@Daniel. FYI I believe the term Q1 2015 is ambiguous.
I suspect by the way you are using it you mean Microsoft's internal timeframe meaning Financial Year Q1. Which represents the period Jun - Aug.
Many may assume you are referring to Calendar Year. ie Jan - Mar period.
Even saying "Financial Year" doesn't help, as that changes around the world. Most commonly it is 1 July. But some countries use 1 Mar, 1 Sept & 1 Jan for their fin year start.
