Fair Value Disclosures [Abstract]

Financial Instruments

Note 5 – Financial Instruments

The Company classifies its financial instruments within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. Three levels of input may be used to measure fair value:

•Level 1 – Observable inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

•Level 2 – Observable inputs are quoted for similar assets and liabilities in active markets or inputs other than quoted prices which are observable for the assets or liabilities, either directly or indirectly through market corroboration, for substantially the full term of the financial instruments.

•Level 3 – Unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. These inputs will be based on the Company’s own assumptions and will require significant management judgement or estimation.

The Company did not have any level 3 investments as of January 31, 2025 and 2024. The following table summarizes the Company’s cash and available-for-sale marketable securities’ amortized cost, gross unrealized gains, gross unrealized losses, and estimated fair value by significant investment category reported as cash and cash equivalents or short-term investments (in thousands):

For available-for-sale debt securities that have unrealized losses, the Company evaluates whether (i) the Company has the intention to sell any of these investments, (ii) it is not more likely than not that the Company will be required to sell any of these available-for-sale debt securities before recovery of the entire amortized cost basis, and (iii) the decline in the fair value of the investment is due to credit or non-credit related factors. Based on this evaluation, the Company determined that for its short-term investments there were no material credit or non-credit related impairments as of January 31, 2025 and 2024.
