Good morning, everyone. As many of you know, Gladstone [indiscernible] is the lending fund of The Gladstone Companies. We provide cash flow-based loans to privately held U.S.-based businesses in the lower middle market, which we define as having $20 million to $100 million in revenues and $3 million to $15 million in earnings before interest and taxes and depreciation. Our loans are used to fund private equity buyouts or to make acquisitions or to recapitalize or refinance a company's existing capital structure.
Gladstone Capital was one of the first BDCs focused on lending to the low to middle market and today that dedication, experience and consistency are a core part of our value proposition. We approach the market with an investor perspective and strive to deliver market-oriented capital solutions to support each business's unique capital and growth profile.
The majority of our loans today are to businesses backed by private equity sponsors or owner-operators with significant equity and include a combination of secured first- and second-lien loans and many include equity co-investments. We target to make investments of $8 million at the $20 million, but will opportunistically consider smaller positions in broadly syndicated loans from time to time.
With that introduction, I want to take this time to update our shareholders and analysts on our operating results, our portfolio performance and commentary on the marketplace.
With respect to our investment activity. After pacing well ahead of plan for the first half of our fiscal year through March 31 with originations of over $90 million, we did not make any new investments on the quarter ended June 30, 2015, as several of the proprietary deals we had anticipated closing were delayed and closed after the end of the quarter. In anticipation of funding these new investments, we sold $9 million of our syndicated loan portfolio, and as a result, our net earning assets on the quarter declined by $14 million. Since the end of the quarter, we have closed 2 new proprietary investments totaling $20.2 million. We invested $7.2 million in a secured second-lien debt and equity co-investment in the buyout of Mikawaya by a private equity sponsor. Mikawaya is a producer of Japanese pastries and specialty frozen desserts, which has been family-owned and operated for over 100 years. The company is a dominant player in their niche and is poised to expand beyond their traditional customer base.
Additionally, we closed a $13 million secured first-lien term loan to StrataTech Education, which is a leading operator of a posteducation -- postsecondary skill trade schools. The company has a strong record of student outcomes and placements, regulatory compliance and is backed by 2 experienced private equity sponsors.
In addition to these recently closed deals, we have a healthy pipeline of pending opportunities, which we anticipate to provide strong investment momentum as we go through our fourth quarter.
With respect to the portfolio overview and performance. Over the past several quarters, the cumulative effect of our focus on secured first lien and unitranche investment is continuing to impact our portfolio mix and results. We are currently at a 60-40 mix of secured first lien to secured second-lien debt it in our -- based on the fair value of our loan portfolio. We do not have any unsecured subordinated debt exposures at this time. The combination of the higher-yields available in the lower middle market and our recent focus on modestly leveraged senior secured assets is expected to produce a more attractive and predictable return to support our shareholder distributions regardless of where we are in the credit cycle.
On the whole, the fair value of the existing portfolio decreased slightly by $1.1 million on the quarter as unrealized depreciation of $17.6 million exceeded unrealized appreciation of $16.5 million. The largest driver of the appreciation on the quarter was the continued appreciation of our equity investment in Funko, a toy company that markets licensed pop culture collectibles, which is continuing to report very strong operating performance.
The largest drivers of the unrealized depreciation in the quarter included $5.9 million depreciation of RBC Acquisition, also known as Reliable Biopharmaceutical, and a $2 million depreciation of our investment in B+T Group, a telecommunications tower engineering services business. Both of these latter [ph] companies experienced soft financial results during the first half of 2015, which are expected to improve over the balance of the year.
During the quarter, we also exited Sunburst Media, an underperforming radio operator during the quarter, realizing cash proceeds of $4.7 million and a realized loss of $1.3 million, which was $1 million -- the recovery was $1 million higher than the valuation of last quarter. We believe that over the last few quarters, we have demonstrated successful dispositions of a number of our legacy assets and hope to have one or two more exits to report next quarter.
With respect to our oil and gas exposure. There were no material changes in the quarter. Our industry exposure represents $53.1 million or 15.4% of our portfolio at fair value and continues to perform well given its limited exposure to commodity prices, drilling activity and conservative leverage with weighted average leverage of 2.8x EBITDA and average fixed charge coverage of 2.4x. All companies are covenant-compliant with ample liquidity and are backed by strong and experienced private equity sponsors. Cumulative net unrealized depreciation associated with our oil and gas loan portfolio totaled $1 million as of June 30 and the fair value represents 98.1% of costs.
