Dear Shareholder: 

       A Special Meeting of Shareholders of Principal Funds, Inc. (“PFI”) will be held at 680 8th Street, Des Moines, Iowa 50392-2080, on 

July 15, 2010 at 10 a.m., Central Time. 

       At the meeting, shareholders of the LargeCap Blend Fund I (the “Acquired Fund”) will be asked to consider and approve a Plan of 

Acquisition (the “Plan”) providing for the reorganization of the LargeCap Blend Fund I into the LargeCap S&P 500 Index Fund (the 

“Acquiring Fund”). Each of these Funds is a separate series or fund of PFI. 

       Under the Plan: (i) the Acquiring Fund will acquire all the assets, subject to all the liabilities, of the Acquired Fund in exchange for 

shares of the Acquiring Fund; (ii) the Acquiring Fund shares will be distributed to the shareholders of the Acquired Fund; and (iii) the 

Acquired Fund will liquidate and terminate (the “Reorganization”). As a result of the Reorganization, each shareholder of the Acquired Fund 

will become a shareholder of the Acquiring Fund. The total value of all shares of the Acquiring Fund issued in the Reorganization will equal 

the total value of the net assets of the Acquired Fund. The number of full and fractional shares of the Acquiring Fund received by a 

shareholder of the Acquired Fund will be equal in value to the value of that shareholder’s shares of the Acquired Fund as of the close of 

regularly scheduled trading on the New York Stock Exchange (“NYSE”) on the closing date of the Reorganization. Holders of Class A, 

Class C, Class J, Class R-1, Class R-2, Class R-3, Class R-4, Class R-5 and Institutional Class shares of the Acquired Fund will receive, 

respectively, Class A, Class C, Class J, Class R-1, Class R-2, Class R-3, Class R-4, Class R-5 and Institutional Class shares of the Acquiring 

Fund. Holders of Class B shares of the Acquired Fund will receive Class A shares of the Acquiring Fund. The Reorganization is expected to 

occur as of the close of regularly scheduled trading on the NYSE on July 23, 2010. All share classes of the Acquired Fund will vote in the 

aggregate and not by class with respect to the Reorganization. 

       The Board of Directors of PFI believes that the Reorganization will serve the best interests of shareholders of both the Acquired and 

Acquiring Funds. The Funds have the same investment objectives in that both Funds seek to provide long-term growth of capital. The Funds 

also have similar principal policies and risks in that both invest primarily in largecap securities within the capitalization range of the S&P 500 

Index (the “Index”), with the Acquiring Fund attempting to match the Index and the Acquired Fund attempting to outperform the Index. The 

Acquiring Fund has lower advisory fee rates and lower expense ratios than the Acquired Fund and has outperformed the Acquired Fund over 

the one, three, and five year periods ended December 31, 2009. Moreover, the Reorganization may be expected to afford shareholders of the 

Acquired Fund, on an ongoing basis, greater prospects for growth and efficient management. Combining the Funds will not result in any 

dilution of the interests of existing shareholders of the Funds. 

       The value of your investment will not be affected by the Reorganization. Furthermore, in the opinion of legal counsel, no gain or loss 

will be recognized by any shareholder for federal income tax purposes as a result of the Reorganization. 

*****

       Enclosed you will find a Notice of Special Meeting of Shareholders, a Proxy Statement/Prospectus, and a proxy card for shares of the 

Acquired Fund you owned as of April 26, 2010, the record date for the Meeting. The Proxy Statement/Prospectus provides background 

information and describes in detail the matters to be voted on at the Meeting. 

       The Board of Directors has unanimously voted in favor of the proposed Reorganization and recommends that you vote FOR the 

Proposal. 

       In order for shares to be voted at the Meeting, we urge you to read the Proxy Statement/Prospectus and then complete and mail 

your proxy card(s) in the enclosed postage-paid envelope, allowing sufficient time for receipt by us by July 14, 2010. As a

INTRODUCTION
This Proxy Statement/Prospectus is being furnished to shareholders of the Acquired Fund to provide information regarding the Plan and
the Reorganization.
Principal Funds, Inc. PFI is a Maryland corporation and an open-end management investment company registered with the SEC under
the 1940 Act. PFI currently offers 67 separate series or funds (the “PFI Funds”), including the Acquired and Acquiring Funds. The sponsor of
PFI is Principal Life Insurance Company (“Principal Life”), and the investment advisor to the PFI Funds is Principal Management
Corporation (“PMC”). Principal Funds Distributor, Inc. (the “Distributor” or “PFD”) is the distributor for all share classes of the Acquired
and Acquiring Funds. Principal Life, an insurance company organized in 1879 under the laws of Iowa, PMC and PFD are indirect, wholly-
owned subsidiaries of Principal Financial Group, Inc. (“PFG”). Their address is the Principal Financial Group, Des Moines, Iowa 50392-
2080.
Investment Management. Pursuant to an investment advisory agreement with PFI with respect to the Acquired and Acquiring Funds,
PMC provides investment advisory services and certain corporate administrative services to the Funds. As permitted by the investment
advisory agreement, PMC has entered into sub-advisory agreements with respect to the Acquired and Acquiring Funds as follows:
Acquired Fund	Sub-Advisor
LargeCap Blend Fund I	Goldman Sachs Asset Management, L.P. (“Goldman Sachs” or "GSAM")
Acquiring Fund	Sub-Advisor
LargeCap S&P 500 Index Fund	Principal Global Investors, LLC (“PGI”)
PMC and each sub-advisor are registered with the SEC as investment advisors under the Investment Advisers Act of 1940.
Goldman Sachs is located at 32 Old Slip, New York, NY 10005.
PGI is located at 801 Grand Avenue, Des Moines, IA 50392. PGI is an affiliate of PFG.
THE REORGANIZATION
At its meeting held on March 8, 2010, the Board, including all the Directors who are not “interested persons” (as defined in the 1940
Act) of PFI (the “Independent Directors”), approved the Reorganization pursuant to the Plan providing for the combination of the Acquired
Fund into the Acquiring Fund. The Board concluded that the Reorganization is in the best interests of the Acquired Fund and the Acquiring
Fund and that the interests of existing shareholders of the Funds will not be diluted as a result of the Reorganization. The factors that the
Board considered in deciding to approve the Reorganization are discussed below under “Information About the Reorganization – Board
Consideration of the Reorganization.”
The Reorganization contemplates: (i) the transfer of all the assets, subject to all of the liabilities, of the Acquired Fund to the Acquiring
Fund in exchange for shares of the Acquiring Fund; (ii) the distribution to Acquired Fund shareholders of the Acquiring Fund shares; and (iii)
the liquidation and termination of the Acquired Fund. As a result of the Reorganization, each shareholder of the Acquired Fund will become
a shareholder of the Acquiring Fund. In the Reorganization, the Acquiring Fund will issue a number of shares with a total value equal to the
total value of the net assets of the Acquired Fund, and each shareholder of the Acquired Fund will receive a number of full and fractional
shares of the Acquiring Fund with a value equal to the value of that shareholder’s shares of the Acquired Fund, as of the close of regularly
scheduled trading on the NYSE on the closing date of the Reorganization (the “Effective Time”). The closing date of the Reorganization is
expected to be July 23, 2010. Holders of Class A, Class C, Class J, Class R-1, Class R-2, Class R-3, Class R-4, Class R-5 and Institutional
Class shares of the Acquired Fund will receive, respectively, Class A, Class C, Class J, Class R-1, Class R-2, Class R-3, Class R-4, Class R-5
and Institutional Class shares of the Acquiring Fund. Holders of Class B shares of the Acquired Fund will receive Class A shares of the
Acquiring Fund. The terms and conditions of the Reorganization are more fully described below in this Proxy Statement/Prospectus and in
the Form of Plan of Acquisition, which is attached hereto as Appendix A.
The Board of Directors of PFI believes that the Reorganization will serve the best interests of shareholders of both the Acquired and
Acquiring Funds. The Funds have the same investment objectives in that both Funds seek to provide long-term growth of capital. The Funds
also have similar principal policies and risks in that both invest primarily in largecap securities within the capitalization range of the S&P 500
Index (the “Index”), with the Acquiring Fund attempting to match the Index and the Acquired Fund attempting to outperform the Index. The
Acquiring Fund has lower advisory fee rates and lower expense ratios than the Acquired Fund and has outperformed the Acquired Fund over
the one, three, and five year periods ended December 31, 2009. Moreover, the Reorganization may be expected to afford shareholders of the
Acquired Fund, on an ongoing basis, greater prospects for growth and efficient management. Combining the Funds will not result in any
dilution of the interests of existing shareholders of the Funds.
In the opinion of legal counsel, the Reorganization will qualify as a tax-free reorganization and, for federal income tax purposes, no gain
or loss will be recognized as a result of the Reorganization by the Acquired or Acquiring Fund shareholders. See “Information About the
Reorganization – Federal Income Tax Consequences.”
The Reorganization will not result in any material change in the purchase and redemption procedures followed with respect to the
distribution of shares. See “Additional Information About the Funds – Purchases, Redemptions and Exchanges of Shares.”

