Investments [Abstract]
Investments	6. Investments Investments in non-marketable equity securities are accounted for under the fair value, equity or net asset value method of accounting and are included in investments in the condensed consolidated balance sheets. For equity securities without a readily determinable fair value, we use the fair value measurement alternative and measure the securities at cost less impairment, if any, including adjustments for observable price changes in orderly transactions for an identical or similar investment of the same issuer. For investments in which we can exercise significant influence but do not control, we use the equity method of accounting. Our share of the earnings and losses are recorded in other income, net in the condensed consolidated statements of earnings. We closely monitor our investments for other-than-temporary impairment by considering factors such as the operating performance of the investment and current economic and market conditions. In connection with the naviHealth divestiture discussed in Note 4, we obtained a 44 percent equity interest in a partnership that owns 100 percent of the equity interest of naviHealth. We accounted for this investment initially at its fair value using Level 3 unobservable inputs based on expected sales proceeds following a competitive bidding process. Accordingly, we initially recognized a $358 million equity method investment during the three months ended September 30, 2018. We are accounting for this investment using the equity method of accounting and on a one-month reporting lag. Our proportionate share of naviHealth's net loss for the three months ended September 30, 2018 was immaterial. Our proportionate share includes only one month of naviHealth's results due to the divestiture occurring in August and as a result of the one-month reporting lag. During the three months ended September 30, 2018 we received a non-cash distribution of $14 million in the form of the partnership's payment for certain of our divestiture transaction costs directly to the applicable third-party. At September 30, 2018 the carrying value of this investment was $344 million.

Investments in non-marketable equity securities are accounted for under the fair value, equity or net asset value method of accounting and are included in investments in the condensed consolidated balance sheets. For equity securities without a readily determinable fair value, we use the fair value measurement alternative and measure the securities at cost less impairment, if any, including adjustments for observable price changes in orderly transactions for an identical or similar investment of the same issuer. For investments in which we can exercise significant influence but do not control, we use the equity method of accounting. Our share of the earnings and losses are recorded in other income, net in the condensed consolidated statements of earnings. We closely monitor our investments for other-than-temporary impairment by considering factors such as the operating performance of the investment and current economic and market conditions.

In connection with the naviHealth divestiture discussed in Note 4, we obtained a 44 percent equity interest in a partnership that owns 100 percent of the equity interest of naviHealth. We accounted for this investment initially at its fair value using Level 3 unobservable inputs based on expected sales proceeds following a competitive bidding process. Accordingly, we initially recognized a $358 million equity method investment during the three months ended September 30, 2018.

We are accounting for this investment using the equity method of accounting and on a one-month reporting lag. Our proportionate share of naviHealth's net loss for the three months ended September 30, 2018 was immaterial. Our proportionate share includes only one month of naviHealth's results due to the divestiture occurring in August and as a result of the one-month reporting lag. During the three months ended September 30, 2018 we received a non-cash distribution of $14 million in the form of the partnership's payment for certain of our divestiture transaction costs directly to the applicable third-party. At September 30, 2018 the carrying value of this investment was $344 million.
