Significant Accounting Policies |
Use Of Estimates | Use of estimates The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates, judgments and assumptions that affect the amounts reported in the consolidated financial statements. These estimates, judgments and assumptions are evaluated on an ongoing basis. We base our estimates on historical experience and on various other assumptions that we believe are reasonable at that time, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from those estimates. In particular, significant estimates, judgments and assumptions include those related to: (i) revenue recognition, (ii) allowance for doubtful accounts, (iii) testing goodwill for impairment, (iv) the valuation of acquired intangible assets, (v) the valuation of long-lived assets, (vi) the recognition of contingencies, (vii) restructuring accruals, (viii) acquisition accruals and pre-acquisition contingencies, (ix) asset retirement obligations, (x) the realization of investment tax credits, (xi) the valuation of stock options granted and liabilities related to share-based payments, including the valuation of our long-term incentive plan, (xii) the valuation of financial instruments, (xiii) the valuation of pension assets and obligations, and (xiv) accounting for income taxes.
Basis Of Presentation | Basis of Presentation In June 2009, the Financial Accounting Standards Board (FASB) issued Statement No. 168, "The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles, a replacement of FASB Statement No. 162" (the Codification). The Codification has become the single source of authoritative non-government U.S GAAP, superseding various existing authoritative accounting pronouncements. The Codification eliminates the GAAP hierarchy contained in Statement No. 162 and establishes one level of authoritative U.S. GAAP. All other U.S. GAAP literature is considered non-authoritative. This Codification is effective for financial statements issued for interim and annual periods ending after September 15, 2009. We adopted the Codification in our first quarter of Fiscal 2010. There was no change to our consolidated financial statements due to the implementation of the Codification other than changes in reference to various authoritative accounting pronouncements in our Notes to consolidated financial statements.
Reclassification | Reclassifications During the quarter ended September 30, 2010 a purchase price adjustment was made to the acquisition of Burntsand Inc., acquired on May 27, 2010, which resulted in the fair value of the net assets acquired exceeding the purchase price. In accordance with Accounting Standards Codification (ASC) Topic 805 "Business Combinations" (ASC Topic 805), negative goodwill was recognized upon the acquisition of the business. For more details on this purchase price adjustment, see note 17. As a result of this purchase price adjustment, the opening retained earnings and certain balance sheet amounts presented in this Annual Report on Form 10-K have been retroactively adjusted, in accordance with ASC Topic 805, from those published in our Annual Report on Form 10-K for the year ended June 30, 2010.
Cash And Cash Equivalents | Cash and cash equivalents Cash and cash equivalents include investments that have terms to maturity of three months or less. Cash equivalents are recorded at cost and typically consist of term deposits, commercial paper, certificates of deposit and short-term interest bearing investment-grade securities of major banks in the countries in which we operate.
Capital Assets | Capital assets Capital assets are stated at cost and are depreciated on a straight-line basis over the estimated useful lives of the related assets. Gains and losses on asset disposals are taken into income in the year of disposition. Fully depreciated capital assets are retired from the balance sheet when they are no longer in use. The following represents the estimated useful lives of capital assets:
Furniture and fixtures |  | 5 years
Office equipment |  | 5 years
Computer hardware |  | 3 years
Computer software |  | 3 years
Leasehold improvements |  | Lesser of the lease term or 5 years
Building |  | 40 years
Business Combinations | Business combinations In Fiscal 2010, we adopted ASC Topic 805 which revised the accounting guidance that we were required to apply for our acquisitions in comparison to prior fiscal years. The underlying principles are similar to the previous guidance and require that we recognize separately from goodwill the identifiable assets acquired and the liabilities assumed, generally at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While we use our best estimates and assumptions as a part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the acquisition date, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill to the extent that we identify adjustments to the preliminary purchase price allocation. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our Consolidated Statements of Income. As a result of adopting the revised accounting guidance in accordance with ASC Topic 805 as of the beginning of Fiscal 2010, certain of our policies differ when accounting for acquisitions in Fiscal 2010 and future periods in comparison to the accounting for acquisitions in Fiscal 2010 and prior periods, including:
| • |  | The direct transaction costs associated with the business combination are expensed as incurred (prior to Fiscal 2010, direct transaction costs were included as a part of the purchase price);
| • |  | The costs to exit or restructure certain activities of an acquired company are accounted for separately from the business combination (prior to Fiscal 2010, these restructuring and exit costs were included as a part of the assumed obligations in deriving the purchase price allocation); and
| • |  | Changes in estimates associated with income tax valuation allowances or uncertain tax positions after the measurement period are generally recognized as income tax expense with application of this policy also applied prospectively to all of our business combinations regardless of the acquisition date (prior to Fiscal 2010, any such changes were generally included as a part of the purchase price allocation indefinitely).
