Fiscal 2018

The increase in the Medical segment goodwill during fiscal 2018 is primarily due to the Patient Recovery Business acquisition. Goodwill recognized in connection with the Patient Recovery Business acquisition primarily represents the expected benefits from certain synergies of integrating the business, the existing workforce of the acquired entity, and the expected growth from new customers. See Note 2 for further discussion of this acquisition.

In conjunction with the preparation of our consolidated financial statements for fiscal 2018, we completed our annual quantitative goodwill impairment test, which we perform annually in the fourth quarter. Using a combination of income and market-based approaches (using a discount rate of 8.5 percent), the carrying value exceeded the fair value and resulted in an impairment charge of $1.4 billion related to our Medical Unit, which is included in impairments and loss on disposal of assets in our consolidated statements of earnings. Our fair value estimates utilize significant unobservable inputs and thus represent Level 3 fair value measurements.

The impairment was primarily driven by inventory and cost challenges within our Cordis business which furthered in the fourth quarter of fiscal 2018. This impairment charge did not impact our liquidity, cash flows from operations, or compliance with debt covenants. There was no tax benefit related to the goodwill impairment charge. The goodwill balance for our Medical Unit, after recognizing the impairment, was $4.3 billion at June 30, 2018.

During fiscal 2018, goodwill was also reduced by $401 million and $509 million in connection with the sale of our China distribution business and reclassification of naviHealth's assets and liabilities to held for sale, respectively.

See Note 2 for further discussion of this divestiture and assets held for sale.
