Fair Value Disclosures [Abstract]

Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following tables summarize our financial assets and financial liabilities measured at fair value on a recurring basis by level within the fair value hierarchy except for certain investments that are measured at fair value using the net asset value per share (or its equivalent) as a practical expedient and are excluded from the leveling information provided in the tables below. Fair value amounts presented below are intended to permit reconciliation of the fair value hierarchy to the amounts presented on our Consolidated Balance Sheets.
