee for its services, which includes any fee Principal pays to the Sub-Advisor. The fee the Fund will pay (as a percentage of the average daily net assets) is:

0.80% on the first $500 million 
0.78% on the next $500 million 
0.76% on the next $500 million 
0.75% on the next $500 million 
0.73% on the next $1.0 billion 
0.70% on assets over $3.0 billion 

A discussion regarding the basis for the Board of Directors approving the management agreement with Principal and the sub-advisory agreements with these Sub-Advisors will be included in the annual report to shareholders for the fiscal year ended October 31, 2008, which will be available 60 days after that date.

Under an order received from the SEC, the Fund and Principal, may enter into and materially amend agreements with Sub-Advisors, other than those affiliated with Principal, without obtaining shareholder approval. For any Fund that is relying on that order, Principal may, without obtaining shareholder approval:

  hire one or more Sub-Advisors; 
  change Sub-Advisors; and 
  reallocate management fees between itself and Sub-Advisors. 

Principal has ultimate responsibility for the investment performance of each Fund that utilizes a Sub-Advisor due to its responsibility to oversee Sub-Advisors and recommend their hiring, termination, and replacement. No Fund will rely on the order until it receives approval from its shareholders or, in the case of a new Fund, the Fund’s sole initial shareholder before the Fund is available to the other purchasers, and the Fund states in its prospectus that it intends to rely on the order.

The shareholders of the Fund have approved the Fund’s reliance on the order; however, the Fund does not intend to rely on the order.

Distribution Agreements

Principal may pay compensation, from its own resources, to certain financial intermediaries for the distribution, promotion, sale of Fund shares, and for providing services to shareholders. If one mutual fund sponsor makes greater distribution assistance payments than another, your investment representative or his or her financial intermediary may have an incentive to recommend one fund complex over another.

PRICING OF FUND SHARES

The Fund’s shares are bought and sold at the current share price. The share price of each class of the Fund is calculated each day the New York Stock Exchange (“NYSE”) is open (shares are not priced on the days on which the NYSE is closed for trading, generally New Year’s Day, Martin Luther King, Jr. Day, Washington’s Birthday/Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas). The share price is determined as of the close of business of the NYSE (normally 3:00 p.m. Central Time). When an order to buy or sell shares is received, the share price used to fill the order is the next price calculated after the order is received in good order by us at our transaction processing center in Canton, Massachusetts. In order for us to process your purchase order on the day it is received, we must receive the order (with complete information):

  on a day that the NYSE is open and 
  prior to the close of trading on the NYSE (normally 3 p.m. Central Time). 

18  PRICING OF FUND SHARES  Principal Funds, Inc. 
    1-800-222-5852 


Orders received after the close of the NYSE or on days that the NYSE is not open will be processed on the next day that the NYSE is open for normal trading.

If we receive an application or purchase request for a new mutual fund account or subsequent purchase into an existing account that is accompanied by a check and the application or purchase request does not contain complete information, we may hold the application (and check) for up to two business days while we attempt to obtain the necessary information. If we receive the necessary information within two business days, we will process the order using the next share price calculated. If we do not receive the information within two business days, the application and check will be returned to you.

For this Fund, the share price is calculated by:

·      taking the current market value of the total assets of the Fund
 
·      subtracting liabilities of the Fund
 
·      dividing the remainder proportionately into the classes of the Fund
 
·      subtracting the liability of each class
 
·      dividing the remainder by the total number of shares owned in that class.
 

NOTES:

·      If market quotations are not readily available for a security owned by the Fund, its fair value is determined using a policy adopted by the Directors. Fair valuation pricing is subjective and creates the possibility that the fair value determined for a security may differ materially from the value that could be realized upon the sale of the security.
 
·      The Fund’s securities may be traded on foreign securities markets that generally complete trading at various times during the day prior to the close of the NYSE. Generally, the values of foreign securities used in computing a Fund’s NAV are the market quotations as of the close of the foreign market. Foreign securities and currencies are also converted to U.S. dollars using the exchange rate in effect at the close of the NYSE. Occasionally, events affecting the value of foreign securities occur when the foreign market is closed and the NYSE is open. The Fund has adopted policies and procedures to “fair value” some or all securities held by the Fund if significant events occur after the close of the market on which the foreign securities are traded but before the Fund’s NAV is calculated.
 
  Significant events can be specific to a single security or can include events that affect a particular foreign market or markets. A significant event can also include a general market movement in the U.S. securities markets. If Principal believes that the market value of any or all of the foreign securities is materially affected by such an event, the securities will be valued, and the Fund’s NAV will be calculated, using the policy adopted by the Fund. These fair valuation procedures are intended to discourage shareholders from investing in the Fund for the purpose of engaging in market timing or arbitrage transactions.
 
  The trading of foreign securities generally or in a particular country or countries may not take place on all days the NYSE is open, or may trade on days the NYSE is closed. Thus, the value of the foreign securities held by the Fund may change on days when shareholders are unable to purchase or redeem shares.
 
·      Certain securities issued by companies in emerging market countries may have more than one quoted valuation at any point in time. These may be referred to as local price and premium price. The premium price is often a negotiated price that may not consistently represent a price at which a specific transaction can be effected. The Fund has a policy to value such securities at a price at which the Sub-Advisor expects the securities may be sold.
 

PURCHASE OF FUND SHARES

Shares may be purchased from Princor or PFD, the Principal Funds’ principal underwriters for Institutional Class shares. There are no sales charges on Institutional Class shares of the Fund. There are no restrictions on amounts to be invested in Institutional Class shares of the Fund.

Shareholder accounts for the Fund are maintained under an open account system. Under this system, an account is opened and maintained for each investor. Each investment is confirmed by sending the investor a statement of

Principal Funds, Inc.  PURCHASE OF FUND SHARES  19 
www.principal.com     


account showing the current purchase or sale and the total number of shares owned. The statement of account is treated by the Fund as evidence of ownership of Fund shares. Share certificates are not issued.

The Fund may reject or cancel any purchase orders for any reason. For example, the Fund does not intend to permit market timing because short-term or other excessive trading into and out of the Funds may harm performance by disrupting portfolio management strategies and by increasing expenses. Accordingly, the Fund may reject any purchase orders from market timers or investors that, in Principal’s opinion, may be disruptive to the Fund. For these purposes, Principal may consider an investor’s trading history in the Fund or other Funds sponsored by Principal Life and accounts under common ownership or control.

Payments are to be made via personal or financial institution check (for example, a bank or cashier’s check). We reserve the right to refuse any payment that we feel presents a fraud or money laundering risk. Examples of the types of payments we will not accept are cash, money orders, travelers’ checks, credit card checks, and foreign checks.

Principal may recommend to the Board, and the Board may elect, to close certain funds to new and existing investors.

REDEMPTION OF FUND SHARES

You may redeem shares of the Fund upon request. There is no charge for the redemption. Shares are redeemed at the NAV per share next computed after the request is received by the Fund in proper and complete form.

The Fund generally sends payment for shares sold the business day after the sell order is received. Under unusual circumstances, the Fund may suspend redemptions, or postpone payment for more than seven days, as permitted by federal securities law.

Distributions in Kind. Payment for shares of the Fund tendered for redemption is ordinarily made by check. However, the Fund may determine that it would be detrimental to the remaining shareholders of a Fund to make payment of a redemption order wholly or partly in cash. Under certain circumstances, therefore, the Fund may pay the redemption proceeds in whole or in part by a distribution “in kind” of securities from the Fund’s portfolio in lieu of cash. If the Fund pays the redemption proceeds in kind, the redeeming shareholder might incur brokerage or other costs in selling the securities for cash. The Fund will value securities used to pay redemptions in kind using the same method the Fund uses to value its portfolio securities as described in this prospectus.

Redemption fees. The Fund board of directors has determined that it is not necessary to impose a fee upon the redemption of fund shares, because the Fund has adopted transfer restrictions as described in “Exchange of Fund Shares.”

EXCHANGE OF FUND SHARES

An exchange between Funds is a redemption of shares of one Fund and a concurrent purchase of shares in another Fund with the redemption proceeds. A shareholder, including a beneficial owner of shares held in nominee name or a participant in a participant-directed employee benefit plan, may exchange Fund shares under certain circumstances. In addition to any restrictions an intermediary or an employee benefit plan imposes, Fund shares may be exchanged, without charge, for shares of any other Fund of Principal Funds, provided that:

·      the shareholder has not exchanged shares of the Fund within 30 days preceding the exchange, unless the shareholder is exchanging into the Money Market Fund,
·      the share class of such other Fund is available through the plan, and
·      the share class of such other Fund is available in the shareholder’s state of residence.

All exchanges completed on the same day are considered a single exchange for purposes of this exchange limitation. In addition, the Fund will reject an order to purchase shares of any Fund, except shares of the Money Market Fund, if the shareholder redeemed shares from that Fund within the preceding 30-day period. The 30-day exchange or purchase restriction does not apply to exchanges or purchases made on a scheduled basis such as scheduled periodic portfolio rebalancing transactions.

20  REDEMPTION OF FUND SHARES  Principal Funds, Inc. 
    1-800-222-5852 


If Fund shares are purchased through an intermediary that is unable or unwilling to impose the 30-day exchange restriction described above, Fund management may waive this restriction in lieu of the exchange limitation that the intermediary is able to impose if, in management’s judgment, such limitation is reasonably likely to prevent excessive trading in Fund shares. In order to prevent excessive exchanges, and under other circumstances where the Fund Board of Directors or the Manager believes it is in the best interests of the Fund, the Fund reserves the right to revise or terminate this exchange privilege, limit the amount or further limit the number of exchanges, reject any exchange or close an account.

DIVIDENDS AND DISTRIBUTIONS

Dividends are based on estimates of income, expenses, and shareholder activity for the Fund. Actual income, expenses, and shareholder activity may differ from estimates; consequently, differences, if any, will be included in the calculation of subsequent dividends. The Fund pays its net investment income to shareholders of record on the business day prior to the payment date. The Fund declares dividends of its daily net investment income each day its shares are priced. On the last business day of each month the Fund will pay out its accumulated declared dividends.

Net realized capital gains, if any, are distributed annually. Generally the distribution is made on the fourth business day of December. Payments are made to shareholders of record on the business day prior to the payable date. Capital gains may be taxable at different rates, depending on the length of time that the Fund holds its assets.

Dividend and capital gains distributions will be reinvested, without a sales charge, in shares of the Fund from which the distribution is paid.

Generally, for federal income tax purposes, Fund distributions are taxable as ordinary income, except that any distributions of long-term capital gains will be taxed as such regardless of how long Fund shares have been held. Special tax rules apply to Fund distributions to retirement plans. A tax advisor should be consulted to determine the suitability of the Fund as an investment by such a plan and the tax treatment of distributions by the Fund. A tax advisor can also provide information on the potential impact of possible foreign, state, and local taxes. A Fund’s investments in foreign securities may be subject to foreign withholding taxes. In that case, the Fund’s yield on those securities would be decreased.

To the extent that distributions the Fund pays are derived from a source other than net income (such as a return of capital), a notice will be included in your quarterly statement pursuant to Section 19(a) of the Investment Company Act of 1940, as amended, and Rule 19a-1 disclosing the source of such distributions. Furthermore, such notices shall be posted monthly on our web site at www.principalfunds.com. You may request a copy of all such notices, free of charge, by telephoning 1-800-222-5852. The amounts and sources of distributions included in such notices are estimates only and you should not rely upon them for purposes of reporting income taxes. The Fund will send shareholders a Form 1099-DIV for the calendar year that will tell shareholders how to report these distributions for federal income tax purposes.

FREQUENT PURCHASES AND REDEMPTIONS

The Fund is not designed for frequent trading or market timing activity. The fund does not knowingly accommodate frequent purchases and redemptions of fund shares by investors. If you intend to trade frequently and/or use market timing investment strategies, you should not purchase this Fund.

We consider frequent trading and market timing activities to be abusive trading practices because they:

·      Disrupt the management of the Fund by
  ·      forcing the Fund to hold short-term (liquid) assets rather than investing for long term growth, which results in lost investment opportunities for the Fund and
  ·      causing unplanned portfolio turnover;
·      Hurt the portfolio performance of the Fund; and
·      Increase expenses of the Fund due to
  ·      increased broker-dealer commissions and
 
Principal Funds, Inc.  DIVIDENDS AND DISTRIBUTIONS  21 
www.principal.com     


• increased recordkeeping and related costs.

Certain Funds may be at greater risk for abusive trading practices. For example, those Funds that invest in foreign securities may appeal to investors attempting to take advantage of time-zone arbitrage. If we are not able to identify such abusive trading practices, the abuses described above will negatively impact the Fund.

We have adopted policies and procedures to help us identify and prevent abusive trading practices. In addition, the Fund monitors trading activity to identify and take action against abuses. While our policies and procedures are designed to identify and protect against abusive trading practices, there can be no certainty that we will identify and prevent abusive trading in all instances. When we do identify abusive trading, we will apply our policies and procedures in a fair and uniform manner.

If we, or the Fund, deem abusive trading practices to be occurring, we will take action that may include, but is not limited to:

•      Rejecting exchange instructions from the shareholder or other person authorized by the shareholder to direct 
       exchanges; 
•      Restricting submission of exchange requests by, for example, allowing exchange requests to be submitted by 
       1st class U.S. mail only and disallowing requests made by facsimile, overnight courier, telephone or via the 
       internet; 
•      Limiting the number of exchanges during a year; 
•      Requiring a holding period of a minimum of 30 days before permitting exchanges among the Funds where there is 
       evidence of at least one round-trip exchange (exchange or redemption of shares that were purchased within 
       30 days of the exchange/redemption); and 
•      Taking such other action as directed by the Fund. 

The Fund has reserved the right to accept or reject, without prior written notice, any exchange requests. In some instances, an exchange may be completed prior to a determination of abusive trading. In those instances, we will reverse the exchange. We will give you notice in writing in this instance.

FUND ACCOUNT INFORMATION

Orders Placed by Intermediaries

Principal Funds may have an agreement with your intermediary, such as a broker-dealer, third party administrator, or trust company, that permits the intermediary to accept orders on behalf of the Fund until 3 p.m. Central Time. The agreement may include authorization for your intermediary to designate other intermediaries (“sub-designees”) to accept orders on behalf of the Fund on the same terms that apply to the intermediary. In such cases, if your intermediary or a sub-designee receives your order in correct form by 3 p.m. Central Time, transmits it to the Fund, and pays for it in accordance with the agreement, the Fund will price the order at the next net asset value per share it computes after your intermediary or sub-designee received your order. Note: The time at which the Fund prices orders and the time until which the Fund or your intermediary or sub-designee will accept orders may change in the case of an emergency or if the NYSE closes at a time other than 3 p.m. Central Time.

Signature Guarantees

Certain transactions require that your signature be guaranteed. If required, the signature(s) must be guaranteed by a commercial bank, trust company, credit union, savings and loan, national securities exchange member, or brokerage firm. A signature guaranteed by a notary public or savings bank is not acceptable. Signature guarantees are required:

•      if you sell more than $100,000 from the Fund; 
•      if a sales proceeds check is payable to other than the account shareholder(s); 
•      to change ownership of an account; 
•      to add telephone transaction services and/or wire privileges to an existing account; 
•      to change bank account information designated under an existing telephone withdrawal plan; 
•      to exchange or transfer among accounts with different ownership; and 
•      to have a sales proceeds check mailed to an address other than the address on the account or to the address on 
       the account if it has been changed within the preceding 30 days.

APPENDIX A

SUMMARY OF PRINCIPAL RISKS

The value of your investment in a Fund changes with the value of the investments held by that Fund. Many factors affect that value, and it is possible that you may lose money by investing in the Fund. Factors that may adversely affect a particular Fund as a whole are called “principal risks.” The principal risks of investing in the Funds are stated above as to the Fund in its description. Each of these risks is summarized below. Additional information about the Fund, its investments, and the related risks is located under “Certain Investment Strategies and Related Risks” and in the Statement of Additional Information.

Active Trading Risk

A fund that actively trades portfolio securities in an attempt to achieve its investment objective may have high portfolio turnover rates that may increase the fund’s brokerage costs, accelerate the realization of taxable gains, and adversely impact fund performance.

Derivatives Risk

Derivatives are investments whose values depend on or are derived from other securities or indexes. A fund’s use of certain derivative instruments (such as options, futures, and swaps) could produce disproportionate gains or losses. Derivatives are generally considered riskier than direct investments and, in a down market, could become harder to value or sell at a fair price.

Emerging Market Risk

Investments in emerging market countries involve special risks. Certain emerging market countries have historically experienced, and may continue to experience, certain economic problems. These may include: high rates of inflation, high interest rates, exchange rate fluctuations, large amounts of debt, balance of payments and trade difficulties, and extreme poverty and unemployment.

Equity Securities Risk

Equity securities include common, preferred, and convertible preferred stocks and securities the values of which are tied to the price of stocks, such as rights, warrants, and convertible debt securities. Common and preferred stocks represent equity ownership in a company. Stock markets are volatile, and the price of equity securities (and their equivalents) will fluctuate. The value of equity securities purchased by a fund could decline if the financial condition of the companies in which the fund invests decline or if overall market and economic conditions deteriorate.

Exchange Rate Risk

Because foreign securities are generally denominated in foreign currencies, the value of the net assets of a fund as measured in U.S. dollars will be affected by changes in exchange rates. To protect against future uncertainties in foreign currency exchange rates, the funds are authorized to enter into certain foreign currency exchange transactions. In addition, the funds’ foreign investments may be less liquid and their price more volatile than comparable investments in U.S. securities. Settlement periods may be longer for foreign securities and portfolio liquidity may be affected.

Fixed-Income Securities Risk

Fixed-income securities are generally subject to two principal types of risks: interest rate risk and credit quality risk.

Interest Rate Risk. Fixed-income securities are affected by changes in interest rates. When interest rates decline, the market value of the fixed-income securities generally can be expected to rise. Conversely, when interest rates rise, the market value of fixed-income securities generally can be expected to decline.

Credit Quality Risk. Fixed-income securities are subject to the risk that the issuer of the security will not repay all or a portion of the principal borrowed and will not make all interest payments. If the credit quality of a fixed income security deteriorates after a fund has purchased the security, the market value of the security may decrease and lead to a decrease in the value of the fund’s investments. Lower quality and longer maturity bonds will be subject to greater

24  APPENDIX A  Principal Funds, Inc. 
    1-800-222-5852 


credit risk and price fluctuations than higher quality and shorter maturity bonds. Bonds held by a fund may be affected by unfavorable political, economic, or government developments that could affect the repayment of principal or the payment of interest.

Foreign Securities Risk

Foreign securities carry risks that are not generally found in securities of U.S. companies. These risks include the loss of value as a result of political instability and financial and economic events in foreign countries. In addition, nationalization, expropriation or confiscatory taxation, and foreign exchange restrictions could adversely affect a fund’s investments in a foreign country. Foreign securities may be subject to less stringent reporting, accounting, and disclosure standards than are required of U.S. companies, and foreign countries may also have problems associated with and causing delays in the settlement of sales.

High Yield Securities Risk

Fixed-income securities that are not investment grade are commonly referred to as high yield securities or “junk bonds.” While these securities generally provide greater income potential than investments in higher rated fixed-income securities, there is a greater risk that principal and interest payments will not be made. Issuers of these securities may even go into default or become bankrupt. High yield securities generally involve greater price volatility and may be less liquid than higher rated fixed-income securities. High yield securities are considered speculative by the major credit rating agencies.

Portfolio Duration Risk

Portfolio duration is a measure of the expected life of a fixed-income security that is used to determine the sensitivity of a security’s price to changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Real Estate Securities Risk

Real estate investment trusts (“REITs”) or other real estate-related securities are subject to the risks associated with direct ownership of real estate, including declines in the value of real estate, risks related to general and local economic conditions, increases in property taxes and operating expenses, changes in zoning laws, changes in interest rates, and liabilities resulting from environmental problems. Equity and mortgage REITs are dependent on management skills and generally are not diversified. Equity REITs are affected by the changes in the value of the properties owned by the trust. Mortgage REITs are affected by the quality of the credit extended. Both equity and mortgage REITs:

·      may not be diversified with regard to the types of tenants (thus subject to business developments of the tenant(s));
·      may not be diversified with regard to the geographic locations of the properties (thus subject to regional economic developments);
·      are subject to cash flow dependency and defaults by borrowers; and
·      could fail to qualify for tax-free pass-through of income under the Internal Revenue Code.

Securities Lending Risk

The principal risk of securities lending is that the financial institution that borrows securities from the Fund could go bankrupt or otherwise default on its commitment under the securities lending agreement and the Fund might not be able to recover the loaned securities or their value.

Value Stock Risk

A fund’s investments in value stocks carry the risk that the market will not recognize a security’s intrinsic value for a long time or that a stock judged to be undervalued may actually be appropriately priced. A value stock may not increase in price if other investors fail to recognize the company’s value and bid up the price or invest in markets favoring faster growing companies. A fund’s strategy of investing in value stocks also carries the risk that in certain markets value stocks will underperform growth stocks.

APPENDIX B

Description of Bond Ratings:

Moody’s Investors Service, Inc. Rating Definitions:

Long-Term Obligation Ratings

Moody’s long-term obligation ratings are opinions of the relative credit risk of fixed-income obligations with an original maturity of one year or more. They address the possibility that a financial obligation will not be honored as promised. Such ratings reflect both the likelihood of default and any financial loss suffered in the event of default.

Aaa:  Obligations rated Aaa are judged to be of the highest quality, with minimal credit risk. 
Aa:  Obligations rated Aa are judged to be of high quality and are subject to very low credit risk. 
A:  Obligations rated A are considered upper-medium grade and are subject to low credit risk. 
Baa:  Obligations rated Baa are subject to moderate credit risk. They are considered medium-grade and as such 
  may possess certain speculative characteristics. 
Ba:  Obligations rated Ba are judged to have speculative elements and are subject to substantial credit risk. 
B:  Obligations rated B are considered speculative and are subject to high credit risk. 
Caa:  Obligations rated Caa are judged to be of poor standing and are subject to very high credit risk. 
Ca:  Obligations rated Ca are highly speculative and are likely in, or very near, default, with some prospect of 
  recovery of principal and interest. 
C:  Obligations rated C are the lowest rated class of bonds and are typically in default, with little prospect for 
  recovery of principal or interest. 

NOTE: Moody’s appends numerical modifiers, 1, 2, and 3 to each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category, the modifier 2 indicates a mid-range ranking, and the modifier 3 indicates a ranking in the lower end of that generate rating category.

SHORT-TERM NOTES: The four ratings of Moody’s for short-term notes are MIG 1, MIG 2, MIG 3, and MIG 4. MIG 1 denotes “best quality, enjoying strong protection from established cash flows.” MIG 2 denotes “high quality” with “ample margins of protection.” MIG 3 notes are of “favorable quality...but lacking the undeniable strength of the preceding grades.” MIG 4 notes are of “adequate quality, carrying specific risk for having protection...and not distinctly or predominantly speculative.”

Description of Moody’s Commercial Paper Ratings:

Moody’s Commercial Paper ratings are opinions of the ability to repay punctually promissory obligations not having an original maturity in excess of nine months. Moody’s employs the following three designations, all judged to be investment grade, to indicate the relative repayment capacity of rated issuers:

Issuers rated Prime-1 (or related supporting institutions) have a superior capacity for repayment of short-term promissory obligations.

Issuers rated Prime-2 (or related supporting institutions) have a strong capacity for repayment of short-term promissory obligations.

Issuers rated Prime-3 (or related supporting institutions) have an acceptable capacity for repayment of short-term promissory obligations.

Issuers rated Not Prime do not fall within any of the Prime rating categories.

Description of Standard & Poor’s Corporation’s Debt Ratings:

A Standard & Poor’s debt rating is a current assessment of the creditworthiness of an obligor with respect to a specific obligation. This assessment may take into consideration obligors such as guarantors, insurers, or lessees.

The debt rating is not a recommendation to purchase, sell or hold a security, inasmuch as it does not comment as to market price or suitability for a particular investor.

The ratings are based on current information furnished by the issuer or obtained by Standard & Poor’s from other sources Standard & Poor’s considers reliable. Standard & Poor’s does not perform an audit in connection with any rating and may, on occasion, rely on unaudited financial information. The ratings may be changed, suspended, or withdrawn as a result of changes in, or unavailability of, such information, or for other circumstances.

The ratings are based, in varying degrees, on the following considerations:

I.  Likelihood of default – capacity and willingness of the obligor as to the timely payment of interest and 
  repayment of principal in accordance with the terms of the obligation; 
 
 
II.  Nature of and provisions of the obligation; 
 
 
III.  Protection afforded by, and relative position of, the obligation in the event of bankruptcy, reorganization, or 
  other arrangement under the laws of bankruptcy and other laws affecting creditor’s rights. 
 
 
AAA:  Debt rated “AAA” has the highest rating assigned by Standard & Poor’s. Capacity to pay interest and repay 
  principal is extremely strong. 
 
 
AA:  Debt rated “AA” has a very strong capacity to pay interest and repay principal and differs from the highest- 
  rated issues only in small degree. 

Principal Funds, Inc.  APPENDIX B  27 
www.principal.com     


A:  Debt rated “A” has a strong capacity to pay interest and repay principal although they are somewhat more 
  susceptible to the adverse effects of changes in circumstances and economic conditions than debt in 
  higher-rated categories. 
 
 
BBB:  Debt rated “BBB” is regarded as having an adequate capacity to pay interest and repay principal. Whereas 
  it normally exhibits adequate protection parameters, adverse economic conditions or changing 
  circumstances are more likely to lead to a weakened capacity to pay interest and repay principal for debt in 
  this category than for debt in higher-rated categories. 

BB, B, CCC, CC:  Debt rated “BB,” “B,” “CCC,” and “CC” is regarded, on balance, as predominantly 
  speculative with respect to capacity to pay interest and repay principal in accordance with 
  the terms of the obligation. “BB” indicates the lowest degree of speculation and “CC” the 
  highest degree of speculation. While such debt will likely have some quality and 
  protective characteristics, these are outweighed by large uncertainties or major risk 
  exposures to adverse conditions. 

C: The rating “C” is reserved for income bonds on which no interest is being paid.
D:  Debt rated “D” is in default, and payment of interest and/or repayment of principal is in arrears. 

Plus (+) or Minus (-): The ratings from “AA” to “B” may be modified by the addition of a plus or minus sign to show 
relative standing within the major rating categories. 
 
Provisional Ratings: The letter “p” indicates that the rating is provisional. A provisional rating assumes the successful 
completion of the project being financed by the bonds being rated and indicates that payment of debt service 
requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, 
however, while addressing credit quality subsequent to completion of the project, makes no comment on the likelihood 
of, or the risk of default upon failure of, such completion. The investor should exercise his own judgment with respect 
to such likelihood and risk. 
 
 
NR:  Indicates that no rating has been requested, that there is insufficient information on which to base a rating 
  or that Standard & Poor’s does not rate a particular type of obligation as a matter of policy. 

Standard & Poor’s, Commercial Paper Ratings

A Standard & Poor’s Commercial Paper Rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days. Ratings are graded into four categories, ranging from “A” for the highest quality obligations to “D” for the lowest. Ratings are applicable to both taxable and tax-exempt commercial paper. The four categories are as follows:

A:  Issues assigned the highest rating are regarded as having the greatest capacity for timely payment. Issues 
  in this category are delineated with the numbers 1, 2, and 3 to indicate the relative degree of safety. 
 
A-1:  This designation indicates that the degree of safety regarding timely payment is either overwhelming or 
  very strong. Issues that possess overwhelming safety characteristics will be given a “+” designation. 

28  APPENDIX B  Principal Funds, Inc. 
    1-800-222-5852 


A-2:  Capacity for timely payment on issues with this designation is strong. However, the relative degree of 
  safety is not as high as for issues designated “A-1.” 
 
A-3:  Issues carrying this designation have a satisfactory capacity for timely payment. They are, however, 
  somewhat more vulnerable to the adverse effects of changes in circumstances than obligations carrying 
  the highest designations. 
 
B:  Issues rated “B” are regarded as having only an adequate capacity for timely payment. However, such 
  capacity may be damaged by changing conditions or short-term adversities. 
 
C:  This rating is assigned to short-term debt obligations with a doubtful capacity for payment. 
 
D:  This rating indicates that the issue is either in default or is expected to be in default upon maturity. 

The Commercial Paper Rating is not a recommendation to purchase or sell a security. The ratings are based on current information furnished to Standard & Poor’s by the issuer and obtained by Standard & Poor’s from other sources it considers reliable. The ratings may be changed, suspended, or withdrawn as a result of changes in or unavailability of, such information.

Standard & Poor’s rates notes with a maturity of less than three years as follows:

SP-1:  A very strong, or strong, capacity to pay principal and interest. Issues that possess overwhelming safety 
  characteristics will be given a “+” designation. 
SP-2:  A satisfactory capacity to pay principal and interest. 
SP-3:  A speculative capacity to pay principal and interest.

Main Strategies and Risks

Each Fund's investment objective is described in the summary description of each Fund. The Board of Directors may change a Fund's objective or the investment strategies without a shareholder vote if it determines such a change is in the best interests of the Fund. If there is a material change to the Fund's investment objective or investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that a Fund will meet its objective.

The summary of each Fund also describes each Fund's primary investment strategies (including the type or types of securities in which the Fund invests), any policy of the Fund to concentrate in securities of issuers in a particular industry or group of industries and the main risks associated with an investment in the Fund. A fuller discussion of risks appears later in the Prospectus under the caption "Certain Investment Strategies and Related Risks."

Each Fund may invest up to 100% of its assets in cash and cash equivalents for temporary defensive purposes in response to adverse market, economic, or political conditions as more fully described under the caption "Certain Investment Strategies and Related Risks-Temporary Defensive Measures."

Each Fund is designed to be a portion of an investor's portfolio. Neither of the Funds is intended to be a complete investment program. Investors should consider the risks of each Fund before making an investment and be prepared to maintain the investment during periods of adverse market conditions. The value of your investment in a Fund changes with the value of the investments held by that Fund. Many factors affect that value, and it is possible that you may lose money by investing in the Funds. There can be no assurance that either Fund will achieve its investment

Principal Funds, Inc.  RISK/RETURN SUMMARY  3

objective. An investment in a Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Factors that may adversely affect a particular Fund as a whole are called "principal risks." The principal risks of investing in the Funds are stated as to each Fund in the Fund's description. The Mortgage Securities Fund is also subject to underlying fund risk to the extent that a SAM Portfolio invests in the Fund. These risks are more fully explained in Appendix A to this prospectus.

Investment Results

A bar chart and a table are included with the description of the Fund that has annual returns for a full calendar year. They show the Fund's annual returns and its long-term performance. The chart shows how the Fund's performance has varied from year-to-year. The table compares the Fund's performance over time to that of:

·      a broad-based securities market index (An index measures the market price of a specific group of securities in a particular market or securities in a market sector. You cannot invest directly in an index. An index does not have an investment advisor and does not pay any commissions or expenses. If an index had expenses, its performance would be lower.) and
·      an average of mutual funds with a similar investment objective and management style (the averages used are prepared by independent statistical services).

Performance for classes of shares for periods prior to the date on which a Fund's oldest share class began operations (as indicated in the tables on the following pages) is based on the performance of the oldest share class of the Fund, adjusted to reflect the expenses of the share class shown. The adjustments result in performance (for the period prior to the effective date of the share class shown) that is no higher than the historical performance of the oldest share class.

Fees and Expenses

The annual operating expenses for each Fund are deducted from that Fund's assets. Each Fund's operating expenses are shown following each Fund’s description.

The examples following the expense tables for each Fund are intended to help you compare the cost of investing in either Fund with the cost of investing in other mutual funds.

NOTE:

·      No salesperson, dealer or other person is authorized to give information or make representations about a Fund other than those contained in this Prospectus. Information or representations not contained in this prospectus may not be relied upon as having been made by the Principal Funds, a Fund, Principal, any Sub-Advisor, PFD, or Princor.

GLOBAL DIVERSIFIED INCOME FUND 
 
Sub-Advisor(s):   Principal Global Investors, LLC, ("PGI”), Principal Real Estate Investors, LLC (“Principal-REI"), and
  Spectrum Asset Management, Inc. ("Spectrum”) 
 
Objective:  The Fund seeks consistent cash income through a diversified, yield-focused investment strategy. 
 
Investor Profile: The Fund may be an appropriate investment for investors seeking high cash returns, who are willing   
  to accept the risk associated with investing in equities and below-investment-grade fixed income 
  securities. 

Main Strategies and Risks

The Fund will invest a majority of its assets in fixed income asset classes, such as high yield bonds, preferred stocks, and emerging market debt securities, to provide incremental yields over a portfolio of government securities. In addition, the Fund will invest in equity securities of global companies principally engaged in the real estate industry and value equities of global companies to provide dividend yields and diversify fixed income-related risks in the Fund. The Fund seeks to provide yield by having each sub-advisor focus on those securities offering the best risk-adjusted yields within their respective asset class.

Approximately 35% of the Fund's assets will be invested in high yield and other income-producing securities including corporate bonds, corporate loan participations and assignments, convertible securities, credit default swaps, and securities of companies in bankruptcy proceedings or otherwise in the process of debt restructuring. The "high yield" securities in which the Fund invests are commonly known as "junk bonds" which are rated Ba or lower by Moody's Investor Service, Inc. ("Moody's") or BB or lower by Standard & Poor's Rating Service ("S&P"). These securities offer a higher yield than other, higher rated securities, but they carry a greater degree of risk and are considered speculative with respect to the issuer's ability to pay interest and to repay principal. It is expected that this portion of the Fund will have a weighted average quality rating of Ba3 as measured by Moody's or BB- by S&P. The average duration will be 2-3 years. PGI will manage this portion of the Fund.

Approximately 20% of the Fund's assets will be invested in equity securities of global companies principally engaged in the real estate industry ("real estate companies"). A real estate company has at least 50% of its assets, income or profits derived from products or services related to the real estate industry. Real estate companies include real estate investment trusts (“REITs”), REIT-like entities, and companies with substantial real estate holdings such as paper, lumber, hotel and entertainment companies as well as building supply manufacturers, mortgage lenders, and mortgage servicing companies. This portion of the Fund may invest in smaller capitalization companies. Principal-REI will manage this portion of the Fund.

Approximately 20% of the Fund's assets will be invested in preferred securities of U.S. companies primarily rated BBB or higher by S&P or Baa by Moody's or, if unrated, of comparable quality in the opinion of the Sub-Advisor. This portion of the Fund focuses primarily on the financial services, REITs, and utility industries. The rest of this portion of the Fund's assets may be invested in common stocks, debt securities, credit default swaps, and securities issued or guaranteed by the U.S. government or its agencies or instrumentalities. Spectrum will manage this portion of the Fund.

Approximately 15% of the Fund's assets will be invested in a diversified portfolio of value equity securities of companies located or operating in developed countries (including the United States) and emerging markets of the world to provide dividend yields. The equity securities will ordinarily be traded on a recognized foreign securities exchange or traded in a foreign over-the-counter market in the country where the issuer is principally based, but may also be traded in other countries including the United States. PGI will manage this portion of the Fund.

