(a)  Subsequent to the adoption of ASC 606, the majority of what was previously presented as allowance for doubtful accounts related to bad debt expense has been incorporated as an implicit price concession factored into net revenue and accounts receivable. Allowance for doubtful accounts as of December 31, 2019 represents the Company’s best estimate of probable losses inherent in the accounts receivable balance based on known troubled accounts and other currently available evidence.
