BillerudKorsnäs’ activities are relatively unaffected by seasonal variations. Periodical maintenance shutdowns have the largest impact, as each unit stops production for approximately one week. This means that deliveries are somewhat lower for quite some time before, during and after the shutdown.
BillerudKorsnäs’ costs are relatively stable throughout the year. Fixed costs are slightly lower in the summer, however, due to fewer maintenance projects and lower seasonal employee benefits expense. Energy costs are slightly higher in the winter because of higher energy consumption and normally higher energy prices, especially for electricity.
In addition to ongoing maintenance while machines are running, BillerudKorsnäs’ production units normally requires a more extensive maintenance at some point during the year. To perform this maintenance, production of pulp, paper and board is stopped – known as a maintenance shutdown. The cost of a maintenance shutdown chiefly consists of lost volumes related to the shutdown and fixed costs, primarily in the form of costs of maintenance and overtime. It also comprises variable costs to a certain extent, for instance higher consumption of electricity and wood when production starts up again. The effect of the shutdown on earnings varies depending on the extent of measures carried out, their character and the actual length of shutdown. The estimated cost of the shutdown is an assessment of the impact on earnings of a normal shutdown in relation to a quarter without a periodical maintenance shutdown.

Maintenance shutdowns at Beetham, Rockhammar and Tervasaari have an insignificant effect on the company's overall earnings.
As a result of the current environmental and energy investments at Skärblacka, the maintenance shutdown in the third quarter 2013 will be longer than normal. In addition to the cost of approximately SEK 60 million for a normal shutdown, a loss of profits amounting to approximately SEK 120 million also has to be taken into account.
In the fourth quarter 2013 a shorter maintenance shutdown will take place at Gruvön. The cost for this shutdown is estimated at approximately SEK 50 million, compared to a normal shutdown of approximately SEK 100 million.
