4. Marketable Securities
The following is a summary of our marketable securities (in thousands):
As of April 30, 2021 and January 31, 2021, the contractual maturities of our marketable securities were all less than one year. To determine whether a decline in value is other-than temporary, we evaluate, among other factors: the duration and extent to which the fair value has been less than the carrying value and our intent and ability to retain the marketable securities for a period of time sufficient to allow for any anticipated recovery in fair value. Based on the available evidence, we concluded that the gross unrealized losses on the marketable securities as of April 30, 2021 and January 31, 2021 are temporary in nature.
The entire disclosure for investments in certain debt and equity securities.
