EBP, Fully Benefit-Responsive Investment Contract [Line Items] |
INVESTMENT CONTRACTS | INVESTMENT CONTRACTS The Plan's Managed Income Fund provides a stable value investment option that includes fully benefit-responsive synthetic investment wrap contracts which assure the book value of investments in that fund for Plan participants. The fund’s underlying assets, which are held in a trust, utilize wrap contracts issued by four financial institutions as of December 31, 2024 and 2023. The fund’s underlying investments, usually a portfolio owned by the Plan, consist primarily of high quality, intermediate term fixed income securities and guaranteed investment contracts. The contracts provide that participants execute plan transactions at contract value. Contract value represents contributions made to the fund, plus credited interest, less participant withdrawals, without regard to changes in the fair value of the investments and securities underlying the fund. The rates for crediting interest are reset periodically based on market rates of other similar investments, the current yield of the underlying investments and the spread between the market value and contract value. The interest crediting rate cannot be less than 0%. Certain events initiated by the Plan Sponsor, such as a plan termination or a plan merger, would limit the ability of the Plan to administer participant-level transactions at contract value or may allow for the termination of the wrap contract at market value, rather than contract value. The Plan Sponsor does not believe that any events that may limit the ability of the Plan to transact at contract value are probable as of December 31, 2024 or the date these financial statements are issued.
