Collection Matter In December 2011, our wholly owned subsidiary, Spectrum Design Services, Inc., brought claims against Iota, Inc. (“Iota”) and Corsair Engineering, Inc. (“Corsair”) in Minnesota State District Court. The claims were made to collect unpaid receivables from Iota that are subject to a payment guaranty from Corsair. These claims arose out of a contract between Iota and Spectrum for the development of a custom product for Iota. Spectrum ceased work on the project for non-payment of invoices before making its claims. During our second quarter of fiscal 2012, Iota and Corsair removed the cases to Federal District Court in Minnesota and Iota asserted counterclaims against Spectrum for breach of contractual warranty, breach of contract and negligent misrepresentation. The counterclaims alleged damages for recovery of over $300,000 previously paid by Iota to Spectrum as well as lost profits and other damages. In connection with the mediation completed on June 29, 2012, we, Iota and Corsair signed an agreement to dismiss all claims related to this matter and reached a settlement on the unpaid receivable. The settlement did not have a material impact to us. In addition to the matters discussed above, in the normal course of business, we are subject to various claims and litigation, which may include, but are not limited to, patent infringement and intellectual property claims. Our management expects that these various claims and litigation will not have a material adverse effect on our consolidated results of operations or financial condition.
