Continued outperformance in financial market turmoil

During the third quarter we experienced an extreme financial turmoil, torturous in nature, which has further escalated into the last quarter of the year. The US-led credit crisis and economic downturn have

now spread to other parts of the world. As a result of this turmoil, our Net Asset Value was down by six percent. However, the total return for the Investor share was flat during the third quarter. For the full nine month period the total return was an unsatisfactory minus ten percent, but that compares favorably with the general market return (SIXRX) of negative 27 percent.

During the quarter, the credit crisis sent shock waves around the globe's financial markets. It started as a US problem, but we now also see bank failures in Europe. Lack of liquidity has been a key concern including the malfunction of the inter-bank lending market. However, we must not forget that major drivers of the crisis are excessive leverage and poor asset quality indicating a need for new equity in the global bank system.

We have earlier discussed the unsustainability of the low risk premiums in the market and expressed our concern for its longer term consequences. Well, here we are. Ten years or more of low or periodically negative real interest rates have built up large excesses. Basically capital has been too cheap and too easily accessible. It will take time to work out this situation. As financial institutions clean up their balance sheets and de-lever, access to capital has tightened. This makes buy-out transactions but also real investments in production equipment more difficult.

European growth is rapidly slowing and there are signs of slowdown in the BRIC countries. While I still believe the BRIC countries can provide some balance to the slowdown in the US and Europe, they will not be unaffected. How deep and long this downturn will be I leave to the macro economists to predict, but I think we should plan for it to be relatively severe. It is positive that central bankers and politicians across the world have acted forcefully to stabilize financial markets and meet the economic slowdown. The coordinated initiatives between countries that we have seen during the last days, i.e. introduction of extensive guarantees to restore confidence in the credit market, are good steps in the right direction. Let us however not assume quick results, restoring confidence takes time. I am fundamentally an optimist and believer in our economic system. I am thus convinced the current environment will provide excellent investment opportunities in a 3-5 year perspective.

Well structured variable compensation programs are value creating

There needs to be a discussion about the underlying factors behind the current financial turmoil. Right or wrong, lack of sufficient regulation and the impact of the new accounting rules have been mentioned. Executive compensation has also been raised as one critical factor. No doubt the US executive compensation has in many cases been unacceptably high, even if a large part of the compensation is paid in equity or options, instruments that are now worthless. Too much focus on short term performance has in many cases led to wrong incentives, driving unhealthy risk-taking.

I remain a believer in variable compensation when correctly structured. It creates a common focus on important objectives and leads to a variable cost base for the company. However, it is important to combine the return potential from the incentive system with downside risk. A good way is to have management teams invest a substantial part of their net worth in shares in the company, thereby putting their own capital at risk. If value is built up longer-term, managers will share part of the upside with the shareholders, potentially becoming financially independent. If the company does not perform, managers will share the downside, and pain, with the shareholders. This however requires well structured, but simple and understandable compensation systems, focused on aligning interest with the owners on creating longer term shareholder value. In this context, it may be appropriate to review the extensive use of short-term performance benchmarks in long-term compensation programs, since these can lead to an undesired behavior from a shareholder perspective.

Core Investments outperforming market

It is satisfying that our Core Investments portfolio has outperformed the market and overall, that the companies are financially strong. Furthermore, the current environment may give rise to attractive opportunities for acquisitions. Investor is in a strong financial position allowing us to support our companies if they pursue attractive industrial transactions by participating in capital raises.

The sale of our shares in Scania was completed in mid-July. Together with the sale of OMX, finalized earlier in the year, this has led to a cash inflow of SEK 20 bn. During the quarter we have taken the opportunity to make small increases in some of our Core Investments. Although public markets are likely to remain volatile, we try to take advantage of opportunities when the stock prices of our holdings fall below what we view as their long-term fundamental value.

Once again, dear shareholders, I regret investing your capital too early when adding on to the SEB position this year. Although stock markets are likely to remain volatile, I still believe in the value potential of SEB in 3-5 years.

Progress within Operating Investments

During the summer we closed the previously announced deal to acquire Lindorff, jointly with Altor. The current macro environment should offer good opportunities for Lindorff to further grow its business. The company has a solid financial position and we are prepared to inject more capital if significant acquisition opportunities arise.

