A summary of the significant accounting policies used in preparing our financial statements are as follows:

• Special and non-recurring items generally represent revenues and gains as well as expenses and losses that are non-operational and/or non-recurring in nature. Several of these special and non-recurring items include impairment losses. These impairment losses were determined in accordance with our policy of comparing the fair value of the asset with its carrying value. The fair value is determined by quoted market prices or by estimates of future cash flows. There is inherent subjectivity involved in estimating future cash flows, which can have a significant impact on the amount of any impairment.
• Verizon’s plant, property and equipment balance represents a significant component of our consolidated assets. Depreciation expense on Verizon’s telephone operations is principally based on the composite group remaining life method and straight-line composite rates, which provides for the recognition of the cost of the remaining net investment in telephone plant, less anticipated net salvage value, over the remaining asset lives. We depreciate other plant, property and equipment generally on a straight-line basis over the estimated useful life of the assets. Changes in the remaining useful lives of assets as a result of technological change or other changes in circumstances, including competitive factors in the markets where we operate, can have a significant impact on asset balances and depreciation expense.
• We maintain benefit plans for most of our employees, including pension and other postretirement benefit plans. In the aggregate, the fair value of pension plan assets exceeds benefit obligations, which contributes to pension plan income. Other postretirement benefit plans have larger benefit obligations than plan assets, resulting in expense. Significant benefit plan assumptions, including the discount rate used, the long-term rate of return on plan assets and heath care trend rates are periodically updated and impact the amount of benefit plan income, expense, assets and obligations (see “Consolidated Results of Operations – Consolidated Operating Expenses – Pension and Other Postretirement Benefits”). A sensitivity analysis of the impact of changes in these assumptions on the benefit obligations and expense (income) recorded as of December 31, 2005 and for the year then ended pertaining to Verizon’s pension and postretirement benefit plans is provided in the tables below. Note that some of these sensitivities are not symmetrical as the calculations were based on all of the actuarial assumptions as of year-end.
