Glenn Cohen
Chief Financial Officer at Kimco Realty
Thanks Ross and good morning. We finished 2023 with solid fourth quarter results, highlighted by very strong leasing activity, increased occupancy, and improved positive same site growth. In addition, we bolstered our liquidity position ahead of our upcoming 2024 maturities and the closing of the RPT transaction. Now for some details on our fourth quarter results. The financing of the RPT transaction and our 2024 outlook. FFO for the fourth quarter was $239.4 million or $0.39 per diluted share. This compares favorably to last year's fourth quarter FFO of $234.9 million or $0.38 per diluted share.
The primary driver of the increase was higher prorata NOI of $10 million generated by our high quality operating portfolio. Our prorata interest expense was up $8 million resulting from the issuance of a $500 million unsecured bond to prefund our upcoming 24 maturities. We invested the proceeds in short term money market type funds earning $7 million of interest income, which mitigated a large portion of the dilution. In addition, during the fourth quarter we incurred $1 million of merger related expenses for the RPT transaction.
Our operating portfolio continues to deliver positive results. Same site NOI growth was positive 3.2% and if we exclude our redevelopment sites would have been 3.5%. For the full year 2023, same site NOI was positive 2.4% exceeding the top end of our same site NOI range of 2.25%. Higher minimum rent was the primary driver of the growth. As a result of our strong leasing production, the spread between leased occupancy and economic occupancy grew to 350 basis points, an increase of 30 basis points sequentially and represents $57 million in future annual base rent.
We anticipate approximately 70% of this rent to commence during 2024, providing approximately $15 to $20 million. Turning to the balance sheet, we ended the fourth quarter with consolidated net debt to EBITDA of 5.6x and on a look through basis including prorata JV debt and preferred stock outstanding of 6x, maintaining the favorable end of our target range for this metric. As mentioned previously, at the beginning of the fourth quarter we issued a new 6.4% $500 million unsecured bond which matures in 2034. This issuance addressed our 2024 bond maturities comprised of $246 million at 4.45% with an effective interest rate of 1.1% which was repaid on January 15, 2024, and $400 million at 2.7% due March 1, 2024.
Our year end liquidity position remained very strong comprised of over $780 million of cash and the full availability of our $2 billion revolving credit facility. Subsequent to year end, we monetized our remaining 14.2 million shares of Albertsons receiving nearly $300 million in proceeds. We will record a $75 million tax provision on the gain in the first quarter which will enable us to retain $224 million for future investments and debt reduction. Similar to last year, our shareholders will be eligible for a prorata credit of the federal income tax Kimco will pay. Now for some details of the financing for the $2.2 billion RPT transaction. We issued $53 million common shares to the RPT shareholders and an additional 953,000 OP units for an aggregate value of $1.2 billion.
We also converted each share of RPT 7.25% convertible preferred shares into newly issued depository shares representing 1/1000th[phonetic] of a share of Kimco 7.25% Class N Convertible Preferred stock. The class N convertible preferred stock has a liquidation preference of 92.5 million and is publicly traded on the New York Stock Exchange. Each 7.25% Class N depository share is currently convertible into 2.3071 Kimco shares. On the debt side, we paid off $130 million outstanding on RPTs revolver, repaid $514.4 million of RPTs outstanding private placement notes including accrued interest, and amended and assumed $310 million of RPT term loans.
We funded the repayment of the revolver and private placement notes from cash on the balance sheet and a new $200 million term loan with a final maturity in 2029. The $200 million term loan was swapped to a fixed rate of 4.57%. The $310 million of amended and assumed term loans are comprised of four tranches with $50 million maturing in 2026, $150 million in 2027 and $110 million in 2028. Each of the tranches has been swapped to a fixed rate with a blended weighted average rate of 4.77%.
Overall, the total debt related to RPT added to our year end balance sheet is $510 million with us using $440 million of cash on hand. Now to our 2024 outlook. Notwithstanding some of the macro factors that Conor mentioned earlier, we remain confident about the growth prospects of our operating portfolio and are enthusiastic about unlocking the potential of the newly added RPT assets. Our initial 2024 FFO per share guidance range is $1.58 to $1.62 before any RPT merger related costs, which we expect will be in the $25 million range or $0.04 per diluted share.
Our guidance range is based on the following assumptions. Same site NOI growth of positive 1.5% to 2.5% inclusive of the RPT assets included in the same property NOI guidance range is a credit loss assumption of 75 basis points to 100 basis points. This is a similar level to our credit loss experience in 2023. Lease termination income between $1 million and $3 million. This is compared to $7 million in 2023. Interest income between $2 million and $4 million as compared to $19 million in 2023 as we had significantly higher cash balances during '23.
Acquisitions, including Structured investments ranging from $300 million to $350 million weighted toward the second half of the year. Dispositions ranging from $350 million to $450 million weighted toward the first half of the year comprised primarily of select RPT assets. Corporate financing costs ranging from $319 million to $325 million comprised of consolidated interest expense and preferred stock dividends. Annual G&A expense ranging from $133 million to $139 million. The G&A range is inclusive of the expected cost saving synergies from the RPT transaction ranging from $30 million to $34 million.
Our guidance range also assumes no material impact from RPT related non cash GAAP accounting income comprised of above and below market rent amortization, straight line rents, and fair market value adjustments to debt. Lastly, the guidance range assumes no redemption charges or prepayment charges associated with callable preferred stock outstanding or early repayment of debt obligations, and no planned issuance of additional common equity.
I want to thank all our associates whose tireless effort brought the RPT transaction to a successful closing and drove our strong results to end the year. We look forward to a successful 2024 together. And with that, we are now ready to take your questions.
