FAIR VALUE MEASUREMENTS FAIR VALUE MEASUREMENTS
Certain investments that are measured at fair value using NAV per share (or its equivalent) as a practical expedient are not required to be categorized in the fair value hierarchy tables. The total fair value of these investments is included in the tables below to permit reconciliation of the fair value hierarchy to amounts presented in the investments footnote (Note 3). These investments have no unfunded commitments, redemption notice periods greater than seven days or other redemption restrictions. As of December 31, 2025 and 2024, there were no investments expected to be sold at a value materially different than NAV.
The table below sets forth the fair value of the investments by level, measured on a recurring basis and held by the DC Master Trust as of December 31, 2025:
