Note 1 Description of Business, Separation, Basis of Presentation and Significant Accounting Policies

Description of the Business. Teradata Corporation ("Teradata" or "the Company") provides data warehousing solutions for customers worldwide that combine software (including the Teradata database and tools, data mining and analytical applications), hardware and related consulting and support services.

The Separation. On August 27, 2007, the Board of Directors of NCR Corporation ("NCR"), the Company's former parent, approved the separation of NCR into two independent, publicly traded companies through the distribution of 100% of its Teradata data warehousing business to shareholders of NCR (the "Separation").

To effect the Separation, Teradata Corporation, a Delaware corporation, was formed on March 27, 2007, as a wholly-owned subsidiary of NCR. Immediately prior to the Separation, the assets and liabilities of the Teradata data warehousing business of NCR were transferred to Teradata Corporation in return for 180.7 million shares of Teradata Corporation common shares. NCR accomplished the Separation through a distribution of one share of Teradata Corporation common stock for each share of NCR common stock on September 30, 2007, to NCR shareholders of record as of September 14, 2007.

During the year ended December 31, 2008, the Company recorded Separation-related adjustments of $25 million and $2 million to additional paid-in capital and other comprehensive income, respectively. These adjustments were primarily made to reflect certain deferred tax assets that were not initially recorded at the Separation. These adjustments had no impact on net income or cash flows for any periods presented.

Basis of Presentation. The financial statements are presented on a consolidated basis and include the accounts of the Company and its wholly-owned subsidiaries in accordance with accounting principles generally accepted in the United States of America ("GAAP").

Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the period reported. On an ongoing basis, management evaluates these estimates and judgments, including those related to allowances for doubtful accounts, the valuation of inventory to net realizable value, share-based compensation and income taxes and any changes will be accounted for on a prospective basis. Actual results could differ from those estimates.

Revenue Recognition. Teradata's solution offerings typically include software, software subscriptions, hardware, maintenance support services, and other consulting, implementation and installation-related ("consulting") services. Teradata records revenue when it is realized, or realizable, and earned. Teradata considers these requirements met when: (a) persuasive evidence of an arrangement exists; (b) the products or services have been delivered to the customer; (c) the sales price is fixed or determinable and free of contingencies or significant uncertainties; and (d) collectibility is reasonably assured. Teradata reports revenue net of any taxes assessed by governmental authorities that are imposed on and concurrent with specific revenue-producing transactions. Teradata delivers its solutions primarily through direct sales channels, as well as through alliances with system integrators, other independent software vendors and distributors, and value-added resellers (collectively referred to as "resellers"). In assessing whether the sales price to a reseller is fixed or determinable, the Company considers, among other things, past business practices with the reseller, the reseller's operating history, payment terms, return rights and the financial wherewithal of the reseller. When Teradata determines that the contract fee to a reseller is not fixed or determinable, that transaction is accounted for upon sell-through to the end customer.

Substantially all of Teradata's solutions contain software that is more than incidental to the hardware and services. The typical solution requires no significant production, modification or customization of the software or hardware, and the software is not essential to the functionality of the hardware. Therefore, hardware and related services are considered non-software deliverables. For software and software-related deliverables, Teradata allocates revenue to each software deliverable based upon its fair value as determined by vendor-specific objective evidence ("VSOE") using the residual method as discussed below. VSOE of fair value is based upon the normal pricing and discounting practices for those products and services when sold separately. For non-software related deliverables, fair value is based upon Verifiable Objective Evidence ("VOE"). VOE is based on the price when similar products or services are sold separately by Teradata or other companies. These elements often involve delivery or performance at different periods of time. Revenue for software is generally recognized upon delivery with the hardware using the residual method described below. Revenue for software subscriptions, which provide for unspecified upgrades or enhancements on a when-and-if-available basis, is recognized straight-line over the term of the subscription arrangement. Revenue for maintenance support services is also recognized on a straight-line basis over the term of the contract. Revenue for other consulting, implementation and installation services is recognized as services are provided. In certain instances, customer acceptance is required prior to the passage of title and risk of loss of the delivered products. In such cases, no revenue is recognized until the customer acceptance is obtained. Delivery and acceptance generally occur in the same reporting period.

