This not only the growth on the net add side or on the gross adds side we are looking for. For that, I can also later on what is gross up churn perspective. It is also the type of customers or the bandwidths which we are gaining to our networks. We really, for us, it's really a benchmark which we gained also in Q2, which is 30% of our customers are now more than customers on the gross adds side, 400 Mb and more. This is also based on our DOCSIS 3.1 rollout, of course, because we are in the office center. Also, yeah, I, I, I mentioned cable TV also really good to look at.
What we mean with planned or actually, the housing industry churn, because later on some questions related to that. That these churns within our books, because it was sent to us last year or even the year before. When we are comparing our cable TV subscribers on net adds, we are on a much better way or track than the comparable quarters before. Also, on the premium TV, a resilient, stable business, which we are seeing here. Also in line with our expectations. Revenue remains stable compared to last year. We will see later on also some comparison to that.
Adjusted, normalized, EBITDA, because we, we, I'll explain that later, is really a big topic for us because it is an increase by 4.9%, which is outstanding, or which is what we are looking for, now performing quarter by quarter. This is what we aim for. CapEx in Q2 increases by 13%, which relates to our rollout strategy and also relates to our successful [DOCSIS] strategy on IP. Unfortunately, there was a typo in the first of your presentation. The cash position of EUR 34.3 million on the balance sheet as of June 23rd in the financial, in our financials. It's a correct one, so it is also correct here on that slide. The shareholder loan of EUR 15 million at 13% interest rate was given.
When we are now looking or coming to the operational performance, this is really what we want to see. The strong momentum in the IP, IP segment in 2020, what we saw in the Q4 continues this year. The further development of our sales channel and the orientation towards a more end customer-oriented, oriented organization. This forms our business focus. Underlined by the strong DOCSIS rollout and the high perception of high-speed customers. A good growth rate, again, 12,000 delivered, which is compared to the quarter, a good increase, and compared to the half year comparison, also a good increase. This change mainly driven by the consumer sales department, here by new channel structures as well. Both the goal and online was very strong.
We also take now care for selling new customer care, which is a change in the business. The good thing with the gross adds, when, when gross adds are okay and churn is okay or better than budget, then it's, it's what, what you want to see, and this delivers growth to the company. Telephone in line with our assumptions and also in line with our performance. When we are coming to the next page, this is really also interesting. Here we see our most important growth pillar. The German broadband market shows a strong dynamic development, and Tele Columbus has the potential to grow with this momentum. We use this opportunity to actually show growth and capitalize on this momentum, and we really outperform and want to do good for the future as well.
Comparison to our competitors is always good to keep in mind what, what they are doing. Right now, we are really putting the organization in shape to perform like in the past. Just some comparison. Here you can see on the left-hand side, half year comparison, half year 2, 2021 to 2022. That was really good. It was 1.5 acceleration. When we are now looking on half, the first half year, 2022 to the first half year, 2023, we more than doubled our, our growth. This also brings us to the growth on service revenue, which is delivered by IP.
This really is what I thought before and what we also see in our business cases for the future, is that IP is growing and growing and growing, and also the share of IP in our service revenue composition is getting bigger and will, over the future, overcompensate some losses on the TV side. Coming to the next page, is, is what I addressed before. This is our benchmark number, which we now looking at, is bring it above more and more in Q2, more than 30%, which is the lighter green and the and the dark color above. It's 92%, 500 and more. It's 2.29%, 400 megabit customers, and this we want to grow on a steady bank basis.
This is also upside potential for output growth, because looking at our base, we have potential here also to uplift low-tier customers to the higher tiers, also with by our new product ideas that we have launched in the past and we will launch in the future. Coming on to the TV business now on the next page. We have negative cable TV net adds. Two main reasons: data cleaning effect, which is a smaller one. I mentioned, I haven't shown. When you subtract these two effects from the normal business, which is then the comparison to the Q2 the year before, you end up by a 50% lower trend than the year before, which is when you also compare Q3, Q4, Q1, really a good development.
Q2 is nearly without any migration impact of large to similar contracts. This is important to mention. Same side on the premium TV side, which is also on the Q to Q level, also 50% better than the previous year. This performance, this operational performance in all our business lines and business units, then lead to the financial performance, which I also now happy to show you. On, on that slide, it is on which is fairly stable development in revenues over the past quarters, reflecting our focus on internet customers and also the success of the extension of our networks in [DOCSIS] 3.1. Here, what I explained before, you really can see the shift in the revenue segments below.
While revenue in the first half, half of the year 2022 was composed by 46% TV and 35% internet and phone, it is now 43% TV and 37% internet and phone. And this is what we are saying, that, yes, it is more than a managed shrinking of the TV business. And then we have to step in with our TC Retail and TC Wholesale strategy on ramping up on the IT side. When we are looking at comparing our revenue side on the half year 2022 to the half year 2023 results, we see a quite stable business here.
This is also what, what I mentioned several times before, exactly, that TV products are going down and are nearly compensated by our B2B work, which is good, but also on the IT side, which we're getting quite further on. Phone sales has increased by EUR 9 million. The Corona effect from 2022 to 2020 is, is flattening out, and we see lower call volumes. That is the one reason for the decline on the, on the, on the phone side. The wholesale business, which is steadily becoming stronger, leads to a revenue increase in the half year, the first half year of 2022 as well.
What we did now on the next page, this was also our discussion in the Q2, in the annual call for results of 2022, where you see the dip down by 13 point to 36 EBITDA. That was an adjustment for mainly driven by the operating CapEx shift. We normalized that on the Q-to-Q, Q-on-Q comparison. By doing that and also putting the disinvestment of [Unipix] out of the out of the comparison, which then leads to an adjusted normalized EBITDA, we really can compare apples to apples. Here we see a growth, which I mentioned before, by 4.9%.
When we look now in the on, onto page 16, to the more detailed bridge here, on the Q2 over Q2 says, decreased slightly. We have already explained the reasons for half year in detail. Other operating income, on the other hand, increased slightly by EUR 1.6 million. This effect results mainly through a depreciation interest or a release of interest accrues and asset sales. Coming to the table, TV costs are slightly lower in Q2 2023, due to a new signal cost contract, mainly with Vodafone, and due to a reduction in foreign signal costs. This results from a shift to own signal, which we also tried to do several times.... in the future.
Other direct costs are decreased by EUR 1.3 million, mainly due to higher contractual driven maintenance costs and increased energy costs. Personnel costs increased by EUR 1.2 million year-on-year, due to a combination of increased number of full-time employees and rising, rising wages. This is also reflecting our investment in consumer sales to bringing up more people on the ground, and also more external point of sales. Marketing costs de- decreased due to cost reduction measures and the postponement of projects. We've seen an increase of EUR 1.5 million in other operating expenses compared to the previous year, mainly due to rental and leasing, IT, legal, and other contract costs. As we did not have any adjustment from CapEx to OpEx in 2023, there is a positive impact of EUR 2 million here.
Okay, coming now to the last page of the presentation, which is also, yeah, completely in line with, in line with our business. What we are seeing here on the CapEx side, that the network infrastructure is going up, impacting our, our construction business. In the second half of the fiscal year, investments are rising steadily. The reasons for this is accelerated invoicing of subcontractors to the end of the year, and catch-up provisioning by project managers in Q2. CapEx to revenue ratio is at 51%, was 7.7 higher than previous year.
To be honest, what we are seeing here now, end customer-related CapEx is going up, and this leads 1 and 1 to, first of all, our higher gross add performance, and also, due to higher [bandwidth] customers, which result in higher take rates of pricier models and higher commissions. Which, to be honest, is exactly what I want to see for the future, because this leads to higher ARPU and higher [bandwidth] products. Network infrastructure investments, which I... Sorry, this I had before. A major topic here also to mention on, if you are ahead of, heads up, is that I, on IT and operation, we see a major effect into two, previously due to a temporary out of transformation projects in order to realign our transformation strategy.
