Week 17 Analysis
Week 17 once again saw gains in both physical inspection and electrical testing results. Condition quality improved to 70% acceptance in Week 17 from 59% acceptance in Week 16 and functional performance leapt from 52% in Week 16 to 73% in Week 17. It is not overly surprising, then, that a higher percentage of acceptable product resulted in the highest volume week to-date, as measured by value.
While continuing to follow the supply chain effects of the now rebuilding process in Japan, that a significant volume of product from Japanese OCM are being sourced, the general quality level of these products has been quite good, with no rejected product in Week 17. Will continue to monitor and report on that as the impact of the natural disaster will likely have a significant impact on the industry throughout the course of 2011.

The Buddha's Birthday
Hong Kong Bank Holiday, Tuesday, May 10
It would seem strange to go an entire week without making some kind of holiday announcement, wouldn't it?
Sarcasm aside, Tuesday is another Hong Kong public holiday in recognition of the Buddha's birthday. For any of you that conduct business in any way through Hong Kong, be noted that the most non-retail businesses will not be open this coming Tuesday, May 10. This includes internet banking.
Commercial activities, including our Hong Kong facility, will all be closed on the 10th, reopening on the 11th (Wednesday).
Fortuntately, this is the last one for a while.
