Thank you, Robert, and welcome to everyone joining today's call. Assured Guaranty began 2017 with a truly great first quarter. Non-GAAP operating shareholders equity per share of $52.51 and non-GAAP adjusted book value per share of $71.51 again reached new highs. Operating income of $273 million for the quarter was more than double that of first quarter 2016 and the present value of new business production, or PVP, totaled $99 million, the highest quarterly PVP since the fourth quarter of 2010. Included in these impressive first quarter results is the impact of completing AGC's January 10 acquisition of MBIA UK, now called Assured Guaranty (London). Rob will give you details on the income and balance sheet effects of this important acquisition, which reinforces our presence in the European infrastructure market and signals our continued commitment to that market while further diversifying our insurer portfolio. We were the only guarantor remaining engaged in Europe, and that commitment has begun to produce meaningful returns. We are clearly seeing renewed demand for our guaranty in the U.K., which we attribute to greater market understanding of the value we have demonstrated, favorable interest rate conditions for refinancing infrastructure debt and the benefits our guaranty provides for investors, subject to Solvency II capital requirements. In December of 2016 and the first quarter of 2017, we guaranteed three bond issues in the UK student accommodation sector alone, where our guarantee is extremely useful in creating long-term inflation-linked bonds. These bonds match project logs and attracts insurance companies and pension funds looking to match their long-term liabilities. Additionally, on March 31, our UK office issued a guaranty for an oversubscribed GBP 261 million 20-year private finance initiative refinancing for St. James Hospital in Leeds. This was our largest UK transaction since 2008. Including additional transactions in the UK utility sector, international public finance transactions produced $40 million of PVP in the first quarter of this year. This is more international production than in any one quarter than in any full-year since 2008. In the public U.S. municipal bond market, where new issued par volumes sold, was 10% below that of the first quarter 2016, monolines still insured 6% of car issuance, including more than 28% of the new issue par sold by single A issuers. Assured Guaranty increased its share of the total insured par sold to 57%, up from 54% in the first quarter of 2016. We continue to lead the industry by ensuring nearly $3 billion of par volume for more than 180 small, medium and large new issues sold in the quarter. Our par insured on new issue sold in the last quarter was approximately 150% of the par insured by the next most active bond insurer. Importantly, we continued to see increased demand for insured guarantees insurance on large municipal offerings. With the industry-leading $12 billion in claims paying resources, we have unparalleled ability to ensure larger transactions without any single transaction representing material exposure relative to our claim paying resources. During the first quarter, we were selected to ensure more than $100 million of par on each of 5 different public transactions. Now we can't predict the timing of these deals of this size, but I can tell you, we have already exceeded that number in the second quarter. Use of our municipal bond insurance on large deals is one sign of growing institutional appreciation of the benefits we offer. Another is the growth of our secondary market business. As more institutional investors recognize the value of our product over the last year, demand for our secondary market municipal bond insurance has grown significantly. The $711 million of secondary market par we insured in the first quarter this year was nearly double our secondary market volume in the first quarter a year ago. In aggregate, our primary and secondary insured pars sold totaled $3.7 billion for the first quarter. Municipal transaction closed in the period produced a strong $52 million of PVP, following the previous quote for $72 million. These consecutive quarters were our two best for municipal PVP in more than three years. The current component of our new business engine, structured finance, produced $7 million of PVP by closing transactions in the aviation finance sector and in insurance reserve financing. We have mandates in aviation and other asset sectors going forward and continue to see opportunities to provide capital management solutions, driven by regulatory and credit concerns. Another way we increased our reservoir of future earnings is by reassuming previously ceded business. These transactions also generally produced commutation premiums that are immediately recognized as income. We increased both on our premium and income in the first quarter by executing a large reassumption of a diversified insured portfolio. We continue to look for additional opportunities of this type as well as termination, wrapped bond purchases for loss mitigation purposes, attractive acquisition targets and strategic investments and financial firms whose business is compatible with ours. Now to one of our favorite topics, Puerto Rico. There have been important developments since our last call. The best news is that after agreeing to reopen negotiations over the restructuring support agreement for PREPA, we came away with a modified agreement that allows for full implementation is fair to the various parties and shows the Puerto Rico government and the oversight board that the consensually negotiated RSA construct provided the best way forward for PREPA. Under the agreed modifications, our responsibilities are substantially similar to the previous version of the agreement. We will provide a surety to support a new issue of securitized bonds, extend the maturity on the relending bonds we purchased from PREPA in 2016 by five years, commit to purchase $18 million of relending bonds in July of 2017, alongside other creditors and provide $120 million of principal payment deferrals in 2018 through 2023, which will be