The Acquired Fund is expected to achieve the greatest benefit from the Reorganization and, therefore, will pay all expenses and out-of-
pocket fees incurred in connection with the Reorganization, including printing, mailing, and legal fees. These expenses and fees are expected
to total $104,900. Assuming the Acquiring Fund experiences the expense ratios shown in the Annual Fund Operating Expenses table,
shareholders of the Acquired Fund may expect to recover the estimated expenses of the Reorganization in one year. Further, the Acquired
Fund will also pay any trading costs associated with disposing of any portfolio securities of the Acquired Fund that would not be compatible
with the investment objectives and strategies of the Acquiring Fund and reinvesting the proceeds in securities that would be compatible. The
Acquired Fund is expected to dispose of approximately 9% of its portfolio securities. The trading costs are estimated to be $397,000 with an
approximate gain of $5,427,000 on a U.S. GAAP basis. The per share capital gain is estimated to be $0.04.
PROPOSAL:
APPROVAL OF A PLAN OF ACQUISITION PROVIDING
FOR THE REORGANIZATION OF THE
LARGECAP BLEND FUND I
INTO THE LARGECAP S&P 500 INDEX FUND
Shareholders of the LargeCap Blend Fund I (the “Acquired Fund”) are being asked to approve the reorganization of the Acquired Fund
into the LargeCap S&P 500 Index Fund (the “Acquiring Fund.)
Comparison of Acquired and Acquiring Funds
The following table provides comparative information with respect to the Acquired and Acquiring Funds. As indicated in the table, the
Funds have the same investment objectives in that both Funds seek to provide long-term growth of capital. The Funds also have similar
principal policies and risks in that both invest primarily in largecap securities. The Funds differ principally in that the Acquiring Fund is an
index fund that is passively managed and tracks the performance of the S&P 500 Index (the “Index”), while the Acquired Fund is actively
managed and seeks to outperform the Index. The Funds differ further in that the Acquiring Fund may use derivatives (stock index futures and
options) as a substitute for the sale or purchase of securities.

	stock performance.
	Over the long-term, PGI seeks a very close correlation between
	performance of the Fund, before expenses, and that of the S&P
	500. It is unlikely that a perfect correlation of 1.00 will be
	achieved. The correlation between Fund and Index performance
	may be affected by the Fund’s expenses, changes in securities
	markets, changes in the composition of the Index and the timing of
	purchases and sales of Fund shares.
	Because of the difficulty and expense of executing relatively small
	stock trades, the Fund may not always be invested in the less
	heavily weighted S&P 500 stocks. At times, the Fund’s portfolio
	may be weighted differently from the S&P 500, particularly if the
	Fund has a small level of assets to invest. In addition, the Fund’s
	ability to match the performance of the S&P 500 is affected to
	some degree by the size and timing of cash flows into and out of
	the Fund. The Fund is managed to attempt to minimize such
	effects.
	PGI reserves the right to omit or remove any of the S&P 500
	stocks from the Fund if it determines that the stock is not
	sufficiently liquid. In addition, a stock might be excluded or
	removed from the Fund if extraordinary events or financial
	conditions lead PGI to believe that it should not be a part of the
	Fund’s assets. PGI may also elect to omit any S&P 500 stocks
	from the Fund if such stocks are issued by an affiliated company.

	trademarks of The McGraw-Hill Companies, Inc. and have been
	licensed by Principal. The Fund is not sponsored, endorsed, sold,
	or promoted by Standard & Poor’s and Standard & Poor’s makes
	no representation regarding the advisability of investing in the
	Fund.

Temporary Defensive Investing:
For temporary defensive purposes in times of unusual or adverse market, economic, or political conditions, each Fund may invest up to
100% of its assets in cash and cash equivalents. In taking such defensive measures, either Fund may fail to achieve its investment
objective.
Fundamental Investment Restrictions:
The Funds are subject to nearly identical fundamental investment restrictions, the difference being that the Acquiring Fund is subject to
restriction of a concentration of its investments in a particular industry only to the extent that the Index also is so concentrated. These
fundamental restrictions deal with such matters as the issuance of senior securities, purchasing or selling real estate or commodities,
borrowing money, making loans, underwriting securities of other issuers, diversification or concentration of investments, and short sales of
securities. The fundamental investment restrictions of the Funds are described in the Statement of Additional Information.
The investment objective of each Fund may be changed by the Board of Directors of PFI without shareholder approval.
Additional information about the investment strategies and the types of securities in which the Funds may invest is discussed below
under “Certain Investment Strategies and Related Risks of the Funds” as well as in the Statement of Additional Information.
The Statement of Additional Information provides further information about the portfolio manager(s) for each Fund, including
information about compensation, other accounts managed and ownership of Fund shares.
Fees and Expenses of the Funds
The tables below compare the fees and expenses of the shares of the Acquired and Acquiring Funds. In the Reorganization, the holders
of Class R-1, Class R-2, Class R-3, Class R-4, class R-5 ("Retirement Class shares"), Class A, Class C, Class J, and Institutional Class shares
of the Acquired Fund will receive, respectively, Class R-1, Class R-2, Class R-3, Class R-4, Class R-5, Class J, and Institutional Class shares
of the Acquiring Fund. Holders of Class B shares of the Acquired Fund will receive Class A shares of the Acquiring Fund

(1)	PMC has contractually agreed to limit the Acquired Fund's Management Fees through the period ending February 28, 2011. The fee
	waiver will reduce the Acquired Fund's Management Fees by 0.01% (expressed as a percent of average net assets on an annualized
	basis).
(2)	PMC has contractually agreed to limit the Acquiring Fund’s expenses attributable to Class C shares and, if necessary, pay expenses
	normally payable by the Acquiring Fund, excluding interest expense, through the period ending February 28, 2011. The expense limit

	The costs associated with the Reorganization are not reflected in the Annual Fund Operating Expenses table. The Acquired Fund will
pay the costs associated with the Reorganization which are estimated to be $104,900. Assuming the Acquiring Fund experiences the expense
ratios in the above table, shareholders of the Acquired Fund may expect the Acquiring Fund to recover the estimated expenses of the
Reorganization in one year.
	Examples: The following examples are intended to help you compare the costs of investing in shares of the Acquired and Acquiring
Funds. The examples assume that fund expenses continue at the rates shown in the table above, that you invest $10,000 in the particular fund
for the time periods indicated and that all dividends and distributions are reinvested. The examples also assume that your investment has a
5% return each year. The examples also take into account the relevant contractual expense limit until the date of expiration. The examples
should not be considered a representation of future expense of the Acquired or Acquiring fund. Actual expense may be greater or
less than those shown.

Portfolio Turnover 

       The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio 

turnover rate may indicate higher transaction costs and may result in higher taxes for shareholders who hold Fund shares in a taxable account. 

These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most 

recent fiscal year, the portfolio turnover rate for the Acquired Fund was 94.4% of the average value of its portfolio while the portfolio 

turnover rate for the Acquiring Fund was 7.6%. 

Investment Management Fees/Sub-Advisory Arrangements

         Each Fund pays its investment advisor, PMC, an advisory fee which for each Fund is calculated as a percentage of the Fund’s average 

daily net assets pursuant to the following fee schedule: 

LargeCap Blend Fund I		LargeCap S&P 500 Index Fund
(Acquired Fund)		(Acquiring Fund)
First $500 million	0.45%
Next $500 million	0.43%
Next $500 million	0.40%	All assets	0.15%
Over $1.5 billion	0.41%

       Sub-Advisory fees for each Fund are paid by PMC. As a result of the Reorganization, the assets of the Acquired Fund, which is managed 

by a sub-advisor unaffiliated with PMC, will be transferred to the Acquiring Fund, which is managed by an affiliated sub-advisor. 

Consequently, the Reorganization may be expected to benefit PMC by increasing, with respect to such assets, the amount of the fees that are 

retained by PMC and its affiliate rather than paid to an unaffiliated sub-advisor. 

       A discussion of the basis of the Board’s approval of the advisory and sub-advisory agreements with respect to the Acquired and 

Acquiring Funds is available in PFI’s Annual Report to Shareholders for the fiscal year ended October 31, 2009. 

Comparison of Principal Investment Risks 

       In deciding whether to approve the Reorganization, shareholders should consider the amount and character of investment risk involved 

in the respective investment objectives and strategies of the Acquired and Acquiring Funds. Because the Funds have similar investment 

objectives and substantially similar principal policies, the Funds’ risks are substantially similar. As described below, the Funds also have 

some different risks. 

Risks Applicable to both Funds: 

Equity Securities Risk. Equity securities (common, preferred, and convertible preferred stocks and securities whose values are tied to the 

price of stocks, such as rights, warrants and convertible debt securities) could decline in value if the issuer's financial condition declines or in 

response to overall market and economic conditions. A fund's principal market segment(s), such as large cap, mid cap or small cap stocks, or 

growth or value stocks, may underperform other market segments or the equity markets as a whole. Investments in smaller companies and 

mid-size companies may involve greater risk and price volatility than investments in larger, more mature companies. 

Underlying Fund Risk. An underlying fund to a fund of funds may experience relatively large redemptions or investments as the fund of 

funds periodically reallocates or rebalances its assets. These transactions may cause the underlying fund to sell portfolio securities to meet 

such redemptions, or to invest cash from such investments, at times it would not otherwise do so, and may as a result increase transaction 

costs and adversely affect underlying fund performance. 

Risks Applicable to the Acquired Fund: 

Growth Stock Risk. Market prices of growth stocks are often more sensitive than other securities to earnings expectations. 

Value Stock Risk. The market may not recognize the intrinsic value of value stocks for a long time, or they may be appropriately priced at 

the time of purchase. 

Risk Applicable to the Acquiring Fund: 

Derivatives Risk. Transactions in derivatives (such as options, futures, and swaps) may increase volatility, cause the liquidation of portfolio 

positions when not advantageous to do so and produce disproportionate losses. Certain Fund transactions, such as reverse repurchase 

agreements, loans of portfolio securities, and the use of when-issued, delayed delivery or forward commitment transactions, or derivative 

instruments, may give rise to leverage, causing the Fund to be more volatile than if it had not been leveraged. 

