As a reminder, this call is being recorded for replay purposes. I will now turn the call over to David Golub, Chief Executive Officer of Golub Capital BDC.

David B. Golub -- Chief Executive Officer

Thank you, Ingrid. Hello everybody, and thanks for joining us. I'm joined virtually today by Ross Teune, our Chief Financial Officer; and Greg Robbins and Jon Simmons, both Managing Directors at Golub Capital. We and the rest of the Golub Capital team hope that you and your loved ones are all safe in these challenging times. This morning, we issued our earnings press release for the quarter ended June 30 and we posted an earnings presentation on our website. We'll be referring to that presentation throughout today's call.

Let me start with two headlines. The first headline is that GBDC's results for fiscal Q3 were consistent with the estimates we filed on July 15. Adjusted net investment income per share was $0.28, adjusted EPS was $0.94 and NAV per share was $14.05. The second headline is that our fiscal Q3 results were strong. The portfolio generated solid adjusted net investment income and demonstrated strong resilient credit results, including the reversal of a meaningful portion of the unrealized losses that depressed performance in fiscal Q2. I'm going to start by reviewing key performance drivers for fiscal Q3 and then I'm going to go through GBDC's results for the quarter in detail with a lot of help from my colleagues on the phone. After that, we'll take your questions.

On Slide 6, we've outlined three themes beyond good underwriting that we believe drove GBDC's strong fiscal third quarter. First, the US economy began reopening sooner than expected; second, GBDC's portfolio companies generally performed better than expected, especially the ones in impacted sub-sectors; and third, our private equity sponsors have generally stepped up to support their portfolio companies.

Let me elaborate on each of these three. First, the economy reopened faster than we expected. When we did our risk assessments in late March and April, our base case was a meaningful reopening by mid-summer. Our downside case was a bit after Labor Day and our upside case was the end of June. In fact, we saw substantial reopening in May.

Now maybe Dr. Fauchi is right [Phonetic], and this was too soon from the standpoint of controlling COVID. But we believe the earlier reopening gave a substantial boost to many borrowers in GBDC's portfolio. Second theme within GBDC's portfolio in general, borrowers performed better than expected, especially those in COVID-impacted sub-sectors. You'll recall from our fiscal second quarter earnings presentation that we focused on five industry sub-sectors where we saw more risk of COVID impact; restaurants, dental care, eye care, fitness franchises and retail.

In fiscal Q3, we're encouraged to see that many of GBDC's obligors in these industry sub-sectors performed better than expected. In general, most of GBDC's restaurant retail obligors found ways to stay open, to cut costs, to pivot, to emphasize takeout delivery curbside or Internet-based models. Some of the obligors in these industry sub-sectors actually posted same-store sales gains during the quarter. And our dental and eye care obligors who were closed for a period of time, have also in general opened stronger and better than we expected.

Third theme, our private equity sponsors are generally stepping up to support their portfolio companies. We worried in March and April, at the beginning of COVID, that sponsors would have so many problem children that they wouldn't have bandwidth or sufficient capital to be able to address them. So far, those worries are not playing out. We're seeing sponsors contributing time, expertise, operating executives and in many cases capital. We think this reflects the strength of our borrowers, the strength of our sponsors and the strength of Golub Capital's relationships with those sponsors.

GBDC's credit results for fiscal Q3 reflect these three themes.

On the right hand side of Slide 6, we've highlighted four impacts on GBDC, that we will discuss further over the course of today's presentation. Let's start with the first of those impacts, improved internal performance ratings for the GBDC portfolio as a whole.

Please turn to Slide 7. You'll recall we highlighted in last quarter's earnings presentation, the downward migration in our internal performance ratings from categories four and five, those are loans that are performing at or better than expectations at underwriting. So category three, which are loans that are performing or expected to perform below expectations. Category three increased from 7.2% of the portfolio at fair value at December 31 to 26.5% of the portfolio at March 31. The percentage of the portfolio performing materially below expectations in categories one and two was essentially unchanged in the March 31 quarter.

