9. INCOME TAXES

Series II operates so that it will qualify to be treated as a partnership for U.S. federal income tax purposes under the Internal Revenue Code of 1986, as amended, and not as a publicly traded partnership taxable as a corporation. As such, it will not be subject to any U.S. federal and state income taxes.

Series II holds certain equity investments in taxable subsidiaries (the “Taxable Subsidiaries”). The Taxable Subsidiaries permit Series II to hold equity investments in Infrastructure Assets which are “pass through” entities for tax purposes. The Taxable Subsidiaries are not consolidated with Series II for income tax purposes and may generate income tax expense, or benefit, and the related tax assets and liabilities, as a result of the Taxable Subsidiaries’ ownership of certain Infrastructure Assets in the United States.

Series II considers, among other things, the generation of future taxable income (including reversals of deferred tax assets) during the periods in which the related temporary differences will become deductible.
