All of the annual income, gains, losses, deductions or credits flow through the partnership to the unitholders on a per unit basis. · Proven track record of executing growth strategy — Rapid expansion since the Company’s formation in 1968 — Completed $6 billion merger with GulfTerra Energy Partners, L.P. in September 2004 (includes $2 billion of debt assumed and refinanced) — Expect to generate new cash flows in 2009 and 2010 from approximately $2.6 billion of growth capital projects put in service in late 2008 and 2009. — Low cost of capital relative to peers The unitholders are required to report their allocated share of these amounts on their income tax returns whether or not any cash distributions are paid by the partnership. · Cash distributions paid by a partnership to a unitholder are generally not taxable, unless the amount of any cash distributed is in excess of the unitholder’s adjusted basis in his partnership interest. · Generally in late February, Enterprise provides each unitholder a Schedule K-1 tax package that includes each unitholder’s allocated share of reportable · History of increasing cash distributions leading to superior attractive total returns which reduces cost of equity capital · Attractive yield and tax deferral · Management team with interests aligned with the public partners — Management and their affiliates own approximately 35 percent of the limited partner units outstanding · General Partner’s incentive distribution rights are capped at 25 percent compared to 50 percent for most other publicly traded partnerships partnership items and other partnership information necessary to complete their income tax returns. The K-1 provides a unitholder the required tax information for their ownership interest in the partnership, just as a Form 1099-DIV does for a stockholder’s ownership interest in a corporation.
