Entire Document

(dollars in thousands, except per share data)
Functional Currency and Exchange Rate Losses
The currency of the primary economic environment in which Tower, TJT and Jazz conduct their operations is the U.S. Dollar (“dollar”). Thus, the dollar is their functional and reporting currency. Accordingly, monetary accounts maintained in currencies other than the dollar are re-measured into dollars in accordance with ASC  830-10 “Foreign Currency Matters”. All transaction gains and losses from the re-measurement of monetary balance sheet items are reflected in the statements of operations as financial income or expenses, as appropriate. The financial statements of TPSCo, whose functional currency is the Japanese Yen (“JPY”), have been translated into dollars. The assets and liabilities have been translated using the exchange rate in effect as of the balance sheet date. The statement of operations of TPSCo has been translated using the average exchange rate for the reported period. The resulting translation adjustments are charged or credited to OCI.
Stock-Based Compensation
The Company applies the provisions of ASC Topic 718 “Compensation - Stock Compensation”, under which employees’ share-based equity awards are accounted for under the fair value method. Accordingly, stock-based compensation granted to employees and directors is measured at the grant date, based on the fair value of the grant. The Company uses the straight-line attribution method to recognize stock-based compensation costs over the vesting period of the grant, except for grants that involve performance criteria, for which an accelerated method is used.
Impairment of Assets

Impairment of Property, Equipment and Intangible Assets
The Company reviews long-lived assets and intangible assets on a periodic basis, as well as when such a review is required based upon relevant circumstances, to determine whether events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable, considering the undiscounted cash flows expected from it. If applicable, the Company recognizes an impairment loss based upon the difference between the carrying amount and the fair value of such assets, in accordance with ASC 360-10 “Property, Plant and Equipment”.

Impairment of Goodwill
Goodwill is subject to an impairment test performed at least on an annual basis or upon the occurrence of certain events or circumstances. The goodwill impairment test is performed based on the result of an initial qualitative assessment for the likelihood of impairment. If this assessment does not result in a more-likely-than-not indication of impairment, no further impairment testing is required. If it does result in a more-likely-than-not indication of impairment, the impairment test is performed.
