STOCK-BASED COMPENSATION

The Company accounts for compensation expense associated with stock options based on the fair value of the options on the date of grant.

The Company's net income for the three months ended March 31, 2013 and 2012 includes approximately $361,000 and $383,000, respectively of noncash compensation expense related to the Company's stock options. The noncash compensation expense related to all of the Company's stock-based compensation arrangements is recorded as a component of selling, general and administrative expenses.

The estimated fair value of each option award granted was determined on the date of grant using the Black-Scholes option valuation model. The following weighted-average assumptions were used for the options granted during the three months ended March 31, 2013 and 2012:
