Extension of debt portfolio maturity profile

In October 2009, Investor AB launched a tender offer to repurchase a public bond maturing in 2012. The total amount being repurchased is EUR 320 m. The bond is being refinanced by a public bond with a maturity of 12 years, totaling EUR 500 m. The tender and subsequent new issue, which was heavily oversubscribed, takes advantage of current favorable market conditions to extend the debt maturity profile. Following the successful transaction, the average maturity of our debt has increased to more than 13 years from previously 12 years. A similar transaction was made in 2007.
