Transaction Price Allocated to Remaining Performance Obligations

As of September 30, 2018, the remaining performance obligations for our customer contracts with original expected durations of more than one year was $1.00 billion. We expect to recognize approximately 38.0% of our remaining performance obligations of these contracts as revenue in the next twelve months. This amount excludes agreements with consumer customers in our Hughes segment and our leasing arrangements.
