AMEREN TRANSMISSION COMPANY OF ILLINOIS
NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2022 and 2021
Basis of Accounting

Accounting policies for regulated operations are in accordance with those prescribed by the regulatory authorities having jurisdiction, principally the Illinois Commerce Commission (ICC), the Federal Energy Regulatory Commission (FERC) and the Securities and Exchange Commission (SEC) under the Public Utility Holding Company Act of 2005 (PUHCA). The accompanying financial statements have been prepared in accordance with the accounting requirements of the FERC as set forth in the Uniform System of Accounts (USOA) and accounting releases, which require certain differences from accounting principles generally accepted in the United States (GAAP). The differences between the accounting requirements of FERC and GAAP include, but are not limited to, the following:

a.Balance sheet presentation of asset removal costs, accumulated deferred income taxes, uncertain tax positions, property, plant and equipment, regulatory assets, and regulatory liabilities.
b.Income statement classification of certain items between operating revenues and expenses and nonoperating revenues and expenses, including the non-service cost or income components of the net periodic benefit cost related to pensions and other postretirement benefit plans.
c.Cash flow statement classification for restricted cash and implementation costs for cloud computing.

NOTE 1 NATURE OF OPERATIONS
ATXI is a wholly owned subsidiary of Ameren that constructs, acquires, and operates electric transmission assets, and is a transmission owner within the MISO. ATXI’s transmission rates are determined in accordance with the MISO tariff. ATXI operates the Illinois Rivers transmission line, a 345-kilovolt electric transmission line connecting eastern Missouri to western Indiana, the Spoon River transmission line, a 345-kilovolt line located in northwest Illinois, and the Mark Twain transmission line, a 345-kilovolt line located in northeast Missouri that connects Iowa to the Illinois Rivers transmission line. See Note 3 – Rate and Regulatory Matters for additional information regarding ATXI’s ratemaking framework and transmission rate incentives. As ATXI has no employees, it outsources the construction, maintenance, and operation of its electric transmission assets, including through the use of services from affiliated companies. See Note 8 – Related-party Transactions for a description of affiliate agreements.
ATXI’s rate-regulated revenues are primarily derived from sales of transmission service, with the MISO acting as a billing agent for these revenues. As a result, ATXI’s trade accounts receivable balances at December 31, 2022 and 2021, primarily represented receivable balances due from the MISO.
NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
General
ATXI’s accounting policies conform to GAAP. The financial statements reflect all adjustments (which include normal, recurring adjustments) that are necessary, in ATXI’s opinion, for a fair presentation of ATXI’s results. The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions. Such estimates and assumptions affect reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the dates of financial statements, and the reported amounts of revenues and expenses during the reported periods. Actual results could differ from those estimates.
Regulation
The rates that ATXI is allowed to charge for its electric transmission services significantly influence its results of operations, its financial position, and its liquidity. The electric utility industry is highly regulated. The electric transmission rates charged to customers and various other matters are determined by the FERC. Decisions made by the FERC regarding rates are largely outside of ATXI’s control. These decisions could have a material effect on ATXI’s results of operations, its financial position, and its liquidity. ATXI defers certain costs as regulatory assets pursuant to actions of the FERC or because of expectations that it will be able to recover such costs in future rates charged to customers. ATXI also defers certain amounts as regulatory liabilities pursuant to actions of the FERC or based on the expectation that such amounts will be refunded to customers in future rates. Regulatory assets and liabilities are amortized consistent with the period of expected regulatory treatment. ATXI continually assesses the recoverability of its regulatory assets. Regulatory assets are charged to earnings when it is no longer probable that such amounts will be recovered through future revenues. To the extent that reductions in customers rates or refunds to customers related to regulatory liabilities are no longer probable, the amounts are credited to earnings. See Note 3 – Rate and Regulatory Matters for additional information regarding ATXI’s regulatory framework and regulatory assets and liabilities recorded at December 31, 2022 and 2021.
