(a)
|
Includes payments required by PPAs for capacity rights and minimum quantities of MWhs required to be purchased. As a result of an amendment to shorten the term of the DAEC PPA, Alliant Energy’s and IPL’s amounts include minimum future commitments related to IPL’s purchase of capacity and the resulting energy from DAEC through September 2020, and do not include the September 2020 buyout payment of $110 million.
|
(b)
|
Corporate Services entered into system-wide coal contracts on behalf of IPL and WPL that include minimum future commitments. These commitments were assigned to IPL and WPL based on information available as of September 30, 2019 regarding expected future usage, which is subject to change.
|
(c)
|
Includes individual commitments incurred during the normal course of business that exceeded $1 million at September 30, 2019.

In March 2019, IPL filed requests with the IUB to increase annual base rates for its Iowa retail electric and gas customers, which were based on a forward-looking test period that includes 2020. IPL concurrently filed for interim retail electric rates based on a 2018 historical Test Year, which were implemented effective April 1, 2019. In October 2019, IPL reached settlement agreements with intervenor groups for annual retail electric and gas base rate increases. The electric base rate agreement includes a return on common equity of 9.5% for all non-advanced rate making principle generating assets and 5% for production tax credit carryforwards for the most recent 1,000 MW of new wind generation development, recovery of the most recent 1,000 MW of new wind generation development through a new renewable energy rider, and a 51% common equity component of regulatory capital structure. The gas base rate agreement includes a return on common equity of 9.6% and a 51% common equity component of regulatory capital structure. Refer to Note 2 for details.

|
In March 2019, the IUB approved IPL’s energy efficiency plan for 2019 through 2023, which provides direct financial savings to customers and provides cost-effective options to help electric and gas customers reduce their energy usage. The energy efficiency costs, which are lower than previous energy efficiency plans, are reflected on electric and gas customer bills beginning June 2019 and November 2019, respectively.

|
In January and March 2019, AEF, a subsidiary of Alliant Energy, purchased two freight management companies. These non-utility acquisitions enhance Alliant Energy’s Transportation value to customers by adding customized supply chain solution capabilities to their portfolio of service offerings. Refer to Note 4 for details.

In April 2019, IPL issued $300 million of 3.60% senior debentures due 2029. In September 2019, IPL issued $300 million of 3.50% senior debentures due 2049. The senior debentures were issued as green bonds, and all of the net proceeds have been or will be allocated for the construction and development of IPL’s wind projects.
|
•
|
In June 2019, WPL issued $350 million of 3.00% debentures due 2029. The net proceeds from the issuance were used by WPL to reduce its outstanding commercial paper and retire its $250 million 5% debentures that matured in July 2019.

IPL’s interim retail electric base rate increase effective April 1, 2019 was reduced by anticipated production tax credits for IPL’s new wind generation placed in service in March 2019. This reduction in revenue requirement is expected to be offset by a reduction in income tax expense resulting from production tax credits recognized from the new wind generation. Additionally, the interim retail electric base rate increase was reduced by $8 million as a result of the partial refund agreed to as part of the rate review proposed settlement. Refer to Note 2 for further discussion.

Financing Plans - Alliant Energy currently expects to issue up to $250 million of common stock in 2020 through one or more offerings and its Shareowner Direct Plan. IPL, WPL and AEF currently expect to issue up to $300 million, $350 million and $300 million of long-term debt in 2020, respectively. IPL, WPL and AEF have $200 million, $150 million and $300 million of long-term debt maturing in 2020, respectively.
|
•
|
Common Stock Dividends - Alliant Energy announced a 7% increase in its targeted 2020 annual common stock dividend to $1.52 per share, which is equivalent to a quarterly rate of $0.38 per share, beginning with the February 2020 dividend payment. The timing and amount of future dividends is subject to an approved dividend declaration from Alliant Energy’s Board of Directors, and is dependent upon earnings expectations, capital requirements, and general financial business conditions, among other factors.
|
•
|
Higher Earnings on Increasing Rate Base - Alliant Energy and IPL currently expect an increase in earnings in 2020 compared to 2019 due to impacts from increasing revenue requirements from IPL’s retail electric and gas rate reviews (2020 Forward-looking Test Period). IPL’s and WPL’s 2020 increased revenue requirements are expected to be offset by returning to customers a portion of the excess deferred income tax credits from Federal Tax Reform.
|
•
|
Depreciation and Amortization Expenses - Alliant Energy, IPL and WPL currently expect an increase in depreciation and amortization expenses in 2020 compared to 2019 due to property additions, including IPL’s expansion of wind generation and WPL’s West Riverside natural gas-fired EGU.
|
•
|
Interest Expense - Alliant Energy currently expects interest expense to increase in 2020 compared to 2019 primarily due to financings completed in 2019 and planned in 2020 as discussed above.
|
•
|
Allowance for Funds Used During Construction - Alliant Energy currently expects allowance for funds used during construction to decrease in 2020 compared to 2019 primarily due to decreased construction work in progress balances related to IPL’s wind generation that was placed in service in 2019 and is expected to be placed in service in 2020, and WPL’s West Riverside Energy Center, which is currently expected to be placed in service by the end of 2019.

The registrant’s other certifying officer(s) and I are responsible for establishing and maintaining disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and have:
|
a)
|
Designed such disclosure controls and procedures, or caused such disclosure controls and procedures to be designed under our supervision, to ensure that material information relating to the registrant, including its consolidated subsidiaries, is made known to us by others within those entities, particularly during the period in which this report is being prepared;
|
b)
|
Designed such internal control over financial reporting, or caused such internal control over financial reporting to be designed under our supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles;

Disclosed in this report any change in the registrant’s internal control over financial reporting that occurred during the registrant’s most recent fiscal quarter (the registrant’s fourth fiscal quarter in the case of an annual report) that has materially affected, or is reasonably likely to materially affect, the registrant’s internal control over financial reporting; and
|
5.
|
The registrant’s other certifying officer(s) and I have disclosed, based on our most recent evaluation of internal control over financial reporting, to the registrant’s auditors and the audit committee of the registrant’s board of directors (or persons performing the equivalent functions):
|
a)
|
All significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are reasonably likely to adversely affect the registrant’s ability to record, process, summarize and report financial information; and
