## Shipping and Handling Costs 

## Notes to Consolidated Financial Statements — (Continued) Becton, Dickinson and Company 

The Company considers its shipping and handling costs to be contract fulfillment costs and records them within Selling and administrative expense. Shipping expense was $551 million, $511 million and $479 million in 2020, 2019 and 2018, respectively. 

## Derivative Financial Instruments 

All derivatives are recorded in the balance sheet at fair value and changes in fair value are recognized currently in earnings unless specific hedge accounting criteria are met. Any deferred gains or losses associated with derivative instruments are recognized in income in the period in which the underlying hedged transaction is recognized. Additional disclosures regarding the Company's accounting for derivative instruments are provided in Note 14. 

## Income Taxes 

The Company has reviewed its needs in the United States for possible repatriation of undistributed earnings of its foreign subsidiaries and continues to invest foreign subsidiaries earnings outside of the United States to fund foreign investments or meet foreign working capital and property, plant and equipment expenditure needs. As a result, the Company is permanently reinvested with respect to all of its historical foreign earnings as of September 30, 2020. Deferred taxes are not provided on undistributed earnings of foreign subsidiaries that are indefinitely reinvested. The determination of the amount of the unrecognized deferred tax liability related to the undistributed earnings is not practicable because of the complexities associated with its hypothetical calculation. 

The Company conducts business and files tax returns in numerous countries and currently has tax audits in progress in a number of tax jurisdictions. In evaluating the exposure associated with various tax filing positions, the Company records accruals for uncertain tax positions based on the technical support for the positions, past audit experience with similar situations, and the potential interest and penalties related to the matters. 

The Company maintains valuation allowances where it is more likely than not that all or a portion of a deferred tax asset will not be realized. Changes in valuation allowances are included in the tax provision in the period of change. In determining whether a valuation allowance is warranted, management evaluates factors such as prior earnings history, expected future earnings, carryback and carryforward periods and tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset. Additional disclosures regarding the Company's accounting for income taxes are provided in Note 17. 

## Earnings per Share 

Basic earnings per share are computed by dividing income available to common stockholders by the weighted average number of common shares outstanding. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. In computing diluted earnings per share, only potential common shares that are dilutive (i.e., those that reduce earnings per share or increase loss per share) are included in the calculation. 

## Use of Estimates 

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. These estimates or assumptions affect reported assets, liabilities, revenues and expenses as reflected in the consolidated financial statements. Actual results could differ from these estimates.
