4. | ACCOUNTS RECEIVABLE, TRANSIT ACCOUNTS RECEIVABLE AND TRANSIT ACCOUNTS PAYABLE
The Company ’s accounts receivable are comprised as follows:
|  | December 30, 2017 |  |  | December 31, 2016 |
Billed |  | $ | 31,448 |  |  | $ | 34,463 |
Accrued and unbilled |  |  | 10,573 |  |  |  | 6,894 |
Work-in-progress |  |  | 5,026 |  |  |  | 5,215 |
Allowance for sales discounts and doubtful accounts |  |  | (967 | ) |  |  | (1,402 | )
Accounts receivable, net |  | $ | 46,080 |  |  | $ | 45,170 |
Unbilled receivables primarily represent revenues earned whereby those services are ready to be billed as of the balance sheet ending date. Work-in-pro gress primarily represents revenues earned under contracts which the Company contractually invoices at future dates. The Company has a dispute with a customer that is a major utility in the United States. Essentially, the customer has not paid the balance of accounts receivable the Company believes are owed to the Company. The Company recently compelled arbitration with this customer. The total amount due from this customer is $6.9 million, subject to an upward adjustment following disclosures by the customer in the arbitration. Additionally, as part of the arbitration process, the customer has asserted counter claims of $9.3 million. The Company also believes these counter claims were retaliatory in nature. Prior to the arbitration, the customer had not asserted any claims. The Company believes these asserted claims have no merit and were merely asserted as a strategy to reduce the Company’s claims in any arbitration award or potential settlement agreement. The Company believes that its accounts receivable balance, subject to reserves, is collectible. Furthermore, the Company believes that this arbitration will conclude sometime in fiscal year 2018. While the Company believes the customer’s counter claims to be frivolous and without merit, it can give no assurances that it will ultimately not have to pay all or a portion of such claims.
