| (4) | Receivables and Allowance for Credit Losses
|  | Receivables consist of the following (in thousands):
|  | December 31, |
|  | 2020 |  |  | 2019 |
Accounts receivable–trade |  | $ | 26,912 |  |  | $ | 29,134 |
Less allowance for credit losses |  |  | (484 | ) |  |  | (486 | )
Receivables, net |  | $ | 26,428 |  |  | $ | 28,648 |
|  | Effective January 1, 2020, the Company adopted ASU 2016-13, Financial Instruments – Credit Losses (ASC 326) which is required to be applied by means of a cumulative-effect adjustment to the opening retained earnings balance as of the adoption date. This ASU replaces the incurred loss impairment model with an expected credit loss impairment model for financial instruments, including trade receivables and contract assets. The amendment requires entities to consider forward-looking information to estimate expected credit losses, resulting in earlier recognition of losses for receivables that are current or not yet due, which were not considered under the previous accounting guidance. There was no impact to the Company’s opening retained earnings or its consolidated balance sheet upon adoption and as a result, the balances presented for December 31, 2019, which were derived under the incurred loss model are comparable to December 31, 2020.
|  | The Company is exposed to credit losses primarily through sales of products and services. The Company’s expected loss allowance methodology for accounts receivable is developed using historical collection experience, current and future economic and market conditions, and a review of the current status of customers' trade accounts receivables. Due to the short-term nature of such receivables, the estimate of the amount of accounts receivable that may not be collected is based on aging of the accounts receivable balances. Additionally, specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default due, in part, to their financial condition. The Company’s monitoring activities include timely account reconciliation, dispute resolution, payment confirmation, consideration of customers' financial condition and macroeconomic conditions. Balances are written off when determined to be uncollectible. Estimates based on an assessment of anticipated payment and all other historical, current and future information that is reasonably available are used to determine the allowance.
|  | The following table provides a roll-forward of the allowance for credit losses that is deducted from accounts receivable to present the net amount expected to be collected for the years ended December 30, 2020 and 2019 (in thousands):
