Thank you, Robert, and welcome to everyone joining today's call. In 2017, Assured Guaranty demonstrated once again that our long-term vision, well conceived strategy and skilled execution can create impressive growth in the value of our Company. We earned $661 million in non-GAAP operating income increased our non-GAAP adjusted booked value to $9 billion for the first time, further advanced our financial strength and broaden the scope of the Company all while paying substantial claims to protect insured bondholders. Our 2017 accomplishments include, our greatest annual dollar increase in non-GAAP adjusted book value per share, which ended the year in a record $77.74 up 70% from year earlier. A record year-end non-GAAP operating shareholders' equity per share of $56.20, 13% higher than year earlier. The return to shareholders of $571 million of excess capital through $70 million in dividends and repurchases of 12.7 million common shares, a 35% annual growth and the present value of new business production of PVP which reached $289 million to highest annual amount since 2010. A widening of our leadership in the U.S. municipal bond insurance market guaranteed more than 58% of insured bond sold. The completion of our acquisition of the European Arm of MBIA Insurance Corporation, which generated $57 million of after tax gain and increased non-GAAP adjusted book value by $322 million at the acquisition date. Our first direct investment in an asset management firm as part of our strategy to identify alternative investments that complement our existing financial guarantee business provide accretive returns and complement our core strengths, and the continued success of loss mitigation efforts, one of our key strategies including a major RMBS settlement in the fourth quarter for a pre-tax gain of $105 million. In new business production, we saw a significant contributions from all three of our financial guaranteed markets, U.S. Public Finance, International Infrastructure Finance and U.S. and International Structured Finance. And we increased overall PVP for the fourth consecutive year. We accomplished this in the year of continued low interest rates, exceptionally tight credit spreads and disturbing headlines about the plate of the Puerto Rican people and the illegal behavior of the Puerto Rico Government and Oversight Board. In the primary municipal bond market, we continue to lead the industry in terms of both PAR and the number of transactions insured. Issuers continue to increase their use of our insures on larger deals attaching AGM Insurance to 23 new issues with $100 million of more of AGM insured PAR. We also lead the industry in a number of smaller transactions with AGM And Mac guarantying almost 400 bank qualified issues. Importantly for the second consecutive year, PVP generated in the secondary market was in the vicinity of 30% of total U.S. public finance PVP. In 2017 we insured approximately $1.7 billion of secondary market PAR and we count all of our 2017 U.S. public finance business including transactions of both primary and secondary markets Assured Guaranty generated U.S. public finance PVP of $196 million a year-over-year increase of 22%. On the international side, Assured Guaranty's performance was even more noteworthy during 2017. International Infrastructure Transactions generated $66 million of PVP, $14 million more than in the previous two years combined. The transactions we closed show we have returned to being an important player in international infrastructure capital markets, particularly in the United Kingdom. We closed three transactions in the UK senior housing sector where we see ongoing opportunities and ensured a 261 million pound refinancing for St. James Hospital in Leeds one of the largest teaching hospitals in Europe. We also issued a long-term financial guarantee that improves the debt service liquidity for bonds issued to refinance euro tunnel, introducing Europe an application of our guarantee that has a potential enhance long-term debt service liquidity for many other issuers. It is also interesting to note that in 2017 we insured two transactions located outside of the UK which further reflect the recognition, value and acceptance of our guarantee in the European market. Because Internationally Infrastructure Transactions often take a long time to complete, transaction flows tend to be less regular and the timing of closing is not easy to predict. It is therefore encouraging that we have generated PVP in the international market for nine consecutive quarters. While we are still likely to achieve some volatility in the international production, it is clear we have the value proposition and acceptance to succeed in this market. In January 2017 we expanded our international presence by completing our acquisition of MBIA’s European operating subsidiary, which we renamed Assured Guaranty London. The acquisition added approximately $12 million of primarily European infrastructure and utility transactions to our insured portfolio. In time, we believe we can ultimately simplify our international corporate structure and enhance our market visibility by consolidating all of our European insurance subsidiaries under the brand name of AGM’s UK subsidiary Assured Guaranty Europe. Our structured finance business was also productive in 2017 generating $27 million of PVP in a variety of market sectors. It is important to note that this figure excludes a significant amount of PVP that was generated from our municipal structured transaction that was executed by the structured finance group, but accounted for under the U.S. public finance sector. The aviation sector was also a focus where we executed a number of residual value transactions on aviation equipment and we are also focused on the capital management solutions for various institutions such life insurances or financing and risk transfers for regulatory compliance. Additionally, we wrote secondary market policies of some asset securitizations to demonstrate the value of our guarantees in the asset-backed market where we do see additional opportunities in consumer loan, auto loan and home business securitizations. This secondary market program has stimulated interest in our guarantees in the primary asset-backed market. During the year, S&P Global ratings conducted its comprehensive annual review of Assured Guaranty and reaffirmed once again AA stable financial center rating [indiscernible] to our principal operating subsidiaries. Separately, Kroll Bond Rating Agency reaffirmed its AA plus stable rating for MAC, its AA stable ratings for AGC. And in January 2018 a AA plus stable ratings