ACCOUNTS AND OTHER RECEIVABLE, NET | NOTE 9. ACCOUNTS AND OTHER RECEIVABLE, NET Accounts and other receivable are recorded at net realizable value. Components of accounts and other receivable, net of reserves, are as follows: ​

​ Amounts billed, net consist of amounts that have been invoiced to our customers in accordance with terms and conditions and are shown net of an allowance for credit losses. These receivables are all short term in nature and do not include any financing components. Unbilled receivables consist of amounts where we have satisfied our contractual obligations related to inventory stocking contracts with customers. Such amounts typically become billable to the customer upon their consumption of the inventory managed under the stocking contracts. We anticipate that substantially all unbilled receivables will be invoiced and collected over the next twelve months. These contracts do not include any financing components. The following table summarizes the changes in expected credit losses: ​
