Stock Compensation

The Compensation Committee of our Board of Directors approved the grant of RSUs and performance share units (PSUs) shown in the table below during 2019.

* Weighted-average per share

We calculated the fair value of the RSUs at grant date based on the closing market price of our common stock at the date of grant. The number of PSUs that ultimately vest is contingent on achieving specified return on invested capital targets and specified margin targets, with an even distribution between the two targets. We estimated the fair value of the PSUs at grant date based on the closing market price of our common stock at the date of grant adjusted for the value of assumed dividends over the period because the awards are not dividend protected.

We paid $2 of cash to settle RSUs. We issued 0.7 million and 0.2 million shares of common stock based on the vesting of RSUs and PSUs during 2019. We recognized stock compensation expense of $5 and $4 during the first quarters of 2019 and 2018. At March 31, 2019, the total unrecognized compensation cost related to the nonvested awards granted and expected to vest was $37. This cost is expected to be recognized over a weighted-average period of 2.3 years.