Approximately 10% of the Fund's assets will be invested in a diversified portfolio of bond issues issued primarily by governments, their agencies, local authorities and instrumentalities and corporate entities domiciled in or exercising the predominant part of their economic activities in emerging markets in Europe, Latin America, Asia, and the Middle East. The target duration for the portfolio will be 2-3 years. The targeted credit quality range will be Baa2 to B3 as measured by Moody's or BBB to B- by S&P. Securities denominated in local currency will be limited to 50% of the

Principal Funds, Inc.  RISK/RETURN SUMMARY  5 
www.principal.com     


portfolio in aggregate, and, typically, non-dollar currency exposure will not be hedged. PGI will manage this portion of the Fund.

Among the principal risks (as defined in Appendix A) of investing in the Fund are:

• High Yield Securities Risk  • Real Estate Securities Risk  • Equity Securities Risk 
• Active Trading Risk  • Value Stock Risk  • Exchange Rate Risk 
• Fixed-Income Risk  • Portfolio Duration Risk  • Foreign Securities Risk 
• Emerging Market Risk  • Derivatives Risk  • Securities Lending Risk 

The Fund is actively managed primarily against the Lehman Brothers U.S. Corporate High Yield - 2% Issuer Capped Index. Other indices are shown.

The Lehman Brothers U.S. Corporate High Yield - 2% Issuer Capped Index is an unmanaged index comprised of fixed rate, non-investment grade debt securities that are dollar denominated. The index limits the maximum exposure to any one issuer to 2%.

The Morgan Stanley Capital International (MSCI) World Value Index is a free float-adjusted market capitalization index that represents the value segment in global developed market equity performance.

The FTSE-EPRA (European Public Real Estate Association)-NAREIT (National Association of Real Estate Investment Trusts) Global Real Estate Securities Index is designed to track the performance of real estate companies and REITS worldwide.

The Merrill Lynch Fixed Rate Preferred Securities Index tracks the performance of fixed rate U.S. dollar denominated preferred securities issued in the US domestic market.

The JPMorgan Emerging Markets Bond Index (EMBI) Global includes U.S. dollar denominated Brady bonds, Eurobonds, and traded loans issued by sovereign and quasi-sovereign entities. The EMBI Global is a market-capitalization-weighted index.

Morningstar World Allocation Category. World-allocation portfolios seek to provide both capital appreciation and income by investing in three major areas: stocks, bonds, and cash. While these portfolios do explore the whole world, most of them focus on the U.S., Canada, Japan, and the larger markets in Europe.

MORTGAGE SECURITIES FUND 

Sub-Advisor(s): Edge Asset Management, Inc. (“Edge”)   
Objective:  The Fund seeks to provide a high level of current income consistent with safety and liquidity. 
Investor Profile:   The Fund may be appropriate for investors seeking diversification by investing in a fixed-income
  mutual fund. 

Main Strategies and Risks

The Fund invests primarily in mortgage-backed securities, including collateralized mortgage obligations. The Fund may also invest in dollar rolls, which may involve leverage.

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in mortgage-backed securities, including collateralized mortgage obligations, and in other obligations that are secured by mortgages or mortgage-backed securities, including repurchase agreements. The Fund may also invest in U.S. government securities. Certain issuers of U.S. government securities are sponsored or chartered by Congress but their securities are neither issued or guaranteed by the U.S. Treasury. The Fund may lend its portfolio securities to brokers, dealers, and other financial institutions. The Fund may use futures, options, swaps and derivative instruments to “hedge” or protect its portfolio from adverse movements in securities prices and interest rates.

The Fund invests in mortgage securities which represent good longer term value, taking into account potential returns, prepayment and credit risk as well as deal-structure where appropriate. The Fund also invests in Treasury and Agency securities primarily for duration and liquidity management purposes.

Among the principal risks (defined in Appendix A) of investing in the Fund are:

• Fixed-Income Securities Risk  • Derivatives Risk  • Prepayment Risk 
• Underlying Fund Risk  • Portfolio Duration Risk  • U.S. Government Securities Risk 
• U.S. Government Sponsored  • Securities Lending Risk   
       Securities Risk

     shares adjusted to reflect the fees and expenses of Class J shares. The adjustments result in performance for such periods that is no higher 
     than the historical performance on Class A shares. The Fund commenced operations after succeeding to the operations of another fund on 
     January 12, 2007. On March 1, 2004, the investment policies of the predecessor fund were modified. As a result, the Fund’s performance for

      place. 
 
(2)   After-tax returns are calculated using the historical highest individual federal marginal income-tax rates and do not reflect the impact of state and

The CDSC, if any, is determined by multiplying by 1.00% the lesser of the market value at the time of redemption or the initial purchase price of the shares sold.
 
  ·      The CDSC is not imposed on shares:
 
   ·      that were purchased pursuant to the Small Amount Force Out program (SAFO);
 
   ·      redeemed within 90 days after an account is re-registered due to a shareholder's death; or
 
   ·      redeemed due to a shareholder's disability (as defined in the Internal Revenue Code) provided the shares were purchased prior to the disability;
 
   ·      redeemed from retirement plans to satisfy minimum distribution rules under the Internal Revenue Code;
 
   ·      sold using a systematic withdrawal plan (up to 1% per month (measured cumulatively with respect to non- monthly plans) of the value of the Fund account at the time, and beginning on the date, the systematic withdrawal plan is established); or
 
   ·      that were redeemed from retirement plans to satisfy excess contribution rules under the Internal Revenue Code.
 
·      An excessive trading fee (see Frequent Purchases and Redemptions) of 1.00% is charged on redemptions or exchanges of $30,000 or more if the shares were purchased within 30 days of the redemption or exchanges. The fee does not apply to redemptions made: through a systematic withdrawal plan; due to a shareholder's death or disability (as defined in the Internal Revenue Code); or to satisfy minimum distribution rules imposed by the Internal Revenue Code. The fee is calculated as a percentage of market value of the shares redeemed or exchanged at the time of the shares' redemption.
 

Ongoing Fees

Ongoing fees reduce the value of each share. Because they are ongoing, they increase the cost of investing in the Funds.

Each of the Funds pays ongoing fees to Principal and others who provide services to the Fund. These fees include:

·      Management Fee - Through the Management Agreement with the Fund, Principal has agreed to provide investment advisory services and corporate administrative services to the Funds.
 
·      Distribution Fee - Each of the Funds has adopted a distribution plan under Rule 12b-1 of the Investment Company Act of 1940 for its Class J shares. Under the plan, the Class J shares of each Fund pays a distribution fee based on the average daily net asset value (NAV) of the Fund. These fees pay distribution and other expenses for the sale of Fund shares and for services provided to shareholders. Because they are ongoing fees, over time they will increase the cost of your investment and may cost you more than paying other types of sales charges.
 
·      Transfer Agent Fee - Principal Shareholder Services, Inc. ("PSS") has entered into a Transfer Agency Agreement with the Fund under which PSS provides transfer agent services to the Class J shares of the Fund. These services are currently provided at cost.
 

Class J shares of the Funds also pay expenses of registering and qualifying shares for sale, the cost of producing and distributing reports and prospectuses to Class J shareholders, the cost of shareholder meetings held solely for Class J shares, and other operating expenses of the Fund.

DISTRIBUTION PLANS AND INTERMEDIARY COMPENSATION

Each of the Funds has adopted a 12b-1 Plan for the Class J shares of the Fund. Under the 12b-1 Plans, each Fund may make payments from its assets attributable to the particular share class to the Fund's Distributor for distribution-related expenses and for providing services to shareholders of that share class. Because Rule 12b-1 fees are ongoing fees, over time they will increase the cost of an investment in the Funds and may cost more than paying other types of sales charges.

Princor and PFD are co-distributors for Class J shares of Principal Funds.

The maximum annual Rule 12b-1 distribution and/or service fee (as a percentage of average daily net assets) for each of the Funds is 0.45% .

The Distributors have contractually agreed to reduce the 12b-1 fee from 0.45% to 0.40% through December 31, 2008. The effect of this reduction will be to lower each Fund's total operating expenses and increase the Fund's total return. Payments under the 12b-1 plans will not automatically terminate for funds that are closed to new investors or to additional purchases by existing shareholders. The fund Board will determine whether to terminate, modify or leave unchanged the 12b-1 plan at the time the board directs the implementation of the closure of the fund.

The proceeds from the Rule 12b-1 fees paid by Class J shareholders, together with any applicable contingent deferred sales charge, are paid to the Distributors. The Distributors generally use these fees to finance any activity that is primarily intended to result in the sale of shares. Examples of such expenses include compensation to salespeople and selected dealers (including financing the commission paid to the dealer at the time of the sale), printing of prospectuses and statements of additional information and reports for other than existing shareholders, and preparing and conducting sales seminars. The Distributors also use the fees to provide services to existing shareholders, including without limitation, services such as furnishing information as to the status of shareholder accounts, responding to telephone and written inquiries of shareholders, and assisting shareholders with tax information.

Payments to Investment Representatives and Their Firms. Financial intermediaries market and sell shares of the Funds. These financial intermediaries receive compensation from the Distributors and their affiliates for selling shares of the Funds and/or providing services to the Funds' shareholders. Financial intermediaries may include, among others, broker-dealers, registered investment advisors, banks, trust companies, pension plan consultants, retirement plan administrators, and insurance companies. Investment Representatives who deal with investors on an individual basis are typically associated with a financial intermediary. The Distributors and their affiliates may fund this compensation from various sources, including any sales charge and/or Rule 12b-1 Plan fee that the shareholder or the Funds pay to the Distributors. Individual Investment Representatives may generally receive some or all of the amounts paid to the financial intermediary with which he or she is associated.

The Distributors and/or their affiliates provide services to and/or funding vehicles for retirement plans. The Distributors may pay a bonus or other consideration or incentive to dealers if a participant in such a retirement plan establishes a rollover individual retirement account with the assistance of the Distributors’ registered representative, if the dealer sold the funding vehicle the retirement plan utilizes or based on the dealer’s relationship to the retirement plan. The dealer may pay to its Investment Representatives some or all of the amounts the Distributors pay to the dealer.

The Distributors may, from time-to-time, at their expense or through use of amounts they receive from the Fund through a distribution plan adopted pursuant to Rule 12b-1 of the Investment Company Act of 1940, if applicable, pay a bonus or other consideration or incentive to dealers who have sold or may sell significant amounts of shares. Any such bonus or incentive program will not change the price paid by investors for the purchase of the Funds' shares or the amount that any particular Fund receives as the proceeds from such sales. In addition, the Distributors or their affiliates may provide financial support to dealers that sell shares of the Funds. This support is based primarily on the amount of sales of fund shares and/or total assets in the Funds. The amount of support may be affected by total sales; net sales; levels of redemptions; the dealers' support of, and participation in, the Distributors' marketing programs and the extent of a dealer's marketing programs relating to the Funds. Financial support to dealers may be made from payments from the Distributors' resources, from its retention of underwriting concessions and, in the case of share classes that have 12b-1 fees, from payments to the Distributors under such plans.

CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS

The Statement of Additional Information (SAI) contains additional information about investment strategies and their related risks.

Credit and Counterparty Risk

Each of the funds is subject to the risk that the issuer or guarantor of a fixed-income security or other obligation, the counterparty to a derivatives contract or repurchase agreement, or the borrower of a portfolio's securities will be unable or unwilling to make timely principal, interest, or settlement payments, or otherwise to honor its obligations.

Liquidity Risk

A fund is exposed to liquidity risk when trading volume, lack of a market maker, or legal restrictions impair the fund's ability to sell particular securities or close derivative positions at an advantageous price. Funds with principal investment strategies that involve securities of companies with smaller market capitalizations, foreign securities, derivatives, or securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk.

Management Risk

Each of the funds is actively managed by its investment advisor or sub-advisor(s). The performance of a fund that is actively managed will reflect in part the ability of the advisor or sub-advisor(s) to make investment decisions that are suited to achieving the fund's investment objective. If the advisor's or sub-advisor(s)' strategies do not perform as expected, a fund could underperform other mutual funds with similar investment objectives or lose money.

Securities and Investment Practices

Market Volatility. Equity securities include common stocks, preferred stocks, convertible securities, depositary receipts, rights, and warrants. Common stocks, the most familiar type, represent an equity (ownership) interest in a corporation. The value of a company's stock may fall as a result of factors directly relating to that company, such as decisions made by its management or lower demand for the company's products or services. A stock's value may also fall because of factors affecting not just the company, but also companies in the same industry or in a number of different industries, such as increases in production costs. The value of a company's stock may also be affected by changes in financial markets that are relatively unrelated to the company or its industry, such as changes in interest rates or currency exchange rates. In addition, a company's stock generally pays dividends only after the company invests in its own business and makes required payments to holders of its bonds and other debt. For this reason, the value of a company's stock will usually react more strongly than its bonds and other debt to actual or perceived changes in the company's financial condition or prospects. Stocks of smaller companies may be more vulnerable to adverse developments than those of larger companies.

Fixed-income securities include bonds and other debt instruments that are used by issuers to borrow money from investors. The issuer generally pays the investor a fixed, variable, or floating rate of interest. The amount borrowed must be repaid at maturity. Some debt securities, such as zero coupon bonds, do not pay current interest, but are sold at a discount from their face values.

Interest Rate Changes. Fixed-income securities are sensitive to changes in interest rates. In general, fixed-income security prices rise when interest rates fall and fall when interest rates rise. Longer term bonds and zero coupon bonds are generally more sensitive to interest rate changes.

Credit Risk. Fixed-income security prices are also affected by the credit quality of the issuer. Investment grade debt securities are medium and high quality securities. Some bonds, such as lower grade or "junk" bonds, may have speculative characteristics and may be particularly sensitive to economic conditions and the financial condition of the issuers.

Repurchase Agreements and Loaned Securities

Although not a principal investment strategy, each of the Funds may invest a portion of its assets in repurchase agreements. Repurchase agreements typically involve the purchase of debt securities from a financial institution such as a bank, savings and loan association, or broker-dealer. A repurchase agreement provides that the Fund sells back

14  CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS  Principal Funds, Inc. 
    1-800-222-5852 


to the seller and that the seller repurchases the underlying securities at a specified price on a specific date. Repurchase agreements may be viewed as loans by a Fund collateralized by the underlying securities. This arrangement results in a fixed rate of return that is not subject to market fluctuation while the Fund holds the security. In the event of a default or bankruptcy by a selling financial institution, the affected Fund bears a risk of loss. To minimize such risks, the Fund enters into repurchase agreements only with parties a Sub-Advisor deems creditworthy (those that are large, well-capitalized and well-established financial institutions). In addition, the value of the securities collateralizing the repurchase agreement is, and during the entire term of the repurchase agreement remains, at least equal to the repurchase price, including accrued interest.

Each of the Funds may lend its portfolio securities to unaffiliated broker-dealers and other unaffiliated qualified financial institutions. These transactions involve a risk of loss to the Fund if the counterparty should fail to return such securities to the Fund upon demand or if the counterparty's collateral invested by the Fund declines in value as a result of the investment losses.

Bank Loans (also known as Senior Floating Rate Interests)

The Global Diversified Income Fund invests in bank loans. Bank loans hold the most senior position in the capital structure of a business entity (the "Borrower"), are typically secured by specific collateral, and have a claim on the assets and/or stock of the Borrower that is senior to that held by subordinated debtholders and stockholders of the Borrower. Bank loans are typically structured and administered by a financial institution that acts as the agent of the lenders participating in the bank loan. Bank loans are rated below-investment-grade, which means they are more likely to default than investment-grade loans. A default could lead to non-payment of income which would result in a reduction of income to the fund and there can be no assurance that the liquidation of any collateral would satisfy the Borrower's obligation in the event of non-payment of scheduled interest or principal payments, or that such collateral could be readily liquidated.

Bank loans pay interest at rates which are periodically reset by reference to a base lending rate plus a spread. These base lending rates are generally the prime rate offered by a designated U.S. bank or the London InterBank Offered Rate (LIBOR) or the prime rate offered by one or more major United States banks.

Bank loans generally are subject to mandatory and/or optional prepayment. Because of these mandatory prepayment conditions and because there may be significant economic incentive for the Borrower to repay, prepayments of senior floating rate interests may occur.

Currency Contracts

A forward currency contract involves a privately negotiated obligation to purchase or sell a specific currency at a future date at a price set in the contract. A Fund will not hedge currency exposure to an extent greater than the aggregate market value of the securities held or to be purchased by the Fund (denominated or generally quoted or currently convertible into the currency).

Hedging is a technique used in an attempt to reduce risk. If a Fund's Sub-Advisor hedges market conditions incorrectly or employs a strategy that does not correlate well with the Fund's investment, these techniques could result in a loss. These techniques may increase the volatility of a Fund and may involve a small investment of cash relative to the magnitude of the risk assumed. In addition, these techniques could result in a loss if the other party to the transaction does not perform as promised. There is also a risk of government action through exchange controls that would restrict the ability of the Fund to deliver or receive currency.

Forward Commitments

Although not a principal investment strategy, the Global Diversified Income Fund may enter into forward commitment agreements. These agreements call for the Fund to purchase or sell a security on a future date at a fixed price. That Fund may also enter into contracts to sell its investments either on demand or at a specific interval.

Warrants

The Global Diversified Income Fund may invest in warrants though it will not use such investments as a principal investment strategy. A warrant is a certificate granting its owner the right to purchase securities from the issuer at a specified price, normally higher than the current market price.

Principal Funds, Inc.  CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS  15

High Yield Securities

The Global Diversified Income Fund may invest in debt securities rated BB or lower by S&P or Ba or lower by Moody's or, if not rated, determined to be of equivalent quality by Principal or the Sub-Advisor. Such securities are sometimes referred to as high yield or "junk bonds" and are considered speculative.

Investment in high yield bonds involves special risks in addition to the risks associated with investment in highly rated debt securities. High yield bonds may be regarded as predominantly speculative with respect to the issuer's continuing ability to meet principal and interest payments. Moreover, such securities may, under certain circumstances, be less liquid than higher rated debt securities.

Analysis of the creditworthiness of issuers of high yield securities may be more complex than for issuers of higher quality debt securities. The ability of a Fund to achieve its investment objective may, to the extent of its investment in high yield bonds, be more dependent on such credit analysis than would be the case if the Fund were investing in higher quality bonds.

High yield bonds may be more susceptible to real or perceived adverse economic and competitive industry conditions than higher-grade bonds. The prices of high yield bonds have been found to be less sensitive to interest rate changes than more highly rated investments, but more sensitive to adverse economic downturns or individual corporate developments. If the issuer of high yield bonds defaults, a Fund may incur additional expenses to seek recovery.

The secondary market on which high yield bonds are traded may be less liquid than the market for higher- grade bonds. Less liquidity in the secondary trading market could adversely affect the price at which a Fund could sell a high yield bond and could adversely affect and cause large fluctuations in the daily price of the Fund's shares. Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the value and liquidity of high yield bonds, especially in a thinly traded market.

The use of credit ratings for evaluating high yield bonds also involves certain risks. For example, credit ratings evaluate the safety of principal and interest payments, not the market value risk of high yield bonds. Also, credit rating agencies may fail to change credit ratings in a timely manner to reflect subsequent events. If a credit rating agency changes the rating of a portfolio security held by a Fund, the Fund may retain the security if the Sub-Advisor thinks it is in the best interest of shareholders.

Real Estate Investment Trusts

The Global Diversified Income Fund typically invests a significant portion of its net assets in REITs. REITs involve certain unique risks in addition to those risks associated with investing in the real estate industry in general (such as possible declines in the value of real estate, lack of availability of mortgage funds, or extended vacancies of property). Equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of any credit extended. REITs are dependent upon management skills, are not diversified, and are subject to heavy cash flow dependency, risks of default by borrowers, and self-liquidation. As an investor in a REIT, the Fund will be subject to the REIT's expenses, including management fees, and will remain subject to the Fund's advisory fees with respect to the assets so invested. REITs are also subject to the possibilities of failing to qualify for the special tax treatment accorded REITs under the Internal Revenue Code, and failing to maintain their exemptions from registration under the 1940 Act.

Investment in REITs involves risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume, and may be subject to more abrupt or erratic price movements than larger company securities.

Initial Public Offerings ("IPOs")

The Global Diversified Income Fund may invest in IPOs. An IPO is a company's first offering of stock to the public. IPO risk is that the market value of IPO shares will fluctuate considerably due to factors such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer. The purchase of IPO shares may involve high transaction costs. IPO shares are subject to market risk and liquidity risk. In addition, the market for IPO shares can be speculative and/or inactive for extended periods of time. The limited number of shares available for trading in some IPOs may make it more difficult for a Fund to buy or sell

16  CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS  Principal Funds, Inc. 
    1-800-222-5852 


significant amounts of shares without an unfavorable impact on prevailing prices. Investors in IPO shares can be affected by substantial dilution in the value of their shares by sales of additional shares and by concentration of control in existing management and principal shareholders.

When the Fund's asset base is small, a significant portion of the Fund's performance could be attributable to investments in IPOs because such investments would have a magnified impact on the Fund. As the Fund's assets grow, the effect of the Fund's investments in IPOs on the Fund's performance probably will decline, which could reduce the Fund's performance. Because of the price volatility of IPO shares, a Fund may choose to hold IPO shares for a very short period of time. This may increase the turnover of the Fund's portfolio and lead to increased expenses to the Fund, such as commissions and transaction costs. By selling IPO shares, the Fund may realize taxable gains it will subsequently distribute to shareholders.

Derivatives

To the extent permitted by its investment objectives and policies, each of the Funds may invest in securities that are commonly referred to as derivative securities. Generally, a derivative is a financial arrangement, the value of which is derived from, or based on, a traditional security, asset, or market index. Certain derivative securities are described more accurately as index/structured securities. Index/structured securities are derivative securities whose value or performance is linked to other equity securities (such as depositary receipts), currencies, interest rates, indices, or other financial indicators (reference indices).

Some derivatives, such as mortgage-related and other asset-backed securities, are in many respects like any other investment, although they may be more volatile or less liquid than more traditional debt securities.

There are many different types of derivatives and many different ways to use them. Futures and options are commonly used for traditional hedging purposes to attempt to protect a Fund from exposure to changing interest rates, securities prices, or currency exchange rates and for cash management purposes as a low-cost method of gaining exposure to a particular securities market without investing directly in those securities. The Funds may enter into put or call options, futures contracts, options on futures contracts, over-the-counter swap contracts (e.g., interest rate swaps, total return swaps, and credit default swaps), and forward currency contracts for both hedging and non-hedging purposes.

Generally, neither Fund may invest in a derivative security unless the reference index or the instrument to which it relates is an eligible investment for the Fund or the reference currency relates to an eligible investment for the Fund.

The return on a derivative security may increase or decrease, depending upon changes in the reference index or instrument to which it relates. The risks associated with derivative investments include:

·      the risk that the underlying security, interest rate, market index, or other financial asset will not move in the direction the Sub-Advisor anticipated;
·      the possibility that there may be no liquid secondary market which may make it difficult or impossible to close out a position when desired;
·      the risk that adverse price movements in an instrument can result in a loss substantially greater than a Fund's initial investment; and
·      the counterparty may fail to perform its obligations.

Exchange Traded Funds (ETFs)

These are a type of index or actively managed fund bought and sold on a securities exchange. An ETF trades like common stock. Shares in an index ETF represent an interest in a fixed portfolio of securities designed to track a particular market index. The Funds could purchase shares issued by an ETF to temporarily gain exposure to a portion of the U.S. or a foreign market while awaiting purchase of underlying securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities they are designed to track, although ETFs have management fees that increase their costs.

Convertible Securities

Convertible securities are fixed-income securities that a Fund has the right to exchange for equity securities at a specified conversion price. The option allows the Fund to realize additional returns if the market price of the equity securities exceeds the conversion price. For example, the Fund may hold fixed-income securities that are convertible

Principal Funds, Inc.  CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS  17 
www.principal.com     


into shares of common stock at a conversion price of $10 per share. If the market value of the shares of common stock reached $12, the Fund could realize an additional $2 per share by converting its fixed-income securities.

Convertible securities have lower yields than comparable fixed-income securities. In addition, at the time a convertible security is issued the conversion price exceeds the market value of the underlying equity securities. Thus, convertible securities may provide lower returns than non-convertible fixed-income securities or equity securities depending upon changes in the price of the underlying equity securities. However, convertible securities permit the Fund to realize some of the potential appreciation of the underlying equity securities with less risk of losing its initial investment.

The Funds treat convertible securities as both fixed-income and equity securities for purposes of investment policies and limitations because of their unique characteristics. The Funds may invest in convertible securities without regard to their ratings.

Foreign Investing

As a principal investment strategy, the Global Diversified Income Fund may invest Fund assets in securities of foreign companies. The Mortgage Securities Fund may invest in securities of foreign companies but not as a principal investment strategy. For the purpose of this restriction, foreign companies are:

·      companies with their principal place of business or principal office outside the U.S. or
·      companies for which the principal securities trading market is outside the U.S.

Foreign companies may not be subject to the same uniform accounting, auditing, and financial reporting practices as are required of U.S. companies. In addition, there may be less publicly available information about a foreign company than about a U.S. company. Securities of many foreign companies are less liquid and more volatile than securities of comparable U.S. companies. Commissions on foreign securities exchanges may be generally higher than those on U.S. exchanges.

Foreign markets also have different clearance and settlement procedures than those in U.S. markets. In certain markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct these transactions. Delays in settlement could result in temporary periods when a portion of Fund assets is not invested and earning no return. If a Fund is unable to make intended security purchases due to settlement problems, the Fund may miss attractive investment opportunities. In addition, a Fund may incur a loss as a result of a decline in the value of its portfolio if it is unable to sell a security.

With respect to certain foreign countries, there is the possibility of expropriation or confiscatory taxation, political or social instability, or diplomatic developments that could affect a Fund's investments in those countries. In addition, a Fund may also suffer losses due to nationalization, expropriation or differing accounting practices and treatments. Investments in foreign securities are subject to laws of the foreign country that may limit the amount and types of foreign investments. Changes of governments or of economic or monetary policies, in the U.S. or abroad, changes in dealings between nations, or currency convertibility or exchange rates could result in investment losses for a Fund. Finally, even though certain currencies may be convertible into U.S. dollars, the conversion rates may be artificial relative to the actual market values and may be unfavorable to Fund investors.

Foreign securities are often traded with less frequency and volume, and therefore may have greater price volatility, than is the case with many U.S. securities. Brokerage commissions, custodial services, and other costs relating to investment in foreign countries are generally more expensive than in the U.S. Though the Funds intend to acquire the securities of foreign issuers where there are public trading markets, economic or political turmoil in a country in which a Fund has a significant portion of its assets or deterioration of the relationship between the U.S. and a foreign country may negatively impact the liquidity of a Fund's portfolio. A Fund may have difficulty meeting a large number of redemption requests. Furthermore, there may be difficulties in obtaining or enforcing judgments against foreign issuers.

A Fund may choose to invest in a foreign company by purchasing depositary receipts. Depositary receipts are certificates of ownership of shares in a foreign-based issuer held by a bank or other financial institution. They are alternatives to purchasing the underlying security but are subject to the foreign securities to which they relate.

18  CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS  Principal Funds, Inc. 
    1-800-222-5852 


Investments in companies of developing (also called “emerging”) countries may be subject to higher risks than investments in companies in more developed countries. These risks include:

·      increased social, political, and economic instability;
·      a smaller market for these securities and low or nonexistent volume of trading that results in a lack of liquidity and in greater price volatility;
·      lack of publicly available information, including reports of payments of dividends or interest on outstanding securities;
·      foreign government policies that may restrict opportunities, including restrictions on investment in issuers or industries deemed sensitive to national interests;
·      relatively new capital market structure or market-oriented economy;
·      the possibility that recent favorable economic developments may be slowed or reversed by unanticipated political or social events in these countries;
·      restrictions that may make it difficult or impossible for the Fund to vote proxies, exercise shareholder rights, pursue legal remedies, and obtain judgments in foreign courts; and
·      possible losses through the holding of securities in domestic and foreign custodial banks and depositories.

In addition, many developing countries have experienced substantial and, in some periods, extremely high rates of inflation for many years. Inflation and rapid fluctuations in inflation rates have had and may continue to have negative effects on the economies and securities markets of those countries.

Repatriation of investment income, capital and proceeds of sales by foreign investors may require governmental registration and/or approval in some developing countries. A Fund could be adversely affected by delays in or a refusal to grant any required governmental registration or approval for repatriation.

Further, the economies of developing countries generally are heavily dependent upon international trade and, accordingly, have been and may continue to be adversely affected by trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which they trade.

Small and Medium Capitalization Companies

The Global Diversified Income Fund may hold securities of small and medium capitalization companies but not as a principal investment strategy. The international funds invest in the securities of foreign companies without regard to the market capitalizations of those companies. Market capitalization is defined as total current market value of a company's outstanding common stock. Investments in companies with smaller market capitalizations may involve greater risks and price volatility (wide, rapid fluctuations) than investments in larger, more mature companies. Small companies may be less significant within their industries and may be at a competitive disadvantage relative to their larger competitors. While smaller companies may be subject to these additional risks, they may also realize more substantial growth than larger or more established companies.

Smaller companies may be less mature than larger companies. At this earlier stage of development, the companies may have limited product lines, reduced market liquidity for their shares, limited financial resources or less depth in management than larger or more established companies. Unseasoned issuers are companies with a record of less than three years continuous operation, including the operation of predecessors and parents. Unseasoned issuers by their nature have only a limited operating history that can be used for evaluating the company's growth prospects. As a result, investment decisions for these securities may place a greater emphasis on current or planned product lines and the reputation and experience of the company's management and less emphasis on fundamental valuation factors than would be the case for more mature growth companies.

Temporary Defensive Measures

From time to time, as part of its investment strategy, each Fund may invest without limit in cash and cash equivalents for temporary defensive purposes in response to adverse market, economic or political conditions. To the extent that the Fund is in a defensive position, it may lose the benefit of upswings and limit its ability to meet its investment objective. For this purpose, cash equivalents include: bank notes, bank certificates of deposit, bankers' acceptances, repurchase agreements, commercial paper, and commercial paper master notes which are floating rate debt

Principal Funds, Inc.  CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS  19 
www.principal.com     


instruments without a fixed maturity. In addition, a Fund may purchase U.S. government securities, preferred stocks and debt securities, whether or not convertible into or carrying rights for common stock.

There is no limit on the extent to which the Funds may take temporary defensive measures. In taking such measures, the Fund may fail to achieve its investment objective.

Portfolio Turnover

"Portfolio Turnover" is the term used in the industry for measuring the amount of trading that occurs in a Fund's portfolio during the year. For example, a 100% turnover rate means that on average every security in the portfolio has been replaced once during the year. Funds that engage in active trading may have high portfolio turnover.

Funds with high turnover rates (more than 100%) often have higher transaction costs (that are paid by the Fund) which may have an adverse impact on Fund performance and may generate short-term capital gains (on which taxes may be imposed even if no shares of the Fund are sold during the year).

Please consider all the factors when you compare the turnover rates of different funds. A fund with consistently higher total returns and higher turnover rates than another fund may actually be achieving better performance precisely because the managers are active traders.

Duties of Principal and Sub-Advisors

Principal or the Sub-Advisor provides the Directors of the Fund with a recommended investment program. The program must be consistent with the Fund's investment objective and policies. Within the scope of the approved investment program, the Sub-Advisor advises the Fund on its investment policy and determines which securities are bought or sold, and in what amounts.

One of these Funds has multiple Sub-Advisors. For this Fund, Principal determines the portion of the Fund's assets each Sub-Advisor will manage and may, from time-to-time, reallocate Fund assets among the Sub-Advisors. The decision to do so may be based on a variety of factors, including but not limited to: the investment capacity of each Sub-Advisor, portfolio diversification, volume of net cash flows, fund liquidity, investment performance, investment strategies, changes in each Sub-Advisor's firm or investment professionals or changes in the number of Sub-Advisors. Ordinarily, reallocations of Fund assets among Sub-Advisors will generally occur as a Sub-Advisor liquidates assets in the normal course of portfolio management and with net new cash flows; however, at times, existing Fund assets may be reallocated among Sub-Advisors.

Fees Paid to Principal

The Fund pays Principal a fee for its services, which includes any fee Principal pays to the Sub-Advisor. The fee the Mortgage Securities Fund paid (as a percentage of the average daily net assets) for the fiscal year ended October 31, 2007 was 0.50% .

The fee the Global Diversified Income Fund will pay (as a percentage of the average daily net assets) is:

  0.80% on the first $500 million
0.78% on the next $500 million
0.76% on the next $500 million
0.75% on the next $500 million
0.73% on the next $1.0 billion
0.70% on assets over $3.0 billion

A discussion regarding the basis for the Board of Directors approving the management agreement with Principal and the sub-advisory agreements with these Sub-Advisors will be included in the annual report to shareholders for the fiscal year ended October 31, 2008, which will be available 60 days after that date. A discussion regarding the basis for the Board of Directors approving the management agreement with Principal and the sub-advisory agreement with Edge was included in the annual report to shareholders for the fiscal year ended October 31, 2007.

Under an order received from the SEC, the Fund and Principal, may enter into and materially amend agreements with Sub-Advisors, other than those affiliated with Principal, without obtaining shareholder approval. For any Fund that is relying on that order, Principal may, without obtaining shareholder approval:

·      hire one or more Sub-Advisors;
·      change Sub-Advisors; and
·      reallocate management fees between itself and Sub-Advisors.

Principal has ultimate responsibility for the investment performance of each Fund that utilizes a Sub-Advisor due to its responsibility to oversee Sub-Advisors and recommend their hiring, termination, and replacement. No Fund will rely on

24  MANAGEMENT OF THE FUNDS  Principal Funds, Inc. 
    1-800-222-5852 


the order until it receives approval from its shareholders or, in the case of a new Fund, the Fund's sole initial shareholder before the Fund is available to the other purchasers, and the Fund states in its prospectus that it intends to rely on the order.

The shareholders of each of the Funds have approved the Fund's reliance on the order; however, these Funds do not intend to rely on the order.

PRICING OF FUND SHARES

Each Fund's shares are bought and sold at the current share price. The share price of each class of each Fund is calculated each day the New York Stock Exchange ("NYSE") is open (shares are not priced on the days on which the NYSE is closed for trading, generally New Year's Day, Martin Luther King, Jr. Day, Washington's Birthday/Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas). The share price is determined as of the close of business of the NYSE (normally 3:00 p.m. Central Time). When an order to buy or sell shares is received, the share price used to fill the order is the next price calculated after the order is received in good order by us at our transaction processing center in Canton, Massachusetts. In order for us to process your purchase order on the day it is received, we must receive the order (with complete information):

·      on a day that the NYSE is open and
·      prior to the close of trading on the NYSE (normally 3 p.m. Central Time).

Orders received after the close of the NYSE or on days that the NYSE is not open will be processed on the next day that the NYSE is open for normal trading.

If we receive an application or purchase request for a new mutual fund account or subsequent purchase into an existing account that is accompanied by a check and the application or purchase request does not contain complete information, we may hold the application (and check) for up to two business days while we attempt to obtain the necessary information. If we receive the necessary information within two business days, we will process the order using the next share price calculated. If we do not receive the information within two business days, the application and check will be returned to you.

For these Funds, the share price is calculated by:

·      taking the current market value of the total assets of the Fund
·      subtracting liabilities of the Fund
·      dividing the remainder proportionately into the classes of the Fund
·      subtracting the liability of each class
·      dividing the remainder by the total number of shares owned in that class.

