CHK royalty check for 04/14 shows adjustments for 9/13-12/13 with GAS up in volume & price& NGL down in volume & price.  The first numbers for Gas(2) were my original, the second numbers are my adjustment. Same for NGL(4) original top, adjustment bottom.  My question is do you know why this occurs. CHK gave no explanation. Thank you for input.
