Pennsylvania-based Rex Energy has a new chief financial officer: Curt Walker, Kallanish Energy reports. He was promoted internally after the existing CFO quit after three years. The BDC Credit Reporter cannot tell if this is a worrisome development or not, as no reasons are given for the sudden departure of the CFO. TSLX has a $15.1mn Senior Secured position at 9/30/2017, which is carried at par. No impact likely.