Performance

         The following information provides an indicator of the risks of investing in the Funds. The bar chart below shows how the Acquired 

Fund’s total return has varied year-by-year, while the table below shows each Fund’s performance over time (along with the returns of a 

broad-based market index for reference). Annual returns do not reflect any applicable sales charges and would be lower if they did. A Fund's 

past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. You may get updated

INFORMATION ABOUT THE REORGANIZATION
Plan of Acquisition
The terms of the Plan are summarized below. The summary is qualified in its entirety by reference to the Form of the Plan which is
attached as Appendix A to this Proxy Statement/Prospectus.
Under the Plan, the Acquiring Fund will acquire all the assets, subject to all the liabilities, of the Acquired Fund. We expect that the
closing date will be July 23, 2010, or such earlier or later date as PMC may determine, and that the Effective Time of the Reorganization will
be as of the close of regularly scheduled trading on the NYSE (normally 3:00 p.m., Central Time) on that date. Each Fund will determine its
net asset values as of the close of trading on the NYSE using the procedures described in its then current prospectus (the procedures
applicable to the Acquired Fund and the Acquiring Fund are identical). The Acquiring Fund will issue to the Acquired Fund a number of
shares of each share class with a total value equal to the total value of the net assets of the corresponding share class of the Acquired Fund
outstanding at the Effective Time.
Immediately after the Effective Time, the Acquired Fund will distribute to its shareholders Acquiring Fund shares of the same class as
the Acquired Fund shares each shareholder owns in exchange for all Acquired Fund shares of that class. Acquired Fund shareholders will
receive a number of full and fractional shares of the Acquiring Fund that are equal in value to the value of the shares of the Acquired Fund
that are surrendered in the exchange. In connection with the exchange, the Acquiring Fund will credit on its books an appropriate number of
its shares to the account of each Acquired Fund shareholder, and the Acquired Fund will cancel on its books all its shares registered to the
account of that shareholder. After the Effective Time, the Acquired Fund will be dissolved in accordance with applicable law.
The Plan may be amended, but no amendment may be made which in the opinion of the Board would materially adversely affect the
interests of the shareholders of the Acquired Fund. The Board may abandon and terminate the Plan at any time before the Effective Time if it
believes that consummation of the transactions contemplated by the Plan would not be in the best interests of the shareholders of either of the
Funds.
Under the Plan, the Acquired Fund will pay all expenses and out-of-pocket fees incurred in connection with the Reorganization.
If the Plan is not consummated for any reason, the Board will consider other possible courses of action.
Reasons for the Reorganization
The Board of Directors of PFI believes that the Reorganization will serve the best interests of shareholders of both the Acquired and
Acquiring Funds. The Funds have the same investment objectives in that both Funds seek to provide long-term growth of capital. The Funds
also have similar principal policies and risks in that both invest primarily in largecap securities within the capitalization range of the S&P 500
Index (the “Index”), with the Acquiring Fund attempting to match the Index and the Acquired Fund attempting to outperform the Index. The
Acquiring Fund has lower advisory fee rates and lower expense ratios than the Acquired Fund and has outperformed the Acquired Fund over
the one, three, and five year periods ended December 31, 2009. Moreover, the Reorganization may be expected to afford shareholders of the
Acquired Fund, on an ongoing basis, greater prospects for growth and efficient management. Combining the Funds will not result in any
dilution of the interests of existing shareholders of the Funds.
Board Consideration of the Reorganization
At its March 8, 2010 meeting, the Board considered information presented by PMC, and the Independent Directors were assisted by
independent legal counsel. The Board requested and evaluated such information as it deemed necessary to consider the Reorganization. At
the meeting, the Board unanimously approved the Reorganization after concluding that participation in the Reorganization is in the best
interests of the Acquired Fund and the Acquiring Fund and that the interests of existing shareholders of the Funds will not be diluted as a
result of the Reorganization.
In determining whether to approve the Reorganization, the Board made inquiry into a number of matters and considered, among others,
the following factors, in no order of priority:
(1)	the investment objectives and principal investment strategies and risks of the Funds;
(2)	nearly identical fundamental investment restrictions;
(3)	estimated trading costs associated with disposing of any portfolio securities of the Acquired Fund and reinvesting the proceeds in
	connection with the Reorganization;
(4)	expense ratios and available information regarding the fees and expenses of the Funds;
(5)	comparative investment performance of and other information pertaining to the Funds
(6)	the prospects for growth of and for achieving economies of scale by the Acquired Fund in combination with the Acquiring Fund;
(7)	the absence of any material differences in the rights of shareholders of the Funds;
(8)	the financial strength, investment experience and resources of PGI, which currently serves as sub-advisor to the Acquiring Fund;
(9)	any direct or indirect benefits expected to be derived by PMC and its affiliates from the Reorganization;

(10) the direct or indirect federal income tax consequences of the Reorganization, including the expected tax-free nature of the
	Reorganization and the impact of any federal income tax loss carry forwards and the estimated capital gain or loss expected to be
	incurred in connection with disposing of any portfolio securities that would not be compatible with the investment objectives and
	strategies of the Acquiring Fund;
(11) the fact that the Reorganization will not result in any dilution of Acquired or Acquiring Fund shareholder values;
(12) the terms and conditions of the Plan; and
(13) possible alternatives to the Reorganization.
The Board’s decision to recommend approval of the Reorganization was based on a number of factors, including the following:
(1)	it should be reasonable for shareholders of the Acquired Fund to have similar investment expectations after the Reorganization
	because the Funds have the same investment objectives and substantially similar principal investment strategies and risks;
(2)	PGI as sub-advisor responsible for managing the assets of the Acquiring Fund may be expected to provide high quality investment
	advisory services and personnel for the foreseeable future;
(3)	the Acquiring Fund has lower advisory fee rates and lower overall expense ratios than the Acquired Fund;
(4)	the Acquiring Fund has outperformed the Acquired fund for the one-, three- and five-year period ended December 31, 2009; and
(5)	the combination of the Acquired and Acquiring Funds may be expected to afford shareholders of the Acquired Fund on an ongoing
	basis greater prospects for growth and efficient management.
Description of the Securities to Be Issued
PFI is a Maryland corporation that is authorized to issue its shares of common stock in separate series and separate classes of series.
Each of the Acquired and Acquiring Funds is a separate series of PFI, and the Class A, Class C, Class J, Class R-1, Class R-2, Class R-3,
Class R-4, Class R-5 and Institutional Class shares of common stock of the Acquiring Fund to be issued in connection with the
Reorganization represent interests in the assets belonging to that series and have identical dividend, liquidation and other rights, except that
expenses allocated to a particular series or class are borne solely by that series or class and may cause differences in rights as described
herein. Expenses related to the distribution of, and other identified expenses properly allocated to, the shares of a particular series or class are
charged to, and borne solely by, that series or class, and the bearing of expenses by a particular series or class may be appropriately reflected
in the net asset value attributable to, and the dividend and liquidation rights of, that series or class.
All shares of PFI have equal voting rights and are voted in the aggregate and not by separate series or class of shares except that shares
are voted by series or class: (i) when expressly required by Maryland law or the 1940 Act and (ii) on any matter submitted to shareholders
which the Board has determined affects the interests of only a particular series or class.
The share classes of the Acquired Fund have the same rights with respect to the Acquired Fund that the share classes of the Acquiring
Fund have with respect to the Acquiring Fund.
Shares of both Funds, when issued, have no cumulative voting rights, are fully paid and non-assessable, have no preemptive or
conversion rights and are freely transferable. Each fractional share has proportionately the same rights as are provided for a full share.
Federal Income Tax Consequences
To be considered a tax-free “reorganization” under Section 368 of the Internal Revenue Code of 1986, as amended (the “Code”), a
reorganization must exhibit a continuity of business enterprise. Because the Acquiring Fund will use a portion of the Acquired Fund’s assets
in its business and will continue the Acquired Fund’s historic business, the combination of the Acquired Fund into the Acquiring Fund will
exhibit a continuity of business enterprise. Therefore, the combination will be considered a tax-free “reorganization” under applicable
provisions of the Code. In the opinion of tax counsel to PFI, no gain or loss will be recognized by either of the Funds or their shareholders in
connection with the combination, the tax cost basis of the Acquiring Fund shares received by shareholders of the Acquired Fund will equal
the tax cost basis of their shares in the Acquired Fund, and their holding periods for the Acquiring Fund shares will include their holding
periods for the Acquired Fund shares.
Capital Loss Carryforward. As of October 31, 2009, the Acquired Fund had an accumulated capital loss carryforward of approximately
$242,881,000 expiring between 2016 and 2017. After the Reorganization, these losses will be available to the Acquiring Fund to offset its
capital gains, although the amount of offsetting losses in any given year may be limited. As a result of this limitation, it is possible that the
Acquiring Fund may not be able to use these losses as rapidly as the Acquired Fund might have, and part of these losses may not be useable
at all. The ability of the Acquiring Fund to utilize the accumulated capital loss carryforward in the future depends upon a variety of factors
that cannot be known in advance, including the existence of capital gains against which these losses may be offset. In addition, the benefits of
any capital loss carryforward currently are available only to shareholders of the Acquired Fund. After the Reorganization, however, these
benefits will inure to the benefit of all shareholders of the Acquiring Fund.
Distribution of Income and Gains. Prior to the Reorganization, the Acquired Fund, whose taxable year will end as a result of the
Reorganization, will declare to its shareholders of record one or more distributions of all of its previously undistributed net investment
income and net realized capital gain, including capital gains on any securities disposed of in connection with the Reorganization. Such
distributions will be made to shareholders before the Reorganization. An Acquired Fund shareholder will be required to include any such
distributions in such shareholder’s taxable income. This may result in the recognition of income that could have been deferred or might never
have been realized had the Reorganization not occurred.

       The foregoing is only a summary of the principal federal income tax consequences of the Reorganization and should not be considered 

to be tax advice. There can be no assurance that the Internal Revenue Service will concur on all or any of the issues discussed above. You 

may wish to consult with your own tax advisors regarding the federal, state, and local tax consequences with respect to the foregoing matters 

and any other considerations which may apply in your particular circumstances. 

