Commitments and Contingencies From time to time, we are involved in litigation in the ordinary course of our business, including claims or contingencies that may arise related to matters occurring prior to our acquisition of businesses, such as the matter described below. At the present time, primarily because the matters are generally in early stages, we can give no assurance as to the outcome of any pending litigation to which we are currently a party and we are unable to determine the ultimate resolution of or provide a reasonable estimate of the range of possible loss attributable to these matters or the effect they may have on us. However, we do not expect the outcome of such proceedings to have a material adverse effect on our results of operations or financial condition. We have and will continue to vigorously defend ourselves against these claims. On April 23, 2013 (prior to the Polk acquisition), our CARFAX subsidiary ( CARFAX ) was served with a complaint filed in the U.S. District Court for the Southern District of New York, purportedly on behalf of certain auto and light truck dealers. The complaint alleges, among other things that, in violation of antitrust laws, CARFAX entered into exclusive arrangements regarding the sale of CARFAX vehicle history reports with certain auto manufacturers and owners of two websites providing classified listings of used autos and light trucks. The complaint seeks three times the actual damages that a jury finds the plaintiffs have sustained, injunctive relief, costs and attorneys  fees. On October 25, 2013, the plaintiffs served a second amended complaint with similar allegations purporting to name approximately 469 auto dealers as plaintiffs. The proceedings are in an early stage and there are significant legal and factual issues to be determined. We believe, however, that the probability that the outcome of the litigation will have a material adverse effect on our results of operations or financial condition is remote.
