Thanks, Kate. And welcome everyone to our first quarter 2015 earnings call. Since going public a year ago, I'm pleased with the progress we have made in building our franchise. We've continued to enhance our global platform by adding seasoned team members in areas of strategic importance and expertise. We have maintained our intense focus on retaining and developing our talent and have continued to establish deep long-term relationships with clients around the globe. Today I'm going to begin with comments on the quarter, then address our outlook for the firm and finally touch on what we’re seeing in the market. Looking at the first quarter when compared to last year's first quarter, we had a slower start to the year. Revenues were down 13% from what was a record first quarter in 2014. As a result, we reported a decrease in earnings per share as well. While we continue to see significant growth in activity levels with clients, and we are confident in our long term trajectory, our first quarter results were impacted by really three factors. First, the last quarter of last year was a tough comp for us, included several notably large fee events that contributed to a 91% increase in revenues over the prior year. These large fee events also contributed to a somewhat unusual pattern of seasonality last year. Our first quarter 2014 revenues comprised 22% of our full year revenues as compared with prior years where our first quarter has historically been in the mid to high teens of our full year revenue. In the first quarter of 2015, we had a more balanced mix of fees consistent with how our business typically performs. Second, we began to see an extended timeline for certain M&A processes during the quarter particularly with regards to credit sensitive deals such as financial sponsor M&A where we have a very strong franchise. We believe higher multiples and active pressure on regulated banks to tighten the availability of credit was one of the major causes leading to these extended processes and I'm going to touch a little more on this trend later in my remarks. But the good news is that it feels like these issues have worked their way through the system and buyers and sellers have adjusted to what are some of the new capital requirements and issues in transactions. Despite longer completion times, the number of our completed M&A transaction actually increased from quarter 1 2014, and M&A comprised a larger percentage of our total revenues which leads me to a third factor and that is a more subdued restructuring environment. Default rates continue to, I think surprise on the downside and went from 3% to 2% last year and restructuring activities comprises a smaller percentage of our revenues. We estimate approximately 20% of our 2014 revenues were restructuring related, and expect this percentage to decrease through 2015 as our M&A activity continues to grow. We are encouraged by the steadily improving M&A market and our strong and growing of bench senior talent which are driving increased overall activity with clients. We typically look at fees greater than a $1 million as a proxy for transaction closings and had 28 clients paying fees equal to or greater than $1 million in this year's first quarter as compared to 24 clients in the prior period. We are also pleased with the power of our differentiated globally integrated model. The best signal to mean at this, that our model is working is how it resonates with clients around the globe. Just to give you a feel, we are currently advising Hutchison Whampoa, a Hong Kong client on its £10 billion acquisition of O2 in the U.K., the largest transaction announced in Europe in the first quarter. In Australia, we are advising a consortium of investments on the 8.2 billion Aussie acquisition of GE Capital in Australia and New Zealand consumer finance. And that was a second largest transaction announced in Australia in the first quarter. We recently advised Dubai Ports on a $3.5 billion acquisition in Dubai, one of the largest ever public company transaction in Middle East which we wrapped up in the first quarter. In China, we worked on the second largest IPO in Asia-Pacific last year, the 3.7 billion IPO of Dalian Wanda Commercial Properties. And recently our newly opened office in Brazil advised Petrobras on a $127 billion assignment to provide capital markets and debt markets strategies related to liability management, as well as - that wrapped up in the first quarter and as well we had significant transactions for clients in India, Japan and Africa. In only eight years, I think we have built one of the most successful broad and diversed global platforms. So, we feel good about current activity levels and expect to generate continue revenue growth in 2015. Given the longer lead time we have experienced in recent M&A processes, we expect to see this growth manifest itself in the second half of the year and that will be driven by two key areas; First, M&A activity. M&A activity continues to steadily improve and we all participating. All of the fundamentals for a long term steadily improving cycle remain in place. And second, we are growing and developing our team. We continue to invest in our talent and to enhance our global franchise. Today, we have 99 Managing Directors which is up from 87 Managing Directors at the time of our IPO. And we have recently hired another four who will join this summer and strengthen our capabilities in sectors that we expect to be active. For the full year we believe we could have a similar number of Managing Directors as we did last year. Just to remind you, we think of hiring in two ways. One, just opportunistically. When we see a creative talent become available, we are prepared to move quickly. And two, strategically. Over the past few years we invested in our team in Europe where we now have almost 70 bankers, including 19 Managing Directors. We also recently hired two Managing Directors in Europe who will join us this summer and will cover chemicals and oil and gas. We believe we are well positioned to capture market share as European activity improves and it is improving. The dollar volume and number of announced transactions over 100 million was up 9% and 8% respectively over the first quarter in 2014. And our team generated continued revenue growth this quarter. We also continue to be focus on enhancing our coverage of the energy sector where we expect restructuring M&A and other strategic activity to pick up towards the end of the year. Additionally, we are exploring incremental distribution talent for our private funds advisory business and we will probably look to add senior M&A expertise in the U.S. So in summary, we’re confident about our growth prospects for the year. We expect to achieve revenue growth in 2015 and we believe this growth will manifest itself in the second half of the year. While some of the trends that contributed to a slower first quarter have continued into the second quarter, it does feel like the market is beginning to adjust and buyers and sellers are getting back in sync. With that, let me turn the call over to Joe, to discuss the financial results in more detail.
