expected asset lives may be shortened or an impairment recorded based on a change in the expected use of the asset or performance of the related business reporting unit. 

 

3M goodwill totaled approximately $3.5 billion at December 31, 2005, which, based on impairment testing, is not impaired. Impairment testing for goodwill is done at a reporting unit level. Reporting units are one level below the business segment level, but can be combined when reporting units within the same segment have similar economic characteristics. 3M had 18 reporting units at December 31, 2005. The majority of goodwill relates to and is assigned directly to a specific reporting unit. An impairment loss generally would be recognized when the carrying amount of the reporting unit’s net assets exceeds the estimated fair value of the reporting unit. The estimated fair value of a reporting unit is determined using earnings for the reporting unit multiplied by a price/earnings ratio for comparable industry groups, or by using a discounted cash flow analysis.

 

NEW ACCOUNTING PRONOUNCEMENTS

As of December 31, 2005, the Company adopted FASB Interpretation No. 47, “Accounting for Conditional Asset Retirement Obligations” (FIN 47).  This accounting standard applies to the fair value of a liability for an asset retirement obligation associated with the retirement of tangible long-lived assets and where the liability can be reasonably estimated. Conditional asset retirement obligations exist for certain of the Company’s long-term assets. The fair value of these obligations is recorded as liabilities on a discounted basis. Over time the liabilities are accreted for the change in the present value and the initial capitalized costs are depreciated over the useful lives of the related assets.  The adoption of FIN 47 resulted in the recognition of an asset retirement obligation liability of $59 million and an after tax charge of $35 million, which is reflected as a cumulative change in accounting principle in the Consolidated Statement of Income. The pro forma effect of applying this guidance in all prior periods presented was determined not to be material.

 

Effective January 1, 2006, 3M adopted SFAS No. 123 (revised 2004), “Share-Based Payment”, which requires 3M to expense stock-based compensation expense. The Company is adopting SFAS No. 123R using the modified retrospective method. All prior periods will be adjusted to give effect to the fair-value-based method of accounting for awards granted in fiscal years beginning on or after January 1, 1995. Stock-based compensation disclosures in Note 1 reflect pro forma expense of $.14 cents per diluted share in 2005. The 2006 impact of adopting SFAS No. 123R is estimated to be approximately $.16 per diluted share with an estimated $0.02 per diluted share cost in the first quarter, an estimated $0.08 per diluted share cost in the second quarter, and an estimated $0.03 per diluted share cost in both the third and fourth quarters. The pro forma impact of stock-based compensation on net income and earnings per share provided in Note 1 for the years ended December 31, 2005, 2004 and 2003, was recognized over the nominal vesting
