You mentioned that 28-nanometer is taking a bit longer. Can you kind of describe if that is relate to just maturity of the process? Was it related to just customer not ramping the design that they have and you were previously, maybe previously expect them to ramp. And finally, how much of yourself do you expect to come with 28-nanometer for the second half or for the fourth quarter of this year?

The delay of 28-nanometer is not due to their quality issue, actually we have regular tape out and it is unplanned. The July ramping is mainly because of softening economy for our customers, so customers delayed a tape out to us. So therefore, the 28-nanometer revenue contribution by the end of fourth quarter this year will be roughly above 1% of our total wafer revenue.
