1. | The plan assets are invested in investment funds that hold a diversified portfolio of: (i) U.S. and international debt and equity securities; (ii) fixed income securities such as corporate bonds and government bonds; (iii) mortgage-related securities; and (iv) cash and cash equivalents.
2. | The market value of these funds has not been categorized in the fair value hierarchy and is being presented in the table above to permit a reconciliation of the fair value hierarchy to the Consolidated Balance Sheets. Equity investment funds measured at fair value using the NAV practical expedient are managed by an investment adviser registered with the SEC
under the Investment Advisers Act of 1940 and can be redeemed with five business days' notice on the 15th (or last business day prior to the 15th) and on the last business day of each month. A business day is every day that the New York Stock Exchange is open. Diversified investment funds measured at fair value using the NAV practical expedient are unitized mutual funds without externally published net asset values, which can be redeemed daily without restriction.
3. | This category represents investments in various fixed income funds with multiple registered investment companies. Such funds invest primarily in bonds (including Eurodollar and Yankee bonds), debentures, notes, securities with equity and fixed-income characteristics (such as bonds with warrants attached, convertible bonds, hybrids and certain preferred securities), cash equivalents, securities backed by mortgages and other assets, loans, pooled or collective investment vehicles made up of fixed-income securities, and other fixed-income obligations of banks, corporations and governmental authorities.
4. This category represents investments in equity funds that invest in portfolios comprised primarily of equity and equity-related securities of U.S. and non-U.S. issuers across all market capitalizations.