CAPITALIZATION

           The following tables show as of October 31, 2009: (i) the capitalization of the Acquired Fund; (ii) the capitalization of the Acquiring 

Fund; and (iii) the pro forma combined capitalization of the Acquiring Fund as if the Reorganization has occurred as of that date. As of 

October 31, 2009, the Acquired Fund had outstanding ten classes of shares; Class A, Class B, Class C, Class J, Institutional, Class R-1, Class 

R-2, Class R-3, Class R-4, and Class R-5. As of October 31, 2009, the Acquiring Fund had outstanding nine classes of shares; Class A, 

Class C, Class J, Institutional, Class R-1, Class R-2, Class R-3, Class R-4, and Class R-5. Holders of Class B shares of the Acquired Fund 

will receive Class A shares of the Acquiring Fund in the Reorganization. 

             The Acquired fund will pay all expenses and out-of-pocket fees incurred in connection with the Reorganization including printing, 

mailing, and legal fees. The expenses and fees the Acquired Fund will pay are expected to total $104,900. Further, the Acquired Fund will 

also pay any trading costs associated with disposing of any portfolio securities of the Acquired fund that would not be compatible with the 

investment objectives and strategies of the Acquiring Fund and reinvesting the proceeds in securities that would be compatible. The trading 

costs are estimated to be $397,000 with an approximate gain of $5,427,000 on a U.S. GAAP basis. The per share capital gain is estimated to 

be $0.04.

ADDITIONAL INFORMATION ABOUT THE FUNDS

Certain Investment Strategies and Related Risks of the Funds

         This section provides information about certain investment strategies and related risks of the Funds. The Statement of Additional 

Information contains additional information about investment strategies and their related risks. 

           Some of the principal investment risks vary between the Funds and the variations are described above. The value of each Fund’s 

securities may fluctuate on a daily basis. As with all mutual funds, as the values of each Fund’s assets rise or fall, the Fund’s share price 

changes. If an investor sells Fund shares when their value is less than the price the investor paid, the investor will lose money. As with any 

security, the securities in which the Funds invest have associated risk. 

Market Volatility. The value of a fund’s portfolio securities may go down in response to overall stock or bond market movements. Markets 

tend to move in cycles, with periods of rising prices and periods of falling prices. Stocks tend to go up and down in value more than bonds. If 

the fund’s investments are concentrated in certain sectors, its performance could be worse than the overall market. The value of an individual 

security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the 

market as a whole. It is possible to lose money when investing in the fund. 

Equity Securities. Equity securities include common stocks, preferred stocks, convertible securities, depositary receipts, rights, (a right is an 

offering of common stock to investors who currently own shares which entitle them to buy subsequent issues at a discount from the offering 

price), and warrants (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). 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. 

Management Risk. The Acquired Fund is actively managed and prepared to invest in securities, sectors, or industries differently from the 

benchmark. For the Fund, if a sub-advisor's investment strategies do not perform as expected, the Fund could underperform other funds with 

similar investment objectives or lose money. 

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. 

Repurchase Agreements. Although not a principal investment strategy, 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 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. 

Real Estate Investment Trusts. The Funds may invest in real estate investment trust securities, herein referred to as “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.
Derivatives. To the extent permitted by its investment objectives and policies, the Acquiring 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, forward contracts, 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), currency futures contracts and options, options
on currencies, and forward currency contracts for both hedging and non-hedging 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 approximate aggregate market value of the securities held or to be purchased by the Fund (denominated
or generally quoted or currently convertible into the currency). The Funds may enter into forward commitment agreements (not as a principal
investment strategy), which call for the Fund to purchase or sell a security on a future date at a fixed price. Each of the Funds may also enter
into contracts to sell its investments either on demand or at a specific interval.
Generally, no 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.
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. 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.
For currency contracts, there is also a risk of government action through exchange controls that would restrict the ability of the Fund to
deliver or receive currency.
Foreign Investing. The Funds 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, 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. To protect against future uncertainties in foreign currency exchange rates, the funds
are authorized to enter into certain foreign currency exchange transactions.
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 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. 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 Funds may invest in securities of companies with small- or mid-sized market
capitalizations but not as a principal investment strategy. 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, 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.
Underlying Funds. The Acquired and Acquiring Funds are underlying funds to certain PFI fund of funds. An underlying fund may
experience relatively large redemptions or investments as the fund of funds periodically reallocates or rebalances its assets. These
transactions may 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 and the Sub-Advisors for the funds of funds 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.

The following table shows the percentage of the outstanding shares of acquired and acquiring funds owned by the Principal LifeTime Funds
as of February 28, 2010.

Securities Lending Risk. To earn additional income, each Fund may lend portfolio securities to approved financial institutions. Risks of
such a practice include the possibility that a financial institution becomes insolvent, increasing the likelihood that the Fund will be unable to
recover the loaned security or its value. Further, the cash collateral received by the Fund in connection with such a loan may be invested in a
security that subsequently loses value.
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 a 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 Funds may take temporary defensive measures. In taking such measures, a 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 rates. Funds with high turnover rates (more than 100%)
often have higher transaction costs (that are paid by the Fund) which may lower the Fund’s 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). Turnover rates for each of the other Funds may
be found in the Fund’s Financial Highlights table.
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. You
should also be aware that the “total return” line in the Financial Highlights section reflects portfolio turnover costs.
Multiple Classes of Shares
The Board of Directors of PFI has adopted an 18f-3 Plan for each of the Funds. Under these plans, the Funds offer the following shares:
Class A, Class C, Class R-1, Class R-2, Class R-3, Class R-4, Class R-5, Class J and Institutional Class. Further, the Acquired Fund also
offers Class B shares. The shares are the same except for differences in class expenses, including any Rule 12b-1 fees and any applicable
sales charges, excessive trading and other fees.
Costs of Investing in the Funds
Fees and Expenses of the Funds
The fees and expenses of the Funds are described below. Depending on the class of your shares, you may incur one-time or ongoing fees
or both. One-time fees include sales or redemption fees. Ongoing fees are the operating expenses of a Fund and include fees paid to the
Fund’s manager, underwriter and others who provide ongoing services to the Fund. The Class R-1, R-2, R-3, R-4, and Class R-5 shares are
collectively referred to herein as the "Retirement Class shares."
Fees and expenses are important because they lower your earnings. However, lower 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.

One-time fees
Class A, Class B and Class C Shares
•	You may pay a one-time sales charge for each purchase (Class A shares) or redemption (Class B and Class C shares).
	•	Class A shares may be purchased at a price equal to the share price plus an initial sales charge. Investments of $500,000 or
		more of Class A shares of the Funds are sold without an initial sales charge but may be subject to a contingent deferred sales
		charge (CDSC) at the time of redemption.
	•	Class B and 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, Class B 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).
Institutional and Retirement Class Shares:
Institutional Class and Retirement Class Shares are sold without a front-end sales charge and do not have a contingent deferred sales
charge. There is no sales charge on Institutional Class or Retirement Class shares of the Funds purchased with reinvested dividends or other
distributions.
Class J
The Class J shares of the Funds are sold without a front-end sales charge. There is no sales charge on shares purchased with reinvested
dividends or other distributions.
If you sell your Class J shares within 18 months of purchase, a contingent deferred sales charge (CDSC) may be imposed on the shares
sold. 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 nonmonthly plans) of the
	value of the Fund account at the time, and beginning on the date, the systematic withdrawal plan is established);
•	that were redeemed from retirement plans to satisfy excess contribution rules under the Internal Revenue Code; or
An excessive trading fee 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 Fund pays ongoing fees to PMC and others who provide services to the Fund. These fees include:
•	Management Fee – Through the Management Agreement with the Fund, PMC has agreed to provide investment advisory services
	and administrative services to the Fund.
•	Other Expenses – A portion of expenses that are allocated to all classes of the Fund.
•	Distribution Fee – Each of the Funds has adopted a distribution plan under Rule 12b-1 of the 1940 Act for its Retirement Class
	shares, Class J shares, Class A shares, Class B shares and Class C shares. 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. Over time, these fees may exceed 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 Funds at cost.

Retirement Class Shares Only
•	Service Fee – PMC has entered into a Services Agreement with PFI under which PMC performs personal services for shareholders.
•	Administrative Service Fee – PMC has entered into an Administrative Services Agreement with PFI under which PMC provides
	transfer agent and corporate administrative services to the Fund. In addition, PMC has assumed the responsibility for
	communications with and recordkeeping services for beneficial owners of Fund shares.
Class A, Class B, Class C, Class J and Institutional Class shares of the Funds also pay expenses of registering and qualifying shares for
sale, the cost of producing and distributing reports and prospectuses to shareholders, and the cost of shareholder meetings held solely for
Class A, Class B, Class C, Class J and Institutional Class shares respectively.
Distribution Plans and Intermediary Compensation
Institutional Class Shares
Neither Fund has adopted a 12b-1 Plan for Institutional Class shares.
Retirement Class Shares
PFI has adopted Distribution and Service Plans under Rule 12b-1 under the 1940 Act (a “12b-1 plan”) for the Class R-1, R-2, R-3, and
R-4 shares of each Fund. Under the 12b-1 plan, the Funds will make payments from their assets attributable to the particular share class to
PFD .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 Board will
determine whether to terminate, modify, or leave unchanged the 12b-1 plan for any fund 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 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	12b-1 Fee
	R-1	0.35%
	R-2	0.30%
	R-3	0.25%
	R-4	0.10%
Retirement Plan Services. Each Fund pays a Service Fee and Administrative Services Fee to PMC for providing services to retirement
plan shareholders. PMC 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. PMC 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 funds, 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 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.
Class A, Class B, Class C and Class J Shares
Each Fund has adopted a 12b-1 plan for its Class A, Class B, Class C and Class J shares. Under the 12b-1 Plans, the Funds may make
payments from assets attributable to the particular share class to the 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.
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 Acquiring Fund is set forth below:
	Share Class	12b-1 Fee
	Class A	0.25% for Acquired Fund.
		0.15% for Acquiring Fund
	Class B	1.00%
	Class C	1.00%
	Class J	0.45%

