Commitments And Contingencies	8. Commitments and Contingencies: Legal Actions In April 2009, the Company received notice that the receiver for two companies that filed for the Italian law equivalent of bankruptcy protection in May 2004, Finmek Manufacturing SpA and Finmek Access SpA (collectively, the “Finmek Companies”), had filed a lawsuit under an Italian “claw back” law in Padua, Italy against the Company, seeking the return of approximately $16.7 million in payments received by the Company in the ordinary course of business for components sold by the Company to the Finmek Companies prior to the bankruptcy filing. The Finmek Companies were among Enel’s third party meters manufacturers, and from time to time through January 2004, the Company sold components to the Finmek Companies that were incorporated into the electricity meters that were manufactured by the Finmek Companies and sold to Enel SpA for the Enel Project. The Company believed that the Italian claw back law was not applicable to its transactions with the Finmek Companies, and the claims of the Finmek Companies’ receiver were without merit. However, it was brought to the Company's attention that a substantial percentage of claw back cases reviewed by the local courts, which are located in the jurisdiction in which the Finmek Companies were headquartered, were being decided in favor of the Finmek Companies. To avoid any possibility of an adverse ruling against the Company, as well as to limit administrative inconvenience and curtail litigation costs, in April 2013, with the consent of its Board of Directors, the Company decided to settle this matter. The Company reached an agreement with respect to a financial settlement of $3.5 million and recognized a charge for this amount in the first quarter of 2013. This settlement was formalized and became effective in the fourth quarter of 2013, to be paid in two substantially equal installments, one in the fourth quarter of 2013 and the other in the fourth quarter of 2014. The Company did not admit that the Italian claw back law applied to its circumstances as part of this settlement. From time to time, in the ordinary course of business, the Company may be subject to other legal proceedings, claims, investigations, and other proceedings, including claims of alleged infringement of third-party patents and other intellectual property rights, and commercial, employment, and other matters. In accordance with generally accepted accounting principles, the Company makes a provision for a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. While the Company believes it has adequately provided for such contingencies as of September 30, 2014, the amounts of which were immaterial, it is possible that the Company’s results of operations, cash flows, and financial position could be harmed by the resolution of any such outstanding claims. Line of Credit The Company maintains a $5.0 million secured line of credit with its primary bank, which expires on July 1, 2015. The line of credit is secured by a collateral of first priority on $6.3 million of the Company's investment balance placed in a separate account (presented as restricted investments in the condensed consolidated balance sheets). The line of credit contains certain financial covenants requiring the Company to maintain an overall minimum tangible net worth level and to maintain a minimum level of liquid assets. As of September 30, 2014, the Company was in compliance with these covenants. As of September 30, 2014, the Company’s primary bank has issued, against the line of credit, one standby letter of credit totaling $113,000. Other than issuing standby letters of credit, the Company has never drawn against the line of credit, nor have amounts ever been drawn against the standby letters of credit issued by the bank.
