Scott Bluestein -- Chief Executive Officer and Chief Investment Officer

Thank you, Michael, and thank you all for joining us today. 2021 was a transformative year for Hercules Capital, and I am incredibly proud of what our team accomplished. Our record-setting performance in 2021 culminated with the strongest originations quarter in the company's history and the recent declaration of a new increased supplemental distribution program for our shareholders. Hercules Capital was able to deliver yet another strong year of outstanding originations performance, solid financial results and strong credit performance.

In addition, 2021 marked the establishment and launch of our new private credit business under our wholly owned registered investment advisor subsidiary, which has significantly expanded our platform capabilities and should help drive enhanced total shareholder return over time. We took additional steps in 2021 to further strengthen our balance sheet, enhance our funding flexibility, and drive down our cost of capital, which will allow us to continue to demonstrate to our existing and new borrowers the importance of having a partner with a strong and stable balance sheet and our ability to grow with these companies as they scale. In 2021, the health and vibrancy of the VC ecosystem, continued strength and expansion of our origination platform and capabilities, robust liquidity position and strong balance sheet put us in position to deliver achievements on multiple fronts, including record total gross debt and equity commitments of $2.64 billion, up 122% year-over-year and our fourth consecutive year with over $1 billion of new commitments; record total gross fundings of $1.57 billion up 106% year-over-year; increased our base distribution to $0.33 per share; record cash distributions of $1.66 declared for 2021, a 23% year-over-year increase; record undistributed earnings spillover of $192.1 million or $1.65 per share based on ending shares outstanding; closing our first index-eligible public offering of $325 million, 2.625% notes; a record 40 portfolio company IPO and M&A events; and finally, over $225 million of investments assigned to and/or funded directly out of the new advisor funds that we manage through our wholly owned RIA. As much as it was a year that showed the true strength of our brand, reputation and world-class originations team, it was also an important year of investments in the company that we believe will lead to further growth in our platform and ultimately to enhance total shareholder returns.

Let me recap some of the key highlights of our performance for Q4. We originated a record of over $948 million of gross new debt and equity commitments, an increase of over 32% from our previous quarterly record and delivered record gross fundings of over $503 million, an increase of 17% from our previous quarterly funding record. Our technology and life sciences teams both turned in exceptional performance in Q4. Our funding activity was balanced between our two core verticals with a slight weighting toward life sciences investments during the fourth quarter.

For the full year, our funding activity was split nearly evenly between our technology and our life sciences verticals. This unique portfolio balance and diversification strategy affords Hercules the ability to navigate the market irrespective of the macro environment. In addition to strong funding activity for new portfolio companies, we were also able to expand our funding relationship with numerous portfolio companies that continue to show strength and achieve performance milestones during the quarter. Given the magnitude of our new commitment activity during 2021, we expect this trend of increased follow-on fundings to existing portfolio companies to continue in 2022.

The momentum that we saw throughout 2021 has carried into 2022, and we are pleased by our performance on originations quarter-to-date. Since the close of Q4 and as of February 18, 2022, Hercules has already closed $238.5 million of new commitments, and we have pending commitments of an additional $382.3 million in signed nonbinding term sheets. Our new deal pipeline currently exceeds $1 billion of potential investments, and we expect this number to increase and strengthen in terms of quality if the equity capital markets remain volatile. While the recent equity market volatility for certain growth stage companies may negatively impact net asset value short term, we expect it to be a long-term net benefit to our business in terms of increased investment opportunities.

Consistent with our historical approach to underwriting credit and our internally managed structure that allows us to focus on total shareholder return versus growth at all costs, we will remain patient and disciplined on new originations, irrespective of market conditions. During Q4, we continued to see strength in terms of portfolio company exits and liquidity events. For 2021, we had 16 M&A events, 16 companies that completed their public offerings through either traditional IPOs or SPAC mergers and eight additional companies that are in registration or have agreed to stack transactions for a total of 40 exit and liquidity events, breaking our previous annual record of 22. This, combined with continued very strong performance across our broader portfolio, again, drove high levels of early payoffs.

Early loan repayments were nearly $426 million, above the top end of our guidance of $300 million and a significant increase from $319 million in Q3. For the year, we had a record $1.1 billion of early payoffs, surpassing 2020's level of $709 million. This increase is solid evidence of the strength of our portfolio and the ability to pick the top companies to partner with. For Q1 2022, we expect prepayments to slow and be between $150 million and $250 million, although this could change materially as we progress in the quarter.

