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. As of June 30, 2019, we had available up to 1,625,682 shares of common stock to issue under this Plan.

TABLE 11.1

The following table details our issuance of restricted stock units and the aggregate weighted average grant date fair values under these plans for the years indicated.



	Six Months Ended June 30,
(dollars in millions)	2019		2018
Restricted stock units	1,128,701		937,155
Weighted average grant date fair values	$	12	$	12

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.

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