We have been extremely impressed with their technology and the service they have provided to us as a customer. We plan to continue building on the proprietary technology base established by Spire Semiconductor. The acquisition will permit us to focus the operation on Masimo’s custom component requirements and accelerate technology advancements in our non-invasive blood monitoring products.” The asset purchase agreement provided that the aggregate purchase price for the Semiconductor Business unit was $8.0 million plus the assumption of $500,000 in liabilities, with the cash portion of the purchase price being reduced by retained cash and liabilities assumed by Masimo in excess of $500,000.