Mölnlycke Health Care's growth strategy and investments in product development are starting to pay off. The company is expanding the geographic reach, increasing the size of sales force in each market, and making acquisitions. In constant currencies, the top line and EBITDA growth is holding around 10 percent despite the environment.

CaridianBCT's growth remains strong with the newly launched state-of-the-art products Atreus and Mirasol getting traction with customers. Gambro is still burdened by previous under-investments in R&D, quality and infrastructure simplifications. This year, for the first time in many years, the company is launching several new products - including two new monitors (Artis and AK96) for renal chronic treatment. This will be the first time since 2001 that new HD monitors are being introduced by Gambro. Gambro is making good progress, but significant restructuring is still required in order for the company to regain its industry leadership position. The current financial position may put restrictions on the speed of change but we are willing to invest additional funds if it is required and value-creating.

The positive development of 3 Scandinavia that led to the EBITDA break-even milestone reached during the summer, has continued during the quarter. The company has added additional 101.000 customers during this quarter alone.

Debt financing for Gambro, Mölnlycke and Lindorff are structured to reflect each companies characteristics and are all long in maturity and ring-fenced, without guarantees from Investor. As communicated earlier, Investor guarantees it's share of the debt financing of 3.

Mixed performance within Private Equity

Investor Growth Capital recorded a slight value increase during the quarter. A decrease in local currency was more than compensated for by positive currency effects. We see that some sectors, like software, are starting to be effected by a generally slower economy.

The value of the EQT portfolio fell mainly as a consequence of contracting multiples for comparables but also to some extent as a result of falling operational metrics. The high leverage used in buy-outs certainly puts extra demands on managing the companies extraordinary well. In this context it is worth noting that EQT has a strong track-record also in tough economic conditions.

New tax proposal

A new tax proposal that impacts Sweden-based investment companies has been presented. The deductibility of interest payments has been limited, thereby creating an extra cost burden for Swedish investment companies. The proposed model creates uncertainty and additional administration.

All in all, if it goes through, it may put Swedish investment companies at a competitive disadvantage compared to other types of investors. What longer term effects this will have on Sweden-based ownership remain to be seen.

Need for increased competitiveness of the public market

The current environment will offer opportunities for our holdings to strengthen their market positions, for example through acquisitions. A key success factor will be to have rapid access to capital. Making a rights issue in a turbulent market is difficult, potentially even jeopardizing the success of an acquisition. Therefore I would once again like to stress the importance of facilitating directed rights issues for listed Swedish companies by giving the board a mandate. This would speed up a capital raising process and be value creative for all shareholders.

Another complicating factor for M&A transactions in the Swedish public market is the current legislation, that in practice requires 90 percent support from shareholders in order for a cash offer to be consummated. This high threshold may even be a restriction for launching value creating efforts. Once again, the execution risk becomes too high and a failed bid has a negative effect on the bidder's operation and credibility. Basically a ten percent minority can dictate the outcome of a bid without any responsibility for all the other shareholders. This is another area to look into in order to make the public market more efficient and facilitate industrially sound transactions.

Strong financial position

In the Q2 report I used the subtitle from the movie Jaws 2 to describe the market sentiment. This time around I will not. A sequel would never be financed in this market.

Being in a strong net cash position is very gratifying and the result of our strategy of ensuring a solid financial position. We are convinced that the coming year will offer attractive opportunities. As previously communicated, our strategy is to expand our Operating Investments, make selective investments within Core Investments and continue to build our Private Equity operations. With a professional and dedicated organization, combined with a strong balance sheet, we are ready to act on opportunities. We will remain disciplined and pursue only those we truly believe will lead to attractive returns for our shareholders longer term. Courage to take risk will be important – well illustrated by this quote attributable to the legendary basket ball player Michael Jordan: "I've missed 9,000 shots in my career, I've lost almost 300 games. 26 times, I've been trusted to take the game winning shot and missed. I've failed over and over again in my life. And that is why I succeed". But equally important will be patience - being an investor in this environment is like watching paint dry.

Stock markets have been severely burdened by the ongoing credit crunch and the clear effects on the real economy. Consequently, the stock prices of Core Investments have been negatively affected, though as a portfolio they outperformed the general market.

Purchases and sales

In Atlas Copco, 2,000,000 A-shares and 2,000,000 B-shares were purchased for a total of SEK 324 m.

In SEB, 1,000,000 A-shares were purchased for SEK 128 m.

