Thank you, Chris, and good morning, everyone. Across our business, we remain focused on the underlying fundamentals, including pricing, underwriting and expense management, while we continue to manage the still emerging impacts of the global pandemic. Multiple catastrophes also provided added challenge to the quarterly results. Nevertheless, progressing levels of economic activity contributed to a much improved top line trajectory during the quarter, and we're pleased with the progress achieved on many of our 2020 initiatives, as I will comment on this morning.
Overall, Property and Casualty core earnings were $428 million for the quarter, and written premium was $3 billion, down 3% from prior year. The underlying combined ratio of 90.6, included $37 million or 1.2 points of COVID losses, was 3 points lower than last year. Excluding COVID losses, each of our businesses reported underlying margin improvement.
Before I get into the segment details, let me summarize the actions we took this quarter with respect to COVID losses, CATs and prior year development. In Commercial Lines, incurred COVID underwriting losses of $37 million were down significantly from the second quarter. Gross workers' compensation COVID losses were $65 million, including a retroactive provision for presumptive coverage in New Jersey and Connecticut. Offsetting the gross loss was continued non-COVID-specific favorable workers' compensation frequency of $48 million, driving a net impact of $17 million. Financial lines and other losses were $20 million, primarily for D&O and E&O.
Turning to catastrophes. We incurred $229 million in the quarter. Industry losses were also elevated due in large part to Pacific Coast wildfires, hurricane Laura, tropical storm Isaias and the Midwest derecho event. We have made significant advances in our CAT modeling and underwriting capabilities. For example, we're confident our incurred wildfire losses in the quarter were lower due to specific underwriting actions taken previously. Over the last 2 years, we have reduced our overall California homeowners policy count approximately 17%, and our footprint in the 5 costliest wildfires this season is down 35% over that same time period.
Net favorable prior year development for the quarter was $75 million. We continued to experience favorable loss emergence in workers' compensation, Small Commercial Spectrum liability and Personal Lines auto liability. U.S. professional liability claim activity is also developing favorably.
Within the Navigators business, we increased prior year reserves $14 million primarily in wholesale construction. The entire increase was reinsured by the adverse development cover.
Turning now to our business line results. The Commercial Lines third quarter underlying combined ratio was 93.7, slightly better than prior year. Favorable property results and a lower expense ratio were partially offset by 1.6 points for COVID losses and a few large marine losses in the international Global Specialty book.
A few comments about the expense ratio. First, reduced travel and incentive compensation are contributors this year. Second, we're starting to see some modest early wins from our Hartford Next transformation program, which will carry into subsequent quarters. And finally, we continue to benefit from actions we took this year to reduce acquisition costs. As I pivot to pricing, we continue to achieve excellent pricing gains. For the quarter, renewal written pricing in Standard Commercial Lines was 3.7%, nearly flat with Q2. Excluding workers' compensation, pricing was a solid 8.2%, slightly ahead of our strong second quarter. Layering in U.S. Global Specialty lines, brings ex workers' comp Commercial Lines pricing to approximately 11% for the quarter, a very strong result.
In Middle Market, renewal written pricing in the U.S., excluding workers' compensation, increased 10.3%, up just over 0.5 point from second quarter and 440 basis points higher than the third quarter of 2019. Property, general liability and auto pricing are holding steady near or slightly above double digits.
In Global Specialty, we're also seeing continued strong pricing gains in both our U.S. wholesale book as well as the international portfolio, which is primarily written in Lloyd's. The U.S. wholesale book achieved 26 points of rate in the third quarter, up 1 point from quarter 2. Auto was in the low teens, while property lines are now in the mid-20s and excess casualty in the mid-30s. Both property and excess casualty are approximately 5 points higher than last quarter. Pricing gains in the international portfolio remained steady with very strong results in professional lines, energy and cargo.
