pre_text: The allowance for doubtful accounts represents management's estimate of uncollectible balances. We determine the allowance based on known troubled accounts, historical experience and other currently available evidence. We write off trade receivables when the likelihood of collection of a trade receivable balance is considered remote. The rollforward of allowance for doubtful accounts is as follows (in millions):
table: Year ended December 31,
table: 2019 2018 2017
table: Beginning balance $(1.3) $(1.9) $(2.2)

table: Write-offs, net of recoveries 1.6 1.2 1.1
table: Ending balance $(1.3) $(1.3) $(1.9)