Costs to exit or restructure certain activities of an acquired company or our internal operations are accounted for as one-time termination and exit costs pursuant to ASC Topic 420, "Exit or Disposal Cost Obligations" (ASC Topic 420), and, as noted above, are accounted for separately from the business combination. For a given acquisition, we generally identify certain pre-acquisition contingencies as of the acquisition date and may extend our review and evaluation of these pre-acquisition contingencies throughout the measurement period in order to obtain sufficient information to assess whether we include these contingencies as a part of the purchase price allocation and, if so, to determine the estimated amounts. If we determine that a pre-acquisition contingency (non-income tax related) is probable in nature and estimable as of the acquisition date, we record our best estimate for such a contingency as a part of the preliminary purchase price allocation. We often continue to gather information for and evaluate our pre-acquisition contingencies throughout the measurement period and if we make changes to the amounts recorded or if we identify additional pre-acquisition contingencies during the measurement period, such amounts will be included in the purchase price allocation during the measurement period and, subsequently, in our results of operations. Uncertain tax positions and tax related valuation allowances assumed in connection with a business combination are initially estimated as of the acquisition date and we reevaluate these items quarterly with any adjustments to our preliminary estimates being recorded to goodwill provided that we are within the measurement period and we continue to collect information relating to facts and circumstances that existed at acquisition date. Changes to these uncertain tax positions and tax related valuation allowances made subsequent to the measurement period or if they relate to facts and circumstances that do not exist at acquisition date, are recorded in our provision for income taxes in our Consolidated Statement of Income.
Acquired Intangibles | Acquired intangibles Acquired intangibles consist of acquired technology and customer relationships associated with various acquisitions. Acquired technology is initially recorded at fair value based on the present value of the estimated net future income-producing capabilities of software products acquired on acquisitions. We amortize acquired technology over its estimated useful life on a straight-line basis. Customer relationships represent relationships that we have with customers of the acquired companies and are either based upon contractual or legal rights or are considered separable; that is, capable of being separated from the acquired entity and being sold, transferred, licensed, rented or exchanged. These customer relationships are initially recorded at their fair value based on the present value of expected future cash flows. We amortize customer relationships on a straight-line basis over their estimated useful lives. We continually evaluate the remaining estimated useful life of our intangible assets being amortized to determine whether events and circumstances warrant a revision to the remaining period of amortization. Goodwill Goodwill represents the excess of the purchase price in a business combination over the fair value of net tangible and intangible assets acquired. The carrying amounts of goodwill and other intangible assets are periodically reviewed for impairment (at least annually for goodwill and indefinite lived intangible assets) and whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. Our operations are analyzed by management and our chief operating decision maker (CODM) as being part of a single industry segment: the design, development, marketing and sales of enterprise content management software and solutions. For Fiscal 2010 and earlier years, we allocated goodwill to reporting units on a geographical basis comprising of three reporting units: North America, Europe and "Other"; "Other" primarily consists of Australia, Brazil, Japan, Singapore and the United Arab Emirates. During Fiscal 2011, pursuant to an internal reorganization of subsidiaries to consolidate our intellectual property we moved to a single reporting unit for the purposes of allocation of goodwill. The primary valuation method selected was the market approach. Our annual impairment analysis of goodwill was performed as of April 1, 2011. This analysis indicated that the fair value of our reporting unit was in excess of its carrying value and therefore there was no impairment of goodwill required to be recorded for Fiscal 2011 (no impairments were recorded for Fiscal 2010 and Fiscal 2009).

