Mustafa Tercan told broadcaster Bloomberg HT that Yildiz had agreed to an eight-year loan and offered some of its assets as collateral. He declined to say which assets.

Sources said last month that Yildiz was in talks to restructure $6.5 billion of its $8.5 billion in debt.

Investors have been increasingly concerned about Turkish firms' ability to service foreign currency-denominated debt. Chronic weakness in the lira - the currency has lost some 13 percent against the dollar this year - has driven up the cost of debt repayment.

Yildiz also owns McVitie's biscuits and Istanbul-listed biscuit maker Ulker.
