Accounting Changes and Error Corrections [Abstract]
New accounting pronouncements	Note 2. New accounting pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09 “Revenue from Contracts with Customers.” ASU 2014-09 applies to contracts with customers, excluding, most notably, insurance and leasing contracts. The framework prescribed by ASU 2014-09 includes (a) identifying the contract, (b) identifying the related performance obligations, (c) determining the transaction price, (d) allocating the transaction price to the identified performance obligations and (e) recognizing revenues as the identified performance obligations are satisfied. Based on our evaluations, we do not currently believe the adoption of ASU 2014-09 will have a material effect on our Consolidated Financial Statements. However, the timing of the recognition of revenue and related costs may change with respect to certain of our contracts with customers. For instance, revenues and costs for certain contracts may be recognized over time rather than when the product or service is delivered, as is the current practice. In addition, certain contracts may be treated as leases for accounting purposes, rather than contracts with customers subject to ASU 2014-09. Our evaluations of these and other issues and implementation efforts concerning ASU 2014-09 are ongoing and also include consideration of the new disclosure requirements. We will adopt ASU 2014-09 as of January 1, 2018, under the modified retrospective method. In January 2016, the FASB issued ASU 2016-01 “Financial Instruments—Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 generally requires that investments in equity securities (excluding equity method investments) be measured at fair value with changes in fair value recognized in net earnings. Under existing GAAP, changes in fair value of available-for-sale equity securities are recorded in other comprehensive income. Given the current magnitude of our investments in equity securities, the adoption of ASU 2016-01 will have a significant impact on the periodic net earnings reported in our Consolidated Statement of Earnings, although it will not affect our comprehensive income or total shareholders’ equity. We will adopt ASU 2016-01 as of January 1, 2018. As of that date, the accumulated net unrealized appreciation relating to our investments in equity securities, which is currently included in accumulated other comprehensive income, will be reclassified to retained earnings. In February 2016, the FASB issued ASU 2016-02 “Leases.” ASU 2016-02 requires a lessee to recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term and also requires additional qualitative and quantitative disclosures. ASU 2016-02 is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the effect this standard will have on our Consolidated Financial Statements. In June 2016, the FASB issued ASU 2016-13 “Financial Instruments—Credit Losses,” which provides for the recognition and measurement at the reporting date of all expected credit losses for financial assets held at amortized cost and available-for-sale debt securities. Currently, credit losses are recognized and measured when such losses become probable based on the prevailing facts and circumstances. ASU 2016-13 is effective for reporting periods beginning after December 15, 2019. We are currently evaluating the effect this standard will have on our Consolidated Financial Statements. In January 2017, the FASB issued ASU 2017-04 “Simplifying the Test for Goodwill Impairment.” ASU 2017-04 eliminates the requirement to determine the implied value of goodwill in measuring an impairment loss. Upon adoption, the measurement of a goodwill impairment will represent the excess of the reporting unit’s carrying value over fair value, limited to the carrying value of goodwill. ASU 2017-04 is effective for goodwill impairment tests in fiscal years beginning after December 15, 2019, with early adoption permitted.
