This table is the responsibility of the Company’s management. Our responsibility is to express an opinion based on our audits of the consolidated financial statements.

In our opinion, the senior securities table, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly in all material respects the information set forth therein.