In the quarter ended June 30, consistent with borrowers performing better than our expectations, we saw improved performance ratings, specifically we sold loans in categories four and five increased from 71.5% of the portfolio at fair value at March 31 to 76% of the portfolio at June 30. Category three loans went down from 26.5% of the portfolio at March 31, to 22.3% of the portfolio at June 30. Even better, the percentage of the portfolio in categories one and two, those are loans performing materially below expectations decreased. While the improvement in risk ratings is encouraging, I don't want to gloss over the fact that the proportion of the portfolio rated three is still higher than the range we typically saw pre-COVID. But I want to put that difference in context. given today's unusually uncertain environment, we are quick to downgrade loans to category three. When a loan migrates to category three, it automatically triggers an increased level of scrutiny and oversight.

Our approach is designed to take full advantage of the breadth and depth of resources of the Golub Capital platform. Category three doesn't mean defaults or losses are necessarily going to occur, in case in point being the material subset of GBDC's loans rated three in the March 31 quarter, that migrated this quarter up to categories four and five. We've always believed that early identification of problems or potential problems leads to better outcomes down the road.

Let's continue our discussion of how the key themes we highlighted earlier impacted GBDC's fiscal Q3 results. We mentioned that new non-accruals remained low. We'll come back to that point in our usual discussion of GBDC's financial results. But in brief, non-accruals as a percentage of total investments at fair value increased modestly to 2%. Net realized losses also remained low and we saw a reversal in that unrealized losses, you can see both, the low [Phonetic] net realized losses and the high unrealized gains in the NAV bridge on Slide 8.

We start with March 31, NAV per share of $13.49, that's pro forma for the dilution from the rights offering. From there, we add adjusted NII of $0.28 per share. We deduct our dividend of $0.29 per share. And you can see in the next column that realized credit losses during the quarter were very low at $0.03 per share. The big driver of the improvement in NAV per share was net unrealized gains. Net unrealized gains of $0.74 per share in fiscal Q3 reversed a meaningful amount of the net unrealized loss in fiscal Q2. Now we continue to see our job as being all about minimizing realized losses and generating more of these unrealized losses. I want to spend a little time on this call describing our approach for this task. And to do that, let me hand the microphone to Greg Robbins, who is going to offer us an update.

Gregory A. Robbins -- Managing Director

Thank you, David. Let's start by reviewing GBDC's strategic response to COVID-19 on Slide 10. Last time we talked about three key goals, GBDC has pursued while navigating the COVID-19 crisis. First, proactively managing its highly diversified first lien, senior secured investment portfolio; second, supporting existing portfolio companies through credit-enhancing incremental investments and amendments; and third, fortifying its balance sheet and preparing to capitalize on attractive new investment opportunities. We believe GBDC's strong fiscal Q3 results suggests that our strategy is working.

As a starting point, Slide 11 shows the overall composition of GBDC's portfolio as of June 30th. The data on the left shows that GBDC's portfolio remained large, diversified, granular and focused at the top of the capital structure. The portfolio adds over 250 investments with an average investment size of less than 40 basis points of the portfolio at fair value. On the right, you can see that GBDC's portfolio was designed to be resilient. We've focused since inception on lending to companies we believe we'll retain value even in a downside recession scenario. In most cases, these borrowers are also COVID-19 resistant.

Over 80% of the portfolio at June 30 consisted of investments in industries we believe are relatively insulated from COVID-19, areas like enterprise software, business services, financial services and more. By the same token [Phonetic], less than 1% of the portfolio consisted of investments in sectors we now have been particularly hard hit by COVID-19 like airlines, entertainment, hotels, energy and others. Most of our proactive portfolio management has focused on the roughly 20% of the portfolio in industry sub-sectors we identified as less insulated from COVID-19.

Turning to Slide 12, you recall that we described the three part strategy for proactive portfolio management. First, gather information; second, develop strategic plans; and third, execute those strategic plans. Over the period since March, we first gathered information and dealt with our most impacted borrowers. We're now in Phase 3 of our strategy and we are implementing game plans for each borrower, working with sponsors, management teams and junior capital lenders. This strategy is also -- and already produced meaningful results.

Our team has executed more than 50 credit-enhancing amendments. We defined credit enhancing as any amendments involving a pricing increase, improved documentation terms, or incremental equity infusion by the sponsor. Our proactive engagement with sponsors and their encouraging degree of support for their portfolio companies meant that we had only one defaults on principal and interest payments in the quarter.

Slide 13 provides two illustrative examples of the types of credit-enhancing activities we've completed and expect to complete in the coming months.

