This amount was previously recorded as a reduction to revenue in prior periods during the contract term. Adjusted net revenue is a non-GAAP financial measure. Therefore, it should not be considered a substitute for net revenue prepared in accordance with U.S. GAAP and may not be comparable to similarly titled measures used by other companies. Management believes adjusted net revenue is meaningful as it excludes the impact of a non-recurring revenue adjustment related to the release of a liability associated with our original Medicare RAC contract, which expired on January 31, 2018. b) 3 Total Global Retail and Other Consolidated Net Revenue $ 15,748 177,453 $ -15,74816,052(2) 600176,853$ 167,6116 % % 34,411-34,41136,382(5) % $ 396,487 $47,156$349,331$327,7447 % 362,07647,156314,920291,3628 % 161,705600161,105151,5596 % Total Healthcare Six Months Ended June 30, 20182017 Adjusted NetNetNet RevenueAdjustment(a) Revenue(b) RevenueChange Three Months Ended June 30, 20182017 Adjusted NetNetNet RevenueAdjustment(a) Revenue(b) RevenueChange (unaudited, $ in thousands) Adjusted Net Revenue(b)$ 176,853$ 167,6116 % $ 349,331$ 327,7447 % $ 396,487$327,74421 % Net Revenue$ 177,453$167,6116 % Six Months Ended June 30, 20182017Change Three Months Ended June 30, (unaudited, $ in thousands)20182017Change

Cotiviti Holdings, Inc. Cash Flow Data Operating Cash Flow Capital Expenditures $ 78,714 21,213 $ 42,300 16,593 a) Free cash flow is a non-GAAP financial measure. Therefore, it should not be considered a substitute for income or cash flow data prepared in accordance with U.S. GAAP and may not be comparable to similarly titled measures used by other companies. The Company defines free cash flow as net cash provided by operating activities less capital expenditures. It should not be inferred that the entire free cash flow amount is available for discretionary expenditures. Management believes free cash flow is meaningful as it is used by management and investors as a measure and indicator of the financial strength of the company and its ability to generate cash. 7 Repurchase of Common Stock $-$-$57,501$25,707 Free Cash Flow(a) Six Months Ended June 30, 20182017 (unaudited, $ in thousands)
