Control Assumption

CFAI Reading 16 Q11 excerpt:

In December 2009, Zimt announced that it would be increasing its ownership in Oxbow to 50 percent effective 1 January 2010.

Selected Financial Statement Estimates for Zimt AG (€ Millions):

Revenue 2009 2010

1500 1700

Selected Financial Statement Estimates for Oxbow Limited (€ Millions):

Revenue 2009 2010

1200 1350

Q:Based on Gelblum’s estimates, if Zimt is deemed to have control over Oxbow, its 2010 consolidated sales (in € millions) will be closest to:

  1. €1,700.
  2. €2,375.
  3. €3,050.

The question says “if Zimt is deemed to have control
