[1] Cash equivalents include funds held in money market instruments and are reported at their current carrying value, which approximates fair value due to the short-term nature of these instruments and are included in cash and cash equivalents in the consolidated balance sheet.
[2] Redeemable noncontrolling interests represents a put option that owners of interests in a certain subsidiary have the right, in certain circumstances, to require the Company to acquire either a portion of, or all of, the remaining ownership interests held by them. The Company determines the fair value of the redeemable noncontrolling interests based on unobservable inputs considering the assumptions that market participants would make in pricing the obligation. Given the significance of the unobservable inputs, the valuations are classified in level 3 of the fair value hierarchy. See Note 15.
