The estimation of residual values requires the Company to make assumptions regarding the age and mileage of the car at the time of disposal, as well as the general used vehicle market conditions at the time of sale, including the impact of seasonality on vehicle residuals. The Company evaluates estimated residual values at least quarterly, and adjusts depreciation rates accordingly, on a prospective basis. Differences between actual residual values and those estimated by the Company result in a gain or loss on disposal and are recorded as an adjustment to depreciation expense. Actual timing of disposal either shorter or longer than the life used for depreciation purposes could result in a loss or gain on sale. Vehicle rental companies bear residual value risk for these vehicles, which are referred to as "Non-Program Vehicles".

In some cases, the sales proceeds are received directly from auctions, with any shortfall in value being paid by the vehicle manufacturer. With certain other vehicle manufacturers, the entire balance of proceeds from vehicle sales comes directly from the manufacturer. In either case, the Company bears the risk of collectability on the receivable from the vehicle manufacturer. The Company monitors its vehicle manufacturer receivables based on time outstanding, manufacturer strength and length of the relationship.

We also estimate the residual value of the applicable revenue earning equipment at the expected time of disposal. The residual values for rental vehicles are affected by many factors, including make, model and options, age, physical condition, mileage, sale location, time of the year and channel of disposition (e.g.,</font><font style="font-family:inherit;font-size:10pt;">&#160;</font><font style="font-family:Arial;font-size:10pt;">auction, retail, dealer direct). The residual value for rental equipment is affected by factors which include equipment age and amount of usage. Depreciation is recorded on a straight-line basis over the estimated holding period. Depreciation rates are reviewed on a quarterly basis based on management's ongoing assessment of present and estimated future market conditions, their effect on residual values at the time of disposal and the estimated holding periods. Market conditions for used vehicle and equipment sales can also be affected by external factors such as the economy, natural disasters, fuel prices and incentives offered by manufacturers of new cars. These key factors are considered when estimating future residual values and assessing depreciation rates. As a result of this ongoing assessment, we make periodic adjustments to depreciation rates of revenue earning equipment in response to changed market conditions. Upon disposal of revenue earning equipment, depreciation expense is adjusted for the difference between the net proceeds received and the remaining net book value.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:justify;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">Within Donlen, revenue earning equipment is under longer term lease agreements with our customers.

An entity should provide the disclosures required by those amendments retrospectively for all comparative periods presented. ASU 2011-11 is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. We plan to adopt ASU 2011-11 on January 1, 2013, as required, but do not believe this guidance will have a significant impact on our consolidated financial statements or financial statement disclosures.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:justify;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">In July 2012, the FASB issued ASU No. 2012-02, "Intangibles&#8212;Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment," or "ASU 2012-02" which states that an entity has the option first to assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that an 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 determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount. This provision is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. This accounting guidance is not expected to have a material impact on our consolidated financial statements or financial statement disclosures.</font></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:justify;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">In February 2013, </font><font style="font-family:Arial;font-size:10pt;color:#212100;">the FASB issued ASU No. 2013-02, "Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income," </font><font style="font-family:Arial;font-size:10pt;">or "ASU 2013-02" which requires disclosure of significant amounts reclassified out of accumulated other comprehensive income by component and their corresponding effect on the respective line items of net income.

ASU 2010-06 also clarifies existing fair value disclosures about the level of disaggregation and about inputs and valuation techniques used to measure fair value. The Company adopted the provisions of ASU 2010-06 regarding disclosures about transfers into and out of Levels&#160;1 and 2 as required on January&#160;1, 2010 and adopted the remaining provisions of ASU 2010-06 regarding separate disclosures about purchases, sales, issuances, and settlements relating to Level&#160;3 measurements as required on January&#160;1, 2011. The adoption of this latest provision had no impact on the Company's financial statements as the Company has no Level&#160;3 measurements.</font></p> <p style="FONT-FAMILY: times;"><font size="2">&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;In May 2011, the FASB issued ASU 2011-04, "Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S.&#160;GAAP and IFRS" ("ASU 2011-04"), which amends U.S.&#160;GAAP to converge U.S.&#160;GAAP and International Financial Reporting Standards ("IFRS") by changing the wording used to describe many of the requirements in U.S.&#160;GAAP for measuring fair value and for disclosing information about fair value measurements. ASU 2011-04 is effective for interim and annual periods beginning after December&#160;15, 2011; early adoption is not permitted. The Company adopted ASU 2011-04 on January&#160;1, 2012, as required, but does not believe this guidance will have a significant impact on the Company's consolidated financial statements.</font></p> <p style="FONT-FAMILY: times;"><font size="2">&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;In June 2011, the FASB issued ASU 2011-05, "Comprehensive Income&#8212;Presentation of Comprehensive Income" ("ASU 2011-05"). ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of stockholders' equity. It requires an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In December 2011, the FASB issued ASU&#160;2011-12, "Comprehensive Income&#8212;Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in ASU&#160;2011-05," to defer the effective date of the specific requirement to present items that are reclassified out of accumulated other comprehensive income to net income alongside their respective components of net income and other comprehensive income. All other provisions of this update, which are to be applied retrospectively, are effective for fiscal years, and interim periods within those years, beginning after December&#160;15, 2011. The Company adopted ASU 2011-05 and ASU 2011-12 on January&#160;1, 2012, as required.</font></p> <p style="FONT-FAMILY: times;"><font size="2">&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;In December 2011, the FASB issued ASU 2011-11, "Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities" ("ASU&#160;2011-11") to amend the requirement for an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position.
