Geographical Information

Following the sale of the Photovoltaics Business on December 10, 2014, the Company has one remaining reportable segment: Fiber Optics. See also Note 3 - Discontinued Operations for additional disclosures.

EMCORE's Fiber Optics business provides optical components, subsystems and systems for high-speed telecommunications, Cable Television (CATV), Wireless and Fiber-To-The-Premises (FTTP) networks, as well as products for satellite communications, video transport and specialty photonics technologies for defense and homeland security applications.

On October 22, 2014, EMCORE entered into an Asset Purchase Agreement (the "Digital Products Agreement") with NeoPhotonics Corporation, a Delaware corporation ("NeoPhotonics") pursuant to which the Company agreed to sell certain assets, and transferred certain liabilities of the Company's telecommunications business (collectively, the "Digital Products Business" and, the sale of the Digital Products Business and the "Digital Products Assets Sale") to NeoPhotonics for an aggregate purchase price of $17.5 million, subject to certain purchase price adjustments. On January 2, 2015, EMCORE completed the sale of the Digital Products Business.

The financial results of the Photovoltaics and Digital Products Businesses are presented as "discontinued operations" on the Consolidated Statements of Operations for the three and six months ended March 31, 2015 and 2014; and the assets and liabilities of the Photovoltaics and Digital Products Businesses are presented as "Assets of discontinued operations" and "Liabilities of discontinued operations" on the Consolidated Balance Sheets as of September 30, 2014. No Photovoltaics or Digital Products assets and liabilities remain on the condensed consolidated balance sheet as of March 31, 2015.

We evaluate our reportable segments pursuant to ASC 280, Segment Reporting. The Company's Chief Executive Officer is the chief operating decision maker and he assesses the performance of the operating segments and allocates resources to segments based on their business prospects, competitive factors, net revenue, operating results, and other non-GAAP financial ratios. Based on this evaluation, the Company operates as a single reportable segment.

Long-lived Assets: Long-lived assets consist primarily of property, plant, and equipment and also intangible assets. Long-lived assets that were disposed of as the result of the Photovoltaics and Digital Products Asset Sales were included in "Assets of discontinued operations" on the Consolidated Balance Sheet as of September 30, 2014, and accordingly, are not included in the following table.

As of March 31, 2015 and September 30, 2014, approximately 34% and 47%, respectively, of our long-lived assets were located in the United States. The remaining assets are primarily located in China. During the first quarter of fiscal 2015, as a result of the revision in the estimated amount and timing of cash flows for asset retirement obligations in the United States, the Company reduced its asset retirement obligations liability by $2.9 million with an offsetting reduction to property, plant, and equipment of $2.1 million, and recorded a gain from the change in estimate on ARO obligation of $0.8 million.
