AltShares Merger Arbitrage ETF seeks to provide investment results that closely correspond, before fees and expenses, to the performance of its underlying index, the Water Island Merger Arbitrage USD Hedged Index. The Fund seeks to track the performance of the Underlying Index, which is designed to reflect a global merger arbitrage strategy. The most common approach to merger arbitrage, and the approach the Underlying Index reflects, is to seek to capture the difference between the price at which the stock of a target company in a publicly announced merger, takeover, tender offer, or leveraged buy-out (the "Target") trades after the announcement of the acquisition and the price the acquiring company (the "Acquirer") has agreed to pay for the stock of the Target. The Underlying Index is rebalanced and reconstituted twice per month. The Fund reconstitutes and rebalances on the same schedule as the Underlying Index.
