Hey, Mike. Thanks very much, good morning to all our shareholders and participants on this call. We're pleased to again report solid operating results for the most recent quarter ending 12/31/2019, that our adjusted net investment income of $0.23 per common share was consistent with the last quarter and was greater than our regular quarterly distribution of $0.20 per common share. Based on our current portfolio performance, the valuations and income-generating potential, the outlook for the balance of the fiscal year ending 3/31/2020 is strong. In particular, when considering the past three fiscal quarters where we have already generated adjusted net investment income of $0.71 per share. During the quarter, we made incremental investments in existing portfolio companies to support add-on acquisitions, we exited two buyout investments during that quarter also.
With these exits, since in our inception in 2005, we've actually exited 21 portfolio companies and generated an overall 4x cash-on-cash return on the equity portion of those investments. Again, with our thesis of making equity investments and also generating income for shareholders. Along with this exit activity, we have continued to grow total assets and the monthly distributions to shareholders over that period. Our NAV also remains strong at $12.51 per share at 12/31/2019. As we plan for the future and look to our long-term capital needs, we determine that with the strong performance of our common stock price and the resulting dividend yield, that it would be wise to raise some common equity.
In January, we began selling common stock under our new ATM program, and to date, we have raised net proceeds of about $3 million, all above Net Asset Value, which is accretive to our existing shareholders. We will continue this program so long as we determine it is positive for shareholder value and our overall cost of capital. During the 12/31/2019 quarter, we maintained our monthly distributions at an annual rate of $0.82 per common share for the quarter. Subsequently, in January, our board declared a 3%, increase to $0.07 per common share for our monthly distributions or an annual run rate of $0.84. Reflecting additional capital gain realization successes during the calendar year, we made another supplemental distribution of $0.09 per common share in December. Just briefly on the outlook, the buyout environment continues to be very competitive.
The good news, though, is that we are seeing a pickup in new investment activity, and we're very much involved on a daily basis in reviewing and analyzing new investment opportunities that fit our profile. As mentioned, we made two new acquisitions, several add-ons in the fiscal year to date, and as I mentioned, evaluating a number of other potential opportunities. We anticipate continuing to pay the semiannual supplemental distributions as the portfolio matures and grows, and we're able to manage exits and realize additional capital gains. Of course, we and our board of directors will evaluate that ability to make these additional supplemental distributions, their amounts, and the timing, as well as any further deemed distributions of capital gains, which would be similar to the one that we declared in fiscal 2019.
On that basis, I'm going to turn it over to our CFO, Julia Ryan, to give you more detail of the actual financial performance for this past quarter. Julia?
Thanks, Dave. Let me start with a summary of the fund's financial performance. We end the December quarter with NII of $6.2 million, which compared to NII of $6.6 million in the prior quarter. Investment income declined slightly due to a $2 million decrease in interest income, which was primarily driven by the collection of past due amounts upon the exit of one portfolio company in the prior quarter, which was offset by $1.4 million of an increase in other income, which can be variable. Net expenses decreased slightly compared to the prior quarter, which was primarily driven by a decrease in other expenses, most notably excise taxes and interest expense, given the pay-down of our credit facility with proceeds from exits, as well as an increase in credits to fees from the advisor.
This decrease was partially offset by a $0.8 million increase in the income-based incentive fee due to higher pre-incentive fee net investment income, and a half million dollar increase in the capital gains based incentive fee given net realized and unrealized gains this quarter. When adjusting net investment income to exclude the capital gains based incentive fee accrual, adjusted NII for weighted average common share was $0.23 in the current quarter. We continue to believe that this metric is a useful and representative indicator of operations exclusive of any capital gains based incentive fee, as net investment income does not include those realized or unrealized investment transactions associated with this fee. During the quarter ended December 31, 2019, we recognized a net realized gain on investments of $34 million, which was primarily a result of those two exits.
On the balance sheet and liquidity side, as of December 31st, total assets decreased to $582 million, compared to about $620 million at the end of September, because repayments and exits exceeded disbursements to existing portfolio companies and due to a roughly $1 million decline in the existing portfolio. Liquidity remains strong with almost $170 million available under our credit facility and an asset coverage of 384%. Net assets totaled about $410 million or $12.51 per common share as of December 31st, compared to $12.39 per share at September 30th. Primarily a result of realized gains exceeding unrealized depreciation, which includes the reversal of previously recorded unrealized appreciation or depreciation upon exits and the impact of distributions made during the quarter. As of December 31st, on a book basis, undistributed net investment income, combined with net realized gains, totaled almost $58 million or about $1.76 per common share.
This amount is net of the $50 million deemed distribution we declared for the fiscal year 2019, and also reduced by the book accrual of the capital gains-based incentive fee, which is roughly $24 million, of which only $8.1 million is contractually due currently. All else equal, the $1.76 per common share would be available for distribution to shareholders in future periods, even if the entire capital gains-based incentive fee accrual were to be paid to the advisor. With that in mind, and as previously announced in January, our board of directors increased monthly distributions to $0.07 per common share for the first calendar quarter of 2020.
Assuming this monthly distribution run rate of $0.84 per share per year and estimating $0.18 per share in supplemental distributions, which have not been yet determined or declared, annual distributions total $1.02 per common share, which is roughly a yield of 7.7%, based on yesterday's closing price of $13.30. This covers my part of today's call, and back to you, David.
