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 which is included in “Prepaid expenses and other current assets” due to its short-term nature. During the third quarter of 2016, the investment was reduced by $0.8 million of distributions received from the investment. A portion of the remaining interest in this investment is owned by the Company’s Chief Executive Officer. All intercompany accounts and transactions have been eliminated upon consolidation.
