Greece sold 1.137 billion euros of six-month treasury bills yesterday to refinance a maturing issue, keeping its public finances afloat. The Public Debt Management Agency (PDMA) sold the new paper at a yield of 2.97 percent, unchanged from a previous sale last month. In the rollover, T-bill holders – mostly banks – renew their positions instead of getting paid on the maturing paper they hold. The sale’s bid-cover ratio was 1.30, unchanged from the last sale. The amount raised included 262.5 million euros in non-competitive bids. Settlement date will be tomorrow. Net profit is expected to fall to between 78-88 million euros, according to Reuters calculations. Jumbo, which operates 53 stores in Greece and 19 in Cyprus, Bulgaria and Romania, said that sales for its fiscal first quarter to September rose 4.8 percent to 152.6 million euros thanks to growth in foreign markets. They are expected to rise by up to 4 percent for the full year. The Athens-listed company said it would update its forecasts after its fiscal second quarter, which includes the Christmas season.
