Fair Value, Assets Measured on Recurring Basis, Unobservable Input Reconciliation

The following table includes a rollforward of the amounts for the years endedDecember 31, 2013, 2012, and 2011, for financial instruments classified within level 3. The classification of a financial instrument within level 3 is based upon the significance of the unobservable inputs to the overall fair value measurement.

Fair Value Inputs, Assets, Quantitative Information

The following table includes quantitative information as of December 31, 2013 for financial instruments classified within level 3. The table below quantifies information about the significant unobservable inputs used in the fair value measurement of the Company's level 3 financial instruments.

	Quantitative Information about Level 3 Fair Value Measurements
	Fair Value at December 31, 2013		Valuation techniques	Unobservable Inputs	Range
Common and preferred stocks	$	3,474	Discounted cash flows, market multiples, recent transactions, bid levels, and comparable transactions	Market multiples	2x to 3x
Warrants and rights, net	5,805		Model based	Volatility	20% to 100% (weighted average 37%)
Contingent consideration	6,937		Discounted cash flows	Projected Cash Flow and DCF rate	0% to 15%
	$	16,216
Other level 3 assets and liabilities (a)	216,990
Total level 3 assets and liabilities	$	233,206

(a) Quantitative disclosures of unobservable inputs and assumptions are not required for investments for which NAV per share is used as a practical expedient to determine fair value, as their redemption features rather than observability of inputs cause them to be classified as a level 3 type asset within the fair value hierarchy. In addition, the fair value of the Consolidated Funds' investments are determined based on net asset value and therefore quantitative disclosures are not included in the table above. The quantitative disclosures also exclude financial instruments for which the determination of fair value is based on prices from prior transactions.
