We maintain an allowance for doubtful accounts based on our estimate of our ability to collect accounts receivable. The provision for uncollectible amounts was $179 million, $50 million, and $61 million for the years ended December 31, 2016, 2015 and 2014, respectively. Our allowance for doubtful accounts declined in 2015, primarily as a result of the resolution of a principal carrier dispute.  Our allowance for doubtful accounts increased in 2016 primarily as a result of the customer account balances related to the CTF Operations subsequent to the CTF Acquisition.
