In case of a successful acquisition, Macquarie Group Ltd. will split UK Green Investment Bank Plc into at least two different units rather than stripping it of its assets, though it may sell some of them, Bloomberg News reported Jan. 26, citing "two people familiar with the matter."

Under the plan, one unit would focus on deals that are yet to close, while at least one other unit would manage existing loans. Green Party lawmaker Caroline Lucas told Bloomberg that news of the plan did not reassure her.

The Macquarie bid has been met with resistance, and the U.K. government is reportedly also considering an IPO for GIB.