Slide 14 shows how GBDC has fortified its balance sheet. On June 30, GAAP leverage was 0.86 times, which is at the low end of our target range. Regulatory leverage was less than 0.75 times. GBDC had $435 million of liquidity in the form of cash and borrowing capacity at quarter-end. GBDC also took steps to optimize its debt capital structure. We amended the Morgan Stanley Credit Facility in late June to increase long-term borrowing capacity from $200 million to $400 million. We also fully repaid and terminated the two SLF credit facilities with Wells Fargo that were in wind down. And finally, we priced a new low cost $300 million CLO last week. As a result of these initiatives, GBDC has substantial flexibility and firepower. This flexibility and firepower puts GBDC in a great position to capitalize on attractive opportunities.

As illustrated on Slide 15, leverage levels decreased dramatically after the global financial crisis and Golub Capital was able to capitalize significantly on those opportunities. We believe recent market events will likely lead to a sustained lender-friendly environment, much like we saw from the last recession. Lower leverage, higher spreads, improved covenants and enhanced downside protection are components of what we expect to see come out of the current market environment.

And as we've discussed in prior quarters and illustrated on Slide 16, we believe GBDC has powerful competitive advantages, which will help us deliver premium shareholder returns going forward.

So with that, let me hand it over to Jon Simmons to go through our financial results for the quarter ended June 30 in more detail. Jon?

Jonathan D. Simmons -- Director, Corporate Strategy

Thanks, Gregory. As a reminder, please note that in addition to the GAAP financial measures in the Investor Presentation, we've also provided certain non-GAAP financial measures. These non-GAAP measures which we refer to as adjusted measures seek to strip out the impact of the GCIC merger-related purchase premium write-off and amortization. They are further described in the appendix of the earnings presentation. We'll refer to them throughout the conference call where appropriate, as we think they are better indicators of our performance and are consistent with how we evaluate our results.

With that, let's turn to Slide 18 to look at the results for the quarter in more detail, and I'm going to talk about the column on the right hand side of the page. Adjusted net investment income per share or as we call it income before credit losses for the June 30 quarter was $0.28, consistent with our expectations and in line with our quarterly dividend. Adjusted net realized and unrealized gain per share was $0.66. This compares to adjusted net realized and unrealized loss per share of $2.04 for the March quarter. The adjusted net realized and unrealized gain this quarter was primarily driven by the reversal of unrealized losses recorded in the prior quarter for the reasons that David mentioned in his opening remarks.

Adjusted earnings per share for the June quarter was $0.94 per share. This compares to an adjusted loss per share for the March quarter of $1.71. Our adjusted net asset value per share at June 30 was $14.05, which factors in the earnings in excess of our dividend this quarter, offset by the dilution from the rights offering. On June 29, we paid a quarterly distribution of $0.29 per share. And finally on August 4, 2020, our Board declared a quarterly distribution of $0.29 per share payable on September 29, 2020 to shareholders of record as of September 8, 2020. The distribution is consistent with our historical dividend approach of seeking to pay distributions at an annualized rate of approximately 8% of NAV.

With that, I'll hand the call over to Ross, to go through the quarterly results in more detail. Ross?

Ross A. Teune -- Chief Financial Officer and Treasurer

Great. Thanks, Jon. Turning to Slide 19, this slide highlights our total originations of $15.7 million and total exits and sales of investments of $88.4 million for the quarter ended June 30. Factoring in unrealized appreciation and other portfolio activity, total investments at fair value increased by 1% or $40.2 million. As of June 30, we had $28.3 million of undrawn revolver commitments and $80.9 million of undrawn commitments on delayed-draw term loans. This unfunded commitments are relatively small in the overall context of GBDC's balance sheet and liquidity position.

As shown on the bottom of the table, the weighted average rate of 7.5% on new investments and the weighted average spread over LIBOR of new floating rate investments of 6.3%, both increased from the prior quarter. As a reminder, the weighted average interest rate on new investments is based on the contractual interest rate at the time of funding. For variable-rate loans, the contractual rate would be calculated using current LIBOR, the spread over LIBOR and the impact of any LIBOR floor.

