TAC. TAC consist of payments made to third-party entities that have integrated our advertising offerings into
their Websites or other offerings and payments made to companies that direct consumer and business traffic to
Yahoo! Properties. We enter into agreements of varying duration that involve TAC. There are generally two
economic structures of the Affiliate agreements: fixed payments based on a guaranteed minimum amount of
traffic delivered, which often carry reciprocal performance guarantees from the Affiliate, or variable payments
based on a percentage of our revenue or based on a certain metric, such as number of searches or paid clicks. We
expense TAC under two different methods. Agreements with fixed payments are expensed ratably over the term
the fixed payment covers, and agreements based on a percentage of revenue, number of searches, or other metrics
are expensed based on the volume of the underlying activity or revenue multiplied by the agreed-upon price or
rate.
Compensation, Information Technology, Depreciation and Amortization, and Facilities Expenses. Compensation
expense consists primarily of salary, bonuses, commissions, and stock-based compensation expense. Information
and technology expense includes telecom usage charges and data center operating costs. Depreciation and
amortization expense consists primarily of depreciation of server equipment and information technology assets
and amortization of developed or acquired technology and intellectual property rights. Facilities expense consists
primarily of building maintenance costs, rent expense, and utilities.
