Concentrations of Credit Risk

12 Months Ended

Jun. 30, 2017

Major Customers. Historically we market all of our oil and natural gas production from the properties we operate. We do not currently market our share of crude oil and NGL production from Delhi. Although we have the right to take our working interest production at Delhi in-kind, we are currently selling our production under the Delhi operator's agreement with Plains Marketing L.P. and American Midstream for the sale of our oil and NGL's, respectively at the field. The majority of our operated gas, oil and condensate production is sold to purchasers under short-term (less than 12 months) contracts at market-based prices. The following table identifies customers from whom we derived 10 percent or more of our net oil and natural gas revenues during the years ended June 30, 2017, 2016, and 2015. The loss of our purchasers at the Delhi field or disruption to pipeline transportation from the field could adversely affect our net realized pricing and potentially our near-term production levels.

Accounts Receivable. Substantially all of our accounts receivable result from oil and natural gas sales to third parties in the oil and natural gas industry. Our concentration of customers in this industry may impact our overall credit risk.

Cash and Cash Equivalents and Certificates of Deposit. We are subject to concentrations of credit risk with respect to our cash and cash equivalents, which we attempt to minimize by maintaining our cash and cash equivalents in high quality money market funds.
