4. Income Taxes

 

As a limited partnership, we are generally not subject to U.S. federal or state income taxes. Our income tax provision relates primarily to (1) our U.S. corporate subsidiaries that provide services to public utility customers, which may not fit within the definition of qualified income as it is defined in the Internal Revenue Code, Regulations, and other guidance, which subjects this income to U.S. federal and state income taxes, (2) our Canadian subsidiary, which is subject to Canadian federal and provincial income taxes, and (3) certain other state income taxes, including the Texas franchise tax.

 

As a publicly-traded partnership, we are subject to a statutory requirement that 90% of our total gross income represents “qualifying income” (as defined by the Internal Revenue Code, related Treasury Regulations, and Internal Revenue Service pronouncements), determined on a calendar-year basis. If our qualifying income does not meet this statutory requirement, we could be taxed as a corporation for federal and state income tax purposes. Our income has met the statutory qualifying income requirement each year since our initial public offering.
