____________________
(1)
The Predecessor 2016 Period includes an addition for a joint interest account receivable after a determination that future collection was doubtful.
(2)
Deductions represent the write-off of receivables and collections of amounts for which an allowance had previously been established. Deductions in 2016 are primarily due to the write-off of receivables in conjunction with a lawsuit settlement and deductions in 2015 are related to the sale of the Gulf of Mexico and Gulf Coast oil and natural gas properties.
