Losses are not allocated to participating securities.

Dividends declared on participating securities during the three and nine months ended August 31, 2011 amounted to approximately $934,000 and $2,414,000, respectively, and $559,000 and $1,621,000 for the three and eight months ended August 31, 2010, respectively. Undistributed earnings are allocated to participating securities based upon their right to share in earnings if all earnings for the period had been distributed.
