Thanks, Aviv. I'm going to spend a few minutes discussing how we fared in the quarter ended March 31, how the portfolio is positioned for the upcoming quarters, our capital structure and liquidity, the financials, then open up for Q&A.
We are pleased with our performance this past quarter. We achieved another substantial increase in NAV during the quarter. Adjusted NAV increased 2.3% from $12.32 to $12.60, and our portfolio continued to improve.
We have several portfolio companies in which our equity co-investments have materially appreciated in value as they are benefiting from the economic recovery. This is solidifying and bolstering our NAV. Over time, rotation of that equity into debt instruments should help grow PFLT's income. We will highlight those companies in a few minutes.
As part of our business model, alongside the debt investments we make, we selectively choose to co-invest in the equity side-by-side with the financial sponsor. Our returns on these equity co-investments have been excellent over time. Overall for our platform from inception through March 31, our $226 million of equity co-invests have generated an IRR of 28% and a multiple on invested capital of 2.9x.
In a world where investors may want to understand differentiation among middle market lenders, our long-term returns on our equity co-investment program are a clear differentiator. As a result of the completion of the CLO financing at PSSL last quarter, we can efficiently grow the joint venture, which should generate additional income for PFLT.
PSSL's assets grew by $103 million during the quarter ended March 31 and has capacity for an additional approximately $100 million of assets over time. This growth can be a substantial driver of NII. The combination of potential income growth from equity rotation, a larger, more efficiently financed PSSL and a growing, more optimized PFLT balance sheet should help grow the company's net investment income relative to the dividend over time.
Those factors, combined with strong portfolio performance through COVID and our $0.22 spillover as of September 30, have led us to conclude that we will be keeping our dividend steady at this point. We are also pleased that we diversified our financing sources this past quarter with the issuance of $100 million, a 4.25% 5-year senior notes to institutional investors in late March.
Although we never predicted a global pandemic, as you may know, we've been preparing for an eventual recession for some time. Prior to the COVID-19 crisis, we proactively positioned the portfolio as defensively as possible. Since inception, we have had a portfolio that was among the lowest risk in the direct lending industry.
As of March 31, average debt-to-EBITDA on the portfolio was 4.2x. And the average interest coverage ratio, the amount by which cash income exceeds cash interest expense, was 3x. This provides significant cushion to support stable investment income. These statistics are among the most conservative in the direct lending industry.
We have only 2 nonaccruals out of 104 different names in PFLT and PSSL. This represents only 3.1% of the portfolio at cost and 2.3% at market value. We have largely avoided some of the sectors that have been hurt the most by the pandemic such as retail, restaurants, health clubs, apparel and airlines. PFLT also has no exposure to oil and gas. The portfolio is highly diversified with 100 companies and 41 different industries.
Our credit quality since inception over 9 years ago has been excellent. Out of 381 companies in which we have invested since inception, we have experienced only 13 nonaccruals. Since inception, PFLT has invested over $3.9 billion at an average yield of 8.1%. This compares to a loss ratio of only 8 basis points annually.
We're one of the few middle-market direct lenders who was in business prior to the global financial crisis and have a strong underwriting track record during that time. Although PFLT was not in existence back then, PennantPark as an organization was investing at that time.
During that recession, the weighted average EBITDA of our underlying portfolio companies declined by 7.2% at the bottom of the recession. This compares to the average EBITDA decline of the Bloomberg North American High Yield Index of 42%. We're proud of this downside case track record in the prior recession.
Based on tracking EBITDA of our underlying companies through COVID so far, we believe that our EBITDA decline will be substantially less than it was during the global financial crisis.
Many of our portfolio of companies are in industries such as government services, defense, health care, technology software, business services and select consumer companies that are less impacted by COVID and where we have meaningful domain expertise. We believe that we are experiencing an economic recovery with some companies and industries being beneficiaries of the environment.
We are pleased that we have significant equity investments in 3 of these companies, which can substantially move the needle in both NAV, and over time, net investment income. I'd like to highlight those 3 companies. They are Cano, Walker Edison and By Light. Cano Health is a national leader in primary health care who's leading the way in transforming health care to provide high-quality care at a reasonable cost to a large population. Our equity position has a cost and fair market value on March 31 of $431,000 and $9.1 million, respectively. We believe there's a massive market opportunity for Cano to grow in the years ahead with the Medicare Advantage program.
The merger with Jaws Acquisition is currently scheduled to close in June. At that time, we will receive another $800,000 of cash and own 825,274 shares of Cano Health in a limited partnership controlled by a financial sponsor, where the sponsor will earn 20% of the exit proceeds. The shares will be locked up for 6 months. From a valuation perspective due to the lockup, the independent valuation firm valued the position with a 6% illiquidity discount to the traded value on March 31.
Walker Edison is a leading e-commerce platform focused on selling furniture exclusively online through top e-commerce companies. As of March 31, our equity position had a cost of $1.4 million and a fair market value of $12.1 million. Shortly after quarter end, the company executed a refinancing and dividend recap, which resulted in shareholders receiving approximately 2x their cost while maintaining the same ownership percentage in the company. This resulted in PFLT receiving a $2.8 million cash payment on its equity position.
By Light is a leading software, hardware and engineering solutions company focused on national security challenges across modeling and simulation, cyber and global defense networks. Our position has a cost of $2.2 million and a fair market value of $11.8 million as of March 31.
All 3 of these companies are gaining financial momentum in this environment, and our NAV should be solidified and bolstered from these substantial equity investments as their momentum continues. Over time, we would expect to exit these positions and rotate those proceeds into debt instruments to increase income at PFLT.
The outlook for new loans is attractive. We are focused on the core middle market, which we generally define as companies with between $10 million and $50 million of EBITDA. We like the core middle market because it is below the threshold and does not compete with a broadly syndicated loan or high yield markets. As such, we do not compete with markets where leverage is higher, equity cushion lower; covenants are light, wide or nonexistent; information rights are fewer; EBITDA adjustments are higher and less diligent; and the time frame for making an investment decision is compressed.
On the other hand, where we focus, in the core middle market, because we are not competing with a broadly syndicated loan or high yield markets. Generally, our capital is more important to the borrower. As such, leverage is lower; equity cushion higher. We have quarterly maintenance covenants, which are real. We receive monthly financial statements to be on top of the companies. If there are EBITDA adjustments, they are more diligent than achievable. And we typically have 6 to 8 weeks to make thoughtful and careful investment decisions.
According to S&P, loans to companies with less than $50 million of EBITDA have a lower default rate and higher recovery rate than those loans to companies with higher EBITDA. We also believe that middle-market lending is a vintage business. This upcoming vintage of loans is likely to be the most attractive we've seen since the 2009 to 2012 time period, which was the time period after the global financial crisis. This vintage is characterized by leverage levels that are lower; equity cushion higher; yields are higher and the package of protections, including covenants, are tighter. After about 5 years of a late-cycle market for middle-market lending, it is refreshing to have an attractive risk/reward available to us.
Let me now turn the call over to Aviv, our CFO, to take us through the financial results in more detail.