For arrangements involving multiple deliverables, where the deliverables include software and non-software products and services, Teradata evaluates each deliverable to determine whether it represents a separate unit of accounting based on the following criteria: (a) whether the delivered item has value to the customer on a stand-alone basis; (b) whether there is objective and reliable evidence of the fair value of the undelivered items; and (c) if the contract includes a general right of return relative to the delivered item, delivery or performance of the undelivered items is considered probable and substantially in the control of Teradata. If objective and reliable evidence of fair value exists for all units of accounting in the arrangement, revenue is allocated to each unit of accounting based on relative fair values. Each unit of accounting is then accounted for under the applicable revenue recognition guidance. In situations where there is objective and reliable evidence of fair value for all undelivered elements, but not for delivered elements, the residual method is used to allocate the arrangement's consideration. Teradata does not typically have VSOE of fair value for software products. Therefore, in a substantial majority of Teradata arrangements, the residual method is used to allocate arrangement consideration. Under the residual method, the fair value of the undelivered elements is deferred and accounted for under the applicable revenue recognition guidance, and the remaining portion of the arrangement fee is allocated to the delivered elements and is recognized as revenue.

Teradata uses the stated renewal rate approach in establishing VSOE of fair value for maintenance and subscriptions. Under this approach, the Company assesses whether the contractually stated renewal rates are substantive and in line with the Company's normal pricing practices. Renewal rates greater than the lower level of our targeted pricing ranges are considered to be substantive and, therefore, meet the requirements to support VSOE. In instances where there is not a substantive renewal rate in the arrangement, the Company reallocates revenue from the delivered elements to increase the allocation of revenue for undelivered elements to the minimum established pricing targets as supported by the renewal rates for similar customers.

Teradata also offers consulting and installation-related services to its customers, which are considered software-related. These services are rarely considered essential to the functionality of the enterprise data warehouse ("EDW") solution deliverable and there is never any software customization of the proprietary database software. VSOE of fair value for consulting services is based on the hourly rates for standalone consulting services projects by geographic region and are indicative of our customary pricing practices. Pricing in each market is structured to obtain a reasonable margin based on input costs.

Shipping and Handling. Product shipping and handling costs are included in cost of products in the Consolidated Statements of Income.

Cash and Cash Equivalents. All short-term, highly-liquid investments having original maturities of three months or less are considered to be cash equivalents.

Allowance for Doubtful Accounts. Teradata establishes provisions for doubtful accounts using both percentages of accounts receivable balances to reflect historical average credit losses and specific provisions for known issues.

Inventories. Inventories are stated at the lower of cost or market, using the average cost method.

Long-Lived Assets

Property and Equipment. Property and equipment, leasehold improvements and rental equipment are stated at cost less accumulated depreciation. Depreciation is computed over the estimated useful lives of the related assets primarily on a straight-line basis. Equipment is depreciated over 3 to 20 years and buildings over 25 to 45 years. Leasehold improvements are depreciated over the life of the lease or the asset, whichever is shorter. Total depreciation expense on the Company's property and equipment for the years ended December 31, 2010, 2009 and 2008 was $25 million, $22 million and $24 million, respectively.

Capitalized Software. Direct development costs associated with internal-use software are capitalized and amortized over the estimated useful lives of the resulting software. The costs are capitalized when both the preliminary project stage is completed and it is probable that computer software being developed will be completed and placed in service. Teradata typically amortizes capitalized internal-use software on a straight-line basis over three years beginning when the asset is substantially ready for use.