The lower levels of early payoffs that we are projecting will reduce our short-term net investment income because of lower fee income but should position us to deliver greater net portfolio growth and enhance the longer-term earnings power of the business, assuming that originations remain strong. Even with the record levels of early prepayments in 2021, our record originations activity put us in position to deliver net debt investment portfolio growth of over $120 million, while at the same time, allowing us to assign to and/or fund directly over $225 million of investments out of the new external private funds that we now manage through our wholly owned advisor subsidiary. Our private funds business has allowed us to increase the size of our addressable market, scale further with our companies as they grow and continues to position us well to take advantage of market opportunities when they arise. Since launching our first private fund in Q1 2021, we have secured over $500 million of equity and debt commitments to date.

This provides us with tremendous optionality and flexibility in terms of new business generation going forward. The majority of our prepayments in 2021 were directly attributable to M&A events and enhanced liquidity for many of our borrowers as a result of the strong capital markets for the best-performing companies. This trend continued in Q4, where over $225 million of our early prepayments came as a direct result of M&A transactions or equity capital markets events. The velocity of capital in our ecosystem makes achieving and sustaining scale difficult, but we have proven the unique ability to do this over the last 17-plus years, which is a clear differentiator of our business and our platform.

In Q4, we generated total investment income of $72.5 million and net investment income of $40.4 million or $0.35 per share. Our portfolio generated a GAAP effective yield of 13% in Q4 and a core yield of 11.2%, which was consistent with our guidance for the quarter. With net regulatory leverage at a very conservative 73.9% and continued robust liquidity across our platform, we remain very well-positioned. Credit quality on the debt investment portfolio remained solid in Q4 with a weighted average internal credit rating of 2.10, as compared to 1.92 in Q3.

Overall, our grade one and two credits decreased slightly to 73.2% in Q4 versus 79.4% in Q3. Grade three credits increased slightly to 26.3% in Q4 versus 20.2% in Q3. Our rated four and five credits made up 0.5% of the entire debt portfolio fair value. In Q4, the number of loans on nonaccrual remains the same with three debt investments with a cumulative investment cost and fair value of approximately $24 million and $10 million, respectively or 1% and 0.4% as a percentage of the company's total investment portfolio at cost and value, respectively.

During Q4, Hercules had net realized gains of $6.3 million, comprised of gross realized gains of $9 million offset by $2.7 million of gross realized losses due to the loss on debt extinguishment. For 2021, Hercules had net realized gains of $20.9 million, comprised of gross realized gains of $25.3 million offset by $4.4 million of gross realized losses due to the loss on debt extinguishment. We ended Q4 with strong liquidity of $628 million, which provides us with substantial coverage of our available unfunded commitments of $287 million and the ability to fund our ongoing anticipated business activity. Seth will discuss our most recent institutional bond raise and the repayment of the convertible bond and redemption of our 2022 notes and how it will further drive down our cost of debt capital.

We have made substantial progress in terms of lowering our cost of debt capital and pushing out our debt maturity wall over the course of the last several years, and these efforts are ongoing. The venture capital ecosystem continued its sprint to an all-time record closing 2021 with fundraising activity at $128 billion and investment activity at $330 billion compared to $87 million and $167 billion in 2020, respectively, according to data gathered by PitchBook and the National Venture Capital Association. To provide some reference, VC investment activity increased 98% year over year, similar to our own debt and equity commitments increasing 122% year over year. For the year 2021, inclusive of Q4, we have declared $1.66 of distributions to our shareholders, which is a 23% increase over the same period last year.

Given the positive outlook that we have on our business, in combination with our record undistributed earnings spillover of approximately $192.1 million or $1.65 per share, our board of directors have approved a new supplemental cash distribution program of $0.60 for the next 4 quarters, payable $0.15 per quarter beginning with Q4 2021, which was previously $0.07 per quarter. The undistributed earnings spillover continues to provide us with added flexibility with respect to our shareholder distributions going forward and the ability to continue to invest in our team and platform. Throughout the course of 2021, we added talent to all levels of our organization and made investments in our infrastructure and platform. In addition, as we previously announced, we made two promotions that added a chief operating officer and chief credit officer to the executive management team, as well as naming a new general counsel.

These investments and promotions are designed to best position us to source, service and support our growing and diversified investment platform. We accomplished a lot in 2021, and I am grateful to each of our talented employees who contributed to our success this past year. We set records for new fundings and commitments. We expanded our industry-leading platform with the launch of our private credit fund business.

We further strengthened our balance sheet and enhanced our product offering capabilities. These achievements contributed to us being able to increase our shareholder distributions by 23% year-over-year and have positioned us incredibly well heading into 2022. We are thankful to the many companies, management teams and investors that continue to make Hercules their partner of choice. With our expanded platform, diversified business model and scale, we look forward to being able to support these companies over the years to come.