NOTES:

·      If market quotations are not readily available for a security owned by a Fund, its fair value is determined using a policy adopted by the Directors. Fair valuation pricing is subjective and creates the possibility that the fair value determined for a security may differ materially from the value that could be realized upon the sale of the security.
·     

A Fund's securities may be traded on foreign securities markets that generally complete trading at various times during the day prior to the close of the NYSE. Generally, the values of foreign securities used in computing a Fund's NAV are the market quotations as of the close of the foreign market. Foreign securities and currencies are also converted to U.S. dollars using the exchange rate in effect at the close of the NYSE. Occasionally, events affecting the value of foreign securities occur when the foreign market is closed and the NYSE is open. The Fund has adopted policies and procedures to "fair value" some or all securities held by a Fund if significant events occur after the close of the market on which the foreign securities are traded but before the Fund's NAV is calculated.

 

 

Significant events can be specific to a single security or can include events that affect a particular foreign market or markets. A significant event can also include a general market movement in the U.S. securities markets. If Principal believes that the market value of any or all of the foreign securities is materially affected by such an event, the securities will be valued, and the Fund's NAV will be calculated, using the policy adopted by the Fund. These fair valuation procedures are intended to discourage shareholders from investing in the Fund for the purpose of engaging in market timing or arbitrage transactions.

 
  The trading of foreign securities generally or in a particular country or countries may not take place on all days the NYSE is open, or may trade on days the NYSE is closed. Thus, the value of the foreign securities held by the Fund may change on days when shareholders are unable to purchase or redeem shares.
 
·      Certain securities issued by companies in emerging market countries may have more than one quoted valuation at any point in time. These may be referred to as local price and premium price. The premium price is often a
 
26  PRICING OF FUND SHARES  Principal Funds, Inc. 
    1-800-222-5852 


negotiated price that may not consistently represent a price at which a specific transaction can be effected. The Fund has a policy to value such securities at a price at which the Sub-Advisor expects the securities may be sold.

PURCHASE OF FUND SHARES

Fill out the Principal Funds (or the IRA, SEP or SIMPLE) application completely. You must include:

·      the name you want to appear on the account;
·      the Principal Funds in which you want to invest;
·      the amount of the investment;
·      your Social Security number; and
·      other required information.

The Fund requires a minimum initial investment of $1,000. Subsequent investment minimums are $100.

·      Principal Funds may reject or cancel any purchase orders for any reason. For example, Principal Funds does not intend to permit market timing because short-term or other excessive trading into and out of the Funds may harm performance by disrupting portfolio management strategies and by increasing expenses. Accordingly, Principal Funds may reject any purchase orders from market timers or investors that, in Principal's opinion, may be disruptive to the Funds. For these purposes, Principal may consider an investor's trading history in the Funds or other Funds sponsored by Principal Life and accounts under common ownership or control. Principal may recommend to the Board, and the Board may elect, to close certain funds to new and existing investors.
·      If you are making an initial purchase of Principal Investors Funds of $1,000,000 or more and have selected Class J shares, the purchase will be of Class A shares of the Fund(s) you have selected.
·      The minimum investment applies on a per Fund level, not on the total investment being made.

To eliminate the need for safekeeping, Principal Funds will not issue certificates for shares. Principal Funds may periodically close to new purchases of shares or refuse any order to buy shares if Principal determines that doing so would be in the best interests of Principal Funds and its shareholders.

Accounts with foreign addresses cannot be established. If an existing shareholder with a U.S. address moves to a foreign location and updates the address on the shareholder's account, we are unable to process any purchases or exchanges on that account.

Payments are to be made via personal or financial institution check (for example, a bank or cashier’s check). We reserve the right to refuse any payment that we feel presents a fraud or money laundering risk. Examples of the types of payments we will not accept are cash, money orders, travelers’ checks, credit card checks, and foreign checks.

Payment. Payment for shares of Principal Funds purchased as a direct rollover IRA is made by the retirement plan trustees. Payment for other shares is generally made via personal check or cashiers check. We consider your purchase of Fund shares by check to be your authorization to make an automated clearing house ("ACH") debit entry to your account. Shares purchased by check may be sold only after the check has cleared your bank, which may take up to 7 calendar days.

Your Investment Representative can help you buy shares of Principal Funds by mail, through bank wire, direct deposit or Automatic Investment Plan. Contact Principal Funds at 1-800-222-5852 to obtain bank wire instructions. No wires are accepted on days when the NYSE is closed or when the Federal Reserve is closed (because the bank that would receive your wire is closed).

Direct Deposit

Your Investment Representative can help you make a Direct Deposit from your paycheck (if your employer approves) or from a government allotment. Direct Deposit allows you to deposit automatically all or part of your paycheck (or government allotment) to your Principal Funds account(s). You will receive a Direct Deposit Authorization Form to give to your employer or the governmental agency (either of which may charge a fee for this service). Shares will be

purchased on the day the ACH notification is received by Wells Fargo, N.A. On days when the NYSE is closed, but the bank receiving the ACH notification is open, your purchase will be priced at the next calculated share price.

Automatic Investment Plan

Your Investment Representative can help you establish an Automatic Investment Plan. You may make regular monthly investments with automatic deductions from your bank or other financial institution account. You select the day of the month the deduction is to be made. If that date is a non-trading day, we will process the deduction on the next trading day. If the next trading day falls in the next month or year, we will process the deduction on the day prior to your selected day. The minimum initial investment is waived if you set up an Automatic Investment Plan when you open your account. Minimum monthly purchase is $100 per Fund.

REDEMPTION OF FUND SHARES

After you place a sell order in proper form, shares are sold using the next share price calculated. The amount you receive will be reduced by any applicable CDSC or excessive trading fee. There is no additional charge for a sale of shares; however, you will be charged a $10 wire fee if you have the sale proceeds wired to your bank. Generally, the sale proceeds are sent out on the next business day* after the sell order has been placed. It may take additional business days for your financial institution to post this payment to your account at that financial institution. At your request, the check will be sent overnight (a $15 overnight fee will be deducted from your account unless other arrangements are made). A Fund can only sell shares after your check making the Fund investment has cleared your bank, which may take up to 7 calendar days. A sell order from one owner is binding on all joint owners.

* a day when the NYSE is open for normal business

Distributions from IRA, SEP, SIMPLE, and SAR-SEP accounts may be taken as:

·      lump sum of the entire interest in the account,
·      partial interest in the account, or
·      periodic payments of either a fixed amount or an amount based on certain life expectancy calculations.

Tax penalties may apply to distributions before the participant reaches age 59 1/2.

·      payable to all owners on the account (as shown in the account registration) and
·      mailed to the address on the account (if not changed within last 30 days) or previously authorized bank account.

If the selected date is not a trading day, the sale will take place on the preceding trading day (if that day falls in the month or year prior to your selected date, the transaction will take place on the next trading day after your selected date). If telephone privileges apply to the account, you may change the date or amount by telephoning us.

Sales made under your systematic withdrawal plan will reduce and may eventually exhaust your account. The Funds do not normally accept purchase payments while a systematic withdrawal plan is in effect (unless the purchase represents a substantial addition to your account).

·      An exchange fee is imposed on exchanges of $30,000 or more if the exchanged shares were purchased within 30 days of the date of the exchange.

General

• An exchange by any joint owner is binding on all joint owners.

       established. The new account has the same owner(s), dividend and capital gain options and dealer of record as the 
       account from which the shares are being exchanged. 
• All exchanges are subject to the minimum investment and eligibility requirements of the Fund being acquired. 
• You may acquire shares of a Fund only if its shares are legally offered in your state of residence. 
• For an exchange to be effective the day we receive your instruction, we must receive the instruction in good order 
       at our transaction processing center in Canton, Massachusetts before the close of normal trading on the NYSE 
       (generally 3 p.m. Central Time). 

30  EXCHANGE OF FUND SHARES  Principal Funds, Inc. 
    1-800-222-5852 


When money is exchanged or transferred from one account registration or tax identification number to another, the account holder is relinquishing his or her rights to the money. Therefore exchanges and transfers can only be accepted by telephone if the exchange (transfer) is between:

·      accounts with identical ownership,
·      an account with a single owner to one with joint ownership if the owner of the single owner account is also an owner of the account with joint ownership,
·      a single owner to a Uniform Transfer to Minors Act ("UTMA") account if the owner of the single owner account is also the custodian on the UTMA account, or
·      a single or jointly owned account to an IRA account to fund the yearly IRA contribution of the owner (or one of the owners in the case of a jointly owned account).

The exchange is treated as a sale of shares for federal (and state) income tax purposes and may result in a capital gain or loss. Income tax rules regarding the calculation of cost basis may make it undesirable in certain circumstances to exchange shares within 90 days of their purchase.

Fund shares used to fund an employee benefit plan may be exchanged only for shares of other Principal Funds available to employee benefit plans. Such an exchange must be made by following the procedures provided in the employee benefit plan and the written service agreement.

Excessive Trading fee. An excessive trading fee may apply to exchanges made within 30 days of purchase as described in "Frequent Purchases and Redemptions." If excessive trading is deemed to be occurring, additional restrictive actions may be taken, as described below.

FREQUENT PURCHASES AND REDEMPTIONS

The Funds are not designed for, and do not knowingly accommodate, frequent purchases and redemptions of fund shares by investors. If you intend to trade frequently and/or use market timing investment strategies, you should not purchase these Funds.

Frequent purchases and redemptions pose a risk to Principal Funds because they may:

·      Disrupt the management of Principal Funds by:
  ·      forcing the Funds to hold short-term (liquid) assets rather than investing for long term growth, which results in lost investment opportunities for Principal Funds; and
  ·      causing unplanned portfolio turnover;
·      Hurt the portfolio performance of Principal Funds; and
·      Increase expenses of Principal Funds due to:
  ·      increased broker-dealer commissions and
  ·      increased recordkeeping and related costs.

Certain Funds may be at greater risk of harm due to frequent purchases and redemptions. For example, those Funds that invest in foreign securities may appeal to investors attempting to take advantage of time-zone arbitrage.

Principal Funds has adopted procedures to "fair value" foreign securities under certain circumstances, which are intended, in part, to discourage excessive trading of shares of the Funds. The Board of Directors of the Fund has also adopted policies and procedures with respect to frequent purchases and redemptions of shares of the Funds. The Funds monitor trading activity to identify and take action against abuses. While our policies and procedures are designed to identify and protect against abusive trading practices, there can be no certainty that we will identify and prevent abusive trading in all instances. If we are not able to identify such excessive trading practices, the Funds may be negatively impacted and may cause investors to suffer the harms described. The potential negative impact and harms of undetected excessive trading in shares of the underlying Funds in which the Strategic Asset Management Funds invest could flow through to the Strategic Asset Management Funds as they would for any Fund shareholder. When we do identify abusive trading, we will apply our policies and procedures in a fair and uniform manner. If we are not able to identify such abusive trading practices, the abuses described above may negatively impact the Funds.

Currently the Funds impose an excessive trading fee on redemptions or exchanges of $30,000 or more of a Fund's Class J shares redeemed within 30 days after they are purchased. The fee does not apply to redemptions or exchanges made pursuant to an Automatic Exchange Election or Systematic Withdrawal Plan through an Automatic Exchange Election or a Systematic Withdrawal Plan; due to a shareholder's death or disability (as defined in the Internal Revenue Code); to satisfy minimum distribution rules imposed by the Internal Revenue Code; or where the application of the fee would cause a Fund to fail to be considered a "qualified default investment alternative" under the Employee Retirement Income Security Act of 1976, as amended, and the rules and regulations thereunder. The fee is equal to 1.00% of the total redemption or exchange amount. The fee is paid to the Funds and is intended to offset the trading costs, market impact, and other costs associated with short-term money movement in and out of the Funds.

The imposition of the excessive trading fee may be waived if an intermediary, such as a retirement plan recordkeeper, through which Fund shares are made available to shareholders is unable or unwilling to impose the fee, but is able to implement other procedures the Fund believes are reasonably designed to prevent excessive trading in Fund shares.

In addition, if a Fund deems frequent trading and redemptions to be occurring, action will be taken that may include, but is not limited to:

·      Increasing the excessive trading fee to 2%,
·      Increasing the excessive trading fee period from 30 days to as much as 90 days,
·      Applying the excessive trading fee to redemptions or exchanges of less than $30,000,
·      Limiting the number of permissible exchanges available to shareholders identified as "excessive traders,"
·      Limit exchange requests to be in writing and submitted through the United States Postal Service (in which case, requests for exchanges by fax, telephone or internet will not be accepted), and
·      Taking such other action as directed by the Fund.

    1-800-222-5852 


The Funds have reserved the right to accept or reject, without prior written notice, any exchange requests. In some instances, an exchange may be completed prior to a determination of abusive trading. In those instances, we will reverse the exchange and return the account holdings to the positions held prior to the exchange. We will give the shareholder that requested the exchange notice in writing in this instance.

DIVIDENDS AND DISTRIBUTIONS

Dividends are based on estimates of income, expenses, and shareholder activity for the Fund. Actual income, expenses, and shareholder activity may differ from estimates; consequently, differences, if any, will be included in the calculation of subsequent dividends. The Funds pay their net investment income to shareholders of record on the business day prior to the payment date. These Funds declare dividends of their daily net investment income each day their shares are priced. On the last business day of each month the Funds will pay out their accumulated declared dividends.

Net realized capital gains, if any, are distributed annually. Generally the distribution is made on the fourth business day of December. Payments are made to shareholders of record on the business day prior to the payable date. Capital gains may be taxable at different rates, depending on the length of time that the Fund holds its assets.

Dividend and capital gains distributions will be reinvested, without a sales charge, in shares of the Fund from which the distribution is paid. However, you may authorize the distribution to be:

·      invested in shares of another fund of Principal Funds without a sales charge (distributions of a Fund may be directed only to one receiving Fund); or
·      paid in cash, if the amount is $10 or more.

Generally, for federal income tax purposes, Fund distributions are taxable as ordinary income, except that any distributions of long-term capital gains will be taxed as such regardless of how long Fund shares have been held. Special tax rules apply to Fund distributions to Individual Retirement Accounts and other retirement plans. A tax advisor should be consulted to determine the suitability of the Fund as an investment by such a plan and the tax treatment of distributions by the Fund. A tax advisor can also provide information on the potential impact of possible foreign, state, and local taxes. A Fund's investments in foreign securities may be subject to foreign withholding taxes. In that case, the Fund's yield on those securities would be decreased.

To the extent that distributions the Funds pay are derived from a source other than net income (such as a return of capital), a notice will be included in your quarterly statement pursuant to Section 19(a) of the Investment Company Act of 1940, as amended, and Rule 19a-1 disclosing the source of such distributions. Furthermore, such notices shall be posted monthly on our web site at www.principalfunds.com. You may request a copy of all such notices, free of charge, by telephoning 1-800-222-5852. The amounts and sources of distributions included in such notices are estimates only and you should not rely upon them for purposes of reporting income taxes. The Fund will send shareholders a Form 1099-DIV for the calendar year that will tell shareholders how to report these distributions for federal income tax purposes.

FUND ACCOUNT INFORMATION

Statements

You will receive quarterly statements for the Funds you own. The statements provide the number and value of shares you own, transactions during the period, dividends declared or paid and other information. The year-end statement includes information for all transactions that took place during the year. Please review your statement as soon as you receive it. Keep your statements as you may need them for tax reporting purposes.

Generally, each time you buy, sell or exchange shares in Principal Funds, you will receive a confirmation in the mail shortly thereafter. It summarizes all the key information - what you bought or sold, the amount of the transaction, and other vital data.

Certain purchases and sales are only included on your quarterly statement. These include accounts:

·      when the only activity during the quarter:
  ·      is purchase of shares from reinvested dividends and/or capital gains;
  ·      are purchases under an Automatic Investment Plan;
  ·      are sales under a Systematic Withdrawal Plan; or
  ·      are purchases or sales under an Automatic Exchange Election.
·      used to fund certain individual retirement or individual pension plans; or
·      established under a payroll deduction plan.

If you need information about your account(s) at other times, you may:

·      access your account on the internet at www.principal.com,
·      call our Automated Telephone System, 7 days a week, 24 hours a day at 1-800-222-5852, option 1, or
·      call us at 1-800-222-5852. (Our office generally is open Monday through Friday between 7 a.m. and 7 p.m. Central Time).

Orders Placed by Intermediaries

Principal Funds may have an agreement with your intermediary, such as a broker-dealer, third party administrator or trust company, that permits the intermediary to accept orders on behalf of the Fund until 3 p.m. Central Time. The agreement may include authorization for your intermediary to designate other intermediaries ("sub-designees") to accept orders on behalf of the Fund on the same terms that apply to the intermediary. In such cases, if your intermediary or a sub-designee receives your order in correct form by 3 p.m. Central Time, transmits it to the Fund and pays for it in accordance with the agreement, the Fund will price the order at the next net asset value per share it computes after your intermediary or sub-designee received your order.

NOTE: The time at which the Fund prices orders and the time until which the Fund or your intermediary or sub-designee will accept orders may change in the case of an emergency or if the New York Stock Exchange closes at a time other than 3 p.m. Central Time.

Signature Guarantees

Certain transactions require a Medallion Signature Guarantee. If required, the signature(s) must be guaranteed by a commercial bank, trust company, credit union, savings and loan, national securities exchange member or brokerage firm. A signature guarantee by a notary public or savings bank is not acceptable. Signature guarantees are required:

·      if you sell more than $100,000 from any one Fund;
·      if a sales proceeds check is payable to other than the account shareholder(s), Principal Life or Principal Bank;
·      to change ownership of an account;
·      to add wire privileges to an existing account;
·      to change bank account information designated under an existing systematic withdrawal plan;
·      to exchange or transfer among accounts with different ownership; and
·      to have a sales proceeds check mailed to an address other than the address on the account or to the address on the account if it has been changed within the preceding 30 days.

Special Plans

The Funds reserve the right to amend or terminate the special plans described in this prospectus. Such plans include automatic investment, systematic withdrawal, waiver of Fund minimums for certain accounts and waiver or reduction of the contingent deferred sales charge for certain purchasers. You will be notified of any such action to the extent required by law.

Minimum Account Balance

Generally, the Funds do not have a minimum required balance. Because of the disproportional high cost of maintaining small accounts, the Funds reserve the right to set a minimum and sell all shares in an account with a value of less than $300. The sales proceeds would then be mailed to you. These involuntary sales will not be triggered just by market conditions. If the Funds exercise this right, you will be notified that the redemption is going to be made. You will have 30 days to make an additional investment and bring your account up to the required minimum. The Funds reserve the right to increase the required minimum.

Telephone and Internet Instructions

The Funds reserve the right to refuse telephone and/or internet instructions. You are liable for a loss resulting from a fraudulent telephone or internet instruction that we reasonably believe is genuine. We use reasonable procedures to assure instructions are genuine. If the procedures are not followed, we may be liable for loss due to unauthorized or fraudulent transactions. The procedures include: recording all telephone instructions, requiring the use of a Personal Identification Number, requesting personal identification information (name, address, phone number, social security number, birth date, security phrase, etc.) and sending written confirmation to the shareholder's address of record.

Instructions received from one owner is binding on all owners. In the case of an account owned by a corporation or trust, instructions received from an authorized person are binding on the corporation/trust unless we have a written notification requiring that written instructions be executed by more than one authorized person.

Householding

To avoid sending duplicate copies of materials to households, the Fund will mail only one copy of each prospectus, annual and semi-annual report to shareholders having the same last name and address on the Fund's records. The consolidation of these mailings, called householding, benefits the Fund through reduced mailing expense. If you want to receive multiple copies of these materials, you may call the Fund at 1-800-222-5852. You may notify the Fund in writing. Individual copies of prospectuses and reports will be sent to you within thirty (30) days after the Fund receives your request to stop householding.

Multiple Translations

This prospectus may be translated into other languages. In the event of any inconsistencies or ambiguity as to the meaning of any word or phrase in a translation, the English text will prevail.

Procedures for Opening an Account

To help the government fight the funding of terrorism and money laundering activities, Federal law requires financial institutions to obtain, verify, and record information that identifies each person who opens an account. When you open an account, we will ask for your name, address, date of birth, and other information that will allow us to verify your identity. We may also ask to see your driver's license or other identifying documents.

If concerns arise with verification of your identification, no transactions, other than redemptions, will be permitted while we attempt to reconcile the concerns. If we are unable to verify your identify on a timely basis, we may close your account or take such other action as we deem appropriate.

Financial Statements

Shareholders will receive annual financial statements for the Funds, audited by the Funds' independent registered public accounting firm, Ernst & Young LLP. Shareholders will also receive a semiannual financial statement that is unaudited.

APPENDIX A

SUMMARY OF PRINCIPAL RISKS

The value of your investment in a Fund changes with the value of the investments held by that Fund. Many factors affect that value, and it is possible that you may lose money by investing in the Funds. Factors that may adversely affect a particular Fund as a whole are called "principal risks." The principal risks of investing in the Funds are stated above as to each Fund in the Fund's description. Each of these risks is summarized below. Additional information about the Funds, their investments, and the related risks is located under "Certain Investment Strategies and Related Risks" and in the Statement of Additional Information.

Active Trading Risk

A fund that actively trades portfolio securities in an attempt to achieve its investment objective may have high portfolio turnover rates that may increase the fund's brokerage costs, accelerate the realization of taxable gains, and adversely impact fund performance.

Derivatives Risk

Derivatives are investments whose values depend on or are derived from other securities or indexes. A fund's use of certain derivative instruments (such as options, futures, and swaps) could produce disproportionate gains or losses. Derivatives are generally considered riskier than direct investments and, in a down market, could become harder to value or sell at a fair price.

Emerging Market Risk

Investments in emerging market countries involve special risks. Certain emerging market countries have historically experienced, and may continue to experience, certain economic problems. These may include: high rates of inflation, high interest rates, exchange rate fluctuations, large amounts of debt, balance of payments and trade difficulties, and extreme poverty and unemployment.

Equity Securities Risk

Equity securities include common, preferred, and convertible preferred stocks and securities the values of which are tied to the price of stocks, such as rights, warrants, and convertible debt securities. Common and preferred stocks represent equity ownership in a company. Stock markets are volatile, and the price of equity securities (and their equivalents) will fluctuate. The value of equity securities purchased by a fund could decline if the financial condition of the companies in which the fund invests decline or if overall market and economic conditions deteriorate.

Exchange Rate Risk

Because foreign securities are generally denominated in foreign currencies, the value of the net assets of a fund as measured in U.S. dollars will be affected by changes in exchange rates. To protect against future uncertainties in foreign currency exchange rates, the funds are authorized to enter into certain foreign currency exchange transactions. In addition, the funds' foreign investments may be less liquid and their price more volatile than comparable investments in U.S. securities. Settlement periods may be longer for foreign securities and portfolio liquidity may be affected.

Fixed-Income Securities Risk

Fixed-income securities are generally subject to two principal types of risks: interest rate risk and credit quality risk.

Interest Rate Risk. Fixed-income securities are affected by changes in interest rates. When interest rates decline, the market value of the fixed-income securities generally can be expected to rise. Conversely, when interest rates rise, the market value of fixed-income securities generally can be expected to decline.

Credit Quality Risk. Fixed-income securities are subject to the risk that the issuer of the security will not repay all or a portion of the principal borrowed and will not make all interest payments. If the credit quality of a fixed income security deteriorates after a fund has purchased the security, the market value of the security may decrease and lead to a decrease in the value of the fund's investments. Lower quality and longer maturity bonds will be subject to greater

Principal Funds, Inc.  APPENDIX A  37 
www.principal.com     


credit risk and price fluctuations than higher quality and shorter maturity bonds. Bonds held by a fund may be affected by unfavorable political, economic, or government developments that could affect the repayment of principal or the payment of interest.

Foreign Securities Risk

Foreign securities carry risks that are not generally found in securities of U.S. companies. These risks include the loss of value as a result of political instability and financial and economic events in foreign countries. In addition, nationalization, expropriation or confiscatory taxation, and foreign exchange restrictions could adversely affect a fund's investments in a foreign country. Foreign securities may be subject to less stringent reporting, accounting, and disclosure standards than are required of U.S. companies, and foreign countries may also have problems associated with and causing delays in the settlement of sales.

High Yield Securities Risk

Fixed-income securities that are not investment grade are commonly referred to as high yield securities or "junk bonds." While these securities generally provide greater income potential than investments in higher rated fixed-income securities, there is a greater risk that principal and interest payments will not be made. Issuers of these securities may even go into default or become bankrupt. High yield securities generally involve greater price volatility and may be less liquid than higher rated fixed-income securities. High yield securities are considered speculative by the major credit rating agencies.

Portfolio Duration Risk

Portfolio duration is a measure of the expected life of a fixed-income security that is used to determine the sensitivity of a security's price to changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Prepayment Risk

Mortgage-backed and asset-backed securities are subject to prepayment risk. When interest rates decline, significant unscheduled payments may result. These prepayments must then be reinvested at lower rates. Prepayments may also shorten the effective maturities of these securities, especially during periods of declining interest rates. On the other hand, during periods of rising interest rates, a reduction in prepayments may increase the effective maturities of these securities, subjecting them to the risk of decline in market value in response to rising interest rates. This may increase the volatility of a fund.

Real Estate Securities Risk

Real estate investment trusts ("REITs") or other real estate-related securities are subject to the risks associated with direct ownership of real estate, including declines in the value of real estate, risks related to general and local economic conditions, increases in property taxes and operating expenses, changes in zoning laws, changes in interest rates, and liabilities resulting from environmental problems. Equity and mortgage REITs are dependent on management skills and generally are not diversified. Equity REITs are affected by the changes in the value of the properties owned by the trust. Mortgage REITs are affected by the quality of the credit extended. Both equity and mortgage REITs:

·      may not be diversified with regard to the types of tenants (thus subject to business developments of the tenant(s));
·      may not be diversified with regard to the geographic locations of the properties (thus subject to regional economic developments);
·      are subject to cash flow dependency and defaults by borrowers; and
·      could fail to qualify for tax-free pass-through of income under the Internal Revenue Code.

Securities Lending Risk

The principal risk of securities lending is that the financial institution that borrows securities from the Fund could go bankrupt or otherwise default on its commitment under the securities lending agreement and the Fund might not be able to recover the loaned securities or their value.

Underlying Fund Risk

The Strategic Asset Management ("SAM") Portfolios operate as funds of funds and invest principally in Underlying Funds. From time to time, an underlying fund may experience relatively large investments or redemptions by a fund of

38  APPENDIX A  Principal Funds, Inc. 
    1-800-222-5852 


funds due to the reallocation or rebalancing of its assets. These transactions may have adverse effects on underlying fund performance to the extent an underlying fund is required to sell portfolio securities to meet such redemptions, or to invest cash from such investments, at times it would not otherwise do so. This may be particularly important when a fund of funds owns a significant portion of an underlying fund. These transactions may also accelerate the realization of taxable income if sales of portfolio securities result in gains, and could increase transaction costs. In addition, when a fund of funds reallocates or redeems significant assets away from an underlying fund, the loss of assets to the underlying fund could result in increased expense ratios for that fund.

Principal is the advisor to the SAM Portfolios and each of the Underlying Funds. Edge Asset Management, Inc. ("Edge") is the Sub-Advisor to the SAM Portfolios. Edge also serves as Sub-Advisor to some of the Underlying Funds. Principal and Edge are committed to minimizing the potential impact of underlying fund risk on underlying funds to the extent consistent with pursuing the investment objectives of the fund of funds which it manages. Each may face conflicts of interest in fulfilling its responsibilities to all such funds.

The following table shows the percentage of the outstanding shares of the Mortgage Securities Fund owned by SAM Portfolios as of October 31, 2007.

    Conservative  Conservative  Flexible  Strategic   
  Balanced  Balanced  Growth  Income  Growth   
Underlying Fund  Portfolio  Portfolio  Portfolio  Portfolio  Portfolio  Total 
 
Mortgage Securities Fund  47.92  9.96  16.36  14.60    88.84 

U.S. Government Securities Risk

U.S. government securities do not involve the degree of credit risk associated with investments in lower quality fixed-income securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from many other fixed-income securities. Like other fixed-income securities, the values of U.S. government securities change as interest rates fluctuate. Fluctuations in the value of a fund's securities do not affect interest income on securities already held by the fund but are reflected in the fund's price per share. Since the magnitude of these fluctuations generally is greater at times when a fund's average maturity is longer, under certain market conditions a fund may invest in short-term investments yielding lower current income rather than investing in higher yielding longer term securities.

U.S. Government Sponsored Securities Risk

A fund may invest in debt and mortgage-backed securities issued by government-sponsored enterprises such as the Federal Home Loan Mortgage Corporation, the Federal National Mortgage Association, and the Federal Home Loan Banks. Although the issuing agency, instrumentality, or corporation may be chartered or sponsored by the U.S. government, its securities are not issued or guaranteed by the U.S. Treasury.

Value Stock Risk

A fund's investments in value stocks carry the risk that the market will not recognize a security's intrinsic value for a long time or that a stock judged to be undervalued may actually be appropriately priced. A value stock may not increase in price if other investors fail to recognize the company's value and bid up the price or invest in markets favoring faster growing companies. A fund's strategy of investing in value stocks also carries the risk that in certain markets value stocks will underperform growth stocks.

APPENDIX B

Description of Bond Ratings:

Moody’s Investors Service, Inc. Rating Definitions:

Long-Term Obligation Ratings

Moody’s long-term obligation ratings are opinions of the relative credit risk of fixed-income obligations with an original maturity of one year or more. They address the possibility that a financial obligation will not be honored as promised. Such ratings reflect both the likelihood of default and any financial loss suffered in the event of default.

Aaa:  Obligations rated Aaa are judged to be of the highest quality, with minimal credit risk. 
Aa:  Obligations rated Aa are judged to be of high quality and are subject to very low credit risk. 
A:  Obligations rated A are considered upper-medium grade and are subject to low credit risk. 
Baa:  Obligations rated Baa are subject to moderate credit risk. They are considered medium-grade and as such 
  may possess certain speculative characteristics. 
Ba:  Obligations rated Ba are judged to have speculative elements and are subject to substantial credit risk. 
B:  Obligations rated B are considered speculative and are subject to high credit risk. 
Caa:  Obligations rated Caa are judged to be of poor standing and are subject to very high credit risk. 
Ca:  Obligations rated Ca are highly speculative and are likely in, or very near, default, with some prospect of 
  recovery of principal and interest. 
C:  Obligations rated C are the lowest rated class of bonds and are typically in default, with little prospect for 
  recovery of principal or interest. 

NOTE: Moody’s appends numerical modifiers, 1, 2, and 3 to each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category, the modifier 2 indicates a mid-range ranking, and the modifier 3 indicates a ranking in the lower end of that generate rating category.

SHORT-TERM NOTES: The four ratings of Moody’s for short-term notes are MIG 1, MIG 2, MIG 3, and MIG 4. MIG 1 denotes “best quality, enjoying strong protection from established cash flows.” MIG 2 denotes “high quality” with “ample margins of protection.” MIG 3 notes are of “favorable quality...but lacking the undeniable strength of the

40  APPENDIX B  Principal Funds, Inc. 
    1-800-222-5852 


preceding grades.” MIG 4 notes are of “adequate quality, carrying specific risk for having protection . . . and not distinctly 
or predominantly speculative.”
 
Description of Moody’s Commercial Paper Ratings:   

Moody’s Commercial Paper ratings are opinions of the ability to repay punctually promissory obligations not having an original maturity in excess of nine months. Moody’s employs the following three designations, all judged to be investment grade, to indicate the relative repayment capacity of rated issuers:

Issuers rated Prime-1 (or related supporting institutions) have a superior capacity for repayment of short-term promissory obligations.

Issuers rated Prime-2 (or related supporting institutions) have a strong capacity for repayment of short-term promissory obligations.

Issuers rated Prime-3 (or related supporting institutions) have an acceptable capacity for repayment of short-term promissory obligations.

Issuers rated Not Prime do not fall within any of the Prime rating categories.

Description of Standard & Poor’s Corporation’s Debt Ratings:

A Standard & Poor’s debt rating is a current assessment of the creditworthiness of an obligor with respect to a specific obligation. This assessment may take into consideration obligors such as guarantors, insurers, or lessees.

The debt rating is not a recommendation to purchase, sell or hold a security, inasmuch as it does not comment as to market price or suitability for a particular investor.

The ratings are based on current information furnished by the issuer or obtained by Standard & Poor’s from other sources Standard & Poor’s considers reliable. Standard & Poor’s does not perform an audit in connection with any rating and may, on occasion, rely on unaudited financial information. The ratings may be changed, suspended, or withdrawn as a result of changes in, or unavailability of, such information, or for other circumstances.

The ratings are based, in varying degrees, on the following considerations:

I.  Likelihood of default – capacity and willingness of the obligor as to the timely payment of interest and 
  repayment of principal in accordance with the terms of the obligation; 
 
 
 
II.  Nature of and provisions of the obligation; 
 
 
 
III.  Protection afforded by, and relative position of, the obligation in the event of bankruptcy, reorganization, or 
  other arrangement under the laws of bankruptcy and other laws affecting creditor’s rights. 
 
 
 
AAA:  Debt rated “AAA” has the highest rating assigned by Standard & Poor’s. Capacity to pay interest and repay 
  principal is extremely strong. 

Principal Funds, Inc.  APPENDIX B  41 
www.principal.com     


AA:  Debt rated “AA” has a very strong capacity to pay interest and repay principal and differs from the highest- 
  rated issues only in small degree. 
 
 
 
A:  Debt rated “A” has a strong capacity to pay interest and repay principal although they are somewhat more 
  susceptible to the adverse effects of changes in circumstances and economic conditions than debt in 
  higher-rated categories. 
 
 
 
BBB:  Debt rated “BBB” is regarded as having an adequate capacity to pay interest and repay principal. Whereas 
  it normally exhibits adequate protection parameters, adverse economic conditions or changing circum- 
  stances are more likely to lead to a weakened capacity to pay interest and repay principal for debt in this 
  category than for debt in higher-rated categories. 

BB, B, CCC, CC:   Debt rated “BB,” “B,” “CCC,” and “CC” is regarded, on balance, as predominantly speculative with 
  respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. 
  “BB” indicates the lowest degree of speculation and “CC” the highest degree of speculation. While 
  such debt will likely have some quality and protective characteristics, these are outweighed by large 
  uncertainties or major risk exposures to adverse conditions. 

C:  The rating “C” is reserved for income bonds on which no interest is being paid. 
D:  Debt rated “D” is in default, and payment of interest and/or repayment of principal is in arrears. 

Plus (+) or Minus (-): The ratings from “AA” to “B” may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

Provisional Ratings: The letter “p” indicates that the rating is provisional. A provisional rating assumes the successful completion of the project being financed by the bonds being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, however, while addressing credit quality subsequent to completion of the project, makes no comment on the likelihood of, or the risk of default upon failure of, such completion. The investor should exercise his own judgment with respect to such likelihood and risk.

NR:  Indicates that no rating has been requested, that there is insufficient information on which to base a rating or 
  that Standard & Poor’s does not rate a particular type of obligation as a matter of policy. 

