Hey Mike, thanks very much. And welcome to all the participants. I'm very pleased actually today to report that Gladstone Investment had another strong fiscal quarter and a very good year into 3/31/18. We were able to increase our net asset value, which is our book value, from $10.37 a share in the third quarter to $10.85 a share in the fiscal year-end, and for the 12 months from 3/31/17 to 3/31/18 by $0.90 per share or from $9.95 to $10.85 per share.
We also experienced a 10.8% growth in our adjusted net investment income year-over-year from $0.74 per share to $0.82 per share. And I'm very happy with these results as year-over-year is a good indicator of the achievement of our plans and growth as we think of our business on an annual basis as we can experience reasonably significant swings quarter-to-quarter. So the year results are important. And based on these results, in April, we were able to announce an over 3% increase in our annual distribution rate to common stockholders from $0.78 to $0.80 a share. We also were able to announce continuation of our semiannual supplemental distributions program with a payment of $0.06 per common share to be made in June of 2018. We fully expect that a significant portion of these supplemental distributions will be made from capital gains.
In addition to that, we've seen our stock price increase year-over-year, such that the total 1-year return on investment was around 22%, and this includes the reinvestment of dividends, which has significantly outperformed the Wells Fargo BDC Index, which was actually minus 9%.
Now the increased stock price is encouraging as I do believe the market is beginning to recognize not only the growth in the income and distribution that we've been having, but also the value of the equity component in our buyout business model.
We keep stressing that we do have a differentiated investment strategy and the business model from other BDCs, in that our investments are a majority of equity and debt capital in the buyouts of U.S. businesses. These companies generally have earnings before interest, taxes, depreciation, amortization, or as we call it EBITDA, generally in the range between $3 million and $20 million. And the structure, importantly, that we use for funding these buyouts consists of the direct equity investment for significant ownership position, which is then in combination with a secured first- or second-lien debt that we also provide. This is a differentiator to us from traditional credit-oriented BDCs, in that the target proportion of equity to debt for the investments in our portfolio is in the range of 25% to 30% equity and roughly 75% to 70% debt at cost. And when compared to most other credit-oriented BDCs and their portfolios, you'll find that typically it's more around 10% equity and 90% debt. So therefore, the interest and the success fees on the debt portion of our investments are able to provide this sort of steady income, which pays an over time, grow our monthly distributions as we've been able to do certainly in the past. And as I mentioned earlier, again, in April, we were able to increase our monthly distributions to an annual run rate of $0.80 per share.
Secondly, with the significant equity positions that we own in each portfolio company, we do look for an increasing value, so that an increase in the equity does provide capital gains and other income over the life of the investment or when we actually exit that investment. So these potential cap gains and other income may then be distributed to our stockholders in the form of these supplemental distributions and the program that we started. And so to this point, we paid the first 2 of such planned supplemental distributions in the amount of $0.06 per share to common stockholders in each of June and December 2017. And then in April of this year, we declared this other 6% distribution, which will be paid in June of 2018.
Third, this differentiated investment approach of being a provider of the significant portion of the equity, usually the majority, and most of the debt in our transactions gives us this advantage that we believe to typical lenders and credit-oriented BDCs, in that we are able to have some influence over the companies that we buy. Thus, not only by limiting the risk of our debt being refinanced, but also where we have participation and an involvement with management, which provides an interaction with the company, which is similar to a traditional private equity fund and extremely important in terms of preserving and building value over time.
Now let's take a quick look at sort of our historical performance, our scorecard, so to speak. And I'd like just to look at this from the period of 3/31/14 to 3/31/18, so essentially, a 4-year period of time. What have we done then? Well, we've grown the total assets from about $331 million to about $611 million at fair value. The debt portion of our investments at cost have grown from about $279 million to almost $432 million. This is what supports the growth in our regular monthly distributions per common share, which has gone from $0.71 per share in fiscal year '14 to $0.77 in fiscal year '18, and then the ability to have this recent increase to $0.80 per share annually in April of 2018.
In addition, the equity portion at cost has grown from about $105 million to about $153 million. Our net asset value, again, or equity, if you will, has increased from $8.34 a share to $10.85 over that same 4-year period. We had -- at 3/31/18, we have 33 companies or -- at that point, 33 companies in our portfolio. And from inception in 2005 when this company was taken public through the 3/31/18 period, we have exited 12 buyout companies, with these exits having generated over $85 million in net realized gains and about $22 million in other income on exit.
These exits achieved an aggregate cash-on-cash return on the exit of the equity portion of those investments of approximately 3.3x. So again, the equity aspect of our business model is very important, and we're proving it out.
