Thank you, and good morning to everyone. Welcome to our second quarter conference call. Joining me here today is our CFO, Christa Davies. To begin, our second quarter results reflect continued progress with solid growth in our Retail Brokerage business, delivery of synergy savings related to Aon Hewitt and the repurchase of more than 300 million of common stock. Consistent with our messages on previous calls, irrespective of the stock market, economic conditions or other challenges outside our control, we continue to execute on our strategy to substantially strengthen and unite Aon around the globe. Also consistent with previous quarters, I'd like to cover 3 areas before turning the call over to Christa for further financial review: First is our performance against key metrics we communicate to shareholders; second is continued areas of investment across Aon; and third is overall organic growth performance. On the first topic, our performance versus key metrics. Each quarter, we measure our performance against the 3 metrics we focus on achieving over the course of the year, grow organically, expand margins and increase earnings per share. In the second quarter, organic growth was plus 1%, highlighted by solid growth in our Retail Brokerage business, placing us firmly on track for growth in 2011. Adjusted operating margin decreased 220 basis points, driven by the inclusion of Hewitt results, including a significant increase in intangible amortization expense. EPS increased 2% to $0.83, driven by strong underlying performance and effective capital management. Overall, our team views the underlying second quarter results as a quarter of continued progress as we strengthen the firm for long-term growth and value creation. On the second topic, further areas of investments. We believe Aon is in a unique position. Solid operating performance combined with expense discipline and strong cash flow continues to enable substantial investment in colleagues and capabilities. A few examples include, in Risk Solutions, we're invested in innovative technology, such as our Global Risk Insight Platform, which delivers unmatched data and analytics, new revenue opportunities and greater insights into our commission yields across $54 billion of premium flow globally. We're also investing in additional capability and talent, as well as strengthening our international footprint through recently completed acquisitions such as Glenrand in South Africa, which solidifies our position as the largest broker on the continent of Africa. We're investing in client leadership to drive greater productivity and efficiency with the rollout of the revenue engine in EMEA and Asia Pacific, the rollout of Client Promise, which is driving greater retention rates and ensuring clients understand our value proposition and the rollout of our Aon Broking platform to better match client needs with insurer appetite for risk in any geography around the globe. In HR Solutions, we continue to strengthen our industry-leading position in both public and corporate healthcare exchanges, enabling clients to prepare for ultimate changes in healthcare legislation with design, purchasing and administration capability. We're expanding our capability in investment management consulting as highlighted by the acquisition of EnnisKnupp, complementing our incredibly strong U.K. business with over $4.3 trillion in combined assets under advisement. And we're expanding our international footprint as the workplace is increasingly becoming more global with investments in key talent and capabilities across Asia. Finally, we're continuing to invest in expanding our core HR BPO offerings through point solution opportunity such as dependent eligibility audits and assets management. In summary, across Risk Solutions and HR Solutions, our fundamental client-serving capability continues to substantially strengthen around the globe. These investments, fully funded in the context of long-term margin improvement, position Aon very well to take advantage of an improving global economy and a long-term growth opportunity we see across our markets. Finally, on the third topic of growth, I want to spend the next few minutes discussing the quarter for both our segments. In Risk Solutions, overall organic revenue was plus 2%, a continuation of the positive trends we saw in the prior quarter despite soft pricing, excess capital and fragile economic conditions globally. Against these headwinds, which are primarily market-related, we're driving a set of initiatives that continue to strengthen our underlying performance and give us confidence that our Risk Solutions business is firmly positioned for long-term growth and leveraged to an improving economy. With management of our renewable book portfolio through Client Promise and retention rates of 90% or better on average, highlighting strong client satisfaction. New business generation, more than $240 million across our Retail business with strong growth in many markets including China, Africa, Australia, New Zealand, Italy, Denmark and U.S. Retail just to a name a few, highlighting the strength of our global client-serving capability, and investments in new products and service capabilities with the rollout of GRIP, Client