ONEOK’s interest in OKS
ONEOK increased its ownership in OKS from 37.8% to 41.2%, with additional OKS units purchased in August 2015. OKE’s 41.2% ownership interest includes its 2% GP interest. OKE also holds all the IDRs (incentive distribution rights), which entitles it to receive increasing percentages of incremental cash flows that OKS distributes.
Available cash is distributed to OKS’s general partner (OKE) and limited partners according to their partnership percentages of 2% and 98%, respectively. However, with a quarterly distribution of $0.79 per unit, OKS currently operates in the highest distribution tier.
The IDRs entitle OKE 50% of the amounts distributed in excess of $0.4675 per unit. So, IDRs provide significant leverage to OKE’s cash flow. In periods of no distribution growth, the importance of IDRs becomes relatively reduced.