I will now turn the call over to Seth.

Seth Meyer -- Chief Financial Officer

Thank you, Scott, and good afternoon, ladies and gentlemen. With another record quarter for Hercules, we capped off a record-breaking 2021, where we were able to successfully deliver on several of the key strategic objectives that we had set out to achieve. In addition to record investment activity, we were able to strengthen our team, platform and infrastructure, expand and enhance our balance sheet and lower our cost of capital. Since 2020, our weighted average cost of debt has reduced from 5.2% to 4.5% in the most recent quarter.

We were able to do this by, among other things, repaying more expensive legacy instruments through the issuance of $325 million of institutional unsecured notes at a very attractive fixed coupon of 2.65%. In addition, we opened a new credit facility with SMBC, providing $100 million of additional liquidity at a reduced cost and flexibility aligned with our business needs. We ended the year with very strong liquidity and modest leverage, positioning ourselves well to opportunistically take advantage of the market in 2022. Our efforts to continue to strengthen our balance sheet and lower our cost of capital are ongoing, and I will speak to what we have already done in this regard in Q1 of 2022 shortly.

As usual, I'll focus on the following areas: first, the income statement performance and highlights; second, the NAV unrealized and realized activity; third, the leverage and liquidity; and then finally, fourth, the outlook. Turning our attention to the income statement performance and highlights. Net investment income was $40.4 million or $0.35 per share in Q4, an increase compared to the prior quarter, again, attributable to the growth in the net interest margin. Total investment income was $72.5 million, also an increase compared to the prior quarter.

Similar to prior quarters, the increase in fee income was at a lower rate than the increase in payoffs, largely due to the vintage and size of the onetime and unamortized fees associated with the loans that paid off. Our effective and core yields in the fourth quarter were 13% and 11.2%, respectively, compared to 12.7% and 11.4% in the third quarter. The slight decline in the core yield was due to a modest decrease in coupon interest. Turning to expenses.

Our gross operating expenses for the quarter increased slightly to $33.7 million compared to $33.4 million in the prior quarter. Net of cost recharged to the RIA, our operating expenses were $32.1 million, in line with the prior quarter. Interest expense and fees decreased again to $14.1 million from $14.7 million in the prior quarter. The acceleration of unamortized debt issuance cost on repayment of the securitizations in October is shown separately as a realized loss in the current quarter.

SG&A expenses increased to $19.6 million from $18.7 million in the prior quarter, higher than my guidance. The increase compared to the guidance and the previous quarter was driven by higher compensation expenses, primarily related to the record funding activity in the quarter. Net of cost recharged to the RIA, the SG&A expenses were $18 million. Our weighted average cost of debt was 4.5%, which represents a 40 basis point decrease compared to the prior quarter of 4.9%.

The reduction is due to the refinancing of $289 million of securitizations, carrying an average interest expense of more than 4.6% and higher utilization of the lower-cost SBA loans. Our ROAE or NII over average equity was 12.3% for the fourth quarter, and our ROAA or NII over average total assets was 6.1%. Switching to NAV and unrealized and realized activity. During the quarter, our NAV decreased $0.32 per share to $11.22 per share.

This represents an NAV per share decrease of 2.8% quarter-over-quarter. The main driver for the decrease was the $42.9 million of change in unrealized depreciation, offset by $6.3 million of realized gains, resulting in a $36.6 million decrease to the NAV. The $36.6 million decrease was primarily related to the mark-to-market movement on our publicly traded equity positions. The net realized gain of $6.3 million comprised of $9 million of gains from the disposal of equity and warrant positions offset by $2.7 million of realized loss relating to debt extinguishments.

For leverage and liquidity, our GAAP and regulatory leverage was 95.6% and 84.1%, respectively, which decreased compared to the prior quarter due to the one-month overlap of the new debt issuance in September and the repayment of the two securitizations in October. Netting out leverage with cash on the balance sheet, our net GAAP and regulatory leverage was 85.4% and 73.9%, respectively, putting us in a very strong position heading into the new year. We continue to utilize our third SBA license, drawing down an additional $86 million of debentures and an attractive annual interest cost of approximately 2%. As of year-end, we have access to an additional $24.5 million of SBA debentures for qualifying investments.

We ended the quarter with strong liquidity of $628 million. As a reminder, this excludes the capital raised by the funds managed by our wholly owned RIA subsidiary. Subsequent to year-end, as previously announced, in January, we issued $350 million of institutional unsecured notes at an attractive fixed coupon of 3.375%. The proceeds were utilized in February to redeem $230 million of 4.375% convertible notes upon maturity and $150 million of 4.625% October '22 notes with a small premium for early redemption.

