Share-Based Compensation

Share-Based Compensation

Share-based compensation expense for all share-based payment awards granted or modified is based on the estimated grant-date fair value. The Company recognizes these compensation costs on a straight-line basis over the requisite service period of the award. As of June 30, 2017, all outstanding stock options have a term of ten years from the date of grant and become exercisable in four equal installments on the first through fourth anniversaries of the grant date. The fair value of stock option awards is estimated using the Black-Scholes option pricing model with the grant-date assumptions and weighted-average fair values.

In February 2015, the Company's Board of Directors adopted the 2015 Incentive Award Plan (the "2015 Plan"), replacing the 2005 Equity Incentive Plan (the "2005 Plan") which expired in January 2015. The 2015 Plan was approved at the Company's Annual Meeting of Shareholders in May 2015. A maximum of 4,900,000 shares of common stock are authorized for issuance under the 2015 Plan upon exercise of stock options, stock appreciation rights and other awards, or upon vesting of restricted stock unit ("RSU") or deferred stock awards. As of June 30, 2017, 184,500 RSUs were outstanding and 4,715,500 shares of common stock were available for future issuances under the 2015 Plan.

The Compensation Committee of the Company’s Board of Directors granted RSU awards to the Company’s senior management and key employees which will vest based upon the Company's performance during three-year performance periods ending on December 31, 2017 and 2018:

	Grant Year
	2016	2015
Three-year performance period ending December 31,	2018	2017
Vesting shares, target (net of forfeited)	90,750	93,750
Vesting shares, maximum (net of forfeited)	170,156	175,781

The RSUs vest at the end of a three-year performance period beginning with the year of the grant, and then only if, and to the extent that, the Company’s performance during the performance period achieves the threshold established by the Compensation Committee of the Company’s Board of Directors. Performance thresholds are based on the Company’s cumulative underwriting income, annual underwriting income, and net earned premium growth.

In March 2017, a total of approximately $3.6 million was paid upon the vesting of 61,445 RSUs awarded in 2014 resulting from the attainment of performance goals above the target threshold during the three-year performance period ended December 31, 2016.

In February 2016, 88,074 shares of common stock, net of 58,822 shares withheld for payroll taxes, were issued upon the vesting of 146,896 RSUs awarded in 2013 resulting from the attainment of performance goals above the target threshold during the three-year performance period ended December 31, 2015.

As of June 30, 2017, 5,000 and 5,500 target RSUs granted in 2016 and 2015, respectively, were forfeited because the recipients were no longer employed by the Company.

The fair value of each RSU grant was determined based on the market price of the Company's common stock on the grant date. Compensation cost is recognized based on management’s best estimate that performance goals will be achieved. If such goals are not met, no compensation cost will be recognized and any recognized compensation cost will be reversed.

No stock options or RSUs were awarded during the six months ended June 30, 2017.
