Under the asset and liability method of ASC 740, deferred assets and liabilities are recognized for the future costs and benefits attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. The Company periodically reviews the requirements for a valuation allowance and makes adjustments to such allowances when changes in circumstances result in changes in the Company&amp;#8217;s judgment about the future realization of deferred tax assets. ASC 740 places more emphasis on historical information, such as the Company&amp;#8217;s cumulative operating results and its current year results than it places on estimates of future taxable income. Therefore, the Company has added &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$2.1 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; to its valuation allowance in the &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;six months ended June 30, 2013&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;, resulting in a cumulative balance of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$91.0 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; as of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;June&amp;#160;30, 2013&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;. In addition, the Company has recorded &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$0.7 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; of tax expense during the &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;six months ended June 30, 2013&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; which is primarily attributable to differences between the financial statement carrying amounts of past acquisitions of certain indefinite-lived intangible assets and their respective tax bases. &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;The Company has a cumulative net deferred tax liability of&lt;/font&gt;&lt;font style="font-family:inherit;font-size:11pt;"&gt; &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$7.7 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; at &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;June&amp;#160;30, 2013&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;. The Company intends to maintain a valuation allowance until evidence would support the conclusion that it is more likely than not that the deferred tax asset could be realized. The Company considered all income sources, including other comprehensive income, in determining the amount of tax recorded. During the &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;six months ended June 30, 2013&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;, the Company did not record a current income tax provision for U.S. Federal income tax purposes since our deferred tax assets are fully reserved by a valuation allowance.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:12px;text-indent:32px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;ASC 740 further establishes guidance on the accounting for uncertain tax positions. As of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;June&amp;#160;30, 2013&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;, the Company had a liability for uncertain tax positions balance of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$0.07 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;, of which &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$0.05 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; represented unrecognized tax benefits, which if recognized at some point in the future would favorably impact the effective tax rate, and &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$0.02 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; of interest expense. The Company is no longer subject to U.S. federal income tax examinations by tax authorities for the years before &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;2005&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; and state examinations for the years before &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;2003&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;.&lt;/font&gt;&lt;/div&gt;&lt;/div&gt;</NonNumbericText><FootnoteIndexer /><CurrencyCode /><CurrencySymbol /><IsIndependantCurrency>false</IsIndependantCurrency><ShowCurrencySymbol>false</ShowCurrencySymbol><DisplayDateInUSFormat>false</DisplayDateInUSFormat></Cell></Cells><ElementDataType>nonnum:textBlockItemType</ElementDataType><SimpleDataType>na</SimpleDataType><ElementDefenition>The entire disclosure for income taxes.