These steps, combined with those taken in the fall of 2021, represent a refinancing of over 50% of our leverage outstanding, push our next material long-term maturity date out to 2024 and will continue to drive down our overall cost of debt capital further. Finally, on the outlook points. For the first quarter, our core yield guidance is 11% to 11.5%, which is in line with our experience during the second half of 2021. As a reminder, 94% of our portfolio -- our debt portfolio is floating with a four.

So the anticipated interest rate hikes in 2022 will ultimately benefit our core year yield going forward. Although very difficult to predict, as communicated by Scott, we expect $150 million to $250 million in prepayment activity in the first quarter. Consistent with 2021, we expect first-quarter prepayments to result in a lower acceleration fee recognition rate of 2.5% to 3% due to the average vintage of the prepayments. We expect our first quarter interest expense to remain stable compared to the prior quarter.

Although we have continued to lower our long-term cost of debt, the refinancing completed in the first quarter results in some duplication of costs related to the time of execution of borrowing and repayment of the two instruments. For the first quarter, we expect gross SG&A expenses of $19 million to $20 million, with the midpoint being consistent with the fourth quarter. As a reminder, the first quarter always has higher payroll taxes. In the first quarter, we expect a similar level of RIA allocation to what we saw in the second and third quarter of 2021, so $1.2 million to $1.3 million as the fourth quarter was elevated due to higher originations and allocated business.

Due to the steps taken year-to-date to lower our cost of capital, I want to speak to two points relevant for our first quarter outlook. First, regarding the refinancing of the $150 million of October '22 notes, we expect approximately $3.6 million or $0.03 per share of loss on debt extinguishment to be reflected as a realized loss. This is for the premium on early redemption and acceleration of unamortized debt issuance costs. Second, regarding the settlement of the $230 million of convertible notes.

As a reminder, we elected to settle the principal in cash and the option value in shares. The option settlement resulted in the issuance of just under one million shares, which will impact the Q1 net asset value and have a short-term dilutive impact on net investment income. This, combined with the lower expected prepayments in Q1, fewer calendar days in the quarter and, as I mentioned before, higher payroll taxes will likely lead to lower net investment income per share in Q1 as compared to Q4. We are closing out an exceptional year and are looking forward to another strong year ahead.

I will now turn the call over to the operator to begin the Q&A part of our call. Carmen, over to you.

Questions & Answers:

Operator

Thank you. [Operator instructions] Your first question comes from Crispin Love with Piper Sander. Your question please.

Crispin Love -- Piper Sandler -- Analyst

Thanks. Good afternoon. First on the migration of Grade one to Grade two and three credits. Can you give a little bit more detail on what drove that, if there was any specific subsectors where you saw anything where any degradation there? And then other than what drove that, just kind of what your near-term expectations are for credit quality and just the health of the companies in your portfolio?

Scott Bluestein -- Chief Executive Officer and Chief Investment Officer

Sure. Thanks, Crispin. The changes in terms of the credit ratings were not material in any of the categories. The biggest driver of the decline in rated one credits was actually from payoffs.

We had several larger rated one credits that were -- that the loans actually paid off in Q4 as a result of M&A transactions. So as those Grade one credits rolled off, the percentage of grade one credits in the books just sort of declined quarter over quarter. There was really no -- nothing material to speak to outside of the fact that just three large Grade one credits paid off as a result of M&A transactions in the quarter. In terms of our credit outlook, I would tell you that we are continuing to see strength across the portfolio.

There was a slight move downward in the weighted average credit rating across the portfolio in Q4 but nothing material. If you look at it on sort of a year-over-year basis, our weighted average credit rating at the end of Q4 was 2.10 if you look at our weighted average credit rating at the end of Q4 and the year ago period, it was 2.16. So very stable throughout the year, and we're really not seeing any signs that tell us that we're not going to continue to see a pretty stable credit environment for our portfolio going forward.

Crispin Love -- Piper Sandler -- Analyst

Thanks. So that's helpful. And then just. On the environment as a whole, like how are you viewing the current environment, especially with the volatility that we've been seeing in public market valuations? And then from your seat as well, how have public valuations fared relative to private valuations? And then just how do you expect the volatility to impact equity raising, IPO exits and then just pet your debt level?

