[1] Represents the Company’s conversion option to acquire 73% of the outstanding common stock in the Company’s consolidated VIE, which is located in Other assets on the Company’s Unaudited Condensed Consolidated Balance Sheets. See Footnote 3, Variable Interest Entity, for further information. The conversion option was calculated using an internal model that utilizes as its basis, unobservable inputs, including estimated interest rates based upon the estimated market interest rate which the VIE would have paid on a high-yield note in the open market. The remaining investment in Pathway has been eliminated in consolidation.

[2] Represents the Company's obligation to pay benefits under its non-qualified deferred compensation plans, which is included in Other noncurrent liabilities on the Company's Unaudited Condensed Consolidated Balance Sheets. The obligation to pay benefits is based on participants’ allocation percentages to plan investments. The investments are measured using quoted market prices.

[3] Represents the estimated fair value of the additional cash consideration payable in connection with the Company’s acquisitions that are contingent upon the achievement of certain performance milestones. The Company estimated the fair value using expected future cash flows over the period in which the obligations are expected to be settled, and applied a discount rate that appropriately captures a market participant’s view of the risk associated with the obligation. The liabilities are included in Other current liabilities and Other noncurrent liabilities on the Company’s Unaudited Condensed Consolidated Balance Sheets, depending on the period of expected payout.