Let me now share a few more details on our commercial businesses. Small Commercial posted an underlying combined ratio of 87.7, 0.7 point better than third quarter 2019 when COVID losses of 0.5 point are excluded. Small Commercial written premium was down 1% versus prior year. Driven by favorable audit premiums, the result was much better than we expected 90 days ago. Top line will continue to be impacted by somewhat lower exposures as a result of COVID impacts on the economy. Small Commercial new business declined 14% versus prior year, yet it's up 9% versus the second quarter.
Spectrum, our industry-leading packaged product, saw a 15% sequential growth and record new business in September. Our new Spectrum product delivers insurance coverage recommendations tailored to individual small businesses, real-time transparent pricing and uses advanced analytics to prefill underwriting information and classify risks for an unparalleled agent quoting experience. I am thrilled with the results and the outstanding feedback received from our agents.
As expected, policy retention in Small Commercial was lower in the quarter, largely driven by the billing hold actions from the second quarter. Premium retention also declined, but to a lesser extent, as the average premium of canceled policies was lower, reflecting the impact of the pandemic on Main Street America and the micro segment of Small Commercial. Combining these past 2 quarters, average policy retention remains strong.
Turning to Middle & Large Commercial. We reported an underlying combined ratio of 97.7 in the third quarter, 3.5 points better than prior year after excluding COVID losses of 1.6 points. A favorable expense ratio, lower non-CAT property and improved national account losses drove the ex COVID margin improvement. Written premium declined 2% in the quarter, largely driven by the impact of lower insured exposure. New business in Middle Market was down 10% versus prior year but up 32% from the second quarter. Submission flow, hit ratio and average premium in our core Middle Market book all improved over second quarter levels. While retention declined, I continue to be pleased with the margin improvement driven by our pricing and underwriting actions.
Moving to Global Specialty. Written premiums declined 2% in the quarter. The domestic U.S. business grew 5% with solid contributions across most lines, while international written premium declined 23%, driven by underwriting actions to improve the profitability of the book. The underlying combined ratio was 98.2 this quarter, 1.6 points better than prior year after excluding COVID losses of 3.6 points. Margin improvement in U.S. wholesale and a lower expense ratio were partially offset by $11 million or 2 points from 4 large losses in the international marine book, including the Beirut and Tilbury port explosions. I do not see these losses as a trend, rather we expect to incur large losses in this book from time to time. We continue to be pleased with margin expansion in Global Specialty. Year-to-date, the underlying combined ratio was 100%, including 5.5 points for COVID losses. Excluding the impact of COVID, we've seen approximately 4 points of improvement from the second half of 2019, almost entirely coming from the Navigators book.
Shifting over to Personal Lines. Written premiums declined 5% in the quarter. The result was partly impacted by the catch-up cancellations from the second quarter's grace period extension, along with the continued declines in the agency book. New business premium declined 10%, driven by lower responses, which outweighed an increase in conversion rates. Responses were up a very strong 9% in the second quarter, so some of this decline was expected. Despite lower growth, we had another strong quarter of underwriting results.
In Personal Lines auto, the underlying combined ratio of 84.9 was 13.9 points better than 2019. Consistent with the industry, frequency continues to run well below prior year. However, due to the demographics of our customer base, our third quarter frequency reduction of plus 20% has been better than industry results. We expect this trend to return to historical levels with the adoption of therapeutics and the introduction of a vaccine targeted for 2021.
In home, the underlying combined ratio of 74% was 2.6 points better than prior year, driven predominantly by favorable non-CAT weather in the quarter.
Before I turn the call over to Beth, let me close by saying that I'm encouraged by our momentum on a number of fronts. After a very challenging second quarter, Commercial Lines written premium and new business momentum picked up in the third quarter, gaining traction with written premium almost back to prior levels. Pricing continues to be strong, and our underwriting actions across Global Specialty and Middle Market books are demonstrating progress. And our view of loss cost trends for accident year 2020 have not materially changed. With continued strong written pricing achieved in nearly all lines, except workers' compensation, we are clearly exceeding loss cost trends across most of our book. We need improved underwriting performance to offset the continued downward pressure on investment income, as Beth will describe. I look forward to updating you on our progress and results after year-end.
Let me now turn the call over to Beth.