Impairment Of Long-Lived Assets | Impairment of long-lived assets We account for the impairment and disposition of long-lived assets in accordance with ASC Topic 360, "Property, Plant, and Equipment" (ASC Topic 360). We test long-lived assets or asset groups, such as capital assets and definite lived intangible assets, for recoverability when events or changes in circumstances indicate that their carrying amount may not be recoverable. Circumstances which could trigger a review include, but are not limited to: significant adverse changes in the business climate or legal factors; current period cash flow or operating losses combined with a history of losses or a forecast of continuing losses associated with the use of the asset; and a current expectation that the asset will more likely than not be sold or disposed of before the end of its estimated useful life. Recoverability is assessed based on comparing the carrying amount of the asset to the aggregate pre-tax undiscounted cash flows expected to result from the use and eventual disposal of the asset or asset group. Impairment is recognized when the carrying amount is not recoverable and exceeds the fair value of the asset or asset group. The impairment loss, if any, is measured as the amount by which the carrying amount exceeds fair value, which for this purpose is based upon the discounted projected future cash flows of the asset or asset group. We have not recorded any impairment charges for long-lived assets during Fiscal 2011 and Fiscal 2009, and during Fiscal 2010 we recorded an impairment charge to intangible assets of $0.3 million. See note 16 for further details.
Derivative Financial Instruments | Derivative Financial Instruments During Fiscal 2011, we used derivative financial instruments to manage foreign currency rate risk. We account for these instruments in accordance with ASC Topic 815, "Derivatives and Hedging" (ASC Topic 815), which requires that every derivative instrument be recorded on the balance sheet as either an asset or liability measured at its fair value as of the reporting date. ASC Topic 815 also requires that changes in our derivatives financial instruments' fair values be recognized in earnings; unless specific hedge accounting and documentation criteria are met (i.e. the instruments are accounted for as hedges). We recorded the effective portions of the gain or loss on derivative financial instruments that were designated as cash flow hedges in accumulated other comprehensive income in our accompanying consolidated balance sheets. Any ineffective or excluded portion of a designated cash flow hedge, if applicable, was recognized in our consolidated statement of income.
Allowance For Doubtful Accounts | Allowance for doubtful accounts We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of customers to make payments. We evaluate the creditworthiness of our customers prior to order fulfillment and based on these evaluations, we adjust our credit limit to the respective customer. In addition to these evaluations, we conduct on-going credit evaluations of our customers' payment history and current creditworthiness. The allowance is maintained for 100% of all accounts deemed to be uncollectible and, for those receivables not specifically identified as uncollectible, an allowance is maintained for a specific percentage of those receivables based upon the aging of accounts, our historical collection experience and current economic expectations. To date, the actual losses have been within our expectations. No single customer accounted for more than 10% of the accounts receivable balance as of June 30, 2011 and 2010.
Asset Retirement Obligations | Asset retirement obligations We account for asset retirement obligations in accordance with ASC Topic 410, "Asset Retirement and Environmental Obligations" (ASC Topic 410), which applies to certain obligations associated with "leasehold improvements" within our leased office facilities. ASC Topic 410 requires that a liability be initially recognized for the estimated fair value of the obligation when it is incurred. The associated asset retirement cost is capitalized as part of the carrying amount of the long-lived asset and depreciated over the remaining life of the underlying asset and the associated liability is accreted to the estimated fair value of the obligation at the settlement date through periodic accretion charges recorded within general and administrative expenses. When the obligation is settled, any difference between the final cost and the recorded amount is recognized as income or loss on settlement.
