Accounting
Judgemental itemsCosts may be deferred as assets or liabilities if future recovery/refund is probable, affecting earnings timing.
Impact: Rate-regulated accounting can materially shift expense recognition across periods
Differences between actual gas costs and amounts billed are tracked for later recovery or refund.
Impact: Can create large balance sheet deferrals and volatility in cash flow timing
These mechanisms reduce the direct link between usage volumes and revenue recognition.
Impact: Stabilizes reported margin but adds estimation and regulatory complexity
Infrastructure investments are capitalized and depreciated over time, affecting earnings and rate base.
Impact: Construction spending influences future depreciation and allowed returns
Benefit liabilities depend on actuarial assumptions and funding estimates.
Impact: Changes in discount rates or plan assumptions can affect expense and balance sheet values
