Thank you, Michael, and thank you all for joining us today. Our strong finish in Q4 capped off a record year, where our key competitive advantages and our differentiated lending model were once again reflected in our results. We delivered strong new debt and equity commitments and total gross fundings, while continuing to deliver superior and consistent credit performance and operating results.
Our overall performance throughout 2019 put us in a strong position to declare record shareholder distributions for 2019. And more importantly, we continue to believe that we are well positioned at this particular juncture of the credit and economic cycle. The continued strength of our originations platform, robust liquidity and strong balance sheet delivered another year of outstanding growth, profitability and credit quality, with records on multiple fronts, including: total investment income of $267.9 million, up 29%; net investment income of $143.3 million, up 32%; new debt and equity commitments of $1.47 billion, up 22%; total gross fundings of $1.03 billion, up 7%; debt investment portfolio of $2.17 billion at cost, up 24%; total portfolio investments of $2.4 billion at cost, up 21%; total assets of $2.46 billion, up 24%; total declared shareholder distributions of $1.42 per share; and undistributed earnings spillover of $68 million or $0.67 per share based on weighted average shares outstanding.
In Q4, we originated new debt and equity commitments of $283.9 million, an increase of nearly 14% from the same period last year. Our strong performance in Q4 allowed us to achieve record new debt and equity commitments in 2019 of $1.47 billion. In addition, our current pipeline remains strong with approximately $1 billion in potential transactions.
In Q4, our investment-related activity continued to reflect our focus on 3 key themes: first, diversification, where our objectives are centered on building and maintaining a broadly diversified portfolio and avoiding concentrated or binary risk; second, delivering controlled growth without sacrificing our credit and underwriting standards and discipline; and third, positioning the portfolio best for where we believe we are in the credit cycle.
During the quarter, we were successful in each of these 3 areas of focus, and I am incredibly proud of the entire Hercules investment team and broader organization for our achievements in 2019. We have chosen to build and grow our business with an emphasis on diversification and risk management. During the fourth quarter, we funded 10 new and 11 existing portfolio companies. Consistent with what we saw throughout 2019, the majority of the 11 existing portfolio companies that we funded during Q4 were situations where our portfolio companies achieved specific performance milestones or growth targets that unlocked additional capital availability.
As our debt portfolio has continued to grow and our portfolio companies have continued to perform, we are seeing more opportunities to expand and enhance our funding relationships with existing borrowers, who chose Hercules Capital in part because of our unique ability to grow and scale with them as their funding needs increase. We ended the year with a total of 97 debt portfolio companies. The profile of the 10 new companies that we made debt commitments to was consistent with our focus on quality, diversification and differentiation. We saw strong performance from both our technology and life sciences teams with respect to new debt commitments to both new and existing companies.
Our total fundings in Q4 were split nearly evenly between technology and life sciences companies, as we continue to emphasize diversification across our investment portfolio. At the end of Q4, our top 5 and top 10 debt positions made up 17% and 29% of our total debt portfolio at cost, respectively. We funded $240.9 million in Q4 and a record $1.03 billion for the year, the first time in our history that we have managed to fund in excess of $1 billion in a year.
As noted in our earnings release, early payoffs remained at a higher level, but did not produce a commensurate level of accelerated fee income due to the vintage of some of the paydowns. Seth will provide more detail in his comments. In Q4, we had $161 million of early payoffs, which was up from $140 million in Q3.
Consistent with what we have seen in each of the last 3 years, in 2019 we had $527 million in early payoffs compared to $487 million in 2018 and $506 million in 2017. As we continue to emphasize prudent risk management and portfolio quality, approximately 50% of the Q4 payoffs were attributable to either M&A-related events or prudent credit management.
With the growth of our debt investment portfolio and an increase in the average size of our loans, we expect quarterly payoffs throughout 2020 to remain elevated and lumpy. Our focus will remain on sustainable long-term performance and total shareholder returns.
Net debt portfolio growth of $68.8 million in Q4 drove our debt investment portfolio to a record $2.17 billion at cost. We had record net debt investment growth for 2019 of $417.2 million, which exceeded the high end of our debt investment portfolio growth targets for 2019.
