[3] Amounts for 2010 included a loss of $1.2 billion related to the disposition of Revel included within the Institutional Securities business segment, a gain of approximately $570 million related to the Company’s sale of Retail Asset Management within the Asset Management business segment and a gain of $775 million related to the legal settlement with DFS.
[4] RSUs that are considered participating securities participate in all of the earnings of the Company in the computation of basic EPS, and, therefore, such RSUs are not included as incremental shares in the diluted calculation.
[5] Summation of the quarters’ earnings per common share may not equal the annual amounts due to the averaging effect of the number of shares and share equivalents throughout the year.
