Construction Liabilities

We capitalize construction in progress and record a corresponding long-term liability for certain build-to-suit lease agreements where we are considered the owner during the construction period for accounting purposes, including our Seattle, Washington, corporate office space that we do not currently occupy. See “Note 3—Fixed Assets” for a discussion of these leases.

Tax Contingencies

As of December 31, 2011 and 2010, we have recorded tax reserves for tax contingencies, inclusive of accrued interest and penalties, of approximately $266 million and $243 million for U.S. and foreign income taxes. These contingencies primarily relate to transfer pricing, state income taxes, and research and development credits. See “Note 10—Income Taxes” for discussion of tax contingencies.

The remainder of our long-term liabilities primarily include deferred tax liabilities, unearned revenue, asset retirement obligations, and deferred rental liabilities.
