15. COMMITMENTS AND CONTINGENT LIABILITIES

From time-to-time, we are a party to ordinary, routine litigation arising in the ordinary course of business, most of which involves claims for personal injury and property damage incurred in connection with the transportation of freight. We maintain insurance to cover liabilities arising from the transportation of freight for amounts in excess of certain self-insured retentions. In management's opinion, our potential exposure under pending legal proceedings is adequately provided for in the accompanying consolidated financial statements.

On August 26, 2014, the U.S. District Court for the Southern District of Ohio issued a pre-trial decision in a lawsuit against SRT relating to a cargo claim incurred in 2008. The court awarded the plaintiff approximately $5.9 million plus prejudgment interest and costs and denied a cross-motion for summary judgment by SRT. Previously, the court had ruled in favor of SRT on all but one count before overturning its earlier decision and ruling in favor of the plaintiff. SRT filed a Notice of Appeal with the U.S. Sixth Circuit Court of Appeals on September 24, 2014 and that appeal is currently being briefed by the parties with oral arguments to be scheduled in the months ahead. As a result of this decision and pending final outcome of the appeal, we increased the reserve for this claim by approximately $7.5 million to approximately $8.1 million during the third quarter of 2014.

We had $34.3 million and $39.0 million of outstanding and undrawn letters of credit as of December 31, 2014 and 2013, respectively. The letters of credit are maintained primarily to support our insurance programs.

Effective April 2013, we entered into an auto liability policy with a three-year term. The policy retains the $1.0 million per claim limit for the primary excess layer of our auto liability program, with no changes to the excess policies. Similar to the prior policy, the current policy contains a commutation option; however, this option is only available after the completion of the three-year policy term, unless both we and the insurance carrier agree to a commutation prior to the end of the policy term.
