The performance-based share awards are subject to either a market condition or a performance condition. For awards subject to a market condition, the performance metric is the Company's total shareholder return, which includes share price appreciation and dividends paid during the three-year term of the award, measured against a peer group of companies. These awards cliff vest at the end of three years. The number of performance-based shares that will ultimately vest is based on the level of market performance achieved, ranging between 0% and 200% of the shares originally awarded, and will be settled in stock. For awards subject to a performance condition, the performance metric is the Company's average return on invested capital, over the three-year term. These awards cliff vest at the end of three years. The number of performance-based shares that will ultimately vest is based on the level of performance achieved ranging between 0% and 200% of the shares originally awarded, and will be settled in stock. The time-vesting restricted and deferred stock awards vest ratably over three to five years. The weighted average grant-date fair value of the 2017 time-vesting stock awards was $53.35 and the performance-based stock awards was $51.91. The fair value of the performance-based shares subject to a market condition awarded in 2017 was calculated using a Monte Carlo valuation model, including a weighted average stock price volatility of 21.1%, an expected term of three years, and a weighted average risk-free interest rate of 1.43%.

The aggregate market value of the shares released on the vesting dates was $9 for the three months ended March 31, 2017.
