As of March 31, 2024 and 2023, the Company evaluated the realizability of the aged accounts receivable, giving consideration to each customer’s financial history and liquidity position, credit rating and the facts and circumstances of collectability on each outstanding account, and did not have a significant reserve for uncollectible accounts.
