PostRock Announces Borrowing Base Lowered To $200M From $225M

PostRock Energy Corporation PSTR today announced its lenders have completed their scheduled borrowing base redetermination. The redetermination was based on the value of PostRock's oil and gas reserves at March 31, 2011 under lender pricing assumptions. Primarily as a result of the decline in lender natural gas price assumptions and the roll off of natural gas hedges since the Company's last redetermination, the Borrowing Base was lowered to $200 million from $225 million.
