The Züblin Group uses interest rate swaps to hedge its exposure to future movements in interest rates. During financial year 2011/2012, Züblin entered into two new swap positions starting 30 March 2012 and 5 July 2012. These new swpas are replacing swaps which by then will mature.

All interest rate derivatives are designated as effective under the criteria of IAS 39, and as such, changes in market values of derivative financial instruments are recognized in the consolidated comprehensive income statement. The ineffective portion of cash flow hedges recognized in the income statement was CHF 0.5 million in the reporting financial year and CHF –0.7 million in the previous year.

Payments on interest rate swaps and interest payments on mortgages and other loans occurred simultaneously.
