Investments

The Company owns 50% of TerraSea Environmental Solutions (“TerraSea”) as a joint venture. TerraSea is engaged in the environmental services business through its ability to remediate contaminated soil and dredged sediment treatment. At September 30, 2016 and December 31, 2015, the Company had net advances to TerraSea of $24,898 and $27,592, respectively, which are recorded in other current assets. The Company has an accumulated deficit in joint ventures, which represents losses recognized to date in excess of our investment in TerraSea, of $14,359 and $14,271 at September 30, 2016 and December 31, 2015, respectively, which is presented in accrued expenses. The Company has commenced the wind down of TerraSea with its joint venture partner. The Company believes its net advances to TerraSea are ultimately recoverable either through the operations of the joint venture or as an obligation of our joint venture partner. The joint venture partner has notified the Company that it disagrees with the amount of net advances to TerraSea. The Company believes that its joint venture partner remains obligated for its share of net advances, and any future advances necessary to complete TerraSea’s remaining project. During July 2015, the Company proposed taking a larger percent of the loss on a TerraSea project. Based on this proposal, the Company accrued $1,506 at June 30, 2015 representing the estimated share of additional losses to be assumed. The joint venture partner and the Company are continuing discussions. If those discussions do not lead to a resolution satisfactory to both parties, the joint venture partner and the Company will go to binding arbitration as stipulated by the TerraSea operating agreement. To the extent that net advances are not fully recoverable, additional losses may result in future periods. The Company and its joint venture partner remained obligated to fund TerraSea through the completion of its remaining project. The remaining TerraSea project was substantially complete at September 30, 2016.
