Restructuring Charges	3. Restructuring Charges On June 13, 2013 the Company announced a global strategic restructuring plan designed to accelerate the Company’s future growth by focusing resources on the highest potential growth areas and reduce costs by approximately $3.0 million annually. As part of this plan, the Company is: reducing investment in certain non-core professional audio communications product lines; aggressively transferring specific product lines from Singapore to the Company’s lower-cost manufacturing facility in Batam, Indonesia; reducing global administrative and support workforce; transferring the medical coil operations from the Company's Maine facility to Minnesota to better leverage existing manufacturing capacity, and seeking a buyer for its remaining security, microphone and receiver operations; adding experienced professionals in value hearing health; and focusing more resources in medical biotelemetry. During the second quarter of 2013, the Company incurred charges of $199, primarily related to employee termination benefits, from the restructuring of its continuing operations. In the future, the Company expects to incur approximately $100 to $200 in additional cash charges related to employee termination and moving costs.