In Electrolux, 1,000,000 B-shares were purchased for SEK 80 m.

In Husqvarna, 1,000,000 A-shares and 375,000 B-shares were purchased for a total of SEK 69 m.

In Scania, 88,027,028 shares were sold for SEK 16,807 m.

Events occurring earlier during the year

Earlier in the year, shares in SEB were purchased for SEK 595 m., in Husqvarna for SEK 249 m., in Electrolux for SEK 145 m. and in Atlas Copco for SEK 55 m. The position in OMX was divested for SEK 3,412 m.

Redemption programs

Earlier this year Investor sold Scania redemption rights for SEK 660 m.

Core Investments had an impact of SEK -18,025 m. on income in the first nine months of the year (14,060), of which SEK -7,430 m. was in the third quarter (-6,088). Scania had a positive impact of SEK 3,295 m. for the

period. ABB and SEB had negative impacts of SEK -8,518 and SEK -7,598 m., respectively.

Operating Investments

Operating Investments had an effect of SEK -173 m. on income during the first nine months of the year (-432), of which SEK -166 m. was in the third quarter (-533). The acquisition of Lindorff was finalized during the quarter. Operating Investments, except for The Grand Group, are reported with one month's delay.

Earnings for the period

Operating Investments had an effect on Investor's income of SEK -173 m. (-432), of which SEK -456 m. was attributable to 3 Scandinavia (-664), SEK 307 m. to Mölnlycke Health Care (-100) and SEK -31 m. to Gambro Holding (28). Lindorff is carried at acquisition cost in this report and thus has no effect on income.

In the third quarter, Operating Investments had an effect of SEK -166 m. on income (-533), of which SEK -129 m. was attributable to 3 Scandinavia (-207), SEK 73 m. to Mölnlycke Health Care (-99) and SEK -159 m. to Gambro Holding (-253).

The weakening of the Swedish krona (SEK) resulted in a positive currency translation effect on the reported net asset value figures for Mölnlycke Health Care and Lindorff.

During the first nine month of the year, total investments amounted to SEK 4,419 m. of which Lindorff accounted for SEK 3,504 m. and further investments in 3 Scandinavia for SEK 719 m. The increase in market value of Lindorff compared to the initial investment is currency related, and is offset by a cross currency swap in Investor's financial net.

VALUATION METHODOLOGY WITHIN OPERATING INVESTMENTS

In the Operating Investments business area, Investor normally has majority ownership or a stake with significant influence in the underlying investment. Investments classified as associated companies are reported using the equity method and subsidiaries are fully consolidated. Investor's share of the holding's equity constitutes the valuation of the holding when the equity method is applied and Investor's share of the holding's net result is included in the income statement. Thus, for companies incurring large costs that impact short-term profits negatively, the value of the holding declines in Investor's net asset value. As a consequence, Investor is now providing key operating figures, such as normalized EBITDA and net debt, in order to facilitate the market's evaluation of these investments. In normalized EBITDA, one-off items, such as restructuring costs, certain amortization items and write-downs, and specific investments, are eliminated to better reflect the underlying result. Figures for Mölnlycke Health Care, 3 Scandinavia, CaridianBCT and Gambro are reported with one month's delay. Quarterly figures refer to the period June 1, 2008 to August 31, 2008.

Although most venture stage companies do little borrowing, the credit crisis is having an impact on the venture capital business. For example, there has been just one venture-backed IPO in the U.S. since March. M&A activity has also declined sharply, down about 25 percent year on year. However, the weak stock market is resulting in much lower valuations of potential new investments.

INVESTOR'S PRIVATE EQUITY INVESTMENTS

Private equity investments have been made since Investor was established in 1916 but were given their current modern shape and structure in the mid-1990s. The private equity activities generate high returns when exits are realized, allow for increased diversification of the portfolio, synergies with the core investments and the possibility to discover important new technologies and new business trends early.

Investor conducts two different types of private equity investments: venture capital investments in young growth-oriented companies and loan-financed investments (buyouts) in medium to large size companies that are more mature and have development potential. Venture capital activities are conducted by Investor Growth Capital, a wholly owned subsidiary. Buyout activities are conducted through EQT's funds, which are partly owned by Investor. Investor Growth Capital is active in the United States, Northern Europe and Asia. EQT, partly owned by Investor, has 12 funds focused on companies in Northern Europe and Greater China.