On the whole, the cumulative net unrealized depreciation investments increased slightly to $53.8 million for the quarter ended June 30 and it represents the bulk of the increase -- decrease in NAV from $9.55 a share to $9.49 a share for the quarter.
Despite some successes on the quarter, our nonaccrual investments and underperforming assets are still higher than we consider acceptable. This quarter, we added Saunders and Associates as a nonaccrual investment as adverse end market conditions for its electronic products and unfavorable exchange rates have compressed the company's revenue. The fair value of Saunders and Associates investment was reduced by $1 million to $1.2 million during the quarter.
As of June 30, 2015, our combined nonaccrual debt cost basis is $49.2 million or 13% of the cost base of all debt investments in the portfolio and has a combined fair value of $10.7 million or 3.5% of the fair value of all debt investments. We are currently working to exit these underperforming assets and we are looking forward to being able to update you in the near future.
With respect to portfolio yields, moving over to our portfolio income profile. The weighted average yield on our interest-bearing debt investments, excluding reserves in our portfolio, was 11.2% as of June 30, which is relatively the same as the 11.1% as of March. For the quarter, total investment income was up 7.7% or $700,000 compared to the prior quarter. Our debt portfolio is well positioned for an interest rate increase with 84% of the portfolio in floating rate investments and 16% in fixed rate investments.
Our floating rate investments typically have a LIBOR floor and the weighted average floor on our variable loans today is 1.9% while the average weighted margin is 9.2% as of June 30. Our proprietary loans, which total 83% of the portfolio at cost, had a weighted average yield of 10.9%, while our syndicates, which total 17% of the portfolio at cost, had a weighted average yield of 11%. The net effect of 100 basis point increase in 1-month LIBOR and the applicable floors would reduce our portfolio net interest income by $775,000 or approximately $0.04 a share.
The other income in our portfolio has been significant at times over the last several quarters, which is primarily due to what we call success fees, and to a less extent -- lesser extent, dividend income. For the quarter ended June 30, 2015, we recognized $510,000 in dividend income and $318,000 in success fee income. In total, other income was up quarter-over-quarter by $345,000.
Success fees are typically due on the change of control and are highly contingent in nature, therefore, we accrue our success fee receivables off balance sheet. As of June 30, the off-balance sheet success fee receivable totaled $9.1 million or about $0.43 per common share.
In addition to what we believe to be a favorable risk profile of a recently originated senior secured first-lien unitranche investment, the asset shift in the portfolio was also made in conjunction with the amendment, extension and expansion of our credit facility. The revised facility, which closed in the June 30 quarter, reduced our borrowing cost and increased the advanced rates against our secured first-lien assets.
With respect to the investment climate and backlog of opportunities and outlook. Inclusive of the 2 deals we closed after the end of the quarter, we've averaged just over $30 million of proprietary originations per quarter, which is consistent with the current level of market activity we are seeing across the lower middle market and our current pipeline of proprietary deal opportunities. We continue to see a proliferation of smaller, newly formed PE funds looking to take on smaller investment opportunities with an increased emphasis on buildup and acquisition investment strategies. These trends are well suited to our low and middle market focus, value proposition and focus on delivering senior secured unitranche financing solutions.
From a liquidity perspective going into the balance of 2015, the competitive dynamics for the middle market loans appears positive including several factors: the cumulative effect of the regulatory pressures on leveraged lending by the commercial banks; the limited funds flow into the broader loan markets, which reduces loan asset demands and potential pressure on middle market spreads; and weak BDC stock prices generally trading below net asset value per share, which serves to lessen the competitive pressure to book middle market loans.
Competition continues to be most pronounced in the large and middle market companies with more than $10 million of EBITDA where the commercial banks and the broadest array of nonbank lenders operate. In the face of this competitive profile, our strategy is to continue to leverage our long-standing reputation in the low end of the middle market and investor-oriented financing approach continues to gain traction. We're focused on investing in our coverage of and relationships with private equity-sponsored community and expect to be able to continue to source attractively priced financing solutions in this market.
We're -- our continuing priorities for the balance of fiscal year -- our fiscal year ending September 30, 2015, will be managing our remaining legacy credits in the portfolio to orderly liquidation, utilizing the enhanced availability under a recently amended line of credit and sales of our syndicated loan position or select first-lien positions to support future growth of our proprietary deal portfolio.
And now, our Chief Financial Officer, Melissa Morrison, will provide an update on the fund's third fiscal quarter's financial results. Melissa?
