Remaining performance obligations are comprised of deferred revenues and unbilled contract revenues that will be invoiced and recognized as revenues in future periods primarily related to value added services. As of September 30, 2021, the remaining performance obligations were $1.7 billion. The Company expects approximately half to be recognized as revenue in the next two years and the remaining thereafter. However, the amount and timing of revenue recognition is affected by several factors, including contract modifications and terminations, which could impact the estimate of amounts allocated to remaining performance obligations and when such revenues could be recognized.
