Analyst · Compass Point
Thank you, Chris. Slide 4 highlights our key performance metrics for the quarter ended February 28, 2018 and our usual presentation of this data. Across all these metrics, this quarter again shows the positive impact of increased assets we have always spoken about. When adjusting for the incentive fee accrual related to net unrealized capital gains and the various impacts of the refinancing of the 2020 baby bonds in last year's numbers, adjusted NII of $3.8 million this quarter was up 15.5% from $3.3 million last quarter and up 31.3% from last year's Q4. Adjusted NII per share was $0.60, up $0.06 from $0.54 last quarter and up $0.11 from $0.49 last year.
The increase from last year reflects our higher level of investments and resultant higher interest income, with AUM up 17% from last year. The sequential quarterly increase was primarily due to additional interest income from accelerated OID on certain early repayments, as well as additional other income earned from prepayment penalties and increased originations compared to last quarter.
These factors led to adjusted NII yield of 10.7% for the quarter, up 190 basis points from 8.8% last year and up 110 basis points from 9.6% last quarter.
In addition, we experienced a net gain on investments of $2.2 million for the quarter or $0.35 per share, resulting in a total increase in net assets resulting from operations of $5.5 million or $0.89 per share. The $2.2 million net gain on investments was comprised of $0.2 million in net realized losses and $2.4 million in net unrealized appreciation. The unrealized appreciation includes $1.3 million related to our Taco Mac Restaurant Group investment, restructured subsequent to year-end.
Moving on to Slide 5, you will find our 12-month key performance metrics for our fiscal year with comparable periods. When looking at our numbers on an annual basis, the strength of our performance over the longer term becomes apparent, eliminating any quarterly lumpiness. Year-over-year, all of our metrics are up. Adjusted NII is up 18.5% to $13.7 million; adjusted NII per share is up $0.26 to $2.27 per share; and adjusted NII yield is up 110 basis points to 10.2%.
As we've always reiterated, return on equity is an important performance indicator, including both realized and unrealized gains. Return on equity was 13.2% for the year, up 420 basis points from 9.0% last year and up 380 basis points from 9.4% for fiscal year 2016. This figure also easily beats the current BDC industry average of 8.5%.
A quick note on expenses. Total expenses, excluding interest and debt financing expenses, base management fees and incentive management fees, increased slightly from $4.3 million last year to $4.8 million this year, but it remained consistently at 1.4% of average total assets for both years. This increase is primarily due to: one, increased professional fees from this year's Sarbanes-Oxley control activities now that the company is an accelerated filer and requires an audit opinion over the control environment, which by the way was a clean, unqualified audit opinion issued by E&Y for the year; and two, increased administrator expenses pursuant to the administrator agreement. For the quarters ended February 28, 2018 and 2017, these total expenses remained relatively unchanged at $1.2 million.
The additional KPI slide and net interest margin analysis is again included on Slides 29 to 52 in the appendix, highlighting our BDC's strong performance and continued increased results. Fiscal '18 is of particular note, demonstrating the earnings power of the most recent AUM growth as our cash and SBA debentures were further deployed during the year.
As you can see on Slide 6, NAV this year was $143.7 million as of year-end, a $16.4 million increase from NAV of $127.3 million last year and a $5.1 million increase from $138.8 million last quarter. NAV per share was $22.96 as of year-end, compared to $21.97 as of last year and $22.58 as of last quarter.
NAV changes for the year includes $12.7 million in net investment income and $4.9 million of net realized and unrealized gains earned, offset by $11.4 million of dividends declared. In addition, $2.4 million of stock dividend distributions were made through the DRIP, and $7.7 million of net share sold through our at-the-market equity offering.
In addition, our NAV increase is net of a $7.7 million realized write-down of our legacy My Alarm Center investment, partially offset by $1.8 million in other realized gains, mainly from the sale of our Mercury Network investment in Q2.
Net unrealized depreciation for the year was due primarily to $1.9 million unrealized depreciation on our CLO equity investment; $1.9 million unrealized depreciation on our Easy Ice preferred equity investment; $2.6 million unrealized depreciation on our Elyria equity investment; and net unrealized depreciation being adjusted to 0 to reflect the recognition of the net realized loss on the 2 realizations above.
