(1) Cash equivalents include highly liquid investments with original maturities of 90 days or less. Cash investments in actively traded money market funds are measured at net asset value and are classified as Level 1. Cash investments in commercial paper are measured at cost, which approximates fair value because of the short time between purchase of the instrument and its expected realization, and are classified as Level 2.

(2) Certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been categorized 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 sheets.