And it is this equity growth and exit activity that has allowed us to deliver on our objective of generating cap gains from the equity portion of our assets, which we will look to continue in the future.
So going forward, and as certainly as we continue with new buyouts and building our investment portfolio, we must also manage, as I keep saying, the sales turnover, if you will, or when we exit some of these companies in the portfolio, which needs to be consistent with our strategy of providing realized capital gains from the equity portion of our portfolio. Clearly, we need to be guided by market conditions, so we'll always be assessing the risk and return, continuing to hold an investment versus exiting it or selling it and remain sensitive to preserving our portfolio of assets to help and continue producing the income for our monthly distributions.
Now as we grow, and we've talked about this in the past a bit, we must consider raising equity capital, which we try to do in a responsible manner. Since our IPO and since 3/31/2018, we have raised equity in 3 secondary market transactions, and in each of those where the net price after commissions and discounts was below NAV at the time. From March until early May of this year 2018, we raised approximately $3.1 million of net proceeds under our at-the-market or ATM offering, which in the aggregate though resulted in net prices at or above NAV at the time. So that's just good progress. And we have been able to invest the proceeds over the periods of time from these various offerings very constructively as we have been able to grow our NAV while generating capital gains, and we will strive for this going forward.
So our new buyout generation activities have a high priority, and it is a key element, obviously, to our growth. We will maintain strict adherence to investment fundamentals and a thorough due diligence process, which has enabled us to provide shareholder returns in both our consistent regular monthly distributions as well as the supplemental distributions.
In this regard, we made 2 new buyout investments, aggregating about $59 million in fiscal 2018. And subsequent and right at the year-end, in April, we invested about $29 million to form our most -- our latest investment, Bassett Creek Restoration, Inc., which is an acquisition platform for businesses in the restoration and renovation services space, which simultaneously acquired a company called J.R. Johnson as its first operating business.
So we continue reviewing and conducting due diligence on a number of new potential investments. In addition to new stand-alone acquisitions, we are actively pursuing accretive add-on investments for some of our existing portfolio companies. And during 2018, we made add-on investments in Nth Degree and Schylling, both very good add-on investments, and those 2 companies are performing exceptionally well. And we look forward to this continuing to build assets within the portfolio, while accelerating the value creation of each of these individual companies.
We continue to operate in a buyout environment, however, where the competition for new investments is elevated, purchase prices being paid are very high, and it is a challenge to close deals, given our conservative value approach and the expected -- and our expected financial returns. Case in point, our latest investment in Bassett Creek was at a value, which we believe is consistent with our expectation of returns, while we frankly passed on a number of other opportunities that were just much higher values than we thought warranted.
So this really kind of illustrates what may seem and could look like a low rate of production of new investments over the past year. However, when we make investments, not only is it a relatively lengthy time frame from the point of finding a good opportunity to actually closing the investment, but we -- as we strive for quality to build value in both income and equity, we cannot be volume driven as we might be if we were actually building a portfolio of loans, which is not the business that we're in.
So our return target for our equity investments is to provide a minimum 2 to 3x cash on cash. The debt investments, which go along with it, are generally secured and primarily first-lien loans and typically carry a cash yield in the low to mid-teens. These debt cash returns help to balance the equity portion of our investment, thereby producing a blended current cash yield, which supports our stockholder distribution expectations. The debt, typically, also has a success fee component, which is a yield enhancement and is generally contingent on a change of control, such as the sale or an exit for us to receive it. However, in certain circumstances, a success fee may be paid in advance at that portfolio company's option. Our investment focus is generally in companies that have good EBITDA and operating cash flow, usually in the areas such as light and specialty manufacturing, specialty consumer products and industrial products and services are the main areas that we focus on.
So again, just to briefly recap, our investment activity for fiscal 2018, we made 2 new buyout investments during the year and 1 subsequent and right at year-end in April. We invested another $39 million in follow-on investments as a result of some of those add-ons I mentioned. And we also actually received back $40 million repayments and sale -- through sales, including the exit of 2 buyout investments at a gain.
So what's our outlook? Well, we'll continue executing our plan. We will be continuing to add accretive investments to grow both the income-generating portion and the equity portion of our assets, while positioning the companies in the portfolio for potential exits, thus, maximizing distributions to stockholders. We anticipate paying our semiannual supplemental distributions as the portfolio continues to mature, and we are able to manage the exits and therefore, realize capital gains. So these distributions, again, are generally expected to be made from undistributed net cap gains and undistributed net investment income. We and our Board of Directors will make the determination for the amount and timing of such semiannual supplemental distributions as we continue to execute on our strategy.
So with that, I'll turn it over to our CFO, Julia Ryan, who will go into some more of the detail on the actual financial performance for the quarter and the year. Julia?
