Investments in marketable equity securities consist of investments in the common stock of industrial and other companies. As of April 3, 2021 and March 28, 2020, non-marketable equity investments included contributions of $15.0 million to equity-method investments in community-based initiatives that buy and sell our homes and provide home-only financing to residents of certain manufactured home communities. Other non-marketable equity investments included investments in other distribution operations. We record investments in fixed maturity securities classified as available-for-sale at fair value and record the difference between fair value and cost in AOCI. The following tables summarize our available-for-sale debt securities, gross unrealized gains and losses and fair value, aggregated by investment category (in thousands):

We are not aware of any changes to the securities or issuers that would indicate the losses above are indicative of credit impairment as of April 3, 2021. Further, we do not intend to sell the investments, and it is more likely than not that we will not be required to sell the investments, before recovery of their amortized cost. The amortized cost and fair value of our investments in available-for-sale debt securities, by contractual maturity, are shown in the table below (in thousands). Expected maturities differ from contractual maturities as borrowers may have the right to call or prepay obligations, with or without penalties.
