The Company obtains the fair value from third-party pricing services. The pricing services utilize industry standard valuation models, including both income and market-based approaches and observable market inputs to determine value. These observable market inputs include reportable trades, benchmark yields, credit spreads, broker/dealer quotes, bids, offers and other industry and economic events. The Company assessed each debt security (see Note 1 for information on composition of the portfolio) with gross unrealized losses for credit impairment. As part of that assessment, the Company concluded that it does not intend to sell and it is more-likely-than-not that the Company will not be required to sell, prior to the recovery of the amortized cost basis. The Company did not recognize impairment for the year ended December 30, 2022. The following table shows the fair value of investments AFS by contractual maturity (dollars in thousands):