The proceeds from the Rule 12b-1 fees paid by Class A, Class B, Class C and Class J shareholders, together with any applicable
contingent deferred sales charge, are paid to the Distributor. The Distributor generally uses 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 Distributor also uses 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.
Other Payments to Financial Intermediaries
If one mutual fund sponsor makes greater payments than another, your Financial Professional and his or her intermediary may have an
incentive to recommend one fund complex over another. Similarly, if your Financial Professional or his or her intermediary receives more
distribution assistance for one share class versus another, then they may have an incentive to recommend that share class.
Financial Professionals who deal with investors on an individual basis are typically associated with an intermediary. Financial
Professionals may receive some or all of the amounts paid to the intermediary with which he or she is associated. You can ask your Financial
Professional for information about any payments he or she or the intermediary receives from the Distributor, its affiliates or the Fund and any
services provided.
Please speak with your Financial Professional to learn more about the total amounts paid to your Financial Professional and his or her
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 Financial Professional at the time of purchase.
Although a Fund may use brokers who sell shares of the Funds 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 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 intermediary. You should ask your Financial
Professional for information about any fees and/or commissions that are charged.
Additionally, the Distributor and its affiliates will, in some cases, provide payments to reimburse directly or indirectly the costs incurred
by intermediaries and their associated Financial Professionals in connection with educational seminars and training and marketing efforts
related to the Funds for the intermediaries’ employees and representatives and/or their clients and potential clients. The costs and expenses
associated with these efforts may include travel, lodging, entertainment, and meals. The Distributor will also, in some cases, provide payment
or reimbursement for expenses associated with qualifying dealers’ conferences, transactions (“ticket”) charges, and general marketing
expenses.
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
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 all PFI 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 outstanding for 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 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 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 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.
Purchase of Fund Shares
Class A and Class C Shares
Shares of the Funds are generally purchased through persons employed by or affiliated with broker/dealer firms (“‘Financial
Professionals”). Financial Professionals 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 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 Financial Professional 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,
starter checks, money orders, travelers' checks, credit card checks, and foreign checks.
To eliminate the need for safekeeping, Principal Funds will not issue certificates for shares.
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 or Portfolio 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; 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 Funds 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. Each 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.

Your Financial Professional can help you buy shares of the Funds by mail, through bank wire, direct deposit, or AIP. 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 Financial Professional 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 can request 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 the transfer agent’s bank. 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 (“AIP”)
Your Financial Professional can help you establish an AIP. 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 AIP when you open your account. Minimum
monthly purchase is $100 per Fund.
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 provided or made by Principal Funds, a Fund, Principal, any Sub-Advisor, or PFD.
Class B Shares
Class B shares of the Funds are no longer be available for purchase, except through exchanges and dividend reinvestments as discussed
below. Effective May 12, 2010, exchanges cannot be made into the Acquired Fund. Class B shareholders may continue to hold such shares
until they automatically convert to Class A shares under the existing conversion schedule (based on purchase date), as described below.
Shareholders who owned Class B shares on February 26, 2010 will still receive dividend reinvestments and may continue to exchange their
shares for other Class B Fund shares in accordance with the Funds' current policies. Effective on and after the Closing Date, Class B
shareholders who have an automated investment plan in Class B shares (such as Automatic Investment Plan (“AIP”) or automatic exchange
election), will have such recurring investments automatically redirected into Class A shares of the same Fund with the applicable Class A
sales charge (load). All other features of Class B shares, including Rule 12b-1 distribution and/or service fees, contingent deferred sales
charge schedules and conversion features, remain unchanged and continue in effect. We may modify these policies in the future.
Institutional Class Shares
Only eligible purchasers may buy Institutional Class shares of the Funds. At the present time, eligible purchasers include but are not
limited to:
•	retirement and pension plans to which Principal Life Insurance Company (“Principal Life”) provides recordkeeping services;
•	separate accounts of Principal Life;
•	Principal Life or any of its subsidiaries or affiliates;
•	any fund distributed by Principal Funds Distributor, Inc. if the fund seeks to achieve its investment objective by investing primarily
	in shares of mutual funds;
•	clients of Principal Global Investors, LLC.;
•	sponsors, recordkeepers, or administrators of wrap account or mutual fund asset allocation programs or participants in those
	programs;
•	certain pension plans;
•	certain retirement account investment vehicles administered by foreign or domestic pension plans;
•	an investor who buys shares through an omnibus account with certain intermediaries, such as a broker-dealer, bank, or other
	financial institution, pursuant to a written agreement; and
•	certain institutional clients that have been approved by Principal Life for purposes of providing plan record keeping.
PMC reserves the right to broaden or limit the designation of eligible purchasers. Not all of the Funds are offered in every state. Please
check with your financial advisor or our home office for state availability.

Shares may be purchased from the Distributor. 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 (generally an omnibus account or an
institutional investor). Each investment is confirmed by sending the investor a statement of 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 PMC’s
opinion, may be disruptive to the Fund. For these purposes, PMC 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. PMC may recommend to the Board, and the Board may elect, to
close certain funds to new and existing investors.
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 provided or made by PFI, a Fund, PMC, any Sub-Advisor, or PFD.
Retirement Class Shares
The Retirement Class shares may be purchased through retirement plans, though not all plans offer each Fund. Such plans may impose
fees in addition to those charged by the Funds. 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 professional to help you decide which share class is best for you.
Only eligible purchasers may buy Retirement Class shares of the Funds. At the present time, eligible purchasers include but are not
limited to:
•	retirement and pension plans to which Principal Life Insurance Company ("Principal Life") provides recordkeeping services;
•	separate accounts of Principal Life;
•	Principal Life or any of its subsidiaries or affiliates;
•	any fund distributed by Principal Funds Distributor, Inc. if the fund seeks to achieve its investment objective by investing primarily

•	can investor who buys shares through an omnibus account with certain intermediaries, such as a broker-dealer, bank, or other
	financial institution, pursuant to a written agreement; and
•	certain retirement plan clients that have an approved organization for purposes of providing plan record keeping services.
PMC reserves the right to broaden or limit the designation of eligible purchasers. Not all of the Funds are offered in every state. Please
check with your financial advisor or our home office for state availability.
Shares may be purchased from Principal Funds Distributor, Inc. The Distributor is an affiliate of Principal Life Insurance Company and
with it are subsidiaries of Principal Financial Group, Inc. and members of the Principal Financial Group. There are no sales charges on R-1,
R-2, R-3, R-4, and R-5 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 (generally an omnibus account or an plan level account). Each investment is
confirmed by sending the investor a statement of 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

Class J Shares
Class J shares are currently available only through registered representatives of:
•	Princor who are also employees of Principal Life (These registered representatives are sales counselors of Principal Connection, a
	distribution channel used to directly market certain products and services of the companies of the Principal Financial Group.);
•	selected broker-dealers selling Class J shares in conjunction with health savings accounts; and
•	selected broker-dealers that have entered into a selling agreement to offer Class J shares.
For more information about Class J shares of the Funds, please call the Connection at 1-800-247-8000, extension 411.
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.
Each Fund requires a minimum initial investment of $1,000. Subsequent investment minimums are $100.
•	PFI may reject or cancel any purchase orders for any reason. For example, PFI 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, PFI may reject any purchase orders from market timers or investors that, in
	PMC’s opinion, may be disruptive to the Funds. For these purposes, PMC may consider an investor's trading history in the Funds
	or other Funds sponsored by Principal Life and accounts under common ownership or control. PMC 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 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. If you are making subsequent purchases into your existing Principal Funds
	Class J 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. 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.
•	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 PMC 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,
starter checks, 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 Financial Professional 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 Financial Professional 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 the transfer agent’s bank. 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 Financial Professional 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.
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 provided or made by PFI, a Fund, PMC, any Sub-Advisor, or PFD.
Redemption of Fund Shares
Class A, Class B and Class C Shares
After you place a sell order in proper form, which must be received at the transaction processing center in Canton, Massachusetts, 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 (a day when the NYSE is open for normal business) 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.
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 15 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 Funds tendered for redemption is ordinarily made by check. However, the Funds 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, each of the Funds 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 a Fund pays the redemption proceeds in kind, the redeeming shareholder might
incur brokerage or other costs in selling the securities for cash. Each 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.

Sell shares by mail
•	Send a letter or distribution form (call us for the form) which is signed by the owner/owners of the account to Principal Funds, P.O. Box
	8024, Boston, MA 02266-8024. Specify the Fund(s) and account number.
•	Specify the number of shares or the dollar amount to be sold.

	•	check is payable to a party other than the account shareholder(s), Principal Life, or a retirement plan trustee or

		* 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.

	which the shares are being sold.
•	If our phone lines are busy, you may need to send in a written sell order.
•	To sell shares the same day, the order must be received in good order before the close of normal trading on the NYSE (generally 3:00

Systematic withdrawal plans
	You may set up a systematic withdrawal plan on a monthly, quarterly, semiannual, or annual basis to:
	•	sell enough shares to provide a fixed amount of money ($100 minimum amount; the required minimum is waived to the extent
		necessary to meet the required minimum distribution as defined by the Internal Revenue Code),
	•	pay insurance or annuity premiums or deposits to Principal Life (call us for details), and
	•	provide an easy method of making monthly installment payments (if the service is available from your creditor who must supply
		the necessary forms).
	You can set up a systematic withdrawal plan by:
	•	completing the applicable section of the application, or
	•	sending us your written instructions, or
	•	completing a Systematic Withdrawal Plan Request form (available on www.PrincipalFunds.com), or
	•	calling us if you have telephone privileges on the account (telephone privileges may not be available for all types of accounts).
	Your systematic withdrawal plan continues until:
	•	you instruct us to stop or
	•	your Fund account balance is zero.
	When you set up the withdrawal plan, you select which day you want the sale made (if none is selected, the sale will be made on the
15th of the month). 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 Fund from which the systematic withdrawal is made makes no recommendation as to either the number of shares or the fixed
amount that you withdraw.
	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.
Institutional Class Shares
	Institutional Class Shares of the Funds may be redeemed 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 a Fund in proper and complete form. The Funds generally send payment for
shares sold the business day after the sell order is received. Under unusual circumstances, the Funds may suspend redemptions, or postpone
payment for more than seven days, as permitted by federal securities law.

Retirement Class Shares
Subject to any restrictions imposed by a plan, Retirement Class shares may be redeemed any day the NYSE is open. For more
information about how to sell shares of a Fund, including any charges that a plan may impose, please consult the plan.
The Funds generally sends payment for shares sold the business day after the sell order is received. Under unusual circumstances, the
Funds 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 Funds tendered for redemption is ordinarily made by check. However, the Funds 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, each of the Funds 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 a Fund pays the redemption proceeds in kind, the redeeming shareholder might
incur brokerage or other costs in selling the securities for cash. Each 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.”
Class J 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 (a day when the
NYSE is open for normal business) 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.
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.
Selling 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 15 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, Fund 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 J shares, you may reinvest the amount of the sale proceeds into any Principal Funds Class J
shares fund; shares purchased by redemption proceeds are not subject to the eighteen 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.
CDSC-Free withdrawal privilege. Sales may be subject to a CDSC. Redemption of Class J shares made through a systematic withdrawal
plan in an amount of up to 1.00% per month (measured cumulatively with respect to nonmonthly plans) of the value of the Fund account at
the time, and beginning on the date, the systematic withdrawal plan is established) may be made without a CDSC. The free withdrawal
privilege not used in a calendar year is not added to the free withdrawal privileges for any following year.

Sell shares by mail:
•	Send a distribution form (available at www.PrincipalFunds.com or by calling 1-800-222-5852) which is signed by the
	owner/owners of the account to:
	Principal Funds
	P.O. Box 55904
	Boston, MA 02205
•	Medallion Signature Guarantee* will be required if the:
•	sell order is for more than $100,000;
•	wire or ACH is being sent to a shareholder's U.S. bank account not previously authorized or the request does not include a voided
	check or deposit slip indicating a common owner between the bank account and mutual fund account;
•	check is being sent to an address other than the account address;
•	account address has been changed within 15 days of the sell order; or
•	check is payable to a party other than the account shareholder(s), Principal Life or a retirement plan trustee or custodian that has
	agreed in writing to accept a transfer of assets from the Fund.
	* 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.
Sell shares in amounts of $100,000 or less by telephone
•	The combined amount requested from all funds to which the redemption request relates is $100,000 or less.
•	The address on the account must not have been changed within the last 15 days and telephone privileges must apply to the account
	from which the shares are being sold.
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).
The Fund from which the systematic withdrawal is made makes no recommendation as to either the number of shares or the fixed
amount that you withdraw.
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 below.
Distributions in Kind. Payment for shares of the Funds tendered for redemption is ordinarily made by check. However, the Funds 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, each of the Funds 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 a Fund pays the redemption proceeds in kind, the redeeming shareholder might
incur brokerage or other costs in selling the securities for cash. Each 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.
Exchange of Fund Shares
Class A, Class B and Class C Shares
Your shares in the Funds may be exchanged without a sales charge or CDSC for the same class of any other Principal Funds (except
Money Market). Effective May 12, 2010, exchanges cannot be made into the Acquired 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.
Automatic Exchange Election
This election authorizes an exchange from one fund of Principal Funds to another on a monthly, quarterly, semiannual or annual basis.
You can set up an automatic exchange by:
•	completing the Automatic Exchange Election section of the application,
•	calling us if telephone privileges apply to the account from which the exchange is to be made, or
•	sending us your written instructions.
•	completing an Automatic Exchange Election form (available on www.principalfunds.com)
Your automatic exchange continues until:
•	you instruct us to stop by calling us if telephone privileges apply to the account or by sending us your written instructions; or
•	your Fund account balance is zero.
You may specify the day of the exchange (if none is selected, the exchange will be made on the 15th of the month). If the selected day 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.

29

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).
	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 in
“Frequent Purchases and Redemptions.”
Institutional Class and Retirement Class 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 the 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 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 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.
Class J Shares
	Your shares in the Funds may be exchanged without a CDSC for the same share class of any other Principal Funds. However, the
original purchase date of the shares from which an exchange is made is used to determine if newly acquired shares are subject to a CDSC
when they are sold. The Fund reserves the to 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 55904
		Boston, MA 02205
	•	completing an Exchange Authorization Form (available on www.principalfunds.com or by calling 1-800-222-5852).
	•	via the Internet at www.principalfunds.com.
	•	calling us, if you have telephone privileges on the account.

Automatic Exchange Election
	This election authorizes an exchange from one Principal Funds to another on a monthly, quarterly, semiannual or annual basis. You can
set up an automatic exchange by:
	•	completing an automatic Exchange Election form available on www.principalfunds.com,
	•	completing the Automatic Exchange Election section of the application,
	•	calling us if telephone privileges apply to the account from which the exchange is to be made, or
	•	sending us your written instructions.
	Your automatic exchange continues until:
	•	you instruct us to stop by calling us if telephone privileges apply to the account or by sending us your written instructions; or
	•	your Fund account balance is zero.
	You may specify the day of the exchange (if none is selected, the exchange will be made on the 15th of the month). If the selected day 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.

	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 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.

The Board of Directors of the Fund has adopted policies and procedures with respect to frequent purchases and redemptions of shares of
the Funds. The Funds monitor shareholder 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 and their shareholders may be harmed. When we do
identify abusive trading, we will apply our policies and procedures in a fair and uniform manner.
Class A and Class C Shares
Currently the Funds impose an excessive trading fee on redemptions or exchanges of $30,000 or more of a Fund’s Class A, Class B and
Class 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 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.
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 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.
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,”
•	Limiting 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 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.
Institutional Class Shares
If we, or a 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 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. We will give you
notice in writing in this instance.
Retirement Class Shares
The Funds have adopted an exchange frequency restriction, described above in “Exchange of Fund Shares” to limit excessive trading in
fund shares.

32

Class J Shares
	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.
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 Funds pay their net investment
income on an annual basis. The payment date is annually in December.
	Net realized capital gains, if any, are distributed annually in 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 PFI Fund 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 1940 Act 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 Funds 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, 2011, 

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 a Fund by a shareholder, although in effect a return of capital to 

that shareholder, would be taxable to that shareholder as described above, subject to a holding period requirement for dividends designated as 

qualified dividend income. 

         Because of tax law requirements, you must provide the Funds 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 a 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 a 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. 

         The information contained in this Proxy Statement/Prospectus is not a complete description of the federal, state, local, or foreign tax 

consequences of investing in the Fund. You should consult your tax advisor before investing in the Fund. 

Portfolio Holdings Information

       A description of the PFI’s policies and procedures with respect to disclosure of the Funds’ portfolio securities is available in the 

Statement of Additional Information. 

VOTING INFORMATION

indicate or for approval of each matter for which there is no indication. You may revoke your proxy at any time prior to the proxy’s exercise 

by: (i) sending written notice to the Secretary of Principal Funds, Inc. at Principal Financial Group, Des Moines, Iowa 50392-2080, prior to 

the Meeting; (ii) subsequent execution and return of another proxy prior to the Meeting; or (iii) being present and voting in person at the 

Meeting after giving oral notice of the revocation to the Chairman of the Meeting. 

       Voting rights. Only shareholders of record at the close of business on April 26, 2010 (the “Record Date”), are entitled to vote. The 

shareholders of each class of shares of the Acquired Fund will vote together on the proposed Reorganization and on any other matter 

submitted to such shareholders. You are entitled to one vote on each matter submitted to the shareholders of the Acquired Fund for each 

share of the Fund that you hold, and fractional votes for fractional shares held. The Proposal requires for approval the affirmative vote of a 

“Majority of the Outstanding Voting Securities,” which is a term defined in the 1940 Act to mean, with respect to the Acquired Fund, the 

affirmative vote of the lesser of (1) 67% or more of the voting securities of the Fund present at the Meeting, 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. 

       The number of votes eligible to be cast at the Meeting as of the Record Date and other share ownership information are set forth below 

under the heading “Outstanding Shares and Share Ownership” in this Proxy Statement/Prospectus. 

       Quorum requirements. A quorum must be present at the Meeting for the transaction of business. The presence in person or by proxy of 

one-third of the shares of the Acquired Fund outstanding at the close of business on the Record Date constitutes a quorum for a meeting of 

that Fund. Abstentions and broker non-votes (proxies from brokers or nominees indicating that they have not received instructions from the 

beneficial owners on an item for which the broker or nominee does not have discretionary power) are counted toward a quorum but do not 

represent votes cast for any issue. Under the 1940 Act, the affirmative vote necessary to approve a proposal may be determined with 

reference to a percentage of votes present at the Meeting, which would have the effect of counting abstentions as if they were votes against a 

proposal. 

       In the event the necessary quorum to transact business or the vote required to approve a proposal is not obtained at the Meeting, the 

persons named as proxies or any shareholder present at the Meeting may propose one or more adjournments of the Meeting in accordance 

with applicable law to permit further solicitation of proxies. Any such adjournment as to the Proposal or any other matter will require the 

affirmative vote of the holders of a majority of the shares of the Acquired Fund cast at the Meeting. The persons named as proxies and any 

shareholder present at the Meeting will vote for or against any adjournment in their discretion. 

