Most notably, our investment and portfolio management teams embarked upon a comprehensive portfolio rationalization strategy, which will increase the earnings in overall yield on our capital. We are currently in the process of divesting certain inherited investments, which include non-core assets and investments that have experienced recent credit events in our meaningfully low or no yielding. Specifically, we come through the portfolio and identified assets where rationalization and redeployment will lead to accretive higher yielding returns on equity.

The strategy also identified refinancing opportunities, which will take advantage of the current credit market in mine (ph) additional investable capital in our portfolio. When Neil discusses our financial and operational results, you will note that our portfolio rationalization strategy may have generated short-term pain, but it's important to realize that this is the quickest path toward long-term earnings growth. While these proactive activities impacted our fourth quarter results, we believe these impairments are now behind us, and our go-forward strategy is the best direction for Colony Credit Real Estate to level set, efficiently execute our business plan, quickly resolve the identified investments and redeploy capital into higher yielding assets, that will enhance core earnings in 2019.

Before turning the call over to Neil, I'd like to provide a brief update on the top priorities that we articulated earlier in the year and the progress we have made on them during 2018. First, I'am very pleased with our success in deploying liquidity into targeted asset classes to grow and further diversify our investment portfolio. For the full year we allocated approximately $2.2 billion of capital for investment. We remain confident in our ability to continue to source transactions with an investment level return on equity in the low double-digit, which is consistent with the yields, we are achieving across our recent investment.

Our US origination pipeline is robust. As I've noted before, we continue to see compelling opportunities in Europe, where we believe there is less competitive pressure and where the current cycle appears to be several years behind the US. We will continue to benefit from the global infrastructure and best-in-class deal sourcing capabilities of Colony Capital as we evaluate new investment opportunities in 2019. By executing our portfolio rationalization strategy, and achieving our anticipated redeployment pace with new investments, we expect to generate core earnings run rate that fully covers our dividend by the year end 2019.

Additionally, we made good progress on the asset management front of our portfolio, I am pleased with the enhanced asset mix and ongoing geographic diversification. As I alluded to earlier, our near-term focus is the rotate out of identified lower yielding and non-core or credit impaired legacy assets, including several resolutions anticipated coming in the coming months. We expect the redeployment of capital into our higher yielding pipeline will have a meaningful impact to our go-forward core earnings.

Finally, we remain focused on increasing our return on equity by moderately increasing leverage. To this end, during the year, our debt to assets increased positively from 33% at the end of the first quarter to 46% at year-end. We remain on pace to achieve our targeted debt to asset of 50% to 55% during 2019, which still remains lower than our peer group. As we successfully execute on our strategic initiatives, we are confident in our ability to continue narrowing the trading discount the current book value and accretively grow the Company.

And now I'll turn the call over to Neale Redington for a more detailed explanation of our fourth quarter and year-end operational and financial result.

Neale W. Redington -- Chief Financial Officer

Thank you, Kevin, and good afternoon, everyone. As we discuss our fourth quarter financial results, I want to draw your attention to our supplemental Financial Report, which is available on our website. We believe this supplement will help investors and research analysts better understand our Company given the additional data it provides on each of our business segments. For the fourth quarter CLNC reported a GAAP net loss of $127.1 million or $1 per share and negative core earnings of $37.3 million dollars or $0.29 per share. Fourth quarter net income and core earnings included one, $69.7 million of realized losses from mark-to-market adjustments and tax expenses on our real estate private equity investment, and two, $10.2 million of realized losses from the sale of property and resolutions of loans.

Excluding these combined losses totaling approximately $80 million, forth quarter core earnings of $42.6 million or $0.33 per the diluted share. For the fiscal year 2018, we reported a GAAP net loss of $168.5 million or $1.41 per diluted share, and core earnings of $86.1 million or $0.70 per diluted share. Excluding realized net losses, 2018 core earnings was $175.8 million or $1.42 per share. Subsequent to the end of the quarter, our Board reapproved our initial $300 million stock repurchase program through March 2020. We believe the current share price is not indicative of CLNC's long term intrinsic value. We will continue to evaluate repurchasing shares as part of our overall capital allocation strategy. Including whether return on equity is at least consistent with our new investment pipeline.

