We recorded a gain of $25.4 million on disposal of property and equipment for the year ended January 3, 2014mainly resulting from the sale of equipment, land and buildings in Canada. This gain was recorded in “Cost of revenues” on our Consolidated Statements of Operations.

Property and equipment was depreciated by using the following estimated useful lives:

	Estimated Useful Lives
Computer software and hardware and other equipment	3 – 10 years
Vehicles and automotive equipment	3 – 12 years
Construction and mining equipment	3 – 15 years
Furniture and fixtures	3 – 10 years
Leasehold improvements (1)	1 – 20 years
Buildings	10 – 45 years

• Leasehold improvements are amortized over the length of the lease or estimated useful life, whichever is less.
