5e. Changes in estimates

Since 1 April 2013 the Group has changed estimated useful lives of amortized assets (property, plant and equipment and intangible assets). This has resulted in a decrease in amortization/depreciation costs by PLN 717 thousand in 2013.

In the reporting period and in comparable periods, apart from the above, the Group has not changed estimates that could significantly affect the current or future periods.
