The dividend yield is based on the Company’s historical dividend payments. The Company used the historical average period from the Company’s issuance of an option to its exercise or cancellation and the average remaining years until expiration for the Company’s outstanding options to estimate the expected life of options granted in 2011 and 2010 for which the Company had sufficient historical exercise data. The Company used the “simplified method” to estimate the expected life of certain options granted in 2010 for which sufficient historical data was not available. The risk-free rate is derived from public data sources at the time of each option grant. Compensation cost is recognized over the requisite service period of the option using the straight-line method. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">Option activity with respect to the Company’s plans, excluding the performance-contingent incentive options referenced further below, was as follows: </div> <div align="center"> <table style="font-size: 10pt;
