IHC and AMIC each have share-based compensation plans. The following is a summary of the activity pertaining to each of these plans.

Under the terms of IHC’s stock-based compensation plan, option exercise prices are more than or equal to the quoted market price of the shares at the date of grant; option terms are generally five years; and vesting periods are generally three years. The fair value of an option award is estimated on the date of grant using the Black-Scholes option valuation model. In addition to stock options, the Company has also granted restricted stock units and share appreciation rights (“SARs”) under the plan. Restricted share units are valued at the quoted market price of the shares at the date of grant and have a three year vesting period. Compensation costs for options and restricted share units are recognized over the stated vesting periods on a straight-line basis. Exercise prices of SARs are more than or equal to the quoted market price of IHC shares at the date of the grant and have three year vesting periods. The fair value of SARs is calculated using the Black-Scholes valuation model at the grant date and each subsequent reporting period until settlement. Compensation cost is based on the proportionate amount of the requisite service that has been rendered to date. Once fully vested, changes in fair value of the SARs continue to be recognized as compensation expense in the period of the change until settlement.

At June 30, 2016, there were no shares available for future stock-based compensation grants under IHC’s stock incentive plans.
