TYCO INTERNATIONAL LTD.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. Basis of Presentation and Summary of Significant Accounting Policies (Continued)
Gains and losses resulting from foreign currency transactions, including the impact of our foreign
currency derivatives, reflected in selling, general and administrative expenses were $37 million,
$60 million and $77 million in 2008, 2007 and 2006, respectively.
Cash and Cash Equivalents—All highly liquid investments with maturities of three months or less
from the time of purchase are considered to be cash equivalents.
Allowance for Doubtful Accounts—The allowance for doubtful accounts receivable reflects the best
estimate of probable losses inherent in Tyco’s receivable portfolio determined on the basis of historical
experience, specific allowances for known troubled accounts and other currently available evidence.
Inventories—Inventories are recorded at the lower of cost (primarily first-in, first-out) or market
value.
Property, Plant and Equipment, Net—Property, Plant and Equipment, net is recorded at cost less
accumulated depreciation. Depreciation expense for 2008, 2007 and 2006 was $626 million, $635 million
and $663 million, respectively. Maintenance and repair expenditures are charged to expense when
incurred. Except for pooled subscriber systems, depreciation is calculated using the straight-line method
over the estimated useful lives of the related assets as follows:
Buildings and related improvements .... 5 to 50 years
Leasehold improvements ............ Lesser of remaining term of the lease or
economic useful life
Subscriber systems ................. Accelerated method up to 15 years
Other machinery, equipment and
furniture and fixtures ............. 2 to 20 years
See below for discussion of depreciation method and estimated useful lives related to subscriber
systems.
Subscriber System Assets and Related Deferred Revenue Accounts—The Company generally considers
assets related to the acquisition of new customers in its electronic security business in three asset
categories: internally generated residential subscriber systems, internally generated commercial
subscriber systems (collectively referred to as subscriber system assets) and customer accounts acquired
through the ADT dealer program (referred to as dealer intangibles). Subscriber system assets include
installed property, plant and equipment for which Tyco retains ownership and deferred costs directly
related to the customer acquisition and system installation. Subscriber system assets represent
capitalized equipment (e.g. security control panels, touchpad, motion detectors, window sensors, and
other equipment) and installation costs associated with electronic security monitoring arrangements
under which the Company retains ownership of the security system assets in a customer’s residence or
place of business. Installation costs represent costs incurred to prepare the asset for its intended use.
The Company pays property taxes on the subscriber system assets and upon customer termination, may
retrieve such assets. These assets embody a probable future economic benefit as they generate future
monitoring revenue for the Company.
Costs related to the subscriber system equipment and installation are categorized as property, plant
and equipment rather than deferred costs. Deferred costs associated with subscriber system assets
represent direct and incremental selling expenses (i.e. commissions) related to acquiring the customer.
Commissions related to up-front consideration paid by customers in connection with the establishment