Okay. Thank you, Dave, Julia, Michael. All good information to our shareholders. That presentation and the 10-Q filed yesterday should bring everyone up to date. The team has reported, I think, excellent results, including add-on investment transactions and exit activity with significant net realized gains. I did see one of the large brokerage houses that has a list of BDCs they follow. GAIN was number 2 on their list with regard to the last 12 months total return. That was 58.2%. That's quite significant. Some of that's due to the fabulous time that we're in today. Fantastic returns come from good times. If you can't make it now, it'd be hard never to make it.
My own view of this is we have a great team that's running this company now, and we're in the best position that we've ever been in, and I think the future looks tremendous. The team is in a good position to continue the successes that they've just reported today throughout our fiscal year ending March 31st, 2020 and longer. I hope it goes for another year as well. We believe Gladstone Investment is an attractive investment for investors seeking continuous monthly distributions and supplemental distributions from potential capital gains and other income. The team hopes to continue to show you a strong return. At this point, we'll stop and have some questions from our analysts and shareholders about what you heard today and seen in our 10-Q that was filed yesterday. Sarah, would you come on and tell them how they can ask questions?
Certainly. As a reminder, to ask a question, you will need to press star then one on your telephone. To withdraw your question, please press the pound key. Again, that is star then one if you would like to ask a question. Please stand by while we compile the Q&A roster. Our first question comes from the line of Mickey Schleien with Ladenburg. Your line is now open.
Yes. Good morning, everyone. I just have one question today about capital allocation. Dave, I do appreciate that you noted that the pipeline looks healthy, and I obviously realize that issuing equity at the current stock price is nicely accretive to NAV. Why not use your available debt capital instead, since it's meaningfully cheaper than common equity and your leverage is still quite low?
Mickey, again, I think as we've talked many times, I think about capital and availability sort of being somewhat fungible. The decision around raising some equity through the ATM, frankly, was less driven by our immediate capital needs as much as really taking a longer view and thought about who knows what the world is going to look like in the next 9-12 months. We're in a wonderful position to be able to shore up our capital base and especially our common equity base, without diluting shareholders, and as you point out, actually being somewhat accretive. The objective is not to go and raise a slew of equity at this point, because we need to put it to work. We thought it was a relatively effective way to do it.
The cost of that equity, if you look at the relative yield based on the dividend that we're paying out and will continue to pay out on the common stock price at the current levels. Of course, if they start to decline for whatever reasons will be, as I mentioned, very careful in how we do that. Again, somewhat opportunistic in terms of a good way of thinking about the corporate finance of this company and the relative ability to relay in, if you will, some fairly low-cost equity. That's sort of a long answer, Mickey, but it's really more about that.
The good news, to your point, is we have lots of availability and indeed, as we move forward with new investments, we'll be able to access that availability both really through our line of credit that we have and frankly, also some excess cash that we have that as a result of the gains that we've generated. That's basically the answer.
Okay. I understand, Dave, and just one follow-up question that came to my mind. Gladstone as a platform has particular expertise in manufacturing industries. I know it's early days, but have you started to formulate your thoughts on how potentially the coronavirus could impact some of your borrowers, given that some of them may be importing materials or supplies from China?
We do have a few companies that do indeed import product from China. I will say that it's not just the coronavirus, but obviously we've been working with all of these companies and more importantly, they have been working internally themselves based on the tariff issues and so on, which have had some impact on a lot of companies, not necessarily ours, but as we know, across the board. I would say this, that a couple of them have worked and prior to the coronavirus, they even moved some production to places like Vietnam, et cetera. Yeah, I think we anticipate to see some effect, but at this point, I'm not hearing from any of our CEOs of our manufacturing companies that do indeed manufacture in China or import that right now there's a significant impact.
It's possible that it could have a slowdown on product coming in.
I understand. That's it for me this morning. Thank you for your time, Dave.
Thanks, Mickey. Next question.
Thank you. As a reminder, to ask a question, you will need to press star then one on your telephone.
We have any other questions, please come on board.
We do have a question from the line of Mark Farron, individual investor. Your line is now open.
Hey, guys. Another fantastic quarter. It was nice to hear Julia talk about the total dividend return being at about $1.02 a share. As far as the effect of China on companies like SOG, et cetera, you sound like it's pretty minimal. Are there any other things you're watching out for in the future? Thank you.
Nothing other than the economy in general. We're seeing a very reasonably good economy with most of our manufacturing companies. Everyone's predicting, been talking about a recession, of course, and we haven't really started seeing that yet. All the inputs I'm getting from our CEOs is, again, being very careful, conservative. Lots of moves towards more automation. Main issues we all run into in a lot of our companies are around getting and hiring and keeping good qualified employees. Moves to higher automation is one important thing. Generally, I think all the usual basics for all the businesses we have to look at are kind of what we focus on.
All right. Thank you, Dave. You guys and girls are doing a great job as always. Thank you very much.
Another question?
We do have a question from the line of David Cobza, individual investor. Your line is now open.
Thank you. Hello. My name is Dave Cobza, I just called to express my thanks and gratitude for your performance, for your team. I initiated my position in Gladstone Investment about five years ago, I have an average cost basis of $7.25, I own 15,500 shares. I rely on this investment income along with a few other companies, for my monthly income. I'm most grateful. Out of the companies that I own, including a few other BDCs and some other companies, I can say that Gladstone Investment Corporation is far and away the best investment that I've owned. Again, thank you so much, I'm most grateful, may our Lord and Lady bless and keep you always. Thank you.
Well, thank you for that nice compliment, and we appreciate people who are holders and like our monthly dividends. Do we have another question?
We have no further questions at this time.
All right. Well, thank you all for calling in. We appreciate the time together, and we'll see you next quarter. That's the end of this call.
Ladies and gentlemen, this concludes today's conference call. Thank you for participating. You may now disconnect.
