This is a troubling report because there is little that Sony can do to turn things around. The games, tv, and movie division have been performing well. The yen is killing the big Japanese companies. The gaming division reported that they are still on target for their annual shipment projections for hardware and software. In fact they increased guidance on the PSP by a million imots. From a cost perspective it must be assumed that they are brining it inline with their internal goals. I assume this because it is not stated that costs are a factor in their loss this quarter.
To understand the impact of the yen, here are some general metrics you can use.
"Sony loses 7.5 billion yen ($77 million) in profit for each 1 yen gain against the euro, and 4 billion yen ($40 million) for each 1 yen gain against the dollar, he said."
"In the July-September quarter, the dollar averaged about 107 yen, down from 117 yen the same quarter last year. That dragged down Sony's sales and operating revenue by some 122 billion yen ($1.3 billion), according to the company."
"Bad times could continue for the maker of the Walkman portable as the yen last week soared to a 13-year high of about 91 yen to the dollar."
Based on this information the yen was at 107 versus the dollar at the end of last quarter. It finished trading on Wednesday at 91. That's a difference of 16 just in the most recent quarter. For every yen gain is a 40 million dollar loss for Sony. They lost $640 million in currency conversion alone this quarter.