Revenue Recognition | Revenue recognition a) License revenues We recognize revenues in accordance with ASC Topic 985-605, "Software Revenue Recognition" (ASC Topic 985-605). We record product revenues from software licenses and products when persuasive evidence of an arrangement exists, the software product has been shipped, there are no significant uncertainties surrounding product acceptance by the customer, the fees are fixed and determinable, and collection is considered probable. We use the residual method to recognize revenues on delivered elements when a license agreement includes one or more elements to be delivered at a future date if evidence of the fair value of all undelivered elements exists. If an undelivered element for the arrangement exists under the license arrangement, revenues related to the undelivered element is deferred based on vendor-specific objective evidence (VSOE) of the fair value of the undelivered element. Our multiple-element sales arrangements include arrangements where software licenses and the associated post contract customer support (PCS) are sold together. We have established VSOE of the fair value of the undelivered PCS element based on the contracted price for renewal PCS included in the original multiple element sales arrangement, as substantiated by contractual terms and our significant PCS renewal experience, from our existing worldwide base. Our multiple element sales arrangements generally include irrevocable rights for the customer to renew PCS after the bundled term ends. The customer is not subject to any economic or other penalty for failure to renew. Further, the renewal PCS options are for services comparable to the bundled PCS and cover similar terms. It is our experience that customers generally exercise their renewal PCS option. In the renewal transaction, PCS is sold on a stand-alone basis to the licensees one year or more after the original multiple element sales arrangement. The exercised renewal PCS price is consistent with the renewal price in the original multiple element sales arrangement, although an adjustment to reflect consumer price changes is not uncommon. If VSOE of fair value does not exist for all undelivered elements, all revenues are deferred until sufficient evidence exists or all elements have been delivered. We assess whether payment terms are customary or extended in accordance with normal practice relative to the market in which the sale is occurring. Our sales arrangements generally include standard payment terms. These terms effectively relate to all customers, products, and arrangements regardless of customer type, product mix or arrangement size. Exceptions are only made to these standard terms for certain sales in parts of the world where local practice differs. In these jurisdictions, our customary payment terms are in line with local practice. b) Service revenues Service revenues consist of revenues from consulting, implementation, training and integration services. These services are set forth separately in the contractual arrangements such that the total price of the customer arrangement is expected to vary as a result of the inclusion or exclusion of these services. For those contracts where the services are not essential to the functionality of any other element of the transaction, we determine VSOE of fair value for these services based upon normal pricing and discounting practices for these services when sold separately. These consulting and implementation services contracts are primarily time and materials based contracts that are, on average, less than six months in length. Revenues from these services is recognized at the time such services are rendered as the time is incurred by us. We also enter into contracts that are primarily fixed fee arrangements wherein the services are not essential to the functionality of a software element. In such cases, the proportional performance method is applied to recognize revenues. Revenues from training and integration services are recognized in the period in which these services are performed. c) Customer support revenues Customer support revenues consist of revenues derived from contracts to provide PCS to license holders. These revenues are recognized ratably over the term of the contract. Advance billings of PCS are not recorded to the extent that the term of the PCS has not commenced and payment has not been received.
Deferred Revenue | Deferred revenues Deferred revenues primarily relates to support agreements which have been paid for by customers prior to the performance of those services. Generally, the services will be provided in the twelve months after the signing of the agreement.
Long-Term Sales Contracts | Long-term sales contracts We entered into certain long-term sales contracts involving the sale of integrated solutions that include the modification and customization of software and the provision of services that are essential to the functionality of the other elements in this arrangement. As prescribed by ASC Topic 985-605, we recognize revenues from such arrangements in accordance with the contract accounting guidelines in ASC Topic 605-35, "Construction-Type and Production-Type Contracts" (ASC Topic 605-35), after evaluating for separation of any non-ASC Topic 605-35 elements in accordance with the provisions of ASC Topic 605-25, "Multiple-Element Arrangements" (ASC Topic 605-25). When circumstances exist that allow us to make reasonably dependable estimates of contract revenues, contract costs and the progress of the contract to completion, we account for sales under such long-term contracts using the percentage-of-completion (POC) method of accounting. Under the POC method, progress towards completion of the contract is measured based upon either input measures or output measures. We measure progress towards completion based upon an input measure and calculate this as the proportion of the actual hours incurred compared to the total estimated hours. For training and integration services rendered under such contracts, revenues are recognized as the services are rendered. We will review, on a quarterly basis, the total estimated remaining costs to completion for each of these contracts and apply the impact of any changes on the POC prospectively. If at any time we anticipate that the estimated remaining costs to completion will exceed the value of the contract, the loss will be recognized immediately. When circumstances exist that prevent us from making reasonably dependable estimates of contract revenues, we account for sales under such long-term contracts using the completed contract method.
