[1] Estimated using a blended approach of historical and implied volatility. Historical volatility is based on the historical movement of Hilton's stock price for a period that corresponds to the expected term of the options at the date of grant.
[2] Estimated based on the expected quarterly dividend and the three-month average stock price at the date of grant.
[3] Based on the yield of a U.S. Department of Treasury instrument with a similar expected term of the options at the date of grant.
[4] Estimated using the midpoint of the vesting period and the contractual term of the options as we do not have sufficient historical share option exercise data to estimate the term of the options.