The top of Slide 20 shows that GBDC's portfolio remained highly diversified by obligor, with an average investment size of less than 40 basis points. The bottom of the slide shows that our overall portfolio mix by investment type has remained consistent quarter-over-quarter, with one-stop loans continuing to represent our largest investment category at 83%.

Turning to Slide 21, 97% of our investment portfolio remains in first lien, senior-secured floating-rate loans and defensively positioned in what we believe to be resilient industries.

Turning to Slide 22, the graph summarizes portfolio yields and net investment spreads for the quarter. Focusing first on the light blue line, this line represents the income yield or the actual amount earned on the investments, including interest and fee income, but excluding the amortization of upfront origination fees and purchase price premium. The income yield decreased modestly by 10 basis points to 7.7% for the quarter, primarily due to the continued decline in LIBOR.

The investment income yield or the dark blue line, which includes amortization of fees and discounts also decreased by 10 basis points to 8.1% during the quarter ended June 30, due to the decline in LIBOR. However, with most loans subject to 1% LIBOR floor of the decline in the income yield and the investment income yield were not nearly as steep as the decline in LIBOR as shown on the bottom of the slide. On the other hand because our variable rate debt facilities are not subject to a LIBOR floor, our weighted average cost of debt or the aqua blue line decreased by 50 basis points to 3.2%. As a result, our net investment spread, the green line which is the difference between the investment income yield and the weighted average cost of debt increased by a net 40 basis points to 4.9%.

Moving to the next two slides, non-accrual investments as a percentage of total debt investments at cost and fair value remained low, but increased modestly to 2.8% and 2% respectively, as of June 30. During the quarter, the number of non-accrual investments remained at 10 [Phonetic], as the disposition of two non-accrual investments were offset by the addition of two investments to non-accrual.

As David discussed in his open commentary, as a result of stronger portfolio, company performance, the percentage of investments rated three on our internal performance rating scale, decreased to 22.3% of the portfolio at fair value as of June 30. As a reminder, independent valuation firms value at least 25% of our investments each quarter. For the quarter ended June 30, the total percentage of portfolio company investments valued by the independent valuation firms was over 30%.

Slides 25 and 26 provide further details on our balance sheet and income statement as of and for the three months ended June 30.

Turning to Slide 27, the graph on the top summarizes our quarterly returns on equity over the past five years, and the graph on the bottom summarizes our regular quarterly distributions as well as our special distributions over the same timeframe.

Turning to [Slide 8], this graph illustrates our long history of strong shareholder returns since our IPO.

The next slide summarizes our liquidity and investment capacity as of June 30 in the form of restricted and unrestricted cash, availability on our revolving credit facilities, and debentures available through our SBIC subsidiaries. As Gregory just -- previously highlighted, we made some enhancements to our liability structure during the quarter, which included amendment to the Morgan Stanley revolving credit facility which increased the borrowing capacity through the full-term of the credit facility from $200 million to $400 million. In addition, we repaid and terminated the two SLF credit facilities which were passed the reinvestment periods and significantly under-levered.

Slide 30 summarizes the terms of our debt facilities as of June 30, as well as our focus on diversified long-term and stable sources of debt capital.

With that, I'll turn it back to David for some closing remarks.

David B. Golub -- Chief Executive Officer

Thanks, Ross. So to sum up, GBDC had a strong fiscal Q3. Net investment income was solid, and we made good progress executing on our post-COVID strategy. Before we turn to Q&A, I do want to be clear in saying that while we saw encouraging signs in the fiscal third quarter, we think this COVID bus trips still has a ways to go. We're worried about elevated case counts in large number of parts of the country. We're mindful of the possibility of more restrictions, perhaps even more lockdowns. We're paying careful attention to the potential indirect effects of COVID, particularly in the form of changes in consumer spending and business investment. The message we want to leave you with today is that, we've taken prudent steps to prepare GBDC for a wide range of potential scenarios. We've got a solid strategy, we've got a fortress balance sheet and we've got access to the competitive advantages of the Golub Capital platform. As a result, we think GBDC is very well positioned.

With that, let's open the line for questions.

Questions and Answers:

Operator

Thank you. [Operator Instructions] Our first question comes from the line of Finian O'Shea with Wells Fargo. Please proceed with your question.

