Held-to-maturity

Restricted cash, cash equivalents and investments include collateral that has been provided or pledged to insurance carriers for workers’ compensation and state workers’ compensation programs. Our insurance carriers and certain state workers’ compensation programs require us to collateralize a portion of our workers’ compensation obligation. The collateral typically takes the form of cash and cash equivalents and highly rated investment grade securities, primarily in debt and asset-backed securities. The majority of our collateral obligations are held in a trust at the Bank of New York Mellon (“Trust”).

The amortized cost and estimated fair value of our held-to-maturity investments held in Trust, aggregated by investment category as of March 31, 2024 and December 31, 2023, were as follows:

Total held-to-maturity investments	$	117,109	$	114,899

Actual maturities may differ from contractual maturities because the issuers of certain debt securities have the right to call or prepay their obligations without penalty. We have no significant concentrations of counterparties in our held-to-maturity investment portfolio.

Unrealized gains and losses related to investments still held at March 31, 2024 and March 26, 2023, which are included in selling, general and administrative expense on our Consolidated Statements of Operations and Comprehensive Income (Loss), were as follows:
