Share-Based Payment Arrangement [Abstract]

Stock-based compensation costs are based on the fair values on the date of grant for stock awards and stock options and on the date of enrollment for the employee stock purchase plans. The fair values of stock awards (such as restricted stock units (“RSUs”) and performance stock units (“PSUs”)) are estimated based on their intrinsic values. The fair values of market stock awards (“MSUs”) are estimated using a Monte Carlo simulation. The fair values of stock options and rights under the Company’s Employee Stock Purchase Plan are estimated using the Black-Scholes option-pricing model.

The following table presents details of stock-based compensation costs recognized in the Condensed Consolidated Statements of Operations (in thousands):