Investments in private equity, which involve more risk by their nature, are made with the objective of realizing an average annualized return (IRR) of 20 percent.

Financial Investments

The business area had an effect of SEK -257 m. on income in the first nine months of 2008 (29), of which SEK -206 m. was in the third quarter (-43).

Earnings for the period

Financial Investments had an effect of SEK -257 m. on income in the first nine months of the year (29), of which SEK -206 m. was in the third quarter (-43). The negative value contribution within the business area during the third quarter derives mainly from RAM One.

Active Portfolio Management

Investor's Active Portfolio Management unit generated operating income (dividends and value changes but before operating costs) of SEK 36 m. during the first nine months of the year(117), of which SEK -69 m. was in the third quarter (-30).

Investor's Active Portfolio Management has a limited risk profile. The activity is limited to trading in equitybased instruments. The risk mandate, which is periodically changed, is defined on the basis of Valueat-Risk (VaR). The VaR limit is currently SEK 45 m. and is based on a one-day time horizon and a 99-percent confidence interval. Gross investments, i.e. before hedges for market risk, normally amount to approximately 1 percent of Investor's total assets. In addition, Active Portfolio Management uses different types of market-listed derivative instruments to hedge a large portion of the market risk. The actual net exposure is generally less than the value reported for Active Portfolio Management in the net asset value table (see table).

RAM One

The hedge fund RAM One changed by -14 percent during the first nine months of 2008 (8), of which -12 percent during the third quarter (-2.5).

Group

Consolidated net debt

The consolidated net cash position totaled SEK 10,831 m. on September 30, 2008, compared to a net debt of SEK 3,583 m. at the beginning of the year. Investments in the Operating Investments business area such as Mölnlycke Health Care, Gambro Holding and Lindorff, that are not subsidiaries, are financed in ring-fenced stand-alone structures and are consequently not included in Investor's consolidated net debt. 3 Scandinavia's debt, of which Investor's share is SEK 4.2 bn. (excluding interest), is guaranteed by the owners but is not included in consolidated net debt.

Net financial items for the reporting period amounted to SEK -259 m. (-217). Net financial items include interest income of SEK 617 m. (407) and interest expenses totaling SEK 790 m. (799). The remaining portion consists mainly of revaluations of loans, swaps and the effects of hedges for long-term share-based remuneration programs.

Cash, bank balances and short-term investments amounted to SEK 29,482 m. on September 30, 2008, compared to SEK 15,008 m. at year-end 2007. The Group's borrowings totaled SEK 19,260 m. at the close of the quarter, compared with SEK 19,109 m. on December 31, 2007.

The average maturity of the debt portfolio was 12.8 years on September 30, 2008, compared with 13.6 years on September 30, 2007.

Dividends totaling SEK 3,637 m. were paid to Investor AB shareholders during the second quarter (3,449).

Consolidated costs

Consolidated costs totaled SEK 400 m. in the first nine months of the year (392). Costs per business area are shown in the segment reporting section on page 23.

The calculation of commitments within the framework for employee stock option programs and share programs resulted in additional costs of SEK 19 m. during the period (24). Since the programs launched up to 2005 are hedged with derivative instruments, there is a corresponding effect of the hedging in net financial items. The purpose of the hedging is to minimize costs for the programs that arise in connection with increases in Investor's share price.

Parent Company

Share capital

Investor's share capital amounted to SEK 4,795 m. on September 30, 2008 (4,795).

During the third quarter, Investor did not repurchase any of its own shares. On September 30, 2008, Investor owned a total of 2,483,800 of its own shares (1,400,000). The average number of own shares during the reporting period amounted to 2,026,409 (1,123,077).

Results and investments

Total debt decreased by SEK 13,041 m. since the beginning of the year. The decrease was mainly due to changes in balances with Group companies. Equity totaled SEK 103,785 m. on September 30, 2008, compared with SEK 101,564 m. on December 31, 2007.

The Parent Company's result after financial items was SEK 5,986 m. in the first nine months of 2008 (14,345), of which SEK 5,881 m. consisting of changes in the value of equity-related holdings reported at fair value (12,462) and divestments, such as Scania and OMX. The majority of the Core Investments are associated companies and are therefore reported at the lower of acquisition cost or fair value in the Parent Company. In the Group, the holdings are reported at fair value. This explains the difference in the value change between the Group and Parent Company for these holdings in 2008. Write-downs of participations in associated companies totaled SEK -3,365 m. (-707) and were mainly attributable to Ericsson and Husqvarna. Writedowns of participations in Group companies had an effect of SEK -37 m. on net financial items (-).