       Solicitation procedures. PFI intends to solicit proxies by mail. Officers or employees of PFI, PMC or their affiliates may make additional 

solicitations by telephone, internet, facsimile or personal contact. They will not be specially compensated for these services. Brokerage 

houses, banks and other fiduciaries may be requested to forward soliciting materials to their principals and to obtain authorization for the 

execution of proxies. For those services, they will be reimbursed by PMC for their out-of-pocket expenses. 

       Expenses of the Meeting. The expenses of the Meeting will be treated as an expense related to the Reorganization and will be paid by the 

Acquired Fund.

FINANCIAL HIGHLIGHTS

           The financial highlights table for each of the Acquired Fund and the Acquiring Fund is intended to help investors understand the 

financial performance of each Fund for the past five fiscal years (or since inception in the case of a Fund in operation for less than five years). 

Certain information reflects financial results for a single share of a Fund. The total returns in the tables represent the rate that an investor 

would have earned (or lost) on an investment in a particular Fund (assuming reinvestment of all dividends and distributions). Information for 

the fiscal years ended October 31, 2005, through October 31, 2009, has been audited by Ernst & Young LLP, Independent Registered Public 

Accounting Firm, whose report, along with each Fund’s financial statements, is included in PFI’s Annual Report to Shareholders for the 

fiscal year ended October 31, 2009. Copies of this report are available on request as described above.

Appendix A 

FORM OF PLAN OF ACQUISITION

LargeCap Blend Fund I and

LargeCap S&P 500 Index Fund

The Board of Directors of Principal Funds, Inc., a Maryland corporation (the “Fund”), deems it advisable that 

LargeCap S&P 500 Index Fund series of the Fund (“LargeCap S&P 500 Index”) acquire all of the assets of LargeCap Blend 

Fund I series of the Fund (“LargeCap Blend”) in exchange for the assumption by LargeCap S&P 500 Index of all of the 

liabilities of LargeCap Blend and shares issued by LargeCap S&P 500 Index which are thereafter to be distributed by 

LargeCap Blend pro rata to its shareholders in complete liquidation and termination of LargeCap Blend and in exchange for 

all of LargeCap Blend’s outstanding shares. 

LargeCap Blend will transfer to LargeCap S&P 500 Index, and LargeCap S&P 500 Index will acquire from 

LargeCap Blend, all of the assets of LargeCap Blend on the Closing Date and will assume from LargeCap Blend all of the 

liabilities of LargeCap Blend in exchange for the issuance of the number of shares of LargeCap S&P 500 Index determined 

as provided in the following paragraphs, which shares will be subsequently distributed pro rata to the shareholders of 

LargeCap Blend in complete liquidation and termination of LargeCap Blend and in exchange for all of LargeCap Blend’s 

outstanding shares. LargeCap Blend will not issue, sell or transfer any of its shares after the Closing Date, and only 

redemption requests received by LargeCap Blend in proper form prior to the Closing Date shall be fulfilled by LargeCap 

Blend. Redemption requests received by LargeCap Blend thereafter will be treated as requests for redemption of those shares 

of LargeCap S&P 500 Index allocable to the shareholder in question. 

LargeCap Blend will declare, and LargeCap S&P 500 Index may declare, to its shareholders of record on or prior to 

the Closing Date a dividend or dividends which, together with all previous such dividends, shall have the effect of 

distributing to its shareholders all of its income (computed without regard to any deduction for dividends paid) and all of its 

net realized capital gains, if any, as of the Closing Date. 

On the Closing Date, LargeCap S&P 500 Index will issue to LargeCap Blend a number of full and fractional shares 

of LargeCap S&P 500 Index, taken at their then net asset value, having an aggregate net asset value equal to the aggregate 

value of the net assets of LargeCap Blend. The aggregate value of the net assets of LargeCap Blend and LargeCap S&P 500 

Index shall be determined in accordance with the then current Prospectus of the Fund as of close of regularly scheduled 

trading on the New York Stock Exchange on the Closing Date. 

The closing of the transactions contemplated in this Plan (the “Closing”) shall be held at the offices of Principal 

Management Corporation, 680 8th Street, Des Moines, Iowa 50392 at 3:00 p.m. Central Time on July 23, 2010, or on such 

earlier or later date as fund management may determine. The date on which the Closing is to be held as provided in this Plan 

shall be known as the “Closing Date.” 

In the event that on the Closing Date (a) the New York Stock Exchange is closed for other than customary weekend 

and holiday closings or (b) trading on said Exchange is restricted or (c) an emergency exists as a result of which it is not 

reasonably practicable for LargeCap S&P 500 Index or LargeCap Blend to fairly determine the value of its assets, the 

Closing Date shall be postponed until the first business day after the day on which trading shall have been fully resumed. 

As soon as practicable after the Closing, LargeCap Blend shall (a) distribute on a pro rata basis to the shareholders 

of record of LargeCap Blend at the close of business on the Closing Date the shares of LargeCap S&P 500 Index received by 

LargeCap Blend at the Closing in exchange for all of LargeCap Blend’s outstanding shares (the holders of Class A, Class C, 

Class J, Class R-1, Class R-2, Class R-3, Class R-4, Class R-5 and the Institutional Class shares of LargeCap Blend will 

receive, respectively, Class A, Class C, Class J, Class R-1, Class R-2, Class R-3, Class R-4, Class R-5 and Institutional Class 

shares of LargeCap S&P 500 Index. The holders of Class B shares of LargeCap Blend will receive Class A shares of 

LargeCap S&P 500 Index), and (b) be liquidated in accordance with applicable law and the Fund’s Articles of Incorporation. 

For purposes of the distribution of shares of LargeCap S&P 500 Index to shareholders of LargeCap Blend, 

LargeCap S&P 500 Index shall credit its books an appropriate number of its shares to the account of each shareholder of 

LargeCap Blend. No certificates will be issued for shares of LargeCap S&P 500 Index. After the Closing Date and until 

surrendered, each outstanding certificate, if any, which, prior to the Closing Date, represented shares of LargeCap Blend, 

shall be deemed for all purposes of the Fund’s Articles of Incorporation and Bylaws to evidence the appropriate number of 

shares of LargeCap S&P 500 Index to be credited on the books of LargeCap S&P 500 Index in respect of such shares of 

LargeCap Blend as provided above. 

Prior to the Closing Date, LargeCap Blend shall deliver to LargeCap S&P 500 Index a list setting forth the assets to 

be assigned, delivered and transferred to LargeCap S&P 500 Index, including the securities then owned by LargeCap Blend 

and the respective federal income tax bases (on an identified cost basis) thereof, and the liabilities to be assumed by 

LargeCap S&P 500 Index pursuant to this Plan. 

All of LargeCap Blend’s portfolio securities shall be delivered by LargeCap Blend’s custodian on the Closing Date 

to LargeCap S&P 500 Index or its custodian, either endorsed in proper form for transfer in such condition as to constitute 

good delivery thereof in accordance with the practice of brokers or, if such securities are held in a securities depository within 

the meaning of Rule 17f-4 under the Investment Company Act of 1940, transferred to an Fund in the name of LargeCap S&P 

500 Index or its custodian with said depository. All cash to be delivered pursuant to this Plan shall be transferred from 

LargeCap Blend’s Fund at its custodian to LargeCap S&P 500 Index’ Fund at its custodian. If on the Closing Date LargeCap 

Blend is unable to make good delivery to LargeCap S&P 500 Index’ custodian of any of LargeCap Blend’s portfolio 

securities because such securities have not yet been delivered to LargeCap Blend’s custodian by its brokers or by the transfer 

agent for such securities, then the delivery requirement with respect to such securities shall be waived, and LargeCap Blend 

shall deliver to LargeCap S&P 500 Index’ custodian on or by said Closing Date with respect to said undelivered securities 

executed copies of an agreement of assignment in a form satisfactory to LargeCap S&P 500 Index, and a due bill or due bills 

in form and substance satisfactory to the custodian, together with such other documents including brokers’ confirmations, as 

may be reasonably required by LargeCap S&P 500 Index. 

This Plan may be abandoned and terminated, whether before or after action thereon by the shareholders of LargeCap 

Blend and notwithstanding favorable action by such shareholders, if the Board of Directors believe that the consummation of 

the transactions contemplated hereunder would not be in the best interests of the shareholders of either Fund. This Plan may 

be amended by the Board of Directors at any time, except that after approval by the shareholders of LargeCap Blend no 

amendment may be made with respect to the Plan which in the opinion of the Board of Directors materially adversely affects 

the interests of the shareholders of LargeCap Blend. 

Except as expressly provided otherwise in this Plan, LargeCap Blend will pay or cause to be paid all out-of-pocket 

fees and expenses incurred in connection with the transaction contemplated under this Plan, including, but not limited to, 

accountant’s fees, legal fees, and proxy related costs. 

IN WITNESS WHEREOF, each of the parties hereto has caused this Plan to be executed by its President and Chief Executive 

Officer or its Executive Vice President as of the ^th day of __________, 2010.

Pro Forma Notes to Financial Statements 

October 31, 2009

(unaudited)

1. Description of the Funds

LargeCap Blend Fund I and LargeCap S&P 500 Index Fund are series of Principal Funds, Inc. (the “Fund”). The Fund is registered under the Investment Company Act of 1940, as amended, as an open-end management investment company.

2. Basis of Combination

On March 8, 2010, the Board of Directors of Principal Funds, Inc., LargeCap Blend Fund I approved an Agreement and Plan of Reorganization (the “Reorganization”) whereby, LargeCap S&P 500 Index Fund will acquire all the assets of LargeCap Blend Fund I subject to the liabilities of such fund, in exchange for a number of shares equal to the pro rata net assets of LargeCap S&P 500 Index Fund.

