Distributions of Available Cash
General
— Our partnership agreement requires that, within 45 days after the end of each quarter, we
distribute all of our Available Cash (defined below) to unitholders of record on the applicable record date, as
determined by our general partner.
Definition of Available Cash
— Available Cash, for any quarter, consists of all cash and cash equivalents
on hand at the end of that quarter:
• less the amount of cash reserves established by our general partner to:
• provide for the proper conduct of our business;
• comply with applicable law, any of our debt instruments or other agreements; or
• provide funds for distributions to our unitholders and to our general partner for any one or more of the
next four quarters;
• plus, if our general partner so determines, all or a portion of cash and cash equivalents on hand on the
date of determination of Available Cash for the quarter.
Minimum Quarterly Distribution
— The Minimum Quarterly Distribution, as set forth in the partnership
agreement, is $0.35 per unit per quarter, or $1.40 per unit per year. Our current quarterly distribution is $0.65
per unit, or $2.60 per unit annualized. There is no guarantee that we will maintain our current distribution or
pay the Minimum Quarterly Distribution on the units in any quarter. Even if our cash distribution policy is not
modified or revoked, the amount of distributions paid under our policy and the decision to make any
distribution is determined by our general partner, taking into consideration the terms of our partnership
agreement. Please read “Management’s Discussion and Analysis of Financial Condition and Results of
Operations — Capital Requirements — Description of Credit Agreement” for a discussion of the restrictions
included in our credit agreement that may restrict our ability to make distributions.
General Partner Interest and Incentive Distribution Rights
— As of December 31, 2011, the general
partner is entitled to a percentage of all quarterly distributions equal to its general partner interest of
