Hello. Welcome to this presentation of the Q4 of 2023. My name is Susann Linde. I'm CFO and Head of Investor Relations here at Wallenstam. It has been a year with high inflation and increased interest rate and war, and so many turbulent things. Now the inflation starts to go down, and maybe soon even the interest rate. Even in those times, we as a company stand strong, both financially and have attractive properties. That's why we have this headline, Financially Strong with Attractive Properties, to our report. What have happened during this fourth quarter? We repurchased some more of our own shares, one and a half million, so now we have three million of our own shares.
We have also vacated two properties, New York to an established co-op by the tenants in the property, and it's a property in Stockholm. In Uppsala, Kvarngärdet, it's a part of the deal with Aspelin Ramm from the summer of 2021. The deal was that the property was taken over when it was fully completed, because it's a new constructed property. We have also signed a lot of commercial lettings during this quarter, and I will show you more later on. The board has proposed a dividend of 50 öre per share, and this will be paid in two pieces, the first in May and the second part in November. One more event is that Erik Klang will be a new group member from 2024, and he's a business strategist.
In this environment, there may be some transactions. It will be a good contribution to the group. From now we are six members. It's Hans Wallenstam, CFO, and Mathias Aronsson, Vice CEO and Regional Director. Hans Wallenstam is not CFO because it's me. It's he's CEO of course. We have Marina Fritsche, Vice CEO and Regional Director of Gothenburg, and me, Susann Linde, and Elisabeth Vansvik, Communication Director. Wallenstam today, a short summary of the company. We have 208 properties with a total area of 1.4 million square meter. A total property value of SEK 63 billion. 55% are residential properties. The rest commercials. The occupancy rate in total is 97%. This shows that we have an attractive property holding.
In total, we have 1,081 apartments under construction right now. Our attractive locations, they are in Stockholm, Uppsala, and Gothenburg, the growing regions of Sweden. The distribution of the rental value is residential almost 50%, and the rest is commercials. The main part or half of the rental value from commercials are from offices. In total, it's 28%, and it's almost as the same as last quarter. Our climate targets, it's the first year that we report our climate targets. All three of them has a very good outcome. If we start with Scope 1, it is minus 36%, and the reason why is because we have replaced some cooling systems with refrigerants.
Scope 2 has decreased by 24% and is a result of our energy efficiency projects, for example, additional insulation, solar cell installations, and so on. Scope 3 has an outcome of minus 90%. This target of minus 55% is very tough. We do climate calculations earlier than before, so we can change to a more climate-smart material. I think there's a good outcome from all three of the targets. On the EU taxonomy, this is the second year where we report this, but it is on a freely basis. We are not covered by the EU taxonomy regulation until financial year 2025. We have increased the green part in all three categories.
42% of our turnover is from green properties, 54% of the investments, 25% of the operating expenses that are included in the taxonomy. This is a very good work from us, I think. We come to the income statement and start with the NOI, the net operating income. It has increased by 6%, but if we take the energy price, because it has been a very high energy price, as you all may know, but we are self-sufficient. If we don't take that into account, it's an increase of 10%, not 6%. An NOI of SEK 2 billion for this year. Here are more details about what have happened in the NOI.
If we start with the rental income, it has increased by SEK 240 million, where half of it comes from the new construction and also large projects which are completed. Because of the sales and acquisitions, we lost SEK 44 million in rental income. In the comparable holdings, we have increased by SEK 151 million, and in total, it's 3.3% up for residentials and 9.1% in commercials. The operating expenses has increased by SEK 128 million, where a big part is from higher energy price by SEK 86 million. We have also done more maintenance in our properties, combined with higher taxes and inflation. In total, we have increased our NOI by SEK 112 million.
We have completed one property and 82 apartments in this Q4 , so this is not fully completed. It's in Uppsala, Kompositören, where we have 69 apartments left, which we will be completed now in this Q1 of 2024. In total, for this total year of 2023, we have completed 837 apartments. As I mentioned in the beginning, we have signed a lot of new agreements during this Q4 , and here you can see some of them. You can also see that we have a great demand for our commercial premises in Gothenburg CBD. Here are just some of the agreements. With this, we have an occupancy rate in Gothenburg of 95%, and in Stockholm, 71%. In Stockholm, we have just 10% of our total commercial area.
We have also extended agreements with many tenants. We have a lot focus on keeping existing tenants. Of all leases that expired during the year, 90% remained as a tenant. The administrative expenses has increased by SEK 21 million compared last year. This year was affected by non-recurring costs of SEK 10 million for changes aimed at adapting the organization to prevailing market conditions. The average interest rate on closing day is 3.24%, which is one percentage unit higher compared last year, which gives us SEK 300 million higher financial expenses compared last year. We have also extended our fixed interest period by extending our interest rate derivatives. It's on this. You can see that. We extended the volume from 2025 and put them to 2033 instead, which means we have no maturities of interest rate derivatives until 2026.
This cost us five basis points in the current average interest rate. It is an insurance for the future. We have almost SEK 16 billion. We have SEK 16 billion interest rate derivatives, and we have secured almost 60% of the total loan volume at a good level of interest rate and an average fixed interest rate term of 40 months. In total, the income from property management decreased by just about SEK 200 million. This quarter, we sold Kvarngärdet, which is recognized as development property sales, and it is also include other co-op units that we sold during the year. Kvarngärdet is the main part. The operating income from energy is around SEK 50 million higher compared last year if we cleared for the selling of wind turbines that we did last year.
The profit before changes in value amounts to SEK 1.2 billion, which is SEK 200 million lower than last year here as well. The changes in value, and I start with the financial instruments. At closing day, the 10-year swap decreased a lot since the start of the year. Which resulted in decreased value of the interest rate derivatives. In total, the changes in value in financial instruments are minus SEK 960 million. The share price went up by almost 11 krona during the year, and that affect the value of synthetic options to all our employees by SEK 68 million. The changes in value of investment properties is minus almost SEK 850 million. We have increased the direct yield requirements for a lot of the residential properties by 10-30 basis points and commercials by 10 basis points.
We have also written down the market value of the land for future projects, and the value has been positively affected by higher NOI, solar properties, and also completed new constructions. I made a graph here to visualize examples of our evaluation the last 13 years, and this is just examples. The yellow line is the swap rate, the 10-year swap rate, and the blue line is an example of a CBD commercial property, and the dark blue is a new constructed residential property, and the gray, an older residential property. You can see our yield requirements here. As you can see, when the interest rate was falling deep, we didn't decrease our yields so much. That is why we don't increase so much now when the interest rate is going up again. Hopefully this was a good example and you understand our valuation.
The balance sheet. This means that we have an investment property value of SEK 63 billion in our balance sheet, and it's just SEK 58 billion of the value that is investment properties in operation. The rest is ongoing projects or land and our future projects without a cash flow. We have invested SEK 2.4 billion during this year in construction, it's almost on the same level as last year. This is both in our new construction, but also in existing properties, for example, energy saving projects and refurbishments. We have this 1,081 apartments in ongoing construction. We have started one project this year.
Hopefully we can start more 2024, because you see here that we have a high demand for our product of 280,000 standing people in our own housing queue. Our interest-bearing liabilities amount to SEK 29 billion, it's SEK 700 million more on average compared the same period last year. Our funding sources, we are mainly financed through bank loans, as you all may know at this moment. Our strategy is that our investment properties will be financed through bank loans. When we issue some bonds, they will finance our wind turbines. The commercial papers, we use them instead of construction credits for our new construction. This is how we think that we will finance our operation.
Here page, you see how our distribution is in our financing. As you see, our focus is bank loans, 98%, and we have commercial papers of SEK 373 million, and one bond left of SEK 334 million, and this will expire in April 2024. To summarize with some key ratios, surface ratio 73.3%, which is has decreased if you compare last year, but the main reason is the energy price. And I haven't talked about the ICR. It's 2.6 x, and the LTV and equity ratio both are 4%-6%, we think that we have a stable financial situation.
The total repurchase shares are three million, and the equity per share is 46.4 krona per share, and the net asset value per share is 56.2 krona per share. We keep the target of 100 until 2030, of course. The summary of 2023, what have we done? We have invested in SEK 2.4 billion in our construction. We started one project of new construction, 172 rental apartments. We completed 837 apartments. We installed solar cells, 5,460, which means it's like one wind turbine. We also sold properties at the value of SEK 500 million. We signed new commercial agreements of almost 26,000 square meters.
I think that in this turbulent time that I started, I think that we have done a very good year as a summary of 2023, and we think bright about 2024. With this one, I'm happy to present the Q1 of 2024 next time. Thank you for listening. Goodbye.