for AGM. As for Moody’s, we have well disputed there is objective methodology and their industry guard for the quantifiable improvement in our financial strength. Given AGC’s AA stable ratings from both S&P and Kroll Bond Rating Agency, we no longer consider a Moody’s rating is center for AGC and ask Moody’s to withdraw its AGC rating. Our continued financial strength, results from our fundamental credit discipline, combined with continued execution of our alternative strategies, but with the 10 years from 2008 to 2017, we have maintain our total claims paying resources at approximately $12 billion. Which is a remarkable achievement considering that during that period, we paid out more than $7.1 billion, comprising $4.4 billion in net claim payments to keep insured investors hold, there were $535 million in dividend to shareholders and $2.2 billion to repurchase 42% of the common shares outstanding at the beginning of our repurchase program in 2013. Acquisition of legacy bond insurers or assuming their insurer portfolio to reinsurance resulted in large and immediate increases to the size of insured portfolio. Which is equivalent to writing new policies in the same PAR of amount. Such acquisitions as to the reserve of unearned premiums that's at a predictable floor for each quarters revenues. Just this month, we announced that we would reinsure substantially all the Syncora Inc’s insured portfolio and commute a significant portion of the exposure we had previously seen at the Syncora Guarantee. This transaction is expected to close by the end of the second quarter. Our Alternative Investments Group is also tests - with identifying and investing in other types of businesses where there is synergy with our core competencies, a risk profile in line with ours and high potential attractive returns. One source of these opportunities is the asset management field, and during 2017, we purchase a limited partnership in a fund, than invest in the equity of private equity managers. We also purchased a minority interest in investment advisory, Wasmer, Schroeder & Company. And highly regarded independent investment advisory firm that is a great strategic fit. Assured Guaranty and Wasmer, Schroeder have complementary strength a municipal credit analysis and both have extensive relationships in the public finance market. We expect to support the continued growth of Wasmer, Schroeder, as it seeks acquisitions of other fixed income asset management firms. Our pursuit of acquisitions in alternative investments is one a way we reduced our excess capital, as our insured portfolio amortizes and our leverage ratios decline. We saw the ratio of our statutory net play outstanding to total claims paying resources decline to 20 to 1 at year end 2017, from 22 to 1, at the beginning of the year. We are also committed to a capital management program, focused on increasing shareholder value. In 2017, we met our stated goal, of repurchasing $500 million of shares annually to increase our value per share. To continue to capital management program, we need to upstream sufficient capital from our operating subsidiaries to our publicly traded holding companies, while keeping a watchful eye on the appropriate capitalization for each of our insurance companies and also adhering to the dividend limitation set by the regulators. In September we [indiscernible] that system on a U.S. subsidiaries through MAC’s repurchase of $250 million of its own shares from its immediate holding company, which is jointly owned by AGM and AGC. The cash on the repurchase was distributed to AGM and AGC in proportions of their ownership, providing those companies with additional liquidity, for streaming dividends or deeming stock. Then in the fourth quarter of 2017, we have paid commission from the Maryland Insurance Administration and the New York Department of Financial Services to redeem $200 million of AGC’s stock and $101 million of AGM’s stock respectfully. These purchases provide funds to the parent company that may ultimately view as share repurchases or alternative investments. Another key strategy is loss mitigation. We have been very successful over the years in obtaining recoveries for breaches of rep and warranties in RMBS transactions. And with the significant settlement, we concluded in the fourth quarter, concerns about our exposure from that sector are substantially behind us. On the public finance side, we are focused on helping Puerto Rico set itself on a path to economic recovery and future assets of the capital markets. After Hurricane Maria, we voluntary withdrew without prejudice and adversary complaint we have filed to challenge legality by the original Puerto Rico Fiscal Player that the Oversight Board and certified. The plan violated numerous provisions of PROMESA and the long constitutions of both Puerto Rico and the United States. We withdrew the complaint to remove with this trash from the recovery efforts. And because of it was clear that the previous certified plan would have to be revised. In a common sense world, which is clearly absent in Puerto Rico, the need to revise the plan should have facilitated new collaboration between the Federal Oversight Board, the Commonwealth, and its creditors. Instead, the revised plan the government submitted, not only squadron the opportunity to correct the flow of the original plan, it actually exacerbated them. After the board demanded further revisions, there is a now a revised-revised plan that’s still offered neither a path to economic revitalization and restoration of capital market access nor a credible basis for debt restructuring. We joined other creditors in a February 14 public letter to the Oversight Board that outlined the current proposals many decisions. I will mention a few today. The plan contributes itself by assuming a massive adverse migration and a 20% decline in population without substantial support and/or any government plans or strategy to stand this decline. It also makes contradictory projections about increases to healthcare cost and government expenses despite this projected following population. It also fails to distinguish between essential and non-essential expenditures, and contains no detailed program for a meaningful reduction in government spending. Incredibly, the plan does allocate hundreds of millions of dollars for litigation expense and outsize the advisor fees while providing no debt service reflecting the government determination to mitigate rather than involve creditors and other stakeholders in developing a comprehensive consensual solution. Certifying such a plan is the service to the citizens of