Stock-Based Compensation | STOCK-BASED COMPENSATION A summary of stock-based compensation costs follows (in millions):
| Three Months Ended March 31,

Expense included primarily in selling, general and administrative expense | $ | 0.2 |  |  | $ | 0.1 |

As of March 31, 2016, there was $0.9 million of unrecognized compensation cost, adjusted for estimated forfeitures, of which $0.9 million relates to stock options and less than $0.1 million relates to unvested restricted stock units. Unrecognized compensation cost is expected to be recognized over a weighted-average period of 2.6 years. Stock-based compensation cost is measured at the grant date, based on the fair value of the award using the Black-Scholes option pricing model, and is recognized over the vesting period. Stock options vest and become exercisable in equal annual installments over a three or four year period and expire 10 years from the date of grant. Assumptions used in the Black-Scholes option pricing model to value option grants follow. There were no options granted in the three months ended March 31, 2016.
