The Fund may also use derivatives to hedge its investment portfolio against interest rate risks or to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;seek to enhance its return. Derivatives are financial instruments whose value is derived from another security, a &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;commodity (such as oil or gold), a currency or an index such as the Russell 1000&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 5pt; position: relative; top: -3.25pt;"&gt;&#xae;&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; Index. The derivatives that the Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;may use include options on portfolio positions or currencies, financial and currency futures, options on such futures, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;forward foreign currency transactions and swaps (including total return swaps, some of which may be referred to as &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;contracts for difference).&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 3pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;In pursuing its investment objective, the Fund may utilize short positions, which arise where the Fund sells a security &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;or basket of securities it does not own by delivery of borrowed securities or where the Fund has entered into a &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;derivative instrument that provides economic exposure similar to a short sale of a security or basket of securities. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Fund expects to implement short positions through short sales of any instrument that the Fund may purchase for &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investment or by using options, futures, forwards, swaps or other derivatives.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 3pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may also invest in indexed and inverse securities.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.0626pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 3pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund is a &#x201c;feeder&#x201d; fund that invests all of its assets in the Master Portfolio, which has the same investment &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;objective and strategies as the Fund.

Institutional Shares commenced operations on September 19, 2023. As a result, for periods prior to September 19, 2023, the chart and table are based on the performance of the Master Portfolio in which the Fund invests all of its assets, adjusted to reflect the estimated annual fund fees and operating expenses of the Institutional Shares of the Fund. The table compares the Fund&#x2019;s performance to that of the Russell 1000&#xae; Index. To the extent that dividends and distributions have been paid by the Master Portfolio, the performance information for the Fund in the chart and table assumes reinvestment of the dividends and distributions. As with all such investments, past performance (before and after taxes) is not an indication of future results. The table includes all applicable fees and sales charges. If BlackRock and its affiliates had not waived or reimbursed certain Master Portfolio and/or Fund expenses during these periods, the Master Portfolio&#x2019;s/Fund&#x2019;s return would have been lower. Updated information on the Fund&#x2019;s performance, including its current net asset value, can be obtained by visiting www.blackrock.com or can be obtained by phone at (800) 882-0052. &lt;/span&gt;&lt;/div&gt;</oef:PerformanceNarrativeTextBlock>