Sales To Resellers And Channel Partners | Sales to resellers and channel partners We execute certain sales contracts through resellers and distributors (collectively, resellers) and also large, well-capitalized partners such as SAP AG and Accenture Inc. (collectively, channel partners). We recognize revenues relating to sales through resellers when all the recognition criteria have been met—in other words, persuasive evidence of an arrangement exists, delivery has occurred in the reporting period, the fee is fixed and determinable, and collectability is probable. Typically, we recognize revenues to resellers only after the reseller communicates the occurrence of end-user sales to us, since we do not have privity of contract with the end-user. In addition we assess the creditworthiness of each reseller and if the reseller is newly formed, undercapitalized or in financial difficulty any revenues expected to emanate from such resellers are deferred and recognized only when cash is received and all other revenue recognition criteria are met. We recognize revenues relating to sales through channel partners in the reporting period in which we receive evidence, from the channel partner, of end user sales (collectively, the documentation) and all other revenue recognition criteria have been met. As a result, if the documentation is not received within a given reporting period we recognize the revenues in a period subsequent to the period in which the channel partner completes the sale to the end user.
Rights of Return And Other Incentives | Rights of return and other incentives We do not generally offer rights of return or any other incentives such as concessions, product rotation, or price protection and, therefore, do not provide for or make estimates of rights of return and similar incentives.
Research And Development Costs | Research and development costs Research and development costs internally incurred in creating computer software to be sold, licensed or otherwise marketed are expensed as incurred unless they meet the criteria for deferral and amortization, as described in ASC Topic 985-20, "Costs of Software to be Sold, Leased, or Marketed" (ASC Topic 985-20). In accordance with ASC Topic 985-20, costs related to research, design and development of products are charged to expenses as incurred and capitalized between the dates that the product is considered to be technologically feasible and is considered to be ready for general release to customers. In our historical experience, the dates relating to the achievement of technological feasibility and general release of the product have substantially coincided. In addition, no significant costs are incurred subsequent to the establishment of technological feasibility. As a result, we do not capitalize any research and development costs relating to internally developed software to be sold, licensed or otherwise marketed.
Income Taxes | Income taxes We account for income taxes in accordance with ASC Topic 740, "Income Taxes" (ASC Topic 740). Deferred tax assets and liabilities arise from temporary differences between the tax bases of assets and liabilities and their reported amounts in the consolidated financial statements that will result in taxable or deductible amounts in future years. These temporary differences are measured using enacted tax rates. A valuation allowance is recorded to reduce deferred tax assets to the extent that we consider it is more likely than not that a deferred tax asset will not be realized. In determining the valuation allowance, we consider factors such as the reversal of deferred income tax liabilities, projected taxable income, and the character of income tax assets and tax planning strategies. A change to these factors could impact the estimated valuation allowance and income tax expense. We account for our uncertain tax provisions by using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not, based solely on the technical merits, that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the appropriate amount of the benefit to recognize. The amount of benefit to recognize is measured as the maximum amount which is more likely than not to be realized. The tax position is derecognized when it is no longer more likely than not capable of being sustained. On subsequent recognition and measurement the maximum amount which is more likely than not to be recognized at each reporting date will represent the Company's best estimate, given the information available at the reporting date, although the outcome of the tax position is not absolute or final. Upon adopting the revisions in ASC Topic 740, we elected to follow an accounting policy to classify accrued interest related to liabilities for income taxes within the "Interest expense" line and penalties related to liabilities for income taxes within the "Other expense" line of our Consolidated Statements of Income (see note 13 for more details).
Fair Value Of Financial Instruments | Fair value of financial instruments Carrying amounts of certain financial instruments, including cash and cash equivalents, accounts receivable and accounts payable (trade and accrued liabilities) approximate their fair value due to the relatively short period of time between origination of the instruments and their expected realization. The fair value of our total long-term debt approximates its carrying value. We apply the provisions of ASC 820, "Fair Value Measurements and Disclosures", to our derivative financial instruments that we are required to carry at fair value pursuant to other accounting standards (see note 14 for more details).
