Thank you, Laurie. Before we move on to review of our strategy, I'd like to go over the progress we've made in the last couple of years and to remind everyone why we're excited about the future here at Quest. Over the past two years, we shrank the revenue base by 44% by eliminating business that just didn't make sense and adding business that can sustainably produce attractive margin and returns. With that lower revenue base, we grew gross profit dollars by 17% in the last two years which is driven by improving the revenue mix and improving operational efficiencies. Last year we turned the corner from adjusted EBITDA losses to profitability and over the past two years, adjusted EBITDA showed nearly a $4 million improvement. We've also turned the corner on GAAP profitability. While we still have a way to go to reach adequate profitability returns, we've produced a first net -- quarterly net income in our history during the fourth quarter and we're well-positioned to grow GAAP profitability for years to come. These financial results are just the beginning of what we can do and I expect improvements to continue at a rapid pace. We're now targeting the right business and we have the right back office in place to execute. With this foundation, we're ready to resume growth of both top and bottom line. Over the next three to five years, I'm optimistic, we'll be able to return to revenue at the levels we have achieved in the past, while producing profit margins at our current target level. I now will recap the aspects of the business that give us confidence in achieving those goals. First, of course, there's tremendous efficiencies of scale and scope. We've processed millions of tons of waste during 2018 in every state across the U.S. We're the only company with a national footprint and the service offering that includes almost all waste streams. This provides a significant competitive differentiation. Second, we have a strong brand and a reputation of solving customer problems, by utilizing us customers can focus on their core business. Third, we have an asset-light business model that gives us the ability to scale rapidly, with less need for growth capital. Finally, there are significant and disruptive choices in how companies think about handling their waste, environmentally and socially responsible companies are increasingly looking for economical ways to recycle, instead of sending waste to a landfill. Quest is well-positioned to benefit and in some cases take a leadership role in affecting the secular growth trend. And what's been the balance of my prepared remarks, talking about the initiatives we have to grow the business. To-date, I think, we've done a great job of repositioning the company, improving our operations and reaching profitability. 2019 will be the year that we grow the top line. We plan to grow in three primary ways. The first way is very straightforward. For those existing customers, we will continue to grow by adding locations, as well as selling to them additional services. To capture this opportunity, we've established a clear delineation between farmers and hunters in our organization. With better alignment in our sales organization, our sales reps can build stronger relationships and expand their business with existing customers. The second way we plan to grow is by developing new service offerings that help customers address issues. We have a reputation of being innovative problem solver, creating new services not only help to create loyalty with our existing customers, it provides us opportunities for growth with a differentiated service offering for other current and prospective customers. To illustrate my point, I can highlight a few examples of new services we've recently introduced. We've created a new line of business for wastewater recycling for a large industrial client that reduced the client's costs and converted contaminated water into potable water. We developed an organic solution -- or, excuse me, organic waste program for large retailers in State of California to bring them into compliance with new state regulations. Quest has worked with a large food manufacturer in developing a process to divert expired goods going directly into a landfill. Instead the expired goods are not sent to landfill, they're sent to a depackaging site, giving them a higher percentage of landfill diversion, a key part -- which is a key part of their sustainability goals. Finally, we expect growth to come from a greater emphasis on new customer acquisition. During the latter half of 2018, we added several talented sales executives with 15 to 20 years of experience in relationships in specific verticals. Our team is building a strong pipeline based on relationships and we're getting a better understanding of the sales cycle and how those opportunities move through the pipeline, particularly in new end markets. It will take time for our pipeline to continue to mature, but we have recently received several smaller wins in food manufacturing, automotive and also in the property management market. In summary, we're pursuing multiple opportunities to reignite revenue growth. We have multiple shots on goal and we don't have to have 100% success rate to reach our targeted growth numbers. We've gone through a learning curve as it relates to entering new markets and I believe we're getting better at assessing these factors that lead to success in these markets. Before I open the call to questions, I have a few comments that make about our outlook. Growth from our existing customer base remains strong and our pipeline in new business is growing and maturing. As such, we believe our top line will grow within our targeted annual range of 10% to 15%. As Laurie said, we're managing the business so we continue to deliver gross margins within our targeted range as the low to mid-teens. While we're making some incremental investments in sales and marketing expense, we expect our operating expenses will continue to decrease as a percentage of revenue and demonstrate the operating leverage that exists in our business model. As a result, the bottom line should continue to grow at a faster pace to the top line. We're excited about our prospects, our outlook and business opportunities going forward. We expect the pace at which we add and renew business will accelerate. We believe our stronger foundation will allow for a sustainable business that can consistently grow our revenue, our profitability and ultimately shareholder value. I look forward to keep you updated on this progress. We now like the operator provide instruction on how listeners can queue up for questions. Operator?
