Notional Amounts - As of September 30, 2022, gross notional amounts and settlement/delivery years related to outstanding swap contracts, option contracts, physical forward contracts and FTRs that were accounted for as commodity derivative instruments were as follows (units in thousands):


	Electricity		FTRs		Natural Gas		Coal		Diesel Fuel
	MWhs	Years	MWhs	Years	Dths	Years	Tons	Years	Gallons	Years
Alliant Energy	1,379	2022-2024	14,454	2022-2023	249,508	2022-2032	1,566	2022-2023	756	2022
IPL	768	2022-2024	6,165	2022-2023	135,193	2022-2030	669	2022-2023	—	—
WPL	611	2022-2023	8,289	2022-2023	114,315	2022-2032	897	2022-2023	756	2022

Financial Statement Presentation - Derivative instruments are recorded at fair value each reporting date on the balance sheets as assets or liabilities as follows (in millions):


	Alliant Energy		IPL		WPL
	September 30, 2022	December 31, 2021	September 30, 2022	December 31, 2021	September 30, 2022	December 31, 2021
Current derivative assets	$200	$113	$117	$48	$83	$65
Non-current derivative assets	160	63	85	36	75	27
Current derivative liabilities	71	8	54	4	17	4
Non-current derivative liabilities	27	1	12	—	15	1

During the nine months ended September 30, 2022, Alliant Energy’s, IPL’s and WPL’s derivative assets increased primarily due to the annual FTR auction operated by MISO and as a result of higher natural gas prices. Alliant Energy’s, IPL’s and WPL’s derivative liabilities increased primarily due to new natural gas contracts entered into in the second quarter of 2022. Based on IPL’s and WPL’s cost recovery mechanisms, the changes in the fair value of derivative liabilities/assets resulted in comparable changes to regulatory assets/liabilities on the balance sheets.

Credit Risk-related Contingent Features - Various agreements contain credit risk-related contingent features, including requirements to maintain certain credit ratings and/or limitations on liability positions under the agreements based on credit ratings. Certain of these agreements with credit risk-related contingency features are accounted for as derivative instruments. In the event of a material change in creditworthiness or if liability positions exceed certain contractual limits, credit support may need to be provided up to the amount of exposure under the contracts, or the contracts may need to be unwound and underlying liability positions paid. At September 30, 2022 and December 31, 2021, the aggregate fair value of all derivative instruments with credit risk-related contingent features in a net liability position was not materially different than amounts that would be required to be posted as credit support to counterparties by Alliant Energy, IPL or WPL if the most restrictive credit risk-related contingent features for derivative agreements in a net liability position were triggered.

Balance Sheet Offsetting - The fair value amounts of derivative instruments subject to a master netting arrangement are not netted by counterparty on the balance sheets. However, if the fair value amounts of derivative instruments by counterparty were netted, derivative assets and derivative liabilities related to commodity contracts would have been presented on the balance sheets as follows (in millions):


	Alliant Energy		IPL		WPL
	Gross		Gross		Gross
	(as reported)	Net	(as reported)	Net	(as reported)	Net
September 30, 2022
Derivative assets	$360	$308	$202	$165	$158	$143
Derivative liabilities	98	46	66	29	32	17
December 31, 2021
Derivative assets	176	171	84	83	92	88
Derivative liabilities	9	4	4	3	5	1

Fair value amounts recognized for the right to reclaim cash collateral (receivable) or the obligation to return cash collateral (payable) are not offset against fair value amounts recognized for derivative instruments executed with the same counterparty under the same master netting arrangement.