Standard & Poor’s, Commercial Paper Ratings

A Standard & Poor’s Commercial Paper Rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days. Ratings are graded into four categories, ranging from “A” for the highest quality obligations to “D” for the lowest. Ratings are applicable to both taxable and tax-exempt commercial paper. The four categories are as follows:

A:  Issues assigned the highest rating are regarded as having the greatest capacity for timely payment. Issues 
  in this category are delineated with the numbers 1, 2, and 3 to indicate the relative degree of safety. 

42  APPENDIX B  Principal Funds, Inc. 
    1-800-222-5852 


A-1:  This designation indicates that the degree of safety regarding timely payment is either overwhelming or 
  very strong. Issues that possess overwhelming safety characteristics will be given a “+” designation. 
 
 
 
A-2:  Capacity for timely payment on issues with this designation is strong. However, the relative degree of 
  safety is not as high as for issues designated “A-1.” 
 
 
 
A-3:  Issues carrying this designation have a satisfactory capacity for timely payment. They are, however, some- 
  what more vulnerable to the adverse effects of changes in circumstances than obligations carrying the 
  highest designations. 
 
 
 
B:  Issues rated “B” are regarded as having only an adequate capacity for timely payment. However, such 
  capacity may be damaged by changing conditions or short-term adversities. 
 
 
 
C:  This rating is assigned to short-term debt obligations with a doubtful capacity for payment. 
 
 
 
D:  This rating indicates that the issue is either in default or is expected to be in default upon maturity. 

The Commercial Paper Rating is not a recommendation to purchase or sell a security. The ratings are based on current information furnished to Standard & Poor’s by the issuer and obtained by Standard & Poor’s from other sources it considers reliable. The ratings may be changed, suspended, or withdrawn as a result of changes in or unavailability of, such information.

Standard & Poor’s rates notes with a maturity of less than three years as follows:

SP-1:  A very strong, or strong, capacity to pay principal and interest. Issues that possess overwhelming safety 
  characteristics will be given a “+” designation. 
SP-2:  A satisfactory capacity to pay principal and interest. 
SP-3:  A speculative capacity to pay principal and interest.

Princor Financial Services Corporation* ("Princor") and Principal Funds Distributor, Inc. *(“PFD”) are co-distributors (together, “the Distributors”) for R-1, R-2, R-3, R-4, and R-5 Class shares. Principal Management Corporation* ("Principal"), the manager of the Fund, seeks to provide a broad range of investment approaches through Principal Funds, one of which, Mortgage Securities Fund, (“the Fund”) is offered through this prospectus. The Sub-Advisor for the Mortgage Securities Fund is Edge Asset Management, Inc.*

*      Principal Management Corporation; Principal Funds Distributor, Princor Financial Services Corporation and Edge Asset Management, Inc. are affiliates of Principal Life Insurance Company and with it are subsidiaries of Principal Financial Group, Inc. and members of the Principal Financial Group® .

The Fund offers five classes of shares through this prospectus, each of which may be purchased through retirement plans though not all plans offer the Fund. Such plans may impose fees in addition to those charged by the Fund. The services or share classes available to you may vary depending upon how you wish to purchase shares of the Fund. Each share class represents investments in the same portfolio of securities, but each class has its own expense structure, allowing you to choose the class that best meets your situation (not all classes are available to all plans).

EACH INVESTOR'S FINANCIAL CONSIDERATIONS ARE DIFFERENT. YOU SHOULD SPEAK WITH YOUR FINANCIAL ADVISOR TO HELP YOU DECIDE WHICH SHARE CLASS IS BEST FOR YOU.

Principal Funds, Inc.  RISK/RETURN SUMMARY  3

In the description for the Fund, there is important information about the Fund's:

Main Strategies and Risks

This section describes the Fund's investment objective and summarizes how the Fund intends to achieve its investment objective. The Board of Directors may change the Fund's objective or investment strategies without a shareholder vote if it determines such a change is in the best interests of the Fund. If there is a material change to the Fund's investment objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that the Fund will meet its objective.

The section also describes the Fund's primary investment strategies (including the type or types of securities in which the Fund invests), any policy of the Fund to concentrate in securities of issuers in a particular industry or group of industries and the main risks associated with an investment in the Fund. A fuller discussion of risks appears later in the Prospectus under the caption "Certain Investment Strategies and Related Risks."

The Fund may invest up to 100% of its assets in cash and cash equivalents for temporary defensive purposes in response to adverse market, economic, or political conditions as more fully described under the caption "Certain Investment Strategies and Related Risks-Temporary Defensive Measures."

The Fund is designed to be a portion of an investor's portfolio. The Fund is not intended to be a complete investment program. Investors should consider the risks of the Fund before making an investment and be prepared to bear investment losses during periods of adverse market conditions. The value of your investment in the Fund changes with the value of the investments held by the Fund. Many factors affect that value, and it is possible that you may lose money by investing in the Fund. Factors that may adversely affect a particular Fund as a whole are called "principal risks." The principal risks of investing in the Fund are stated in the Fund's description. The Fund is also subject to underlying fund risk to the extent that a SAM Portfolio invests in the Fund. These risks are more fully explained in Appendix A to this prospectus.

Fees and Expenses

The annual operating expenses for the Fund are deducted from the Fund's assets (stated as a percentage of Fund assets). The Fund's operating expenses are shown following the Fund’s description. A discussion of the fees is found in the section of the Prospectus titled "The Costs of Investing."

The example following the expense table for the Fund is intended to help investors compare the cost of investing in this Fund with the cost of investing in other mutual funds.

NOTES:

·      No salesperson, dealer or other person is authorized to give information or make representations about a Fund other than those contained in this Prospectus. Information or representations not contained in this prospectus may not be relied upon as having been made by Principal Funds, the Fund, Principal, the Sub-Advisor, Princor, or PFD.

MORTGAGE SECURITIES FUND

Sub-Advisor(s): 

 

Edge Asset Management, Inc. (“Edge”) 

 

Objective: 

 

The Fund seeks to provide a high level of current income consistent with safety and liquidity. 

 

Investor Profile:  The Fund may be appropriate for investors seeking diversification by investing in a fixed- 
  income mutual fund. 

Main Strategies and Risks

The Fund invests primarily in mortgage-backed securities, including collateralized mortgage obligations. The Fund may also invest in dollar rolls, which may involve leverage.

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in mortgage-backed securities, including collateralized mortgage obligations, and in other obligations that are secured by mortgages or mortgage-backed securities, including repurchase agreements. The Fund may also invest in U.S. government securities. Certain issuers of U.S. government securities are sponsored or chartered by Congress but their securities are neither issued or guaranteed by the U.S. Treasury. The Fund may lend its portfolio securities to brokers, dealers, and other financial institutions. The Fund may use futures, options, swaps and derivative instruments to “hedge” or protect its portfolio from adverse movements in securities prices and interest rates.

The Fund invests in mortgage securities which represent good longer term value, taking into account potential returns, prepayment and credit risk as well as deal-structure where appropriate. The Fund also invests in Treasury and Agency securities primarily for duration and liquidity management purposes.

Among the principal risks (defined in Appendix A) of investing in the Fund are:

• Fixed-Income Securities Risk  • Derivatives Risk  • Prepayment Risk 
• Underlying Fund Risk  • Portfolio Duration Risk  • U.S. Government Securities Risk 
• U.S. Government Sponsored  • Securities Lending Risk   
       Securities Risk     

Edge has provided investment advice to the Fund since the Fund’s inception.

(1)      R-1, R-2, R-3, R-4 and R-5 shares were first sold on December 15, 2008. For periods prior to the date on which these classes began operations, their returns are based on the performance of the Fund’s Class A shares adjusted to reflect the fees and expenses of these classes. The adjustments result in performance (for the periods prior to the date these classes began operations) that is no higher than the historical performance of the Class A shares. The Fund commenced operations after succeeding to the operations of another fund on January 12, 2007.
 
  On March 1, 2004, the investment policies of the predecessor fund were modified. As a result, the Fund’s performance for periods prior to that date may not be representative of the performance it would have achieved had its current investment policies been in place.
 
(2)      Index performance information reflects no deduction for fees, expenses, or taxes.

Example

The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, regardless of whether you redeem or continue to hold the shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

THE COSTS OF INVESTING

Fees and Expenses of the Funds

The shares of the Fund are sold without a front-end sales charge and do not have a contingent deferred sales charge. There is no sales charge on shares of the Fund purchased with reinvested dividends or other distributions.

Ongoing Fees

Ongoing fees reduce the value of each share. Because they are ongoing, they increase the cost of investing in the Fund.

The Fund pays ongoing fees to Principal and others who provide services to the Fund. These fees include:

·      Management Fee - Through the Management Agreement with Principal Funds, Principal has agreed to provide investment advisory services and corporate administrative services to the Fund.
·      Distribution Fee - The Funds has adopted a distribution plan under Rule 12b-1 of the Investment Company Act of 1940. Under the plan, the R-1, R-2, R-3, and R-4 classes of the Fund pay a distribution fee based on the average daily net asset value (NAV) of the Fund. These fees pay distribution and other expenses for the sale of Fund shares and for services provided to shareholders. Over time, these fees may exceed other types of sales charges.
·      Service Fee - Principal has entered into a Service Agreement with Principal Funds under which Principal performs personal services for shareholders.
·      Administrative Services Fee - Principal has entered into an Administrative Services Agreement with Principal Funds under which Principal provides shareholder and administrative services for retirement plans and other beneficial owners of Fund shares.
·      Other Expenses - A portion of expenses that are allocated to all classes of Principal Funds.

DISTRIBUTION PLANS AND INTERMEDIARY COMPENSATION

The Fund has adopted a 12b-1 Plan for the R-1, R-2, R-3, and R-4 Class shares of the Fund. Under the 12b-1 Plans, the Fund will make payments from its assets attributable to the particular share class to the Fund's Distributors for distribution-related expenses and for providing services to shareholders of that share class. Payments under the 12b-1 plans will not automatically terminate for funds that are closed to new investors or to additional purchases by existing shareholders. The fund Board will determine whether to terminate, modify, or leave unchanged the 12b-1 plan at the time the Board directs the implementation of the closure of the fund. Because Rule 12b-1 fees are ongoing fees, over time they will increase the cost of an investment in the Fund and may cost more than paying other types of sales charges.

The Distributors for all of the share classes of Principal Funds described in this prospectus are Princor Financial Services Corporation (“Princor”) and Principal Funds Distributor, Inc. (“PFD”), wholly owned subsidiaries of PFG. The term "Distributors" as used in this section refers to Princor and PFD.

The maximum annual Rule 12b-1 distribution and/or service fee (as a percentage of average daily net assets) for each of the above classes of the Funds are set forth below:

  Maximum Annualized 
Share Class  Rule 12b-1 Fee 
R-1  0.35% 
R-2  0.30% 
R-3  0.25% 
R-4  0.10% 

Payments to Investment Representatives and Their Firms. Financial intermediaries market and sell shares of the Fund. These financial intermediaries receive compensation from the Distributors and their affiliates for selling shares of the Fund and/or providing services to the Fund’s shareholders. Financial intermediaries may include, among others, broker-dealers, registered investment advisors, banks, trust companies, pension plan consultants, retirement plan administrators, and insurance companies. Investment Representatives who deal with investors are typically associated with a financial intermediary. The Distributors and their affiliates may fund this compensation from various

Principal Funds, Inc.  THE COSTS OF INVESTING  9 
www.principal.com     


sources, including any Rule 12b-1 Plan fee that the shareholder or the Fund pays to the Distributors. Individual Investment Representatives may receive some or all of the amounts paid to the financial intermediary with which he or she is associated.

Other Payments to Intermediaries. In addition to the commissions paid at the time of sale, ongoing payments, and the reimbursement of costs associated with education, training and marketing efforts, conferences, seminars, due diligence trip expenses, ticket charges, and other general marketing expenses, some or all of which will, in most cases, be paid to financial intermediaries (and, in turn, to your Investment Representative), the Distributors and their affiliates, at their expense, currently provide additional payments to financial intermediaries that sell shares of the Fund for distribution services. Although payments made to each qualifying financial intermediary in any given year may vary, such payments will generally not exceed (a) 0.25% of the current year's sales of Fund shares by that financial intermediary and/or (b) 0.25% of average daily net assets of Fund shares serviced by that financial intermediary over the year.

A number of factors are considered in determining the amount of these additional payments, including each financial intermediary's Fund sales, assets, and redemption rates as well as the willingness and ability of the financial intermediary to give the Distributors access to their Investment Representatives for educational and marketing purposes. In some cases, financial intermediaries will include the Fund on a "preferred list." The Distributors’ goals include making the Investment Representatives who interact with current and prospective investors and shareholders more knowledgeable about the Fund so that they can provide suitable information and advice about the Fund and related investor services.

Additionally, the Distributors will, in most cases, provide payments to reimburse directly or indirectly the costs incurred by these financial intermediaries and their associated Investment Representatives in connection with educational seminars and training and marketing efforts related to the Funds for the firms' employees and/or their clients and potential clients. The costs and expenses associated with these efforts may include travel, lodging, entertainment, and meals. The Distributors will also, in some cases, provide payment or reimbursement for expenses associated with qualifying dealers' conferences, transactions ("ticket") charges, and general marketing expenses.

In connection with the purchase by Principal Management Corporation ("Principal") of WM Advisors, Inc. ("WM Advisors"), the investment advisor to the WM Funds, and WM Advisors' two subsidiaries, WM Funds Distributor, Inc. and WM Shareholder Services, Inc. (the "Transaction"), New American Capital, Inc. and its parent company Washington Mutual, Inc. ("WaMu") have agreed to make certain contingent payments to Principal with respect to each of the first four years following the closing of the Transaction. Such payments must be made if aggregate management fee revenues to Principal and its affiliates from assets under management in funds and other financial products advised by Principal and its affiliates (including the fund covered by this prospectus) (collectively, the "Principal Products") sold through WaMu and its affiliates (including WaMu Investments, a broker-dealer subsidiary of WaMu) fall below certain specified targets during any such year. This could result in up to $30 million being paid by WaMu or New American Capital, Inc. to Principal with respect to each of those four years following the closing of the Transaction. As a result, WaMu Investments (and/or it affiliates) will have an additional incentive to sell Principal Products following the closing of the Transaction.

If one mutual fund sponsor makes greater distribution assistance payments than another, your Investment Representative and his or her financial intermediary may have an incentive to recommend one fund complex over another. Similarly, if your Investment Representative or his or her financial intermediary receives larger distribution assistance payments for one share class versus another, then they may have an incentive to recommend that share class.

Please speak with your Investment Representative to learn more about the total amounts paid to your Investment Representative and his or her financial intermediary by the Fund, the Distributors and their affiliates, and by sponsors of other mutual funds he or she may recommend to you. You should also carefully review disclosures made by your Investment Representative at the time of purchase.

Although the Fund may use brokers who sell shares of the Fund to effect portfolio transactions, the sale of shares is not considered as a factor by the Fund's Sub-Advisor when selecting brokers to effect portfolio transactions.

Your financial intermediary may charge fees and commissions, including processing fees, in addition to those described in this prospectus. The amount and applicability of any such fee is determined and disclosed separately by the financial intermediary. You should ask your Investment Representative for information about any fees and/or commissions that are charged.

Retirement Plan Services. The Fund pays a Service Fee and Administrative Services Fee to Principal for providing services to retirement plan shareholders. Principal typically pays some or all of these fees to Principal Life Insurance Company, which has entered into an agreement to provide these services to the retirement plan shareholders. Principal may also enter into agreements with other intermediaries to provide these services, and pay some or all of the Fees to such intermediaries.

Plan recordkeepers, who may have affiliated financial intermediaries that sell shares of the fund, may be paid additional amounts. In addition, financial intermediaries may be affiliates of entities that receive compensation from the Distributors for maintaining retirement plan "platforms" that facilitate trading by affiliated and non-affiliated financial intermediaries and recordkeeping for retirement plans.

Principal Funds, Inc.  DISTRIBUTION PLANS AND INTERMEDIARY COMPENSATION  11 
www.principal.com     


The amounts paid to plan recordkeepers for recordkeeping services, and their related service requirements may vary across fund groups and share classes. This may create an incentive for financial intermediaries and their Investment Representatives to recommend one fund complex over another or one class of shares over another.

CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS

The Statement of Additional Information (SAI) contains additional information about investment strategies and their related risks.

Credit and Counterparty Risk

The fund is subject to the risk that the issuer or guarantor of a fixed-income security or other obligation, the counterparty to a derivatives contract or repurchase agreement, or the borrower of a portfolio's securities will be unable or unwilling to make timely principal, interest, or settlement payments, or otherwise to honor its obligations.

Liquidity Risk

A fund is exposed to liquidity risk when trading volume, lack of a market maker, or legal restrictions impair the fund's ability to sell particular securities or close derivative positions at an advantageous price. Funds with principal investment strategies that involve securities of companies with smaller market capitalizations, foreign securities, derivatives, or securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk.

Management Risk

The fund is actively managed by its investment advisor or sub-advisor(s). The performance of a fund that is actively managed will reflect in part the ability of the advisor or sub-advisor(s) to make investment decisions that are suited to achieving the fund's investment objective. If the advisor's or sub-advisor(s)' strategies do not perform as expected, the fund could underperform other mutual funds with similar investment objectives or lose money.

Securities and Investment Practices

Market Volatility. Equity securities include common stocks, preferred stocks, convertible securities, depositary receipts, rights, and warrants. Common stocks, the most familiar type, represent an equity (ownership) interest in a corporation. The value of a company's stock may fall as a result of factors directly relating to that company, such as decisions made by its management or lower demand for the company's products or services. A stock's value may also fall because of factors affecting not just the company, but also companies in the same industry or in a number of different industries, such as increases in production costs. The value of a company's stock may also be affected by changes in financial markets that are relatively unrelated to the company or its industry, such as changes in interest rates or currency exchange rates. In addition, a company's stock generally pays dividends only after the company invests in its own business and makes required payments to holders of its bonds and other debt. For this reason, the value of a company's stock will usually react more strongly than its bonds and other debt to actual or perceived changes in the company's financial condition or prospects. Stocks of smaller companies may be more vulnerable to adverse developments than those of larger companies.

Fixed-income securities include bonds and other debt instruments that are used by issuers to borrow money from investors. The issuer generally pays the investor a fixed, variable, or floating rate of interest. The amount borrowed must be repaid at maturity. Some debt securities, such as zero coupon bonds, do not pay current interest, but are sold at a discount from their face values.

Interest Rate Changes. Fixed-income securities are sensitive to changes in interest rates. In general, fixed-income security prices rise when interest rates fall and fall when interest rates rise. Longer term bonds and zero coupon bonds are generally more sensitive to interest rate changes.

Repurchase Agreements and Loaned Securities

The Fund may invest a portion of its assets in repurchase agreements. Repurchase agreements typically involve the purchase of debt securities from a financial institution such as a bank, savings and loan association, or broker-dealer. A repurchase agreement provides that the Fund sells back to the seller and that the seller repurchases the underlying securities at a specified price on a specific date. Repurchase agreements may be viewed as loans by a Fund

12  CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS  Principal Funds, Inc. 
    1-800-547-7754 


collateralized by the underlying securities. This arrangement results in a fixed rate of return that is not subject to market fluctuation while the Fund holds the security. In the event of a default or bankruptcy by a selling financial institution, the affected Fund bears a risk of loss. To minimize such risks, the Fund enters into repurchase agreements only with large, well-capitalized and well-established financial institutions. In addition, the value of the securities collateralizing the repurchase agreement is, and during the entire term of the repurchase agreement remains, at least equal to the repurchase price, including accrued interest.

The Fund may lend its portfolio securities to unaffiliated broker-dealers and other unaffiliated qualified financial institutions. These transactions involve a risk of loss to the Fund if the counterparty should fail to return such securities to the Fund upon demand or if the counterparty's collateral invested by the Fund declines in value as a result of the investment losses.

Derivatives

To the extent permitted by its investment objectives and policies, the Fund may invest in securities that are commonly referred to as derivative securities. Generally, a derivative is a financial arrangement, the value of which is derived from, or based on, a traditional security, asset, or market index. Certain derivative securities are described more accurately as index/structured securities. Index/structured securities are derivative securities whose value or performance is linked to other equity securities (such as depositary receipts), currencies, interest rates, indices, or other financial indicators (reference indices).

Some derivatives, such as mortgage-related and other asset-backed securities, are in many respects like any other investment, although they may be more volatile or less liquid than more traditional debt securities.

There are many different types of derivatives and many different ways to use them. Futures and options are commonly used for traditional hedging purposes to attempt to protect a Fund from exposure to changing interest rates, securities prices, or currency exchange rates and for cash management purposes as a low-cost method of gaining exposure to a particular securities market without investing directly in those securities. The Funds may enter into put or call options, futures contracts, options on futures contracts, over-the-counter swap contracts (e.g., interest rate swaps, total return swaps, and credit default swaps), and forward currency contracts for both hedging and non-hedging purposes.

Generally, the Fund may not invest in a derivative security unless the reference index or the instrument to which it relates is an eligible investment for the Fund or the reference currency relates to an eligible investment for the Fund.

The return on a derivative security may increase or decrease, depending upon changes in the reference index or instrument to which it relates. The risks associated with derivative investments include:

·      the risk that the underlying security, interest rate, market index, or other financial asset will not move in the direction the Sub-Advisor anticipated;
·      the possibility that there may be no liquid secondary market which may make it difficult or impossible to close out a position when desired;
·      the risk that adverse price movements in an instrument can result in a loss substantially greater than a Fund's initial investment; and
·      the counterparty may fail to perform its obligations.

Foreign Investing

The Fund may invest in securities of foreign companies but not as a principal investment strategy. For the purpose of this restriction, foreign companies are:

·      companies with their principal place of business or principal office outside the U.S or
·      companies for which the principal securities trading market is outside the U.S.

Foreign companies may not be subject to the same uniform accounting, auditing, and financial reporting practices as are required of U.S. companies. In addition, there may be less publicly available information about a foreign company than about a U.S. company. Securities of many foreign companies are less liquid and more volatile than securities of comparable U.S. companies. Commissions on foreign securities exchanges may be generally higher than those on U.S. exchanges.

Principal Funds, Inc.  CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS  13

Foreign markets also have different clearance and settlement procedures than those in U.S. markets. In certain markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct these transactions. Delays in settlement could result in temporary periods when a portion of Fund assets is not invested and earning no return. If the Fund is unable to make intended security purchases due to settlement problems, the Fund may miss attractive investment opportunities. In addition, the Fund may incur a loss as a result of a decline in the value of its portfolio if it is unable to sell a security.

With respect to certain foreign countries, there is the possibility of expropriation or confiscatory taxation, political or social instability, or diplomatic developments that could affect the Fund's investments in those countries. In addition, the Fund may also suffer losses due to nationalization, expropriation or differing accounting practices and treatments. Investments in foreign securities are subject to laws of the foreign country that may limit the amount and types of foreign investments. Changes of governments or of economic or monetary policies, in the U.S. or abroad, changes in dealings between nations, or currency convertibility or exchange rates could result in investment losses for the Fund. Finally, even though certain currencies may be convertible into U.S. dollars, the conversion rates may be artificial relative to the actual market values and may be unfavorable to Fund investors.

Foreign securities are often traded with less frequency and volume, and therefore may have greater price volatility, than is the case with many U.S. securities. Brokerage commissions, custodial services, and other costs relating to investment in foreign countries are generally more expensive than in the U.S. Though the Fund intends to acquire the securities of foreign issuers where there are public trading markets, economic or political turmoil in a country in which the Fund has a significant portion of its assets or deterioration of the relationship between the U.S. and a foreign country may negatively impact the liquidity of the Fund's portfolio. The Fund may have difficulty meeting a large number of redemption requests. Furthermore, there may be difficulties in obtaining or enforcing judgments against foreign issuers.

The Fund may choose to invest in a foreign company by purchasing depositary receipts. Depositary receipts are certificates of ownership of shares in a foreign-based issuer held by a bank or other financial institution. They are alternatives to purchasing the underlying security but are subject to the foreign securities to which they relate.

Investments in companies of developing (also called “emerging”) countries are subject to higher risks than investments in companies in more developed countries. These risks include:

·      increased social, political, and economic instability;
·      a smaller market for these securities and low or nonexistent volume of trading that results in a lack of liquidity and greater price volatility;
·      lack of publicly available information, including reports of payments of dividends or interest on outstanding securities;
·      foreign government policies that may restrict opportunities, including restrictions on investment in issuers or industries deemed sensitive to national interests;
·      relatively new capital market structure or market-oriented economy;
·      the possibility that recent favorable economic developments may be slowed or reversed by unanticipated political or social events in these countries;
·      restrictions that may make it difficult or impossible for the Fund to vote proxies, exercise shareholder rights, pursue legal remedies, and obtain judgments in foreign courts; and
·      possible losses through the holding of securities in domestic and foreign custodial banks and depositories.

In addition, many developing countries have experienced substantial and, in some periods, extremely high rates of inflation for many years. Inflation and rapid fluctuations in inflation rates have had and may continue to have negative effects on the economies and securities markets of those countries.

Repatriation of investment income, capital and proceeds of sales by foreign investors may require governmental registration and/or approval in some developing countries. The Fund could be adversely affected by delays in or a refusal to grant any required governmental registration or approval for repatriation.

Further, the economies of developing countries generally are heavily dependent upon international trade and, accordingly, have been and may continue to be adversely affected by trade barriers, exchange controls, managed

14  CERTAIN INVESTMENT STRATEGIES AND RELATED RISKS  Principal Funds, Inc. 
    1-800-547-7754 


adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which they trade.

Temporary Defensive Measures

From time to time, as part of its investment strategy, the Fund may invest without limit in cash and cash equivalents for temporary defensive purposes in response to adverse market, economic, or political conditions. To the extent that the Fund is in a defensive position, it may lose the benefit of upswings and limit its ability to meet its investment objective. For this purpose, cash equivalents include: bank notes, bank certificates of deposit, bankers' acceptances, repurchase agreements, commercial paper, and commercial paper master notes which are floating rate debt instruments without a fixed maturity. In addition, the Fund may purchase U.S. government securities, preferred stocks, and debt securities, whether or not convertible into or carrying rights for common stock.

There is no limit on the extent to which the Fund may take temporary defensive measures. In taking such measures, the Fund may fail to achieve its investment objective.

Portfolio Turnover

"Portfolio Turnover" is the term used in the industry for measuring the amount of trading that occurs in a Fund's portfolio during the year. For example, a 100% turnover rate means that on average every security in the portfolio has been replaced once during the year. Funds that engage in active trading may have higher portfolio turnover rates.

Funds with high turnover rates (more than 100%) often have higher transaction costs (which are paid by the Fund) which may have an adverse impact on the Fund's performance.

MANAGEMENT OF THE FUND

The Manager

Principal Management Corporation ("Principal") serves as the manager for the Fund. Through the Management Agreement with the Fund, Principal provides investment advisory services and certain corporate administrative services for the Fund.

Principal is an indirect subsidiary of Principal Financial Group, Inc. and has managed mutual funds since 1969. Principal's address is Principal Financial Group, 680 8th Street, Des Moines, Iowa 50392.

The Sub-Advisors

Principal has signed a contract with a Sub-Advisor. Under the sub-advisory agreement, the Sub-Advisor agrees to assume the obligations of Principal to provide investment advisory services for a specific Fund. For these services, the Sub-Advisor is paid a fee by Principal. Information regarding the Sub-Advisor and the individual portfolio manager is set forth below. The Statement of Additional Information provides additional information about the portfolio manager's compensation, other accounts managed by the portfolio manager, and the portfolio manager's ownership of securities in the Fund.

Sub-Advisor: Edge Asset Management, Inc. (“Edge”) is an affiliate of Principal and a member of the Principal

Duties of Principal and Sub-Advisors

Principal or the Sub-Advisor provides the Directors of the Fund with a recommended investment program. The program must be consistent with the Fund's investment objective and policies. Within the scope of the approved investment program, the Sub-Advisor advises the Fund on its investment policy and determines which securities are bought or sold, and in what amounts.

Fees Paid to Principal

The Fund pays Principal a fee for its services, which includes any fee Principal pays to the Sub-Advisor. The fee the Fund paid (as a percentage of the average daily net assets) for the fiscal year ended October 31, 2007 was: 0.50% .

A discussion regarding the basis for the Board of Directors approving the management agreement with Principal and the sub-advisory agreement this Sub-Advisor was included in the annual report to shareholders for the fiscal year ended October 31, 2007.

Under an order received from the SEC, Principal Funds, may enter into and materially amend agreements with Sub-Advisors, other than those affiliated with Principal, without obtaining shareholder approval. For any Fund that is relying on that order, Principal may, without obtaining shareholder approval:

·      hire one or more Sub-Advisors;
·      change Sub-Advisors; and
·      reallocate management fees between itself and Sub-Advisors.

Principal has ultimate responsibility for the investment performance of each Fund that utilizes a Sub-Advisor due to its responsibility to oversee Sub-Advisors and recommend their hiring, termination, and replacement. No Fund will rely on the order until it receives approval from its shareholders or, in the case of a new Fund, the Fund's sole initial shareholder before the Fund is available to the other purchasers, and the Fund states in its prospectus that it intends to rely on the order.

The shareholders of the Fund have approved the Fund's reliance on the order; however, the Fund does not intend to rely on the order.

PRICING OF FUND SHARES

The Fund's shares are bought and sold at the current share price. The share price of each class of the Fund is calculated each day the New York Stock Exchange ("NYSE") is open (shares are not priced on the days on which the NYSE is closed for trading, generally New Year's Day, Martin Luther King, Jr. Day, Washington's Birthday/Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas). The share price is determined as of the close of business of the NYSE (normally 3:00 p.m. Central Time). When an order to buy or sell shares is received, the share price used to fill the order is the next price calculated after the order is received in good order by us at our transaction processing center in Canton, Massachusetts. In order for us to process your purchase order on the day it is received, we must receive the order (with complete information):

·      on a day that the NYSE is open and
·      prior to the close of trading on the NYSE (normally 3 p.m. Central Time).

Orders received after the close of the NYSE or on days that the NYSE is not open will be processed on the next day that the NYSE is open for normal trading.

If we receive an application or purchase request for a new mutual fund account or subsequent purchase into an existing account that is accompanied by a check and the application or purchase request does not contain complete information, we may hold the application (and check) for up to two business days while we attempt to obtain the necessary information. If we receive the necessary information within two business days, we will process the order using the next share price calculated. If we do not receive the information within two business days, the application and check will be returned to you.

16  PRICING OF FUND SHARES  Principal Funds, Inc. 
    1-800-547-7754 


For this Fund the share price is calculated by:

·      taking the current market value of the total assets of the Fund
·      subtracting liabilities of the Fund
·      dividing the remainder proportionately into the classes of the Fund
·      subtracting the liability of each class
·      dividing the remainder by the total number of shares owned in that class.

NOTES:

·      If market quotations are not readily available for a security owned by a Fund, its fair value is determined using a policy adopted by the Directors. Fair valuation pricing is subjective and creates the possibility that the fair value determined for a security may differ materially from the value that could be realized upon the sale of the security.
 
·      A Fund's securities may be traded on foreign securities markets that generally complete trading at various times during the day prior to the close of the NYSE. Generally, the values of foreign securities used in computing a Fund's NAV are the market quotations as of the close of the foreign market. Foreign securities and currencies are also converted to U.S. dollars using the exchange rate in effect at the close of the NYSE. Occasionally, events affecting the value of foreign securities occur when the foreign market is closed and the NYSE is open. Principal Funds has adopted policies and procedures to "fair value" some or all securities held by a Fund if significant events occur after the close of the market on which the foreign securities are traded but before the Fund's NAV is calculated. Significant events can be specific to a single security or can include events that affect a particular foreign market or markets. A significant event can also include a general market movement in the U.S. securities markets. If Principal believes that the market value of any or all of the foreign securities is materially affected by such an event, the securities will be valued, and the Fund's NAV will be calculated, using the policy adopted by the Principal Funds. These fair valuation procedures are intended to discourage shareholders from investing in the Fund for the purpose of engaging in market timing or arbitrage transactions.
 
  The trading of foreign securities generally or in a particular country or countries may not take place on all days the NYSE is open, or may trade on days the NYSE is closed. Thus, the value of the foreign securities held by the Fund may change on days when shareholders are unable to purchase or redeem shares.
 
·      Certain securities issued by companies in emerging market countries may have more than one quoted valuation at any point in time. These may be referred to as local price and premium price. The premium price is often a negotiated price that may not consistently represent a price at which a specific transaction can be effected. The Fund has a policy to value such securities at a price at which the Sub-Advisor expects the securities may be sold.

PURCHASE OF FUND SHARES

Shares may be purchased:

·      via the internet.
  ·      standard method of accepting data for plans with fewer than 1,000 current and terminated (within the last five years) members.
  ·      available 7 days a week (7 a.m. to 9 p.m. Central Time).
·      using a modem.
  ·      plan contributions transferred electronically.
  ·      standard method of accepting data for plans with more than 1,000 current and terminated (within the last five years) members.
  ·      available 24 hours a day, 7 days a week.

To eliminate the need for safekeeping, Principal Funds will not issue certificates for shares. The Fund may periodically close to new purchases of shares or refuse any order to buy shares if Principal determines that doing so would be in the best interests of the Fund and its shareholders.

Principal may recommend to the Board, and the Board may elect, to close a fund to new and existing investors.

REDEMPTION OF FUND SHARES

Subject to any restrictions imposed by a plan, shares may be sold back to the Fund any day the NYSE is open. For more information about how to sell shares of the Fund, including any charges that a plan may impose, please consult the plan.

The Fund generally sends payment for shares sold the business day after the sell order is received. Under unusual circumstances, the Fund may suspend redemptions, or postpone payment for more than seven days, as permitted by federal securities law.

Distributions in Kind. Payment for shares of the Fund tendered for redemption is ordinarily made by check. However, the Fund may determine that it would be detrimental to the remaining shareholders of the Fund to make payment of a redemption order wholly or partly in cash. Under certain circumstances, therefore, the Fund may pay the redemption proceeds in whole or in part by a distribution "in kind" of securities from the Fund's portfolio in lieu of cash. If the Fund pays the redemption proceeds in kind, the redeeming shareholder might incur brokerage or other costs in selling the securities for cash. The Fund will value securities used to pay redemptions in kind using the same method the Fund uses to value its portfolio securities as described in this prospectus.

Redemption fees. The Fund board of directors has determined that it is not necessary to impose a fee upon the redemption of fund shares, because the Fund has adopted transfer restrictions as described in "Exchange of Fund Shares."

EXCHANGE OF FUND SHARES

An exchange between Funds is a redemption of shares of one Fund and a concurrent purchase of shares in another Fund with the redemption proceeds. A shareholder, including a beneficial owner of shares held in nominee name or a participant in a participant-directed employee benefit plan, may exchange Fund shares under certain circumstances. In addition to any restrictions an intermediary or an employee benefit plan imposes, Fund shares may be exchanged, without charge, for shares of any other Fund of Principal Funds, provided that:

·      the shareholder has not exchanged shares of the Fund within 30 days preceding the exchange, unless the shareholder is exchanging into the Money Market Fund,
·      the share class of such other Fund is available through the plan, and
·      the share class of such other Fund is available in the shareholder's state of residence.

