The Company's indefinite-lived intangible assets consist of Federal Communications Commission (“FCC”) broadcast licenses in its Media and Entertainment (“CCME”) segment and billboard permits in its Americas outdoor advertising segment. Due to significant differences in both business practices and regulations, billboards in the International outdoor advertising segment are subject to long-term, finite contracts unlike the Company's permits in the United States and Canada. Accordingly, there are no indefinite-lived intangible assets in the International outdoor advertising segment.

Other intangible assets include definite-lived intangible assets and permanent easements. The Company's definite-lived intangible assets include primarily transit and street furniture contracts, talent and representation contracts, customer and advertiser relationships, and site-leases, all of which are amortized over the respective lives of the agreements, or over the period of time the assets are expected to contribute directly or indirectly to the Company's future cash flows. Permanent easements are indefinite-lived intangible assets which include certain rights to use real property not owned by the Company. The Company periodically reviews the appropriateness of the amortization periods related to its definite-lived intangible assets. These assets are recorded at cost.

The following table presents the gross carrying amount and accumulated amortization for each major class of other intangible assets at June 30, 2014 and December 31, 2013, respectively:
