Concentration of Risk
Note 18—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.
 
During the years ended January 31, 2020, 2019 and 2018, one vendor accounted for 21.2%, 21.6% and 31.3% of purchases, and 28.0%, 28.7% and 26.6% of accounts payable, respectively, as of January 31, 2020, 2019 and 2018.