Finian O'Shea -- Wells Fargo -- Analyst

Hi, good afternoon. Thanks for taking my question. David, first to start with the dividend payout. Looking at the model here, there is of course a few moving parts. But it looks like the way things will settle that on next quarter's equity base that the -- hurdle will no longer support the payout threshold. So you'd have to go through the dividend and that could change if you recoup some unrealized losses. Correct me if I'm wrong -- thinking about all this, but how do you anticipate your road to dividend coverage on the $0.29 level as the incentive fee kicks in more thoroughly going forward?

David B. Golub -- Chief Executive Officer

So I think you're right there, there are number of moving parts and when we set the dividend policy at $0.29, we knew there were a bunch of moving parts. I think we've made progress in fiscal Q3 in moving NAV per share up to a level that makes the $0.29 sustainable. We thought that would be the case and we're cautiously optimistic that we're going to see continued trends going forward that are supportive of that.

So I think we're on the right track here and ultimately in this period of unprecedented uncertainty, nobody can be sure of much. But I think we're on the right track toward focusing on restoring unrealized losses through unrealized gains, and in the process, increasing our NAV per share and getting to a point where that $0.29 is a level that's not only sustainable, but that we can build upon over time.

And as you know Fin, that's our history. Our history is to change dividends slowly, cautiously over time and until we got hit with COVID it was consistently in an upward direction.

Finian O'Shea -- Wells Fargo -- Analyst

Okay, that's helpful. And can you give your -- in terms of going on offense -- I appreciate [Phonetic] all the color you provided on your COVID-exposed book and you're handling of that. Obviously, you're in a pretty favorable position, originations were understandable like this quarter. But assuming that right now and going forward you're out there looking at the market. So just any high-level color on what you're seeing, is the pipeline building back up and how we should think about the opportunity and origination for you guys?

David B. Golub -- Chief Executive Officer

So, short answer is, yes, we're seeing green shoots in the M&A market, and that is leading us to be somewhat more optimistic about the prospects for increased originations in coming months. As we discussed last quarter, the early reaction to COVID-based uncertainty was a near shutdown of the M&A market and it's not surprising, buyers and sellers couldn't agree on value in the context of uncertainties that were in the market.

Sellers chose not to bring companies for sale, unless they had really strong reasons to do so. With the improved results of recent months and with a large proportion of our industries we cover, proving to be quite COVID-resistant, we're seeing an increase in M&A activity and financing opportunities. Is it back to normal yet? No. But we're seeing a striking improvement from a couple of months ago. And I think as we look at the quality of these opportunities, we're seeing that the pattern, Gregory alluded to on the call is holding which is to say post a dislocation, we tend to see opportunities that offer some combination of lower leverage, better documentation terms and higher spreads. And I think that's what we're seeing now.

Finian O'Shea -- Wells Fargo -- Analyst

Okay, that's helpful and that's all from me for now. Thank you.

Operator

Our next question comes from the line of Ryan Lynch with KBW. Please proceed with your question.

Ryan Lynch -- KBW -- Analyst

Hi, good afternoon and thanks for taking my questions. First one, kind of following up on that market environment question. You have Slide 15 that shows a good indication of how leverage levels went, coming out of the last recession. I'm just wondering if you think that this 150 [Phonetic] potentially different just given that, there is so little deal activity going on today, potentially because of this sudden stop, economic shutdown. And then at some point of recovery, which is happening today, could come on and accelerate at a pretty quick pace, once we do fully open up, we obviously don't know when that could occur versus the other downturn it was a little bit, it feels like a -- like a little bit of a slow recovery over multiple years, had really good terms and structures in companies for multiple years. I'm just wondering, if you think that this downturn or this recovery from this downturn could play out or will play out differently than the last one?

David B. Golub -- Chief Executive Officer

So, great question, Ryan and it's $64,000 [Phonetic] question. I don't think anybody really knows the answer with confidence to that. Let me give you a couple of observations. One is, it's a very rare downturn or dislocation that doesn't lead to a period of improved lending opportunities. So I think it's highly likely that we'll see an environment that's attractive for lenders going forward. The question is how attractive and how long will it last? So now let's onion [Phonetic] on what are the key factors that are going to impact, how attractive and how long it will last. Well, one of those factors is the unprecedented amount of private equity dry powder that's available out in the marketplace right now.

