3. Business Acquisitions

On July 31, 2013, we completed the purchase of 100% of the shares of Toshiba Electronics Malaysia Sdn. Bhd., Toshiba’s power discrete semiconductor packaging and test operation in Malaysia, and subsequently changed the name of the entity to Amkor Technology Malaysia Sdn. Bhd. The total price for the shares was approximately ¥6 billion ($60 million), based on the estimated net asset value at closing. The price for the shares is subject to adjustment to the extent the actual net asset value at closing was more or less than the estimate. We paid ¥4.1 billion ($42 million) in cash at closing and are obligated to pay the remaining ¥1.9 billion ($18 million) by March 31, 2014. We were also granted a non-exclusive, royalty bearing license by Toshiba to certain intellectual property rights for providing packaging and test services for power discrete and certain other semiconductor products. The license has a royalty cap of ¥1.5 billion. Under the purchase method of accounting, we allocated the purchase price to the assets acquired and liabilities assumed based on their estimated fair values on the date of acquisition. We did not record any goodwill as a result of the acquisition.