paid back over 10 years. The coupons on these relendings and deferrals range from 7.5% to 9.5%. All of these amounts will be supported by a securitization structure, with an automatic rate true-up segregated for PREPA's credit risk. As we've said before, we favor a constructive approach to resolving Puerto Rico's difficulties as opposed to having costly and time-consuming litigation that will further exacerbate Puerto Rico's challenges. We believe the oversight board, appointed under federal PROMESA legislation, should facilitate execution of the modified RSA under Title VI of PROMESA. Unfortunately, neither Puerto Rico nor the board has shown a commitment to the law or to reaching either consensual agreements. On Wednesday of this week, the Commonwealth with the prior approval of the oversight board, filed for protection under Title III of PROMESA, which is to say they filed for bankruptcy. We probably filed an adversarial complaint seeking a declaratory judgment that Puerto Rico's certified fiscal plan violates various sections of PROMESA and the contracts takings and due process clauses of the U.S. Constitution. The complaint also asked the court to enjoin the Commonwealth and the oversight board from taking any action based on the illegal fiscal plan. Among other things, the plan fails to meet the PROMESA requirement, that it respect the relative lawful priorities or lawful liens established under the Commonwealth's constitution, laws and agreements. Specifically, the plan violates the Commonwealth's constitutional debt priority provision, which provides that GO bonds have priority over all government expenses. The plan does not distinguish between essential and non-essential public services. Instead, the plan presumes that all non-debt expenses are paid before any payments are made for debt service. The plan, therefore, provides approximately $18 billion in average annual non-debt expenses, and ask the creditors to believe that every last penny is necessary to maintain essential public services. PROMESA provides that our fiscal plan should ensure the funding of essential public services, but it is impossible for the oversight board to meet this standard without first determining what services are essential and what services are not. This approach leaves so little available for debt payment that a consensual resolution will not be possible. Also, the plan as constructed undermines investor's confidence in Puerto Rico's commitment to paying debt and respecting creditors rights, which can only defeat PROMESA's stated goal of restoring fiscal responsibility and returning the Commonwealth to the capital markets. The actions of the oversight board will not accomplish its mission, which we share, of long-term stability and economic growth for Puerto Rico. How could the board approve a plan that fails to respect the rule of law and continues to ignore the creditor's protections provided under PROMESA, the Puerto Rico Constitution and the U.S. Constitution without incurring costly and time-consuming litigation. Before I finish my comments, I must mention another favorite topic, Moody's, who has not agreed to our request that they withdraw the AGC rating, despite our terminating the rating agreement with Moody's in January of 2017. We continue to pursue the matter with Moody's. Meanwhile, just last week, Moody's released a new credit opinion on AGC, based again on subjective, non-quantifiable and elusive standards such as its theoretical opinion about AGC's strategic position within our company. The Moody's rating tells an investor little, if anything, about AGC's ability to meet its insured obligations, its financial strength and its strategic position in the market. The current A3 stable Moody's rating failed to reflect the improvement in AGC's financial strength and insured portfolio since Moody's first incorrectly assigned that rating in January of 2013. The latest credit opinion acknowledges many improvements, but the rating has not improved commensurately. From September 30, 2012 to December 31, 2016, AGC's qualified best rate capital increased by 55%, while its statutory net par insured outstanding decreased by 48%. And its leverage ratio, statutory net debt service to claims paying resources, improved from 37:1 to 19:1, clearly representative of a financially strong financial guarantor. The plain fact is that each of our rated -- of our operating subsidiaries is rated in the AA category and as the key global ratings in the Kroll Bond Rating Agency. Based on S&P's capital model, as of year end 2016, we estimate that our company-wide excess capital to be approximately $2.8 billion at the AAA level. Clearly, with our excess capital increasing, we can continue our share buyback program to produce better shareholder returns, while maintaining the high level of financial strength our policyholders enjoy and expect. Additionally, we expect to repurchase more common shares in 2017 than we did last year, closer to the $500 million plus levels of 2014 and 2015. Since January 1, we've repurchased shares totaling $269 million. And as previously disclosed, our board authorized another $300 million in February for share repurchases. We currently have $280 million of authorization available. As is evident in our earnings release, we are off to a very good start in 2017. We continue to lead the public finance insurance market while maintaining appropriate pricing levels relative to risk. With the Fed indicating that two more interest rate increases are likely, demand for our bond insurance should grow. In Europe, our infrastructure transactions are becoming larger, more frequent and worldwide. We have structured finance opportunities in many other sectors. A number of potential acquisitions of legacy guarantors or their insured portfolios are still available, but we are the most logical purchaser. We continue to look for opportunities in the alternative investment asset management segment, and we see these opportunities. We are pleased by the opportunities and the diversity that they represent. I'm looking forward to updating you further this year. I will now turn the call over to Rob.
