transportation and storage costs incurred under these agreements totaled $ 140.5 million , $ 135.1 million and $ 137.7 million for the years ended december 31 , 2017 , 2016 and 2015 , respectively . these amounts do not include contractual commitments under our long-term transportation agreements with hep , as all transactions with hep are eliminated in these consolidated financial statements . we have a crude oil supply contract that requires the supplier to deliver a specified volume of crude oil or pay a shortfall fee for the difference in the actual barrels delivered to us less the specified barrels per the supply contract . for the contract year ended august 31 , 2017 , the actual number of barrels delivered to us was substantially less than the specified barrels , and we recorded a reduction to cost of goods sold and accumulated a shortfall fee receivable of $ 26.0 million during this period . in september 2017 , the supplier notified us they are disputing the shortfall fee owed and in october 2017 notified us of their demand for arbitration . we offset the receivable with payments of invoices for deliveries of crude oil received subsequent to august 31 , 2017 , which is permitted under the supply contract . we believe the disputes and claims made by the supplier are without merit . in march , 2006 , a subsidiary of ours sold the assets of montana refining company under an asset purchase agreement ( 201capa 201d ) . calumet montana refining llc , the current owner of the assets , has submitted requests for reimbursement of approximately $ 20.0 million pursuant to contractual indemnity provisions under the apa for various costs incurred , as well as additional claims related to environmental matters . we have rejected most of the claims for payment , and this matter is scheduled for arbitration beginning in july 2018 . we have accrued the costs we believe are owed pursuant to the apa , and we estimate that any reasonably possible losses beyond the amounts accrued are not material . note 20 : segment information effective fourth quarter of 2017 , we revised our reportable segments to align with certain changes in how our chief operating decision maker manages and allocates resources to our business . accordingly , our tulsa refineries 2019 lubricants operations , previously reported in the refining segment , are now combined with the operations of our petro-canada lubricants business ( acquired february 1 , 2017 ) and reported in the lubricants and specialty products segment . our prior period segment information has been retrospectively adjusted to reflect our current segment presentation . our operations are organized into three reportable segments , refining , lubricants and specialty products and hep . our operations that are not included in the refining , lubricants and specialty products and hep segments are included in corporate and other . intersegment transactions are eliminated in our consolidated financial statements and are included in eliminations . corporate and other and eliminations are aggregated and presented under corporate , other and eliminations column . the refining segment represents the operations of the el dorado , tulsa , navajo , cheyenne and woods cross refineries and hfc asphalt ( aggregated as a reportable segment ) . refining activities involve the purchase and refining of crude oil and wholesale and branded marketing of refined products , such as gasoline , diesel fuel and jet fuel . these petroleum products are primarily marketed in the mid-continent , southwest and rocky mountain regions of the united states . hfc asphalt operates various asphalt terminals in arizona , new mexico and oklahoma. .