The Reorganization will be accounted for as a tax-free reorganization of investment companies. The pro forma combined financial statements are presented for the information of the reader and may not necessarily be representative of what the actual combined financial statements would have been had the Reorganization occurred at October 31, 2009. The unaudited pro forma schedules of investments and statements of assets and liabilities reflect the financial position of LargeCap Blend Fund I and LargeCap S&P 500 Index Fund at October 31, 2009. The unaudited pro forma statements of operations reflect the results of operations of LargeCap Blend Fund I and LargeCap S&P 500 Index Fund for the twelve months ended October 31, 2009. The statements have been derived from the Funds’ respective books and records utilized in calculating daily net asset value at the dates indicated above for LargeCap Blend Fund I and LargeCap S&P 500 Index Fund under U.S. generally accepted Funding principles. The historical cost of investment securities will be carried forward to the surviving entity and results of operations of LargeCap S&P 500 Index Fund for pre-combination periods will not be restated.

LargeCap Blend Fund I will pay all expenses and out-of-pocket fees incurred in connection with the Reorganization, including printing, mailing, and legal fees. These expenses and fees are expected to total $104,900. LargeCap Blend Fund I will pay any trading costs associated with disposing of any portfolio securities that would not be compatible with the investment objectives and strategies of the LargeCap S&P 500 Index Fund and reinvesting the proceeds in securities that would be compatible. The trading costs are estimated to be $397,000 with an approximate gain of $5,427,000 on a U.S. GAAP basis. The estimated per share capital gain would be $0.04.

The pro forma schedules of investments and statements of assets and liabilities and operations should be read in conjunction with the historical financial statements of the Funds incorporated by reference in the Statements of Additional Information.

3. Significant Funding Policies

The preparation of financial statements in conformity with U.S. generally accepted Funding principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

4. Security Valuation

LargeCap Blend Fund I and LargeCap S&P 500 Index Fund value securities for which market quotations are readily available at market value, which is determined using the last reported sale price. If no sales are reported, as is regularly the case for some securities traded over-the-counter, securities are valued using the last reported bid price or an evaluated bid price provided by a pricing service. Pricing services use electronic modeling techniques that incorporate security characteristics, market conditions and dealer-supplied valuations to determine an evaluated bid price. When reliable market quotations are not considered to be readily available, which may be the case, for example, with respect to restricted securities, certain debt securities, preferred stocks, and foreign securities, the investments are valued at their fair value as determined in good faith by Principal Management Corporation (the “Manager”) under procedures established and periodically reviewed by the Fund’s Board of Directors.

The value of foreign securities used in computing the net asset value per share is generally determined as of the close of the foreign exchange where the security is principally traded. Events that occur after the close of the applicable foreign market or exchange but prior to the calculation of the Fund’s net asset value are ordinarily not reflected in the Fund’s net asset value. If the Manager reasonably believes events that occur after the close of the applicable foreign market or exchange but prior to the calculation of the Fund’s net asset value will materially affect the value of a foreign security, then the security is valued at its fair value as determined in good faith by the Manager under procedures established and periodically reviewed by the Fund’s Board of Directors. Many factors are reviewed in the course of making a good faith determination of a security’s fair value, including, but not limited to, price movements in ADRs, futures contracts, industry indices, general indices and foreign currencies.

4. Security Valuation (Continued)

To the extent each Fund invests in foreign securities listed on foreign exchanges which trade on days on which the Fund does not determine its net asset value, for example weekends and other customary national U.S. holidays, each Fund’s net asset value could be significantly affected on days when shareholders cannot purchase or redeem shares.

Certain securities issued by companies in emerging market countries may have more than one quoted valuation at any given 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 such oversight by the Fund’s Board of Directors as may occasionally be necessary.

Short-term securities purchased with less than 60 days until maturity are valued at amortized cost, which approximates market. Under the amortized cost method, a security is valued by applying a constant yield to maturity of the difference between the principal amount due at maturity and the cost of the security to the account.

In September 2006, the Financial Funding Standards Board (FASB) issued Statement of Financial Funding Standards No. 157, “Fair Value Measurements” (FAS 157). This standard clarifies the definition of fair value for financial reporting, establishes a framework for measuring fair value and requires additional disclosures about the use of fair value measurements. Effective November 1, 2008, the Funds adopted the provisions of FAS 157.

In accordance with FAS 157, fair value is defined as the price that the Funds would receive upon selling a security in a timely transaction to an independent buyer in the principal or most advantageous market of the security at the measurement date. In determining fair value, the Funds use various valuation approaches, including market, income and/or cost approaches. FAS 157 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available.

Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Funds. Unobservable inputs are inputs that reflect the Funds own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.

The three-tier hierarchy of inputs is summarized in the three broad levels listed below.

-- Level 1 – Quoted prices are available in active markets for identical securities as of the reporting date. The type of securities included in Level 1 includes listed equities and listed derivatives.

-- Level 2 – Other significant observable inputs (including quoted prices for similar investments, interest rates, prepayments speeds, credit risk, etc.) Investments which are generally included in this category include corporate bonds, senior floating rate interests, and municipal bonds.

-- Level 3 – Significant unobservable inputs (including the Funds’ assumptions in determining the fair value of investments.) Investments which are generally included in this category include certain corporate bonds and certain mortgage backed securities.

The availability of observable inputs can vary from security to security and is affected by a wide variety of factors, including, for example, the type of security, whether the security is new and not yet established in the market place, and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Funds in determining fair value is greatest for instruments categorized in Level 3.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes the level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety.

Fair value is a market based measure considered from the perspective of a market participant who holds the asset rather than an entity specific measure. Therefore, even when market assumptions are not readily available, the Fund’s own assumptions are set to reflect those that market participants would use in pricing the asset or liability at the measurement date. The Funds use prices and inputs that are current as of the measurement date.

4. Security Valuation (Continued)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those instruments. Generally, amortized cost approximates the current fair value of these securities, but because the value is not obtained from a quoted price in an active market, such securities are reflected as Level 2.

The following is a summary of the inputs used as of October 31, 2009 in valuing the Funds’ securities carried at value (amounts shown in thousands):

			Level 2 - Other
			Significant
		Level 1 -	Observable	Level 3 - Significant	Totals
Fund		Quoted Prices	Inputs	Unobservable Inputs	(Level 1,2,3)
LargeCap Common Blend Stock Fund(a) I		$ 870,946	$ —	$ —	$ 870,946
Repurchase Agreements		—	25,217	—	25,217
	Total investments in securities	$ 870,946	$ 25,217	$ —	$ 896,163
Futures(b)		$ (625)	$ —	$ —	$ (625)
LargeCap S&P 500 Index Fund
Common Stock(a)		$ 884,631	$ —	$ —	$ 884,631
Repurchase Agreements		—	27,449	—	27,449
	Total investments in securities	$ 884,631	$ 27,449	$ —	$ 912,080
Futures(b)		$ (616)	$ —	$ —	$ (616)

^(a) For additional detail regarding sector classifications, please see the Schedule of Investments.

^(b) Futures, foreign currency contracts, written options and swap agreements are valued at the unrealized appreciation/(depreciation) of the instrument.

5. Futures Contracts

The Funds are subject to equity price risk, interest rate risk, and foreign currency exchange rate risk in the normal course of pursuing their investment objectives. The Funds may enter into futures contracts to hedge against changes in or to gain exposure to, change in the value of equities, interest rates and foreign currencies. Initial margin deposits are made by cash deposits or segregation of specific securities as may be required by the exchange on which the transaction was conducted. Pursuant to the contracts, a fund agrees to receive from or pay to the broker, an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments are known as “variation margin” and are recorded by the fund as a variation margin receivable or payable on futures contracts. During the period the futures contracts are open, daily changes in the value of the contracts are recognized as unrealized gains or losses. These unrealized gains or losses are included as a component of net unrealized appreciation (depreciation) of investments on the statements of assets and liabilities. When the contracts are closed, the Fund recognizes a realized gain or loss equal to the difference between the proceeds from, or cost of, the closing transaction and the fund’s cost basis in the contract. There is minimal counterparty credit risk to the Funds because futures are exchange traded and the exchange’s clearinghouse, as counterparty to all exchange traded futures, guarantees the futures against default.

6. Repurchase Agreements

The Funds may invest in repurchase agreements that are fully collateralized, typically by U.S. government or U.S. government agency securities. It is the Funds’ policy that its custodian takes possession of the underlying collateral securities. The fair value of the collateral is at all times at least equal to the total amount of the repurchase obligation. In the event of default on the obligation to repurchase, the Funds have the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. In the event the seller of a repurchase agreement defaults, the Funds could experience delays in the realization of the collateral.

7. Capital Shares

The pro forma net asset value per share assumes issuance of shares of LargeCap S&P 500 Index Fund that would have been issued at October 31, 2009, in connection with the Reorganization. The number of shares assumed to be issued is equal to the net assets of LargeCap Blend Fund I, as of October 31, 2009, divided by the net asset value per share of the LargeCap S&P 500 Index Fund as of October 31, 2009. The pro forma number of shares outstanding, by class, for the combined fund can be found on the statement of assets and liabilities.

8. Pro Forma Adjustments

The accompanying pro forma financial statements reflect changes in fund shares as if the Reorganization had taken place on October 31, 2009. The expenses of the LargeCap Blend Fund I were adjusted assuming the fee structure of the LargeCap S&P 500 Index Fund was in effect for the twelve months ended October 31, 2009.

9. Distributions

No provision for federal income taxes is considered necessary because each fund is qualified as a “regulated investment company” under the Internal Revenue Code and intends to distribute each year substantially all of its net investment income and realized capital gains to shareholders.