During the nine-month period, the Parent Company invested SEK 6,469 m. in financial assets (11,352), of which SEK 4,113 m. was in Group companies (5,837). Sales of financial assets amounted to SEK 21,358 m. mainly Scania (6,002). No holdings were sold in Group companies during the quarter.

Investor shares

The total return (sum of share price changes and reinvested dividends) was -10 percent in the first nine months of the year (2), of which 0 percent in the third quarter (-7).

The average annualized total return on Investor shares has been 18 percent over the past five-year period. The total return over the past ten-year period was 9 percent. The corresponding figure for the past 20 year period was 13 percent.

The price of the Investor B-share was SEK 127.25 on September 30, 2008, compared with SEK 147 on December 31, 2007.

Risks and uncertainties

Significant risks and factors of uncertainty for the Group and Parent Company include commercial risks in the form of high exposure to a certain holding or sector, of which some, such as the industrial sector, are characterized by cyclical demand. There is also a general risk of value depreciation of holdings linked to the development of the global economy. In addition, there are financial risks mainly in the form of price risks – the risk that the value of a financial instrument, such as shares and debt instrument might change because of fluctuations in prices, exchange rates or interest rates.

There are also risks towards counterparties, such as financial institutions. These have increased further during the third quarter given the turbulent credit market.

Other

Accounting policies

For the Group, this interim report has been prepared in accordance with the Swedish Annual Accounts Act and IAS 34 Interim Financial Reporting, and for the Parent Company in accordance with Sweden's Annual Accounts Act and Recommendation RFR 2.1 – Accounting for Legal Entities, issued by the Swedish Financial Accounting Standards Council. Unless otherwise specified below, the accounting policies that have been applied for the Group and Parent Company are in agreement with the accounting policies used in the preparation of the company's latest annual report.

New accounting policies in 2008 and restatement of comparative figures for 2007 As of fiscal year 2008, Investor is applying IFRIC 11, IFRS 2 – Group and Treasury Share Transactions, which addresses how share-based payment arrangements are to be classified in entities that receive services from their employees. Up till December 31, 2007 the total cost of the share-based payment for the employees in Investor Group were recorded in the Parent Company. IFRIC 11 states, in cases where a Parent Company grants rights to its equity instruments to employees of a subsidiary, the cost calculated in accordance with the interpretation is to be recognized as a capital contribution to a subsidiary that receives services from its employees. In accordance with the transition regulations, this interpretation is being applied retroactively and has affected the Parent Company's equity and participations in subsidiaries for fiscal year 2007 by SEK 20 m. The effect on the Parent Company's results for the reporting period January to September 2007 was SEK 3 m. compared to previously published report.

From 2008 the cost incurred for the share-based payment arrangements will be invoiced to the subsidiaries and cash settled on a timely basis.

Other new or revised IFRS principles and interpretations of the IFRIC have not had any effect on the financial position or results of the Group or Parent Company.

Significant accounting and valuation policies The following is a brief description of the accounting policies that are of central importance to the preparation of Investor's financial reports.

Accounting and valuation of holdings

Subsidiaries

Companies that are defined as subsidiaries are consolidated in the Group in accordance with the purchase method and IAS 27 and IFRS 3. In the Parent Company, subsidiaries are reported in accordance with the acquisition value method.

Associated companies

For the Group, Investor's main rule is that associated

companies are reported as financial instruments, at fair value, in accordance with IAS 39 and IAS 28, paragraph 1. Associated companies in the Operating Investments business area are reported in accordance with the equity method since Investor is involved in the companies' business activities to a larger extent than in holdings in other business areas. In the Parent Company, associated companies are reported in accordance with the acquisition value method.

Holdings reported within several business areas In cases when a holding is reported in several business areas, and the measurement and accounting principles differ, the valuation method applied to the relatively largest share of the holding is also used in the other business areas.

Other holdings

All other holdings are reported and valued as financial instruments in accordance with IAS 39. See also below.

Financial instruments

Equity-related investments

In accordance with IAS 39, equity-related investments are reported at fair value through profit and loss. Equity-related investments are valued as follows:

Listed holdings

Listed holdings are valued on the basis of their share price (bid price, if there is one quoted) on the closing date.

