Question:
at the average grant date fair value per share what is the value in thousands of the shares outstanding but not yet earned under incentive shares at the end of the year ? \\n


pre_text: the grant date fair value of options is estimated using the black-scholes option-pricing model .
the weighted-average assumptions used in valuations for 2017 , 2016 and 2015 are , respectively : risk-free interest rate , based on u.s .
treasury yields , 1.7 percent , 1.9 percent and 1.9 percent ; dividend yield , 3.6 percent , 3.8 percent and 3.1 percent ; and expected volatility , based on historical volatility , 24 percent , 27 percent and 28 percent .
the expected life of each option awarded is seven years based on historical experience and expected future exercise patterns .
perfo rmance shares , restricted stock and restricted stock units the company 2019s incentive shares plans include performance shares awards which distribute the value of common stock to key management employees subject to certain operating performance conditions and other restrictions .
the form of distribution is primarily shares of common stock , with a portion in cash .

performance shares awards are accounted for as liabilities in accordance with asc 718 , compensation 2013 stock compensation , with compensation expense adjusted at the end of each reporting period to reflect the change in fair value of the awards .
as of september 30 , 2016 , 4944575 performance shares awarded primarily in 2013 were outstanding , contingent on the company achieving its performance objectives through 2016 and the provision of additional service by employees .
the objectives for these shares were met at the 86 percent level at the end of 2016 , or 4252335 shares .
of these , 2549083 shares were distributed in early 2017 as follows : 1393715 issued as shares , 944002 withheld for income taxes , and the value of 211366 paid in cash .

incentive shares plans also include restricted stock awards which involve distribution of common stock to key management employees subject to cliff vesting at the end of service periods ranging from three to ten years .
the fair value of restricted stock awards is determined based on the average of the high and low market prices of the company 2019s common stock on the date of grant , with compensation expense recognized ratably over the applicable service period .
in 2017 , 130641 shares of restricted stock vested as a result of participants fulfilling the applicable service requirements .

as of september 30 , 2017 , 12.9 million shares remained available for award under incentive shares plans .
changes in shares outstanding but not yet earned under incentive shares plans during the year ended september 30 , 2017 follow ( shares in thousands ) : average grant date shares fair value per share .
