WARSAW: Poland's finance ministry estimates that over 25 percent of next year's borrowing needs have been prefinanced this year, deputy finance minister Piotr Nowak said on Monday.

The ministry also reached its goal of decreasing foreign debt to less than 30 percent, Nowak said in a statement.

Poland plans to offer treasury bonds worth 20 billion to 30 billion zlotys ($5.33 billion to $8.00 billion) at four to six auctions in the first quarter.