Costs incurred for the development of software that will be sold, leased or otherwise marketed are capitalized when technological feasibility has been established. Technological feasibility is established when planning, designing and initial coding activities that are necessary to establish the product can be produced to meet its design specifications. In the absence of a program design, a working model is used to establish technological feasibility. These costs are included within capitalized software and are amortized over the estimated useful lives of the resulting software. The Company amortizes capitalized software over periods up to four years using the greater of the ratio that current gross revenues for a product bear to the total of current and anticipated future gross revenues for that product or the straight-line method over the remaining estimated economic life of the product beginning when the product is available for general release. Costs capitalized include direct labor and related overhead costs. Costs incurred prior to technological feasibility and after general release are expensed as incurred. The following table identifies the activity relating to capitalized software:

Valuation of Long-Lived Assets. Long-lived assets such as property and equipment and capitalized software are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. An impairment loss would be recognized when estimated future undiscounted cash flows expected to result from the use of the asset and its eventual disposition are less than the carrying amount.

Goodwill. Goodwill represents the excess of the purchase price in a business combination over the fair value of net tangible and intangible assets acquired. Goodwill amounts are not amortized, but rather are tested for impairment annually or if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company did not recognize any goodwill impairment charges in 2010, 2009 or 2008.

Warranty. Provisions for product warranties are recorded in the period in which the related revenue is recognized. The Company accrues warranty reserves using percentages of revenue to reflect the Company's historical average warranty claims.

Research and Development Costs. Research and development costs are expensed as incurred (with the exception of the capitalized software development costs discussed above). Research and development costs primarily include payroll and headcount-related costs, contractor fees, facilities costs, infrastructure costs, and administrative expenses directly related to research and development support.

Pension and Postemployment Benefits. The Company accounts for its pension and postemployment benefit obligations using actuarial models. The measurement of plan obligations was made as of December 31, 2010. Liabilities are computed using the projected unit credit method. The objective under this method is to expense each participant's benefits under the plan as they accrue, taking into consideration salary increases and the plan's benefit allocation formula. Thus, the total pension or postemployment benefit to which each participant is expected to become entitled is broken down into units, each associated with a year of past or future credited service.

The Company recognizes the funded status of its pension and postemployment plan obligations in its consolidated balance sheet and records in other comprehensive income certain gains and losses that arise during the period, but are deferred under pension accounting rules.

Foreign Currency. Assets and liabilities of non-U.S. subsidiaries that operate in a local currency environment are translated into U.S. dollars at period-end exchange rates. Income and expense accounts are translated at average exchange rates prevailing during the period. Adjustments arising from the translation are included in accumulated other comprehensive income (loss), a separate component of stockholders' equity. Gains and losses resulting from foreign currency transactions are included in determining net income.

Income Taxes. Income tax expense is provided based on income before income taxes in the various jurisdictions in which the Company conducts its business. Deferred income taxes reflect the impact of temporary differences between assets and liabilities recognized for financial reporting purposes and such amounts recognized for tax purposes. These deferred taxes are determined based on the enacted tax rates expected to apply in the periods in which the deferred assets or liabilities are expected to be settled or realized. Teradata recognizes tax benefits from uncertain tax positions only if it is more likely than not the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. The Company records valuation allowances related to its deferred income tax assets when it is more likely than not that some portion or all of the deferred income tax assets will not be realized.

Share-based Compensation. Share-based payments to employees, including grants of stock options, are recognized in the financial statements based on their fair value. The fair value of each stock option award on the grant date is estimated using the Black-Scholes option-pricing model with the following assumptions: expected dividend yield, expected stock price volatility, weighted-average risk-free interest rate and weighted average expected term of the options. The Company's expected volatility assumption used in the Black-Scholes option-pricing model is based on peer group volatility. The expected term assumption is based on the simplified method under GAAP, which is based on the vesting period and contractual term for each vesting tranche of awards. The mid-point between the vesting date and the expiration date is used as the expected term under this method. The risk-free interest rate used in the Black-Scholes model is based on the implied yield curve available on U.S. Treasury zero-coupon issues at the date of grant with a remaining term equal to the Company's expected term assumption. The Company has never declared or paid a cash dividend.

Treasury Stock. Prior to the second quarter of 2008, stock repurchased through the share repurchase programs was retired. Beginning in the second quarter of 2008, stock repurchased through the share repurchase programs was held as treasury stock. Treasury stock is accounted for using the cost method.

