BASIS OF PRESENTATION The financial statements have been prepared in accordance with generally accepted accounting principles in the United States. USE OF ESTIMATES Use of these accounting principles required management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period. These estimates are reviewed periodically, and, as adjustments become necessary, they are reported in earnings in the period in which they become known. The financial statements reflect the following policies. REVENUE Revenue from the sale of products is recognized at the time of delivery when all requirements of a completed transaction have been met. INVENTORY Batteries and ancillary electronic products inventory is recorded at the lower of cost and net realizable value with cost being determined on the first-in, first-out basis. INCOME TAXES The Company accounts for income taxes in accordance with Statement of Financial Accounting Standards (SFAS) No. 109, Accounting for Income Taxes. Under SFAS No. 109, deferred tax assets and liabilities are determined based on temporary differences between the financial statement and tax bases of assets and liabilities and net operating loss and credit carryforwards using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized. A provision for income tax expense is recognized for income taxes payable for the current period, plus the net changes in deferred tax amounts. OTHER COMPREHENSIVE INCOME The Company does not have any other comprehensive income items. EARNINGS PER SHARE For the ten month period ended October 31, 2002, net income per share has been computed using the net income for the period divided by the weighted average number of shares outstanding. Diluted loss per share is not presented as the Company has no diluting items. <Page> DECADE BATTERY LTD.