Our net asset value has steadily increased since 2011, and we continue to benefit from our history of consistent realized gains.
Moving on to our waterfall Slide 7, you will see a reconciliation of the major changes in NII and NAV per share on a sequential quarterly basis. This helps break down the numbers into a couple of more manageable variances.
Starting at the top, NII per share increased from $0.54 per share at Q3 to $0.60 per share at Q4. The significant movements were a $0.05 increase in total interest income, primarily from increased prepayment penalties and accelerated amortization of OID, resulting from early repayments. As this slide shows, a higher weighted average shares outstanding had a $0.02 dilutive impact and all changes are shown net of incentive fees.
Moving on to the lower half of the slide, this reconciles NAV per share from $22.58 at Q3 to $22.96 for this quarter. The $0.53 generated by our GAAP NII for the quarter and a $0.59 net appreciation on investments were offset by the $0.49 dividend declared for Q3, with a Q4 record date as well as a $0.05 dilution from an increased share count.
Slide 8 outlines the dry powder available to us as of year-end, which is $71.1 million in total. This is spread between our available cash, undrawn SBA debentures and undrawn Madison facility. All our borrowings, except for our Madison facility, is fixed rate debt in this rising interest rate environment, with at least 6 years of maturity remaining.
We are pleased with our liquidity position, especially taking into account the overall conservative nature of our balance sheet and the ability we continue to have to grow our assets by 21% without the need for external financing.
At the same time, almost 80% of our investments have floating rates and although they have LIBOR floors, we are through all of them already, which means we will be a big beneficiary of rising short-term rates.
As you can see on Slide 9, we have analyzed the potential impact of changes in interest rates on interest income from investments. Assuming that our investments as of year-end were to remain constant for a full fiscal year and no actions were taken to alter the existing interest rate terms, a hypothetical change of 100 basis points in interest rates would increase our interest income by approximately $2.3 million. This is all incremental to our existing earnings without any other changes.
Now I would like to move on to Slides 10 through 12 and review the composition and yield of our investment portfolio. Slide 10 is our usual slide highlighting the portfolio composition and yield at the end of the fiscal year. Both our composition and weighted average current yields remain relatively consistent with the past, with $342.7 million invested in 30 portfolio companies and 1 CLO fund, and approximately 58% of our investments in first lien.
On Slide 11, you can see how the yield on our core BDC interest-earning assets excluding our CLO and syndicated loans, as well as our total portfolio yield, has remained consistent, around 11% for the past several years despite high levels of repayments and the need to continue to replace these assets. Our core BDC asset yield increased slightly, reflecting increased 1- and 3-month LIBOR rates, offset by slightly tighter spreads. Year-over-year, the CLO yield has increased significantly as the CLO term moves closer to the end of its reinvestment period in October 2018.
Turning to Slide 12, during 2018, we made investments of $107.7 million in 5 new and 9 existing portfolio companies and had $66.3 million in 8 exits and repayments, resulting in a net increase in investments of $41.4 million for the year. Our investments remain highly diversified by type as well as in terms of geography and industry, spread over 10 distinct industries with a large focus on business, consumer and healthcare services. We continue to have no direct exposure to the oil and gas industry, a fact that has served us extremely well.
At other total investment portfolio, 8.7% consists of equity interest. Equity investments remain an important part of our overall investment strategy. As you can see on Slide 13, realized losses this year was $5.9 million, primarily from the $7.7 million loss on our My Alarm Center investment we have previously discussed.
Despite this onetime loss, for the past 6 fiscal years, we had a combined $11.8 million of net realized gains from the sale of equity interest or the sale or early redemption of other investments. This consistent performance reflects the quality of our portfolio credit, has helped grow our NAV and is reflected in our healthy, long-term return on equity.
That concludes my financial and portfolio review. I will now turn the call over to Michael Grisius, our President and Chief Investment Officer, for an overview of the investment market.