Turning to our liquidity, the Company currently has access to $278 million between cash on hand and availability under our corporate revolving credit facility. We successfully upsized our corporate revolving credit facility from $400 million to $560 million, providing us with additional capacity for new investments. In addition, during the quarter, we successfully closed on a new $300 million master repurchase facility, which brings our total master repurchase facility capacity to $2.1 billion across six banking relationships.

I would now like to take a moment to discuss the impairments taken during the fourth quarter 2018. First, as Kevin mentioned as part of our overall portfolio rationalization strategy, we are accelerating the sale of our real estate private equity secondary interests. As a result of recent price discovery from this ongoing process, during the fourth quarter, we recorded a mark-to-market adjustment of $35 million as well as a $35 million write-off of the related deferred tax asset, both of which impacted our reported core earnings. We still aim to utilize this deferred tax asset to offset potential future capital gains on our investment portfolio.

Second, we reported $77 million of provisions for loan losses during the quarter related to four separate borrowers. I'd like to remind everyone as noted in our public disclosure, the reported core earnings excludes the impact of impairment of real estate and provision for loan losses, until a realization event occurs. Therefore reported fourth quarter core earnings excludes these losses taken to GAAP net income this quarter. So some specifics on the loan loss provisions. As Kevin mentioned earlier Colony Credit is taking proactive steps to rotate out of certain legacy underperforming and our non-core investments. In our call last quarter we mentioned that we were working through the restructuring of four loans secured by a New York City hotel, which remain on non-accrual status and impacting our quarterly core earnings by approximately $0.04 per share.

As part of our ongoing resolution efforts during the fourth quarter, the borrower entered into a listing agreement with the real estate brokerage firm. And as a result, we believe the sale of the underlying collateral, repayment of the four loans is the most likely outcome. As such, during the fourth quarter, we recorded an additional provision for loan loss on these four related New York hospitality loans to reflect the estimated proceeds to be received from the borrower following the sale. As New York City hotel room additions are being absorbed, we continue to be optimistic on the New York City lodging market recovery and the ability to exit this recent credit impaired asset.

Next in January 2019, we completed foreclosure on a portfolio of senior and mezzanine loans collateralized by 28 properties to a single borrower. During the fourth quarter, we recorded an impairment to reflect the estimated fair value of collateral, which included a provision for loan loss associated with protective advances paid by us from the borrowers' behalf during 2018. We are moving forward on these assets with a robust asset management plan to improve operating performance and have engaged new property managers working under the diligent oversight of our portfolio management team. We also expect to thoughtfully finance and/or dispose of certain assets within the portfolio in order to maximize value and go forward with the earnings.

Finally during the fourth quarter, two separate borrowers on three of our regional (inaudible) loans notified us of the potential loss of anchor tenants. Following this notification, we concluded that the foreclosure or sale of the underlying collateral and repayment of each of these loans is the most likely outcome. As such, we recorded a provision for loan loss for these loans. While the impairments and their impact on our operating results for this quarter were meaningful, we believe they are comprehensive and complete and that we are now well positioned to move forward with our business plan.

Turning to deployment, our fourth quarter was once again a productive quarter. Specifically, we allocated and initially funded $561 million, and $531 million of capital during the fourth quarter, including five senior loans totaling $486 million, including a $163 million investment in Dublin and two mezzanine loans for $75 million. Totally expected return on equity for these fourth quarter investments is approximately 14%. In addition, in the first quarter to date, we've already deployed an additional $199 million of capital, the full benefits of which will be realized in our core earnings in the coming quarters. We expect that this recent deployment of approximately $730 million, coupled with the redeployment of capital from the portfolio rationalization strategy that Kevin previously discussed will allow us to achieve our projected run rate dividend coverage during 2019.

For the fiscal year 2018, we successfully allocated approximately $2.2 billion in capital and funded $2 billion across 38 individual investments. Our average transaction size exceeded $50 million with an expected weighted average return on equity of 12%. The mix of these investments is approximately 58% senior loans, 28% net lease, 6% mezzanine loans, 5% preferred equity and 3% CMBS. Approximately 74% of these investments are in the US and 26% in Europe. The property type mix is approximately 40% office, 23% hospitality, 13% industrial, 11% multi-family and 13% mixed use. We increased our office and industrial exposure from 41% of our portfolio at the end of the first quarter to 53% at year-end. While at the same time, we reduced our exposure to hospitality and retail assets from 39% to 29%. Taken together, this exemplifies the breadth and execution capabilities of Colony's origination platform.

