Risks and Uncertainties [Abstract] |
Concentration of Risk | Note 19—Concentration of Risk Credit is generally extended on an uncollateralized basis to almost all customers after review of credit worthiness. Concentration of credit and geographic risk with respect to accounts receivable is limited due to the large number and general dispersion of accounts which constitute the Company’s customer base. The Company periodically performs on-going credit evaluations of its customers. The Company has not historically experienced significant credit losses on collection of its accounts receivable. Excess cash is invested principally in investment grade government and state municipal securities. The Company has established guidelines relative to diversification and maturities that maintain safety of principal, liquidity and yield. These guidelines are periodically reviewed and modified to reflect changes in market conditions. The Company has not historically experienced any significant losses on its cash equivalents or investments. During the years ended January 31, 2019, 2018 and 2017, one vendor accounted for 21.6%, 31.3% and 33.2% of purchases, and 28.7%, 26.6% and 42.7% of accounts payable, respectively.
