20 Example: This Example is intended to help you compare the cost of investing in 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 of 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 remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 1 Year 3 Years 5 Years 10 Years Investor A Shares $817 $1,492 $2,188 $4,026 Investor C Shares $482 $1,237 $2,106 $4,341 Institutional Shares $278 $ 932 $1,611 $3,421 You would pay the following expenses if you did not redeem your shares: 1 Year 3 Years 5 Years 10 Years Investor C Shares $382 $1,237 $2,106 $4,341 Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or turns over its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund s performance. For the period August 7, 2014 (commencement of operations) through August 31, 2014, the Fund s portfolio turnover rate was 5% of the average value of its portfolio. Principal Investment Strategies of the Fund The Fund seeks to achieve its investment objective by allocating to multiple affiliated and unaffiliated investment managers ( Sub-Advisers ) that employ a variety of alternative investment strategies. Each of the Sub-Advisers generally provides day-to-day management for a portion of the Fund s assets. Each Sub-Adviser may use different investment strategies in managing Fund assets, acts independently from the others, and uses its own methodology for selecting investments. BlackRock is responsible for identifying and retaining (subject to approval of the Trust s Board of Trustees (the Board )) the Sub-Advisers for the selected strategies and for monitoring the services provided by the Sub-Advisers. BlackRock reviews a number of qualitative and quantitative factors as part of its process for selecting and monitoring the Sub-Advisers, as described in the Details About the Fund section of this prospectus. BlackRock is also responsible for selecting the Fund s alternative investment strategies and for determining the amount of Fund assets to allocate to each Sub-Adviser. Based on BlackRock s ongoing evaluation of the Sub-Advisers, BlackRock may adjust allocations among Sub-Advisers, or make recommendations to the Board with respect to the hiring, termination or replacement of Sub-Advisers. The primary strategies that will initially be employed by the Fund and its Sub-Advisers include: Relative Value, Event Driven, Fundamental Long/Short and Directional Trading. Relative Value Strategies seek to profit from mispricing of financial instruments relative to each other or historical norms. These strategies utilize quantitative and qualitative analysis to identify securities or spreads between securities that deviate from their theoretical fair value and/or historical norms. Event Driven Strategies concentrate on companies that are subject to corporate events such as mergers, acquisitions, restructurings, spin-offs, shareholder activism, or other special situations that alter a company s financial structure or operating strategy. The intended goal of event driven strategies is to profit when the price of a security changes to reflect more accurately the likelihood and potential impact of the occurrence, or non-occurrence, of the extraordinary event. This can be done by taking a long position in a security or other financial instrument that is believed to be underpriced or a short position in a security or other financial instrument that is believed to be overpriced. Fundamental Long/Short Strategies involve buying or selling securities believed to be overpriced or underpriced relative to their potential value. Investment strategies within the fundamental long/short discipline include long and short equity- or credit-based strategies that emphasize a fundamental valuation framework and equity active value strategies where an active role is taken to enhance corporate value. 4
