what period would this exam (June 2015) have been written?

Hi guys,
Could someone tell me roughly when this exam was written? I’ve heard they can be written 18 months before the exam date, but I am not 100% sure on this. Just trying to work what could be on the paper. for example, I think integrated reporting is highly likely as it wasn’t tested in the Dec 14 exam (but was tested in the P1 Dec 14 exam, as I sat this myself!)

Cheers
