Share-based Payment Arrangement [Abstract]

Restricted Stock

We issue restricted stock awards to key employees under our Incentive Compensation Plan (Plan). We issue time-based awards and performance-based awards under this Plan, both of which are based on a three-year vesting period. The grant date fair value of the time-based awards is equal to the price of our common stock on the grant date. The fair value of the performance-based awards is based on a Monte-Carlo simulation valuation of our common stock as of the grant date. The assumptions used for this valuation include stock price volatility, risk-free interest rate and dividend yield. We issued 1,102,607 and 1,988,225 restricted stock units during the six months ended June 30, 2021 and 2020, respectively, including 325,284 and 571,932 performance-based restricted stock units during those same periods, respectively. As of June 30, 2021, we had available up to 4,217,702 shares of common stock to issue under this Plan.

The unvested restricted stock unit awards are eligible to receive cash dividends or dividend equivalents which are ultimately used to purchase additional shares of stock and are subject to forfeiture if the requisite service period is not completed or the specified performance criteria are not met. These awards are subject to certain accelerated vesting provisions upon retirement, death, disability or in the event of a change of control as defined in the award agreements.

The following table summarizes the activity relating to restricted stock units during the periods indicated:

Stock Options

All outstanding stock options were assumed from acquisitions and are fully vested. Upon consummation of our acquisitions, all outstanding stock options issued by the acquired companies were converted into equivalent FNB stock options. We issue shares of treasury stock or authorized but unissued shares to satisfy stock options exercised.

As of June 30, 2021, we had 170,647 stock options outstanding and exercisable at a weighted average exercise price per share of $8.75, compared to 212,982 stock options outstanding and exercisable at a weighted average exercise price per share of $8.32 as of June 30, 2020.

The intrinsic value of outstanding and exercisable stock options at June 30, 2021 was $0.6 million. The aggregate intrinsic value represents the amount by which the fair value of underlying stock exceeds the option exercise price.