Unlisted holdings

Unlisted holdings are valued on the basis of the "International Private Equity and Venture Capital Valuation Guidelines" prepared and published jointly by the venture capital organizations EVCA, BVCA and AFIC. However, holdings in the Operating Investments business area are valued either as associated companies or subsidiaries (see above).

For directly owned holdings (i.e. those owned directly by a company in the Investor Group), an overall evaluation is made to determine the valuation method that is appropriate for each specific holding. It is first taken into account whether a recent financing round or "arms length" transaction has been made, after which a valuation is made by applying relevant multiples to the holding's key ratios (for example, EBITDA), derived from a relevant sample of comparable companies, with deduction for individually determined adjustments as a consequence of, for example, the size difference between the company being valued and the sample of comparable companies. An assessment is then made of the above-mentioned methods to determine the one that best reflects the market value of the holding, and the holding is then valued according to that method. In those cases when other valuation methods better reflect the fair value of a holding, this value is used, which means that certain holdings are valued with methods other than the ones described above.

Fund holdings

Holdings in funds are valued at Investor AB's share of the value that the fund manager reports for all holdings in the fund and is normally updated when a new valuation is received. If Investor AB's assessment is that the fund manager's valuation does not sufficiently take into account factors that affect the value of the underlying holdings, or if the valuation is considered to deviate considerably from IFRS principles, the value is adjusted.

Liabilities

Investor AB uses derivatives to control the exposure of the debt portfolio against fluctuations in exchange rates and interest rates. Hedge accounting is applied to reflect this in the consolidated accounts in cases when a derivative and the underlying loan qualify for this in accordance with IAS 39. When loans and derivatives do not qualify for hedge accounting, loans are valued at the amortized cost and derivatives are reported at fair value through profit and loss.

Other financial instruments

Derivatives and short-term investments are reported at fair value through profit and loss.

Financial instruments other than those noted above are reported at the amortized cost.

Property, plant and equipment

In accordance with alternatives in IAS 16, Investor AB's real estate properties are reported at fair value.

Share-based payment

Investor's employee stock option programs and share programs are reported in accordance with the regulations in IFRS 2 for share-based payments that are equity settled. A value for the program is estimated on the grant date which then comprises the basis for the cost that is distributed over the vesting period of the programs. Provisions for social security costs are reported on a continuous basis in accordance with UFR 7 and are thus distributed in the same way as the cost for employee stock option and share programs.

Taxes

The valuation of assets and liabilities at fair value results in temporary differences when the fair value differs from the tax value. In accordance with IAS 12, a deferred tax liability, or deferred tax receivable, is recognized for temporary differences.

Deferred tax receivables resulting from temporary differences, or due to loss carry-forwards, are recognized only to the extent to which it is probable that it can be realized against taxable profits within the near future.

Other

Changes in value

For items that were held in the balance sheet at the beginning and at the close of the period, the value

change consists of the difference in value between these two dates. For items in the balance sheet that were realized during the period, the value change consists of the difference between the proceeds received and the value at the beginning of the period. For items in the balance sheet that were acquired during the period, the value change consists of the difference between the value at the close of the period and the acquisition cost.

Review Report

Introduction

We have reviewed the interim report for Investor AB as per September 30, 2008 and the nine-month reporting period ending on that date. The Board of Directors and the President are responsible for the preparation and presentation of this interim report in accordance with IAS 34 and the Annual Accounts Act. Our responsibility is to express a conclusion on this interim report based on our review.

Focus and scope of the review

We conducted our review in accordance with the Standard on Review Engagements SÖG 2410, "Review of Interim Financial Information Performed by the Independent Auditors of the Entity". A review consists of making inquiries, primarily to persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review has a different focus and is substantially less in scope than an audit conducted in accordance with Standards on Auditing in Sweden RS and other generally accepted auditing practices in Sweden.

The procedures performed in a review do not enable us to obtain a level of assurance that would make us aware of all significant matters that might be identified in an audit. Therefore, the conclusion expressed on the basis of a review does not give the same level of assurance as a conclusion expressed on the basis of an audit.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the interim report is not, in all material respects, prepared for the Group in accordance with IAS 34 and the Annual Accounts Act, and for the Parent Company, in accordance with the Annual Accounts Act.