All exchanges completed on the same day are considered a single exchange for purposes of this exchange limitation. In addition, the Fund will reject an order to purchase shares of any Fund, except shares of the Money Market Fund, if the shareholder redeemed shares from that Fund within the preceding 30-day period. The 30-day exchange or purchase restriction does not apply to exchanges or purchases made on a scheduled basis such as scheduled periodic portfolio rebalancing transactions.

If Fund shares are purchased through an intermediary that is unable or unwilling to impose the 30-day exchange restriction described above, Fund management may waive this restriction in lieu of the exchange limitation that the intermediary is able to impose if, in management's judgment, such limitation is reasonably likely to prevent excessive trading in Fund shares. In order to prevent excessive exchanges, and under other circumstances where the Fund Board of Directors or Principal believes it is in the best interests of the Fund, the Fund reserves the right to revise or terminate this exchange privilege, limit the amount or further limit the number of exchanges, reject any exchange or close an account.

FREQUENT PURCHASES AND REDEMPTIONS

The Fund is not designed for, and does not knowingly accommodate, frequent purchases and redemptions of fund shares by investors. If you intend to trade frequently and/or use market timing investment strategies, you should not purchase this Fund.

18  REDEMPTION OF FUND SHARES  Principal Funds, Inc. 
    1-800-547-7754 


Frequent purchases and redemptions pose a risk to the Funds because they may:

• Disrupt the management of the Funds by: 
        forcing the Funds to hold short-term (liquid) assets rather than investing for long term growth, which results in 
  lost investment opportunities for the Fund; and 
        causing unplanned portfolio turnover; 
• Hurt the portfolio performance of the Funds; and 
• Increase expenses of the Funds due to: 
        increased broker-dealer commissions and 
        increased recordkeeping and related costs. 

Certain Funds may be at greater risk of harm due to frequent purchases and redemptions. For example, those Funds that invest in foreign securities may appeal to investors attempting to take advantage of time-zone arbitrage.

The Fund has adopted procedures to "fair value" foreign securities under certain circumstances, which are intended, in part, to discourage excessive trading of shares of the Funds. The Board of Directors of the Fund has also adopted policies and procedures with respect to frequent purchases and redemptions of shares of the Funds. The Funds monitor trading activity to identify and take action against abuses. While our policies and procedures are designed to identify and protect against abusive trading practices, there can be no certainty that we will identify and prevent abusive trading in all instances. If we are not able to identify such excessive trading practices, the Funds may be negatively impacted and may cause investors to suffer the harms described. The potential negative impact and harms of undetected excessive trading in shares of the underlying Funds in which the Strategic Asset Management Portfolios invest could flow through to the Strategic Asset Management Portfolios as they would for any Fund shareholder. When we do identify abusive trading, we will apply our policies and procedures in a fair and uniform manner. If we are not able to identify such abusive trading practices, the abuses described above may negatively impact the Funds.

The Fund has adopted an exchange frequency restriction, described above in "Exchange of Fund Shares" to limit excessive trading in fund shares.

DIVIDENDS AND DISTRIBUTIONS

Dividends are based on estimates of income, expenses, and shareholder activity for the Fund. Actual income, expenses, and shareholder activity may differ from estimates; consequently, differences, if any, will be included in the calculation of subsequent dividends. The Funds pay their net investment income to shareholders of record on the business day prior to the payment date. The Fund declares dividends of its daily net investment income each day its shares are priced. On the last business day of each month the Fund will pay out its accumulated declared dividends.

Net realized capital gains, if any, are distributed annually. Generally the distribution is made on the fourth business day of December. Payments are made to shareholders of record on the business day prior to the payable date. Capital gains may be taxable at different rates, depending on the length of time that the Fund holds its assets.

Dividend and capital gains distributions will be reinvested, without a sales charge, in shares of the Fund from which the distribution is paid.

Generally, for federal income tax purposes, Fund distributions are taxable as ordinary income, except that any distributions of long-term capital gains will be taxed as such regardless of how long Fund shares have been held. Special tax rules apply to Fund distributions to retirement plans. A tax advisor should be consulted to determine the suitability of the Fund as an investment by such a plan and the tax treatment of distributions by the Fund. A tax advisor can also provide information on the potential impact of possible foreign, state, and local taxes. A Fund's investments in foreign securities may be subject to foreign withholding taxes. In that case, the Fund's yield on those securities would be decreased.

To the extent that distributions the Fund pays are derived from a source other than net income (such as a return of capital), a notice will be included in your quarterly statement pursuant to Section 19(a) of the Investment Company Act of 1940, as amended, and Rule 19a-1 disclosing the source of such distributions. Furthermore, such notices shall be

posted monthly on our web site at www.principal.com. You may request a copy of all such notices, free of charge, by telephoning 1-800-547-7754. The amounts and sources of distributions included in such notices are estimates only and you should not rely upon them for purposes of reporting income taxes. The Fund will send shareholders a Form 1099-DIV for the calendar year that will tell shareholders how to report these distributions for federal income tax purposes.

FUND ACCOUNT INFORMATION

Statements

Statements are sent each calendar quarter. The statements provide the number and value of shares owned by the plan, transactions during the quarter, dividends declared or paid, and other information.

This information may also be accessed by accessing www.principal.com.

Orders Placed by Intermediaries

Principal Funds may have an agreement with your intermediary, such as a broker-dealer, third party administrator, or trust company, that permits the intermediary to accept orders on behalf of the Fund until 3 p.m. Central Time. The agreement may include authorization for your intermediary to designate other intermediaries ("sub-designees") to accept orders on behalf of the Fund on the same terms that apply to the intermediary. In such cases, if your intermediary or a sub-designee receives your order in correct form by 3 p.m. Central Time, transmits it to the Fund and pays for it in accordance with the agreement, the Fund will price the order at the next net asset value per share it computes after your intermediary or sub-designee received your order. Note: The time at which the Fund prices orders and the time until which the Fund or your intermediary or sub-designee will accept orders may change in the case of an emergency or if the New York Stock Exchange closes at a time other than 3 p.m. Central Time.

Minimum Account Balance

Principal Funds reserves the right to set a minimum and redeem all shares in the Fund if the value of a plan's investments in the Fund is less than the minimum. Principal Funds has set the minimum at $2.5 million. The redemption proceeds would then be sent according to the directions of the appropriate plan fiduciary. If the Fund exercises this right, the plan sponsor will be notified that the redemption is going to be made. The plan will have 30 days to make an additional investment and bring plan assets up to the required minimum. The Fund reserves the right to change the minimum.

Reservation of Rights

Principal Funds reserves the right to amend or terminate the special plans described in this prospectus. In addition, Principal Funds reserves the right to change the share classes described herein. Shareholders will be notified of any such action to the extent required by law.

Multiple Translations

This prospectus may be translated into other languages. In the event of any inconsistencies or ambiguity as to the meaning of any word or phrase in a translation, the English text will prevail.

Procedures for Opening an Account

To help the government fight the funding of terrorism and money laundering activities, Federal law requires financial institutions to obtain, verify, and record information that identifies each person who opens an account. When you open an account, we will ask for your name, address, date of birth, and other information that will allow us to verify your identity. We may also ask to see your driver's license or other identifying documents.

If concerns arise with verification of your identification, no transactions, other than redemptions, will be permitted while we attempt to reconcile the concerns. If we are unable to verify your identify within 30 days of our receipt of your original purchase, the account(s) will be closed and redeemed in accordance with normal redemption procedures.

APPENDIX A

SUMMARY OF PRINCIPAL RISKS

The value of your investment in the Fund changes with the value of the investments held by the Fund. Many factors affect that value, and it is possible that you may lose money by investing in the Fund. Factors that may adversely affect the Fund as a whole are called "principal risks." The principal risks of investing in the Funds are stated above in the Fund's description. Each of these risks is summarized below. Additional information about the Fund, its investments, and the related risks is located under "Certain Investment Strategies and Related Risks" and in the Statement of Additional Information.

Derivatives Risk

Derivatives are investments whose values depend on or are derived from other securities or indexes. A fund's use of certain derivative instruments (such as options, futures, and swaps) could produce disproportionate gains or losses. Derivatives are generally considered more risky than direct investments and, in a down market, could become harder to value or sell at a fair price.

Fixed-Income Securities Risk

Fixed-income securities are generally subject to two principal types of risks: interest rate risk and credit quality risk.

Interest Rate Risk. Fixed-income securities are affected by changes in interest rates. When interest rates decline, the market value of the fixed-income securities generally can be expected to rise. Conversely, when interest rates rise, the market value of fixed-income securities generally can be expected to decline.

Credit Quality Risk. Fixed-income securities are subject to the risk that the issuer of the security will not repay all or a portion of the principal borrowed and will not make all interest payments. If the credit quality of a fixed income security deteriorates after a fund has purchased the security, the market value of the security may decrease and lead to a decrease in the value of the fund's investments. Lower quality and longer maturity bonds will be subject to greater credit risk and price fluctuations than higher quality and shorter maturity bonds. Bonds held by a fund may be affected by unfavorable political, economic, or government developments that could affect the repayment of principal or the payment of interest.

Portfolio Duration Risk

Portfolio duration is a measure of the expected life of a fixed-income security that is used to determine the sensitivity of a security's price to changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Prepayment Risk

Mortgage-backed and asset-backed securities are subject to prepayment risk. When interest rates decline, significant unscheduled payments may result. These prepayments must then be reinvested at lower rates. Prepayments may also shorten the effective maturities of these securities, especially during periods of declining interest rates. On the other hand, during periods of rising interest rates, a reduction in prepayments may increase the effective maturities of these securities, subjecting them to the risk of decline in market value in response to rising interest rates. This may increase the volatility of a fund.

Securities Lending Risk

The principal risk of securities lending is that the financial institution that borrows securities from the Fund could go bankrupt or otherwise default on its commitment under the securities lending agreement and the Fund might not be able to recover the loaned securities or their value.

Underlying Fund Risk

The Strategic Asset Management (“SAM”) Portfolios operate as funds of funds and invest principally in Underlying Funds. From time to time, an underlying fund may experience relatively large investments or redemptions by a fund of funds due to the reallocation or rebalancing of its assets. These transactions may have adverse effects on underlying

22  APPENDIX A  Principal Funds, Inc. 
    1-800-547-7754 


fund performance to the extent an underlying fund is required to sell portfolio securities to meet such redemptions, or to invest cash from such investments, at times it would not otherwise do so. This may be particularly important when a fund of funds owns a significant portion of an underlying fund. These transactions may also accelerate the realization of taxable income if sales of portfolio securities result in gains, and could increase transaction costs. In addition, when a fund of funds reallocates or redeems significant assets away from an underlying fund, the loss of assets to the underlying fund could result in increased expense ratios for that fund.

Principal is the advisor to the SAM Portfolios and each of the Underlying Funds. Edge Asset Management, Inc. (“Edge”) is the Sub-Advisor to the SAM Portfolios.

U.S. Government Securities Risk

U.S. government securities do not involve the degree of credit risk associated with investments in lower quality fixed-income securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from many other fixed-income securities. Like other fixed-income securities, the values of U.S. government securities change as interest rates fluctuate. Fluctuations in the value of a fund's securities do not affect interest income on securities already held by the fund but are reflected in the fund's price per share. Since the magnitude of these fluctuations generally is greater at times when a fund's average maturity is longer, under certain market conditions a fund may invest in short-term investments yielding lower current income rather than investing in higher yielding longer term securities.

U.S. Government Sponsored Securities Risk

A fund may invest in debt and mortgage-backed securities issued by government-sponsored enterprises such as the Federal Home Loan Mortgage Corporation, the Federal National Mortgage Association, and the Federal Home Loan Banks. Although the issuing agency, instrumentality, or corporation may be chartered or sponsored by the U.S. government, its securities are not issued or guaranteed by the U.S. Treasury.

DESCRIPTION OF THE FUNDS’ INVESTMENTS AND RISKS

Fund Policies

The investment objectives, investment strategies and the main risks of each Fund are described in the Prospectus. This Statement of Additional Information contains supplemental information about those strategies and risks and the types of securities the Sub-Advisor can select for each Fund. Additional information is also provided about the strategies that the Fund may use to try to achieve its objective.

The composition of each Fund and the techniques and strategies that the Sub-Advisor may use in selecting securities will vary over time. A Fund is not required to use all of the investment techniques and strategies available to it in seeking its goals.

Unless otherwise indicated, with the exception of the percentage limitations on borrowing, the restrictions apply at the time transactions are entered into. Accordingly, any later increase or decrease beyond the specified limitation, resulting from market fluctuations or in a rating by a rating service, does not require elimination of any security from the portfolio.

The investment objective of each Fund and, except as described below as "Fundamental Restrictions," the investment strategies described in this Statement of Additional Information and the prospectuses are not fundamental and may be changed by the Board of Directors without shareholder approval. The Fundamental Restrictions may not be changed without a vote of a majority of the outstanding voting securities of the affected Fund. The Investment Company Act of 1940, as amended, ("1940 Act") provides that "a vote of a majority of the outstanding voting securities" of a Fund means the affirmative vote of the lesser of 1) more than 50% of the outstanding shares or 2) 67% or more of the shares present at a meeting if more than 50% of the outstanding Fund shares are represented at the meeting in person or by proxy. Each share has one vote, with fractional shares voting proportionately. Shares of all classes of a Fund will vote together as a single class except when otherwise required by law or as determined by the Board of Directors.

With the exception of the diversification test required by the Internal Revenue Code, the Funds will not consider collateral held in connection with securities lending activities when applying any of the following fundamental restrictions or any other investment restriction set forth in each Fund's prospectus or Statement of Additional Information.

9)  Sell securities short (except where the Fund holds or has the right to obtain at no added cost a long position in 
  the securities sold that equals or exceeds the securities sold short). This restriction does not apply to the Core Plus 
  Bond Fund I. 

Non-Fundamental Restrictions

Each of these Funds has also adopted the following restrictions that are not fundamental policies and may be changed without shareholder approval. It is contrary to each Fund's present policy to:

1)  Invest more than 15% (10% in the case of the Money Market Fund) of its net assets in illiquid securities and in 
  repurchase agreements maturing in more than seven days except to the extent permitted by applicable law. 
 
2)  Pledge, mortgage, or hypothecate its assets, except to secure permitted borrowings. The deposit of underlying 
  securities and other assets in escrow and other collateral arrangements in connection with transactions in put or 
  call options, futures contracts, options on futures contracts, and over-the-counter swap contracts are not deemed 
  to be pledges or other encumbrances. 
 
3)  Invest in companies for the purpose of exercising control or management. 
 
4)  Invest more than 25% (35% for High Yield and Preferred Securities Funds) of its assets in foreign securities, except 
  that the Diversified International, Global Diversified Income, Global Real Estate Securities, International Emerging Markets,
  International Growth, International Value I, Money Market, and Global Equity Fund I each may invest up to 100%
  of its assets in foreign securities, the LargeCap S&P 500 Index, MidCap S&P 400 Index, and SmallCap S&P 600
  Index Funds each may invest in foreign securities to the extent that the relevant index is so invested, and the
  California Municipal, Government & High Quality Bond, Mortgage Securities, and Tax-Exempt Bond Funds
  may not invest in foreign securities. 
 
5)  Invest more than 5% of its total assets in real estate limited partnership interests (except the Global Diversified Income,
  Global Real Estate Securities and Real Estate Securities Funds). 
 
6)  Acquire securities of other investment companies in reliance on Section 12(d)(1)(F) or (G) of the 1940 Act, invest 
  more than 10% of its total assets in securities of other investment companies, invest more than 5% of its total 
  assets in the securities of any one investment company, or acquire more than 3% of the outstanding voting 
  securities of any one investment company except in connection with a merger, consolidation, or plan of 
  reorganization. The Fund may purchase securities of closed-end investment companies in the open market where 
  no underwriter or dealer's commission or profit, other than a customary broker's commission, is involved. 

Each Fund (except the Diversified International, Global Diversified Income, Income, International Emerging Markets, International Growth, and International Value I Funds) has also adopted the non-fundamental policy which requires it, under normal circumstances, to invest at least 80% of its net assets in the type of securities, industry or geographic region (as described in the prospectus) as suggested by the name of the Fund. The Fund will provide 60-days notice to shareholders prior to implementing a change in this policy for the Fund.

The Tax-Exempt Bond Fund has also adopted a fundamental policy which requires it, under normal circumstances, to invest at least 80% of its net assets in investments, the income from which is exempt from federal income tax or so that at least 80% of the income the Fund distributes will be exempt from federal income tax.

The California Municipal Fund has adopted a fundamental policy that requires it, under normal circumstances, to invest at least 80% of its net assets in investments the income from which is exempt from federal income tax and California state personal income tax or so that at least 80% of the income the Fund distributes will be exempt from federal income tax and California state personal income tax. The Fund also has adopted a non-fundamental policy that requires it, under normal circumstances, to invest at least 80% of its net assets in municipal obligations.

  or guaranteed by the U.S. Government or any of its agencies or instrumentalities, or securities of other investment 
  companies) if, as a result, a) more than 5% of the fund's total assets would be invested in the securities of that 
  issuer, or b) the fund would hold more than 10% of the outstanding voting securities of that issuer; 
 
2)  Issue senior securities, except in connection with the insurance program established by the fund pursuant to an 
  exemptive order issued by the Securities and Exchange Commission or as otherwise permitted under the 1940 
  Act.

  permitted by regulatory authority having jurisdiction, from time to time. 
 
4)  Underwrite securities issued by others, except to the extent that the Fund may be considered an underwriter within 
  the meaning of the Securities Act of 1933 in the disposition of restricted securities or in connection with 
  investments in other investment companies. 
 
5)  Purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of 
  its agencies or instrumentalities) if, as a result, more than 25% of the Fund's total assets would be invested in the 
  securities of companies whose principal business activities are in the same industry; 
 
6)  Purchase or sell real estate unless acquired as a result of ownership of securities or other instruments (but this 
  shall not prevent the Fund from investing in securities or other instruments backed by real estate or securities of 
  companies engaged in the real estate business). 
 
7)  Purchase or sell physical commodities unless acquired as a result of ownership of securities or other instruments 
  (but this shall not prevent the Fund from purchasing or selling options and futures contracts or from investing in 
  securities or other instruments backed by physical commodities). 
 
8)  Lend any security or make any other loan if, as a result, more than 33 1/3% of its total assets would be lent to other 
  parties, but this limitation does not apply to purchases of debt securities or to repurchase agreements, or to 
  acquisitions of loans, loan participations, or other forms of debt instruments. 

Non-Fundamental Restrictions

The Fund has also adopted the following restrictions that are not fundamental policies and may be changed without shareholder approval.

1)  The Fund does not currently intend to sell securities short, unless it owns or has the right to obtain securities 
  equivalent in kind and amount to the securities sold short, and provided that transactions in futures contracts and 
  options are not deemed to constitute selling securities short. 
 
2)  The Fund does not currently intend to purchase securities on margin, except that the Fund may obtain such short- 
  term credits as are necessary for the clearance of transactions, and provided that margin payments in connection 
  with futures contracts and options on futures contracts shall not constitute purchasing securities on margin. 
 
3)  The Fund may not borrow money, except as permitted under the 1940 Act, as interpreted, modified, or otherwise 
  permitted by regulatory authority having jurisdiction, from time to time.

    1-800-222-5852 


4)  The Fund does not currently intend to purchase any security if, as a result, more than 10% of its net assets would 
  be invested in securities that are deemed to be illiquid because they are subject to legal or contractual restrictions 
  on resale or because they cannot be sold or disposed of in the ordinary course of business at approximately the 
  prices at which they are valued. 
 
  For purposes of the Fund's illiquid securities limitation discussed above, if through a change in values, net assets, 
  or other circumstances, the Fund were in a position where more than 10% of its net assets were invested in illiquid 
  securities, it would consider appropriate steps to protect liquidity. 
 
5)  The Fund does not currently intend to acquire securities of other investment companies in reliance on Section 
  12(d)(1)(F) or (G) of the 1940 Act, invest more than 10% of its total assets in securities of other investment 
  companies, invest more than 5% of its total assets in the securities of any one investment company, or acquire 
  more than 3% of the outstanding voting securities of any one investment company except in connection with a 
  merger, consolidation or plan of reorganization. The Fund may purchase securities of closed-end investment 
  companies in the open market where no underwriter or dealer's commission or profit, other than a customary 
  broker's commission, is involved. 

In addition to the Fund's fundamental and non-fundamental limitations discussed above, the Fund has also adopted a non-fundamental policy which requires it, under normal circumstances, to invest at least 80% of its net assets in securities of medium market capitalization companies. The Fund will provide 60-days notice to shareholders prior to implementing a change in this policy for the Fund.

  pledges of assets. 
 
2)  Invest in companies for the purpose of exercising control or management. 

Investment Strategies and Risks

Restricted Securities

Generally, restricted securities are not readily marketable because they are subject to legal or contractual restrictions upon resale. They are sold only in a public offering with an effective registration statement or in a transaction that is exempt from the registration requirements of the Securities Act of 1933. When registration is required, a Fund may be obligated to pay all or part of the registration expenses and a considerable period may elapse between the time of the decision to sell and the time the Fund may be permitted to sell a security. If adverse market conditions were to develop during such a period, the Fund might obtain a less favorable price than existed when it decided to sell. Restricted securities and other securities not readily marketable are priced at fair value as determined in good faith by or under the direction of the Directors.

Each of the Funds has adopted investment restrictions that limit its investments in restricted securities or other illiquid securities up to 15% of its net assets (or, in the case of the Money Market Fund, 10%). The Directors have adopted procedures to determine the liquidity of Rule 4(2) short-term paper and of restricted securities under Rule 144A. Securities determined to be liquid under these procedures are excluded from the preceding investment restriction.

Foreign Securities

Foreign companies may not be subject to the same uniform accounting, auditing, and financial reporting practices as are required of U.S. companies. In addition, there may be less publicly available information about a foreign company than about a U.S. company. Securities of many foreign companies are less liquid and more volatile than securities of comparable U.S. companies. Commissions on foreign securities exchanges may be generally higher than those on U.S. exchanges.

Foreign markets also have different clearance and settlement procedures than those in U.S. markets. In certain markets there have been times when settlements have been unable to keep pace with the volume of securities

Principal Funds, Inc.  DESCRIPTION OF THE FUNDS’ INVESTMENTS AND RISKS  13 
www.principal.com     


transactions, making it difficult to conduct these transactions. Delays in settlement could result in temporary periods when a portion of a Fund's assets is not invested and is earning no return. If a Fund is unable to make intended security purchases due to settlement problems, the Fund may miss attractive investment opportunities. In addition, a Fund may incur a loss as a result of a decline in the value of its portfolio if it is unable to sell a security.

With respect to certain foreign countries, there is the possibility of expropriation or confiscatory taxation, political, or social instability, or diplomatic developments that could affect a Fund's investments in those countries. In addition, a Fund may also suffer losses due to nationalization, expropriation, or differing accounting practices and treatments. Investments in foreign securities are subject to laws of the foreign country that may limit the amount and types of foreign investments. Changes of governments or of economic or monetary policies, in the U.S. or abroad, changes in dealings between nations, currency convertibility, or exchange rates could result in investment losses for a Fund. Finally, even though certain currencies may be convertible into U.S. dollars, the conversion rates may be artificial relative to the actual market values and may be unfavorable to a Fund's investors.

Foreign securities are often traded with less frequency and volume, and therefore may have greater price volatility, than is the case with many U.S. securities. Brokerage commissions, custodial services, and other costs relating to investment in foreign countries are generally more expensive than in the U.S. Though the Funds intend to acquire the securities of foreign issuers where there are public trading markets, economic or political turmoil in a country in which a Fund has a significant portion of its assets or deterioration of the relationship between the U.S. and a foreign country may negatively impact the liquidity of a Fund's portfolio. The Fund may have difficulty meeting a large number of redemption requests. Furthermore, there may be difficulties in obtaining or enforcing judgments against foreign issuers.

Investments in companies of developing (also called “emerging”) countries are subject to higher risks than investments in companies in more developed countries. These risks include:

·      increased social, political, and economic instability;
·      a smaller market for these securities and low or nonexistent volume of trading that results in a lack of liquidity and in greater price volatility;
·      lack of publicly available information, including reports of payments of dividends or interest on outstanding securities;
·      foreign government policies that may restrict opportunities, including restrictions on investment in issuers or industries deemed sensitive to national interests;
·      relatively new capital market structure or market-oriented economy;
·      the possibility that recent favorable economic developments may be slowed or reversed by unanticipated political or social events in these countries;
·      restrictions that may make it difficult or impossible for the fund to vote proxies, exercise shareholder rights, pursue legal remedies, and obtain judgments in foreign courts; and
·      possible losses through the holding of securities in domestic and foreign custodial banks and depositories.

In addition, many developing countries have experienced substantial and, in some periods, extremely high rates of inflation for many years. Inflation and rapid fluctuations in inflation rates have had and may continue to have negative effects on the economies and securities markets of those countries.

Repatriation of investment income, capital and proceeds of sales by foreign investors may require governmental registration and/or approval in some developing countries. A Fund could be adversely affected by delays in or a refusal to grant any required governmental registration or approval for repatriation.

Further, the economies of developing countries generally are heavily dependent upon international trade and, accordingly, have been and may continue to be adversely affected by trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which they trade.

    1-800-222-5852 


Depositary Receipts

Depositary Receipts are generally subject to the same sort of risks as direct investments in a foreign country, such as, currency risk, political and economic risk, and market risk, because their values depend on the performance of a foreign security denominated in its home currency.

The Funds that may invest in foreign securities may invest in:

·      American Depositary Receipts ("ADRs") - receipts issued by an American bank or trust company evidencing ownership of underlying securities issued by a foreign issuer. They are designed for use in U.S. securities markets.
·      European Depositary Receipts ("EDRs") and Global Depositary Receipts ("GDRs") - receipts typically issued by a foreign financial institution to evidence an arrangement similar to that of ADRs.

Depositary Receipts may be issued by sponsored or unsponsored programs. In sponsored programs, an issuer has made arrangements to have its securities traded in the form of Depositary Receipts. In unsponsored programs, the issuer may not be directly involved in the creation of the program. Although regulatory requirements with respect to sponsored and unsponsored programs are generally similar, in some cases it may be easier to obtain financial information from an issuer that has participated in the creation of a sponsored program. Accordingly, there may be less information available regarding issuers of securities of underlying unsponsored programs, and there may not be a correlation between the availability of such information and the market value of the Depositary Receipts.

Securities of Smaller Companies

The Funds may invest in securities of companies with small- or mid-sized market capitalizations. Market capitalization is defined as total current market value of a company's outstanding common stock. Investments in companies with smaller market capitalizations may involve greater risks and price volatility (wide, rapid fluctuations) than investments in larger, more mature companies. Smaller companies may be less mature than older companies. At this earlier stage of development, the companies may have limited product lines, reduced market liquidity for their shares, limited financial resources or less depth in management than larger or more established companies. Small companies also may be less significant within their industries and may be at a competitive disadvantage relative to their larger competitors. While smaller companies may be subject to these additional risks, they may also realize more substantial growth than larger or more established companies. Small company stocks may decline in price as large company stocks rise, or rise in price while larger company stocks decline. Investors should therefore expect the net asset value of the Fund that invests a substantial portion of its assets in small company stocks may be more volatile than the shares of a Fund that invests solely in larger company stocks.

Unseasoned Issuers

The Funds may invest in the securities of unseasoned issuers. Unseasoned issuers are companies with a record of less than three years continuous operation, including the operation of predecessors and parents. Unseasoned issuers by their nature have only a limited operating history that can be used for evaluating the companies' growth prospects. As a result, investment decisions for these securities may place a greater emphasis on current or planned product lines and the reputation and experience of the company's management and less emphasis on fundamental valuation factors than would be the case for more mature growth companies. In addition, many unseasoned issuers also may be small companies and involve the risks and price volatility associated with smaller companies.

Spread Transactions, Options on Securities and Securities Indices, and Futures Contracts and Options on Futures Contracts The Funds (except the Principal LifeTime Funds and SAM Portfolios) may each engage in the practices described under this heading.

·      Spread Transactions. Each Fund may purchase covered spread options. Such covered spread options are not presently exchange listed or traded. The purchase of a spread option gives the Fund the right to put, or sell, a security that it owns at a fixed dollar spread or fixed yield spread in relationship to another security that the Fund does not own, but which is used as a benchmark. The risk to the Fund in purchasing covered spread options is the cost of the premium paid for the spread option and any transaction costs. In addition, there is no assurance that closing transactions will be available. The purchase of spread options can be used to protect each Fund against adverse changes in prevailing credit quality spreads, i.e., the yield spread between high quality and lower quality securities. The security covering the spread option is maintained in segregated accounts either with the Fund's
 
Principal Funds, Inc.  DESCRIPTION OF THE FUNDS’ INVESTMENTS AND RISKS  15 
www.principal.com     


  custodian or on the Fund's records. The Funds do not consider a security covered by a spread option to be "pledged" as that term is used in the Fund's policy limiting the pledging or mortgaging of assets.
 
·      Options on Securities and Securities Indices. Each Fund may write (sell) and purchase call and put options on securities in which it invests and on securities indices based on securities in which the Fund invests. The Funds may engage in these transactions to hedge against a decline in the value of securities owned or an increase in the price of securities which the Fund plans to purchase, or to generate additional revenue.
 
  ·      Writing Covered Call and Put Options. When a Fund writes a call option, it gives the purchaser of the option the right to buy a specific security at a specified price at any time before the option expires. When a Fund writes a put option, it gives the purchaser of the option the right to sell to the Fund a specific security at a specified price at any time before the option expires. In both situations, the Fund receives a premium from the purchaser of the option.
 
   The premium received by a Fund reflects, among other factors, the current market price of the underlying security, the relationship of the exercise price to the market price, the time period until the expiration of the option and interest rates. The premium generates additional income for the Fund if the option expires unexercised or is closed out at a profit. By writing a call, a Fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option, but it retains the risk of loss if the price of the security should decline. By writing a put, a Fund assumes the risk that it may have to purchase the underlying security at a price that may be higher than its market value at time of exercise.
 
   The Funds write only covered options and comply with applicable regulatory and exchange cover requirements. The Funds usually own the underlying security covered by any outstanding call option. With respect to an outstanding put option, each Fund deposits and maintains with its custodian or segregates on the Fund's records, cash, or other liquid assets with a value at least equal to the exercise price of the option.
 
   Once a Fund has written an option, it may terminate its obligation before the option is exercised. The Fund executes a closing transaction by purchasing an option of the same series as the option previously written. The Fund has a gain or loss depending on whether the premium received when the option was written exceeds the closing purchase price plus related transaction costs.
 
·      Purchasing Call and Put Options. When a Fund purchases a call option, it receives, in return for the premium it pays, the right to buy from the writer of the option the underlying security at a specified price at any time before the option expires. A Fund purchases call options in anticipation of an increase in the market value of securities that it intends ultimately to buy. During the life of the call option, the Fund is able to buy the underlying security at the exercise price regardless of any increase in the market price of the underlying security. In order for a call option to result in a gain, the market price of the underlying security must exceed the sum of the exercise price, the premium paid, and transaction costs.
 
  When a Fund purchases a put option, it receives, in return for the premium it pays, the right to sell to the writer of the option the underlying security at a specified price at any time before the option expires. A Fund purchases put options in anticipation of a decline in the market value of the underlying security. During the life of the put option, the Fund is able to sell the underlying security at the exercise price regardless of any decline in the market price of the underlying security. In order for a put option to result in a gain, the market price of the underlying security must decline, during the option period, below the exercise price enough to cover the premium and transaction costs.
 
  Once a Fund purchases an option, it may close out its position by selling an option of the same series as the option previously purchased. The Fund has a gain or loss depending on whether the closing sale price exceeds the initial purchase price plus related transaction costs.
 
·      Options on Securities Indices. Each Fund may purchase and sell put and call options on any securities index based on securities in which the Fund may invest. Securities index options are designed to reflect price fluctuations in a group of securities or segment of the securities market rather than price fluctuations in a single security. Options on securities indices are similar to options on securities, except that the exercise of securities index options requires
 
16  DESCRIPTION OF THE FUNDS’ INVESTMENTS AND RISKS  Principal Funds, Inc. 
    1-800-222-5852 


  cash payments and does not involve the actual purchase or sale of securities. The Funds engage in transactions in put and call options on securities indices for the same purposes as they engage in transactions in options on securities. When a Fund writes call options on securities indices, it holds in its portfolio underlying securities which, in the judgment of the Sub-Advisor, correlate closely with the securities index and which have a value at least equal to the aggregate amount of the securities index options.
 
·      Risks Associated with Option Transactions. An option position may be closed out only on an exchange that provides a secondary market for an option of the same series. The Funds generally purchase or write only those options for which there appears to be an active secondary market. However, there is no assurance that a liquid secondary market on an exchange exists for any particular option, or at any particular time. If a Fund is unable to effect closing sale transactions in options it has purchased, it has to exercise its options in order to realize any profit and may incur transaction costs upon the purchase or sale of underlying securities. If a Fund is unable to effect a closing purchase transaction for a covered option that it has written, it is not able to sell the underlying securities, or dispose of the assets held in a segregated account, until the option expires or is exercised. A Fund's ability to terminate option positions established in the over-the-counter market may be more limited than for exchange- traded options and may also involve the risk that broker-dealers participating in such transactions might fail to meet their obligations.
 
·      Futures Contracts and Options on Futures Contracts. Each Fund may purchase and sell financial futures contracts and options on those contracts. Financial futures contracts are commodities contracts based on financial instruments such as U.S. Treasury bonds or bills or on securities indices such as the S&P 500 Index. Futures contracts, options on futures contracts, and the commodity exchanges on which they are traded are regulated by the Commodity Futures Trading Commission. Through the purchase and sale of futures contracts and related options, a Fund may seek to hedge against a decline in the value of securities owned by the Fund or an increase in the price of securities that the Fund plans to purchase. Each Fund may enter into futures contracts and related options transactions both for hedging and non-hedging purposes.
 
·      Futures Contracts. When a Fund sells a futures contract based on a financial instrument, the Fund is obligated to deliver that kind of instrument at a specified future time for a specified price. When a Fund purchases that kind of contract, it is obligated to take delivery of the instrument at a specified time and to pay the specified price. In most instances, these contracts are closed out by entering into an offsetting transaction before the settlement date. The Fund realizes a gain or loss depending on whether the price of an offsetting purchase plus transaction costs are less or more than the price of the initial sale or on whether the price of an offsetting sale is more or less than the price of the initial purchase plus transaction costs. Although the Funds usually liquidate futures contracts on financial instruments, by entering into an offsetting transaction before the settlement date, they may make or take delivery of the underlying securities when it appears economically advantageous to do so.
 
  A futures contract based on a securities index provides for the purchase or sale of a group of securities at a specified future time for a specified price. These contracts do not require actual delivery of securities but result in a cash settlement. The amount of the settlement is based on the difference in value of the index between the time the contract was entered into and the time it is liquidated (at its expiration or earlier if it is closed out by entering into an offsetting transaction).
 
  When a Fund purchases or sells a futures contract, it pays a commission to the futures commission merchant through which the Fund executes the transaction. When entering into a futures transaction, the Fund does not pay the execution price, as it does when it purchases a security, or a premium, as it does when it purchases an option. Instead, the Fund deposits an amount of cash or other liquid assets (generally about 5% of the futures contract amount) with its futures commission merchant. This amount is known as "initial margin." In contrast to the use of margin account to purchase securities, the Fund's deposit of initial margin does not constitute the borrowing of money to finance the transaction in the futures contract. The initial margin represents a good faith deposit that helps assure the Fund's performance of the transaction. The futures commission merchant returns the initial margin to the Fund upon termination of the futures contract if the Fund has satisfied all its contractual obligations.
 
