| • | Beginning in the period in which the investigation revealed arrangements regarding extended payment terms for certain sales to three distributors, the Company determined it is appropriate to defer revenue recognition on all sales to these distributors from the period of shipment to the period of cash receipt. For these distributors, revenue recognition in the period of cash receipt was determined to be appropriate beginning in the fourth quarter of 2011. |

| • | Beginning in the period in which the investigation revealed return rights and profit margin protection for one distributor, the Company determined it appropriate to defer revenue recognition until the Company determines that the distributor is not entitled to any further returns or credits. For this distributor, the deferral of revenue until the Company determines that the distributor is not entitled to any further returns or credits was determined to be appropriate beginning in the fourth quarter of 2011.  At such time as this determination is made, which is currently anticipated to occur in the second half of the fiscal year 2013, previous sales for which revenue has been deferred, net of any credits or returns that may be made by the distributor, will be recognized as revenue. |
