Thank you. Good morning, and thank you for joining Xtant Medical's fourth quarter and full year 2017 earnings call. Yesterday afternoon, Xtant issued a press release announcing fourth quarter and full year 2017 financial results and also filed its Form 10-K for the year ended December 31, 2017. My name is Laura Kendall, and I am serving Xtant Medical as Deputy Restructuring Officer and Principal Accounting Officer. Joining me today for the conference call will be Carl O'Connell, Chief Executive Officer for Xtent. At this time as noted, all participants are in listen-only mode and a brief question-and-answer session will follow the formal presentation. Today's call is being webcast and will be posted on the company's website for playback. We expect the duration of the call to be approximately 30 minutes. If I could for a moment just repeat some of the important cautions regarding forward-looking statements. During the course of this call, management may make certain forward-looking statements regarding future events and the company's expected future performance. These forward-looking statements reflect Xtant's current perspective on existing trends and information and can be identified by such words as expect, plan, will, may, anticipate, believe, should, intends and other words of similar meaning. Any such forward-looking statements are not guarantees of future performance and involve risks and uncertainties, including those noted in the Risk Factors section of our most recent annual report on Form 10-K that was filed yesterday. In addition, any unaudited or pro forma financial information is preliminary and does not purport to project the future financial position or operating results of the company. Actual results may differ materially. For the benefit of those of you who may be listening to the replay, this call was held and recorded on Tuesday, April 3, at approximately 09 A.M. Eastern Time. Since then, the company may have made additional announcements related to the topics discussed herein. Please reference the company's most recent press releases and current filings with the SEC. The company declines any obligation to update these forward-looking statements, except as required by applicable law. For today's call I am going to begin with a brief review of the company's financial performance for the fourth quarter and year ended December 31, 2017. I will also discuss the restructuring transactions that were executed last month and then we'll turn the call over to Carl to discuss Xtant's business performance. In 2017, the company undertook a review of its operations with the objective of improving profitability and liquidity, identifying areas to strengthen sales, improve gross margin, gain operational efficiency, and enable cost containment and better manage our assets. We expect this review and result in improvements to continue into 2018. Consolidated total revenue for the three months ended December 31, 2017 was $19.3 million compared to $24.5 million of revenue for the same period of 2017. For the 12 months ended December 31, 2017, revenue was $82.5 million compared to $89.4 million for the 12 months ended December 31, 2016. The decline in year-over-year sales is primarily result of evaluating the contribution margin from our sales distribution channels and transitioning away from unprofitable distributor relationships to improve profitability going forward. In addition, the highly competitive environment surrounding fixation products and no new hardware product introduction in 2017 adversely affected revenue. Good sales momentum in biologics sales offset these declines and Carl O'Connell will expand on these factors later in the call. Consolidated gross profit for the fourth quarter of 2017 was $10.3 million or 53.2% of revenue compared to gross profit of $17.5 million or 71.6% of revenue for the same period of 2016. For full year 2017, consolidated gross profit was $50.1 million or 60.6% of revenue compared to $62.3 million or 69.2% of revenue in 2016. During the fourth quarter and full-year 2017, additional reserves and impairment charges were taken related to excess inventory and inventory in surgical instruments on a consignment that maybe missing or not returned to the company or related to litigation with the former distributor. These charges totaled $2.5 million in the fourth quarter and $5 million for the full year 2017, lowering gross margin as a percent of sales by 12.7% and 6% in 2017. A shift in sales mix favoring biologics which carry at lower margins and fixation products caused remaining decrease in gross margin. Fourth quarter 2017 operating expenses were $34.6 million compared to $18.7 million in the fourth quarter of 2016. For the year 2017 operating expenses were $87.9 million compared to $69.8 million in 2016. The increase in operating expenses was largely due to a one-time fourth quarter impairment charge of $17.6 million related to intangible assets acquired in the 2015 X-spine acquisition. There was 4.7 million of one-time expenses incurred as a result of the ongoing turnaround and restructuring of the company and $1.9 million of separation related expenses. Operating expenses were also lower due to continuing cost containment and efforts to improve efficiency throughout the company. The company defines EBITDA as earnings before interest taxes depreciation and amortization and other income expense such as gain or loss on sale of assets. Adjusted EBITDA is EBIT less nonrecurring expenses and noncash stock based compensation. Adjusted EBITDA for the fourth quarter of 2017 was a loss of $1.1 million compared to fourth quarter 2016 adjusted EBITDA gain of 727,000. Full year 2017 adjusted EBITDA was a loss of $1.9 million compared to 2016's adjusted EBITDA gain of $1.6 million. The lower adjusted EBITDA is a result of lower sales volume and the impact of inventory reserves taken in the fourth quarter of $1.9 million and for the full year $2.7 million. With respect to our liquidity, as of December 31, 2017 we had $2.9 million of cash and cash equivalents, $12.7 million of net accounts receivable and $22.2 million of inventory. In addition the company had about $2.2 million available under its credit agreement. As previously noted in press releases and SEC filings which can be found in the company's website, Xtant successfully completed the recapitalization of the company lowering its debt and accrued interest by approximately 76 million through a conversion of all convertible debt and related interest to common stock. This transaction has returned stockholders equity to a positive position. In addition the company completed a private placement of common stock for $4.8 million in net proceeds enhancing the company's liquidity position. Xtant has successfully maintained its position on the New York Stock Exchange American and shareholders have selected a new Board of Directors in February composed of both independent directors with significant industry experience and representatives of Orbimed who now own approximately 70% of Xtant's outstanding common stock. The company is planning to conduct a common stock rights offering to its shareholders in 2018 as noted in the various SEC filings and press releases and that will further enhance the company's liquidity position. With that, I'd like to turn the call over to Carl O'Connell to go over some of the business highlights and strategy. Carl?
