What about relatively big changes, such as a reduction in the amortization period, which could be a maximum of 40 years in 2006, and is now a maximum of 25 years? Gradual changes have been made, but they are still significant: the maximum amortization period has been reduced by 15 years in less than 10 years.
As for changes that have had a direct impact on your business, have you been consulted in the past, or are you simply asked, at the time, what impact these changes had on your business?
