Note 17 - Acquisition s In the fourth quarter of 2012, we acquired three privately held companies. The companies acquired included a wireless product company with a focus on test and measurement, a network measurements company with an emphasis on next-generation characterization and analysis tools for the high-frequency electronics and communication market, and a leading electrical engineering products company serving students, universities and OEMs worldwide with technology based educational design tools. These acquisitions are expected to accelerate the deployment of our RF and wireless technologies, accelerate our expansion into digital and embedded education, gain access to fast turn, low cost development and manufacturing capabilities, and increase our position in semiconductor academic programs. The combined purchase price of the acquisitions was $42 million consisting of $25 million cash, net of $5 million cash received, and $12 million in future cash payments. We funded the cash portion of the purchase price from existing cash balances. The allocation of the purchase price was determined using the fair value of assets and liabilities acquired as of the respective closing dates. Our consolidated financial statements include the operating results from the dates of acquisition. Pro-forma results of operations have not been presented because the effects of those operations were not material. The finalization of our purchase price allocation during the fourth quarter of 2013 resulted in a net increase in tangible assets of $1.5 million, a decrease in intangible assets of $1,000 , and a decrease in goodwill of approximately $1.5 million.
