At March 31, 2016, approximately $5.6 million of customer contracts and relationships is related to our oil and gas proppants segment. Under the terms of one of the contracts, the customer prepaid $15.0 million for sand, of which $12.7 million was available at March 31, 2015. This prepayment would be credited to the customer based on future sand purchases required by the contract. This customer has not made the required purchases in accordance with the terms of the contract, and therefore has forfeited approximately $10.7 million of the prepaid balance. The reversal of the $10.7 million was recorded as a reduction to cost of goods sold in our oil and gas proppants segment during fiscal 2016. We have a $2.0 million liability related to the remaining customer prepayment of sand, which is included in Other Long-Term Liabilities on the consolidated Balance Sheet. The contract terminates June 30, 2016, at which time the remaining $2.0 million will be forfeited if the customer has not placed orders for the contracted amount of sand.
