Remaining Performance Obligations

For transaction prices allocated to remaining performance obligations, we apply practical expedients and do not disclose quantitative or qualitative information for remaining performance obligations (i) that have original expected durations of one year or less and (ii) where we recognize revenue equal to what we have the right to invoice and that amount corresponds directly with the value to the customer of our performance to date.

We have remaining performance obligations of $8.4 million attributable to Implied Maintenance Release PCS recorded in deferred revenue as of December 31, 2020. We expect to recognize revenue for these remaining performance obligations of $3.4 million, $2.1 million, $1.4 million, $0.9 million, and $0.5 million for the years ended December 31, 2021, 2022, 2023, 2024, and 2025, respectively, and $0.1 million thereafter.
