Deanna D. Strable
Executive Vice President & Chief Financial Officer at Principal Financial Group
Thanks, Dan. Good morning to everyone on the call.
This morning, I will share the key contributors to financial performance for the quarter, details of our current financial and capital position and an update on our commercial mortgage loan portfolio. Our second quarter results demonstrate the strength and resiliency of our diversified business model. Despite real estate-related market pressures on a number of key metrics, including total company variable investment income, as well as PGI net cash flow and revenue, we're starting to see signs of recovery and positive momentum in real estate in the broader investor market.
Reported net income was $389 million in the second quarter. Excluding income from exited businesses, net income was $325 million with manageable credit losses of $37 million. Credit drift was a positive $5 million in the quarter. On a year-to-date basis, credit drift has been a slight benefit to capital. We still feel good about our full year expectations for credit drift and losses despite the banking sector challenges earlier this year. Excluding significant variances, second quarter non-GAAP operating earnings were $415 million or $1.69 per diluted share.
As detailed on Slide 12, significant variances had a net negative impact on our second quarter non-GAAP operating earnings of $53 million pretax, $39 million after tax and $0.16 per diluted share. The significant variances included lower than expected variable investment income in RIS, Principal International and Benefits and Protection as well as unfavorable impacts in Principal International from inflation and noneconomic LDTI discount rate impacts. Variable investment income was positive in total for the quarter and at a similar level as the first quarter. Prepayment fees and real estate sales were immaterial, causing VII in total to be lower than our run rate expectation.
Macroeconomics were generally favorable in the second quarter as the S&P 500 daily average increased 5% from the first quarter and 2% from the second quarter of 2022. The benefit to our fee based businesses from this positive performance was partially offset by a decline in daily averages for small cap, mid-cap and international equities as well as fixed income. Foreign exchange rates were a modest tailwind on a quarterly basis relative to the first quarter and the second quarter of 2022, but remain a meaningful headwind of $12 million pretax on a trailing 12 month basis. We continue to focus on managing expenses with pressured fee revenue across the enterprise. Through these efforts, compensation and other expenses have decreased at the enterprise level compared to a year ago despite inflationary pressures on salary levels and other expenses.
As a reminder, comparisons to a year ago are impacted by the reinsurance transactions that closed in the second quarter of 2022. Excluding significant variances, revenue growth and margins across the businesses were in line with our second quarter expectations and within our guidance ranges with the exception of PGI revenue growth. Compared to a year ago, PGI performance fees and transaction and borrower fees were down approximately $50 million on a gross basis, pressuring revenue, margin and pretax operating earnings. This decrease was anticipated in our full year guidance ranges. PGI's quarterly margin of 35% was within our 34% to 37% guided range and improved from the seasonally low first quarter.
Specialty Benefits pretax operating earnings, excluding significant variances, increased 29% over the year ago quarter, fueled by growth in the business, including an 8% increase in premium and fees and improved loss ratios driven by strong underwriting and disability and group life. Turning to capital and liquidity, we remain in a strong financial position. We ended the second quarter with $1.2 billion of excess and available capital, including approximately $800 million at the holding company, which is at our targeted level, $340 million in our subsidiaries and $100 million in excess of our targeted 400% risk based capital ratio.
We returned $255 million to shareholders in the second quarter, including $100 million of share repurchases and $155 million of common stock dividends and we retired $700 million of long term debt during the quarter using the proceeds from issuances in the first quarter. As expected, we generated strong free capital flow in the second quarter and remain focused on 75% to 85% free capital flow conversion for the full year. Last night, we announced a $0.65 common stock dividend payable in the third quarter. This is a $0.01 increase and is in line with our targeted 40% dividend payout ratio. We remain focused on maintaining our capital and liquidity targets at both the life company and the holding company, and we'll continue pursuing a balanced and disciplined approach to capital deployment.
As shown on Slide 5, our investment portfolio remains high quality, aligned with our liability profile and well positioned for a variety of economic conditions. Specific to our real estate portfolio, it is high quality and positioned well to withstand potential economic stress. We revalued the portfolio again in the second quarter, reflecting the most recent cash flows and other underlying data. The commercial mortgage loan portfolio remains healthy. The current average loan to value is low at 47% and debt service coverage ratio is strong at 2.5 times. This is relatively unchanged from the first quarter and significantly improved from 2008 levels.
Turning to our office exposure within the CML portfolio, it is geographically diverse and high quality. 100% of the year-to-date 2023 maturities have been paid off and we are confident in the outcome of the remaining four office loans maturing in 2023. Throughout 2023, we are actively revaluing the entire office portfolio each quarter. As of the second quarter, we have cumulatively reduced the portfolio valuation by 25% from the peak. Our current valuation is approximately 23% below the implied index value, highlighting our conservative approach relative to the broader market.
The current loan to value on our office portfolio increased slightly to 57% as we further reduce valuations, while the debt service coverage ratio improved to 2.6 times. We have the experience and a long established track record of navigating real estate cycles. We are confident in the quality of our real estate portfolio and remain diligent in monitoring it and proactive in servicing it. It is high quality, well diversified and a good fit for our liability profile. We continue to be focused on maximizing our growth drivers of retirement, global asset management and benefits and protection, which will continue to deliver long term growth for the enterprise and long term shareholder value.
This concludes our prepared remarks. Operator, please open the call for questions.
