Our officers generally receive annual grants of stock options and restricted stock on or about March 1 of each year. Restricted stock grants are also made annually to directors and certain other employees. Dividends received on restricted stock are non-forfeitable and are paid at the same rate and on the same date as on shares of Common Stock. Dividends paid on subsequently forfeited shares are expensed. Additional total return-based restricted stock may be issued at the end of the three-year periods if actual performance exceeds certain levels of performance. Such additional shares, if any, would be fully vested when issued. No expense is recorded for additional shares of total return-based restricted stock that may be issued at the end of the three-year period since that possibility is already reflected in the grant date fair value. The following table sets forth the number of shares of Common Stock reserved for future issuance:

	December 31,
	2011	2010
Outstanding stock options and warrants	1,224,455	1,495,196

Stock options issued prior to 2005 vest ratably over four years and remain outstanding for 10 years. Stock options issued beginning in 2005 vest ratably over a four-year period and remain outstanding for seven years. The value of all options as of the date of grant is calculated using the Black-Scholes option-pricing model and is amortized over the respective vesting or service period. The fair values of options granted during 2011, 2010 and 2009 were $6.47, $4.96 and $1.82, respectively, per option. The fair values of the options granted were determined at the grant dates using the following assumptions:

Risk free interest rate (1)	2.4	%	2.6	%	2.3	%
Common stock dividend yield (2)	5.0	%	5.9	%	9.0	%

Average expected option life (years) (4)	5.75		5.75		5.75
