Change in ownership interests in Asia Pacific joint venture

On August 1, 2016, the Company consummated an agreement with Khazanah Nasional Berhad (Khazanah) and Mitsui and Co., Ltd (Mitsui) whereby Khazanah and Mitsui subscribed to invest a total of $300,000 over three years in exchange for a 40% total equity interest in the Company’s APAC JV. Khazanah and Mitsui each made related initial investments of $50,000 in this business on August 1, 2016.

Based on the governance structure and voting rights put in place upon the formation of the APAC JV, certain key decisions affecting the JV’s operations are no longer at the unilateral discretion of the Company, but rather are shared with the noncontrolling investors. As a result, the Company deconsolidated its Asia Pacific dialysis business in the third quarter and recognized a non-cash non-taxable gain of $374,374 on its retained investment, net of contingent obligations. This retained interest was adjusted to the Company’s proportionate share of the estimated fair value of the business, as implied by the Khazanah and Mitsui investment and adjusted for certain time value of money and uncertainty discounts. Subsequent to the deconsolidation, the Company’s retained interest in the APAC JV is accounted for under the equity method.

The calculation of the Company’s non-cash gain on its retained investment in the APAC JV is based upon the best information available to management and will be finalized when certain information arranged to be obtained has been received, including issuance of the final valuation report by an independent third party and certain post-closing adjustments subject to audit of the APAC JV’s financial statements.

Sales of Tandigm Health and DMG Arizona ownership interests

Effective June 30, 2016, the Company sold a portion of DMG’s ownership interest in the Tandigm Health (Tandigm) joint venture, reducing its ownership from fifty percent to nineteen percent and resulting in a gain of $40,280. In addition, on June 1, 2016, the Company sold its DMG Arizona business, resulting in a loss of $10,489.

Acquisition of TEC

On March 1, 2016, the Company completed its acquisition of The Everett Clinic (TEC) pursuant to an agreement and plan of merger dated November 23, 2015, whereby TEC became a 100% consolidated subsidiary of DMG. TEC has 500 providers in primary and specialty care locations throughout Snohomish County, Washington who care for more than 315,000 patients. The total consideration paid at closing for all outstanding common units of TEC was approximately $393,687, net of cash acquired, plus the assumption of certain liabilities totaling approximately $7,284.

The initial purchase price allocation for the acquisition of TEC is recorded at estimated fair values based upon the best information available to management and will be finalized when certain information arranged to be obtained has been received. The fair values of property and equipment and intangible assets were valued by an independent third party and are pending issuance of the final valuation report. Certain income tax amounts are pending issuance of final tax returns.

The following table summarizes the assets acquired and liabilities assumed in this transaction and recognized at the acquisition date at their estimated fair values:

Current assets, net of cash acquired	$	91,591

Amortizable intangible assets acquired in this acquisition have a weighted average estimated useful life of six years. None of the goodwill recognized in this acquisition is expected to be deductible for tax purposes.

The noncontrolling interests assumed as part of the acquisition are stated at estimated fair value based on the estimated fair value of the underlying assets and liabilities of each non-wholly-owned entity.

The operating results of TEC are included in the Company’s consolidated financial statements from March 1, 2016.

Other pending transactions

On August 9, 2016, the Company entered into an amendment to its agreement to acquire Colorado-based Renal Ventures Limited, LLC (Renal Ventures). As a result of the amended agreement, the Company will acquire a 100 percent interest in all 38 outpatient dialysis centers owned by Renal Ventures, including one new center under construction, and a fifty-one percent interest in one vascular access clinic.

Contingent earn-out obligations

The Company has several contingent earn-out obligations associated with acquisitions that could result in the Company paying the former shareholders of acquired companies a total of up to approximately $19,557 if certain EBITDA, operating income performance targets or quality margins are met over the next one to eight years.

Contingent earn-out obligations are remeasured to fair value at each reporting date until the contingencies are resolved with changes in the liability due to the remeasurement recorded in earnings. See Note 24 to these consolidated financial statements for further details.
