The Democratic Party of Japan envisions formulating around the end of this year a basic policy on how to restore the nation's fiscal health, including numerical targets in four years, party sources said Thursday.

The party will also consider presenting a target year in which the nation could put the primary fiscal balance of the central and local governments in the black, the sources said.

The plans are based on the premise that the party will take power and stay there for the next four years by ousting the Liberal Democratic Party-New Komeito ruling coalition in the Aug. 30 general election.
