(b) | To the extent that the estimated forward loss provision exceeds accumulated contract costs it is included in the caption Other current liabilities on the Condensed Consolidated Balance Sheets. At June 30, 2017 and December 31, 2016 this amount totaled $5.1 million and $6.7 million, respectively.
(c) At June 30, 2017 and December 31, 2016, the Company has $109.9 million and $101.1 million, respectively, of customer advances related to contracts-in-process. These amounts are included in the caption Advances on contracts and other customer advances on the Condensed Consolidated Balance Sheets. The Company recognized an estimated forward loss provision related to the contracts with the federal railway system of Switzerland ("SBB") of $45.1 million, for the year ended December 31, 2016 in Costs of products sold on the Condensed Consolidated Statements of Operations, of which $40.1 million was recognized during the three and six months ended June 30, 2016. There was no additional estimated forward loss provision recognized, excluding the impact of foreign currency fluctuation, for the three and six months ended June 30, 2017. The estimated forward loss provision represents the Company's best estimate based on currently available information. It is possible that the Company's overall estimate of costs to complete these contracts may increase, which would result in an additional estimated forward loss provision at such time, but the Company is unable to estimate any further possible loss or range of loss at this time. The Company did not recognize any revenue for the contracts with SBB for the three and six months ended June 30, 2017 and 2016 under the percentage-of-completion (units-of-delivery) method and accordingly, there was no impact on the Company's gross margins or results of operations for these periods. The Company has not yet recognized any revenue associated with the major equipment deliveries under the contracts with SBB. The majority of the equipment deliveries and related revenue recognition under these contracts are expected through 2020.
