Finite-lived intangible assets are tested for impairment when facts or circumstances suggest that the carrying value of the asset may not be recoverable. If the carrying value exceeds the projected undiscounted pre-tax cash flows of the intangible asset, an impairment loss equal to the excess of the carrying value over the estimated fair value (discounted after-tax cash flows) is recognized. 

## Restructuring 

Restructuring charges are recognized as a result of actions to streamline operations and rationalize manufacturing facilities. Judgment is used when estimating the impact of restructuring plans, including future termination benefits and other exit costs to be incurred when the actions take place. Actual results could vary from these estimates. 

## Contingencies 

Loss contingencies from legal proceedings and claims may occur from a wide range of matters, including, government investigations, shareholder lawsuits, product and environmental liability, contractual claims and tax matters. Accruals are recognized when it is probable that a liability will be incurred and the amount of loss can be reasonably estimated. Gain contingencies are not recognized until realized. Legal fees are expensed as incurred. 

## Derivative Financial Instruments 

Derivatives are used principally in the management of interest rate and foreign currency exposures and are not held or used for trading purposes. 

Derivatives are recognized at fair value with changes in fair value recognized in earnings unless specific hedge criteria are met. If the derivative is designated as a fair value hedge, changes in fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. If the derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are reported in accumulated other comprehensive income (OCI) and subsequently recognized in earnings when the hedged item affects earnings. Cash flows are classified consistent with the underlying hedged item. 

Derivatives are designated and assigned as hedges of forecasted transactions, specific assets or specific liabilities. When hedged assets or liabilities are sold or extinguished or the forecasted transactions being hedged are no longer probable to occur, a gain or loss is immediately recognized in earnings. 

Non-derivative instruments, primarily euro denominated long-term debt, are also designated as hedges of net investments in foreign affiliates. The effective portion of the designated non-derivative instrument is recognized in the foreign currency translation section of OCI and the ineffective portion is recognized in earnings. 

## $^{ }$Shipping and Handling Costs 

$^{ }$Shipping and handling costs are included in marketing, selling and administrative expenses and were $125 million in 2012, $139 million in 2011 and $135 million in 2010. 

## $^{ }$Advertising and Product Promotion Costs 

$^{ }$Advertising and product promotion costs are expensed as incurred. 

## $^{ }$Foreign Currency Translation 

$^{ }$Foreign subsidiary earnings are translated into U.S. dollars using average exchange rates. The net assets of foreign subsidiaries are translated into U.S. dollars using current exchange rates. The U.S. dollar effects that arise from translating the net assets of these subsidiaries at changing rates are recognized in OCI. 

## $^{ }$Research and Development 

$^{ }$Research and development costs are expensed as incurred. Clinical study costs are accrued over the service periods specified in the contracts and adjusted as necessary based upon an ongoing review of the level of effort and costs actually incurred. Strategic alliances with third parties provide rights to develop, manufacture, market and/or sell pharmaceutical products, the rights to which are owned by the other party. Certain research and development payments to alliance partners are contingent upon the achievement of certain pre- determined criteria. Milestone payments achieved prior to regulatory approval of the product are expensed as research and development. Milestone payments made in connection with regulatory approvals are capitalized and amortized to cost of products sold over the remaining useful life of the asset. Capitalized milestone payments are tested for recoverability periodically or whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. Research and development is recognized net of reimbursements in connection with collaboration agreements.
