Long-Lived Assets

The Company evaluates the recoverability of its long-lived assets, which include property and equipment, broadcasting licenses (subject to an eight-year renewal cycle), goodwill, deferred charges, and other assets. See Note 2 for further discussion. The determination and measurement of the fair value of long-lived assets requires the use of significant judgments and estimates. Future events may impact these judgments and estimates.

During the second quarter of 2013, the Company conducted an evaluation of useful lives for longer-lived assets, such as broadcast towers and buildings. As a result of this review, the Company determined that based on current facts and circumstances, future acquisitions may warrant the use of longer lives anywhere between 15 years and 40 years.

Recent Accounting Pronouncements

The Company does not believe that any recently issued pronouncements, including those listed below, would have a material effect on the Company's results of operations, cash flows or financial condition.

Netting Of Unrecognized Tax Benefits Against Tax Assets

In June 2013, the accounting guidance was modified to require the netting of unrecognized tax benefits against a deferred tax asset for a loss or other carryforward that would apply in the settlement of uncertain tax positions. This guidance is effective for the Company beginning January 1, 2014 and can be applied on a prospective basis. The Company does not anticipate that the adoption of this guidance will have a material effect on the presentation of the Company's consolidated financial statements as the Company's current presentation conforms to this new guidance.

Entities are required to provide both net and gross information for these assets and liabilities in order to provide for comparability with international accounting standards. This guidance, which was effective for the Company as of January 1, 2013, did not have a material effect on the presentation of the Company's consolidated financial statements.
