Legal Matters	11. Legal Matters On February 5, 2013, the Company was notified by one of its customers that certain product purchased by that customer had quality issues. On March 11, 2013, the Company and the customer entered into an agreement whereby the Company will reimburse the customer for reasonable costs and expenses incurred on or before December 31, 2013 by the customer in its efforts to resolve the quality issue. At December 31, 2012 and May 31, 2013, the Company recorded a liability and expense of $50,000 and approximately $102,000, respectively, for estimated costs to be reimbursed to the customer pursuant to the terms of the agreement. As of June 30, 2013, the balance of this liability, which is included in accounts payable, was approximately $10,000. The Company has no current obligation to reimburse the customer for costs incurred after December 31, 2013 and has in place liability coverage for third-party injury and property damage that might occur as a result of the product’s quality issue. In February 2013, a customer brought legal action against the Company alleging the Company defaulted on its obligations and failed to perform pursuant to the terms of a written agreement entered into with the Company in February 2012. The customer sought to recover its damages in an unspecified sum and liquidated damages in the amount of $50,000 as well as costs and fees. In April 2013, the customer and the Company agreed to a settlement of the customer’s claims pursuant to which the Company will pay to the customer an aggregate amount of $30,000. Under terms of the settlement agreement, the Company will make five monthly payments of $6,000 to the customer which began May 1, 2013. At March 31, 2013, the Company recorded an expense of $30,000 related to this settlement, of which $18,000 remained unpaid and outstanding and is included in accrued settlement as of June 30, 2013. In March 2012, the Company was named as a defendant in a legal action brought by a competitor (which was also a former customer and supplier) who alleged that the Company and certain other third-party defendants profited improperly from the use of intellectual property developed by the competitor. The Company had consistently believed that the asserted claims were without merit and that the Company’s chances of prevailing without material liability were high. However, due largely to the increasing costs of the ongoing litigation, the Company and the plaintiff entered into a settlement agreement effective as of June 12, 2013 (the “Settlement Agreement”). Pursuant to terms of the Settlement Agreement, the parties agreed, among other things, that the Company would pay to the plaintiff all outstanding invoices due to the plaintiff as of the date of the settlement, net of existing amounts due to the Company from the plaintiff, and would pay license, service and other fees to the plaintiff in return for the plaintiff’s providing maintenance services on lockers distributed to certain of the Company’s customers. At March 31, 2013, the Company recorded an expense of approximately $412,000 related to the settlement. Of this amount, approximately $377,000 was recorded as accrued settlement and approximately $35,000 was included in other accrued expenses at March 31, 2013. The Company will pay amounts due to the plaintiff under the terms of the Settlement Agreement over a minimum period of 29 months which began June 1, 2013. The Company is involved in other claims and litigation from time to time in the normal course of business. The Company does not believe these matters will have a significant adverse impact on the Company’s operations or financial condition.