Looking at our in-place investment portfolio, our loan book continues to be the largest segment within our portfolio with a carrying value of $2.8 billion at quarter end. Over 85% of our senior loan portfolio and approximately 65% of our total loan portfolio is floating rate and thus we see accretive returns tied to the increases in LIBOR. With an average loan size of $36 million, the portfolio remains well diversified across collateral type and geography. Our second largest segment remains our triple-net lease portfolio with an undepreciated carrying value of $1.3 billion as of December 31, 2018. This portfolio consists primarily of industrial and office properties. With the high single-digits, weighted average return on equity and a weighted average lease term is 9.3 years, we view the net lease segment as a core business of CLNC providing long duration and stable cash flows with the potential for capital appreciation.

Moving to CRE debt securities, our portfolio had a carrying value of $371 million at quarter end and is predominantly investment grade rated. In addition to generating attractive yields and poised for growth, our CRE debt securities portfolio also provides CLNC with additional liquidity options within our investment portfolio and access to efficient borrowing.

Turning to our other real estate segment, which predominantly consists of cash flowing operating real estate, we brought our exposure down from 24% to 16%. This segment has an un-depreciated carrying value of $715 million as of quarter end. This decline by over $160 million since the third quarter, as a result of the sale of our largest non-core office portfolio during the fourth quarter. In addition, non-core holdings and real estate private equity funds had a total carrying value of $161 million at quarter end, net to the $35 million mark-to-market adjustment recognized during the quarter. Even our passive secondary interest in these funds and the volatility and timing of cash flows, we are now exploring sales and other strategic alternatives for these interests.

Moving onto our balance sheet, our total at-share assets stand at approximately $5.5 billion at year-end 2018. Our debt to assets ratio increased to 46% at the end of the quarter, but still remains lower than our peer group and our expected long-term target of 50% to 55%. As mentioned earlier, our current liquidity stands at approximately $278 million between cash on hand and availability under our revolving credit facility. Overall, we are optimistic as we look toward 2019. We've accomplished a lot during 2018 and we look forward to updating you on our progress on future calls, as we continue to monetize certain lower yielding and non-core legacy assets and deploy additional liquidity into high yielding targeted investments. Our portfolio rationalization and resolution strategy is well defined and our pipeline and new investment execution should follow the successes of our 2018 investment activity.

I would like to thank you for your time today and will now ask the operator to please open the line for questions.

Questions and Answers:

Operator

Thank you. We will now be conducting a question-and-answer session. (Operator Instructions) Our first question comes from the line of Stephen Laws with Raymond James. Please proceed with your question.

Stephen Laws -- Raymond James -- Analyst

Hi, good afternoon. Kevin, I guess maybe start with the real estate private equity interests. I guess there is a small mark in Q3 and then obviously took a bigger impairment this quarter. Can you talk about the process of selling that -- those assets and I think if I remember correctly when the initial investments were made, they are fairly complex. But can you talk about that the interest you made, you are possibly seeing and if you are unable to sell that at a price, you find attractive kind of what's the game plan from there? How should we think about running off and potential for additional writedowns, if it's not sold?

Kevin P. Traenkle -- Chief Executive Officer

Yes. Steven, and thanks for joining us and thanks for the question. Yes, for sure, I mean, yes, the real estate private equity interest as you may know, they don't fit well into a public company. Their earnings are a little bit lumpy, they hard to predict. So yes, we thought it was in the best interest just to kind of clean up some of the noise around the quarter-to-quarter, kind of mark-to-market that we're seeing is just to sell the portfolio and in fact it is for sale right now. We have a lot of interest. There is a number of parties that have been in the data room. And yes, we think it's going to trade at a number that it will be acceptable to us and I think is going to be able to kind of repatriate all the (ph) capital that we'll be able to redeploy into a much higher yielding assets. And we'll put this behind us and will be much better off for (ph) it.

