Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Financial Instruments and Derivative Financial Instruments | Note 9 - Financial Instruments and Derivative Financial Instruments: Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash, cash equivalents, and trade accounts receivable. The Company places its cash, cash equivalents with high credit quality financial institutions, and evaluates the credit worthiness of these financial institutions on a regular basis. Concentrations of credit risk with respect to trade accounts receivable are limited due to the large number of customers comprising the Company's customer base and their geographic dispersion. At March 31, 2023 and 2022, the Company had no significant concentrations of credit risk. Letters of Credit The Company has entered into standby letter of credit agreements with financial institutions relating to the guarantee of future performance on certain contracts. At March 31, 2023 and 2022, the Company was contingently liable on outstanding standby letters of credit aggregating $12,842 and $12,233, respectively. Fair Value of Financial Instruments The estimates of the fair value of financial instruments are summarized as follows: Cash and cash equivalents: The carrying amount of cash and cash equivalents approximates fair value due to the short-term maturity of these instruments and are considered Level 1 assets in the fair value hierarchy. Short-term and long-term debt: The carrying values of credit facilities with variable rates of interest approximates fair values and is considered a Level 2 liability in the fair value hierarchy.