  Subsequent payments to and from the futures commission merchant, known as "variation margin," are required to be made on a daily basis as the price of the futures contract fluctuates, a process known as "marking to market."

  The fluctuations make the long or short positions in the futures contract more or less valuable. If the position is closed out by taking an opposite position prior to the settlement date of the futures contract, a final determination of variation margin is made. Any additional cash is required to be paid to or released by the broker and the Fund realizes a loss or gain.
 
  In using futures contracts, the Fund may seek to establish more certainly, than would otherwise be possible, the effective price of or rate of return on portfolio securities or securities that the Fund proposes to acquire. A Fund, for example, sells futures contracts in anticipation of a rise in interest rates that would cause a decline in the value of its debt investments. When this kind of hedging is successful, the futures contract increases in value when the Fund's debt securities decline in value and thereby keeps the Fund's net asset value from declining as much as it otherwise would. A Fund may also sell futures contracts on securities indices in anticipation of or during a stock market decline in an endeavor to offset a decrease in the market value of its equity investments. When a Fund is not fully invested and anticipates an increase in the cost of securities it intends to purchase, it may purchase financial futures contracts. When increases in the prices of equities are expected, a Fund may purchase futures contracts on securities indices in order to gain rapid market exposure that may partially or entirely offset increases in the cost of the equity securities it intends to purchase.
 
·      Options on Futures Contracts. The Funds may also purchase and write call and put options on futures contracts. A call option on a futures contract gives the purchaser the right, in return for the premium paid, to purchase a futures contract (assume a long position) at a specified exercise price at any time before the option expires. A put option gives the purchaser the right, in return for the premium paid, to sell a futures contract (assume a short position), for specified exercise price, at any time before the option expires.
 
  Upon the exercise of a call, the writer of the option is obligated to sell the futures contract (to deliver a long position to the option holder) at the option exercise price, which will presumably be lower than the current market price of the contract in the futures market. Upon exercise of a put, the writer of the option is obligated to purchase the futures contract (deliver a short position to the option holder) at the option exercise price, which will presumably be higher than the current market price of the contract in the futures market. However, as with the trading of futures, most options are closed out prior to their expiration by the purchase or sale of an offsetting option at a market price that reflects an increase or a decrease from the premium originally paid. Options on futures can be used to hedge substantially the same risks addressed by the direct purchase or sale of the underlying futures contracts. For example, if a Fund anticipates a rise in interest rates and a decline in the market value of the debt securities in its portfolio, it might purchase put options or write call options on futures contracts instead of selling futures contracts.
 
  If a Fund purchases an option on a futures contract, it may obtain benefits similar to those that would result if it held the futures position itself. But in contrast to a futures transaction, the purchase of an option involves the payment of premium in addition to transaction costs. In the event of an adverse market movement, however, the Fund is not subject to a risk of loss on the option transaction beyond the price of the premium it paid plus its transaction costs.
 
  When a Fund writes an option on a futures contract, the premium paid by the purchaser is deposited with the Fund's custodian. The Fund must maintain with its futures commission merchant all or a portion of the initial margin requirement on the underlying futures contract. It assumes a risk of adverse movement in the price of the underlying futures contract comparable to that involved in holding a futures position. Subsequent payments to and from the futures commission merchant, similar to variation margin payments, are made as the premium and the initial margin requirements are marked to market daily. The premium may partially offset an unfavorable change in the value of portfolio securities, if the option is not exercised, or it may reduce the amount of any loss incurred by the Fund if the option is exercised.
 
·      Risks Associated with Futures Transactions. There are a number of risks associated with transactions in futures contracts and related options. A Fund's successful use of futures contracts is subject to the ability of the Sub- Advisor to predict correctly the factors affecting the market values of the Fund's portfolio securities. For example, if Fund is hedged against the possibility of an increase in interest rates which would adversely affect debt securities held by the Fund and the prices of those debt securities instead increases, the Fund loses part or all of the benefit of the increased value of its securities it hedged because it has offsetting losses in its futures positions. Other risks include imperfect correlation between price movements in the financial instrument or securities index underlying

  the futures contract, on the one hand, and the price movements of either the futures contract itself or the securities held by the Fund, on the other hand. If the prices do not move in the same direction or to the same extent, the transaction may result in trading losses.
 
  Prior to exercise or expiration, a position in futures may be terminated only by entering into a closing purchase or sale transaction. This requires a secondary market on the relevant contract market. The Fund enters into a futures contract or related option only if there appears to be a liquid secondary market. There can be no assurance, however, that such a liquid secondary market exists for any particular futures contract or related option at any specific time. Thus, it may not be possible to close out a futures position once it has been established. Under such circumstances, the Fund continues to be required to make daily cash payments of variation margin in the event of adverse price movements. In such situations, if the Fund has insufficient cash, it may be required to sell portfolio securities to meet daily variation margin requirements at a time when it may be disadvantageous to do so. In addition, the Fund may be required to perform under the terms of the futures contracts it holds. The inability to close out futures positions also could have an adverse impact on the Fund's ability effectively to hedge its portfolio.
 
  Most United States futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. This daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day's settlement price at the end of a trading session. Once the daily limit has been reached in a particular type of contract, no more trades may be made on that day at a price beyond that limit. The daily limit governs only price movements during a particular trading day and therefore does not limit potential losses because the limit may prevent the liquidation of unfavorable positions. Futures contract prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting some futures traders to substantial losses.
 
·      Limitations on the Use of Futures and Options on Futures Contracts. Each Fund intends to come within an exclusion from the definition of "commodity pool operator" provided by Commodity Futures Trading Commission regulations.
 
  Each Fund may enter into futures contracts and related options transactions, for hedging purposes and for other appropriate risk management purposes, and to modify the Fund's exposure to various currency, equity, or fixed- income markets. Each Fund may engage in speculative futures trading. When using futures contracts and options on futures contracts for hedging or risk management purposes, each Fund determines that the price fluctuations in the contracts and options are substantially related to price fluctuations in securities held by the Fund or which it expects to purchase. In pursuing traditional hedging activities, each Fund may sell futures contracts or acquire puts to protect against a decline in the price of securities that the Fund owns. Each Fund may purchase futures contracts or calls on futures contracts to protect the Fund against an increase in the price of securities the Fund intends to purchase before it is in a position to do so.
 
  When a Fund purchases a futures contract, or purchases a call option on a futures contract, it segregates portfolio assets, which must be liquid and marked to the market daily, in a segregated account. The amount so segregated plus the amount of initial margin held for the account of its futures commission merchant equals the market value of the futures contract.
 
  With respect to futures contracts that are not legally required to “cash settle,” a Fund may cover the open position by setting aside or “earmarking” liquid assets in an amount equal to the market value of the futures contract. With respect to futures that are required to “cash settle,” however, a Fund is permitted to set aside or “earmark” liquid assets in an amount equal to the Fund’s daily marked to market (net) obligation, if any (in other words, the Fund’s daily net liability, if any) rather than the market value of the futures contract. By setting aside or “earmarking” assets equal to only its net obligation under cash-settled futures, a Fund will have the ability to utilize these contracts to a greater extent than if the Fund were required to segregate or “earmark” assets equal to the full market value of the futures contract.

Ultra Short Bond, and West Coast Equity Funds each may invest a portion of its assets in bonds that are rated below investment grade (i.e., bonds rated BB or lower by Standard & Poor's Ratings Services or Ba or lower by Moody's Investors Service, Inc. (commonly known as "junk bonds")). Lower rated bonds involve a higher degree of credit risk, which is the risk that the issuer will not make interest or principal payments when due. In the event of an unanticipated default, a Fund would experience a reduction in its income and could expect a decline in the market value of the bonds so affected. The Bond & Mortgage Securities, Core Plus Bond I, Equity Income, Government & High Quality Bond, High Quality Intermediate-Term Bond, High Yield, Income, MidCap Stock, Short-Term Bond, Short-Term Income, and West Coast Equity Funds may also invest in unrated bonds of foreign and domestic issuers. Unrated bonds, while not necessarily of lower quality than rated bonds, may not have as broad a market. Because of the size and perceived demand of the issue, among other factors, certain municipalities may not incur the expense of obtaining a rating. The Sub-Advisor will analyze the creditworthiness of the issuer, as well as any financial institution or other party responsible for payments on the bond, in determining whether to purchase unrated bonds. Unrated bonds will be included in the limitation each Fund has with regard to high yield bonds unless the Sub-Advisor deems such securities to be the equivalent of investment grade bonds.

Mortgage- and Asset-Backed Securities

The yield characteristics of the mortgage- and asset-backed securities in which the Funds may invest differ from those of traditional debt securities. Among the major differences are that the interest and principal payments are made more frequently on mortgage- and asset-backed securities (usually monthly) and that principal may be prepaid at any time because the underlying mortgage loans or other assets generally may be prepaid at any time. As a result, if the Fund purchases those securities at a premium, a prepayment rate that is faster than expected will reduce their yield, while a prepayment rate that is slower than expected will have the opposite effect of increasing yield. If the Fund purchases these securities at a discount, faster than expected prepayments will increase their yield, while slower than expected prepayments will reduce their yield. Amounts available for reinvestment by the Fund are likely to be greater during a period of declining interest rates and, as a result, are likely to be reinvested at lower interest rates than during a period of rising interest rates.

In general, the prepayment rate for mortgage-backed securities decreases as interest rates rise and increases as interest rates fall. However, rising interest rates will tend to decrease the value of these securities. In addition, an increase in interest rates may affect the volatility of these securities by effectively changing a security that was considered a short-term security at the time of purchase into a long-term security. Long-term securities generally fluctuate more widely in response to changes in interest rates than short- or medium-term securities.

The market for privately issued mortgage- and asset-backed securities is smaller and less liquid than the market for U.S. government mortgage-backed securities. A collateralized mortgage obligation may be structured in a manner that provides a wide variety of investment characteristics (yield, effective maturity, and interest rate sensitivity). As market conditions change, and especially during periods of rapid market interest rate changes, the ability of a collateralized mortgage obligation to provide the anticipated investment characteristics may be greatly diminished. Increased market volatility and/or reduced liquidity may result.

Real Estate Investment Trusts (“REITs”)

REITs are pooled investment vehicles that invest in income producing real estate, real estate related loans, or other types of real estate interests. U.S. REITs are allowed to eliminate corporate level federal tax so long as they meet certain requirements of the Internal Revenue Code. Foreign REITs ("REIT-like") entities may have similar tax treatment in their respective countries. Equity real estate investment trusts own real estate properties, while mortgage real estate investment trusts make construction, development, and long-term mortgage loans. Their value may be affected by changes in the underlying property of the trusts, the creditworthiness of the issuer, property taxes, interest rates, and tax and regulatory requirements, such as those relating to the environment. Both types of trusts are not diversified, are dependent upon management skill, are subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, and the possibility of failing to qualify for tax-free status of income under the Internal Revenue Code and failing to maintain exemption from the 1940 Act. In addition, foreign REIT-like entities will be subject to foreign securities risks. (See "Foreign Securities")

Zero-Coupon Securities

20  DESCRIPTION OF THE FUNDS’ INVESTMENTS AND RISKS  Principal Funds, Inc. 
    1-800-222-5852 


The Funds may invest in zero-coupon securities. Zero-coupon securities have no stated interest rate and pay only the principal portion at a stated date in the future. They usually trade at a substantial discount from their face (par) value. Zero-coupon securities are subject to greater market value fluctuations in response to changing interest rates than debt obligations of comparable maturities that make distributions of interest in cash.

Securities Lending

All Funds may lend their portfolio securities. None of the Funds will lend its portfolio securities if as a result the aggregate of such loans made by the Fund would exceed the limits established by the 1940 Act. Portfolio securities may be lent to unaffiliated broker-dealers and other unaffiliated qualified financial institutions provided that such loans are callable at any time on not more than five business days' notice and that cash or other liquid assets equal to at least 100% of the market value of the securities loaned, determined daily, is deposited by the borrower with the Fund and is maintained each business day. While such securities are on loan, the borrower pays the Fund any income accruing thereon. The Fund may invest any cash collateral, thereby earning additional income, and may receive an agreed-upon fee from the borrower. Borrowed securities must be returned when the loan terminates. Any gain or loss in the market value of the borrowed securities that occurs during the term of the loan belongs to the Fund and its shareholders. A Fund pays reasonable administrative, custodial, and other fees in connection with such loans and may pay a negotiated portion of the interest earned on the cash or government securities pledged as collateral to the borrower or placing broker. A Fund does not normally retain voting rights attendant to securities it has lent, but it may call a loan of securities in anticipation of an important vote.

Short Sales

The Core Plus Bond Fund I may engage in “short sales.” A short sale involves the sale by the Fund of a security that it does not own with the hope of purchasing the same security at a later date at a lower price. The Fund may also enter into a short derivative position through a futures contract or swap agreement. If the price of the security or derivative has increased during this time, then the Fund will incur a loss equal to the increase in price from the time that the short sale was entered into plus any premiums and interest paid to the third party. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the investment. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund.

Each Fund, other than the Principal LifeTime Funds and the SAM Portfolios, may engage in “short sales against the box.” This technique involves selling either a security owned by the Fund, or a security equivalent in kind and amount to the security sold short that the Fund has the right to obtain, for delivery at a specified date in the future. A Fund may enter into a short sale against the box to hedge against anticipated declines in the market price of portfolio securities. If the value of the securities sold short increases prior to the scheduled delivery date, a Fund loses the opportunity to participate in the gain.

Forward Foreign Currency Exchange Contracts

The Funds may, but are not obligated to, enter into forward foreign currency exchange contracts. Currency transactions include forward currency contracts and exchange listed or over-the-counter options on currencies. A forward currency contract involves a privately negotiated obligation to purchase or sell a specific currency at a specified future date at a price set at the time of the contract.

The typical use of a forward contract is to "lock in" the price of a security in U.S. dollars or some other foreign currency which a Fund is holding in its portfolio. By entering into a forward contract for the purchase or sale, for a fixed amount of dollars or other currency, of the amount of foreign currency involved in the underlying security transactions, a Fund may be able to protect itself against a possible loss resulting from an adverse change in the relationship between the U.S. dollar or other currency which is being used for the security purchase and the foreign currency in which the security is denominated in or exposed to during the period between the date on which the security is purchased or sold and the date on which payment is made or received.

The Sub-Advisor also may from time to time utilize forward contracts for other purposes. For example, they may be used to hedge a foreign security held in the portfolio or a security which pays out principal tied to an exchange rate between the U.S. dollar and a foreign currency, against a decline in value of the applicable foreign currency. They also may be used to lock in the current exchange rate of the currency in which those securities anticipated to be purchased

Principal Funds, Inc.  DESCRIPTION OF THE FUNDS’ INVESTMENTS AND RISKS  21

are denominated in or exposed to. At times, a Fund may enter into "cross-currency" hedging transactions involving currencies other than those in which securities are held or proposed to be purchased are denominated.

A Fund segregates liquid assets in an amount equal to its daily marked-to-market (net) obligation (i.e., its daily net liability, if any) with respect to forward currency contracts. It should be noted that the use of forward foreign currency exchange contracts does not eliminate fluctuations in the underlying prices of the securities. It simply establishes a rate of exchange between the currencies that can be achieved at some future point in time. Additionally, although such contracts tend to minimize the risk of loss due to a decline in the value of the hedged currency, they also tend to limit any potential gain that might result if the value of the currency increases.

Currency hedging involves some of the same risks and considerations as other transactions with similar instruments. Currency transactions can result in losses to a Fund if the currency being hedged fluctuates in value to a degree or in a direction that is not anticipated. Further, the risk exists that the perceived linkage between various currencies may not be present or may not be present during the particular time that a Fund is engaging in proxy hedging. Currency transactions are also subject to risks different from those of other portfolio transactions. Because currency control is of great importance to the issuing governments and influences economic planning and policy, purchases and sales of currency and related instruments can be adversely affected by government exchange controls, limitations or restrictions on repatriation of currency, and manipulations or exchange restrictions imposed by governments. These forms of governmental actions can result in losses to a Fund if it is unable to deliver or receive currency or monies in settlement of obligations. They could also cause hedges the Fund has entered into to be rendered useless, resulting in full currency exposure as well as incurring transaction costs. Currency exchange rates may also fluctuate based on factors extrinsic to a country's economy. Buyers and sellers of currency forward contracts are subject to the same risks that apply to the use of forward contracts generally. Further, settlement of a currency forward contract for the purchase of most currencies must occur at a bank based in the issuing nation. The ability to establish and close out positions on trading options on currency futures contracts is subject to the maintenance of a liquid market that may not always be available.

Moreover, a Fund bears the risk of loss of the amount expected to be received under a forward contract in the event of the default as bankruptcy of a forward counterparty.

Repurchase and Reverse Repurchase Agreements, Mortgage Dollar Rolls and Sale-Buybacks

The Funds may invest in repurchase and reverse repurchase agreements. In a repurchase agreement, a Fund purchases a security and simultaneously commits to resell that security to the seller at an agreed upon price on an agreed upon date within a number of days (usually not more than seven) from the date of purchase. The resale price consists of the purchase price plus an amount that is unrelated to the coupon rate or maturity of the purchased security. A repurchase agreement involves the obligation of the seller to pay the agreed upon price, which obligation is in effect secured by the value (at least equal to the amount of the agreed upon resale price and marked-to-market daily) of the underlying security or "collateral." A risk associated with repurchase agreements is the failure of the seller to repurchase the securities as agreed, which may cause a Fund to suffer a loss if the market value of such securities declines before they can be liquidated on the open market. In the event of bankruptcy or insolvency of the seller, a Fund may encounter delays and incur costs in liquidating the underlying security. Repurchase agreements that mature in more than seven days are subject to each Fund's limit on illiquid investments. While it is not possible to eliminate all risks from these transactions, it is the policy of the Fund to limit repurchase agreements to those parties whose creditworthiness has been reviewed and found satisfactory by the Sub-Advisor.

A Fund may use reverse repurchase agreements, mortgage dollar rolls, and economically similar transactions to obtain cash to satisfy unusually heavy redemption requests or for other temporary or emergency purposes without the necessity of selling portfolio securities, or to earn additional income on portfolio securities, such as Treasury bills or notes. In a reverse repurchase agreement, a Fund sells a portfolio security to another party, such as a bank or broker-dealer, in return for cash and agrees to repurchase the instrument at a particular price and time. While a reverse repurchase agreement is outstanding, a Fund will maintain cash or appropriate liquid assets to cover its obligation under the agreement. The Fund will enter into reverse repurchase agreements only with parties that the Sub-Advisor deems creditworthy. Using reverse repurchase agreements to earn additional income involves the risk that the interest earned on the invested proceeds is less than the expense of the reverse repurchase agreement transaction. This

technique may also have a leveraging effect on the Fund, although the Fund's intent to segregate assets in the amount of the reverse repurchase obligation minimizes this effect.

A "mortgage dollar roll" is similar to a reverse repurchase agreement in certain respects. In a "dollar roll" transaction a Fund sells a mortgage-related security, such as a security issued by the Government National Mortgage Association, to a dealer and simultaneously agrees to repurchase a similar security (but not the same security) in the future at a pre-determined price. A dollar roll can be viewed, like a reverse repurchase agreement, as a collateralized borrowing in which a Fund pledges a mortgage-related security to a dealer to obtain cash. Unlike in the case of reverse repurchase agreements, the dealer with which a Fund enters into a dollar roll transaction is not obligated to return the same securities as those originally sold by the Fund, but only securities which are "substantially identical." To be considered "substantially identical," the securities returned to a Fund generally must: 1) be collateralized by the same types of underlying mortgages; 2) be issued by the same agency and be part of the same program; 3) have a similar original stated maturity; 4) have identical net coupon rates; 5) have similar market yields (and therefore price); and 6) satisfy "good delivery" requirements, meaning that the aggregate principal amounts of the securities delivered and received back must be within 0.01% of the initial amount delivered.

A Fund's obligations under a dollar roll agreement must be covered by segregated liquid assets equal in value to the securities subject to repurchase by the Fund.

A Fund also may effect simultaneous purchase and sale transactions that are known as "sale-buybacks." A sale-buyback is similar to a reverse repurchase agreement, except that in a sale-buyback, the counterparty who purchases the security is entitled to receive any principal or interest payments made on the underlying security pending settlement of the Fund's repurchase of the underlying security. A Fund's obligations under a sale-buyback typically would be offset by liquid assets equal in value to the amount of the Fund's forward commitment to repurchase the subject security.

Swap Agreements and Options on Swap Agreements

Each Fund (except Money Market Fund) may engage in swap transactions, including, but not limited to, swap agreements on interest rates, security or commodity indexes, specific securities and commodities, and credit and event-linked swaps, to the extent permitted by its investment restrictions. To the extent a Fund may invest in foreign currency-denominated securities, it may also invest in currency exchange rate swap agreements. A Fund may also enter into options on swap agreements ("swap options").

A Fund may enter into swap transactions for any legal purpose consistent with its investment objectives and policies, such as for the purpose of attempting to obtain or preserve a particular return or spread at a lower cost than obtaining a return or spread through purchases and/or sales of instruments in other markets, to protect against currency fluctuations, as a duration management technique, to protect against any increase in the price of securities a Fund anticipates purchasing at a later date, or to gain exposure to certain markets in the most economical way possible.

Swap agreements are two party contracts entered into primarily by institutional investors for periods ranging from a few weeks to more than one year. In a standard "swap" transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments, which may be adjusted for an interest factor. The gross returns to be exchanged or "swapped" between the parties are generally calculated with respect to a "notional amount," i.e., the return on or increase in value of a particular dollar amount invested at a particular interest rate, in a particular foreign currency, or in a "basket" of securities or commodities representing a particular index. Forms of swap agreements include interest rate caps, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate, or "cap"; interest rate floors, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates fall below a specified rate, or "floor"; and interest rate collars, under which a party sells a cap and purchases a floor or vice versa in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels. Consistent with a Fund's investment objectives and general investment policies, certain of the Funds may invest in commodity swap agreements. For example, an investment in a commodity swap agreement may involve the exchange of floating-rate interest payments for the total return on a commodity index. In a total return commodity swap, a Fund will receive the price appreciation of a commodity index, a portion of the index, or a single commodity in exchange for paying an agreed-upon fee. If the commodity swap is for one period, a Fund may

Principal Funds, Inc.  DESCRIPTION OF THE FUNDS’ INVESTMENTS AND RISKS  23 
www.principal.com     


pay a fixed fee, established at the outset of the swap. However, if the term of the commodity swap is for more than one period, with interim swap payments, a Fund may pay an adjustable or floating fee. With a "floating" rate, the fee may be pegged to a base rate, such as the London Interbank Offered Rate, and is adjusted each period. Therefore, if interest rates increase over the term of the swap contract, a Fund may be required to pay a higher fee at each swap reset date.

A Fund may enter into credit default swap agreements. The "buyer" in a credit default contract is obligated to pay the "seller" a periodic stream of payments over the term of the contract provided that no event of default on an underlying reference obligation has occurred. If an event of default occurs, the seller must pay the buyer the full notional value, or "par value," of the reference obligation in exchange for the reference obligation. A Fund may be either the buyer or seller in a credit default swap transaction. If a Fund is a buyer and no event of default occurs, the Fund will lose its investment and recover nothing. However, if an event of default occurs, the Fund (if the buyer) will receive the full notional value of the reference obligation that may have little or no value. As a seller, a Fund receives a fixed rate of income throughout the term of the contract, which typically is between six months and three years, provided that there is no default event. If an event of default occurs, the seller must pay the buyer the full notional value of the reference obligation.

A swap option is a contract that gives a counterparty the right (but not the obligation) in return for payment of a premium, to enter into a new swap agreement or to shorten, extend, cancel, or otherwise modify an existing swap agreement, at some designated future time on specified terms. Each Fund (except Money Market Fund) may write (sell) and purchase put and call swap options. Most swap agreements entered into by the Funds would calculate the obligations of the parties to the agreement on a "net basis." Consequently, a Fund's current obligations (or rights) under a swap agreement will generally be equal only to the net amount to be paid or received under the agreement based on the relative values of the positions held by each party to the agreement (the "net amount"). A Fund's current obligations under a swap agreement will be accrued daily (offset against any amounts owed to the Fund) and any accrued but unpaid net amounts owed to a swap counterparty will be covered by the segregation of assets determined to be liquid by the Manager or Sub-Advisor in accordance with procedures established by the Board of Directors, to avoid any potential leveraging of the Fund's portfolio. Obligations under swap agreements so covered will not be construed to be "senior securities" for purposes of the Fund's investment restriction concerning senior securities. Each Fund will not enter into a swap agreement with any single party if the net amount owed or to be received under existing contracts with that party would exceed 5% of the Fund's total assets.

Whether a Fund's use of swap agreements or swap options will be successful in furthering its investment objective of total return will depend on the ability of the Fund's Manager or Sub-Advisor to predict correctly whether certain types of investments are likely to produce greater returns than other investments. Because they are two party contracts and because they may have terms of greater than seven days, swap agreements may be considered to be illiquid. Moreover, a Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. The Funds will enter into swap agreements only with counterparties that present minimal credit risks, as determined by the Fund's Manager or Sub-Advisor. Certain restrictions imposed on the Funds by the Internal Revenue Code may limit the Funds' ability to use swap agreements. The swaps market is a relatively new market and is largely unregulated. It is possible that developments in the swaps market, including potential government regulation, could adversely affect a Fund's ability to terminate existing swap agreements or to realize amounts to be received under such agreements.

Depending on the terms of the particular option agreement, a Fund will generally incur a greater degree of risk when it writes a swap option than it will incur when it purchases a swap option. When a Fund purchases a swap option, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. However, when a Fund writes a swap option, upon exercise of the option the Fund will become obligated according to the terms of the underlying agreement.

Liquidity. Some swap markets have grown substantially in recent years with a large number of banks and investment banking firms acting both as principals and as agents utilizing standardized swap documentation. As a result, these swap markets have become relatively liquid.

24  DESCRIPTION OF THE FUNDS’ INVESTMENTS AND RISKS  Principal Funds, Inc. 
    1-800-222-5852 


The liquidity of swap agreements will be determined by the Manager or Sub-Advisor based on various factors, including:

·      the frequency of trades and quotations,
·      the number of dealers and prospective purchasers in the marketplace,
·      dealer undertakings to make a market,
·      the nature of the security (including any demand or tender features), and
·      the nature of the marketplace for trades (including the ability to assign or offset a portfolio's rights and obligations relating to the investment).

Such determination will govern whether a swap will be deemed to be within each Fund's restriction on investments in illiquid securities.

For purposes of applying the Funds' investment policies and restrictions (as stated in the Prospectuses and this Statement of Additional Information) swap agreements are generally valued by the Funds at market value. In the case of a credit default swap sold by a Fund (i.e., where the Fund is selling credit default protection), however, the Fund will value the swap at its notional amount. The manner in which the Funds value certain securities or other instruments for purposes of applying investment policies and restrictions may differ from the manner in which those investments are valued by other types of investors.

When-Issued, Delayed Delivery, and Forward Commitment Transactions

Each of the Funds may purchase or sell securities on a when-issued, delayed delivery, or forward commitment basis. When such purchases are outstanding, the Fund will segregate until the settlement date assets determined to be liquid by the Sub-Advisor in accordance with procedures established by the Board of Directors, in an amount sufficient to meet the purchase price. Typically, no income accrues on securities a Fund has committed to purchase prior to the time delivery of the securities is made, although a Fund may earn income on securities it has segregated.

When purchasing a security on a when-issued, delayed delivery, or forward commitment basis, the Fund assumes the rights and risks of ownership of the security, including the risk of price and yield fluctuations, and takes such fluctuations into account when determining its net asset value. Because the Fund is not required to pay for the security until the delivery date, these risks are in addition to the risks associated with the Fund's other investments. If the Fund remains substantially fully invested at a time when when-issued, delayed delivery, or forward commitment purchases are outstanding, the purchases may result in a form of leverage.

When the Fund has sold a security on a when-issued, delayed delivery, or forward commitment basis, the Fund does not participate in future gains or losses with respect to the security. If the other party to a transaction fails to deliver or pay for the securities, the Fund could miss a favorable price or yield opportunity or could suffer a loss. A Fund may dispose of or renegotiate a transaction after it is entered into, and may sell when-issued, delayed delivery, or forward commitment securities before they are delivered, which may result in a capital gain or loss. There is no percentage limitation on the extent to which the Funds may purchase or sell securities on a when-issued, delayed delivery, or forward commitment basis.

Money Market Instruments/Temporary Defensive Position

The Money Market Fund invests all of its available assets in money market instruments maturing in 397 days or less. In addition, all of the Funds may make money market investments (cash equivalents), without limit, pending other investment or settlement, for liquidity, or in adverse market conditions. Following are descriptions of the types of money market instruments that the Funds may purchase:

·      U.S. Government Securities - Securities issued or guaranteed by the U.S. government, including treasury bills, notes, and bonds.
·      U.S. Government Agency Securities - Obligations issued or guaranteed by agencies or instrumentalities of the U.S. government.
  ·      U.S. agency obligations include, but are not limited to, the Bank for Cooperatives, Federal Home Loan Banks, and Federal Intermediate Credit Banks.
 
Principal Funds, Inc.  DESCRIPTION OF THE FUNDS’ INVESTMENTS AND RISKS  25 
www.principal.com     


·      U.S. instrumentality obligations include, but are not limited to, the Export-Import Bank, Federal Home Loan Mortgage Corporation, and Federal National Mortgage Association.
 
Some obligations issued or guaranteed by U.S. government agencies and instrumentalities are supported by the 
full faith and credit of the U.S. Treasury. Others, such as those issued by the Federal National Mortgage 
Association, are supported by discretionary authority of the U.S. government to purchase certain obligations of the 
agency or instrumentality. Still others, such as those issued by the Student Loan Marketing Association, are 
supported only by the credit of the agency or instrumentality. 

·      Bank Obligations - Certificates of deposit, time deposits and bankers' acceptances of U.S. commercial banks having total assets of at least one billion dollars and overseas branches of U.S. commercial banks and foreign banks, which in the opinion of the Sub-Advisor, are of comparable quality. However, each such bank with its branches has total assets of at least five billion dollars, and certificates, including time deposits of domestic savings and loan associations having at least one billion dollars in assets that are insured by the Federal Savings and Loan Insurance Corporation. The Fund may acquire obligations of U.S. banks that are not members of the Federal Reserve System or of the Federal Deposit Insurance Corporation.
 
  Obligations of foreign banks and obligations of overseas branches of U.S. banks are subject to somewhat different regulations and risks than those of U.S. domestic banks. For example, an issuing bank may be able to maintain that the liability for an investment is solely that of the overseas branch which could expose a Fund to a greater risk of loss. In addition, obligations of foreign banks or of overseas branches of U.S. banks may be affected by governmental action in the country of domicile of the branch or parent bank. Examples of adverse foreign governmental actions include the imposition of currency controls, the imposition of withholding taxes on interest income payable on such obligations, interest limitations, seizure or nationalization of assets, or the declaration of a moratorium. Deposits in foreign banks or foreign branches of U.S. banks are not covered by the Federal Deposit Insurance Corporation. A Fund only buys short-term instruments where the risks of adverse governmental action are believed by the Sub-Advisor to be minimal. A Fund considers these factors, along with other appropriate factors, in making an investment decision to acquire such obligations. It only acquires those which, in the opinion of management, are of an investment quality comparable to other debt securities bought by the Fund. A Fund may invest in certificates of deposit of selected banks having less than one billion dollars of assets providing the certificates do not exceed the level of insurance (currently $100,000) provided by the applicable government agency.
 
  A certificate of deposit is issued against funds deposited in a bank or savings and loan association for a definite period of time, at a specified rate of return. Normally they are negotiable. However, a Fund occasionally may invest in certificates of deposit which are not negotiable. Such certificates may provide for interest penalties in the event of withdrawal prior to their maturity. A bankers' acceptance is a short-term credit instrument issued by corporations to finance the import, export, transfer, or storage of goods. They are termed "accepted" when a bank guarantees their payment at maturity and reflect the obligation of both the bank and drawer to pay the face amount of the instrument at maturity.
 
·      Commercial Paper - Short-term promissory notes issued by U.S. or foreign corporations.
 
·      Short-term Corporate Debt - Corporate notes, bonds, and debentures that at the time of purchase have 397 days or less remaining to maturity.
 
·      Repurchase Agreements - Instruments under which securities are purchased from a bank or securities dealer with an agreement by the seller to repurchase the securities at the same price plus interest at a specified rate.
 
·      Taxable Municipal Obligations - Short-term obligations issued or guaranteed by state and municipal issuers which generate taxable income.

The ratings of nationally recognized statistical rating organization ("NRSRO"), such as Moody's Investor Services, Inc. ("Moody's") and Standard & Poor's ("S&P"), which are described in Appendix A, represent their opinions as to the quality of the money market instruments which they undertake to rate. It should be emphasized, however, that ratings

26  DESCRIPTION OF THE FUNDS’ INVESTMENTS AND RISKS  Principal Funds, Inc. 
    1-800-222-5852 


are general and are not absolute standards of quality. These ratings, including ratings of NRSROs other than Moody's and S&P, are the initial criteria for selection of portfolio investments, but the Sub-Advisor further evaluates these securities.

Municipal Obligations

The California Municipal and Tax-Exempt Bond Funds (the "Municipal Funds") can invest in "Municipal Obligations." Municipal Obligations are obligations issued by or on behalf of states, territories, and possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities, including municipal utilities, or multi-state agencies or authorities. The interest on Municipal Obligations is exempt from federal income tax in the opinion of bond counsel to the issuer. Three major classifications of Municipal Obligations are: Municipal Bonds, that generally have a maturity at the time of issue of one year or more; Municipal Notes, that generally have a maturity at the time of issue of six months to three years; and Municipal Commercial Paper, that generally has a maturity at the time of issue of 30 to 270 days.

The term "Municipal Obligations" includes debt obligations issued to obtain funds for various public purposes, including the construction of a wide range of public facilities such as airports, bridges, highways, housing, hospitals, mass transportation, schools, streets, water and sewer works, and electric utilities. Other public purposes for which Municipal Obligations are issued include refunding outstanding obligations, obtaining funds for general operating expenses, and lending such funds to other public institutions and facilities.

AMT-Subject Bonds. Industrial development bonds are issued by or on behalf of public authorities to obtain funds to provide for the construction, equipment, repair or improvement of privately operated housing facilities, sports facilities, convention or trade show facilities, airport, mass transit, industrial, port or parking facilities, air or water pollution control facilities, and certain local facilities for water supply, gas, electricity, or sewage or solid waste disposal. They are considered to be Municipal Obligations if the interest paid thereon qualifies as exempt from federal income tax in the opinion of bond counsel to the issuer, even though the interest may be subject to the federal alternative minimum tax.