Stephen Laws -- Raymond James -- Analyst

I appreciate the color there. And I guess, bigger picture on the whole portfolio. Q3, we had a New York hospitality and then some operating real estate took an impairment and then couple of issues in Q4. What kind of confidence do you guys have after reviewing the portfolio for the last three or -- really six months? The things are marked correctly, especially with the new accelerated plan to address the non-core assets. How do we think about the risk for additional writedowns from here on the existing portfolio?

Kevin P. Traenkle -- Chief Executive Officer

Yes, So the risks are very low. We've gone through the portfolio pretty extensively kind of asset-by-asset, loan-by-loan. Our focus has been on a number of lower yielding assets that we have on the books. And we kind of just looked at the opportunity that we have to kind of increase the yield that those assets versus redeploying the capital we can get, if we sold them and came to the conclusion that it's better just to sell those and kind of redeploy that capital into our pipeline, which is very robust. So we took a big long hard look on everything in the portfolio and everything that we have. We are generally happy with the yield that we're getting, these -- handful of assets where we realize these impairments. We did so and we thought it was in the best interest for a long-term earnings and growth potential for the firm. The assets that we're going to put up for sale, we're confident that we'll be able to get very attractive prices, likely clear these trades in the coming months here, and kind of really focus on our pipeline going forward.

Stephen Laws -- Raymond James -- Analyst

Great. That's a good segue. My next question really think more about the growth, especially getting things to ramp. I believe in your prepared remarks, you said you expected core earnings to cover the dividend, I believe by year-end. Please correct me on that, if I'm wrong. But when you look at your options for new investments, looks like senior loans have been active. Is that really where you see the most growth taking place this year, when you kind of look at the landscape today? How do you see the mix of assets with capital being deployed this year, as you grow the portfolio?

Kevin P. Traenkle -- Chief Executive Officer

Yes. So within the credit space and where we kind of classify ourselves as the credit REIT. So we do invest in little bit more up and down the capital stack, which is a good thing, because we're always kind of picking and choosing where we're finding the best risk adjusted yield. We have been seeing a lot of very attractive loan originations, therefore we've been executing those at a pretty good pace. If you look at our pipeline going forward, I think that the majority of our investments in our pipeline are also whole loan origination. So we like the risk-adjusted yield that we're seeing in that space. It will continue to look at a little bit more opportunistic from triple net lease transactions, when they come up in the right space at the right yields, with the right credits. Mezzanine investments ROE is something that we're looking at as well. But I'd say, a whole loan originations are probably the majority of what's in our pipeline going forward.

Neale W. Redington -- Chief Financial Officer

And Stephen, just to answer your question specific to dividend coverage and core earnings. Yes, we did say that we intend to pay a dividend coverage by the end of 2019. And we have a good pathway to get there through these deployments that Kevin just described.

Stephen Laws -- Raymond James -- Analyst

Great. Appreciate you're confirming that. Last question, I asked this last quarter as well, but, you reauthorized or I guess extended the share repurchase authorization. Can you maybe talk about how management thinks about the opportunity to buy back stock at the valuation levels we've seen versus the benefits of a larger balance sheet and opportunities you're seeing to deploy capital into new investments as opposed to the stock buyback, and just the pros and cons and how you think about the decision there?

Kevin P. Traenkle -- Chief Executive Officer

Yes. So it's not a linear decision, and there is many variables that go into that equation. But I guess the fundamentally, we kind of start with the opportunities that we're seeing in terms of putting capital to work. We are very pleased where we're putting capital work in all of 2018. The weighted average yield on all of our investments on, over $2 billion of investments, it was over 12%. In the fourth quarter alone, it was even higher than that. So when we look at the ability to kind of put capital to work at those yields versus buying back shares, which you also rightly pointed out, does kind of shrink the balance sheet a little bit. When we kind of put it all together, it doesn't make sense right now to buy back shares, although things do change. The pipeline or robust pipeline that we have right now, that kind of takes us out over the next 90 days plus or minus. So we're feeling good about that. If the market should change and spread should tighten pretty considerably and the rates that we can get on the loans are originating change, that -- it's something that we'll always revisit and look at. But right now we're pretty happy with putting the capital to work and into our pipeline.

Stephen Laws -- Raymond James -- Analyst

All right. I appreciate the commentary on my questions and I look forward to talking to you in the future. Thank you.

Kevin P. Traenkle -- Chief Executive Officer

Thanks Steven.
