These estimates are based on various factors, including age (in the case of acquired assets), manufacturing specifications, technological advances and historical data concerning useful lives of similar assets. Uncertainties that impact these estimates include changes in laws and regulations relating to restoration and abandonment requirements, economic conditions and supply and demand in the area. When assets are put into service, management makes estimates with respect to useful lives and salvage values that it believes are reasonable. However, subsequent events could cause management to change its estimates, thus impacting the future calculation of depreciation. The Partnership has contractual obligations to perform dismantlement and removal activities in the event that some of its liquid asphalt terminalling assets are abandoned (see Note 15 IMPAIRMENT OF LONG-LIVED ASSETS AND OTHER INTANGIBLE ASSETS not may not not Acquired customer contracts are capitalized and amortized over useful lives ranging from approximately 5 to 10 years using the straight-line method of amortization.