It is not only at record levels, but it is right now not being utilized at a pace that would be consistent with all of it being deployed. Again, if history is a good guide, and I think in this sense, it probably will be, that argues for an acceleration of private equity capital deployment once the COVID-related uncertainties ease a bit further. A third factor supporting the idea that we're going to see sustained lender-friendly terms is that we have seen a significant number of players in middle-market lending, who've been significantly hurt by COVID and whose fundraising has been hurt by COVID. And that again is fairly consistent pattern that tends to happen in downturns, and can lead to a reduced level of competition that can be -- that can be helpful.

I'm not telling you Ryan, that I think for sure, this downturn is going to look like 2009, I don't like 2009, I don't know. What I can tell you is, I think this recovery is likely to take some time due to very high unemployment rates, and at some point in the reasonably near future reductions in government spending, but this is an unprecedented period, no one has lived through a global pandemic like this before and seen this kind of government response. So we all need to plan for a variety of different scenarios. One of the themes you've heard me talk about a lot since COVID began is, is our emphasis on exactly that, I'm planning for a number of different scenarios.

Ryan Lynch -- KBW -- Analyst

Okay. Yes, that makes sense. GBDC has primarily been known as a first lien, top of the capital structure type of lender. But when you are running private credit funds, coming out of the previous downturn, you guys out of recovery phase of the prior downturn. We're willing to do more junior capital as that market became more attractive. I would assume we are probably too early in the recovery phase for QVC [Phonetic] to be considering that strategy. But is that something or can you give me some commentary on your willingness to pursue that strategy at all, further coming out of this downturn in GBDC if the opportunity arises?

David B. Golub -- Chief Executive Officer

Well, you said two things there. So let me see if I can parse it a little bit. Do I think that in the near term that Golub Capital BDC is going to change its core strategy away from senior debt, first lien debt toward junior debt? The answer to that is no. I think it's highly likely that we're going to sustain our focus on first lien and one stops.

Second part of the question was, would we ever consider deploying a portion of our capital base, a meaningful portion of our capital base in junior debt? And I would not say never to that, because as you point out, we have a quite successful history as an organization in investing in junior debt in the right market situations. I just -- I don't think we're there right now.

Ryan Lynch -- KBW -- Analyst

Okay, fair enough. Post the equity raise, your balance sheet seems to be in really good shape. You guys have a lot of dry powder. That said, are you guys considering, are you guys evaluating changing your liability structure at all, principally pursuing a portion of that in unsecured debt going forward?

David B. Golub -- Chief Executive Officer

Sure. So, I'll give an answer similar to the answer I think I gave last quarter on this. We've said on a number of prior earnings calls that we're big believers in the benefits of unsecured debt. And we think that it makes sense to add a layer of unsecured debt into GBDC's liability structure over time. As you pointed out, we have the luxury right now of -- lot of liquidity, so we're in no rush. We are operating at the low-end of our leverage targets. Our plan is to time the introduction of unsecured debt appropriately so that we're doing it on attractive pricing and other terms.

Ryan Lynch -- KBW -- Analyst

Okay, fair enough. Those are all my questions. I appreciate the time this afternoon.

Operator

Our next question comes from the line of Robert Dodd with Raymond James. Please proceed with your question.

Robert Dodd -- Raymond James -- Analyst

Hi guys. Yes. Ryan, just partly asked out of mind, I'll [Phonetic] expand it a little bit, I mean to that point, I mean portfolio looks to be in a good shape, given the environment we're in. So looking at the liability side, and I appreciate the answer you just gave David. But when I look to -- you've got two of your bank facilities leaving the investment period, not maturity, but the investment period in the first quarter of next year. So would it be reasonable to expect that maybe the unsecured would come in ahead of that? Or is that just not a factor, and you're just going to currently expect to just extend those facilities and reinvestment time frames?

David B. Golub -- Chief Executive Officer

The answer Robert is, we have great relationships with our bank partners. I have enormous confidence that if we thought the right answer was to extend those facilities, we would have no problem being able to do so, as we recently extended one of those facilities, the Morgan Stanley facility. The question is not can we, the question is what's the optimal capital structure for GBDC. And the tricky piece here is that the timing of unsecured issuance is surprisingly important. This is long-term fixed rate debt and pricing on it has changed very dramatically, just in the last couple of months. So we want to be very smart about how we do it. As you know, last week we priced a new securitization for GBDC. The pricing on that was a new post-COVID low [Phonetic] for securitization financing our AAAs were LIBOR plus 235 [Phonetic]. So one of the ways we've made money for shareholders over time is by keeping our liability costs very low. And we're intent on accomplishing two goals simultaneously, one is adding unsecured to the stack and the second is maintaining very low liability costs.

