See the fact sheet for the full name of the Separate Account. Certain investment options may not be available in all states or U.S. commonwealths. Principal Life Insurance Company reserves the right to defer payments or transfers from Principal Life Separate Accounts as described in the group annuity contracts providing access to the Separate Accounts or as required by applicable law. Such deferment will be based on factors that may include situations such as: unstable or disorderly financial markets; investment conditions which do not allow for orderly investment transactions; or investment, liquidity, and other risks inherent in real estate (such as those associated with general and local economic conditions). If you elect to allocate funds to a Separate Account, you may not be able to immediately withdraw them. A mutual fund's share price and investment return will vary with market conditions, and the principal value of an investment when you sell your shares may be more or less than the original cost. Insurance products and plan administrative services, if applicable, are provided by Principal Life Insurance Company. Securities are offered through Principal Securities, Inc., 1.800.547.7754, member SIPC and/or independent broker/dealers.

Investors should carefully consider a mutual fund s investment objectives, risks, charges, and expenses prior to investing.

Shares or unit values will fluctuate and investments, when redeemed, may be worth more or less than their original cost. This does not apply, however, to the guaranteed portions of group annuity contracts issued by Principal Life that constitute guaranteed benefit policies as defined in ERISA 401(b)(2)(B). This report includes investment options that contain information from a variety of sources. A primary source is Morningstar which provides holdings information, operations data, and rankings or statistics proprietary to Morningstar.

Small-cap and mid-cap investment options are subject to more fluctuation in value and may have additional risks than other investment options with stocks of larger, more stable companies. 2. Each index based investment option is invested in the stocks or bonds of the index it tracks. Performance of indexes reflects the unmanaged results for the market segment the selected stocks or bonds represent. There is no assurance an index based investment option will match the performance of the index tracked. 3. This Separate Account invests solely in the least expensive share class of the Principal Funds. All voting rights associated with ownership of shares in the mutual fund are the rights of the Separate Account, not of contract holders investing in the Separate Account. For further information on the underlying mutual fund, see the prospectus of the fund. 4. International and global investment options are subject to additional risk due to fluctuating exchange rates, foreign accounting and financial policies, and other economic and political environments. 6.

For time periods prior to inception date of the fund, predecessor performance is reflected. Please see the fund's prospectus for more information on specific expenses, and the fund's most recent shareholder report for actual date of first sale. Expenses are deducted from income earned by the fund. As a result, dividends and investment results will differ for each share class. 11. Principal Fixed Income Guaranteed Option is the Group Annuity Contract - Custodial Guaranteed Interest Contract available through Principal Life Insurance Company, a member of the Principal Financial Group, Des Moines Iowa 50392. May not be available in all states. 12. Equity investment options involve greater risk, including heightened volatility, than fixed-income investment options.

Important Information ASSOCIATION+OF+CHAMBER+OF+COMMERCE+EXECUTIVES+PROFIT+SHARING+PLAN Contract #6-14541 13. Asset allocation does not guarantee a profit or protect against a loss. Investing in real estate, small-cap, international, and high-yield investment options involves additional risks. 15. Fixed-income investment options are subject to interest rate risk, and their value will decline as interest rates rise. Neither the principal of bond investment options nor their yields are guaranteed by the U.S. government. 16. If the retirement program provides a participant access to the Fixed Income Guaranteed Option and Competing Plan Investment Options, participant transfers, either directly or indirectly, to Competing Plan Investment Options will generally be subject to an Equity Wash. An Equity Wash requires that transfers must be directed to a non-competing investment option under the plan for 90-days before such transferred amounts may be directed to any other Competing Plan Investment Option. Competing Plan Investment Options include other guaranteed investment options, or fixed income, money market, or bond funds that have ever had an average duration of 3.0 years or less. 17. The Fixed Income Guaranteed Option is a guarantee backed by the general account of Principal Life Insurance Company(Principal Life). As a guarantee, it does not have an investment management fee or expense ratio; those are concepts unique to investment products. The Rate Level Service Fee illustrated here represents the part of the overall fee arrangement that the plan pays for services from Principal Life as a provider of administrative services to the plan, as agreed to in the Service and Expense Agreement for the plan. 18. The crediting rate shown for the Fixed Income Guaranteed Option is an effective annual rate and is displayed here as the rate guaranteed by Principal Life net of the fees for administrative services to the plan illustrated in the Rate Level Service Fee column for the Fixed Income Guaranteed Option. 23. Fixed-income and asset allocation investment options that invest in mortgage securities are subject to increased risk due to real estate exposure. 26. This Separate Account invests solely in the least expensive share class of a mutual fund (Fund) from Principal Funds, Inc. The investment manager of the Fund, Principal Global Investors, invests between 10% and 40% of the Fund's assets in common stocks in an attempt to match or exceed the performance of the Fund's benchmark index for performance. 27. Asset allocation and diversification do not ensure a profit or protect against a loss. Additionally there is no guarantee this investment option will provide adequate income at or through retirement. 28. The Investment Advisor will display "Multiple Sub-Advisors" for certain target-date, target-risk and specialty investment options where the assets are directed by the Investment Manager to multiple underlying investment options. These underlying investment options may use multiple sub-advisors who are responsible for the day-to-day management responsibilities. 29. This investment option is subject to investment and liquidity risk and other risks inherent in real estate such as those associated with general and local economic conditions. If you elect to contribute funds into the U.S. Property Separate Account, withdrawals may be delayed for up to 3 years. Page 46

For Mutual Fund Network investment options, returns for all time periods, except the Since Inception time frame, may include the historical performance of the oldest share class of the fund, adjusted to reflect a portion of the fees and expenses of this share class. Since Inception returns display the actual return of this share class and do not reflect the adjusted returns of the oldest share class. Please see the fund's prospectus for more information on specific expenses, and the fund's most recent shareholder report for actual date of first sale. Expenses are deducted from income earned by the fund. As a result, dividends and investment results will differ for each share class. 31. The risks associated with derivative investments include that the underlying security, interest rate, market index, or other financial asset will not move in the direction the Investment Adviser and/or Sub-Advisor anticipated, the possibility that there may be no liquid secondary market, the risk that adverse price movements in an instrument can result in a loss substantially greater than a fund's initial investment, the possibility that the counterparty may fail to perform its obligations; and the inability to close out certain hedged positions to avoid adverse tax consequences. 32.

The Adviser or other affiliates of the Trust Company may provide services to the CITs and may receive fees for such services. The CITs are available only to certain qualified retirement plans and governmental 457(b) plans. 37. The CITs are not mutual funds and are not registered with the Securities and Exchange Commission, the State of Oregon, or any other regulatory body. Units of the CITs are not deposits or obligations of, guaranteed by, or insured by the Trust Company or any affiliate, and are not insured by the FDIC or any other federal or state government agency. The value of the CITs will fluctuate so that when redeemed, units may be worth more or less than the original cost. The declaration of trust, participation agreement, and disclosure documents contain important information about investment objectives, risks, fees and expenses associated with investment in the CITs and should be read carefully before investing. The declaration of trust is available at principal.com. A copy of the participation agreement can be obtained from your plan administrator. Page 47
