The following information is extracted from the Annual Report and Accounts 2009 and page and note references included in this information are to pages and notes in the Annual Report and Accounts 2009.

Appendix 1 : Statement of Directors' Responsibilities (page 48)

The Annual Report and Accounts 2009 contains the following statements regarding directors' responsibilities for the Annual Report and the financial statements.

Statement of directors' responsibilities in respect of the Annual Report and the financial statements

The directors are responsible for preparing the Annual Report and the group and parent company financial statements in accordance with applicable law and regulations.

Company law requires the directors to prepare group and parent company financial statements for each financial year. Under that law they are required to prepare the group financial statements in accordance with IFRSs as adopted by the EU and applicable law and have elected to prepare the parent company financial statements on the same basis.

Under company law the directors must not approve the financial statements unless they are satisfied that they give a true and fair view of the state of affairs of the group and parent company and of their profit or loss for that period. In preparing each of the group and parent company financial statements, the directors are required to:

· select suitable accounting policies and then apply them consistently;

· make judgements and estimates that are reasonable and prudent;
· state whether they have been prepared in accordance with IFRSs as adopted by the EU; and
· prepare the financial statements on the going concern basis unless it is inappropriate to presume that the group and the parent company will continue in business.

The directors are responsible for keeping adequate accounting records that are sufficient to show and explain the parent company's transactions and disclose with reasonable accuracy at any time the financial position of the parent company and enable them to ensure that its financial statements comply with the Companies Act 2006. They have general responsibility for taking such steps as are reasonably open to them to safeguard the assets of the group and to prevent and detect fraud and other irregularities.

Under applicable law and regulations, the directors are also responsible for preparing a Directors' Report, Directors' Remuneration Report and Corporate Governance Statement that complies with that law and those regulations.

The directors are responsible for the maintenance and integrity of the corporate and financial information included on the company's website. Legislation in the UK governing the preparation and dissemination of financial statements may differ from legislation in other jurisdictions.

To the best of our knowledge:
· the financial statements, prepared in accordance with the applicable

set of accounting standards, give a true and fair view of the assets, liabilities, financial position and loss of the Company and the undertakings included in the consolidation taken as a whole; and
· the management report, comprising the Chairman's Statement, the

Business Review and the Operating and Financial Review together, include a fair review of the development and performance of the business and the position of the Company and the undertakings included in the consolidation taken as a whole, together with a description of the principal risks and uncertainties that they face.

Appendix 2 : Principal Risks and Uncertainties (pages 17 to 19)

Risks and uncertainties

The Management of the Company constantly considers and reviews risk and the risk profile of this business. In addition, the Company has put in place formal processes for the identification and, where possible, the management and / or mitigation of significant risks which are reviewed regularly by senior management. This is formally reported on a regular basis to the Board, as a result of which the directors of the Company (the "Directors") are aware of the potential cost and resources involved in managing these risks. Details on the identification and management of risks are also included on page 29 in the Corporate Governance statement.

This Annual Report contains certain forward looking statements that are Wolfson's expectations and beliefs about our future business. These statements are made by the Directors in good faith, based on information available to them at the time of the approval of the report. Undue reliance should not be placed on such statements, which are based on Wolfson's current plans, estimates, projections and assumptions. By their nature, forward-looking statements involve known and unknown risk and uncertainty because they relate to events and depend on circumstances which may occur in the future and which in some cases are beyond Wolfson's control. Actual results may differ from those expressed in such statements, depending on a variety of factors. These factors include, but are not limited to: consumer and market acceptance of the Company's products and the products that use the Company's products; decreases in the demand for the Company's products; excess inventory levels at the Company's customers; decline in average selling prices of the Company's products; cancellation of existing orders or the failure to secure new orders; the Company's failure to introduce new products and to implement new technologies on a timely basis; the Company's failure to anticipate changing customer product requirements; fluctuations in manufacturing and assembly and test yields; the Company's failure to deliver products to its customers on a timely basis; disruption in the supply of wafers or assembly testing services; the timing of significant orders; increased expenses associated with new product introductions, masks, or process changes; the commencement of, or developments with respect to, any future litigation; the cyclicality of the semiconductor industry; and overall economic conditions.

There are a number of potential risks and uncertainties which could have a material impact on the Company's long term performance:

New product specification and introductions

Specifying and then designing the correct products is fundamental to the success of the Company. Customers tend to have set design windows that must be met for a product to be selected, and missing these windows through being late or not meeting the required specification can result in missing an entire end consumer product cycle. The average design cycle for the Company's products can take 18 to 24 months to complete and achieve volume production, therefore missing a cycle can take more than two years to recover. This long design cycle, coupled with limited customer visibility as to future requirements and plans, makes forecasting product demand and the timing of that demand difficult. There are also inherent risks in lengthy design cycles including risk of future design loss to a competitor, risk of cancellation and limited uptake for new products.

Dependence on the growth of the consumer electronics market

The Company's future success is dependent on the growth of the digital consumer electronics market and the successful adoption by customers of its integrated circuits in their products. The future size of the digital audio, portable devices, digital imaging markets, and other potential markets, is uncertain and depends on a number of factors, all of which are beyond the Company's control. The failure of these markets to develop as generally expected would have a material adverse effect on the business, financial condition and results of the Company's operations.

In addition, the Company's future success is also dependent on the success of its customers in their related markets. Reduced uptake by consumers of products from the Company's end customers could also have a material adverse effect on the Company's business, financial condition and operating results.

Fabless business model

The Company does not have its own manufacturing facilities. As a result, the Company's business model is less capital intensive. The Company uses GLOBALFOUNDRIES (formerly named Chartered Semiconductor), MagnaChip Semiconductor, CSMC, TSMC and X-FAB for the manufacture of most of its silicon wafers and Unisem, Carsem and ASE for major test and assembly services. The Company is reliant on these independent suppliers to provide the required capacity to manufacture, assemble and test its products and to provide high quality products on time. The Company maintains an internal manufacturing support group which directs product supply, helps ensure a high level of quality and reliability and works with the wafer foundries and production assemblers to resolve issues. As a result of the economic downturn in the latter part of 2008 and into 2009, a number of the manufacturers used by the Company have experienced financial difficulties. To mitigate the risk of loss of supply from a manufacturer ceasing business, a number of contingency plans have been put in place, including carrying additional buffer inventories and second-sourcing higher volume parts. Regular senior management meetings were also held with suppliers to ensure the Company was kept up-to-date with current trading and liquidity issues within the supply chain. As 2009 progressed, these concerns eased as the industry recovered and a major supplier was refinanced.

Infringement of third party intellectual property rights

The semiconductor industry is characterised by cross-licensing and frequent litigation regarding patent and other intellectual property rights. The Company has provided certain indemnification rights to some of its customers in respect of the infringement of third party intellectual property rights regarding its products. Claims against the Company could adversely affect its ability to market and sell its products and seriously harm its operating results. In addition, the defence of such claims could result in significant costs and divert the attention of the Company's executives and technical personnel from their day to day work.

Customer dependence

The Company supplies products to a range of companies. The Company seeks continually to expand its customer base and customer mix. However, one or a small number of customers may become responsible for a significant proportion of the Company's sales. Rapid variation of such customers' demand could then significantly affect the Company's revenues. The largest customer in 2009 accounted for 13% of revenue (2008: 13% from a different single largest customer), with the top 10 customers accounting for 63% of revenue in 2009 (2008: 63%) and the top 20 customers accounting for 74% of revenue in 2009 (2008: 78%).

Personnel

The Company relies on the ability to hire and retain appropriately qualified staff who provide the expertise and experience critical to its business and the implementation of its strategy. There is intense competition for qualified personnel in the semiconductor industry and, from time to time, the Company experiences difficulty in locating candidates in the relevant country with appropriate qualifications and experience. However, one advantage of the economic downturn has been the ability to hire more top quality graduates as a result of less competition for their services. The Company enters into employment contracts with its personnel but there is no assurance that it will be able to continue to hire and retain appropriately qualified personnel. The loss of the service of, or failure to recruit in a timely manner, key technical and management personnel (or teams) would adversely impact the Company's product development programmes and could have a material adverse effect on its performance and future growth.

Catastrophic failure of end-user device in the field

The Company supplies components primarily into consumer electronic products. Many of the major consumer brands require indemnities should a customer product recall be required as a result of significant field failures caused by one of the Company's components. The Company looks to avoid such indemnities and, where given, to limit the scope and quantum of the indemnity; however, this is often not possible and indeed some indemnities are unlimited in quantum. To reduce this risk there are rigorous procedures and controls on the design, manufacture, testing and quality processes of the Company, so as to avoid any components being supplied that could result in such field failures. The Company also has significant, but not unlimited, product liability insurance in place to cover such an event.

Competitors

The markets in which the Company operates are very competitive and are characterised by rapid technological change and evolving standards. Many of the Company's competitors are larger in size, have larger financial, marketing and/or technical resources, a longer trading history and larger installed customer bases. As a result, they may devote greater resources to the development, promotion and sale of their products than the Company can. These factors may prevent the Company from competing successfully against current or future competitors.

