Held-to-maturity

Restricted cash 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 June 25, 2023 and December 25, 2022, were as follows:

The amortized cost and fair value by contractual maturity of our held-to-maturity investments are as follows:


	June 25, 2023
(in thousands)	Amortized cost		Fair value
Due in one year or less	$	31,087	$	30,716
Due after one year through five years	86,119		82,683

Total held-to-maturity investments	$	117,206	$	113,399

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 June 25, 2023 and June 26, 2022, which are included in selling, general and administrative expense on our Consolidated Statements of Operations and Comprehensive Income (Loss), were as follows:
