<strong>Wavin</strong> Annual Report 2010 | page 44Information management and security measures<strong>Wavin</strong>’s ability to provide customers with products and services and manage operations continuouslydepends on the uninterrupted operation of IT systems. The <strong>Wavin</strong> activities increasingly operate acrossborders and across business functions. This requires a uniform and consistent exchange of information.To enable this, <strong>Wavin</strong> developed a <strong>com</strong>mon information system (SAP) that is gradually implementedthroughout the <strong>com</strong>pany.Governance structure for monitoring the functioning of the IT systems and to respond to developmentrequirements and extensions to the systems are in place. Technical and infrastructural IT standards toenable information systems to <strong>com</strong>municate internally and with our trading partners are mandatory.Systems, standards and IT performance are monitored and reviewed quarterly by the IT SteeringCommittee under the supervision of the Chief Financial Offi cer. The results are shared with theAudit & Investment Committee of the Supervisory Board annually.Tax<strong>Wavin</strong> has an enforcement covenant with the Dutch tax authorities as part of the ‘horizontal supervision’project initiated by the Dutch Ministry of Finance on the basis of which existing cooperation is furtherenhanced. This results in an intensive exchange of information and preliminary consultations on matterswith potentially material tax consequences. This form of cooperation fi ts within <strong>Wavin</strong>’s policy on riskmanagement in respect of taxation. In the other jurisdictions in which <strong>Wavin</strong> operates the <strong>com</strong>panypursues, where possible, a proactive policy in order to minimise any uncertainties regarding the taxpositions.Insurance<strong>Wavin</strong> has underwritten a general insurance programme to cover risks that may occur despite adequaterisk control measures, <strong>Wavin</strong> has an in-house insurance <strong>com</strong>pany for this purpose, <strong>Wavin</strong> AssurantieB.V., which insures major operating risks with independent insurance <strong>com</strong>panies. <strong>Wavin</strong> Assurantieworks together with independent insurance brokers and providers of insurance-related services.The policies cover risks resulting from property damage, business interruption, or third-party liabilityincluding product liability and a number of other specifi c risks.Audit & Investment CommitteeThe Audit & Investment Committee, which consists of three members of the Supervisory Board,independently monitors the process of risk management on the basis of the supervisory role of theSupervisory Board.

<strong>Wavin</strong> Annual Report 2010 | page 45Principal risks<strong>Wavin</strong> sells and manufactures a wide range of plastic pipe systems and solutions with a high level of<strong>com</strong>mon materials and uniform processes in operations that are located in mature and emergingEuropean markets. These markets are exposed to varying degrees of risk and uncertainty some ofwhich, if not identifi ed and managed, could have a material impact on an individual operating <strong>com</strong>pany,but may not materially affect the Group as a whole.Under the explicit understanding that this is not an exhaustive summary, major risk factors such asstrategic, operational and fi nancial risks are described below.Strategic risksGeographic exposure<strong>Wavin</strong> is dependent on the development of the construction sector in the countries in which we operate.All countries have their own economic cycle infl uenced by, amongst other factors, mortgage rates,house prices, consumer confi dence, urbanisation, the number of housing transactions and changinglegislation. Our business is concentrated in Europe where exposure to political, economic and legal risksis relatively low. The emerging economies in Europe, where we realise approximately 27% of revenue,are subject to greater risks and volatility than more mature markets. Our presence in 26 countriesmitigates our exposure to the construction cycle in any single country.Construction market exposureActivity levels in construction markets are a major driver for <strong>Wavin</strong>. The level of activity varies by marketdepending on many factors including general economic conditions, the availability of credit to fi nancebuilding activities, development of housing prices, mortgage and other interest rates, unemployment,demographic trends, weather and consumer confi dence. <strong>Wavin</strong> is active in the new-build market and inthe repair, maintenance and improvement (RMI) market for residential and non-residential developments.We are also a major player in the infrastructural construction segment. The RMI segment andinfrastructure activities tend to be less sensitive to economic cycles than new-build activities.Approximately 60% of revenue is derived from residential construction (new-build and RMI) and 40%from non-residential and infrastructural construction.Customer concentrationAmidst the consolidation in the distribution business, <strong>Wavin</strong>’s ten largest customers represented28% of revenue in 2010 (2009: 32%). The other 72% of revenue was divided over a wide customerbase.<strong>Wavin</strong> operates closely together with its distributors to service them optimally through ourEuropean presence, <strong>com</strong>prehensive product range and effective supply chain management. It is<strong>com</strong>pany policy to limit inordinate dependency on individual clients. Relationships with key customersare regularly monitored at local and group levels.Operational risksRaw material price volatilityIn the manufacturing of its products, <strong>Wavin</strong> uses large quantities of polymers such as polyvinyl chloride,polyethylene, polypropylene and polybutylene. Polymers are subject to price fl uctuations not only due tothe oil price developments but especially due to the supply and demand situation.In 2010 <strong>Wavin</strong> spent € 621 million on raw materials, <strong>com</strong>ponents and trading articles, which representsaround 50.6% (2009: 47.9%) of revenue. The price of raw materials typically changes on a monthlybasis. Contracts do not protect <strong>Wavin</strong> from price fl uctuations.As one of the largest purchasers of polymers, <strong>Wavin</strong> follows developments closely. We use our Europeanmarket leadership to pass on structural raw material price fl uctuations. Historically the <strong>com</strong>pany haspassed on a signifi cant portion of the fl uctuations in polymer prices to its customers, albeit with a certaindelay, which has led to short-term impacts on the fi nancial performance. In current markets intensifi ed<strong>com</strong>petition at the low end of the business, has stretched the time lag in passing on raw material prices.Product defect and warranty<strong>Wavin</strong> develops <strong>com</strong>plex piping, gas and water control systems which could be affected by design ormanufacturing defects or other errors or failures. This is particularly a risk with new or upgradedproducts or services as <strong>Wavin</strong>’s strict quality control procedures, or those of a <strong>com</strong>ponent supplier,could fail to test for all possible conditions of use, or to identify all defects in the design, engineering orspecifi cations of these products. (As an innovative <strong>com</strong>pany, some 15% of our revenue is realised fromproducts no older than fi ve years.) <strong>Wavin</strong> has stringent development and testing criteria and procedures
