J-Devices Corporation

In October 2009, Amkor and Toshiba Corporation (“Toshiba”) invested in Nakaya Microdevices Corporation (“NMD”) and formed a joint venture to provide semiconductor packaging and test services in Japan. As a result of the transaction, NMD changed its name to J-Devices Corporation. We invested $16.7 million for our original 30% equity interest and options to acquire additional equity interests. In April 2013, we completed the exercise of our option to increase our ownership interest in J-Devices from 30% to 60% for an aggregate purchase price of $67.4 million. J-Devices is owned 60% by Amkor, 34% by the former shareholders of NMD and 6% by Toshiba.
At March 31, 2014, our investment includes our 60% equity interest and options to acquire additional equity interests. The remaining options are exercisable at our discretion and permit us to increase our ownership interest in J-Devices up to 66% in 2014 by purchasing shares owned by Toshiba and up to 80% in 2015 and thereafter by purchasing shares owned by the other shareholders. In 2014 and beyond, Toshiba has the option, at its discretion, to sell shares it owns to us. If we decline Toshiba's offer to sell its shares to us, then J-Devices shall have the obligation to purchase the shares. If J-Devices is unable to fulfill its obligation to purchase the shares offered by Toshiba, then we will be obligated to purchase the shares offered by Toshiba. The options in 2014 and 2015 become exercisable in the fourth quarter of such year, and if exercised, we would expect closing to occur in the first half of the following year, subject to regulatory approval. After we own 80% or more shares, the original shareholders of NMD have a put option which allows them to sell their shares to us. The exercise price for all options is payable in cash and is determined using a formula based upon the net book value and a multiple of earnings before interest, taxes, depreciation and amortization of J-Devices.

The governance provisions currently applicable to J-Devices restrict our ability, even with our majority ownership, to cause J-Devices to take certain actions without the consent of the other investors. Accordingly, we account for our investment in J-Devices using the equity method of accounting. Under the equity method of accounting, we recognize our proportionate share of J-Devices' net income or loss, which is after J-Devices' income taxes in Japan, during each accounting period as a change in our investment in unconsolidated affiliate. J-Devices' financial information is converted to U.S. GAAP and translated into U.S. dollars using Japanese yen as the functional currency. In addition, we record equity method adjustments as a change in our investment. The equity method adjustments include the amortization of basis differences as a result of the cost of our investment differing from our proportionate share of J-Devices' equity.
