Probability of renewal(4)

 

0%

 

 

 

 

 

(1)         NGL prices decrease over the respective periods with increases in the winter months due to seasonality.

 

(2)         The forward ERCOT prices utilized in the valuations are generally flat at the low end of the range with a seasonal spike in pricing in the summer months.

 

(3)         Natural gas prices used in the valuations are generally at the lower end of the range in the early years and increase over time.

 

(4)         The producer counterparty to the embedded derivative has the option to renew the gas purchase agreement and the related keep-whole processing agreement for two successive five year terms after 2022. The embedded gas purchase agreement cannot be renewed without the renewal of the related keep-whole processing agreement. Due to the significant number of years until the renewal options are exercisable and the high level of uncertainty regarding the counterparty’s future business strategy, the future commodity price environment, and the future competitive environment for midstream services in the Appalachia area, management determined that a 0% probability of renewal is an appropriate assumption.
