Stockholders Equity Policy [Text Block]

Net unrealized currency gains or losses resulting from the translation of assets and liabilities of foreign subsidiaries, except those in highly inflationary economies, are recorded in AOCI. For these operations, changes in exchange rates generally do not affect cash flows; therefore, unrealized translation adjustments are recorded in AOCI rather than net income. Upon sale or substantially complete liquidation of any of these subsidiaries, the applicable unrealized translation adjustment would be removed from AOCI and reported as part of the gain or loss on the sale or liquidation. The change in unrealized translation is primarily due to a strengthening of the U.S. dollar versus most foreign currencies, partially offset by a weakening of the U.S. dollar against the Australian dollar.

Also included in unrealized translation amounts are the effects of foreign exchange rate changes on intercompany balances of a long-term investment nature and transactions designated as hedges of net foreign investments.
