Description of Business, Basis of Presentation, and Operating Segment


(a)	Description of Business

Endologix, Inc. (the "Company") is a Delaware corporation with corporate headquarters and production facilities in Irvine, California. The Company develops, manufactures, markets, and sells innovative medical devices for the treatment of aortic disorders. The Company's principal product is a stent graft and delivery system (the "ELG System"), for the treatment of abdominal aortic aneurysms ("AAA") through minimally-invasive endovascular repair ("EVAR"). Sales of the Company's ELG System (including device extensions and accessories) to hospitals and third-party distributors provide the sole source of reported revenue.

The Company's ELG System consists of (i) a self-expanding cobalt chromium alloy stent covered by expanded polytetrafluoroethylene (commonly referred to as "ePTFE") graft material (the "ELG Device") and (ii) an accompanying delivery catheter. Once the ELG Device is fixed in its proper position within the abdominal aorta it provides a conduit for blood flow and relieves pressure within the weakened or “aneurysmal” section of the vessel wall, greatly reducing the potential for the AAA to rupture.

(b) Basis of Presentation

The accompanying Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") and with the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). These financial statements include the financial position, results of operations, and cash flows of the Company, including its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated in consolidation.

The interim financial data as of September 30, 2012, and for the three and nine months ended September 30, 2012, is unaudited and is not necessarily indicative of the results for a full year. In the opinion of the Company's management, the interim data includes normal and recurring adjustments necessary for a fair presentation of the Company's financial results for the three and nine months ended September 30, 2012. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to SEC rules and regulations relating to interim financial statements.

The accompanying Condensed Consolidated Financial Statements should be read in conjunction with the Company's audited Consolidated Financial Statements and Notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2011, filed with the SEC on March 6, 2012.

As part of the financial statement preparation process, the Company's management has evaluated whether significant events have occurred after the balance sheet date of September 30, 2012 through October 31, 2012, representing the date this Quarterly Report on Form 10-Q was filed with the SEC, and concluded that no additional disclosures or adjustments were required.

The Company has one reportable operating segment that is focused exclusively on the development, manufacture, marketing, and sale of ELG Systems for the treatment of aortic disorders. For the nine months ended September 30, 2012, all of the Company's revenue and related expenses were solely attributable to these activities. Substantially all of the Company's long-lived assets are located in the U.S.
