TDC, Denmark’s leading mobile operator in terms of subscribers, has published its financial report for the three months ended 31 December 2013, reporting a 6.1% annual drop in revenue to DKK6.149 billion (USD1.11 billion), down from DKK6.548 billion in 4Q12. The slump is mainly attributed to the regulation of international roaming charges, as well as domestic mobile termination rates (MTRs), which were slashed nearly 68% in 2012. According to TDC, the reduced rates impacted on its bottom line by around DKK656 million. Gross profit dropped to DKK4.401 billion in the period under review, down 3.7% from DKK4.572 billion in the corresponding period one year earlier, while EBITDA declined 1.0%, from DKK2.573 billion to DKK2.547 million year-on-year.