Scott Bluestein -- Chief Executive Officer and Chief Investment Officer

Sure. So there's a lot there. And what I would tell you is our view of the current environment is that it's actually quite attractive for us, which is why I think you heard a lot of optimism in terms of our prepared remarks and why you're seeing the activity that you're already seeing in terms of our Q1 closed and Q1 pending numbers. Volatility in the equity markets, whether it's public equity or in the private markets from a private capital raise perspective, will negatively impact net asset value short term, right? Our book is mark-to-market on a quarterly basis.

If the stock prices for our public equity and warrants go down, you'll see some NAV decline quarter-over-quarter, and that's what you saw in Q4 of this year. From an NII perspective, we view it as a long-term net positive because we expect to see and we are seeing more opportunities for us to make attractive investments. We are seeing better quality companies come to us looking for debt solutions. And I think this is where having an experienced team that's been doing this for 17-plus years is a key differentiator of our business.

There are a lot of companies right now that are looking to the debt markets because they don't view the equity markets as attractive, and then there are a lot of companies that are looking to the debt markets right now because they just simply can't raise equity. And I think having a team that can distinguish and differentiate between those two scenarios is critical. I think we have a proven track record of being able to identify in volatile markets. Those companies that can raise equity just want to defer it because the valuations aren't there versus going after and chasing the companies that just can't raise equity.

And so we're very optimistic about the current environment. We're obviously cognizant of the increased volatility, and it's something that we're watching pretty closely. But we are absolutely of the view that, that's a net positive for our ability to originate attractive quality deals on a short- and medium-term basis here.

Crispin Love -- Piper Sandler -- Analyst

All right. Thank you Scott. Thank you for taking my question.

Operator

Thank you. Our next question comes from Kevin Fultz with JMP Securities. Your question, please.

Kevin Fultz -- JMP Securities -- Analyst

Hi. Good afternoon. Thank you for taking my question. In your prepared remarks, you noted that prepayment activity in the current quarter is coming down a bit.

Can you talk about your expectations for Hercules investment portfolio growth over the next few quarters?

Scott Bluestein -- Chief Executive Officer and Chief Investment Officer

Sure. So we don't provide portfolio growth guidance, and we don't provide NII guidance on a go-forward basis. What I can tell you is that we do expect prepayments to slow. If you look at the last 2 quarters of 2021, in Q4, we had $425 million of prepayments.

In Q3, we had $319 million, and then our guidance for Q1 is $150 million to $250 million. So we do expect on a short-term basis prepayments to decline, which given the strength of our originations activity should lead to greater net portfolio growth short term, but we don't have a specific number that we're prepared to speak to in terms of guidance. And then longer-term outlook, it's still difficult to sort of provide any perspective on prepayments longer term. If you were to ask us today, our expectation would be that we expect prepayments to normalize and revert back to what we traditionally saw going back first half of '21 into 2020.

Kevin Fultz -- JMP Securities -- Analyst

OK That's helpful. And then just a follow-up question relating to interest rate sensitivity. Could you provide the weighted average LIBOR floor for floating rate investments?

Seth Meyer -- Chief Financial Officer

Say it again, Kevin, you said the weighted average floor?

Kevin Fultz -- JMP Securities -- Analyst

The weighted average LIBOR floor for floating rate investments.

Seth Meyer -- Chief Financial Officer

So our floor is 1% on our LIBOR loans. So it's not weighted average, it just is 1%.

Kevin Fultz -- JMP Securities -- Analyst

Got it. OK. That's helpful. And that's it for me, and congratulations on a strong quarter.

Seth Meyer -- Chief Financial Officer

Thank you.

Scott Bluestein -- Chief Executive Officer and Chief Investment Officer

Thanks Kevin.

Operator

Thank you. Our next question comes from Finian O'Shea with Wells Fargo Securities. Your question please.

Fin O'Shea

Hi everyone, good afternoon. Scott, during the COVID there last year or two years ago, you would give us certain metrics on the liquidity runway for your portfolio companies. Not expecting you to have that in front of you still. But if you do, can you touch on it or otherwise tell us how that has trended into today's market?

Scott Bluestein -- Chief Executive Officer and Chief Investment Officer

Sure. Thanks, Fin. So we stopped providing that about a year ago, so we do not have that at the top of our tongue here for the call. What I would tell you is from a high-level perspective, we really haven't seen any material changes throughout the course of 2021.

Capital raising for our portfolio continue to be incredibly strong and robust in Q4. We had several companies, some that were public, some that were private, raise large rounds of financing in Q4. On a quarter-to-date basis, we have continued to see companies be able to raise equity capital. So from an RML perspective or from a key metrics perspective, really wouldn't anticipate there being any material change from some of the items that we discussed historically.

So we don't have that information updated as of Q4.