Acquisitions

The Company expects to review further potential acquisition targets as part of its Wolfson AudioPlusTM strategy. The internal investment case for such acquisitions may not materialise as planned. In addition, the integration of acquired companies involves additional risk including diversion of management time, potential failure to realise the synergy benefits anticipated from the acquisition, the cultural risk associated with integrating different companies in various countries, and risks associated with unexpected liabilities or events arising post acquisition.

Communication networks and information technology

The Company depends on worldwide communication links and accurate, timely information and numerical data from key information technology systems and software applications to facilitate the daily operation of the business and decision making. Any disruption caused by failings in these systems, of related equipment or of communication networks could delay, or otherwise impact, everyday decision making and some business operations. The Company has developed and tested disaster recovery arrangements in order to minimise the disruption caused by failings in these systems.

Foreign currency exposure

Appendix 3 : Related Party Transactions

('Related parties': Note 24 to the financial statements on pages 98 and 99)

Identity of related parties

The Company has a related party relationship with its subsidiaries (see notes 12 and 25), with the employee share trusts (see notes 17 and 18) and with its directors.

Transactions with key management personnel

Directors of the Company and their immediate relatives control 3.5% per cent of the voting ordinary shares of the Company. Information regarding the directors' shareholdings and share options is contained in the Directors' Remuneration Report on pages 41 and 47.

In addition to their salaries, the Group and Company also provide non-cash benefits to executive directors and contribute to a defined contribution pension plan on their behalf. The executive directors also participate in the Group's share option schemes and other long term incentive plans (see note 18). Details of the directors' remuneration are contained in the Directors' Remuneration Report on pages 34 to 47.

G Collinson was appointed as a non executive director of the Company on 1 September 2008. From April 2005 to July 2007, G Collinson served as a non-executive director of Sonaptic Limited and he was also a shareholder of Sonaptic Limited. G Collinson held 6,667 'A' ordinary shares in Sonaptic Limited. As reported in the Annual Report and Accounts of the Company for the period ended 30 December 2007, Wolfson Microelectronics plc acquired the entire issued share capital of Sonaptic Limited on 23 July 2007. G Collinson received initial consideration of $279,208 (net of professional fees and charges) at the time of acquisition, from Wolfson Microelectronics plc and, following the release of the amount of initial consideration held in escrow on 29 January 2009, a further $22,240 (net of professional fees and charges). The terms of the acquisition were such that contingent consideration was payable to the shareholders of Sonaptic Limited. Therefore, as part of the consideration for his shares held in Sonaptic Limited as at the date of acquisition, G Collinson is entitled to receive, subject to the achievement of specific business milestones, a proportion of the contingent consideration from Wolfson Microelectronics plc in accordance with the terms of the share purchase agreement entered into on 23 July 2007 between the Company and the selling shareholders of Sonaptic Limited. No amounts of contingent consideration have been paid to G Collinson by the Company either as at 28 December 2008 or at 3 January 2010. G Collinson will not participate in any discussion nor final decisions by the Board regarding the achievement of milestones and release of contingent consideration.

Other related party transactions

During the 53 week period ended 3 January 2010, subsidiaries earned commission income from the Company of $6.4 million (2008: $2.9 million) and the Company provided management services to the subsidiaries totalling $2.6 million (2008: $1.6 million). As at 3 January 2010 the Company owed the subsidiaries $3,948,000 (2008: $2,340,000) and $3,869,000 was owed by the subsidiaries (2008: $1,812,000 owed by the subsidiaries). No dividends were received from the subsidiaries in 2009 or in 2008.

There are two employee share trusts: The Wolfson Microelectronics No.1 Employees Share Trust and The Wolfson Microelectronics No. 2 Employees Share Trust. These trusts received loans from the Company totalling $nil in the 53 week period ended 3 January 2010 (52 week period ended 28 December 2008: $nil), the trusts repaid $nil of these loans (2008: $623,000) and as at 3 January 2010, $31,765,000 of these loans were outstanding (as at 28 December 2008: $31,765,000). During both the 53 week period ended 3 January 2010 and the 52 week period ended 28 December 2008, the trusts did not purchase any of the Company's shares for the purposes of fulfilling awards under The Wolfson Microelectronics 2006 Performance Share Plan, The Wolfson Microelectronics 2008 or 2009 Staff Performance Share Plans, The Wolfson Microelectronics Group Executive Shared Ownership Plan and to satisfy share option awards (note 18). There were 5,056,461 of the Company's ordinary shares held by the Company's employee share trusts as at 3 January 2010 (as at 28 December 2008: 5,378,301 ordinary shares).
