Commitments and Contingencies

Other product liabilities — We had accrued $7 and $5 for non-asbestos product liability costs at December 31, 2017 and 2016. We had also recognized $9 and $4 as expected amounts recoverable from third parties at the respective dates. The increases in the liability and recoverable amounts at December 31, 2017 largely reflect the recognition of the estimated cost, net of payments made, and the expected recovery of an insured matter. Payments made to claimants have preceded the recovery of amounts from third parties, resulting in a recoverable amount in excess of the total liability at December 31, 2017. We estimate these liabilities based on current information and assumptions about the value and likelihood of the claims against us.

Environmental liabilities — Accrued environmental liabilities were $8 at December 31, 2017 and 2016. We consider the most probable method of remediation, current laws and regulations and existing technology in estimating our environmental liabilities.

Guarantee of lease obligations — In connection with the divestiture of our Structural Products business in 2010, leases covering three U.S. facilities were assigned to a U.S. affiliate of Metalsa. Under the terms of the sale agreement, we will guarantee the affiliate’s performance under the leases, which run through June 2025, including approximately $6 of annual payments. In the event of a required payment by Dana as guarantor, we are entitled to pursue full recovery from Metalsa of the amounts paid under the guarantee and to take possession of the leased property.

Other legal matters — We are subject to various pending or threatened legal proceedings arising out of the normal course of business or operations. In view of the inherent difficulty of predicting the outcome of such matters, we cannot state what the eventual outcome of these matters will be. However, based on current knowledge and after consultation with legal counsel, we believe that any liabilities that may result from these proceedings will not have a material adverse effect on our liquidity, financial condition or results of operations.

On September 25, 2015, the Brazilian antitrust authority (“CADE”) announced an investigation of an alleged cartel involving a former Dana business in Brazil and various competitors related to sales of shock absorbers between 2000 and 2014. We divested this business as a part of the sale of our aftermarket business in 2004. The investigation of Dana's involvement in this matter concluded in the second quarter of 2016 without a material impact on Dana.

Lease commitments — Cash obligations under future minimum rental commitments under operating leases and net rental expense at December 31, 2017 are shown in the table below. Operating lease commitments are primarily related to facilities. The significant increase in lease commitments at December 31, 2017 reflects the impact of the acquisitions made during 2017. See also Note 2 for additional information about our acquisitions.