Fin O'Shea

Sure. Understood. That's helpful. And just a follow-up for raising for Hercules.

I think you said the fund is $500 million or so now. Can you remind us how you think about capital raising between the BDC and the fund you manage? Is there some relative return or opportunity analysis? Or have you been just focused on getting that scaled? And where are you in that journey?

Scott Bluestein -- Chief Executive Officer and Chief Investment Officer

Sure. So the focus for us is on both platforms: the public BDC and the private fund business. I would point out, again, the model that we've been able to utilize to set this up is unique in the industry. All of the benefit of our private credit fund business, whether it is additional net investment income or net asset value appreciation as a result of the valuation of that RIA business, accretes to the benefit of our public company shareholders.

So when we think about public BDC versus private credit funds, we're largely agnostic. Because the reality is the better performance that we get out of the private fund business, the better it is for our public company shareholders. The private fund business over the course of the last 12 months has really accomplished exactly what we expected it to accomplish. It's allowed us to pursue larger, more later-stage transactions.

It has significantly increased the addressable market that we're able to pursue, and you can see that by virtue of what we accomplished in 2021 with $2.65 billion of commitments, $1.6 billion of fundings. The private fund business has also allowed us to be really more competitive with respect to some larger public transactions and some international transactions, and it's also provided a significant benefit on a short-term basis to our shareholders by virtue of the fact that we're able to spread the costs of our platform across, not just the public BDC, but now also through the private credit fund business as well.

Fin O'Shea

That's helpful. Thank you so much. Congrats on the quarter.

Scott Bluestein -- Chief Executive Officer and Chief Investment Officer

Thanks Fin.

Operator

Thank you. Our next question comes from Christopher Nolan with Ladenburg Thalmann. Your question please.

Chris Nolan -- Ladenburg Thalmann -- Analyst

Seth, when assuming the Fed raises rates, what's the timing difference do you expect to hit for the left and right side of the balance sheet?

Seth Meyer -- Chief Financial Officer

So it's -- on the left and right-hand side of the balance sheet, on the left side, it's pretty instantaneous. So it's floating with the floor, assuming that the interest rate is not well will flow the floor, which they would not be. Then it will automatically generate additional income for us on the left-hand side. On the right-hand side, the floating instruments that we have are our credit facilities.

As you probably saw, Chris, there was minimal borrowing on the $500 million in capacity that we have on the credit facilities. About $29 million or $30 million is my recollection. So it would depend on how drawn those facilities are as to what the impact would be, but the majority of our $1.25 billion in debt is a fixed rate.

Chris Nolan -- Ladenburg Thalmann -- Analyst

Great. As a follow-up, as you -- as the market is pricing in a bunch of Fed rate hikes, how do you anticipate your prepayment volumes will perform? Will they go up, go down? What are you guys thinking along those lines?

Seth Meyer -- Chief Financial Officer

Well, I think, as Scott expressed, and maybe Scott jump in, in a second, but express -- the market volatility in general and actions of the Fed by removing liquidity out of the market should be very beneficial for us, not only on originations, but moving us back to that new normal. Where that is exactly, we'll have to wait and see, but less than $1.1 billion certainly over 2022 as we saw in 2021. So I would expect that those actions will actually be beneficial for us to retain business and originate even better business.

Chris Nolan -- Ladenburg Thalmann -- Analyst

Great. Thank you.

Thank you. Our next question comes from Kenneth Lee with RBC Capital Markets. Your question please.

Ken Lee -- RBC Capital Markets --- Analyst

Hi. Thanks for taking my question. One on the follow-up on the liability side. You talked about lowering some funding costs over the past year.

Wondering if you could talk about any further expectations of further optimizations on your funding costs going forward? Thanks.

Seth Meyer -- Chief Financial Officer

Yes, absolutely, Ken. So as I mentioned, we've refinanced more than 50% of our fixed rate instruments, and we've really addressed everything that was within reach of a reasonable economic prepayment penalty, where we felt that it was advantageous for us, for our shareholders, to make any prepayment penalty with the given interest rate environment. So I would say that we will continue to strategically evaluate the present value of each of those instruments that we still have outstanding and determine whether there are additional instruments that come available, for instance, in the passage of time when make-whole premiums become more reasonable as they're constructed in the instruments or as interest rates move in the correct direction to beneficially cause us to decide that economically it makes sense to go out and refinance additional portions of that. But at the moment, we have no plans that we could communicate related to that.

It's just a statement that absolutely we'll do what economically makes sense for the shareholders.

