Effective in the fourth quarter of 2013, the Company changed the way it managed the business to focus the business on two operating segments based on homogeneity of products and technology- Grid and IIoT. As a result, the Company, with the assistance of an external service provider, reallocated goodwill of the Company to the Grid and IIoT operating segments using a relative fair value approach. Each operating segment's fair value was determined based on comparative market values and discounted cash flows. As of December 31, 2013, approximately $3.4 million and $5.0 million of the total goodwill balance was attributable to the Grid and IIoT operating segments, respectively.