·      Municipal Bonds. Municipal Bonds may be either "general obligation" or "revenue" issues. General obligation bonds are secured by the issuer's pledge of its faith, credit, and taxing power for the payment of principal and interest. Revenue bonds are payable from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source (e.g., the user of the facilities being financed), but not from the general taxing power. Industrial development bonds and pollution control bonds in most cases are revenue bonds and generally do not carry the pledge of the credit of the issuing municipality. The payment of the principal and interest on industrial revenue bonds depends solely on the ability of the user of the facilities financed by the bonds to meet its financial obligations and the pledge, if any, of real and personal property so financed as security for such payment. The Fund may also invest in "moral obligation" bonds that are normally issued by special purpose public authorities. If an issuer of moral obligation bonds is unable to meet its obligations, the repayment of the bonds becomes a moral commitment but not a legal obligation of the state or municipality in question.
 
·      Municipal Notes. Municipal Notes usually are general obligations of the issuer and are sold in anticipation of a bond sale, collection of taxes, or receipt of other revenues. Payment of these notes is primarily dependent upon the issuer's receipt of the anticipated revenues. Other notes include "Construction Loan Notes" issued to provide construction financing for specific projects, and "Bank Notes" issued by local governmental bodies and agencies to commercial banks as evidence of borrowings. Some notes ("Project Notes") are issued by local agencies under a program administered by the U.S. Department of Housing and Urban Development. Project Notes are secured by the full faith and credit of the United States.
 
  ·      Bond Anticipation Notes ("BANs") are usually general obligations of state and local governmental issuers which are sold to obtain interim financing for projects that will eventually be funded through the sale of long-term debt obligations or bonds. The ability of an issuer to meet its obligations on its BANs is primarily dependent on the issuer's access to the long-term municipal bond market and the likelihood that the proceeds of such bond sales will be used to pay the principal and interest on the BANs.
 
Principal Funds, Inc.  DESCRIPTION OF THE FUNDS’ INVESTMENTS AND RISKS  27 
www.principal.com     


·      Tax Anticipation Notes ("TANs") are issued by state and local governments to finance the current operations of such governments. Repayment is generally to be derived from specific future tax revenues. TANs are usually general obligations of the issuer. A weakness in an issuer's capacity to raise taxes due to, among other things, a decline in its tax base or a rise in delinquencies, could adversely affect the issuer's ability to meet its obligations on outstanding TANs.
 
·      Revenue Anticipation Notes ("RANs") are issued by governments or governmental bodies with the expectation that future revenues from a designated source will be used to repay the notes. In general they also constitute general obligations of the issuer. A decline in the receipt of projected revenues, such as anticipated revenues from another level of government, could adversely affect an issuer's ability to meet its obligations on outstanding RANs. In addition, the possibility that the revenues would, when received, be used to meet other obligations could affect the ability of the issuer to pay the principal and interest on RANs.
 
·      Construction Loan Notes are issued to provide construction financing for specific projects. Permanent financing, the proceeds of which are applied to the payment of construction loan notes, is sometimes provided by a commitment by the Government National Mortgage Association ("GNMA") to purchase the loan, accompanied by a commitment by the Federal Housing Administration to insure mortgage advances thereunder. In other instances, permanent financing is provided by commitments of banks to purchase the loan. The Tax-Exempt Bond and California Municipal Funds will only purchase construction loan notes that are subject to GNMA or bank purchase commitments.
 
·      Bank Notes are notes issued by local governmental bodies and agencies such as those described above to commercial banks as evidence of borrowings. The purposes for which the notes are issued are varied but they are frequently issued to meet short-term working-capital or capital-project needs. These notes may have risks similar to the risks associated with TANs and RANs.
 
·      Municipal Commercial Paper. Municipal Commercial Paper refers to short-term obligations of municipalities that may be issued at a discount and may be referred to as Short-Term Discount Notes. Municipal Commercial Paper is likely to be used to meet seasonal working capital needs of a municipality or interim construction financing. Generally they are repaid from general revenues of the municipality or refinanced with long-term debt. In most cases Municipal Commercial Paper is backed by letters of credit, lending agreements, note repurchase agreements or other credit facility agreements offered by banks or other institutions.
 
·      Variable and Floating Rate Obligations. Certain Municipal Obligations, obligations issued or guaranteed by the U.S. Government or its agencies or instrumentalities, and debt instruments issued by domestic banks or corporations may carry variable or floating rates of interest. Such instruments bear interest at rates which are not fixed, but which vary with changes in specified market rates or indices, such as a bank prime rate or tax- exempt money market index. Variable rate notes are adjusted to current interest rate levels at certain specified times, such as every 30 days. A floating rate note adjusts automatically whenever there is a change in its base interest rate adjustor, e.g., a change in the prime lending rate or specified interest rate indices. Typically such instruments carry demand features permitting the Fund to redeem at par.
 
  The Fund's right to obtain payment at par on a demand instrument upon demand could be affected by events occurring between the date the Fund elects to redeem the instrument and the date redemption proceeds are due which affects the ability of the issuer to pay the instrument at par value. The Sub-Advisor monitors on an ongoing basis the pricing, quality, and liquidity of such instruments and similarly monitors the ability of an issuer of a demand instrument, including those supported by bank letters of credit or guarantees, to pay principal and interest on demand. Although the ultimate maturity of such variable rate obligations may exceed one year, the Fund treats the maturity of each variable rate demand obligation as the longer of a) the notice period required before the Fund is entitled to payment of the principal amount through demand or b) the period remaining until the next interest rate adjustment. Floating rate instruments with demand features are deemed to have a maturity equal to the period remaining until the principal amount can be recovered through demand.
 
  The Fund may purchase participation interests in variable rate Municipal Obligations (such as industrial development bonds). A participation interest gives the purchaser an undivided interest in the Municipal
 
28  DESCRIPTION OF THE FUNDS’ INVESTMENTS AND RISKS  Principal Funds, Inc. 
    1-800-222-5852 


  Obligation in the proportion that its participation interest bears to the total principal amount of the Municipal Obligation. The Fund has the right to demand payment on seven days' notice, for all or any part of the Fund's participation interest in the Municipal Obligation, plus accrued interest. Each participation interest is backed by an irrevocable letter of credit or guarantee of a bank. Banks will retain a service and letter of credit fee and a fee for issuing repurchase commitments in an amount equal to the excess of the interest paid on the Municipal Obligations over the negotiated yield at which the instruments were purchased by the Fund.
 
·      Stand-By Commitments. The Municipal Funds may acquire stand-by commitments with respect to municipal obligations held in their respective portfolios. Under a stand-by commitment, a broker-dealer, dealer, or bank would agree to purchase, at the relevant Funds' option, a specified municipal security at a specified price. Thus, a stand-by commitment may be viewed as the equivalent of a put option acquired by a Fund with respect to a particular municipal security held in the Fund's portfolio.
 
  The amount payable to a Fund upon its exercise of a stand-by commitment normally would be 1) the acquisition cost of the municipal security (excluding any accrued interest that the Fund paid on the acquisition), less any amortized market premium or plus any amortized market or original issue discount during the period the Fund owned the security, plus, 2) all interest accrued on the security since the last interest payment date during the period the security was owned by the Fund. Absent unusual circumstances, the Fund would value the underlying municipal security at amortized cost. As a result, the amount payable by the broker-dealer, dealer or bank during the time a stand-by commitment is exercisable would be substantially the same as the value of the underlying municipal obligation.
 
  A Fund's right to exercise a stand-by commitment would be unconditional and unqualified. Although a Fund could not transfer a stand-by commitment, it could sell the underlying municipal security to a third party at any time. It is expected that stand-by commitments generally will be available to the Funds without the payment of any direct or indirect consideration. The Funds may, however, pay for stand-by commitments if such action is deemed necessary. In any event, the total amount paid for outstanding stand-by commitments held in a Fund's portfolio would not exceed 0.50% of the value of a Fund's total assets calculated immediately after each stand- by commitment is acquired.
 
  The Funds intend to enter into stand-by commitments only with broker-dealers, dealers, or banks that their Sub- Advisors believe present minimum credit risks. A Fund's ability to exercise a stand-by commitment will depend upon the ability of the issuing institution to pay for the underlying securities at the time the stand-by commitment is exercised. The credit of each institution issuing a stand-by commitment to a Fund will be evaluated on an ongoing basis by the Sub-Advisor.
 
  A Fund intends to acquire stand-by commitments solely to facilitate portfolio liquidity and does not intend to exercise its right thereunder for trading purposes. The acquisition of a stand-by commitment would not affect the valuation of the underlying municipal security. Each stand-by commitment will be valued at zero in determining net asset value. Should a Fund pay directly or indirectly for a stand-by commitment, its costs will be reflected in realized gain or loss when the commitment is exercised or expires. The maturity of a municipal security purchased by a Fund will not be considered shortened by any stand-by commitment to which the obligation is subject. Thus, stand-by commitments will not affect the dollar-weighted average maturity of a Fund's portfolio.
 
·      Other Municipal Obligations. Other kinds of Municipal Obligations are occasionally available in the marketplace, and the Fund may invest in such other kinds of obligations to the extent consistent with its investment objective and limitations. Such obligations may be issued for different purposes and with different security than those mentioned above.
 
·      Risks. of Municipal Obligations. The yields on Municipal Obligations are dependent on a variety of factors, including general economic and monetary conditions, money market factors, conditions in the Municipal Obligations market, size of a particular offering, maturity of the obligation, and rating of the issue. The Fund's ability to achieve its investment objective also depends on the continuing ability of the issuers of the Municipal Obligations in which it invests to meet their obligation for the payment of interest and principal when due.
 
Principal Funds, Inc.  DESCRIPTION OF THE FUNDS’ INVESTMENTS AND RISKS  29 
www.principal.com     


Municipal Obligations are subject to the provisions of bankruptcy, insolvency, and other laws affecting the rights and remedies of creditors, such as the Federal Bankruptcy Act. They are also subject to federal or state laws, if any, which extend the time for payment of principal or interest, or both, or impose other constraints upon enforcement of such obligations or upon municipalities to levy taxes. The power or ability of issuers to pay, when due, principal of and interest on Municipal Obligations may also be materially affected by the results of litigation or other conditions.

From time to time, proposals have been introduced before Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on Municipal Obligations. It may be expected that similar proposals will be introduced in the future. If such a proposal was enacted, the ability of the Fund to pay "exempt interest" dividends may be adversely affected. The Fund would reevaluate its investment objective and policies and consider changes in its structure.

Special Considerations Relating to California Municipal Obligations

The California Municipal Fund concentrates its investments in California municipal obligations, and therefore may be significantly impacted by political, economic, or regulatory developments that affect issuers in California and their ability to pay principal and interest on their obligations. The ability of issuers to pay interest on, and repay principal of, California municipal obligations may be affected by 1) amendments to the California Constitution and related statutes that limit the taxing and spending authority of California government entities, 2) voter initiatives, 3) a wide variety of California laws and regulations, including laws related to the operation of health care institutions and laws related to secured interests in real property, and 4) the general financial condition of the State of California and the California economy.

Insurance

The insured municipal obligations in which the Municipal Funds may invest are insured under insurance policies that relate to the specific municipal obligation in question and that are issued by an insurer having a claims-paying ability rated AAA by S&P or Aaa by Moody's. This insurance is generally non-cancelable and will continue in force so long as the municipal obligations are outstanding and the insurer remains in business.

The insured municipal obligations are generally insured as to the scheduled payment of all installments of principal and interest as they fall due. The insurance covers only credit risk and therefore does not guarantee the market value of the obligations in a Fund's investment portfolio or a Fund's NAV. The Fund's NAV will continue to fluctuate in response to fluctuations in interest rates. A Fund's investment policy requiring investment in insured municipal obligations will not affect the Fund's ability to hold its assets in cash or to invest in escrow-secured and defeased bonds or in certain short-term tax-exempt obligations, or affect its ability to invest in uninsured taxable obligations for temporary or liquidity purposes or on a defensive basis.

Taxable Investments of the Municipal Funds

Each of the Municipal Funds may invest a portion of its assets, as described in the prospectus, in taxable short-term investments consisting of: Obligations issued or guaranteed by the U.S. Government or its agencies or instrumentalities, domestic bank certificates of deposit and bankers' acceptances, short-term corporate debt securities such as commercial paper, and repurchase agreements ("Taxable Investments"). These investments must have a stated maturity of one year or less at the time of purchase and must meet the following standards: banks must have assets of at least $1 billion; commercial paper must be rated at least "A" by S&P or "Prime" by Moody's or, if not rated, must be issued by companies having an outstanding debt issue rated at least "A" by S&P or Moody's; corporate bonds and debentures must be rated at least "A" by S&P or Moody's. Interest earned from Taxable Investments is taxable to investors. When, in the opinion of the Fund's Manager, it is advisable to maintain a temporary "defensive" posture, each Municipal Fund may invest without limitation in Taxable Investments. At other times, Taxable Investments, Municipal Obligations that do not meet the quality standards required for the 80% portion of the portfolio and Municipal Obligations the interest on which is treated as a tax preference item for purposes of the federal alternative minimum tax will not exceed 20% of the Fund's total assets.

Other Investment Companies

Each Fund reserves the right to invest up to 10% of its total assets in the securities of all investment companies, but may not acquire more than 3% of the voting securities of, nor invest more than 5% of its total assets in securities of,

30  DESCRIPTION OF THE FUNDS’ INVESTMENTS AND RISKS  Principal Funds, Inc. 
    1-800-222-5852 


any other investment company. Securities of other investment companies, including shares of closed-end investment companies, unit investment trusts, various exchange-traded funds ("ETFs"), and other open-end investment companies, represent interests in professionally managed portfolios that may invest in any type of instrument. Certain types of investment companies, such as closed-end investment companies, issue a fixed number of shares that trade on a stock exchange or over-the-counter at a premium or a discount to their net asset value. Others are continuously offered at net asset value, but may also be traded in the secondary market. ETFs are often structured to perform in a similar fashion to a broad-based securities index. Investing in ETFs involves substantially the same risks as investing directly in the underlying instruments. In addition, ETFs involve the risk that they will not perform in exactly the same fashion, or in response to the same factors, as the index or underlying instruments.

As a shareholder in an investment company, a Fund would bear its ratable share of that entity's expenses, including its advisory and administrative fees. The Fund would also continue to pay its own advisory fees and other expenses. Consequently, the Fund and its shareholders, in effect, will be absorbing two levels of fees with respect to investments in other investment companies.

Industry Concentrations

Each of the Principal LifeTime Funds and Strategic Asset Management Portfolios concentrates its investments in shares of other Principal mutual funds.

Each of the other Funds, except the Global Diversified Income, Global Real Estate Securities, Preferred Securities, and Real Estate Securities Funds, may not concentrate (invest more than 25% of its assets) its investments in any particular industry. The LargeCap S&P 500 Index, MidCap S&P 400 Index, and SmallCap S&P 600 Index Funds may concentrate their investments in a particular industry only to the extent that the relevant indices are so concentrated. The International Growth Fund, LargeCap Growth Fund I, LargeCap Growth Fund II, LargeCap Value Fund I, LargeCap Value Fund II, MidCap Growth Fund II, SmallCap Growth Fund II, SmallCap Value Fund II and each of the funds sub-advised by Edge Asset Management, Inc. use the industry groups of Global Industry Classification Standard (GICS®). The other Funds use industry classifications based on the "Directory of Companies Filing Annual Reports with the Securities and Exchange Commission ("SEC")." The Funds interpret their policy with respect to concentration in a particular industry to apply to direct investments in the securities of issuers in a particular industry. For purposes of this restriction, mortgage-backed securities that are issued or guaranteed by the U.S. government, its agencies or instrumentalities are not subject to the Funds' industry concentration restrictions, by virtue of the exclusion from that test available to all U.S. government securities. In the case of privately issued mortgage-related securities, or any asset-backed securities, and municipal obligations issued by government or political subdivisions of governments, the Funds take the position that such securities do not represent interests in any particular "industry" or group of industries.

Portfolio Turnover

Portfolio turnover is a measure of how frequently a portfolio's securities are bought and sold. The portfolio turnover rate is generally calculated as the dollar value of the lesser of a portfolio's purchases or sales of shares of securities during a given year, divided by the monthly average value of the portfolio securities during that year (excluding securities whose maturity or expiration at the time of acquisition were less than one year). For example, a portfolio reporting a 100% portfolio turnover rate would have purchased and sold securities worth as much as the monthly average value of its portfolio securities during the year.

It is not possible to predict future turnover rates with accuracy. Many variable factors are outside the control of a portfolio manager. The investment outlook for the securities in which a portfolio may invest may change as a result of unexpected developments in securities markets, economic or monetary policies, or political relationships. High market volatility may result in a portfolio manager using a more active trading strategy than might otherwise be employed. Each portfolio manager considers the economic effects of portfolio turnover but generally does not treat the portfolio turnover rate as a limiting factor in making investment decisions.

Sale of shares by investors may require the liquidation of portfolio securities to meet cash flow needs. In addition, changes in a particular portfolio's holdings may be made whenever the portfolio manager considers that a security is no longer appropriate for the portfolio or that another security represents a relatively greater opportunity. Such changes may be made without regard to the length of time that a security has been held.

Principal Funds, Inc.  DESCRIPTION OF THE FUNDS’ INVESTMENTS AND RISKS  31

Higher portfolio turnover rates generally increase transaction costs that are expenses of the Account. Active trading may generate short-term gains (losses) for taxable shareholders.

The following Funds had significant variation in portfolio turnover rates over the two most recently completed fiscal years:

·      California Municipal Fund (2007 - 63.7%; 2006 - 29.0%): In 2007, the Fund experienced increased turnover due to redemptions.
·      Real Estate Securities Fund (2007 - 77.8%; 2006 - 37.8%): Market conditions changed dramatically in 2007 with real estate stock prices under pressure after several consecutive years of strong performance. The changed environment dictated an above average amount of portfolio repositioning.
·      Tax Exempt Bond Fund (2007 - 51.0%; 2006 - 25.0%): Redemptions were greater in 2007 than in 2006. As interest rates rallied the sub-advisor attempted to bring the portfolio's duration back in line with the index. Given the volatile market environment, this strategy did increase turnover as the sub-advisor bought and sold securities to try and remain neutral in the duration posture. The volatility of the market also produced opportunities to improve the fund's positioning with respect to yield, which resulted in increased turnover.

MANAGEMENT

Board of Directors

Under Maryland law, the Board of Directors of the Fund is responsible for overseeing the management of the Fund's business and affairs. The Board meets several times during the year to fulfill this responsibility. Other than serving as Directors, most of the Board members have no affiliation with the Fund or its service providers. Each Director serves until a successor is duly qualified and elected.

Management Information

The following table presents certain information regarding the Directors of the Fund, including their principal occupations which, unless specific dates are shown, are of more than five years duration. In addition, the table includes information concerning other directorships held by each Director in reporting companies under the Securities Exchange Act of 1934 or registered investment companies under the 1940 Act. Information is listed separately for those Directors who are "interested persons" (as defined in the 1940 Act) of the Fund (the "Interested Directors") and those Directors who are not interested persons of the Fund (the "Independent Directors"). All Directors serve as directors for each of the two investment companies (with a total of 114 portfolios) sponsored by Principal Life Insurance Company (“Principal Life”): the Fund and the Principal Variable Contracts Funds, Inc. (collectively, the "Fund Complex").

Each officer of the Fund has the same position with the Principal Variable Contracts Funds, Inc.

Board Committees. Effective December 2007, the Fund Complex's board has the following four committees: Audit Committee, Executive Committee, Nominating and Governance Committee, and Operations Committee(1). Committee membership is identified on the previous pages. Each committee must report its activities to the Board on a regular basis.

Audit Committee

The primary purpose of the Committee is to assist the Board in fulfilling certain of its responsibilities. The Audit Committee serves as an independent and objective party to monitor the Fund Complex's accounting policies, financial reporting and internal control system, as well as the work of the independent registered public accountants. The Audit Committee assists Board oversight of 1) the integrity of the Fund Complex's financial statements; 2) the Fund Complex's compliance with certain legal and regulatory requirements; 3) the independent registered public accountants' qualifications and independence; and 4) the performance of the Fund Complex's independent registered public accountants. The Audit Committee also serves to provide an open avenue of communication among the independent registered public accountants, the Manager's internal auditors, Fund Complex management, and the Board.

Executive Committee

The Committee's primary purpose is to exercise certain powers of the Board of Directors when the Board is not in session. When the Board is not in session, the Committee may exercise all powers of the Board in the management of the business of the Fund Complex except the power to 1) authorize dividends or distributions on stock; 2) issue stock, except as permitted by law 3) recommend to the stockholders any action which requires stockholder approval; 4) amend the bylaws; or 5) approve any merger or share exchange which does not require stockholder approval.

Nominating and Governance Committee

The Committee's primary purpose is to oversee 1) the structure and efficiency of the Boards of Directors and the committees the Boards establish, and 2) the activities of the Fund Complex's Chief Compliance Officer. The Committee responsibilities include evaluating board membership and functions, committee membership and functions, insurance coverage, and legal and compliance matters.

The nominating functions of the Nominating and Governance Committee include selecting and nominating all candidates who are not "interested persons" of the Fund Complex (as defined in the 1940 Act) for election to the Board. Generally, the committee requests director nominee suggestions from the committee members and management. In addition, the committee will consider director candidates recommended by shareholders of the Fund Complex. Recommendations should be submitted in writing to Principal Funds, Inc. at 680 8th Street, Des Moines, Iowa 50392. The committee has not established any specific minimum qualifications for nominees. When evaluating a person as a potential nominee to serve as an independent director, the committee will generally consider, among other factors: age; education; relevant business experience; geographical factors; whether the person is "independent" and otherwise qualified under applicable laws and regulations to serve as a director; and whether the person is willing to serve, and willing and able to commit the time necessary for attendance at meetings and the performance of the duties of an independent director. The committee also meets personally with the nominees and conducts a reference check. The final decision is based on a combination of factors, including the strengths and the experience an individual may bring to the Board. The Board does not use regularly the services of any professional search firms to identify or evaluate or assist in identifying or evaluating potential candidates or nominees.

Operations Committee

The Committee's primary purpose is to oversee the provision of administrative and distribution services to the Fund Complex, communications with the Fund Complex's shareholders, and review and oversight of the Fund Complex's operations.

(1)   The Fund Complex's board previously had two committees: an Audit and Nominating Committee and an Executive 
       Committee. The Audit and Nominating Committee was comprised of all the Independent Directors. During the last 
       fiscal year, the Audit and Nominating Committee met four times. The Executive Committee membership was 
       comprised of Barbara Lukavsky, Ralph Eucher, and Larry Zimpleman. During the last fiscal year, the Executive 
       Committee did not meet.

The following tables set forth the aggregate dollar range of the equity securities of the mutual funds within the Fund Complex which were beneficially owned by the Directors as of December 31, 2007. The Fund Complex currently includes the separate series of the Fund and of Principal Variable Contracts Funds, Inc.

For the purpose of these tables, beneficial ownership means a direct or indirect pecuniary interest.

Directors who beneficially owned shares of the series of the Fund did so through variable life insurance and variable annuity contracts. Please note that exact dollar amounts of securities held are not listed. Rather, ownership is listed based on the following dollar ranges:

Compensation. The Fund does not pay any remuneration to its Directors who are employed by the Manager or its affiliates or to its officers who are furnished to the Fund by the Manager and its affiliates pursuant to the Management Agreement. Each Director who is not an "interested person" received compensation for service as a member of the Boards of all investment companies sponsored by Principal Life based on a schedule that takes into account an annual retainer amount, the number of meetings attended, and expenses incurred. Director compensation and related expenses are allocated to each of the Funds based on the net assets of each relative to combined net assets of all of the investment companies sponsored by Principal Life.

The following table provides information regarding the compensation received by the Independent Directors from the Fund and from the Fund Complex during the fiscal year ended October 31, 2007. On that date, there were 2 funds (with a total of 108 portfolios in the Fund Complex). The Fund does not provide retirement benefits to any of the Directors.

The Directors and Officers of the Fund, member companies of the Principal Financial Group, and certain other persons may purchase shares of the Funds without the payment of any sales charge. The sales charge is waived on these transactions because there are either no distribution costs or only minimal distribution costs associated with the transactions. For a description of the persons entitled to a waiver of sales charge in connection with their purchase of shares of the Funds, see the discussion of the waiver of sales charges under the caption "Choosing a Share Class" in the prospectus for the Class A, B, and C shares.

The Principal LifeTime Funds, SAM Portfolios, or Principal Life Insurance Company will vote in the same proportion as shares of the Funds owned by other shareholders. Therefore, neither the Principal LifeTime Funds, SAM Portfolios nor Principal Life Insurance Company exercise voting discretion.

The By-laws of the Fund sets the quorum requirement (a quorum must be present at a meeting of shareholders for business to be transacted). The By-laws of the Fund states that a quorum is "The presence in person or by proxy of one-third of the shares of each Fund outstanding at the close of business on the Record Date constitutes a quorum for a meeting of that Fund."

Certain proposals presented to shareholders for approval require the vote of a "majority of the outstanding voting securities," which is a term defined in the 1940 Act to mean, with respect to a Fund, the affirmative vote of the lesser of 1) 67% or more of the voting securities of the Fund present at the meeting of that Fund, if the holders of more than 50% of the outstanding voting securities of the Fund are present in person or by proxy, or 2) more than 50% of the outstanding voting securities of the Fund (a "Majority of the Outstanding Voting Securities").

Certain proposals require for approval the affirmative vote of the holders of a plurality of the shares voted at the meeting and thus may be approved by vote of a Principal LifeTime Fund.

The Fund is unaware of any persons who own beneficially more than 5% of the Fund's outstanding shares.

The Sub-Sub-Advisors

PGI has entered into a sub-sub-advisory agreement with Spectrum for the Bond & Mortgage Securities and High Quality Intermediate-Term Bond Funds. Under the agreement, the sub-sub-advisor agrees to manage the day-to-day investment of the Funds' assets allocated to it consistent with the Funds' investment objectives, policies and restrictions and will be responsible for, among other things, placing all orders for the purchase and sale of portfolio securities, subject to supervision and monitoring by the Sub-Advisor and oversight by the Board. Each firm, at its own expense, will provide all investment, management, and administrative personnel, facilities, and equipment necessary for the investment advisory services which it conducts for the Funds.

Under the agreement, PGI pays the sub-sub-advisor a fee which is accrued daily and paid monthly (calculated as percentage of the average daily net assets managed by the firm). Entering into these agreements does not change the management fee that the Fund pays Principal under its Management Agreement or the sub-advisory fee that Principal pays PGI under its sub-advisory agreement. PGI, and not the Fund, will bear the expenses of the services that each of the sub-sub-advisors provides to the Fund under the agreements.

These Codes are designed to prevent persons with access to information regarding the portfolio trading activity of a Fund from using that information for their personal benefit. In certain circumstances, personal securities trading is permitted in accordance with procedures established by the Codes. The Boards of Directors of Principal, the Fund, PFD, Princor and each of the Sub-Advisors periodically review their respective Codes. The Codes are on file with, and available from, the Securities and Exchange Commission. A copy of the Fund's Code will also be provided upon request, which may be made by contacting the Fund.

Each Fund pays all of its operating expenses, except those Funds for which Principal has agreed to pay such expenses. Under the terms of the Management Agreement, Principal is responsible for paying the expenses associated with the organization of each Fund, including the expenses incurred in the initial registration of the Funds with the Securities and Exchange Commission, compensation of personnel, officers and directors who are also affiliated with Principal, and expenses and compensation associated with furnishing office space and all necessary office facilities and equipment and personnel necessary to perform the general corporate functions of the Fund. Portfolio accounting services are provided to each Fund at cost, under the terms of the Management Agreement. Principal Shareholder Services, Inc., a wholly owned subsidiary of Principal, provides transfer agent services for Class A, B, C, J, S, R-1, R-2, R-3, R-4, R-5, and Institutional Class shares, including qualifying shares of the Fund for sale in states and other jurisdictions, for each Fund pursuant to an additional agreement with the Fund. Principal is also responsible for providing certain shareholder services to the R-1, R-2, R-3, R-4 and R-5 share classes pursuant to an additional agreement.

The Manager has contractually agreed to limit the Fund's expenses (excluding interest the Funds incur in connection with investments they make) on certain share classes of certain of the Funds. The reductions and reimbursements are in amounts that maintain total operating expenses at or below certain limits. The limits are expressed as a percentage of average daily net assets attributable to each respective class on an annualized basis.

       securities (except money market separate accounts),

In calculating the fee for each Fund, each Sub-Advisor, except J.P. Morgan, Lehman Brothers and MacKay Shields, has agreed that, assets of any existing registered investment company sponsored by Principal Life Insurance Company to which the Sub-Advisor provides investment advisory services and which have the same investment mandate as the Fund for which the fee is being calculated, will be combined (together, the "Aggregated Assets"). The fee charged for the assets in a Fund shall be determined by calculating a fee on the value of the Aggregated Assets using the fee schedules described in the tables below and multiplying the aggregate fee by a fraction, the numerator of which is the amount of assets in the Fund and the denominator of which is the amount of the Aggregated Assets.

Class A shares are generally sold with a sales charge that is a variable percentage based on the amount of the purchase, as described in the prospectus. Certain redemptions of Class A shares within 18 months of purchase may be subject to a contingent deferred sales charge ("CDSC"), as described in the prospectus. Participants in employer-sponsored plans that had at least $1 million in assets as of January 12, 2007 can purchase Class A shares at net asset value provided the participant notes that he or she meets this qualification on the application to purchase shares.

Class B shares are not subject to a sales charge at the time of purchase but are subject to a CDSC on shares redeemed within five full years of purchase, as described in the prospectus.

The Class B share CDSC on shares purchased on or before January 12, 2007, if any, is determined by multiplying the lesser of the market value at the time of redemption or the initial purchase price of the shares sold by the appropriate percentage from the table below (for shares issued in connection with the WM Reorganization, the CDSC is determined by multiplying the initial purchase price by the appropriate percentage):

    Accounts Included in 
    Certain Sponsored Plans 
Years Since Purchase  CDSC as a % of  Established After 02/01/1998 
Payments Made  Dollar Amount  and Before 03/01/2002 
2 years or less           4.00%                        3.00%
more than 2 years, up to 4 years           3.00 2.00
more than 4 years, up to 5 years           2.00 1.00
more than 5 years, up to 6 years           1.00 None
more than 6 years           None None

Class C shares are not subject to a sales charge at the time of purchase but are subject to a 1% CDSC on shares redeemed within 12 months of purchase, as described in the prospectus.

The Class J shares are sold without any front-end sales charge. A CDSC of 1% is imposed if Class J shares are redeemed within 18 months of purchase, as described in the prospectus.

Contingent deferred sales charges for Class A, B, C, and J shares are waived on shares:

·      that were purchased pursuant to the Small Amount Force Out ("SAFO") program;
·      shares redeemed within 90 days after an account is re-registered due to a shareholder's death;
·      shares redeemed due to the shareholder's post-purchase disability, as defined in the Internal Revenue Code of 1986, as amended;
·      shares redeemed from retirement plans to satisfy minimum distribution rules under the Internal Revenue Code;
·      shares redeemed to pay retirement plan fees;
·      shares redeemed involuntarily from small balance accounts (values of less than $300);

·      shares redeemed from a retirement plan to assure the plan complies with Sections 401(k), 401(m), 408(k) and 415 of the Internal Revenue Code; or
·      shares redeemed from retirement plans qualified under Section 401(a) of the Internal Revenue Code due to the plan participant's death, disability, retirement, or separation from service after attaining age 55.

Class S shares are available without any front-end sales charge or contingent deferred sales charge.

The R-1, R-2, R-3, R-4, R-5, and Institutional Classes are available without any front-end sales charge or contingent deferred sales charge. The R-1, R-2, R-3, R-4, and R-5 Classes are available through employer-sponsored retirement plans. Such plans may impose fees in addition to those charged by the Funds. The R-1, R-2, R-3, R-4, and R-5 share classes are subject to asset based charges (described below).

The service fees are calculated and accrued daily and paid monthly to Principal (or at such other intervals as the Fund and Principal may agree).

Administrative Service Agreement (R-1, R-2, R-3, R-4, and R-5 Classes only)

However, the appointment of an agent shall not relieve Principal of any of its responsibilities or liabilities under those Agreements. Any fees paid to agents under these Agreements shall be the sole responsibility of Principal.

Rule 12b-1 Fees / Distribution Plans and Agreements

In addition to the management and service fees, certain of the Fund's share classes, are subject to Distribution Plans and Agreements (described below) sometimes referred to as a Rule 12b-1 Plan. Rule 12b-1 permits a fund to pay expenses associated with the distribution of its shares in accordance with a plan adopted by the Board of Directors and approved by its shareholders. Pursuant to such rule, the Board of Directors and initial shareholders of the R-1, R-2, R-3, R-4, A, B, C, J, and S Classes of shares have approved and entered into a Distribution Plan and Agreement. The Fund believes the Distribution Plan and Agreement will be beneficial as it may position the Fund to be able to build and retain assets which will, in turn, have a positive effect on total expense ratios and provide flexibility in the management of the Fund by reducing the need to liquidate portfolio securities to meet redemptions. The Fund also believes the Plan will encourage registered representatives to provide ongoing servicing to the shareholders.

In adopting the Plans, the Board of Directors (including a majority of directors who are not interested persons of the Fund (as defined in the 1940 Act), hereafter referred to as the independent directors) determined that there was a reasonable likelihood that the Plan would benefit the Funds and the shareholders of the affected classes. Pursuant to Rule 12b-1, information about revenues and expenses under the Plans is presented to the Board of Directors each quarter for its consideration in continuing the Plans. Continuance of the Plans must be approved by the Board of Directors, including a majority of the independent directors, annually. The Plans may be amended by a vote of the Board of Directors, including a majority of the independent directors, except that the Plans may not be amended to materially increase the amount spent for distribution without majority approval of the shareholders of the affected class. The Plans terminate automatically in the event of an assignment and may be terminated upon a vote of a majority of the independent directors or by vote of a majority of the outstanding voting securities of the affected class.

Payments under the 12b-1 plans will not automatically terminate for funds that are closed to new investors or to additional purchases by existing shareholders. The Fund Board will determine whether to terminate, modify or leave unchanged the 12b-1 plan at the time the board directs the implementation of the closure of the fund.

The Plans provide that each Fund makes payments to the Fund's Distributor from assets of each share class that has a Plan to compensate the Distributor and other selling dealers, various banks, broker-dealers and other financial intermediaries, for providing certain services to the Fund. Such services may include:

·      formulation and implementation of marketing and promotional activities;
·      preparation, printing, and distribution of sales literature;
·      preparation, printing, and distribution of prospectuses and the Fund reports to other than existing shareholders;
·      obtaining such information with respect to marketing and promotional activities as the Distributor deems advisable;
·      making payments to dealers and others engaged in the sale of shares or who engage in shareholder support services; and
·      providing training, marketing, and support with respect to the sale of shares.

The Fund pays the Distributor a fee after the end of each month at an annual rate as a percentage of the daily net asset value of the assets attributable to each share class as follows:



  Maximum 
  Annualized 
                                                                                                 Share Class  12b-1 Fee 
         R-1  0.35% 
         R-2  0.30% 
         R-3  0.25% 
         Class A shares (except Short-Term Bond, LargeCap S&P 500 Index, Money Market, and Ultra Short)(1)  0.25% 
         Class A shares of Short-Term Bond, LargeCap S&P 500 Index, and Ultra Short  0.15% 
         Class B shares(1)  1.00% 
         Class C shares(1)  1.00% 
         Class J shares (except Money Market and SmallCap Blend)(1)  0.45% 
         Class J shares of Money Market(1)  0.25% 
         Class J shares of SmallCap Blend  0.15% 
         R-4  0.10% 
         Class S shares of Money Market  0.35% 
 
(1) The Distributor also receives the proceeds of any CDSC imposed on the redemption of Class A, B, C, or J shares.   

