Share-based Compensation, Allocation and Classification in Financial Statements [Abstract] |
Share-Based Compensation | Share-Based Compensation Share-based compensation expenses for all stock options granted or modified are based on their estimated grant-date fair values. These compensation costs are recognized on a straight-line basis over the requisite service period of the award. The Company estimates forfeitures expected to occur in determining the amount of compensation cost to be recognized in each period. As of June 30, 2018, 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. The fair value of each restricted stock unit ("RSU") grant is determined based on the market price of the Company's common stock on the grant date for awards classified as equity and on each reporting date for awards classified as liability. 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. Compensation cost is recognized based on management’s best estimate of the performance goals that will be achieved at the end of the performance period, taking into account expected forfeitures. If the minimum performance goals are not expected to be met, no compensation cost will be recognized and any recognized compensation cost will be reversed. In February 2015, the Company's Board of Directors adopted the 2015 Incentive Award Plan (the "2015 Plan"), replacing the 2005 Equity Incentive 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 RSU or deferred stock awards. As of June 30, 2018, the Company had 77,250 RSUs and 80,000 stock options granted and outstanding and 4,742,750 shares of common stock available for future grant under the 2015 Plan. In February 2018, the Compensation Committee of the Company's Board of Directors awarded a total of 80,000 stock options to four senior executives under the 2015 Plan which will vest over the four-year requisite service period. The fair values of these stock options were estimated on the date of grant using a closed-form option valuation model (Black-Scholes). The following table provides the assumptions used in the calculation of grant-date fair values of these stock options based on the Black-Scholes option pricing model:
Weighted-average grant-date fair value | $ | 8.09 |
Expected volatility | 33.18 | %
Risk-free interest rate | 2.62 | %
Expected dividend yield | 5.40 | %
Expected term in months | 72 |
Expected volatilities are based on historical volatility of the Company’s stock over the term of the stock options. The Company estimated the expected term of stock options, which represents the period of time that stock options granted are expected to be outstanding, by using historical exercise patterns and post-vesting termination behavior. The risk-free interest rate is determined based on U.S. Treasury yields with equivalent remaining terms in effect at the time of the grant. As of June 30, 2018, the Company had $0.6 million of unrecognized compensation expense related to stock options awarded under the 2015 Plan, which will be recognized ratably over the remaining vesting period of approximately 3.6 years. As of June 30, 2018, the Company had the following RSU awards outstanding. These awards were granted to the Company’s senior management and key employees and will vest based upon the Company's performance during the three-year performance period:
Grant year | 2016 |
Three-year performance period ending December 31, | 2018 |
Vesting shares, target (net of forfeited) | 77,250 |
Vesting shares, maximum (net of forfeited) | 144,844 |
In March 2018, based on certification by the Compensation Committee of the Company's Board of Directors of the results of the three-year performance period ended December 31, 2017, all of the outstanding RSUs granted in 2015 expired unvested because the Company did not meet the minimum three-year performance threshold. In March 2017, a total of approximately $3.6 million was paid upon 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. As of June 30, 2018, 18,500 target RSUs granted in 2016 have been forfeited because the recipients were no longer employed by the Company. No RSUs were awarded during the six months ended June 30, 2018.