Robert Dodd -- Raymond James -- Analyst

That's completely fair. And yes, the CLO price does look quite attractive. I mean, the other part, obviously, it ties into it, is having underutilized. If you do add unsecured and then you have four credit facility revolvers that end up underutilized those become a little expensive, to your point that you just terminated the two SLFs, because they weren't efficient anymore. So from that perspective, I mean, we do expect to continue running four credit facilities, if and when unsecured gets added to the stack anything, any color on that? About what the optimum number or size of revolver capacity is for the business?

David B. Golub -- Chief Executive Officer

Yes, I mean, I think if you flash forward to a period when we -- when we have a capital stack that includes unsecured, it probably has fewer bank revolving credit facilities, and a smaller total amount of bank revolving credit facilities.

Robert Dodd -- Raymond James -- Analyst

Got it. I appreciate that. If I can set a different topic, you talked about green shoots starting to emerge for this -- deployments.

David B. Golub -- Chief Executive Officer

M&A.

Robert Dodd -- Raymond James -- Analyst

And you've got plenty of liquidity right now. Can you give us any -- mostly looking at add-on acquisitions, potentially platform acquisitions, I mean, because obviously, an add-on maybe the due diligence is easier in a environment, where I certainly haven't gone on a plane since March. And we know versus an add-on where the due diligence may need to be more expensive in nature and may require travel. I mean, can you give us any color on -- on the type, how the due diligence is being done, etc.?

David B. Golub -- Chief Executive Officer

Yes, it's a very good question. So let's just broaden your question and talk about what's the deal environment of the future going to look like? And first, let's contextualize, if we look at the past for Golub Capital BDC, and I don't think we're terribly different from Ares or some of the other very large platforms. About half of our deal activity has historically been with existing borrowers. And you're 100% right, that if you think about doing deals in the COVID era, it's a lot easier to do deals with existing borrowers than it is with companies you don't know. You already know the management team, you already know the company, you've already got a relationship, you've done detailed in-person due diligence in the past, it's just much easier. So absolutely, existing portfolio is going to be a significantly higher than usual proportion of new deal activity going forward.

Having said that, I think, there will be some new platform activity and it will be with sponsors who we know well, and industry sectors that we know well, because you can't do perfect diligence in today's environment for all the reasons you're just alluding to. I think that creates a new source of competitive advantage for dominant players like us. We have the really close relationships that you would want to have with the top sponsors in this environment. We have deep industry knowledge and domain expertise in a number of areas, including software, including franchising businesses, including some parts of healthcare, that are particularly attractive in this -- in this post-COVID world. So I think your questions are really good question, Robert, I think at least in the near-term, post-COVID investing activity is going to look a bit different from pre-COVID investing activity, and it's going to give particular advantages to some players over others.

Our next question is a follow-up from the line of Ryan Lynch with KBW. Please proceed with your question.

Ryan Lynch -- KBW -- Analyst

Hi, I just had one more question. I know historically, you guys have never really used unsecured debt on your balance sheet. But David, you mentioned you were never against, you're always going to utilize that at the right time. I'm just curious why was there never even the desire or the ability to get an investment grade rating from one of the major rating agencies, just to have that on file, in case you guys did look to -- if the markets became attractive enough, that you guys could pursue that a little bit easier, given your guys -- you guys have a great historical track record, defensively positioned portfolio. Why was that rating never pursued or achieved in the past?

David B. Golub -- Chief Executive Officer

I don't want to spend a lot of time going into the past other than to tell you that, we did book into unsecured offerings in great depth, including being in discussions with rating agencies. So I don't think your premise is correct, that it's something that we didn't or couldn't do. But I think, the key point is, we are where we are. So we are in a position where I look at our balance sheet and I think we're in a very strong position. We've got a lot of liquidity and we've got the opportunity if it makes sense to pursue an unsecured offering prospectively.

Ryan Lynch -- KBW -- Analyst

Okay. Thanks for the follow-up.
