BASIS OF PRESENTATION Telinnovation (the "Company"), as presented in these financial statements, is the combination of three entities, Telinnovation (a partnership), Telinnovation Corporation (an S-corporation), and Telinnovation Service Corporation (an S-corporation), which are all under common control. Effective February 1, 2000, Ditech Communications Corporation acquired from the Company the operating assets relating to an echo cancellation business. Historically, combined financial statements were not prepared for the three Telinnovation entities. The accompanying statements were prepared to comply with the rules and regulations of the Securities and Exchange Commission. These financial statements are derived from the three Telinnovation entities historical accounting records and intercompany transactions and balances have been eliminated. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. REVENUE RECOGNITION The Company derives the significant portion of its revenue from the licensing of echo cancellation technology. Customers pay royalties to the Company for each unit they sell which employs the Company's technology. Revenue is recorded by the Company as notified by the licensee. INCOME TAXES There is no provision for income taxes in the financial statements of the Company. Each partner or shareholder is individually liable for their own tax payments on their share of the income of the Company. RESEARCH AND DEVELOPMENT Research and development costs are expensed as incurred. CONCENTRATION OF CREDIT RISK Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, investments and accounts receivable. The Company's accounts receivable are derived from revenue earned from customers located in the U.S., Canada, France, China, Germany, Belgium, Italy and Israel. The Company performs ongoing credit evaluations of its customers' financial condition and, generally, requires no collateral from its customers. During the year ended December 31, 1998, three customers accounted for 93% (52%, 30% and 11%, respectively) of net revenues. During the ten months ended October 31, 1999, two customers accounted for 95% (89% and 6%) of net revenues. At December 31, 1998, three customers accounted for 36%, 29% and 26% of total accounts receivable, respectively. At October 31, 1999, no customer accounted for greater than 10% of total accounts receivable. PROPERTY AND EQUIPMENT Property and equipment are stated at cost and are depreciated using the straight line method over their estimated useful lives ranging from three to five years. 11 TELINNOVATION NOTES TO FINANCIAL STATEMENTS (CONTINUED) TEN MONTHS ENDED OCTOBER 31, 1999 AND YEAR ENDED DECEMBER 31, 1998 CASH AND CASH EQUIVALENTS The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Management believes that the financial institutions in which it maintains such deposits are financially sound and, accordingly, minimal credit risk exists with respect to these deposits. Cash and cash equivalents are held by two major U.S. financial institutions. FAIR VALUE OF FINANCIAL INSTRUMENTS Carrying amounts of certain of the Company's financial instruments, including cash and cash equivalents, accounts receivable and accounts payable are considered to approximate fair value because of their short maturities. The fair value of investments are determined using quoted market prices for those securities or similar financial instruments (see Note 4). LONG-LIVED ASSETS The Company periodically evaluates the recoverability of its long-lived assets based upon expected undiscounted cash flows and recognizes impairment from the carrying value of long-lived assets, if any, based on the fair value such assets. INTANGIBLE ASSETS Intangible assets comprise of patents. Intangible assets are amortized on a straight-line basis over the estimated lives, which is 15 years. COMPREHENSIVE INCOME In fiscal 1999, the Company adopted Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive Income" ("FAS 130"). FAS 130 establishes standards for reporting and display of comprehensive income and its components in a full set of general-purpose financial statements. In the Company's case, other comprehensive income comprises unrealized gains on available for sale investments. NEW ACCOUNTING PRONOUNCEMENT In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." SFAS No. 133 establishes methods of accounting for derivative financial instruments and hedging activities related to those instruments as well as other hedging activities. The Company has not yet determined what the effect of SFAS No. 133 will be on the operations and financial position of the Company. The Company will be required to implement SFAS No. 133 beginning in 2001. 12 3.
