The following table presents certain quantitative information about the significant unobservable inputs used in valuing the Company’s level 3 fair value measurements:



	Quantitative Information About Level 3 Fair Value Measurements
	Valuation Techniques	Unobservable Input	Fair Value at December 31, 2017		Range at December 31, 2017	Fair Value at September 30, 2018		Range at September 30, 2018

Contingent payment arrangements represent the present value of the expected future settlement of contingent payment arrangements related to the Company’s investments in consolidated Affiliates. As of September 30, 2018, there were no changes to growth rates or discount rates that had a significant impact to contingent payment arrangements.

Affiliate equity repurchase obligations include agreements to repurchase Affiliate equity. As of September 30, 2018, there were no changes to growth or discount rates that had a significant impact to Affiliate equity repurchase obligations recorded in prior periods.

Investments Measured at NAV as a Practical Expedient

The Company’s Affiliates sponsor investment products in which the Company and its Affiliates may make general partner and seed capital investments. The Company uses the net asset value (“NAV”) of these investments as a practical expedient for their fair value and reports these products within Other investments and assets. The following table summarizes the nature of the Company’s investments, unfunded commitments and any related liquidity restrictions or other factors that may impact the ultimate value realized:



	December 31, 2017				September 30, 2018
Category of Investment	Fair Value		Unfunded Commitments		Fair Value		Unfunded Commitments
Private equity funds⁽¹⁾	$	156.1	$	98.8	$	185.4	$	130.4
Other funds⁽²⁾	8.9		—		7.4		—
Other investments⁽³⁾	$	165.0	$	98.8	$	192.8	$	130.4

___________________________


⁽¹⁾	The Company uses NAV as a practical expedient one quarter in arrears (adjusted for current period calls and distributions) to determine the fair value. These funds primarily invest in a broad range of private equity funds, as well as making direct investments. Distributions will be received as the underlying assets are liquidated over the life of the funds, which is generally up to 15 years.


⁽²⁾	These are multi-disciplinary funds that invest across various asset classes and strategies, including long/short equity, credit and real estate. Investments are generally redeemable on a daily, monthly or quarterly basis.


⁽³⁾	Fair value attributable to the controlling interest was $80.1 million and $115.0 million as of December 31, 2017 and September 30, 2018, respectively.

Other Financial Assets and Liabilities Not Carried at Fair Value

The carrying amount of Receivables and Payables and accrued liabilities, which is reported in the Consolidated Condensed Balance Sheets, approximates fair value because of the short-term nature of these instruments. The carrying value of notes receivable, which is reported in Other investments and assets, approximates fair value because interest rates and other terms are at market rates. The carrying value of the credit facilities, which is reported in Senior debt in the Consolidated Condensed Balance Sheets, approximates fair value because the credit facilities have variable interest based on selected short-term rates. The following table summarizes the Company’s other financial liabilities not carried at fair value:



	December 31, 2017				September 30, 2018
	Carrying Value		Fair Value		Carrying Value		Fair Value		Fair Value Hierarchy
Senior notes⁽¹⁾	$	745.7	$	765.2	$	746.1	$	743.8	Level 2
Convertible securities	309.9		549.8		311.8		498.7		Level 2
