HRE, which employs around 1,800 people, was also in talks on other measures to protect its activities with the German government's financial stabilization fund, or SoFFin, the magazine Der Spiegel reported.
A spokesman for the bank contacted by AFP declined to comment on the report. On December 10, the specialist in property financing said it would receive €30 billion ($42.7 billion) in state loan guarantees rather than €20 billion under a government rescue plan for the banking sector.
HRE, Germany's biggest victim of the banking crisis, and its Irish subsidiary Depfa, were caught in a liquidity crunch that worsened after the US investment bank Lehman Brothers declared bankruptcy in mid September.
HRE has already benefited from a rescue plan worked out by the government and the German central bank worth €50 billion.
