Capitalization of borrowing cost
Under IFRS, an entity can choose to capitalize borrowing costs where they are directly attributable to the acquisition, construction or production of a qualifying asset. OMX has chosen to expense the borrowing costs incurred. Such costs are capitalized in accordance with U.S. GAAP, and depreciated as the assets concerned are used. With respect to U.S. GAAP, OMX has capitalized interest on the development of its software, Genium, which amounts to $1.4 million for the nine months ended September 30, 2007.
