The MMBB Money Market Fund seeks stability of returns and capital preservation. There is no guarantee that these objectives will be met.

The Money Market Fund invests in a broadly diversified portfolio of high-quality, investment grade, short-term money market securities. This fund typically holds bank deposits, certificates of deposit, U.S. Treasury bulls, repurchase agreements and asset-backed securities, domestic and dollar-denominated foreign commercial paper, and other short-term corporate obligations, including those with floating or variable rates of interest. The average maturity of the fund's holdings tends to be 90 days or less. The net return will be the result of general money market performance, plus or minus the manager's active performance, less investment and administration expenses.

Opportunities

The Money Market Fund is one of the most conservative of MMBB's investment options. There is very little risk of loss of your original investment, over either the short term or the long term. Note, however, that "little risk" does not mean "no risk." See the Risk section below.

There is a high probability that returns will be consistently positive. The net return will be the result of short-term interest rates less investment and administration expenses.

Risks

All securities investments risk the loss of capital.

This fund is unlikely to provide meaningful long-term growth of capital.

Although there is a high probability of returns being consistently positive, over time returns are likely to be considerably less than other investment options.

The return of this fund may not keep pace with inflation eroding purchasing power of the original investment.

In a declining interest rate environment income from this fund will be reduced. It is possible that the fund can experience negative returns as a result of 1) interest income being insufficient to offset expenses of the fund, and/or 2) the downgrading of credit-type investments such as corporate bonds, and/or 3) the inability of issuers to meet the obligations of the short-term securities that they have issued.

One of the Money Market Fund's primary risks is an extremely low interest rate. In 2009 and 2010, for example, short-term interest rates were nearly zero. During this time period fund expenses outweighed investment return and the fund actually experienced slightly negative net performance. In response, MMBB voluntarily waived its 50 basis point (0.50%) administrative charge. Had MMBB not waived the administrative fee, performance would have been less than reported below. There is a risk that should a similarly low interest rate environment occur in the future MMBB might not elect to waive its fee. In such a case, expenses could outweigh income, resulting in a member's account value declining.

If you are uncomfortable with the risks associated with the Money Market Fund, you may want to consider another MMBB investment option.

Fund Performance

To offer historical perspective on the long-term risk and return of this investment option in comparison to MMBB's other investment options, see the diagram below. It summarizes risk and return for more than ten years, and encompasses both rising and falling stock market periods as well as both economic expansions and recessions.

• The horizontal placement of the fund indicates the volatility of the investment option, one measure of risk. Volatility of returns can be mathematically measured and attracts a lot of attention among investors because the higher the volatility the more the value of your investment tends to rise and fall. If you decide to exit the investment when it is declining, the value of your investment may be less than you expected. The further to the right, the more the value of the fund is likely to fluctuate; the further to the left, the more stable, or reliable, the return of the option, historically.
• The vertical placement of the fund indicates the average return the investment option generated over the last 10+ years. The higher up on the diagram, the greater the return, the lower down, the more modest the return, on average, per year.

In reading this graph, please note the following:

• The data in the chart is periodically updated. As a result, the plot points may change.
• Past experience is no guarantee of future returns. This chart is just one tool to assist you in comparing one option to another.
• Returns can be negative as well as positive, especially in the short term.

While it is valuable to view investment performance over long-term time horizons, looking at shorter time periods can give one insight as to how returns may fluctuate from over shorter time periods. The table below displays calendar year returns.

From time to time MMBB contracts with one or more external managers to execute the stated strategy for the Money Market Fund. Recently the roster for this investment option included:

Dreyfus

For 2010 total expenses are estimated at 0.20%. Returns shown are net of all expenses. Expenses would be higher had MMBB not waived its 50 basis points (0.50%) administrative charge in response to the extremely low interest rate environment.
