Stable income from property management and positive net leasing

   * Rental income for the period January-June 2013 amounted to SEKm 1,622 (SEKm
     1,521 corresponding period previous year).
   * Income from property management amounted to SEKm 634 (606), corresponding to
     SEK 3.87 (3.70) per share, an increase with 5%.
   * The changes in value on properties amounted to SEKm 119 (28) and on
     derivatives to SEKm 387 (109).
   * Net income after tax for the period amounted to SEKm 902 (580),
     corresponding to SEK 5.50 (3.54) per share.
   * Net investments amounted to SEKm 846 (735) of which SEKm 799 (613) were new
     constructions, extensions and reconstructions, SEKm 152 (333) acquisitions
     and SEKm 105 (211) sales.

Gross leasing (i.e. the annual value of total leasing) during the period was
SEKm 187 (154), of which SEKm 48 (25) were leasing of new constructions,
extensions and reconstructions. Notices of termination amounted to SEKm 125
(141), of which bankruptcies were SEKm 13 (14) and SEKm 9 (17) were notices of
termination with more than 18 months remaining length of contract. Net lease for
the period was hence SEKm 62 (13) and for the second quarter SEKm 35 (21).

"Castellum's income from property management increased 5%, despite a hard winter
with a cold first half-year and a weak business cycle", comments CEO Henrik
Saxborn. "The net leasing is positive during the first half-year, mainly due to
leasing in new projects", Saxborn adds.
