Income from property management for the period, i.e. net income
excluding changes in value and tax, amounted to SEKm 262 (225),
equivalent to SEK 1.60 (1.37) per share. The improvement is 17% and
above all an effect of lower interest rates, but also higher rental
incomes and investments made have had a positive effect. The net
leasing amounted to SEKm -22 (25). During the period investments
totalling SEKm 298 (415) were made.

During the period, changes in value on properties and derivatives
amounted to, respectively, SEKm -397 (-171) and SEKm -109 (-44).

"The effect of the recession becomes more obvious with more
terminations and continued write downs on the properties, but we also
see lower interest rates" comments CEO Håkan Hellström. "The net
income from operations, i.e. income from property management, has
never been higher - over one billion on annual basis" adds Håkan
Hellström.
