Investment property

Hi Chris,
I hope you’re doing well. I’ve a question from Kaplan revision kit;

Smithson co purchased a new building with a 50-year life for $10 million on 1 January 2003. On 30 June 2005, smithson Co moved out of the building and rented it out to third parties. Smithson Co uses the fair value model for investment properties . At 30 June 2005 the fair value of the property was $11 million and at 31 Dec. 2005 it was $11.5 million

What is the total net amount to be recorded in the SOPL in respect of the office for the year ended 31 Dec. 2005?

By the end of 30 June 2005, the value of the building was 9,500,000. And since the fair value of property at 30 June 2005 was 11 million, there was a gain of 1,500,000. And hence that’s why I calculated this way -100 (depreciation)+1500(gain)+500(gain)= 1900 net income. But, apparently the answer doesn’t include the 1,500(gain). May I know why? I appreciate your help.
