and $338.1 million, respectively. We believe these changes generally follow the pattern of the performance in the various end-markets served by our customers. During the quarter ended December
31, 2009, we prepared our annual goodwill impairment analyses. The estimated fair values of the Sensors, Electrical Protection, Power Protection and Interconnection reporting units used in those analyses exceeded their carrying values by 147.1%,
116.3%, 26.1% and 81.3%, respectively.
We did not
prepare updated interim goodwill impairment analyses as of December 31, 2009 for any reporting unit, as we believed, based on our financial performance during the fourth quarter of 2009, the financial forecasts and the improvement in the global
economy and the end-markets our customers serve, that there were no indicators of potential impairments.
Types of events that could result in a goodwill impairment. As noted above, the preparation of the long-range forecasts, the selection
of the discount rates and the estimation of the multiples or long-term growth rates used in valuing the Terminal Year involve significant judgments. Changes to these assumptions could affect the estimated fair value of our reporting units and could
result in a goodwill impairment charge in a future period. We believe that a double-dip in the global economy, a scenario in which there is a short period of growth following the bottom of a recession, followed immediately by another
sharp decline that results in another recession could require us to revise our long-term projections and could reduce the multiples applied to the Terminal Year value. Such revisions could result in a goodwill impairment charge in the future.
Indefinite-Lived Intangible Assets. We
perform an annual impairment review of our indefinite-lived intangible assets unless events occur which trigger the need for an earlier impairment review. The impairment review requires management to make assumptions about future conditions
impacting the value of the indefinite- lived intangible assets, including projected growth rates, cost of capital, effective tax rates, royalty rates, market share and other items.
Definite-Lived Intangible Assets. Reviews are regularly performed to determine whether facts or
circumstances exist that indicate the carrying values of our definite-lived intangible assets to be held and used are impaired. The recoverability of these assets is assessed by comparing the projected undiscounted net cash flows associated with
those assets to their respective carrying amounts. If the sum of the projected undiscounted net cash flows falls below the carrying value of the assets, the impairment charge is based on the excess of the carrying amount over the fair value of those
assets. Fair value is determined by using the appropriate income approach valuation methodology depending on the nature of the intangible asset.
Impairment of Long-Lived Assets. We periodically re-evaluate carrying values and estimated useful lives of long-lived assets whenever
events or changes in circumstances indicate that the carrying amount of the related assets may not be recoverable. We use estimates of undiscounted cash flows from long-lived assets to determine whether the book value of such assets is recoverable
over the assets remaining useful lives. These estimates include assumptions about future conditions within the Company and the industry. If an asset is determined to be impaired, the impairment is measured by the amount by which the carrying
value of the asset exceeds its fair value. These evaluations are performed at a level where discrete cash flows may be attributed to either an individual asset or a group of assets.
Inventories are stated at the lower of cost or estimated net realizable value. Cost for raw materials, work-in-process and finished goods is
determined on a first-in, first-out basis and includes material, labor and applicable manufacturing overhead as well as transportation and handling costs. We conduct quarterly inventory reviews for salability and obsolescence. Allowances are
determined by comparing inventory levels of individual materials and parts to historical usage rates, current backlog and estimated future sales and by analyzing the age of inventory, in order to identify specific components of inventory that are
judged unlikely to be sold. Provisions to the inventory allowance are recognized regularly based on the analysis described above and could have a material adverse impact on our financial condition and results of operations.
