At March 31, 2019, we had an immaterial amount of contract assets resulting from revenue being recognized in excess of the amount that we have the right to invoice the customer.

Revenue allocated to remaining performance obligations represents non-cancellable contracted revenue that has not yet been recognized, which includes unearned revenue and amounts that will be delivered and recognized as revenue in future periods. Contracted, but not recognized, revenue was $29.0 million as of March 31, 2019, of which we expect to recognize approximately 54% over the next 12 months and the remainder thereafter. We applied the practical expedient provided under the revenue recognition standard and have not included information about remaining performance obligations that have original expected duration of one year or less.
