(a)Collective trust funds consist of bond funds with corporate and U.S. treasury debt securities, equity funds with global equity index, infrastructure and real estate securities and short-term investment strategies comprised of instruments issued or fully guaranteed by the U.S. government and/or its agencies and multi-strategy funds, which are valued using the net assets provided by the administrator of the fund. The value of each fund is based on the readily determinable fair value of the underlying assets owned by the fund, less liabilities, and then divided by the number of units outstanding.
(b)In June 2023, the Company purchased a buy-in GAC which was initially recorded at the $1.4 billion purchase price and subsequently adjusted to fair value using changes to market conditions impacting the cash flow assumptions that were priced into the original contract.
(c)As a practical expedient, certain investment classes which hold securities that are not readily available for redemption and are measured at fair value using the net asset value ("NAV") per share (or its equivalent) have not been classified in the fair value hierarchy. The primary investment classes include alternative, fixed income and real estate funds. Certain investments report NAV per share on a month or quarter lag. There are no material unfunded commitments with respect to these investment classes.
