At June 30, 2017, the owners of 52.5% of the equity not owned by DXP included a former executive officer and other employees of DXP. Equity investments in which we exercise significant influence, but do not control and are not the primary beneficiary, are accounted for using the equity method of accounting. During the first quarter of 2016, DXP invested $4.0 million in a related party equity method investment. During the third and fourth quarters of 2016, the investment was reduced to zero by $4.0 million of distributions received from the entity. All intercompany accounts and transactions have been eliminated upon consolidation.
