Thank you for participating in today’s call. Joining me from Inogen is CEO, Ray Huggenberger; President and COO, Scott Wilkinson; and CFO and Co-founder, Ali Bauerlein. Earlier today, Inogen released financial results for the second quarter ended June 30, 2016. This earnings release and Inogen's corporate presentation are currently available in the Investor Relations section of the company’s website. During the call and the subsequent Q&A session, we will be discussing plans and projections for our business, future financial results, and market trends and opportunities, including among others, statements regarding our Inogen One G4 rollout, including pricing studies, commencement of international sales and anticipated patient preference, market opportunities, and increased use of portable oxygen concentrators, our strategic focus and objectives, hiring expectations, seasonality, our estimates of the impact of reductions in Medicare and insurance reimbursement rates, and our ability to offset those reductions, changes to the competitive bidding process, cost reduction expectations, expectations for profitability improvement and 2016 guidance, including revenue, net income, adjusted EBITDA, adjusted net income, net cash flow, effective tax rates, and tax benefits, and adjustments. These statements are forward-looking and are subject to substantial risks and uncertainties that may cause actual events or results to differ materially from currently anticipated events or results. Information on these and additional risks, uncertainties, and other information affecting Inogen's business operating results are contained in Inogen's annual report on Form 10-K for the year ended December 31, 2015 and in Inogen's subsequent reports on Form 10-Q and Form 8-K filed with the Securities and Exchange Commission, including Inogen's quarterly report on Form 10-Q for the period ended June 30, 2016 to be filed with the Securities and Exchange Commission. We advise investors to review these risk factors carefully. The forward-looking statements in this call are based on information available to us as of today’s date August 04, 2016, and we disclaim any obligation to update any forward-looking statements except as required by law. During the call, we will also present certain financial information on a non-GAAP basis. Management believes that non-GAAP financial measures taken in conjunction with U.S. GAAP financial measures provide useful information for both management and investors by excluding certain non-cash and other expenses that are not indicative of Inogen's core operating results. Management uses non-GAAP measures to compare Inogen's performance relative to forecast and strategic plans to benchmark Inogen's performance externally against competitors and for certain compensation decisions. Reconciliations between U.S. GAAP and non-GAAP results are presented in the tables accompanying our earnings release, which can be found in the Investor Relations section of our website. We have not reconciled our non-GAAP guidance for adjusted EBITDA, and adjusted net income to the most directly comparable GAAP measures because the timing and amount of material items that impact these measures are inherently unpredictable or out of our control. Accordingly, we cannot provide a quantitative reconciliation of these non-GAAP measures without unreasonable effort. I will now turn the call over to Ray Huggenberger. Ray?
