Contingencies	Note 10. Contingencies Ducommun is a defendant in a lawsuit entitled United States of America ex rel Taylor Smith, Jeannine Prewitt and James Ailes v. The Boeing Company and Ducommun Inc., filed in the United States District Court for the District of Kansas (the “District Court”). The lawsuit is a qui tam action brought by three former Boeing employees (“Relators”) against Boeing and Ducommun on behalf of the United States of America for violations of the United States False Claims Act. The lawsuit alleges that Ducommun sold unapproved parts to the Boeing Commercial Airplane Group-Wichita Division which were installed by Boeing in aircraft ultimately sold to the United States Government. The number of Boeing aircraft subject to the lawsuit has been reduced to 21 aircraft following the District Court’s granting of partial summary judgment in favor of Boeing and Ducommun. The lawsuit seeks damages, civil penalties and other relief from the defendants for presenting or causing to be presented false claims for payment to the United States Government. Although the amount of alleged damages are not specified, the lawsuit seeks damages in an amount equal to three times the amount of damages the United States Government sustained because of the defendants’ actions, plus a civil penalty of $10,000 for each false claim made on or before September 28, 1999, and $11,000 for each false claim made on or after September 28, 1999, together with attorneys’ fees and costs.