Foreign Currency Translation | Foreign currency translation Our consolidated financial statements are presented in U.S. dollars. In general, the functional currency of our subsidiaries is the local currency. For such subsidiary, assets and liabilities denominated in foreign currencies are translated into U.S dollars at the exchange rates in effect at balance sheet dates and revenues and expenses are translated at the average exchange rates prevailing during the month of the transaction. The effect of foreign currency translation adjustments not affecting net income are included in Shareholders' equity under the "Cumulative translation adjustment" account as a component of "Accumulated other comprehensive income (loss)". Transactional foreign currency gains (losses) are included in the consolidated statements of income under the line item "Other income (expense)" (For details see note 21).
Restructuring Charges | Restructuring charges We record restructuring charges relating to contractual lease obligations and other exit costs in accordance with ASC Topic 420, "Exit or Disposal Cost Obligations" (ASC Topic 420). ASC Topic 420 requires that a liability for a cost associated with an exit or disposal activity be recognized and measured initially at its fair value in the period in which the liability is incurred. In order to incur a liability pursuant to ASC Topic 420, our management must have established and approved a plan of restructuring in sufficient detail. A liability for a cost associated with involuntary termination benefits is recorded when benefits have been communicated and a liability for a cost to terminate an operating lease or other contract is incurred when the contract has been terminated in accordance with the contract terms or we have ceased using the right conveyed by the contract, such as vacating a leased facility. The recognition of restructuring charges requires us to make certain judgments regarding the nature, timing and amount associated with the planned restructuring activities, including estimating sub-lease income and the net recoverable amount of equipment to be disposed of. At the end of each reporting period, we evaluate the appropriateness of the remaining accrued balances (See note 16 for more details).
Litigation | Litigation We are currently involved in various claims and legal proceedings. Quarterly, we review the status of each significant matter and assess our potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount can be reasonably estimated, we accrue a liability for the estimated loss in accordance with ASC Topic 450, "Contingencies". Net income per share Basic net income per share is computed using the weighted average number of Common Shares outstanding including contingently issuable shares where the contingency has been resolved. Diluted net income per share is computed using the weighted average number of Common Shares and stock equivalents outstanding using the treasury stock method during the year (See note 22 for more details).
Net Income Per Share | Net income per share Basic net income per share is computed using the weighted average number of Common Shares outstanding including contingently issuable shares where the contingency has been resolved. Diluted net income per share is computed using the weighted average number of Common Shares and stock equivalents outstanding using the treasury stock method during the year (See note 22 for more details).
Share-based Payment | Share-based payment We measure share-based compensation costs, in accordance with ASC Topic 718, "Compensation – Stock Compensation" (ASC Topic 718) on the grant date, based on the calculated fair value of the award. We have elected to treat awards with graded vesting as a single award when estimating fair value. Compensation cost is recognized on a straight-line basis over the employee requisite service period, which in our circumstances is the stated vesting period of the award, provided that total compensation cost recognized at least equals the pro rata value of the award that has vested. Compensation cost is initially based on the estimated number of options for which the requisite service is expected to be rendered. This estimate is adjusted in the period once actual forfeitures are known (See note 12 for more details).
Accounting For Pensions, Post-Retirement And Post-Employment Benefits | Accounting for Pensions, post-retirement and post-employment benefits Pension expense is accounted for in accordance with ASC Topic 715, "Compensation—Retirement Benefits" (ASC Topic 715). Pension expense consists of: actuarially computed costs of pension benefits in respect of the current year of service, imputed returns on plan assets (for funded plans) and imputed interest on pension obligations. The expected costs of post retirement benefits, other than pensions, are accrued in the financial statements based upon actuarial methods and assumptions. The over-funded or under-funded status of defined benefit pension and other post retirement plans are recognized as an asset or a liability (with the offset to "Accumulated Other Comprehensive Income" within "Shareholders' equity"), respectively, on the balance sheet (See note 10 for more details).

If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=6367646&loc=d3e18726-107790 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 605 -SubTopic 10 -Section S99 -Paragraph 1 -Subparagraph (SAB TOPIC 13.B.Q1) -URI http://asc.fasb.org/extlink&oid=6600647&loc=d3e214044-122780 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher AICPA -Name Accounting Principles Board Opinion (APB) -Number 22 -Paragraph 8, 12, 13 -LegacyDoc This reference is SUPERSEDED by the Accounting Standards Codification effective for interim and annual periods ending after September 15, 2009.
