A credit balance type concept should always be assigned a negative one (-1) calculation weight as it is a deduction from net income (loss) to reconcile to NetCashProvidedByUsedInOperatingActivities.AssetRetirementObligationCashPaidToSettle has been incorrectly provided a positive one (+1) calculation weight in the extension taxonomy. Correct the calculation weight to negative one (-1) and input the value as a positive amount if it is a deduction of a non-cash income or gain, an increase in an asset, or a decrease in a liability. If the value is an add-back of a non-cash expense or loss, decrease in an asset, or an increase in a liability and AssetRetirementObligationCashPaidToSettle is the correct concept, input a negative value.
