Revenue from Contract with Customer [Abstract]

REVENUE RECOGITION

DIS

Net revenues in the Company’s DIS business accounted for over 95% of the Company’s total net revenues for the three months ended March 31, 2019 and 2018 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 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, determined using the portfolio approach, in exchange for providing services. These estimates include the impact of contractual allowances, including payer denials, and price concessions. The portfolios determined using the portfolio approach consist of the following groups of customers: healthcare insurers, government payers, client payers and patients.

The Company’s DS businesses primarily satisfy their performance obligations and recognize revenues when delivery has occurred or services have been rendered.

The approximate percentage of net revenue by type of customer was as follows:
