During the six months ended June 30, 2019, the Company granted 3 million RSUs for CBS Corp. Class B Common Stock with a weighted average per unit grant-date fair value of $50.45. RSUs granted during the first six months of 2019 generally vest over a one- to four-year service period. Compensation expense for RSUs is determined based upon the market price of the shares underlying the awards on the date of grant. For certain RSU awards the number of shares an employee earns ranges from 0% to 120% of the target award, based on the outcome of established performance conditions. Compensation expense is recorded based on the probable outcome of the performance conditions.

Total unrecognized compensation cost related to unvested stock option awards at June 30, 2019 was $21 million, which is expected to be recognized over a weighted average period of 2.1 years.
