The percentage of the Fund&#8217;s assets invested in a given stock is approximately the same as the percentage such stock represents in the S&#038;P 500^&#174; Index. The Master Portfolio is managed by determining which securities are to be purchased or sold to reflect, to the extent feasible, the investment characteristics of its benchmark index. Under normal circumstances, at least 90% of the value of the Master Portfolio&#8217;s assets, plus the amount of any borrowing for investment purposes, is invested in securities comprising the S&#038;P 500^&#174; Index.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

An investment in the Fund is not a deposit or obligation of any bank, is not endorsed or guaranteed by any bank and is not insured by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. You may lose money by investing in the Fund. Below are all of the principal risks of investing in the Fund.</p><p><b>Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities fluctuates based on changes in a company&#8217;s financial condition and overall market and economic conditions.</p><p><b>Index Fund Risk:</b> An index fund has operating and other expenses while an index does not. As a result, while the Fund will attempt to track the S&#038;P 500^&#174; Index as closely as possible, it will tend to underperform the index to some degree over time.</p><p><b>Index Investing: </b>The Fund attempts to track the performance of the S&#038;P 500^&#174; Index. Therefore, securities may be purchased, retained and sold by the Fund at times when an actively managed fund would not do so. If the value of securities that are heavily weighted in the index changes, you can expect a greater risk of loss than would be the case if the Fund were not fully invested in such securities. The Fund reserves the right to concentrate its investments with respect to investments in any industry in which the S&#038;P 500^&#174; Index becomes concentrated to the same degree during the same period. To the extent the Fund concentrates in a particular industry, it may be more susceptible to economic conditions and risks affecting that industry. Imperfect correlation between the Fund's portfolio securities and those in the S&#038;P 500&#174; Index, Fund fees and expenses, maintenance of cash balances to meet redemption requests, rounding of prices and changes to an index and regulatory policies may cause tracking error, which is the divergence of the Fund's performance from that of the Fund's benchmark index.</p><p><b> Investment Style Risk:</b> The possibility that the market segment on which this Fund focuses &#8212; stocks in the S&#038;P 500^&#174; Index &#8212; will underperform other kinds of investments or market averages.</p><p><b>Investment Company Risk:</b> Investing in the Master Portfolio subjects the Fund to the Master Portfolio&#8217;s risks, including the risk that the Master Portfolio will not perform as expected. As a shareholder in the Master Portfolio, the Fund, and indirectly the Fund&#8217;s shareholders, bear a ratable share of the Master Portfolio&#8217;s expenses, with the result that the Fund&#8217;s expenses may be higher than those of other mutual funds that invest directly in securities.</p><p><b>Selection Risk:</b> Selection risk is the risk that the securities selected by fund management will underperform the markets, the relevant indices or the securities selected by other funds with similar investment objectives and investment strategies. This means you may lose money.</p><p><b>Market Risk: </b>The possibility that the Fund's stock holdings will decline in price because of a broad stock market decline. Markets generally move in cycles, with periods of rising prices followed by periods of falling prices. The value of your investment will tend to increase or decrease in response to these movements.</p><p>For more information about the Fund's risks, please see the Fund's prospectus or Statement of Additional Information (&#8220;SAI&#8221;). </p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also shouldshow the returns of an appropriate broadbased securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Paragraph 2 -Subparagraph iv -Subsection b falsefalsePerformance Table Narrative1The Shareholder Fees and Annual Fund Operating Expenses tables reflect the expenses of both the S&P 500 Stock Master Portfolio (the "Master Portfolio") and the Fund.2The Example reflects the expenses of both the Master Portfolio and the Fund.3Institutional Shares commenced operations on May 1, 2007. For the period from September 11, 2000 to April 30, 2007, the performance data includes the performance of the Fund's Class A Shares. Institutional and Class A Shares of the Fund would have substantially similar performance because the Shares are invested in the same portfolio of securities.