For this, on that side, the IT and operations costs are lower than compared quarters. Okay, that's just the main topics of our story line for Q2. Coming now to questions you sent to us. Very important for our statement on financing is that with regards to addressing the near-term maturities and other liquidity needs, we can confirm that we are working with our advisors on addressing existing liquidity needs and maturities in our capital structure, and we are engaged with lenders, advisors, and will update the market in due course. I also like to answer some of the specific financing questions. One of the question was: Could you please provide more color on the EUR 50 million shareholder loan that the company obtained?
The EUR 50 million subordinated shareholder loan has been provided by one of our shareholders. The use of proceeds to provide additional liquidity to the company, however, is Tele Columbus AG.
Next question was: Could you please comment on how the company intends to address the upcoming capital structure maturities in 2024 and 2025, loans and bonds, and its current liquidity position?
We are working with our advisors on addressing the existing liquidity needs and maturities in our capital structure. In particular, the company is about to commence discussions with their advisor of, and ad hoc group of lenders and bondholders, and will update the market with due course.
Next question was: Given the loan matures in October 2024, I understand this must be refinanced before October 2023 to avoid a potential insolvency event within the 12-month look-forward period under German law.
From a German insolvency law perspective, there is no requirement to refinance or extend the capital structure 12 months ahead of the scheduled maturity.
Next question: What provides the management board with sufficient confidence they can raise enough liquidity funds to continue as a going concern? What commitment has the shareholders provided in terms of equity to be, to be provided? The company is in discussion with respect to a shareholder commitment to secure the funding necessary to continue as a going concern. Now they're coming from more specific questions. We refer to Goldman Sachs, who will follow up, and we will be with you. That's the part for the financing questions. Thank you for that. Now coming to the operational questions or operations questions. You already answered it, but maybe some were just later joined the call.
Cash balance on the balance sheet is stated as for EUR 34.3 million, and as the lender presentation, page five, said it's EUR 15 million. Please confirm this, this frequency. I said before, the figure of EUR 34.3 million was right. Unfortunately, there was a typo in the presentation, and we uploaded the new one, the cash position of EUR 34.3 million on balance sheet as of June 23rd, and the financials is correct. We received quite a few questions regarding fiscal year 2022 full year results, and please, on that point, this is a call for Q2 2023 financials. We will not comment on fiscal year 2022 full year questions. Please address also here on that point, our investor relations team.
Next questions. Are you trying to sell any material asset, oh, this is a good one, without affecting the B2C cable operator or the B2B business? This is very important to mention because there was an article, and also, employees are asking that the B2B business remains a cornerstone of our growth story. TC does not plan to neither sell the B2B business nor any other assets. German media reported that 100,000 of your lines were recently damaged in Berlin by a third party during construction work. Are all of these lines now repaired, and how is it expected to impact the Columbus financial? Completely repaired, everything is repaired.
No compensation to customers has to be paid due to force majeure. We are still assessing any claims and damages towards the third party who caused that damage. I'm also looking at our churn and customer inflow numbers for customer care calls and churn numbers. We don't see any impact on that damage in Berlin. I also comment on this question. I can do it again. What do you mean by housing industry plan churn? Normally in housing associations, because they also have to plan for the future, this churn comes in our company latest 6, 12, 18 months before. This is what we planned or planned or set to that planned churn. We already have it considered and in our numbers. That's the explanation.
Do you see any competition or threat from [Fixed Wireless Access] technology? Is one question. What then provided via 5G boxes. To be honest, we are... This is what we are constantly doing. We are closely monitoring our competitors' offers in the market, and we do not see [Fixed Wireless Access] technology affecting our business.
Another question is: What is the market trend on ARPU, and is there any scope for increase? In general, internet ARPUs, for example, trend to be stable, increase slightly due to price increases, as well as product mix shift towards higher speeds. This is what we are also looking for building up benchmark or just specific class management also in that company. Where we have phone usage, ARPUs remain under pressure due to lower call volumes.
This is, this is known in the market, and TV ARPUs tend to be rather stable. Other question is: Please provide an update on East and Vodafone and what the competition situation in the housing association landscape is. The competition, competition situation remains unchanged. Personal comment on that is that from the industry association, the [GDW], for example, the feedback comes, a very positive feedback, that the numbers shape this business within the management team, because they said that third party, a fourth party in the German market, for the housing association, each side, Vodafone and Vodafone, Telekom is needed.
This is also the feedback they get from their housing association members, and this is also the feedback which we get from our customers and potential customers we are addressing right now. When will the wholesale contract with Telefónica Deutschland start generating revenue? We already deliver wholesale service revenues. We are in line with our budget figures, I can say. Do you expect further cost increases in 2024? Is another question, or will the cost build out be complete after 2023? The transformation and implementation of the fiber strategy will go beyond fiscal year 2023, definitely, and in line with our customer base in the housing association side. This is a hand-in-hand approach.... With a growing top line, we will also see growing costs.
However, shifting towards a more profitable internet business, we expect a continuous improvement of our EBITDA margin.
Another question was: In the Excel toolkit revenue split, please confirm what is in other revenue? Other revenues we show wholesale, construction work, sales to program provider, [hardware] , other connection fees, and antenna servicing. Also to that question on impact to the toolkit, please come to the in the combination, colleagues, and we can lead you through. All this price increase, what are the expected sales EBITDA uplift have on the impact on churn? What we see here really is revenue increase and churn are completely in line with our expectations. Hoping that the churn pattern, which we see the first half year, also lead to a better performance on that. We'll see.
Right now, completely in line with what we expected.
Another question to premium TV: Any update on the new [OCP] platform? When will it be commercially launched? Our new hybrid I- IT platform or [OCP] platform will be launched in autumn. We are currently conducting friendly user tests, and we see very positive feedback from these testers, and excited to launch it in autumn. Where does the company stand in terms of migrating [fiber] contracts? What is the status on wholesale? m-most of, I think that is one. What is the migration part? On the migration, on the [fiber] contracts, we are completely in line on our expectations. We also match some of these ideas and get same informations from ANGA, the industry association on the, on the cable operator side.
Also the plans for 2024 are in good shape and just in executing mode.
Question to CapEx: How much is committed CapEx until year end? Also, here, completely in line with our expectations, and very important as well, completely in line with our liquidity estimates. Another question: Please point out the adjustments to adjust the normalized EBITDA in terms of [Untech] and negative cost effects from change in interpretation of accounting guidance. What was the total EBITDA contribution and proceeds we see from the [Untech] investment? The impact from [Untech] in that slide on the adjusted normalized EBITDA in Q2 2022 was around EUR 200,000. On the other side, it was EUR 2 million. Concerning the direct question to [Untech], the parties have agreed not to disclose the selling price of [Untech].
Please understand that I can't answer that question.
Question 2: In cable TV, please confirm how many customers have switched from bulk to individual contracts in half year 2023, and how many have churned, including your conversion rate? We are, like I said before, we are completely in line with our migration plan, and also with our targeted and planned conversion rates, which I claimed last time also will be something between 50%-60%. Maybe it's more for particular number, which is good. This is what we are aiming for and seeing in our first migrations.
Next question is: There was a signal cost reduction related to a lower cable TV signal fee as a result of a signal cost contract and reduction of cost for foreign signal because of shift own signal.
That was my, my comment in the presentation. Please, can you explain this in more detail and what the expected full year benefit will be? We negotiated a signal delivery contract with Vodafone, which was signed in Q1 2023, with effects of the price reduction also for the previous year, years. The parties have agreed not to disclose any further information on that. The last question, regarding CapEx, IT operations spend was materially lower due to a temporary halt of transformation projects in order to realign transformation strategy. Question is: Please, can you detail what exactly has been halted, what is being halted, and what impact this will have on your go-forward CapEx? Current architecture investments are replacing legacy systems. We have...
These have been temporarily stopped in order to reevaluate our strategy, and investments will resume in the near future and are also reflected in our business. These are the questions we received, we answered, and if any other questions on the one hand side to our operational business will arise after that call, after my answers, please email them to the, our investor relations team. Really, the address again is ir@telecolumbus.de. Like mentioned before, other questions concerning the financing, liquidity status, and so on, please address our construction. Thank you for your time. Thank you for attending our Q2 results presentation and answering your questions. Have a good day. Thank you, and see or, yeah, maybe see you again in London for some of the presentations, and hear you again for our Q3 results.
Looking forward to that. Thank you very much, and bye.