Earnings Per Share. Basic earnings per share is calculated by dividing net income by the weighted-average number of shares outstanding during the reported period. The calculation of diluted earnings per share is similar to basic earnings per share, except that the weighted-average number of shares outstanding includes the dilution from potential shares added from stock options, restricted stock awards and other stock awards. Refer to Note 5 for share information on the Company's stock compensation plans.

The components of basic and diluted earnings per share are as follows:

Options to purchase 0.6 million shares of common stock for 2010, 1.8 million shares of common stock for 2009 and 1.7 million shares of common stock for 2008 were not included in the computation of diluted earnings per share because their exercise prices were greater than the average market price of the common shares and, therefore, the effect would have been anti-dilutive.

Recently Issued Accounting Pronouncements

Multiple-Deliverable Revenue Arrangements. In October 2009, the Financial Accounting Standards Board ("FASB") issued new guidance regarding the accounting for revenue arrangements with multiple deliverables. This new guidance provides principles for allocation of consideration among its multiple-elements, allowing more alternatives in identifying and accounting for separate deliverables under an arrangement. The guidance will eliminate the residual method of allocation and require use of the relative selling price method. The guidance also introduces the best estimate selling price ("BESP") for valuing the deliverables of a bundled arrangement if vendor specific objective evidence ("VSOE") or third-party evidence of selling price is not available, and significantly expands related disclosure requirements. This guidance is effective on a prospective basis for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. Alternatively, adoption may be on a retrospective basis, and early application is permitted. The Company will adopt this guidance, on a prospective basis, for applicable transactions originating or materially modified on or after January 1, 2011. The Company is currently evaluating the impact of adopting this standard, but does not expect it to have a material impact on reported revenues.

Certain Revenue Arrangements That Include Software Elements. In October 2009, the FASB issued new guidance for revenue arrangements that include software elements. This new guidance changes the accounting model for revenue arrangements that include both tangible products and software elements. Tangible products containing software and nonsoftware elements that function together to deliver the tangible product's essential functionality will no longer be within the scope of software revenue guidance. The new guidance is effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010, and early application is permitted. The Company will adopt this guidance, on a prospective basis, for applicable transactions originating or materially modified on or after January 1, 2011. The Company is currently evaluating the impact of adopting this standard, but does not expect it to have a material impact on reported revenues.

Fair Value Measurements. In January 2010, the FASB issued an update to provide new disclosures, and clarifications of existing disclosures related to fair value measurements. The new disclosures will require reporting entities to disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and describe the reasons for the transfers. Additionally, in the Level 3 reconciliations, a reporting entity should present separately information about purchases, sales, issuances, and settlements. The update also clarifies that a reporting entity needs to use judgment in determining the appropriate classes of assets and liabilities, and should provide disclosures about the valuation techniques and inputs used to measure fair value for both recurring and nonrecurring fair value measurements in Level 2 and Level 3. The new disclosures and clarifications of existing disclosures are effective for interim and annual reporting periods beginning after December 15, 2009, except for the disclosures about purchases, sales, issuances, and settlements in the rollforward of activity in Level 3 fair value measurements. Those disclosures are effective for fiscal years beginning after December 15, 2010, and for interim periods within those fiscal years.

Note 3 Goodwill and Other Intangible Assets

The following table identifies the activity relating to goodwill by operating segment:

The change in goodwill for the twelve months ended December 31, 2010 was primarily due to an immaterial acquisition consummated during 2010, as well as changes in foreign currency exchange rates. The only change in goodwill for the twelve months ended December 31, 2009 was due to immaterial fluctuations in foreign currency exchange rates. In the fourth quarter of 2010, the Company performed its annual test of goodwill impairment and determined that no impairment to the carrying value of goodwill was necessary, as the fair value of each reporting segment was significantly in excess of their respective carrying amounts, including goodwill.

The Company's identifiable intangible assets, reported under Other Assets in the balance sheets, were specifically identified when acquired, and are deemed to have finite lives. The gross carrying amount and accumulated amortization for Teradata's identifiable intangible assets were as follows:

The increase in intellectual property since December 31, 2009 was due to software and technology assets acquired through immaterial business acquisitions.

The aggregate amortization expense (actual and estimated) for identifiable intangible assets for the following periods is:
