Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill and Intangible Assets Disclosure [Text Block] | NOTE 6. GOODWILL AND OTHER INTANGIBLE ASSETS As discussed in Note 3, goodwill arises from the purchase price for acquired businesses exceeding the fair value of tangible and intangible assets acquired less assumed liabilities. We assess the goodwill of each of our reporting units for impairment at least annually as of the first day of the fourth quarter and as “triggering” events occur that indicate that it is more likely than not that an impairment exists. We elected to bypass the optional qualitative goodwill assessment allowed by applicable accounting standards and performed a quantitative impairment test for all reporting units as this was determined to be the most effective method to assess for impairment across a large spectrum of reporting units. We estimate the fair value of our reporting units primarily using a market approach, based on multiples of earnings before interest, taxes, depreciation and amortization (“EBITDA”) determined by current trading market multiples of earnings for companies operating in businesses similar to each of our reporting units, in addition to recent market available sale transactions of comparable businesses. In certain circumstances we also evaluate other factors including results of the estimated fair value utilizing a discounted cash flow analysis (i.e., an income approach), market positions of the businesses, comparability of market sales transactions and financial and operating performance in order to validate the results of the market approach. If the estimated fair value of the reporting unit is less than its carrying value, we must perform additional analysis to determine if the reporting unit’s goodwill has been impaired. In 2017, we had thirteen reporting units for goodwill impairment testing. The carrying value of the goodwill included in each individual reporting unit ranges from $7 million to approximately $1.1 billion. No goodwill impairment charges were recorded for the years ended December 31, 2017, 2016 and 2015 and no “triggering” events have occurred subsequent to the performance of the 2017 annual impairment test. The factors used by management in its impairment analysis are inherently subject to uncertainty. If actual results are not consistent with management’s estimates and assumptions, goodwill and other intangible assets may be overstated and a charge would need to be taken against net earnings. The following is a rollforward of our goodwill by segment ($ in millions):
| Professional Instrumentation |  | Industrial Technologies |  | Total
Balance, January 1, 2016 | $ | 2,400.6 |  |  | $ | 1,548.4 |  |  | $ | 3,949.0 |
Attributable to 2016 acquisitions | 61.3 |  |  | 51.9 |  |  | 113.2 |

Balance, December 31, 2016 | 2,423.7 |  |  | 1,555.3 |  |  | 3,979.0 |
Attributable to 2017 acquisitions | 851.8 |  |  | 183.4 |  |  | 1,035.2 |

Balance, December 31, 2017 | $ | 3,331.0 |  |  | $ | 1,767.5 |  |  | $ | 5,098.5 |
Finite-lived intangible assets are amortized over the shorter of their legal or estimated useful lives. The following summarizes the gross carrying value and accumulated amortization for each major category of intangible asset as of December 31 ($ in millions):
| 2017 |  | 2016
| Gross Carrying Amount |  | Accumulated Amortization |  | Gross Carrying Amount |  | Accumulated Amortization
Finite-lived intangibles: |  |  |  |  |  |  |
Patents and technology | $ | 376.6 |  |  | $ | (255.0 | ) |  | $ | 301.0 |  |  | $ | (240.1 | )
Customer relationships and other intangibles | 1,221.9 |  |  | (502.1 | ) |  | 734.9 |  |  | (438.1 | )
Total finite-lived intangibles | 1,598.5 |  |  | (757.1 | ) |  | 1,035.9 |  |  | (678.2 | )
Indefinite-lived intangibles: |  |  |  |  |  |  |
Trademarks and trade names | 434.6 |  |  | — |  |  | 389.6 |  |  | — |
Total intangibles | $ | 2,033.1 |  |  | $ | (757.1 | ) |  | $ | 1,425.5 |  |  | $ | (678.2 | )
During 2017 and 2016, we acquired finite-lived intangible assets, consisting primarily of customer relationships, with a weighted average life of 13 years and 14 years, respectively. Refer to Note 3 for additional information on the intangible assets acquired. Total intangible amortization expense in 2017, 2016 and 2015 was $65 million, $86 million and $89 million, respectively. Based on the intangible assets recorded as of December 31, 2017, amortization expense is estimated to be $97 million during 2018, $93 million during 2019, $88 million during 2020, $85 million during 2021 and $81 million during 2022.

- Definition The entire disclosure for the aggregate amount of goodwill and a description of intangible assets, which may include (a) for amortizable intangible assets (also referred to as finite-lived intangible assets), the carrying amount, the amount of any significant residual value, and the weighted-average amortization period, (b) for intangible assets not subject to amortization (also referred to as indefinite-lived intangible assets), the carrying amount, and (c) the amount of research and development assets acquired and written off in the period, including the line item in the income statement in which the amounts written off are aggregated, if not readily apparent from the income statement. Also discloses (a) for amortizable intangibles assets in total and by major class, the gross carrying amount and accumulated amortization, the total amortization expense for the period, and the estimated aggregate amortization expense for each of the five succeeding fiscal years, (b) for intangible assets not subject to amortization the carrying amount in total and by major class, and (c) for goodwill, in total and for each reportable segment, the changes in the carrying amount of goodwill during the period (including the aggregate amount of goodwill acquired, the aggregate amount of impairment losses recognized, and the amount of goodwill included in the gain (loss) on disposal of a reporting unit). If any part of goodwill has not been allocated to a reportable segment, discloses the unallocated amount and the reasons for not allocating. For each impairment loss recognized related to an intangible asset (excluding goodwill), discloses: (a) a description of the impaired intangible asset and the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method for determining fair value, (c) the caption in the income statement or the statement of activities in which the impairment loss is aggregated, and (d) the segment in which the impaired intangible asset is reported. For each goodwill impairment loss recognized, discloses: (a) a description of the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method of determining the fair value of the associated reporting unit, and (c) if a recognized impairment loss is an estimate not finalized and the reasons why the estimate is not final. May also disclose the nature and amount of any significant adjustments made to a previous estimate of an impairment loss. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 350 -SubTopic 30 -Section 50 -Paragraph 3 -URI http://asc.fasb.org/extlink&oid=66006027&loc=d3e16373-109275 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 350 -SubTopic 30 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=66006027&loc=d3e16265-109275 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 350 -SubTopic 30 -Section 50 -Paragraph 2 -URI http://asc.fasb.org/extlink&oid=66006027&loc=d3e16323-109275 Reference 4: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 350 -SubTopic 20 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=35741047&loc=d3e13816-109267 Reference 5: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 350 -SubTopic 20 -Section 50 -Paragraph 2 -URI http://asc.fasb.org/extlink&oid=35741047&loc=d3e13854-109267 + Details
