Stock Plans [Abstract]

Stock Plans

(14)    Stock Plans:

At March 31, 2019, we haveseven stock-based compensation plans under which grants were made and awards remained outstanding. No further awards may be granted under six of the plans: the 1996 Equity Incentive Plan (the 1996 EIP), the Amended and Restated 2000 Equity Incentive Plan (the 2000 EIP), the 2009 Equity Incentive Plan (the 2009 EIP), the 2013 Equity Incentive Plan (the 2013 EIP), the Deferred Fee Plan and the Directors’ Equity Plan. At March 31, 2019, there were approximately 5,667,000shares authorized for grant and approximately 2,759,000 shares available for grant under the 2017 Equity Incentive Plan (the 2017 EIP and together with the 1996 EIP, the 2000 EIP,  the 2009 EIP and the 2013 EIPS, the EIPs).

Performance Shares

As of January 1, 2019,  we had 497,000 outstanding performance shares under the Frontier Long Term Incentive Plan (the LTIP).  The following summary presents information regarding LTIP target performance shares as of March 31, 2019 and changes during the three months then ended with regard to LTIP shares awarded under the 2013 EIP and the 2017 EIP:

	Number of
	Shares
	(in thousands)
Balance at January 1, 2019	497
LTIP target performance shares granted, net	-
LTIP target performance shares earned	(41)
LTIP target performance shares forfeited	(20)
Balance at March 31, 2019	436

For purposes of determining compensation expense, the fair value of each performance share is measured at the end of each reporting period and, therefore, will fluctuate based on the price of Frontier common stock as well as performance relative to the targets. For the three months ended March 31, 2019 and 2018, we recognized net compensation expense, reflected in “Selling, general and administrative expenses,” of$0million and $1, respectively, for the LTIP.

Restricted Stock

The following summary presents information regarding unvested restricted stock as of March 31, 2019 and changes during the three months then ended with regard to restricted stock granted under the 2013 EIP and the 2017 EIP:

		Weighted
		Average
	Number of	Grant Date		Aggregate
	Shares	Fair Value		Fair Value
	(in thousands)	(per share)		(in millions)
Balance at January 1, 2019	1,858	$	16.02	$	4
Restricted stock granted	5	$	2.33	$	-
Restricted stock vested	(631)	$	19.03	$	(1)
Restricted stock forfeited	(13)	$	16.00
Balance at March 31, 2019	1,219	$	14.41	$	2

For purposes of determining compensation expense, the fair value of each restricted stock grant is estimated based on the closing price of a share of our common stock on the date of the grant. Total remaining unrecognizedcompensation cost associated with unvested restricted stock awards that is deferred at March 31, 2019was $12million, and the weighted average vesting period over which this cost is expected to be recognized is approximately 1 year.

Shares of restricted stock granted during the first three months of 2018totaled 1,897,000 shares. The total fair value of shares of restricted stock granted at March 31, 2018 was approximately $14 million. The total fair value of unvested restricted stock at March 31, 2018was $17 million. The weighted average grant date fair value of restricted shares granted during the three months ended March 31, 2018 was $8.23per share.

We have granted restricted stock awards to employees in the form of our common stock. None of the restricted stock awards may be sold, assigned, pledged or otherwise transferred, voluntarily or involuntarily, by the employees until the restrictions lapse, subject to limited exceptions. The restrictions are time-based. Compensation expense, recognized in “Selling, general and administrative expenses,” of $3 millionfor each of the three month periods ended March 31, 2019 and 2018, respectively, has been recorded in connection with these grants.
