In 2014, Gazprom voided discounts previously granted on Gas exports in Ukraine to Naftogaz. In response, Naftogaz filed a request for arbitration before the Stockholm Chamber of Commerce (SCC) for $15 billion, concurrently, Gazprom counterclaimed for the non-payment of Gas orders previously delivered up to $50 billion. On 22 December, the Arbitral Tribunal did not recognize the overpayment of Naftogaz and ordered the reimbursement of $2 billion to Gazprom for the unpaid invoice and to “take or pay” 5 billion cubic meters of gas each year beginning with 2018.
