Example 2 Basic Consolidation

Dear Sir,
I came across the example on basic consolidations, and I have a question.

It says in the qn that the sub’s (Finn’s) net assets value in the statement of financial position is $1250 mn and then the qn says
“At 1 January 2014, the identifiable net assets of Finn had a fair value of $1,850 million”

Shouldn’t the excess in fair value be $600mn? In the notes, the answer says $400 mn increase.

What am I missing? Or am I right?

Thanks.
