14. ACCUMULATED OTHER COMPREHENSIVE INCOME

Accumulated other comprehensive income includes cumulative foreign currency translation adjustments and net of tax, gains and losses on investment securities. The change in the accumulated translation adjustments for fiscal 2012 and 2011, primarily resulted from the impact of changes in the Brazilian real, the Polish zloty, the Australian dollar, the Japanese yen, the British pound, and the Singapore dollar in relation to the U.S. dollar on the net assets of Legg Mason's subsidiaries in Brazil, Poland, Australia, Japan, the United Kingdom, and Singapore, for which the real, the zloty, the Australian dollar, the yen, the pound, and the Singapore dollar are the functional currencies, respectively.

A summary of Legg Mason's accumulated other comprehensive income as of March 31, 2012 and 2011, is as follows:

	2012		2011