Credit quality on the debt investment portfolio improved slightly in Q4 with a weighted average internal credit rating of 2.15 as compared to 2.17 in Q3. Our rated 1 credits as a percentage of our overall investment portfolio increased to 18% in Q4 from 11.4% in Q3, largely driven by a handful of companies continuing to perform above our initial expectations. Our rated 2 credits as a percentage of our investment portfolio decreased to 55% in Q4 from 64% in Q3. And our rated 4 and rated 5 credits continue to make up less than 3.5% of our entire debt portfolio. Nonaccruals remained low with 3 debt investments on nonaccrual with a cumulative investment cost and fair value of approximately $9 million and $1 million, respectively, or 0.4% and 0% as a percentage of the company's total investment portfolio at cost and value, respectively.
During 2019, we had $16.5 million of net realized gains across our investment portfolio, largely driven by M&A activity and several public market dispositions. Our diverse and well-structured balance sheet is designed to provide a long-term focused and sustainable investment platform and give us the flexibility to drive growth when we feel prudent. We ended Q4 with over $235 million of liquidity, which was further strengthened by our $120 million private placement of unsecured bonds in early February, our Q1 quarter-to-date ATM issuances of $35 million as well as the $400 million expanded and enhanced credit facility that we announced earlier today. Seth will provide greater details in his remarks.
We have made substantial progress in Q1 towards our goals of reducing our cost of capital, strengthening our liquidity position and improving our balance sheet flexibility. We continue to see strong loan demand and transaction deal flow, driven partly by the continued strong pace of U.S. venture capital investment activities, which ended the year with more than $103 billion invested and over $46 billion raised, according to Dow Jones and PitchBook's Q4 Venture Monitor, respectively.
Assuming market conditions remain favorable, we are anticipating all exit activity to continue at a steady pace. In 2019, 882 exits represented over $256 billion in exit value according to Venture Monitor. Evidencing our team's ability to pick the right companies to partner with, in 2019 Hercules Capital had 12 companies complete their IPOs and 13 companies complete M&A events.
Although we are very early in 2020, and we expect election year market volatility as we approach November, we remain optimistic by what we believe lies ahead. Our focus in the first half of this year will be centered on 3 specific items. First, enhancing and strengthening our balance sheet and liquidity position, both of which we believe differentiate Hercules from others in the space and provide us with a unique ability to fund our companies across numerous value inflection points without the need for them to seek debt capital elsewhere. We have taken several steps to not only enhance our liquidity position, but also drive down our cost of capital, and these steps remain active and ongoing. Being long liquidity is something that we believe will position us well to be aggressive and opportunistic moving forward.
Second, remaining disciplined underwriters of credit, where we underwrite each deal based on its specific credit attributes and not on what others may be doing to gain market share or a portfolio of assets. The competitive landscape remains heated, and in certain instances, we would rather slow growth than chase deals, where we do not believe the underwriting is warranted from a credit perspective. We have recently been passing on a higher number of the opportunities we are evaluating, largely based on our credit screens. Using our scale and -- sorry, third, using our scale and platform more aggressively for the right opportunities and to expand our product set.
I would now like to spend a few minutes discussing our shareholder distributions. With our debt investment portfolio at $2.17 billion at cost, our NII per share in Q4 generated 119% coverage above our quarterly base distribution of $0.32 per share. In addition to our quarterly base distribution of $0.32 per share in Q4, we also declared a supplemental distribution of $0.08 per share. In the aggregate, this brings our total declared distributions to shareholders for 2019 to $1.42, representing an increase of nearly 13% compared to 2018. This also represents the fourth consecutive quarter where the company's strong performance has allowed us to deliver an increased distribution to our shareholders.
In addition to our quarterly income exceeding our base distribution, we are also fortunate to have been able to grow our undistributed spillover to an estimated $68 million or $0.67 per share based on weighted average shares outstanding, subject to final tax filings for 2019.
This provides us with tremendous flexibility with respect to our variable base dividend going forward and the ability to continue to invest in our team and platform as we discussed during 2019, while at the same time optimizing total shareholder return.
In closing, our performance in Q4 and the full year 2019 was impressive on many fronts, but would -- it would not have been possible without the tremendous work and effort demonstrated by each of our talented employees across this organization. In January of this year, we announced another record-breaking milestone when we crossed $10 billion in cumulative debt commitments since inception.
I would like to close by acknowledging and thanking the nearly 500 different companies and management teams that have been a part of the Hercules story since 2004, and their incredible VC and sponsor investors who have all contributed to our success by choosing to make Hercules Capital their preferred partner of choice.
Thank you very much, and I will now turn the call over to Seth.
