Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before fee waivers and/or expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement arrangements will remain in place for the duration noted in the table above, but that there will be no fee waiver or expense reimbursement arrangements in effect thereafter. The example does not reflect the fees and expenses of any variable annuity contract or variable life insurance policy and the costs in the example would be higher if they did. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example	Money Market Fund Money Market Fund USD ($)
1 year	$ 15
3 years	73
5 years	135
10 years	$ 320

Principal investment strategies

The Fund is a “government money market fund,” as defined in the applicable rules governing money market funds, and as such invests at least 99.5% of its total assets in cash, U.S. Government securities and/or repurchase agreements that are collateralized fully by cash or U.S. Government securities. These investments include (1) securities issued by, or whose principal and interest are guaranteed by, the U.S. Government or one of its agencies or instrumentalities and (2) repurchase agreements involving securities issued or guaranteed by the U.S. Government or one of its agencies or instrumentalities. Short-term, U.S. Government securities generally pay interest that is among the lowest for income-paying securities. Because of this, the yield on the Fund will likely be lower than the yields on funds that invest in longer-term or lower-quality securities.

Generally, the Fund seeks to maintain a share value of $1.00 per share. The Fund’s investments will be made in accordance with the applicable rules governing the quality, maturity and diversification of securities and other instruments held by money market funds. The Fund maintains a dollar-weighted average maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less, and invests in debt obligations with a remaining maturity of 397 days or less.

Advisors limits the Fund’s investments to U.S. Government securities or securities that present minimal credit risks to the Fund and are of eligible quality.

A government money market fund is not required to impose liquidity fees or redemption gates, and the Fund does not currently intend to impose such fees and/or gates. However, the Fund’s Board of Trustees could elect to subject the Fund to such fees and/or gates in the future.

The above list of investments is not exclusive and the Fund may make other investments consistent with its investment objective and policies.

Principal investment risks

You could lose money over short or long periods by investing in this Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund’s sponsor has no legal obligation to provide support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time. An investment in the Fund, due to the nature of the Fund’s portfolio holdings, typically is subject to the following principal investment risks:

· Current Income Risk—The risk that the income the Fund receives may fall as a result of a decline in interest rates. In a low or negative interest rate environment, the Fund may not be able to achieve a positive or zero yield or maintain a stable net asset value (“NAV”) of $1.00 per share.

· Issuer Risk (often called Financial Risk)—The risk that an issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of the issuer’s financial instruments over short or extended periods of time.

· Credit Risk (a type of Issuer Risk)—The risk that the issuer of fixed-income investments may not be able or willing to meet interest or principal payments when the payments become due.

· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for the Fund to properly value its investments and that the Fund may not be able to purchase or sell an investment at an attractive price, if at all.

· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments may decline in certain interest rate environments.

· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments and during periods when prevailing interest rates are low or negative. As of the date of this Prospectus, interest rates in the United States and in certain foreign markets are at or near historic lows, which may increase the Fund’s exposure to risks associated with rising interest rates. In general, changing interest rates could have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.

· U.S. Government Securities Risk—Securities issued by the U.S. Government or one of its agencies or instrumentalities may receive varying levels of support from the U.S. Government, which could affect the Fund’s ability to recover should they default. To the extent the Fund invests significantly in securities issued or guaranteed by the U.S. Government or its agencies or instrumentalities, any market movements, regulatory changes or changes in political or economic conditions that affect the securities of the U.S. Government or its agencies or instrumentalities in which the Fund invests may have a significant impact on the Fund’s performance.

· Floating and Variable Rate Securities Risk—Floating and variable rate securities provide for a periodic adjustment in the interest rate paid on the securities. The rate adjustment intervals may be regular and range from daily up to annually, or may be based on an event, such as a change in the prime rate. Floating and variable rate securities may be subject to greater liquidity risk than other debt securities, meaning that there may be limitations on the Fund’s ability to sell the securities at any given time. Such securities also may lose value.

· Active Management Risk—The risk that Advisors’ strategy, investment selection or trading execution may cause the Fund to underperform relative to the peer group average or mutual funds with similar investment objectives.

Please see the non-summary portion of the Prospectus for more detailed information about the risks described above.

Past performance

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of shares of the Fund during the preceding ten-year period. Below the bar chart are the best and worst returns for a calendar quarter during the same period. The performance table following the bar chart shows the Fund’s average annual total returns over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2017, and how those returns compare to those of the Fund’s peer group average. Returns do not reflect fees and expenses of any variable annuity or variable life insurance contract and would be lower if they did.

The returns shown below reflect previous agreements by Advisors to waive or reimburse the Fund for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. As of October 14, 2016, certain changes were made to the Fund’s investment strategies. Performance information prior to this date reflects the Fund’s investment strategies before this date. As a result, the Fund’s performance after October 14, 2016 may differ materially from the performance information shown below for the period prior to October 14, 2016. Past performance of the Fund is not necessarily an indication of how it will perform in the future. The peer group average listed below is unmanaged, and you cannot invest directly in the peer group average.
