Trade Accounts Receivable	(4) Trade Accounts Receivable The allowance for doubtful accounts, which was $1.7 million and $0.8 million as of December 31, 2018 and 2017, respectively, is our best estimate of the amount of probable credit losses included in our existing accounts receivable. During the year ended December 31, 2018, we increased our allowance for doubtful accounts by $0.9 million, due primarily to estimated uncollectible amounts from customers of the USA Compression Predecessor. The USA Compression Predecessor reduced its allowance for doubtful accounts by $4.1 million and $1.0 million during the years ended December 31, 2017 and 2016, respectively, due to write-offs of receivables and collections on accounts previously reserved. Due to the decrease in the allowance for doubtful accounts during 2017 and 2016, the USA Compression Predecessor recognized a reduction of bad debt expense of $1.8 million and $0.6 million for the years ended December 31, 2017 and 2016, respectively.
