[1] Fair value disclosure shows financial instruments which are not measured at fair value in the consolidated balance sheets, but for which the fair value is estimated for disclosure purposes.
[2] Investments are measured at fair value using NAV as a practical expedient. These investments have not been classified in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the consolidated balance sheet.
