Allocations of Net Income

Our partnership agreement contains provisions for the allocation of net income and loss to the unitholders. For purposes of maintaining partner capital accounts, the partnership agreement specifies that items of income and loss shall be allocated among the partners in accordance with their respective percentage interest. Normal allocations according to percentage interests are made after giving effect, if any, to priority income allocations in an amount equal to incentive cash distributions allocated 100% to SUSS.

The calculation of net income allocated to the partners is as follows (in thousands, except per unit amounts):



Attributable to Common Units
	Year Ended
	December 31, 2012			December 31, 2013
Distributions (a)	$	5,098		$	20,251
Distributions in excess of net income	(523		)	(1,717		)
Limited partners' interest in net income subsequent to initial public offering	$	4,575		$	18,534

Attributable to Subordinated Units
	Year Ended
	December 31, 2012			December 31, 2013
Distributions (a)	$	5,098		$	20,167
Distributions in excess of net income	(523		)	(1,674		)
Limited partners' interest in net income subsequent to initial public offering	$	4,575		$	18,493

(a) Distributions declared per unit to unitholders as of record date	$0.4660			$1.8441

Incentive Distribution Rights

The following table illustrates the percentage allocations of available cash from operating surplus between the unitholders and SUSS (in its capacity as the holder of our incentive distribution rights or "IDRs") based on the specified target distribution levels. The amounts set forth under “marginal percentage interest in distributions” are the percentage interests of SUSS and the unitholders in any available cash from operating surplus we distribute up to and including the corresponding amount in the column “total quarterly distribution per unit target amount”. The percentage interests shown for our unitholders and SUSS for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution. The percentage interests set forth below for SUSS assume that there are no arrearages on common units and that SUSS continues to own all of the IDRs.



			Marginal percentage interest in distributions
	Total quarterly distribution per unit target amount		Unitholders		SUSS
Minimum Quarterly Distribution	$	0.4375	100	%	—
First Target Distribution	Above $0.4375 up to $0.503125		100	%	—
Second Target Distribution	Above $0.503125 up to $0.546875		85	%	15	%
Third Target Distribution	Above $0.546875 up to $0.656250		75	%	25	%
Thereafter	Above $0.656250		50	%	50	%

Cash Distributions

Our partnership agreement, as amended, sets forth the calculation to be used to determine the amount and priority of cash distributions that the common and subordinated unitholders will receive.

The following table presents our cash distributions paid in 2013 and 2012:



Payment Date	Per Unit Distribution		Total Cash Distribution
			( in thousands)
November 29, 2013	$	0.4687	$	10,290
August 29, 2013	$	0.4528	$	9,907
May 30, 2013	$	0.4375	$	9,572
March 1, 2013	$	0.4375	$	9,572
