Income tax benefit realized on disqualifying dispositions of stock acquired by exercise of incentive stock options	$ 771,000	$ 78,000
Terms of award					The number of RSUs that vest is determined annually, for each year in the five-year period from date of grant, by multiplying the number of RSUs granted by the sum of (a) the average of the percentage change (positive or negative) in operating income and diluted earnings per share in each of the 5 years as compared to operating income and diluted earnings per share reported in the Company's 2011 fiscal year, plus (b) 5%, rounded to the nearest whole number, less (c) the number of RSUs previously vested.					Options granted under the Plans generally become exercisable in either five equal annual installments commencing on the first anniversary of the date of grant or 100% on the fifth anniversary from the date of grant, subject to acceleration in certain circumstances. All options granted under the Plans expire on the tenth anniversary of the date of grant. Under the Plans, the exercise price of each option equals the fair market value of the Company's Common Stock on the date of grant.			Shares of restricted stock generally are granted under the 2011 EIP subject to vesting in three year annual installments or 100% on the fifth anniversary of the date of grant and the shares of restricted stock remain subject to forfeiture unless the grantee remains continuously employed with the Company or a subsidiary thereof through the applicable vesting date.
