Contract balances A receivable is recognized in the period the Company delivers goods or provides services or when the Company’s right to consideration is unconditional. The Company usually does not record contract assets because the Company has an unconditional right to payment upon satisfaction of the performance obligation, and therefore, a receivable is more commonly recorded than a contract asset. Contract liabilities include payments received in advance of performance under a contract and are satisfied as the associated revenue is recognized. Contract liabilities are reported on the consolidated balance sheets at the end of each reporting period as a component of deferred revenue. Contract liabilities as of May 31, 2022 and 2021 were $2,484,000 and $288,000, respectively. During the fiscal years ended May 31, 2022 and 2021, the Company recognized $189,000 and $164,000 of revenues that were included in contract liabilities as of May 31, 2021 and 2020, respectively. Remaining performance obligations On May 31, 2022, the Company had $212,000 of remaining performance obligations, exclusive of customer deposits, which were comprised of deferred service contracts and extended warranty contracts not yet delivered. The Company expects to recognize approximately 68% of its remaining performance obligations as revenue in fiscal 2023, and an additional 32% in fiscal 2024 and thereafter. The foregoing excludes the value of other remaining performance obligations as they have original durations of one year or less, and also excludes information about variable consideration allocated entirely to a wholly unsatisfied performance obligation. Costs to obtain or fulfill a contract The Company generally expenses sales commissions when incurred as a component of selling, general and administrative expense as the amortization period is typically less than one year. Additionally, the majority of the Company’s cost of fulfillment as a manufacturer of products is classified as inventory and fixed assets, which are accounted for under the respective guidance for those asset types. Other costs of contract fulfillment are immaterial due to the nature of the Company’s products and their respective manufacturing process.
