Thank you, Greg, and good morning. For the quarter, we reported fully diluted earnings per share of $0.99 and non-GAAP operating earnings per share of $1.01. Both the diluted EPS and non-GAAP operating EPS for the quarter were a record for Selective and resulted in a very strong 14.3% annualized non-GAAP operating ROE. Our results were driven by after-tax underwriting income of $30 million, which generated 7.2 points of ROE and after-tax net investment income of $38 million, which generated 9 points of ROE. We also benefited from lower corporate expenses. As a result of our very strong second quarter results, our year-to-date annualized non-GAAP operating ROE has improved to 10.2%, which positions us well to move towards our target return for the year 2018.
For the quarter, we saw a good growth with consolidated net premiums written increasing 7%, driven by 8% growth in our Standard Commercial Lines segment, 7% growth in Personal Lines and partially offset by a 1% premium decline for the E&S segment.
The growth in Standard Lines was driven by excellent pure renewal price increases, high retention rates and good new business opportunities, including those within our 3 new Standard Commercial Lines states, which are providing us additional runway for growth.
The consolidated combined ratio was a solid 93.7% in the second quarter. On an underlying basis or prior to catastrophe losses and prior year casualty reserve development, our combined ratio was 91.3% compared to 92% of the comparative quarter in 2017, with the improvement largely driven by a reduction to the expense ratio.
For the first 6 months of the year, the consolidated combined ratio was 96.4% and the underlying combined ratio was 93.7%.
Results in the first half were adversely impacted by the first quarter non-CAT property losses, which we discussed last quarter. Our ex-CAT combined ratio she was 90.6% for the second quarter and is 92.7% for the year-to-date.
As Greg mentioned, our ex-CAT combined ratio forecast for the full year 2018 remains at 92% and we're still forecasting 3.5 points of CAT losses for 2018. Although, as always, there's considerable variability in these forecasts.
For the quarter, catastrophe losses were 3.1 percentage points on the combined ratio, down 2.1 points from the comparable period, while the 3.7 points impact for the first six months was in line with the year-ago period.
Non-catastrophe property losses in the second quarter equated to 13.7 points on the combined ratio, which was slightly above our expectation for the second quarter. Year-to-date, our non-catastrophe property losses have impacted the combined ratio by 15.8 percentage points, which is 3 percentage points higher than the comparative period in 2017, with the negative variance principally driven by the heavy non-GAAP profit losses we experienced in the first quarter.
During the second quarter, we experienced $4 million of net favorable prior year casualty reserve development, which lowered the quarter's combined ratio by 0.7 percentage points.
Better than expected claims [ emergence ] in our Worker's Compensation line totaling $17 million was partially offset by $7 million of adverse development in our Commercial [indiscernible] line of business and $6 million of adverse prior year casualty reserve development for our E&S segment.
We also had some pressure on the current accident year and raised our loss specs modestly for commercial auto as well as for our E&S casualty business. Our GAAP expense ratio was 32.9% for the second quarter, which is down 1.3 percentage points compared with 34.2% in the comparative quarter a year ago, mainly due to ongoing expense reduction we have highlighted in the past, coupled with a modest decline in profit-based incentives included in Employee Incentive Compensation.
For the first half of the year, the GAAP expense ratio was 33.3%, which is down 1.1 points from the comparative period in 2017.
We remain focused on seeking out areas of efficiency in cost savings while continuing to invest in our employees and key initiatives around geographic expansion, enhancing our underwriting tools, technology and the overall customer experience.
Corporate expenses, which are principally comprised of holding company costs and long-term stock compensation were down $5.2 million on a pretax basis relative to the comparative quarter.
The primary reason for the reduction in the quarter was a lower amount of stock compensation expense resulting from a decline in the share price during the quarter.
While we expect there to be volatility in this line item based on fluctuations in the share price, we made structural changes to our long-term share-based compensation program in early 2017 that should lead to lower costs over time.
Year-to-date, corporate expenses are down about $6 million.
Turning to investments. For the quarter, after-tax net investment income totaled $37.6 million and was up 24% from a year ago. The year-over-year increase primarily reflects the lower tax rate on investments following the implementation of tax reform as well as the higher book yield for our core fixed income securities portfolio. We continue to actively manage the investment portfolio, tactically seeking opportunities to increase the after tax book yield, while maintaining high credit quality and managing duration risk.
Our average credit rating remains AA- and the effective duration of our fixed-income and short-term investments portfolio is relatively unchanged at 3.9 years.
As we highlighted last quarter, we have made some allocation shifts in the portfolio this year, whereby we -- which we sold a number of tax-advantaged securities and reinvested in corporates and structured bonds, due to the relative value on an after tax basis and post tax reform.
In addition, approximately 17% of the fixed-income portfolio is invested in floating-rate securities, which primarily reset based on 90-day LIBOR. As a result, we continue to benefit from the relatively rapid rise in 90-day LIBOR, which was up 64 basis points this year through June 30.
Many of these floating-rate securities reset in April, which helped drive a 12-basis point increase in our pretax book yields during the quarter for our core fixed income securities portfolio and brought our year-to-date pretax book yield increase to 29 basis points.
Overall, the after-tax yield on the fixed-income portfolio was 2.79% during the quarter compared with 2.2% a year ago. The new money pretax yield on the fix fixed income portfolio during the second quarter was 3.76% and 3% after-tax.
Risk assets, which principally include high yield securities and our public equities and our alternate portfolio, accounted for 7.6% of total invested assets as of the end of the second quarter, and is down slightly from the first quarter as we made a modest reduction to our high yield allocation.
We have been gradually diversifying our portfolio of risk assets and will likely modestly increase our allocation over time, depending on market conditions and opportunities.
Alternative investments, which primarily represent limited partnerships and private equity investments that are reported on a 1-quarter lag, generated a pretax gain of $2 million for the quarter.
Turning to capital. Our balance sheet remains strong with $1.7 billion of GAAP equity and we are adequately capitalized to support our expected growth. We continue to adopt a conservative stance with respect to managing our underwriting risk appetite, investment portfolio, reserving processes, reinsurance buying and catastrophe risk management.
Our debt-to-capital ratio of 20.6% at the end of the second quarter is trending below our longer term target of approximately 25%, and allows us to opportunistically increase financial leverage if we choose to.
With our 1.4x premium to surplus ratio, it means that each point of underwriting margin points to approximately 110 basis points of ROE. In addition, with our 3.34x investment leverage, every 100 basis points of pretax book yield from our investment portfolio results in 275 basis points of ROE.
This unique differentiated business model, combined with our ability to generate pure renewal rate increases positions us very well for the future.
During the quarter, we renewed our property excess of loss and casualty excess of loss reinsurance agreements.
These reinsurance agreements cap our net losses on large individual property and casualty losses at $2 million.
This is a part of our underwriting strategy to reduce the volatility of our underwriting results from large losses in our overall book of business.
With that, I'll turn the call over to John to discuss our insurance operation.
