We typically invest in highly-rated securities with low probabilities of default. Our investment policy requires investments to be rated single A or better, limits the types of acceptable investments, concentration as to security holder and duration of the investment. The gross unrealized gains and losses in fiscal 2021 and 2020 were caused primarily by changes in interest rates. The longer the duration of marketable securities, the more susceptible they are to changes in market interest rates and bond yields. As yields increase, those securities with a lower yield-at-cost show a mark-to-market unrealized loss. We anticipate recovering the full cost of the securities either as market conditions improve, or as the securities mature. Accordingly, we believe that the unrealized losses are not as a result of a credit loss. As of December 25, 2021 and December 26, 2020, gross unrealized losses related to our marketable securities portfolio were not material. The contractual maturities of marketable securities were as follows (in thousands):
