A portion of the Company’s customer relationships is held in functional currencies outside the U.S. Therefore, the stated cost as well as the accumulated amortization is affected by the fluctuation in foreign currency exchange rates.

The weighted average life for below market leasehold interests has changed to 8 years as of August 31, 2013 from 6 years as of May 31, 2013 as a result of the renewal of certain lease agreements which extended the lease terms of existing leases. The costs associated with the new leases were treated as operating expenses as incurred.

Amortization expense related to these intangible assets for the three months ended August 31, 2013 and August 31, 2012 was $13.2 million and $12.4 million, respectively. Expected amortization expense for the remainder of fiscal 2014 and for each of the five succeeding years is as follows (in thousands):

2014	39,684
2015	52,905
2016	52,869
