The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) and on the same basis as the audited financial statements included in our annual report on Form 10-K for the year ended December 31, 2018, except for the effects of adopting Accounting Standards Update (ASU) No. 2016-02, Leases (Topic 842). The Consolidated Statements of Income, Comprehensive Income and Cash Flows for the periods ended March 31, 2019 and 2018, and the Consolidated Balance Sheet as of March 31, 2019, are not audited but reflect all adjustments that are of a normal recurring nature and are necessary for a fair statement of the results of the periods shown. Certain information and note disclosures normally included in annual consolidated financial statements have been omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Because the consolidated interim financial statements do not include all of the information and notes required by GAAP for a complete set of financial statements, they should be read in conjunction with the audited consolidated financial statements and notes included in our annual report on Form 10-K for the year ended December 31, 2018. The results for the three-month periods are not necessarily indicative of a full year’s results.

We determine if an arrangement is a lease at inception. Leases are included in other long-term assets, accrued expenses and other liabilities, and other long-term liabilities on our Consolidated Balance Sheets.

Lease assets represent our right to use underlying assets for the lease term, and lease liabilities represent our obligations to make lease payments over the lease term. On the commencement date, leases are evaluated for classification, and assets and liabilities are recognized based on the present value of lease payments over the lease term. We use our incremental borrowing rate based on the information available at commencement in determining the present value of lease payments. Operating lease expense is generally recognized on a straight-line basis over the lease term. Our lease values include options to extend or not to terminate the lease when it is reasonably certain that we will exercise such options.

We have agreements with lease and non-lease components, which are accounted for as a single lease component. Leases with a lease term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term.

We use the two-class method for calculating EPS because the restricted stock units (RSUs) we grant are participating securities containing non-forfeitable rights to receive dividend equivalents. Under the two-class method, a portion of net income is allocated to RSUs and excluded from the calculation of income allocated to common stock, as shown in the table below.

Computation and reconciliation of earnings per common share are as follows (shares in millions):

	For Three Months Ended March 31,
	2019							2018
	Net							Net
	Income			Shares		EPS		Income			Shares		EPS
Basic EPS:
Net income	$	1,217						$	1,366
Income allocated to RSUs		(8	)						(11	)
Income allocated to common stock	$	1,209			939	$	1.29	$	1,355			983	$	1.38
Dilutive effect of stock compensation plans					17							22

Diluted EPS:
Net income	$	1,217						$	1,366
Income allocated to RSUs		(8	)						(11	)
Income allocated to common stock	$	1,209			956	$	1.26	$	1,355			1,005	$	1.35

Potentially dilutive securities representing 9 million and 5 million shares of common stock that were outstanding during the first quarters of 2019 and 2018, respectively, were excluded from the computation of diluted earnings per common share during these periods because their effect would have been anti-dilutive.

We use derivative financial instruments to manage exposure to foreign exchange risk. These instruments are primarily forward foreign currency exchange contracts, which are used as economic hedges to reduce the earnings impact that exchange rate fluctuations may have on our non-U.S. dollar net balance sheet exposures. Gains and losses from changes in the fair value of these forward foreign currency exchange contracts are credited or charged to OI&E. We do not apply hedge accounting to our foreign currency derivative instruments.

In connection with the issuance of long-term debt, we may use financial derivatives such as treasury-rate lock agreements that are recognized in AOCI and amortized over the life of the related debt. The results of these derivative transactions have not been material.

The fair values of our derivative financial instruments were not material as of March 31, 2019. Our investments in cash equivalents, short-term investments and certain long-term investments, as well as our deferred compensation liabilities, are carried at fair value. The carrying values for other current financial assets and liabilities, such as accounts receivable and accounts payable, approximate fair value due to the short maturity of such instruments. The carrying value of our long-term debt approximates the fair value as measured using broker-dealer quotes, which are Level 2 inputs. See Note 4 for a description of fair value and the definition of Level 2 inputs.

We adopted ASU No. 2016-02, Leases (ASC 842) effective January 1, 2019, using the modified retrospective transition method applied to leases existing at, or entered into after, the adoption date. The reported results for 2019 reflect the application of the new accounting guidance, while the reported results for prior periods are not adjusted and continue to be reported in accordance with our historical accounting under ASC 840, Leases. In addition, we elected the package of practical expedients permitted under the transition guidance that allowed us to apply prior conclusions related to lease definition, classification and initial direct costs.

The adoption of the new standard resulted in the recognition of $229 million of lease liabilities with corresponding lease assets as of January 1, 2019. The standard did not materially impact our consolidated results of operations and had no impact on cash flows.

ASU	Description	Adopted Date
ASU No. 2017-12	Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities	January 1, 2019

Changes in accounting standards – standards not yet adopted

ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments

This standard requires entities to use a current lifetime expected credit loss methodology to measure impairments of certain financial assets. Using this methodology will result in earlier recognition of losses than under the current incurred loss approach, which requires waiting to recognize a loss until it is probable of having been incurred. There are other provisions within the standard that affect how impairments of other financial assets may be recorded and presented, and that expand disclosures. This standard will be effective for our interim and annual periods beginning January 1, 2020, with early adoption permitted beginning January 1, 2019, and must be applied on a modified retrospective basis. We are currently evaluating the potential impact of this standard, but we do not expect it to have a material impact on our financial position and results of operations.

Other standards

We are evaluating the impact of the following standards, but we do not expect them to have a material impact on our financial position and results of operations. We plan to adopt these standards as of their effective dates.

ASU	Description	Effective Date