Puerto Rico, who will fail the cost of this litigation and lack of market access for years to come. Additionally, no plan should be certified until all stakeholders know the government's true financial position. Puerto Rico must provide transparent disclosure of its audited 2015 and 2016 financial statements. The data underlined the government’s assumptions in timely and up-to-date information about all financial accounts available to the government. Four and a half months after Hurricane Maria, we stood and noted to have reliable estimates of the cost of restoring normal sit to the Island and the full amount of release A that will be available for the Federal Government much less the long-term economic impact of the disaster. All stakeholders should be focused cooperatively on the immediate recovery needs of Puerto Rico. It’s first step would be for the Oversight Board and the creditors of Puerto Rico Electric Power Authority to agree on a well qualified experience receiver that court could approve the steer PRIFA to its current emergency in a way from the corruption. Political meddling, and general mismanagement that has lead to such scandals as the infamous Whitefish contract, the discovery of a warehouse full of restoration materials and alleged bribe solicited by restoration workers. Talks of privatizing PRIFA without involving its creditors is a non-starter and will only close further disruption to the reconstruction of PRIFA and delay any real improvement in operations due to litigation that result from a no in-creditors’ legal rights. If the Commonwealth, I would say would continue to ignore legal and constitutional rights of creditors and resist working constructively for the conceptual restructuring, costly litigation will continue for the foreseeable future. We expect the creditors will ultimately prevail in either of vulnerable corporate disputes for a number of reasons. One of which is that the Puerto Rico constitution is crystal clear that GO bonds get paid first and that callbacks can only be used to take debt service on Commonwealth debt and PROMESA requires that physical plays must respect constitutional priorities and contractual wins. But if the - intends to retroactively treat creditors unfairly, the news will reverberate across the United States undermining municipal bond investors’ confidence in the terms of their contracts and then politicians will only use to abide by the commitments they make were inherent. Admin kits are repudiating the debt or either oblivious, ill-informed or vastly underestimated for reaching in locations of actually doing so. Such blaming industry guard for the rule of law will make it more expensive for municipalities throughout the United States to fund essential services and infrastructure. This also applies to revenue bonds like the Highway Transportation Authority. The Title III court has turned a blind eye to the legislative history and the contents and purpose of special revenue provisions by clients ordering the transportation agency to turn over revenues for debt service while the Title III case in pending. This ruling is we understand, it will call the question in important investor protection that is fundamental to the revenue bond market. We will be appealing that ruling. The developments in Puerto Rico have demonstrated the value of our guarantees for both people protection, and there is a port of insured bonds and market values. As we continue to defend our rights and convey our message unequivocally with all parties involved in the Puerto Rico negotiations, we know we have the capital liquidity to continue the effort as long as necessary. We also have the confidence in knowing that our financial strength will continue to protect holders of insured guarantee, insured bonds. While Puerto Rico sticks to avoid paying its debt, other United States territories and municipalities have taken a different approach. For example, both Guam and Virgin Islands have said they intend to fully repay their debt obligations and respect the rights of creditors in the rule of law. They serve as a current example of the prudent way municipality or territory can deal with adversity while understanding the importance of maintaining assets under the capital markets in order to the support their recovery as well as their future growth and sustainability. As we have seen with past municipal bankruptcies, working closely with creditors and tabular expertise to help navigate complicated debt restructuring to the optimal path to emerging out of bankruptcy proceeding. Looking towards the year ahead, we remain focused on our central objective, to build long-term value for our policyholders and shareholders. The indications are that the Federal Reserve Rate Setting Committee will continue to raise short-term rates gradually notwithstanding recent stock market volatility. This should eventually push up long-term rates, which is a served momentum to water credit spreads and greater demand for bond issuance. This may take time however to really experience the benefit of increased demand for insurance. Additionally, the new tax regime is likely to have mix effects on the municipal bond market. Potentially including reduced new issue volume and higher yields, because the reduced demand from institutional investors now enjoying lower tax rates. Rob will speak in a moment about the more directed Tax Reform on Assured Guaranty. Our potential wild card is what effect if any proposed federal infrastructure legislation may have on the U.S. public financial business. While we must be prepared for a potential decline in total U.S. public finance issuance of 2018, we believe the market is increasingly recognizing the value of our product. We have the additional advantage of a diversified strategy that includes international infrastructure finance and structured finance. In both of these markets, we are growing recognition of our value preposition along with regulatory incentives to use our products to manage capital more efficiently. Additionally, our alternative investment strategy provides a separate avenue towards growth and positive results, and our capital management program will continue to benefit shareholders. Our business model has proven to be successful for more than three decades, as we build on that success; we continually evaluate the environment and pursuing new opportunities to put capital to work effectively. Assured Guarantee is in a very strong financial position and we have the strategy and resources for a continued success in protecting policyholders and creating value for shareholders. I will now turn the call over to Rob.
