(3)Certain investments that are measured at fair value using the net asset value (“NAV”) per share (or its equivalent) practical expedient are not 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 statement of financial position. (4)Liability-hedging assets are comprised of investments in fixed income securities or derivatives thereof that are intended to mitigate interest rate risk or reduce the interest rate duration mismatch between the assets and liabilities of the Plan.
