REVENUE RECOGNITION

    DIS

    Net revenues in the Company’s DIS business accounted for over 95% of the Company’s total net revenues for the three and nine months ended September 30, 2021 and 2020 and are primarily comprised of a high volume of relatively low-dollar transactions. The DIS business, which provides clinical testing services and other services, satisfies its performance obligations and recognizes revenues primarily upon completion of the testing process (when results are reported) or when services have been rendered. The Company estimates the amount of consideration it expects to be entitled to receive from customer groups in exchange for providing services using the portfolio approach. These estimates include the impact of contractual allowances (including payer denials), and patient price concessions. The portfolios determined using the portfolio approach consist of the following groups of customers: healthcare insurers, government payers (Medicare and Medicaid programs), client payers and patients.

    For further details regarding revenue recognition in the Company's DIS business, see Note 3 to the audited consolidated financial statements in the Company's 2020 Annual Report on Form 10-K.
