Distributions

Series A Preferred Unit Distributions. After the fifth anniversary of the January 28, 2016 issuance date of our Series A preferred units, the holders of our Series A preferred units, acting by majority vote, had the option to make a one-time election to reset the Series A preferred unit distribution rate to equal the then applicable rate of ten-year U.S. Treasury Securities plus 5.85% (the “Preferred Distribution Rate Reset Option”). In January 2023, the Series A preferred unitholders elected the Preferred Distribution Rate Reset Option which resulted in an increase in the quarterly distribution rate to approximately $0.615 per unit. This new distribution rate was effective on January 31, 2023. The quarterly distribution paid in May 2023 reflected a pro-rated amount of approximately $0.585 per unit. The following table details distributions to our Series A preferred unitholders paid during or pertaining to the first six months of 2023 (in millions, except per unit data):
