Other income of the Group amounted to PLN 3.2 million and other expenses amounted to PLN 2.1 million in 2013, as compared to PLN 10.5 million and PLN 10.6 million, respectively, in 2012.

Other income in the periods under review was driven mainly by the following factors:

• recognition in Q1 2012 of fair value measurement of a minority stake of PolPX held by WSE before taking control (PLN 4.5 million);
• recognition of an amendment of WSE’s accounting policy concerning impairment of receivables in 2012 (release of PLN 2.9 million of provisions);
• reimbursement received from WSE employees in Q4 2012 at PLN 1.7 million in respect of the settlement of medical services as payment of outstanding contributions and personal income tax for medical packages for previous years;
• PolPX Group income in 2013 at PLN 1.0 million due to an adjustment of the VAT sale ratio for 2012 applied by the PolPX Group to deduct VAT accrued on purchase invoices;
• recognition in Q4 2013 of debt enforced from WSE clients in respect of information services at PLN 0.8 million.

Other expenses were higher in 2012 due to goodwill impairment losses on the acquisition of an organised part of the enterprise of the poee WSE Energy Market (PLN 7.9 million) and the interest in S.C. SIBEX at PLN 1.0 million.

Other expenses in 2013 mainly included provisions against irregular debt at PLN 1.3 million. In 2013, the Group paid the cost of donations at PLN 112 thousand, compared to PLN 144 thousand expensed in 2012.

Quarterly net other income and expenses were PLN 0.7 million in Q4 2013 compared to a negative PLN 0.3 million in Q3 2013 and a negative PLN 7.5 million in Q4 2012. The low net other income and expenses in Q4 2012 were driven by the cost of impairment losses recognised for poee and SIBEX.