The Distributor may remit on a continuous basis all of these sums (up to 0.25% for Class B shares) to its investment representatives and other financial intermediaries as a trail fee in recognition of their services and assistance.

Currently, the Distributor makes payments to dealers on accounts for which such dealer is designated dealer of record. Payments are based on the average net asset value of the accounts invested in Class A, Class B, Class C, Class J, Class S, R-1 Class, R-2 Class, R-3 Class, R-4 Class, or R-5 Class shares.

At least quarterly, the Distributor provides to the Fund's Board of Directors, and the Board reviews, a written report of the amounts expended pursuant to the Plans and the purposes for which such expenditures were made.

Under the Plans, the Funds have no legal obligation to pay any amount that exceeds the compensation limit. The Funds do not pay, directly or indirectly, interest, carrying charges, or other financing costs in association with these Plans. All fees paid under a Fund's Rule 12b-1 Plan are paid to the Distributor, which is entitled to retain such fees paid by the Fund without regard to the expenses which it incurs.

BROKERAGE ALLOCATION AND OTHER PRACTICES

Brokerage on Purchases and Sales of Securities

All orders for the purchase or sale of portfolio securities are placed on behalf of a Fund by the Fund's Sub-Advisor or Sub-Sub-Advisor pursuant to the terms of the applicable sub-advisory agreement. In distributing brokerage business

Principal Funds, Inc.  BROKERAGE ALLOCATION AND OTHER PRACTICES  99 
www.principal.com     


arising out of the placement of orders for the purchase and sale of securities for any Fund, the objective of each Fund's Sub-Advisor is to obtain the best overall terms. In pursuing this objective, a Sub-Advisor considers all matters it deems relevant, including the breadth of the market in the security, the price of the security, the financial condition and executing capability of the broker or dealer, confidentiality, including trade anonymity, and the reasonableness of the commission, if any (for the specific transaction and on a continuing basis). This may mean in some instances that a Sub-Advisor will pay a broker commissions that are in excess of the amount of commissions another broker might have charged for executing the same transaction when the Sub-Advisor believes that such commissions are reasonable in light of a) the size and difficulty of the transaction, b) the quality of the execution provided, and c) the level of commissions paid relative to commissions paid by other institutional investors. (Such factors are viewed both in terms of that particular transaction and in terms of all transactions that broker executes for accounts over which the Sub-Advisor exercises investment discretion. The Board has also adopted a policy and procedure designed to prevent the funds from compensating a broker/dealer for promoting or selling fund shares by directing brokerage transactions to that broker/dealer for the purpose of compensating the broker/dealer for promoting or selling fund shares. Therefore, the Sub-Advisor may not compensate a broker/dealer for promoting or selling fund shares by directing brokerage transactions to that broker/dealer for the purpose of compensating the broker/dealer for promoting or selling fund shares. A Sub-Advisor may purchase securities in the over-the-counter market, utilizing the services of principal market makers unless better terms can be obtained by purchases through brokers or dealers, and may purchase securities listed on the NYSE from non-Exchange members in transactions off the Exchange.)

A Sub-Advisor may give consideration in the allocation of business to services performed by a broker (e.g., the furnishing of statistical data and research generally consisting of, but not limited to, information of the following types: analyses and reports concerning issuers, industries, economic factors and trends, portfolio strategy, and performance of client accounts). If any such allocation is made, the primary criteria used will be to obtain the best overall terms for such transactions. A Sub-Advisor may also pay additional commission amounts for research services. Such statistical data and research information received from brokers or dealers as described above may be useful in varying degrees and a Sub-Advisor may use it in servicing some or all of the accounts it manages. Sub-Advisors allocated portfolio transactions for the Funds indicated in the following table to certain brokers for the year ended October 31, 2007 due to research services provided by such brokers. The table also indicates the commissions paid to such brokers as a result of these portfolio transactions.

*Information for the period 10/1/2006 through 9/30/07.   

Subject to the rules promulgated by the SEC, as well as other regulatory requirements, the Board has approved procedures whereby a Fund may purchase securities that are offered in underwritings in which an affiliate of a Sub-Advisor, or the Manager, participates. These procedures prohibit a Fund from directly or indirectly benefiting a Sub-Advisor affiliate or a Manager affiliate in connection with such underwritings. In addition, for underwritings where a Sub-Advisor affiliate or a Manager participates as a principal underwriter, certain restrictions may apply that could, among other things, limit the amount of securities that the Fund could purchase in the underwritings. The Sub-Advisor shall determine the amounts and proportions of orders allocated to the Sub-Advisor or affiliate. The Directors of the Fund will receive quarterly reports on these transactions.

The Board has approved procedures that permit a Fund to effect a purchase or sale transaction between the Fund and any other affiliated mutual fund or between the Fund and affiliated persons of the Fund under limited circumstances prescribed by SEC rules. Any such transaction must be effected without any payment other than a cash payment for the securities, for which a market quotation is readily available, at the current market price; no brokerage commission or fee (except for customary transfer fees), or other remuneration may be paid in connection with the transaction. The Board receives quarterly reports of all such transactions.

The Board has also approved procedures that permit a Fund's sub-advisor to place portfolio trades with an affiliated broker under circumstances prescribed by SEC Rules 17e-1 and 17a-10. The procedures require that total commissions, fees, or other remuneration received or to be received by an affiliated broker must be reasonable and fair compared to the commissions, fees or other remuneration received by other brokers in connection with comparable transactions involving similar securities being purchased or sold on a securities exchange during a comparable time period. The Board receives quarterly reports of all transactions completed pursuant to the Fund's procedures.

Purchases and sales of debt securities and money market instruments usually are principal transactions; portfolio securities are normally purchased directly from the issuer or from an underwriter or marketmakers for the securities. Such transactions are usually conducted on a net basis with the Fund paying no brokerage commissions. Purchases from underwriters include a commission or concession paid by the issuer to the underwriter, and the purchases from dealers serving as marketmakers include the spread between the bid and asked prices.

The Board has approved procedures whereby a Fund may participate in a commission recapture program. Commission recapture is a form of institutional discount brokerage that returns commission dollars directly to a Fund. It provides a way to gain control over the commission expenses incurred by a Fund's Manager and/or Sub-Advisor, which can be significant over time and thereby reduces expenses, improves cash flow and conserves assets. A Fund can derive commission recapture dollars from both equity trading commissions and fixed-income (commission equivalent) spreads. The Funds (except the International Fund I and the MidCap Growth Fund II) may participate in a program through a relationship with Frank Russell Securities, Inc. The International Fund I participates in the program offered by FMR and Fidelity Management Trust Company. From time to time, the Board reviews whether participation in the recapture program is in the best interest of the Funds.

The following table shows the brokerage commissions paid during the periods indicated.

(2) Period from October 1, 2007, date operations commenced, through October 31, 2007. 

The primary reasons for changes in several Funds' brokerage commissions for the three years were changes in Fund size; changes in market conditions; and changes in money managers of certain Funds, which required substantial portfolio restructurings, resulting in increased securities transactions and brokerage commissions.

Material differences, if any, between the percentage of a Fund's brokerage commissions paid to a broker and the percentage of transactions effected through that broker reflect the commissions rates the sub-advisor has negotiated with the broker. Commission rates a sub-advisor pays to brokers may vary and reflect such factors as the trading volume placed with a broker, the type of security, the market in which a security is traded and the trading volume of that security, the types of services provided by the broker (i.e. execution services only or additional research services) and the quality of a broker's execution.

Allocation of Trades by the Sub-Advisors and Sub-Sub-Advisors

Each Sub-Advisor and Sub-Sub-Advisor manages a number of accounts other than the Fund's portfolios. Each has adopted and implemented policies and procedures that it believes address the potential conflicts associated with managing accounts for multiple clients and ensures that all clients are treated fairly and equitably.

Investments the Sub-Advisor or Sub-Sub-Advisor deems appropriate for the Fund's portfolio may also be deemed appropriate by it for other accounts. Therefore, the same security may be purchased or sold at or about the same time for both the Fund's portfolio and other accounts. In such circumstances, the Sub-Advisor or Sub-Sub-Advisor may determine that orders for the purchase or sale of the same security for the Fund's portfolio and one or more other accounts should be combined. In this event the transactions will be priced and allocated in a manner deemed by the Sub-Advisor or Sub-Sub-Advisor to be equitable and in the best interests of the Fund portfolio and such other accounts. While in some instances combined orders could adversely affect the price or volume of a security, the Fund believes that its participation in such transactions on balance will produce better overall results for the Fund.

PURCHASE AND REDEMPTION OF SHARES

Purchase of Shares

Participating insurance companies and certain other designated organizations are authorized to receive purchase orders on the Funds' behalf and those organizations are authorized to designate their agents and affiliates as intermediaries to receive purchase orders. Purchase orders are deemed received by a Fund when authorized organizations, their agents or affiliates receive the order. The Funds are not responsible for the failure of any designated organization or its agents or affiliates to carry out its obligations to its customers. Class A shares of the Funds are purchased at their public offering price and other shares of the Funds are purchased at the net asset value ("NAV") per share, as determined at the close of the regular trading session of the NYSE next occurring after a purchase order is received and accepted by an authorized agent of a Fund. In order to receive a day's price, an order

126  PURCHASE AND REDEMPTION OF SHARES  Principal Funds, Inc. 
    1-800-222-5852 


must be received in good order by the close of the regular trading session of the NYSE as described below in "Pricing of Fund Shares."

Sales of Shares

Payment for shares tendered for redemption is ordinarily made in cash. The Fund may determine, however, that it would be detrimental to the remaining shareholders to make payment of a redemption order wholly or partly in cash. The Fund may, therefore, pay the redemption proceeds in whole or in part by a distribution "in kind" of securities from the Fund's portfolio in lieu of cash. If the Fund pays the redemption proceeds in kind, the redeeming shareholder might incur brokerage or other costs in selling the securities for cash. The Fund will value securities used to pay redemptions in kind using the same method the Fund uses to value its portfolio securities as described below in "Pricing of Fund Shares."

The right to require the Funds to redeem their shares may be suspended, or the date of payment may be postponed, whenever: 1) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed except for holidays and weekends; 2) the SEC permits such suspension and so orders; or 3) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable.

Certain designated organizations are authorized to receive sell orders on the Fund's behalf and those organizations are authorized to designate their agents and affiliates as intermediaries to receive redemption orders. Redemption orders are deemed received by the Fund when authorized organizations, their agents or affiliates receive the order. The Fund is not responsible for the failure of any designated organization or its agents or affiliates to carry out its obligations to its customers.

Principal Management Corporation (the "Manager") may recommend to the Board, and the Board may elect, to close certain funds to new investors or close certain funds to new and existing investors. The Manager may make such a recommendation when a fund approaches a size where additional investments in the fund have the potential to adversely impact fund performance and make it increasingly difficult to keep the fund fully invested in a manner consistent with its investment objective.

PRICING OF FUND SHARES

Each Fund's shares are bought and sold at the current net asset value ("NAV") per share. Each Fund's NAV for each class is calculated each day the New York Stock Exchange ("NYSE") is open, as of the close of business of the Exchange (normally 3:00 p.m. Central Time). The NAV of Fund shares is not determined on days the NYSE is closed (generally, New Year's Day; Martin Luther King, Jr. Day; Washington's Birthday/Presidents' Day; Good Friday; Memorial Day; Independence Day; Labor Day; Thanksgiving Day; and Christmas). When an order to buy or sell shares is received, the share price used to fill the order is the next price calculated after the order is received in proper form.

For all Funds except the Money Market Fund, the share price is calculated by:

·      taking the current market value of the total assets of the Fund
·      subtracting liabilities of the Fund
·      dividing the remainder proportionately into the classes of the Fund
·      subtracting the liability of each class
·      dividing the remainder by the total number of shares owned in that class.

In determining NAV, securities listed on an Exchange, the NASDAQ National Market and foreign markets are valued at the closing prices on such markets, or if such price is lacking for the trading period immediately preceding the time of determination, such securities are valued at their current bid price.

Municipal securities held by the Funds are traded primarily in the over-the-counter market. Valuations of such securities are furnished by one or more pricing services employed by the Funds and are based upon appraisals obtained by a pricing service, in reliance upon information concerning market transactions and quotations from recognized municipal securities dealers.

Principal Funds, Inc.  PRICING OF FUND SHARES  127 
www.principal.com     


Other securities that are traded on the over-the-counter market are valued at their closing bid prices. Each Fund will determine the market value of individual securities held by it, by using prices provided by one or more professional pricing services which may provide market prices to other funds, or, as needed, by obtaining market quotations from independent broker-dealers. Short-term securities maturing within 60 days are valued on an amortized cost basis. Securities for which quotations are not readily available, and other assets, are valued at fair value determined in good faith under procedures established by and under the supervision of the Board of Directors.

A Fund's securities may be traded on foreign securities markets that close each day prior to the time the NYSE closes. In addition, foreign securities trading generally or in a particular country or countries may not take place on all business days in New York. The Fund has adopted policies and procedures to "fair value" some or all securities held by a Fund if significant events occur after the close of the market on which the foreign securities are traded but before the Fund's NAV is calculated. Significant events can be specific to a single security or can include events that impact a particular foreign market or markets. A significant event can also include a general market movement in the U.S. securities markets. These fair valuation procedures are intended to discourage shareholders from investing in the Fund for the purpose of engaging in market timing or arbitrage transactions. The values of foreign securities used in computing share price are determined at the time the foreign market closes. Foreign securities and currencies are converted to U.S. dollars using the exchange rate in effect at the close of the NYSE. Occasionally, events affecting the value of foreign securities occur when the foreign market is closed and the NYSE is open. The NAV of a Fund investing in foreign securities may change on days when shareholders are unable to purchase or redeem shares. If the Sub-Advisor believes that the market value is materially affected, the share price will be calculated using the policy adopted by the Fund.

Certain securities issued by companies in emerging market countries may have more than one quoted valuation at any point in time, sometimes referred to as a "local" price and a "premium" price. The premium price is often a negotiated price which may not consistently represent a price at which a specific transaction can be effected. It is the policy of the Funds to value such securities at prices at which it is expected those shares may be sold, and the Manager or any Sub-Advisor is authorized to make such determinations subject to the oversight of the Board of Directors as may from time to time be necessary.

Money Market Fund

The share price of each Class of shares of the Money Market Fund is determined at the same time and on the same days as the Funds described above. All securities held by the Money Market Fund are valued on an amortized cost basis. Under this method of valuation, a security is initially valued at cost; thereafter, the Fund assumes a constant proportionate amortization in value until maturity of any discount or premium, regardless of the impact of fluctuating interest rates on the market value of the security. While this method provides certainty in valuation, it may result in periods during which value, as determined by amortized cost, is higher or lower than the price that would be received upon sale of the security.

Use of the amortized cost valuation method by the Money Market Fund requires the Fund to maintain a dollar weighted average maturity of 90 days or less and to purchase only obligations that have remaining maturities of 397 days or less or have a variable or floating rate of interest. In addition, the Fund invests only in obligations determined by the Directors to be of high quality with minimal credit risks.

The Board of Directors has established procedures for the Money Market Fund designed to stabilize, to the extent reasonably possible, the Fund's price per share as computed for the purpose of sales and redemptions at $1.00. Such procedures include a directive to the Sub-Advisor to test price the portfolio or specific securities on a weekly basis using a mark-to-market method of valuation to determine possible deviations in the net asset value from $1.00 per share. If such deviation exceeds 1/2 of 1%, the Board of Directors promptly considers what action, if any, will be initiated. In the event the Board of Directors determines that a deviation exists which may result in material dilution or other unfair results to shareholders, it takes such corrective action as it regards as appropriate, including: sale of portfolio instruments prior to maturity; the withholding of dividends; redemptions of shares in kind; the establishment of a net asset value per share based upon available market quotations; or splitting, combining or otherwise recapitalizing outstanding shares. The Fund may also reduce the number of shares outstanding by redeeming proportionately from shareholders, without the payment of any monetary compensation, such number of full and fractional shares as is necessary to maintain the net asset value at $1.00 per share.

TAXATION OF THE FUNDS

It is a policy of the Funds to make distributions of substantially all of their respective investment income and any net realized capital gains. The Funds intend to qualify as regulated investment companies by satisfying certain requirements prescribed by Subchapter M of the Internal Revenue Code. If a Fund fails to qualify as a regulated investment company, it will be liable for taxes, significantly reducing its distributions to shareholders and eliminating shareholders' ability to treat distributions (as long or short-term capital gains) of the Fund in the manner they were received by the Fund.

All income dividends and capital gains distributions, if any, on a Fund's R-1, R-2, R-3, R-4, R-5, Institutional, and S class shares are reinvested automatically in additional shares of the same class of the same Fund. Dividends and capital gains distributions, if any, on a Fund's Class A, Class B, Class C, and Class J shares are reinvested automatically in additional shares of the same Class of shares of the same Fund unless the shareholder elects to take dividends in cash. The reinvestment will be made at the NAV determined on the first business day following the record date.

Certain Funds may purchase securities of certain foreign corporations considered to be passive foreign investment companies by the Internal Revenue Service. In order to avoid taxes and interest that must be paid by the Funds if these instruments appreciate in value, the Funds may make various elections permitted by the tax laws. However, these elections could require that the Funds recognize taxable income, which in turn must be distributed.

The Fund is required in certain cases to withhold and remit to the U.S. Treasury 30.0% of ordinary income dividends and capital gain dividends, and the proceeds of redemption of shares, paid to any shareholder 1) who has provided either an incorrect tax identification number or no number at all, 2) who is subject to backup withholding by the Internal Revenue Service for failure to report the receipt of interest or dividend income properly, or 3) who has failed to certify to the Fund that it is not subject to backup withholding or that it is a corporation or other "exempt recipient."

A shareholder recognizes gain or loss on the sale or redemption of shares of the Fund in an amount equal to the difference between the proceeds of the sales or redemption and the shareholder's adjusted tax basis in the shares. All or a portion of any loss so recognized may be disallowed if the shareholder purchases other shares of the Fund within 30 days before or after the sale or redemption. In general, any gain or loss arising from (or treated as arising from) the sale or redemption of shares of the Fund is considered capital gain or loss (long-term capital gain or loss if the shares were held for longer than one year). However, any capital loss arising from the sales or redemption of shares held for six months or less is disallowed to the extent of the amount of exempt-interest dividends received on such shares and (to the extent not disallowed) is treated as a long-term capital loss to the extent of the amount of capital gain dividends received on such shares. Capital losses in any year are deductible only to the extent of capital gains plus, in the case of a noncorporate taxpayer, $3,000 of ordinary income.

If a shareholder a) incurs a sales charge in acquiring shares of the Fund, b) disposes of such shares less than 91 days after they are acquired, and c) subsequently acquires shares of the Fund or another fund at a reduced sales charge pursuant to a right to reinvest at such reduced sales charge acquired in connection with the acquisition of the shares disposed of, then the sales charge on the shares disposed of (to the extent of the reduction in the sales charge on the shares subsequently acquired) shall not be taken into account in determining gain or loss on the shares disposed of but shall be treated as incurred on the acquisition of the shares subsequently acquired.

Shareholders should consult their own tax advisors as to the federal, state and local tax consequences of ownership of shares of the Funds in their particular circumstances.

Special Tax Considerations

Municipal Funds

Each of the Municipal Funds also intends to qualify to pay "exempt-interest dividends" to its shareholders. An exempt-interest dividend is that part of dividend distributions made by the Fund which consist of interest received by that Fund on tax-exempt Municipal Obligations. Shareholders incur no federal income taxes on exempt-interest dividends. However, these exempt-interest dividends may be taxable under state or local law. Fund shareholders that are corporations must include exempt-interest dividends in determining whether they are subject to the corporate

Principal Funds, Inc.  TAXATION OF THE FUNDS  129 
www.principal.com     


alternative minimum tax. Exempt-interest dividends that derive from certain private activity bonds must be included by individuals as a preference item in determining whether they are subject to the alternative minimum tax. The Fund may also pay ordinary income dividends and distribute capital gains from time to time. Ordinary income dividends and distributions of capital gains, if any, are taxable for federal purposes.

If a shareholder receives an exempt-interest dividend with respect to shares of the Funds held for six months or less, then any loss on the sale or exchange of such shares, to the extent of the amount of such dividend, is disallowed. If a shareholder receives a capital gain dividend with respect to shares held for six months or less, then any loss on the sale or exchange of such shares is treated as a long term capital loss to the extent the loss exceeds any exempt-interest dividend received with respect to such shares, and is disallowed to the extent of such exempt-interest dividend.

Interest on indebtedness incurred or continued by a shareholder to purchase or carry shares of this Fund is not deductible. Furthermore, entities or persons who are "substantial users" (or related persons) under Section 147(a) of the Internal Revenue Code of facilities financed by private activity bonds should consult their tax advisors before purchasing shares of the Fund.

From time to time, proposals have been introduced before Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on Municipal Obligations. If legislation is enacted that eliminates or significantly reduces the availability of Municipal Obligations, it could adversely affect the ability of the Fund to continue to pursue its investment objectives and policies. In such event, the Fund would reevaluate its investment objectives and policies.

International Funds

Some foreign securities purchased by the Funds may be subject to foreign taxes that could reduce the yield on such securities. The amount of such foreign taxes is expected to be insignificant. The Funds may from year to year make the election permitted under Section 853 of the Internal Revenue Code to pass through such taxes to shareholders. If such election is not made, any foreign taxes paid or accrued will represent an expense to each affected Fund that will reduce its investment company taxable income.

Futures Contracts and Options

As previously discussed, some of the Funds invest in futures contracts or options thereon, index options, or options traded on qualified exchanges. For federal income tax purposes, capital gains and losses on futures contracts or options thereon, index options or options traded on qualified exchanges are generally treated as 60% long-term and 40% short-term. In addition, the Funds must recognize any unrealized gains and losses on such positions held at the end of the fiscal year. A Fund may elect out of such tax treatment, however, for a futures or options position that is part of an "identified mixed straddle" such as a put option purchased with respect to a portfolio security. Gains and losses on futures and options included in an identified mixed straddle are considered 100% short-term and unrealized gains or losses on such positions are not realized at year-end. The straddle provisions of the Code may require the deferral of realized losses to the extent that a Fund has unrealized gains in certain offsetting positions at the end of the fiscal year. The Code may also require recharacterization of all or a part of losses on certain offsetting positions from short-term to long-term, as well as adjustment of the holding periods of straddle positions.

PORTFOLIO HOLDINGS DISCLOSURE

The Fund may publish month-end portfolio holdings information for each Fund's portfolio on the principal.com website and on the principalfunds.com website on the fifteenth business day of the following month. The Funds may also occasionally publish information on the website relating to specific events, such as the impact of a natural disaster, corporate debt default or similar events on portfolio holdings. In addition, composite portfolio holdings information for the Money Market Fund is published each week as of the prior week on the principalglobal.com website. It is the Fund's policy to disclose only public information regarding portfolio holdings (i.e. information published on the website or filed with the SEC), except as described below.

Policy. The Fund and Principal have adopted a policy of disclosing non-public portfolio holdings information to third parties only to the extent required by federal law, and to the following third parties, so long as such third party has agreed, or is legally obligated, to maintain the confidentiality of the information and to refrain from using such information to engage in securities transactions:

5)  To the Fund's custodian, Bank of New York, in connection with the services provided by the custodian to the 
  Fund. 

The Fund is also permitted to enter into arrangements to disclose portfolio holdings to other third parties in connection with the performance of a legitimate business purpose if such third party agrees in writing to maintain the confidentiality of the information prior to the information being disclosed. Any such written agreement must be approved by an officer of the Fund, the Manager or the Fund's sub-advisor. Approval must be based on a reasonable belief that disclosure to such other third party is in the best interests of the Fund's shareholders. If a conflict of interest is identified in connection with disclosure to any such third party, the Fund's or the Manager's Chief Compliance Officer ("CCO") must approve such disclosure, in writing before it occurs. Such third parties currently include:

APPENDIX A

Description of Bond Ratings:

Moody's Investors Service, Inc. Rating Definitions:
Long-Term Obligation Ratings

Moody's long-term obligation ratings are opinions of the relative credit risk of fixed-income obligations with an original maturity of one year or more. They address the possibility that a financial obligation will not be honored as promised. Such ratings reflect both the likelihood of default and any financial loss suffered in the event of default.

Aaa:  Obligations rated Aaa are judged to be of the highest quality, with minimal credit risk. 
Aa:  Obligations rated Aa are judged to be of high quality and are subject to very low credit risk. 
A:  Obligations rated A are considered upper-medium grade and are subject to low credit risk. 
Baa:  Obligations rated Baa are subject to moderate credit risk. They are considered medium-grade and as such 
  may possess certain speculative characteristics. 
Ba:  Obligations rated Ba are judged to have speculative elements and are subject to substantial credit risk. 
B:  Obligations rated B are considered speculative and are subject to high credit risk. 
Caa:  Obligations rated Caa are judged to be of poor standing and are subject to very high credit risk. 
Ca:  Obligations rated Ca are highly speculative and are likely in, or very near, default, with some prospect of 
  recovery of principal and interest. 
C:  Obligations rated C are the lowest rated class of bonds and are typically in default, with little prospect for 
  recovery of principal or interest. 

NOTE: Moody's appends numerical modifiers, 1, 2, and 3 to each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category, the modifier 2 indicates a mid-range ranking, and the modifier 3 indicates a ranking in the lower end of that generate rating category.

SHORT-TERM NOTES: The four ratings of Moody's for short-term notes are MIG 1, MIG 2, MIG 3, and MIG 4. MIG 1 denotes "best quality, enjoying strong protection from established cash flows." MIG 2 denotes "high quality" with "ample margins of protection." MIG 3 notes are of "favorable quality...but lacking the undeniable strength of the preceding grades." MIG 4 notes are of "adequate quality, carrying specific risk for having protection...and not distinctly or predominantly speculative."

Description of Moody's Commercial Paper Ratings:

Moody's Commercial Paper ratings are opinions of the ability to repay punctually promissory obligations not having an original maturity in excess of nine months. Moody's employs the following three designations, all judged to be investment grade, to indicate the relative repayment capacity of rated issuers:

Issuers rated Prime-1 (or related supporting institutions) have a superior capacity for repayment of short-term promissory obligations.

Issuers rated Prime-2 (or related supporting institutions) have a strong capacity for repayment of short-term promissory obligations.

134  APPENDIX A  Principal Funds, Inc. 
    1-800-222-5852 


Issuers rated Prime-3 (or related supporting institutions) have an acceptable capacity for repayment of short-term promissory obligations.

Issuers rated Not Prime do not fall within any of the Prime rating categories.

Description of Standard & Poor's Corporation's Debt Ratings:

A Standard & Poor's debt rating is a current assessment of the creditworthiness of an obligor with respect to a specific obligation. This assessment may take into consideration obligors such as guarantors, insurers, or lessees.

The debt rating is not a recommendation to purchase, sell or hold a security, inasmuch as it does not comment as to market price or suitability for a particular investor.

The ratings are based on current information furnished by the issuer or obtained by Standard & Poor's from other sources Standard & Poor's considers reliable. Standard & Poor's does not perform an audit in connection with any rating and may, on occasion, rely on unaudited financial information. The ratings may be changed, suspended, or withdrawn as a result of changes in, or unavailability of, such information, or for other circumstances.

The ratings are based, in varying degrees, on the following considerations:

l.  Likelihood of default - capacity and willingness of the obligor as to the timely payment of interest and 
  repayment of principal in accordance with the terms of the obligation; 
 
II.  Nature of and provisions of the obligation; 
 
III.  Protection afforded by, and relative position of, the obligation in the event of bankruptcy, reorganization, or 
  other arrangement under the laws of bankruptcy and other laws affecting creditor's rights. 
 
AAA:  Debt rated "AAA" has the highest rating assigned by Standard & Poor's. Capacity to pay interest and repay 
  principal is extremely strong. 
 
AA:  Debt rated "AA" has a very strong capacity to pay interest and repay principal and differs from the highest- 
  rated issues only in small degree. 
 
A:  Debt rated "A" has a strong capacity to pay interest and repay principal although they are somewhat more 
  susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher- 
  rated categories. 
 
BBB:  Debt rated "BBB" is regarded as having an adequate capacity to pay interest and repay principal. Whereas it 
  normally exhibits adequate protection parameters, adverse economic conditions or changing circumstances 
  are more likely to lead to a weakened capacity to pay interest and repay principal for debt in this category than 
  for debt in higher-rated categories. 
 
BB, B, CCC, CC:              Debt rated "BB," "B," "CCC," and "CC" is regarded, on balance, as predominantly speculative with 
                               respect to capacity to pay interest and repay principal in accordance with the terms of the 
                               obligation. "BB" indicates the lowest degree of speculation and "CC" the highest degree of 
                               speculation. While such debt will likely have some quality and protective characteristics, these are 
                               outweighed by large uncertainties or major risk exposures to adverse conditions. 
 
C:  The rating "C" is reserved for income bonds on which no interest is being paid. 
 
D:  Debt rated "D" is in default, and payment of interest and/or repayment of principal is in arrears. 
 
Plus (+) or Minus (-): The ratings from "AA" to "B" may be modified by the addition of a plus or minus sign to show 
relative standing within the major rating categories. 

Principal Funds, Inc.  APPENDIX A  135 
www.principal.com     


Provisional Ratings: The letter "p" indicates that the rating is provisional. A provisional rating assumes the successful completion of the project being financed by the bonds being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, however, while addressing credit quality subsequent to completion of the project, makes no comment on the likelihood of, or the risk of default upon failure of, such completion. The investor should exercise his own judgment with respect to such likelihood and risk.

NR:  Indicates that no rating has been requested, that there is insufficient information on which to base a rating or 
  that Standard & Poor's does not rate a particular type of obligation as a matter of policy. 

Standard & Poor's, Commercial Paper Ratings

A Standard & Poor's Commercial Paper Rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days. Ratings are graded into four categories, ranging from "A" for the highest quality obligations to "D" for the lowest. Ratings are applicable to both taxable and tax-exempt commercial paper. The four categories are as follows:

A:  Issues assigned the highest rating are regarded as having the greatest capacity for timely payment. Issues in 
  this category are delineated with the numbers 1, 2, and 3 to indicate the relative degree of safety. 
A-1:  This designation indicates that the degree of safety regarding timely payment is either overwhelming or very 
  strong. Issues that possess overwhelming safety characteristics will be given a "+" designation. 
A-2:  Capacity for timely payment on issues with this designation is strong. However, the relative degree of safety is 
  not as high as for issues designated "A-1." 
A-3:  Issues carrying this designation have a satisfactory capacity for timely payment. They are, however, 
  somewhat more vulnerable to the adverse effects of changes in circumstances than obligations carrying the 
  highest designations. 
B:  Issues rated "B" are regarded as having only an adequate capacity for timely payment. However, such 
  capacity may be damaged by changing conditions or short-term adversities. 
C:  This rating is assigned to short-term debt obligations with a doubtful capacity for payment. 
D:  This rating indicates that the issue is either in default or is expected to be in default upon maturity. 

 

The Commercial Paper Rating is not a recommendation to purchase or sell a security. The ratings are based on 

current information furnished to Standard & Poor's by the issuer and obtained by Standard & Poor's from other sources 
it considers reliable. The ratings may be changed, suspended, or withdrawn as a result of changes in or unavailability 
of, such information. 
Standard & Poor's rates notes with a maturity of less than three years as follows: 
SP-1:  A very strong, or strong, capacity to pay principal and interest. Issues that possess overwhelming safety 
  characteristics will be given a "+" designation. 
SP-2:  A satisfactory capacity to pay principal and interest. 
SP-3:  A speculative capacity to pay principal and interest.

Item 24. Persons Controlled by or Under Common Control with Registrant

The Registrant does not control and is not under common control with any person.

Item 25.

Indemnification

     Under Section 2-418 of the Maryland General Corporation Law, with respect to any proceedings against a present or former director, officer, agent or employee (a "corporate representative") of the Registrant, the Registrant may indemnify the corporate representative against judgments, fines, penalties, and amounts paid in settlement, and against expenses, including attorneys' fees, if such expenses were actually incurred by the corporate representative in connection with the proceeding, unless it is established that:

     (i) The act or omission of the corporate representative was material to the matter giving rise to the proceeding; and


1.  Was committed in bad faith; or 
2.  Was the result of active and deliberate dishonesty; or 

  (ii)  The corporate representative actually received an improper personal benefit in money, property, or services; 
or     
 
  (iii)  In the case of any criminal proceeding, the corporate representative had reasonable cause to believe that the 

act or omission was unlawful.


     If a proceeding is brought by or on behalf of the Registrant, however, the Registrant may not indemnify a corporate representative who has been adjudged to be liable to the Registrant. Under the Registrant's Articles of Incorporation and Bylaws, directors and officers of Registrant are entitled to indemnification by the Registrant to the fullest extent permitted under Maryland law and the Investment Company Act of 1940. Reference is made to Article VI, Section 7 of the Registrant's Articles of Incorporation, Article 12 of Registrant's Bylaws and Section 2-418 of the Maryland General Corporation Law.

     The Registrant has agreed to indemnify, defend and hold the Distributors, their officers and directors, and any person who controls the Distributors within the meaning of Section 15 of the Securities Act of 1933, free and harmless from and against any and all claims, demands, liabilities and expenses (including the cost of investigating or defending such claims, demands or liabilities and any counsel fees incurred in connection therewith) which the Distributors, their officers, directors or any such controlling person may incur under the Securities Act of 1933, or under common law or otherwise, arising out of or based upon any untrue statement of a material fact contained in the Registrant's registration statement or prospectus or arising out of or based upon any alleged omission to state a material fact required to be stated in either thereof or necessary to make the statements in either thereof not misleading, except insofar as such claims, demands, liabilities or expenses arise out of or are based upon any such untrue statement or omission made in conformity with information furnished in writing by the Distributors to the Registrant for use in the Registrant's registration statement or prospectus: provided, however, that this indemnity agreement, to the extent that it might require indemnity of any person who is also an officer or director of the Registrant or who controls the Registrant within the meaning of Section 15 of the Securities Act of 1933, shall not inure to the benefit of such officer, director or controlling person unless a court of competent jurisdiction shall determine, or it shall have been determined by controlling precedent that such result would not be against public policy as expressed in the Securities Act of 1933, and further provided, that in no event shall anything contained herein be so construed as to protect the Distributors against any liability to the Registrant or to its security holders to which the Distributors would otherwise be subject by reason of willful misfeasance, bad faith, or gross negligence, in the performance of their duties, or by reason of their reckless disregard of their obligations under this Agreement. The Registrant's agreement to indemnify the Distributors, their officers and directors and any such controlling person as aforesaid is expressly conditioned upon the Registrant being promptly notified of any action brought against the Distributors, their officers or directors, or any such controlling person, such notification to be given by letter or telegram addressed to the Registrant.

     Principal Management Corporation ("PMC") serves as investment adviser and dividend disbursing and transfer agent for Principal Variable Contracts Funds, Inc.
