In addition to the above-mentioned acquisition-related payments, the cash flow before financing activities due to the increase in turnover requirements increased by 173 million euros compared to 2007. At the same time, due to the higher investment in solid-state lighting solutions, the company's net capital expenditure also increased by 54 million euros.

Given that the economic outlook may continue to deteriorate, PHILIPS believes that 2009 is a very challenging year. The company must not only continue to maintain the contract volume in the construction and automotive markets, but also strive to maintain consumer confidence in most emerging markets. In this environment, PHILIPS said it will proactively expand the reorganization plan, choose more effective cash management measures to further reduce (fixed) costs last year, and ensure that in 2009, investors will be presented with a favorable balance sheet. In order to achieve stable financial management, the company will stop the share repurchase plan, and will continue to closely manage the company's market and competition situation. PHILIPS hopes that through strict cost and cash management, coupled with a strong brand and balanced portfolio advantages, it will be able to survive the current economic turmoil, and when the economic conditions recover, it can achieve a more powerful goal.
