EXHIBIT 12.1 RATIO OF EARNINGS TO FIXED CHARGES The following table sets forth our ratio of earnings to fixed charges and our ratio of earnings to combined fixed charges and preferred stock dividend requirements for the periods indicated: Year Ended December 31, ----------------------------------------- 2001 2002 2003 2004 2005 ------ ------ ------ ------ ----- Ratio of earnings to fixed charges (1) 28.47x 25.05x 21.20x 16.72x 9.72x Ration of earnings to combined fixed charges and preferred stock dividend requirements (1) 24.07x 24.62x 21.20x 16.72x 9.72x (1) For this purpose, "earnings" means net income before (a) taxes, (b) adjustment for minority interest of $1,077,000 in 2003, $1,875,000 in 2004 and $5,809,480 in 2005, (c) interest expense and amortization of debt issuance costs on all indebtedness, and (d) interest portion of rental expense. For this purpose, "fixed charges" means interest expense and amortization of debt issuance costs on all indebtedness, and interest portion of rental expense. Effective April 1, 2004, we began recognizing expense for stock-based compensation using the fair value based method of accounting described in Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based Compensation," as amended. We have chosen the retroactive restatement method described in SFAS No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure," which amended SFAS No. 123. As a result, financial information for all prior periods presented above have been restated to reflect the salaries and employee benefits expense that would have been recognized had the recognition provisions of SFAS No. 123 been applied from its original effective date.
