Hedge funds often impose lockups and notice periods to limit the ability of investors to withdraw capital. We model the investor's decision to withdraw capital as a real option and treat lockups and notice periods as exercise restrictions. Our methodology incorporates time-varying probabilities of hedge fund failure and optimal early exercise. We estimate a two-year lockup with a three-month notice period costs investors 1.5% of their initial investment. The magnitude is sensitive to a fund's age, expected return, and the liquidation cost upon failure. The cost of illiquidity can exceed 10% if the hedge fund manager suspends withdrawals.
