Adoption of New Accounting Pronouncement | Adoption of New Accounting Pronouncement On January 1, 2012, the Company adopted 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income (“ASU 2011-05”) which requires presentation of the components of net income (loss) and other comprehensive income either as one continuous statement or as two consecutive statements and eliminates the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity. The standard does not change the items that must be reported in other comprehensive income, how such items are measured or when they must be reclassified to net income. Also, in December of 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2011-12, Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05 (ASU 2011-12). On January 1, 2012, the Company adopted 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs (“ASU 2011-04”). The amendments in ASU 2011-04 change the wording used to describe many of the requirements in U.S. Generally Accepted Accounting Principles (“U.S. GAAP”) for measuring fair value and for disclosing information about fair value measurements. Some of the amendments clarify FASB’s intent about the application of existing fair value measurement and disclosure requirements. Other amendments change a particular principle or requirement for measuring fair value or for disclosing information about fair value measurements.
Fair Value of Financial Instruments | ASC 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. ASC 820 establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:
| • |  | Level 1 Inputs—Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.
| • |  | Level 2 Inputs—Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.
| • |  | Level 3 Inputs—Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.
Earnings per share | Basic earnings per share is computed on the basis of weighted average outstanding common shares. Diluted earnings per share is computed on the basis of basic weighted average outstanding common shares adjusted for the dilutive effect of stock options and other outstanding dilutive securities.
Segment Information | The Company’s chief operating decision maker, together with other senior management personnel, currently focus their review of consolidated financial information and the allocation of resources based on reporting of operating results, including revenues and operating income, for the geographic regions of the Americas, EMEA and Asia/Pacific and the Corporate line item. The Company’s products are sold and supported through distribution networks covering these three geographic regions, with each distribution network having its own sales force. The Company supplements its distribution networks with independent reseller and/or distributor arrangements. All administrative costs that are not directly attributable or reasonably allocable to a geographic segment are tracked in the Corporate line item. As such, the Company has concluded that its three geographic regions and Corporate line item are its reportable operating segments. During the year ended December 31, 2011, the Company changed its segment operating income reporting measure to exclude certain corporate general and administrative expenses. Previously, corporate expenses were allocated to the segments. In addition, amortization expense on acquired intangibles is no longer allocated to the individual segments. All periods presented have been recast to reflect these changes. The Company allocates segment support expenses such as global product development, business operations, and product management based upon percentage of revenue per segment. Depreciation and amortization costs are allocated as a percentage of the headcount by segment. The Corporate line item consists of the corporate overhead costs that are not allocated to operating segments. Corporate overhead costs relate to human resources, finance, legal, accounting, merger and acquisition activity and amortization of acquisition-related intangibles and other costs that are not considered when management evaluates segment performance.
