The SAM Portfolios offer long-term investors different asset allocation strategies having different levels of potential investment risk and reward. The Portfolio is intended to offer the potential for a medium level of income and capital growth, with exposure to a medium level of principal risk. The SAM Portfolios operate as funds of funds and invest principally in Institutional Class shares of Principal Funds, Inc. equity funds, fixed-income funds and specialty funds ("Underlying Funds"); the Sub-Advisor generally categorizes the Underlying Fund based on the investment profile of the Underlying Fund. Each SAM Portfolio typically allocates its assets among Underlying Funds, and within predetermined percentage ranges, as determined by the Sub-Advisor in accordance with its outlook for the economy, the financial markets and the relative market valuations of the Underlying Funds. The Portfolio: Generally invests between 20% and 60% of its assets in fixed-income funds, &#x2022; and less than 40% in any one fixed- income fund Generally invests between 40% and 80% of its assets in equity funds, and less &#x2022; than 30% in any one equity fund Generally invests less than 20% of its assets in specialty funds, and less &#x2022; than 20% in any one specialty fund The Portfolio may temporarily exceed the applicable percentage ranges for short periods, and the Sub-Advisor may alter the percentage ranges when it deems appropriate. </pre>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

However, the Portfolio is subject to the particular risks of the Underlying Funds in which it invests, and its share prices and performance will fluctuate with the shares prices and performance of the Underlying Funds. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. If you sell your shares when their value is less than the price you paid, you will lose money. The SAM Portfolios share the same risks but often with different levels of exposure. The Portfolio has greater exposure than the Flexible Income and Conservative Balanced Portfolios to (in alphabetical order): Equity Securities Risk. Equity securities (common, convertible preferred stocks and other 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. Foreign Securities Risk. The risks of foreign securities include loss of value as a result of: political or economic instability; nationalization, expropriation or confiscatory taxation; changes in foreign exchange rates and foreign exchange restrictions; settlement delays; and limited government regulation (including less stringent reporting, accounting, and disclosure standards than are required of U.S. companies). Certain of these risks are greater for investments in emerging markets. The Portfolio has less exposure than the Flexible Income and Conservative Balanced Portfolio to (in alphabetical order): Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit quality risk. The market value of fixed-income securities generally declines when interest rates rise, and an issuer of fixed-income securities could default on its payment obligations. High Yield Securities Risk. High yield fixed-income securities (commonly referred to as "junk bonds") are subject to greater credit quality risk than higher rated fixed-income securities and should be considered speculative. Portfolio Duration Risk. Portfolio duration is a measure of the expected life of a fixed-income security and its sensitivity to changes in interest rates. The longer a fund's average portfolio duration, the more sensitive the fund will be to changes in interest rates. Preferred Securities Risk. Preferred securities are junior subordinated securities in a company's capital structure and therefore can be subject to greater credit and liquidation risk. Prepayment Risk. Unscheduled prepayments on mortgage-backed and asset-backed securities may have to be reinvested at lower rates. A reduction in prepayments may increase the effective maturities of these securities, exposing them to the risk of decline in market value over time (extension risk). U.S. Government Securities Risk. Yields available from U.S. government securities are generally lower than yields from many other fixed-income securities. U.S. Government Sponsored Securities Risk. Securities issued by U.S. government-sponsored or -chartered enterprises such as the Federal Home Loan Mortgage Corporation, the Federal National Mortgage Association, and the Federal Home Loan Banks are not issued or guaranteed by the U.S. Treasury. Each of the SAM Portfolios is subject directly or indirectly through the underlying funds to (in alphabetical order): Asset Allocation Risk. A fund's selection and weighting of asset classes and/or underlying funds may cause it to underperform other funds with a similar investment objective. Conflict of Interest Risk. The Advisor and its affiliates earn different fees from different underlying funds and may have an incentive to allocate more fund-of-fund assets to underlying funds from which they receive higher fees. Investment Company Securities Risk. Fund shareholders bear indirectly their proportionate share of the expenses of other investment companies in which the Fund invests. Underlying Fund Risk. As of the date of this prospectus, this fund was being used as an underlying fund of a fund of funds, and an underlying fund of 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.</pre>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

If the Fund provides this disclosure, also disclose the period for which the expense reimbursement or fee waiver arrangement is expected to continue, and briefly describe who can terminate the arrangement and under what circumstances.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Paragraph 1 -Subparagraph 11 -Subsection table falsefalseExpense Reimbursement130false0rr_NetExpensesOverAssetsrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.02160.0216falsefalsefalsefalsefalseOtherrr:NonNegativePure4TypepureTotal Annual Fund Operating Expenses.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Paragraph 1 -Subparagraph 11 -Subsection table falsefalseTotal Annual Fund Operating Expenses after Expense Reimbursement131false0rr_ExpenseExampleYear01rrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue719719falsefalsefalsefalsefalseMonetaryrr:NonNegativeMonetaryTypemonetaryThe Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.