Promise and Impact on Demand and global growth in treaty reinsurance, driven primarily by net new business. Turning to the individual businesses. In the Americas, organic revenue growth was plus 3%. Pricing continues to be soft, down low-single digits on average with relatively stable exposure units. But in spite of this headwind, we saw strong growth in both Latin America and in our Affinity products, partially offset by a modest decline in U.S. Retail and continued sector weakness in areas such as construction. However, for construction, despite continued weakness in this important sector, our team delivered a strong quarter of improved performance led by strength in the commercial surety business. We've got a great platform and a great team we plan to keep investing behind to position this business for substantial long-term growth. On the international front, organic revenue growth is plus 3%. Pricing continues to be flat to modestly down on average with firmer pricing in cat-exposed regions. We saw strong growth in New Zealand and across Asia, including double-digit growth in areas such as Thailand, China and Japan, driven primarily by new business activity. We have modest growth in U.K. Retail and EMEA as exposures are generally stable, but economic conditions remain fragile across the region. In Reinsurance, organic revenue declined 2%. However, in the core book of Reinsurance, global treaty revenue drove a 2% increase in total organic revenue. The first quarter of growth in treaty Reinsurance since Q2 of 2009, driven primarily by improved trends in new business and less impact on the pricing side. Capital advisory and facultative placements, which are very much more transaction-driven, drove a 4% decline in total organic revenue as the prior year quarter included significant activity related to cap on [ph] placements. As we reflect on the merger with Benfield, the transaction continues to perform better than our original expectations as the first 2 years were not as much about growth but about strengthening an unparalleled reinsurance platform with unmatched data and analytics, while delivering on the economics of the transaction, including $122 million in synergy savings that remain well ahead of the original schedule. We remain confident and excited about our capability in Aon Benfield. From a pricing perspective, despite significant industry loss experience in the first half, we believe excess capacity globally will continue to drive soft pricing, albeit at a moderately lesser rate of decline with firmer pricing in certain cat-exposed regions. Given these industry conditions for treaty business and the transactional orientation nature of the capital advisory and facultative placements, we would expect the trends in Reinsurance in the second half to modestly improve from the results in the second quarter. Turning to HR Solutions. Overall organic revenue was flat, a modest improvement from the prior quarter as fragile economic conditions placed pressure on corporate discretionary budgets and global unemployment trends. Against these headwinds, which are primarily market-related, we are, again, driving a set of initiatives that continue to strengthen our underlying performance and give us confidence that our HR Solutions business is firmly positioned for long-term growth and leverage through an improving economy, with a high degree of recurring revenue across HR Solutions with strong renewal rates, highlighting strong client satisfaction; solid new business generation with over 150 wins, including more than 20 new mid-market benefits administration wins and a very significant recent win in a leading large financial institution in HR BPO; and continued investments in international and emerging markets and in products and services, such as investment management consulting and healthcare exchanges. Turning to the individual businesses. In Consulting Services, organic revenue was flat, and the results reflect the modest decline from the prior quarter as fragile economic trends globally placed pressure on unemployment and discretionary spend. Solid growth in global compensation and investment management consulting was offset by impact of weak economic conditions in U.S. retirement and health and benefits consulting. And we'd expect modest organic growth in the second half similar to the first half. In Outsourcing, organic revenue was flat and results reflect the modest improvement from the prior quarter. We saw a growth from new client wins in both Benefits Administration and HR BPO, as well as growth from point solutions in areas such as dependent eligibility verification. And we would expect flat to modest organic growth in the second half, a continued improvement from the first half. In summary of our second quarter results, we're delivering solid underlying progress against the key metrics we communicate to shareholders. Events occurring in Japan, Australia, New Zealand; our pending Health Care Reform in the U.S., just to name a few major developments, only reinforce the needs of our clients and the significant long-term growth opportunities for Aon as the industry leader in both Risk and HR Solutions. I'm now pleased to turn the call over to Christa for further financial review.
