Fair Value Of Financial Assets And Financial Liabilities

Long-term borrowings		6,186		6,767		4,690		5,057		Level 2	(3	)

(1) Cash and cash equivalents are carried at either cost or amortized cost that approximates fair value due to their short-term maturities. At September 30, 2012 and December 31, 2011, approximately $46 million and $196 million, respectively, related to cash and cash equivalents held by consolidated sponsored investment funds. Money market funds are valued through the use of quoted market prices, or $1.00, which generally is the NAV of the fund. At September 30, 2012 and December 31, 2011, approximately $17 million and $123 million, respectively, of money market funds were recorded within cash and cash equivalents on the Company’s condensed consolidated statements of financial condition.

(2) The carrying amounts of accounts receivable, due from related parties, accounts payable and accrued liabilities, due to related parties and short-term borrowings approximate fair value due to their short-term nature.

(3) Long-term borrowings are recorded at amortized cost. The fair value of the Company’s long-term borrowings, including the current portion of long-term borrowings, is estimated using market prices at the end of September 2012 and December 2011, respectively. See Note 10, Borrowings, for the fair value of each of the Company’s long-term borrowings.
