Receivables [Abstract] |
Accounts Receivable | Accounts receivable The majority of the Company's accounts receivable are due from geographically dispersed contractors and manufacturing companies. Credit is extended based on an evaluation of a customer's financial condition, including the availability of credit insurance. In the U.S., collateral is not generally required. In the U.A.E. and Saudi Arabia, letters of credit are usually obtained for significant orders. Accounts receivable are due within various time periods specified in the terms applicable to the specific customer and are stated at amounts due from customers net of an allowance for claims and doubtful accounts. The allowance for doubtful accounts is based on specifically identified amounts in customers' accounts, where future collectability is deemed uncertain. Management may exercise its judgment in adjusting the provision as a consequence of known items, such as current economic factors and credit trends. Past due trade accounts receivable balances are written off when the Company's collection efforts have been unsuccessful in collecting the amount due and the amount is deemed uncollectible. The write-off is recorded against the allowance for doubtful accounts. One of the Company’s accounts receivable in the total amount of $5.4 million as of January 31, 2018 (inclusive of a retention receivable amount of $3.7 million, of which $3.2 million was included in the balance of other long-term assets as of July 31, 2018 and January 31, 2018, due to the long-term nature of the receivables) has been outstanding for several years as of July 31, 2018. The Company completed all of its deliverables in 2015, and has been engaged in ongoing active efforts to collect this amount. In the second quarter of 2018, the Company received a payment of approximately $0.5 million, which reduced the balance of this receivable. As a result, the Company did not reserve any allowance against this receivable as of July 31, 2018. The Company continues to engage with the customer to ensure full payment of open balances. However, if the Company’s efforts to collect on this account are not successful in fiscal 2018, then the Company may recognize an allowance for all, or substantially all, of any such then uncollected amounts. As of July 31, 2018, this receivable balance, inclusive of a retention receivable amount, was $4.9 million. For the three months ended July 31, 2018 and 2017, one customer accounted for 13%, and no individual customer accounted for more than 10% of the Company's consolidated net sales. For the six months ended July 31, 2018 and 2017, two customers accounted for 23%, and no individual customer accounted for more than 10% of the Company's consolidated net sales. At July 31, 2018, one customer accounted for 15% of all accounts receivable. Three customers accounted for 35% of all accounts receivable at January 31, 2018.
