Remaining Performance Obligation

Remaining performance obligations are committed and represent non-cancellable contracted revenue that has not yet been recognized and will be recognized as revenue in future periods. Some contracts allow customers to cancel the contracts without a significant penalty, and the cancellable amount of contract value is not included in the remaining performance obligations.

The Company excludes amounts related to performance obligations and usage-based royalties that are billed and recognized as they are delivered or billed and recognized in the same period. This primarily consists of monthly usage-based runtime and hosting charges in the duration of some revenue contracts.

Revenue expected to be recognized from remaining performance obligations was approximately $465.5 million and $293.8 million as of October 31, 2021 and April 30, 2021, respectively, of which $179.4 million and $145.2 million is expected to be recognized over the next 12 months and the remainder thereafter, respectively.

Customer Concentration and Accounts Receivable

All of the Company’s customers consist of corporate and governmental entities. A limited number of customers have accounted for a large part of the Company’s revenue and accounts receivable to date. Two separate customers accounted for 28% and 11%, respectively, of revenue for the three months ended October 31, 2021. Two separate customers accounted for 16% and 13%, respectively, of revenue for the three months ended October 31, 2020. Two separate customers accounted for 25% and 12%, respectively, of revenue for the six months ended October 31, 2021. Two separate customers accounted for 17% and 12%, respectively, of revenue for the six months ended October 31, 2020. Four separate customers accounted for 16%, 15%, 14% and 12% of accounts receivable at October 31, 2021. Four separate customers accounted for 18%, 14%, 14% and 11% of accounts receivable at April 30, 2021.

Accounts receivable includes billed and unbilled receivables, net of allowance of doubtful accounts. Trade accounts receivable are recorded at invoiced amounts and do not bear interest. The expectation of collectability is based on a review of credit profiles of customers, contractual terms and conditions, current economic trends, and historical payment experience. The Company regularly reviews the adequacy of the allowance for doubtful accounts by considering the age of each outstanding invoice and the collection history of each customer to determine the appropriate amount of allowance for doubtful accounts. Accounts receivable included unbilled receivables as of October 31, 2021 and April 30, 2021 of $7.3 million and $3.8 million, respectively.
