Noncontrolling Interest

3 Months Ended

Mar. 31, 2018

As of March 31, 2018, we have 5 VIEs included in our consolidated financial statements all of which are NxStage Kidney Care dialysis centers. We are the managing member or we have a majority seat on the entity’s board of managers, manage these entities through a management services agreement.

The analysis upon which these consolidation determinations rest are complex, involve uncertainties, and require significant judgment on various matters. At March 31, 2018 and December 31, 2017, total assets of our VIEs were $6.7 million and $5.6 million, and total liabilities and noncontrolling interests of our VIEs were $6.6 million and $5.8 million, respectively.

We have potential obligations to purchase the noncontrolling interests held by third parties in certain of our consolidated subsidiaries. These obligations are in the form of put provisions and are contingently exercisable at the third-party owners' discretion given specific facts and circumstances as outlined in each specific put provision. If these put provisions were exercised, we would be required to purchase all the third-party owners' noncontrolling interests at a fair value at the time of exercise pursuant to the terms of the agreement. At March 31, 2018 the Company's noncontrolling interests subject to put provisions were $(0.2) million and none of the rights were exercisable.

The following table sets forth the changes in noncontrolling interest not subject to put provisions for the three months ended March 31, 2018 and 2017 (in thousands):
