Our policy is to periodically review the estimated useful lives of our fixed assets. Our review during the three months ended June 30, 2012 indicated lower estimated useful lives for our gaming terminals deployed to our U.K. licensed betting office ("LBO") customers relative to historical estimates due to market changes that have altered the replacement cycle of these terminals. As a result, effective April 1, 2012, we revised the estimated useful lives of our gaming terminals currently deployed to our LBO customers.

Recently Issued Accounting Guidance In May 2011, the Financial Accounting Standards Board (the "FASB") issued guidance to clarify the intent of the application of existing fair value measurement and disclosure requirements and amend certain requirements for measuring fair value or for disclosing information about fair value measurements. The guidance limits the highest-and-best-use measure to non-financial assets, permits certain financial assets and liabilities with offsetting positions in market or counter-party credit risks to be measured at a net basis, and provides guidance on the applicability of premiums and discounts in fair value measurement. Additionally, for fair value measurements categorized within Level 3 of the fair value hierarchy, the new guidance clarifies that quantitative disclosure about unobservable inputs should be disclosed and requires a description of the valuation processes and the sensitivity of the fair value measurements to changes in unobservable inputs and the interrelationships between those inputs. We adopted the guidance on January 1, 2012. The adoption did not have a material impact on our financial statements. In June 2011, the FASB issued guidance on presentation of comprehensive income. The guidance eliminates the option to report other comprehensive income and its components in the statement of stockholders' equity. Instead, an entity is required to present net income and other comprehensive income either in one continuous statement or in two separate but consecutive statements. The guidance also requires presentation of reclassification adjustments from other comprehensive income to net income on the face of the financial statements. We adopted the guidance on January 1, 2012, resulting in a change in the presentation of comprehensive income for the three and nine months ended September 30, 2012 and 2011. In September 2011, the FASB issued guidance on testing goodwill for impairment. The guidance provides an entity with the option to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If an entity determines that this is the case, it is required to perform the currently prescribed two-step goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment loss to be recognized for that reporting unit (if any). If an entity determines the fair value of a reporting unit is greater than its carrying amount, then the two-step goodwill impairment test is not required. We adopted the guidance on January 1, 2012, and will apply the guidance in our next annual goodwill impairment evaluation. In July 2012, the FASB issued guidance on testing indefinite-lived intangible assets, other than goodwill, for impairment. The guidance is effective for fiscal years beginning after September 15, 2012 and early adoption is permitted. The guidance provides an entity with the option to first perform a qualitative assessment to determine whether it is more likely than not that the indefinite-lived intangible asset is impaired. If, after assessing the totality of events and circumstances, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. However, if an entity concludes otherwise, then it is required to perform the currently prescribed quantitative impairment test by comparing the fair value of the asset with the carrying amount. We adopted the guidance on July 1, 2012, and will apply the guidance in our next annual indefinite-lived intangible asset impairment evaluation.

Significant Accounting Policies

We describe our significant accounting policies in Note 1 of the Notes to Consolidated Financial Statements in our 2011 Annual Report on Form 10-K. There have been no changes to our significant accounting policies during the nine months ended September 30, 2012, except as discussed below.

Our policy is to periodically review the estimated useful lives of our fixed assets. Our review during the three months ended June 30, 2012 indicated lower estimated useful lives for our gaming terminals deployed to our U.K. licensed betting office ("LBO") customers relative to historical estimates due to market changes that have altered the replacement cycle of these terminals. As a result, effective April 1, 2012, we revised the estimated useful lives of our gaming terminals currently deployed to our LBO customers. This change increased depreciation expense for the three and nine months ended September 30, 2012 but was not material to our consolidated financial position or results of operations as of and for the three and nine months ended September 30, 2012.

Recently Issued Accounting Guidance

In May 2011, the Financial Accounting Standards Board (the "FASB") issued guidance to clarify the intent of the application of existing fair value measurement and disclosure requirements and amend certain requirements for measuring fair value or for disclosing information about fair value measurements. The guidance limits the highest-and-best-use measure to non-financial assets, permits certain financial assets and liabilities with offsetting positions in market or counter-party credit risks to be measured at a net basis, and provides guidance on the applicability of premiums and discounts in fair value measurement. Additionally, for fair value measurements categorized within Level 3 of the fair value hierarchy, the new guidance clarifies that quantitative disclosure about unobservable inputs should be disclosed and requires a description of the valuation processes and the sensitivity of the fair value measurements to changes in unobservable inputs and the interrelationships between those inputs. We adopted the guidance on January 1, 2012. The adoption did not have a material impact on our financial statements.

In June 2011, the FASB issued guidance on presentation of comprehensive income. The guidance eliminates the option to report other comprehensive income and its components in the statement of stockholders' equity. Instead, an entity is required to present net income and other comprehensive income either in one continuous statement or in two separate but consecutive statements. The guidance also requires presentation of reclassification adjustments from other comprehensive income to net income on the face of the financial statements. We adopted the guidance on January 1, 2012, resulting in a change in the presentation of comprehensive income for the three and nine months ended September 30, 2012 and 2011.

In September 2011, the FASB issued guidance on testing goodwill for impairment. The guidance provides an entity with the option to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If an entity determines that this is the case, it is required to perform the currently prescribed two-step goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment loss to be recognized for that reporting unit (if any). If an entity determines the fair value of a reporting unit is greater than its carrying amount, then the two-step goodwill impairment test is not required. We adopted the guidance on January 1, 2012, and will apply the guidance in our next annual goodwill impairment evaluation.

In July 2012, the FASB issued guidance on testing indefinite-lived intangible assets, other than goodwill, for impairment. The guidance is effective for fiscal years beginning after September 15, 2012 and early adoption is permitted. The guidance provides an entity with the option to first perform a qualitative assessment to determine whether it is more likely than not that the indefinite-lived intangible asset is impaired. If, after assessing the totality of events and circumstances, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. However, if an entity concludes otherwise, then it is required to perform the currently prescribed quantitative impairment test by comparing the fair value of the asset with the carrying amount. We adopted the guidance on July 1, 2012, and will apply the guidance in our next annual indefinite-lived intangible asset impairment evaluation.
