Grants from Outside Parties

The Company periodically receives grants for the upgrade and construction of rail lines and the upgrade of locomotives from federal, provincial, state and local agencies in the United States and provinces in Canada in which the Company operates. These grants typically reimburse the Company for 50% to 100% of the actual cost of specific projects. In total, the Company received grant proceeds of $16.2 million and $16.4 million for the three months ended March 31, 2016 and 2015, respectively, from such grant programs. The proceeds were presented as cash inflows from investing activities within each of the applicable periods.

None of the Company's grants represent a future liability of the Company unless the Company abandons the rehabilitated or new track structure within a specified period of time or fails to maintain the upgraded or new track to certain standards, fails to make certain minimum capital improvements or ceases use of the locomotives within the specified geographic area and time period, in each case, as defined in the applicable grant agreement. As the Company intends to comply with the requirements of these agreements, the Company has recorded additions to track property and locomotives and has deferred the amount of the grants. The amortization of deferred grants is a non-cash offset to depreciation expense over the useful lives of the related assets.

The following table sets forth the offset to depreciation expense from the amortization of deferred grants recorded by the Company during the three months ended March 31, 2016 and 2015 (dollars in thousands):

Insurance and Third-Party Claims

Accounts receivable from insurance and other third-party claims at March 31, 2016 included $12.8 million from the Company's North American Operations, $6.2 million from the Company's Australian Operations and $6.1 million from the Company's U.K./European Operations. The balance from the Company's North American Operations resulted predominately from the Company's anticipated insurance recoveries associated with a derailment in Alabama (the Aliceville Derailment) in November 2013. The balance from the Company's Australian Operations resulted primarily from the Company's anticipated insurance recoveries associated with derailments in Australia in 2012. The balance from the Company's U.K./European Operations resulted primarily from the Company's anticipated insurance recoveries associated with a rail-related collision in Germany in 2014 that occurred prior to the Company's acquisition of Freightliner. The Company received proceeds from insurance totaling $2.4 million and $1.4 million for the three months ended March 31, 2016 and 2015, respectively.
