The Company’s estimated taxes payable as of March 31, 2016 were sufficient to fully recognize $0.1 million of excess tax benefits related to stock option exercises as a cash inflow from financing activities in its Condensed Consolidated Statement of Cash Flows for the three months ended March 31, 2016.

During the first quarter of 2017, the Company granted stock options under its long-term incentive plan (“LTIP”) that are subject only to time vesting over a three-year period. For the purposes of determining the fair value of stock option awards, the Company used the Black-Scholes option pricing model and the assumptions set forth in the table below:

Number of options granted42,477
Dividend yield1.49%
Expected volatility25.52%
Risk-free interest rate1.67%
Expected term (years)4.0

The fair value of these stocks options is amortized on a straight-line basis over the vesting period. As of March 31, 2017, unrecognized compensation expense related to stock options granted was $1.9 million, to be recognized over a weighted average remaining period of 2.3 years.

During the first quarter of 2017, the Company granted 13,697 nonvested restricted shares and 1,332 nonvested restricted stock units under its LTIP that are subject only to time vesting, generally over a three-year period. The fair value of these awards is based on the trading price of the Company’s common stock on the date of grant. The Company adjusts the grant date fair value of these awards for expected forfeitures based on historical experience. As of March 31, 2017, unrecognized compensation expense related to the nonvested shares was $3.6 million, to be recognized over a weighted average remaining period of 2.0 years, and unrecognized compensation expense related to nonvested restricted stock units was $0.3 million, to be recognized over a weighted average remaining period of 2.3 years.
