It's all there in black and white. $207M in debt retirement gains from July alone. As far as derivative gains, the following occurred last qtr: WTI spot went from $48 to $60 and Linn recorded a loss of almost $200M. With WTI going from $60 to its current $39 (who knows on Sept30 tho), the prorated gain approaches $300M.
Linn's preadjustment earnings Q3 are going to be BIG. $300M+ gain on retirement of debt and $300M+ on increase in derivative valuation. That's $600M for the quarter - plus whatever they make operationally. Even more if they take advantage of the 60% discount to buy even more debt.