Ken Lee -- RBC Capital Markets --- Analyst

Great. And just one follow-up if I may, and this is just a follow-up to some of the previous questions around the volatile equity markets. Wondering if you could just talk about what you saw historically in terms of the volatility around equity markets and potential implications for the debt investment valuations. Maybe just talk about what you're seeing around loan spreads currently.

Thanks.

Scott Bluestein -- Chief Executive Officer and Chief Investment Officer

Sure. So from a spread perspective, we're seeing a pretty stable environment. In Seth's prepared remarks, we gave core yield guidance for Q1 of 11% to 11.5%. That is consistent with our core yield guidance throughout the course of 2021.

We're really not expecting to see much change there with respect to core yield guidance. And so we really -- from a pure sort of correlation perspective, we're expecting a pretty benign environment as it relates to that question.

Ken Lee -- RBC Capital Markets --- Analyst

That's very helpful. Thanks again.

Operator

Thank you. Our next question comes from Ryan Lynch with KBW. Your question please.

Ryan Lynch -- KBW -- Analyst

Hi, good afternoon. First, I kind of wanted to touch on Scott. Some of your comments on kind of the outlook for credit quality in your portfolio, you said it looks like it's going to be pretty strong going forward. If I just think about the volatility that we've had in the equity markets and that putting pressure on private market high-growth valuations, it's going to be harder for -- I would think for some of your portfolio companies to raise additional rounds of capital at previous valuations potentially as there's just been a whole valuation reset in some of these private markets.

And so I would think that, that would potentially put some pressure on some of your borrowers. I'd love to hear just kind of your thoughts on that.

Scott Bluestein -- Chief Executive Officer and Chief Investment Officer

Sure. So valuation and valuations in general are really just one part of the analysis that we do when we're thinking about sort of credit, credit performance, credit rating and credit outlook. If you look historically at how we underwrite credits, we're typically underwriting these loans at a loan to value of 10% to 20%. Weighted average loan-to-value across our portfolio at the end of the year was roughly 13%, 14%.

So even with a significant or a material downtick in valuations, the loan to value across our portfolio continues to be incredibly attractive. Companies that are not raising equity capital because they can't are obviously going to be negatively impacted from a credit perspective. We would view those situations very differently than we would view a company that is simply deferring an equity round because it's not happy with the valuation. If the company is performing from a metric perspective from some of the other KPIs that we look to when determining credit, it really doesn't have a significant impact.

I would also point out, and we made this comment throughout the course of 2021, when you had those few periods where our weighted average credit rating dropped below two times, that was not a normal credit environment for us. If you look historically, going back 17 years, our weighted average credit rating has typically been in the 2.2 to 2.5 times range. And so for us, that is reflective of a very stable credit environment. We're still below that when you look at our weighted average credit rating at the end of Q4 at 2.10.

So while there could be some decline in that weighted average credit rating over the course of the next couple of quarters. We are not seeing any signs that would lead us to believe that it's going to revert outside of our historical credit performance metrics.

Ryan Lynch -- KBW -- Analyst

OK. Have you noticed any meaningful change in some of your borrowers' willingness to try to raise additional equity in these markets? Or are they also looking for different sources, as you mentioned, the opportunity set for you as they may pursue more debt options versus equity options?

Scott Bluestein -- Chief Executive Officer and Chief Investment Officer

It's a great question. We've really noticed it more from the perspective of potential new borrowers. There were several companies that we were having conversations with consistently throughout the course of the last year that kept sort of deferring that decision to go forward and raise debt capital because they were contemplating either a private equity round or raising equity capital in the public markets. We've seen a significant increase in the number of those companies coming back to us over the course of the last 60 days and now just with a very different tone and sort of context for the discussions.

Whereas last year, it was we like what you're able to offer, but we just think the equity markets are more attractive. Now a lot of those companies are coming to us and saying, "We're going to move forward and we're going to do a round of debt financing here," and wanting to talk to us, which is why we are incredibly optimistic about our originations activity over the short to medium term. So we've seen it more from a new borrower perspective than we've really seen it from a portfolio perspective. The companies in our portfolio that we're contemplating raising rounds of capital have largely done so over the course of the last 90 days.

Ryan Lynch -- KBW -- Analyst

OK. Understood. On a separate point, I'm trying to get a better understanding of how I should think about the expense reimbursements from the advisor because you kind of guided for it decreasing in Q1, closer to some previous quarters, Q2 and Q3 levels. I would have thought as the AUM under that advisor grows, which it has been in the last several quarters, I would have thought that, that expense allocation would have actually increased.

