The Company’s financing receivables, consisting of its accounts receivable with contractual maturities of more than one year, totaled $3.8 million and $4.3 million at June 30, 2020 and 2019, respectively, and are included in Other Assets in the consolidated balance sheets.

The Company evaluates the credit quality of an obligor at contract inception and monitors credit quality over the term of the underlying transactions. The Company performs a credit analysis for all new customers and reviews payment history, current order backlog, financial performance of the customers and other variables that augment or mitigate the inherent credit risk of a particular transaction. Such variables include the underlying value and liquidity of the collateral, the essential use of the equipment, the contract term and the inclusion of credit enhancements, such as guarantees, letters of credit or security deposits. The Company classifies accounts as high risk when it considers the financing receivable to be impaired or when management believes there is a significant near‑term risk of non‑payment.

Based upon such assessment, the Company recorded adjustments of $0.8 million and $3.6 million to the allowance for credit losses related to such financing receivables during the years ended June 30, 2020 and 2019, respectively.
