On January 5, 2018, we entered into a definitive agreement to sell our Mexican asphalt business for $55 million in cash plus or minus non-cash working capital as of closing (subject to customary adjustments for capital expenditures). At December 31, 2017, the assets and liabilities of the Mexican asphalt business are reflected on the consolidated balance sheet as held for sale and have been written down to net realizable value by recording an impairment of $13.5 million, including the impact of a deferred foreign currency translation loss of $30.9 million. We expect the sale to close in the second quarter of 2018. The proceeds from the disposal will be used to repay debt. The Mexican asphalt business contributed a pre-tax loss of $8.2 million for the year-ended December 31, 2017, including the write-down to net realizable value. At December 31, 2017, the Mexican assets and liabilities held for sale included $29.4 million of property, plant and equipment, $34.9 million of current assets and $19.4 million of current liabilities.

On February 23, 2018, we entered into an agreement to sell our U.K. operations, SemLogistics, for an estimated $71.5 million. In addition to the sale price, the agreement provides for potential earnout payments to be made to SemGroup if certain revenue targets are met in the four years following close of the transaction. SemGroup intends to use proceeds from the sale toward its capital raise plan and to pre-fund capital growth projects. The sale is expected to close by the end of the third quarter of 2018.

At December 31, 2017, the assets and liabilities of our storage and terminalling business in the U.K. are reflected on the consolidated balance sheet as held for sale and have been written down to net realizable value by recording an impairment of $76.7 million, including the impact of a deferred foreign currency translation loss of $22.8 million. Net realizable value was estimated at $71.5 million less working capital adjustments and costs to sell. The U.K. business contributed a pre-tax loss of $73.0 million for the year-ended December 31, 2017, including the write-down to net realizable value. At December 31, 2017, the U.K. assets and liabilities held for sale included $136.8 million of property, plant and equipment, $3.1 million of current assets and $4.4 million of current liabilities.

At December 31, 2017, we recorded a $31.0 million impairment of our Sherman, Texas natural gas gathering and processing assets of our SemGas segment. Evaluation of capital raising alternatives indicated that the carrying value of our Sherman, Texas assets might be in excess of fair value. We compared the forecasted undiscounted cash flows for the assets to the carrying value of the assets, which indicated that the carrying value of assets was impaired. We used an income approach based on a discounted cash flow model to estimate the fair value of the assets and recorded a non-cash impairment.

Impairments are based on unobservable inputs and considered to be Level 3 measurements. See Note 6 for discussion of the sale of our equity method investment in Glass Mountain. See Note 11 for discussion of impairment of goodwill and finite-lived intangible assets recorded by our Crude Transportation segment.
