We allocate net income to our 8.50% Series A, 7.625% Series B and 9.00% Series C Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units (collectively, the Series A, B and C Preferred Units) equal to the amount of distributions earned during the period. Distributions on our Series A, B and C Preferred Units are payable out of any legally available funds, accrue and are cumulative from the original issuance dates, and are payable on the 15th day (or next business day) of each of March, June, September and December of each year to holders of record on the first business day of each payment month as follows (until the distribution rate changes to a floating rate):



Units	Fixed Distribution Rate Per Unit Per Quarter		Fixed Distribution Per Quarter		Date at Which Distribution Rate Becomes Floating
			(Thousands of Dollars)
Series A Preferred Units	$	0.53125	$	4,813	December 15, 2021

Series C Preferred Units	$	0.56250	$	3,881	December 15, 2022

In April 2020, our board of directors declared distributions with respect to the Series A, B and C Preferred Units to be paid on June 15, 2020.

We make quarterly distributions to common unitholders of 100% of our “Available Cash,” generally defined as cash receipts less cash disbursements, including distributions to our preferred units, and cash reserves established by the general partner, in its sole discretion. These quarterly distributions are declared and paid within 45 days subsequent to each quarter-end. The common unitholders receive a distribution each quarter as determined by the board of directors, subject to limitation by the distributions in arrears, if any, on our preferred units.

The following table summarizes information about quarterly cash distributions declared for our common limited partners:
