At December 31, 2016, total compensation cost related to nonvested awards not yet recognized was approximately $34,600,000. The weighted-average period over which this compensation cost is expected to be recognized is approximately three years. The aggregate intrinsic value for SARs and RSUs outstanding at December 31, 2016 and 2015 was approximately $104,200,000 and $104,000,000, respectively. The aggregate intrinsic value for SARs and RSUs vested totaled approximately $62,000,000 and $65,000,000 at December 31, 2016 and 2015, respectively. At December 31, 2016, the weighted-average contractual life for outstanding and exercisable SARs and RSUs was six and five years, respectively. Share-based compensation costs of $19,719,000, $17,717,000, and $16,239,000, were recorded for the years ended December 31, 2016, 2015, and 2014, respectively. The total income tax benefits recognized in the consolidated statements of income and comprehensive income for share-based compensation arrangements were approximately $7,900,000, $7,100,000, and $6,500,000 for 2016, 2015, and 2014, respectively. There have been no modifications to valuation methodologies or methods during the years ended December 31, 2016, 2015, or 2014.

For the years ended December 31, 2016, 2015, and 2014, the fair values for SARs granted were estimated using a Black-Scholes option pricing model with the following weighted-average assumptions, respectively: risk-free interest rate of 1.6%, 2.0%, and 2.8%; dividend yield of 2.7%, 2.6%, and 2.8%; annual historical volatility factor of the expected market price of the Company’s common stock of 19% for each of the three years; an average expected life and estimated turnover based on the historical pattern of existing grants of approximately seven years and 6.2%, respectively. The fair value of RSUs is based on the price of the Company’s stock on the date of grant. The total fair value of shares vested during the years ended December 31, 2016, 2015, and 2014 were $18,200,000, $15,200,000, and $13,800,000, respectively.