And so we would have seen kind of a lock step increase going forward, as we've seen in the last several quarters. So I was kind of surprised to see it -- the guidance expect a decrease in Q1. Can you talk about how is that expense reimbursement decided? Is it based actually on the NOI earnings and that's -- in those funds, which you talked about were kind of stronger in Q4 and may go lower in Q1 given lower prepayment fees? Any color around that would be very helpful.

Seth Meyer -- Chief Financial Officer

Yes. Ryan, your question is pretty logical. It makes sense. So let me explain the construction of it.

I gave that guidance because we did have an outsized record quarter in originations, new fundings, not only could the commitments, but the fundings as well. And we're certainly not projecting that we beat that again in the short term. So hopefully, we do. But the construction of it is really three categories of expenses.

One, the direct expenses related to originating and funding business that gets allocated or originated by the funds themselves, so that includes the originator bonuses that we've talked about in the past that are the variable part of our compensation. The second is, but a much smaller portion of it, related to AUM. So those support functions, finance, operations, legal, anybody that is working related to the continued operations of those funds. And that is largely connected to either time allocated or AUM if there's a pure math associated with that.

And then direct expenses, which is an even smaller portion of it, related to accounting services, legal services that the funds themselves need to procure and certainly any investment services. So it's those three categories, and the biggest category is that first one, and that is why we're guiding to a lower allocation because we're not guiding to a record quarter of funding.

Ryan Lynch -- KBW -- Analyst

Got you. That's a very helpful breakdown of how that expense allocation works. So I appreciate that, and I appreciate you taking my questions this afternoon.

Seth Meyer -- Chief Financial Officer

Thanks Ryan.

Operator

Thank you. [Operator instructions] We have a question from the line of Stacy Alexander with Compass Point. Your line is open.

Casey Alexander -- Compass Point -- Analyst

Stacy, I've been called worse than that before. So I have two questions. First of all, in the fourth quarter and also in the subsequent events, putting them together, the company looks like it sold about 2.1 million shares of common stock under the equity ATM program. I'm just curious what the thinking is in terms of selling your own stock as opposed to just raising those funds with a publicly traded equity portfolio that's a much larger size is equally as liquid, I'm just curious, why go the direction of selling your own stock as opposed to some of the publicly traded equity that you held? Even though maybe you're not top taking it, is still well ahead of much of its cost.

Scott Bluestein -- Chief Executive Officer and Chief Investment Officer

Sure. Thanks, Casey. Great question, and two specific things that I would say on that. So number one, if you think about what we did from a liability perspective over the course of the quarter, we paid off $380 million of debt between the prepayment or the payoff of the convertible note in February, as well as the October 2022 bond retirement, and we replaced that with a $350 million unsecured institutional public bonds.

So there was a small delta there between the $350 million that we raised and the $380 million that we paid off. The second part, which is the more important piece, is we are seeing tremendous strength right now from an originations perspective. You pointed out some of the subsequent disclosures. We also disclosed between our closed and pending commitment activity through February '18.

We're already at about $621 million of closed and pending transactions. And we're also projecting, per Seth's comments, prepayments to slow pretty considerably down to that $150 million to $250 million guidance. So some of that activity was really essentially in preparation for what we expect to be enhanced portfolio growth over the course of the next quarter or two, and those are really the two key drivers of that. I would also point out that through the course of Q4, we did continue to sell some of our public stock positions.

We had close to $10 million of net realized gains from dispositions of our public stock positions, and we would expect those efforts to continue to monetize some of those positions, obviously, subject to market conditions to continue.

Casey Alexander -- Compass Point -- Analyst

Great. Thank you for that. My other question is the shareholders are benefiting right now from the special distributions working down what is a large amount of spillover on a -- I think Seth said that at around $1.60 a share. What do you need to get that spillover down to where you're comfortable you're not going to feel the need to push out the special supplemental distributions any longer? Is it below $1 a share? Or what's the thinking on that?

Scott Bluestein -- Chief Executive Officer and Chief Investment Officer

Yes. I think you hit the nail right on the head there, Casey. There is no preset sort of target. But in an ideal situation, we would work that spillover down to about $1 per share.

Right now, it's at $1.65 per share. If you assume no activity in the course of 2022, which is obviously not a real expectation, but if you just sort of model it out, did nothing from a realized activity up or down in 2022. With the $0.60 supplemental distribution that we declared now, we would get that $1.65 down right roughly to about $1 per share at the end of 2022, assuming no other changes.

Casey Alexander -- Compass Point -- Analyst

Awesome. Thank you. That's very very helpful. I appreciate you taking the questions.

Thanks very much.

Scott Bluestein -- Chief Executive Officer and Chief Investment Officer
