Key money is the amount of funds paid to a landlord or tenant to acquire the rights of tenancy under a commercial property lease for a certain property. Key money represents the “right to lease” with an automatic right of renewal. This right can be subsequently sold by the Company or can be recovered should the landlord refuse to allow the automatic right of renewal to be exercised. Key money is amortized over the initial lease term, which ranges from approximately four to 18 years.

Amortization expense for intangible assets was approximately $3.7 million and $3.8 million for the Second Quarter and Prior Year Quarter, respectively, and $7.4 million and $7.5 million for the Year To Date Period and Prior Year YTD Period, respectively.