The MoPSC and the ICC regulate certain non-rate utility matters for ATXI. ATXI does not have retail distribution customers; therefore, the MoPSC and the ICC do not have authority to regulate its rates. Under the Public Utility Holding Company Act of 2005, the FERC and each state public utility regulatory agency in the states in which ATXI operates may access its books and records that are found to be relevant to costs incurred by ATXI that may affect jurisdictional rates.
ATXI must receive FERC approval to enter into various transactions, such as issuing short-term debt securities and conducting certain acquisitions, mergers, and consolidations. In addition, ATXI must receive authorization from the applicable state public utility regulatory agencies to issue stock and long-term debt securities, sell utility assets, enter into affiliate transactions, and for various other activities.
ATXI is also subject to mandatory reliability standards, including cybersecurity standards adopted by the FERC, to ensure the reliability of the bulk electric power system. These standards are developed and enforced by the NERC, pursuant to authority delegated to it by the FERC. ATXI is a member of the SERC. The SERC is one of six regional entities representing all or portions of 16 central and southeastern states under authority from the NERC for the purpose of implementing and enforcing reliability standards approved by the FERC. The regional entities of the NERC work to safeguard the reliability of the bulk power systems throughout North America. If ATXI is found not to be in compliance with these mandatory reliability standards, it could incur substantial monetary penalties and other sanctions.
Cash and Cash Equivalents
Cash and cash equivalents include short-term, highly liquid investments purchased with an original maturity of three months or less.
Property, Plant, and Equipment, Net
ATXI capitalizes the cost of additions to, and betterments of, units of property, plant and equipment. The cost includes labor, material, applicable taxes, and overhead. Maintenance expenditures are expensed as incurred. When units of depreciable property are retired, the original costs, and the associated removal cost, net of salvage, are charged to accumulated depreciation. See Note 4 – Property, Plant, and Equipment, Net for additional information.
Depreciation
Depreciation is provided over the estimated lives of the various classes of depreciable property by applying composite rates on a straight-line basis to the cost basis of such property. The composite rates include a provision for the estimated removal cost of property, plant, and equipment retired from service, net of salvage. The provision for depreciation in 2022 and 2021 was approximately 2% of the average depreciable cost.
Operating Revenues
ATXI’s electric transmission service operating revenues are regulated by the FERC. See Note 3 – Rate and Regulatory Matters for information regarding ATXI’s formula rate framework.
Electric transmission revenues are earned as electric transmission services are provided. Revenues from contracts with customers are equal to the amounts billed at the end of each accounting period. Revenues are billed at least monthly, and payments are due less
than one month after services are provided. For revenue requirement reconciliation adjustments, which are considered revenues from alternative revenue programs rather than revenues from contracts with customers, ATXI recognizes revenues that have been authorized for rate recovery, are objectively determinable and probable of recovery, and are expected to be collected from customers within two years from the end of the year. These revenues are subsequently recognized as revenues from contracts with customers when billed, with an offset to revenues from alternative revenue programs.
Income Taxes
ATXI uses an asset and liability approach for its financial accounting and reporting of income taxes. Deferred tax assets and liabilities are recognized for transactions that are treated differently for financial reporting and income tax return purposes. These deferred tax assets and liabilities are based on statutory tax rates. In accordance with USOA, we report deferred income tax balances arising from temporary differences in Accounts 190, 282, 283 as appropriate, which differs from the net presentation required by GAAP.
ATXI expects that the FERC will reduce future revenues for deferred tax liabilities that were initially recorded at rates in excess of the current statutory rate. Therefore, reductions in certain deferred tax liabilities that were recorded because of a decrease in the federal statutory rate have been credited to a regulatory liability. A regulatory asset has been established to recognize the probable recovery through future customer rates for the effects of tax rate increases. To the extent deferred tax balances are included in rate base, the revaluation of deferred taxes is recorded as a regulatory asset or liability on the balance sheet and will be collected from, or refunded to, customers.
ATXI and all other Ameren subsidiary companies are parties to a tax allocation agreement with Ameren (parent) that provides for the allocation of consolidated tax liabilities. The tax allocation agreement specifies that each subsidiary be allocated an amount of tax using a stand-alone calculation ratio to the total amount of tax owed by the consolidated group. Any net benefit attributable to Ameren (parent) is reallocated to the other subsidiaries. This reallocation is treated as a capital contribution to the subsidiary receiving the benefit.
Subsequent Events
ATXI has evaluated subsequent events for potential recognition and disclosure through April 6, 2023, the date the financial statements were issued. From January 1, 2023 through April 6, 2023, there were no subsequent events that required recognition in the accompanying financial statements.
NOTE 3 – RATE AND REGULATORY MATTERS
ATXI is a transmission owner in the AMMO and AMIL pricing zones, providing transmission service under the MISO Open Access Transmission, Energy, and Operating Reserve Markets tariff in those pricing zones. ATXI has received FERC approval to use a company-specific, forward-looking formula ratemaking framework in setting its transmission rates. These forward-looking rates are updated annually and become effective each January with forecasted information. The formula rate framework provides for an annual reconciliation of the electric transmission service revenue requirement, which reflects the actual recoverable costs incurred and the 13-month average rate base for a given year, with the revenue requirement in customer rates, including an allowed ROE. If a given year’s revenue requirement varies from the amount collected from customers, an adjustment is made to electric operating revenues with an offset to a regulatory asset or liability to reflect that year’s actual revenue requirement, independent of actual sales volumes. The regulatory balance is collected from, or refunded to, customers within two years from the end of the year. FERC revenue requirement reconciliation adjustment regulatory assets earn carrying costs at ATXI’s short-term interest rate, while ATXI incurs interest at a FERC-prescribed rate on related regulatory liabilities. The FERC has approved an incentive adder of up to 50 basis points on the allowed base ROE for ATXI’s participation in an RTO, and an additional 50 basis point ROE incentive adder for the Mark Twain transmission line based on the unique nature of the risks involved in the transmission line.
FERC Complaint Cases
Since November 2013, the allowed base ROE for FERC-regulated transmission rate base under the MISO tariff has been subject to customer complaint cases and has been changed by various FERC orders. In May 2020, the FERC issued an order, which set the allowed base ROE to 10.02%, and required refunds, with interest, for the periods November 2013 to February 2015 and from late September 2016 forward. ATXI paid these refunds, including interest, by March 31, 2022. In June and July 2020, ATXI, as well as various customers, petitioned the United States Court of Appeals for the District of Columbia Circuit for review of the May 2020 order, challenging certain aspects of the new ROE methodology established. The petition filed by ATXI challenged the refunds required for the period from September 2016 to May 2020. In August 2022, the court issued a ruling that granted the customers’ petition for review, vacated the FERC’s previous MISO ROE-determining orders, and remanded the proceedings to the FERC. The court did not rule on the petition filed by ATXI. The currently allowed base ROE of 10.02% will remain effective for customer billings, but subject to refund if the base ROE is changed by the FERC in a future order. The FERC is under no deadline to issue an order related to these proceedings. A 50 basis point change in the FERC-allowed ROE would affect ATXI’s annual revenue by an estimated $6 million based on its 2023 projected rate base.
Regulatory Assets and Liabilities
The following table presents regulatory assets and regulatory liabilities in accordance with GAAP authoritative guidance at December 31, 2022 and 2021:

NOTE 5 – SHORT-TERM DEBT AND LIQUIDITY
Money Pool
Ameren has a utility money pool agreement with and among its subsidiaries to coordinate and provide for certain short-term cash and working capital requirements. The money pool agreement may be terminated upon mutual agreement by Ameren and its subsidiaries. Ameren Missouri, Ameren Illinois, and ATXI may participate in the utility money pool as both lenders and borrowers. Ameren (parent) and Ameren Services may participate in the utility money pool only as lenders. Surplus internal funds are contributed to the money pool by participants. The primary sources of external funds for the utility money pool are credit agreements and commercial paper programs at certain participants. The total amount available to the pool participants from the money pool at any given time is reduced by the amount of borrowings made by participants, but is increased to the extent that the pool participants advance surplus funds to the money pool or remit funds from other external sources. The availability of funds is also determined by funding requirement limits established by regulatory authorizations. Participants receiving a loan under the money pool agreement must repay the principal amount of such loan, together with accrued interest, on demand and, in any event, within one year of the date on which such loan was made. The rate of interest depends on the composition of internal and external funds in the utility money pool. The average interest rates for borrowing under the utility money pool were 1.95% and 0.17% for the years ended December 31, 2022 and 2021, respectively.
In 2022, the use of cash provided by operating and financing activities to fund capital expenditures and other long-term investments and to repay then-outstanding short-term and long-term debt resulted in a working capital deficit, defined as current liabilities exceeding current assets. The working capital deficit as of December 31, 2022, was the result of affiliate borrowings. ATXI has the ability to access funding from the money pool agreement up to a $300 million limit, pursuant to FERC authorization effective through January 2025. The amount of ATXI money pool borrowings outstanding at December 31, 2022 and 2021, was $15 million and $77 million, respectively. At December 31, 2022, ATXI could have borrowed up to an additional $285 million under the money pool. See Note 8 – Related-party Transactions for the amount of interest expense from money pool borrowings recorded by ATXI for the years ended December 31, 2022 and 2021.
NOTE 6 – LONG-TERM DEBT AND NOTE PAYABLE TO AMEREN
In 2017, pursuant to a note purchase agreement, ATXI issued $450 million principal amount of 3.43% senior unsecured notes due 2050.
In November 2021, pursuant to a note purchase agreement, ATXI agreed to issue $95 million of its 2.96% senior unsecured notes due August 2052, with interest payable semiannually on February 25 and August 25 of each year, beginning February 25, 2023, through a private placement offering exempt from registration under the Securities Act of 1933, as amended. In August 2022, ATXI issued the notes and received net proceeds of $95 million, which were used to refinance the remaining portion of an intercompany long-term note with Ameren (parent), repay a $50 million principal payment of its 3.43% senior unsecured notes in August 2022, and to repay short-term debt.
In November 2021, pursuant to a note purchase agreement, ATXI issued $75 million of its 2.45% senior unsecured notes due November 2036, with interest payable semiannually on May 16 and November 16 of each year, beginning May 16, 2022, through a private placement offering exempt from registration under the Securities Act of 1933, as amended. ATXI received net proceeds of $75 million, which were used to refinance a portion of an intercompany long-term note with Ameren (parent) and to repay short-term debt.

The note purchase agreements includes financial covenants that require ATXI to not permit at any time: (1) debt to exceed 70% of total capitalization or (2) secured debt to exceed 10% of total assets. The note purchase agreements also contain restrictive covenants that, among other things, restrict the ability of ATXI to: (1) enter into certain transactions with affiliates; (2) consolidate, merge, transfer or lease all or substantially all of its assets; and (3) create liens. At December 31, 2022, ATXI was in compliance with the provisions and covenants contained in its note purchase agreements.
In August 2022, ATXI repaid $35 million of the remaining portion of a 3.65% promissory note due 2025, which was issued under a long-term borrowing agreement with Ameren in 2015, with the proceeds from the issuance of the 2.96% senior unsecured notes due 2052. In 2021, ATXI repaid $40 million of the promissory note with the proceeds from November 2021 2.45% senior unsecured notes issuance. Per the terms of the long-term borrowing agreement with Ameren, these prepayments did not include any penalties or premiums.
Off-balance-sheet Arrangements
At December 31, 2022 and 2021, ATXI did not have any significant off-balance-sheet financing arrangements.

Uncertain Tax Positions
As of December 31, 2022 and 2021, ATXI had not recorded any uncertain tax positions.
Ameren is a part of the IRS’s compliance assurance process program, which involves real-time review of compliance with federal income tax law. State income tax returns are generally subject to examination for a period of three years after filing. The state impact of any federal changes remains subject to examination by various states for up to one year after formal notification to the states. Ameren’s federal tax returns for the 2019, 2020, 2021, and 2022 tax years are open, but, at the time of this filing, ATXI does not have material income tax issues under examination, administrative appeals, or litigation.
NOTE 8 – RELATED-PARTY TRANSACTIONS
In the normal course of business, ATXI has engaged in, and may in the future engage in, affiliate transactions. These transactions primarily consist of services received or rendered, and borrowings and lendings. Transactions between affiliates are reported as affiliate transactions on ATXI’s financial statements. Below are the material related-party agreements.
Interconnection Agreement
ATXI and Ameren Missouri are parties to an interconnection agreement that governs the connection of the High Prairie Renewable Energy Center, a 400-megawatt wind generation facility owned and operated by Ameren Missouri, to an ATXI transmission line that allows Ameren Missouri to distribute power generated from the High Prairie Renewable Energy Center.
Support Services Agreements
Ameren Services provides support services to its affiliates, including ATXI. The costs of support services including wages, employee benefits, professional services, and other expenses, are based on, or are an allocation of, actual costs incurred. The support services agreement can be terminated with respect to ATXI at any time by the mutual agreement of Ameren Services and ATXI or by either party with 60 days’ notice before the end of a calendar year.
In addition, Ameren subsidiaries jointly use software owned by ATXI.
Electric Transmission Maintenance and Construction Agreements
ATXI entered into separate agreements with Ameren Missouri and Ameren Illinois in which Ameren Missouri or Ameren Illinois, as applicable, may perform certain maintenance and construction services related to ATXI’s electric transmission assets. See Effects of Related-party Transactions on the Statement of Income below for disclosure of maintenance services for 2022 and 2021. ATXI did not receive any construction services under these agreements in 2022 and the cost of construction services received under these agreements was immaterial in 2021.
Money Pool and Notes Payable to Ameren
See Note 5 – Short-term Debt and Liquidity and Note 6 – Long-term Debt and Note Payable to Ameren for a discussion of affiliate borrowing arrangements.
Tax Allocation Agreement
See Note 2 – Summary of Significant Accounting Policies for a discussion of the tax allocation agreement. The following table presents the affiliate balances related to income taxes for ATXI as of December 31, 2022 and 2021:

ELECTRIC PLANT IN SERVICE (Account 101, 102, 103 and 106)
  1. Report below the original cost of electric plant in service according to the prescribed accounts.
  2. In addition to Account 101, Electric Plant in Service (Classified), this page and the next include Account 102, Electric Plant Purchased or Sold; Account 103, Experimental Electric Plant Unclassified; and Account 106, Completed Construction Not Classified-Electric.
  3. Include in column (c) or (d), as appropriate, corrections of additions and retirements for the current or preceding year.
  4. For revisions to the amount of initial asset retirement costs capitalized, included by primary plant account, increases in column (c) additions and reductions in column (e) adjustments.
  5. Enclose in parentheses credit adjustments of plant accounts to indicate the negative effect of such accounts.
  6. Classify Account 106 according to prescribed accounts, on an estimated basis if necessary, and include the entries in column (c). Also to be included in column (c) are entries for reversals of tentative distributions of the prior year reported in column (b). Likewise, if the respondent has a significant amount of plant retirements which have not been classified to primary accounts at the end of the year, include in column (d) a tentative distribution of such retirements, on an estimated basis, with appropriate contra entry to the account for accumulated depreciation provision. Include also in column (d) distributions of these tentative classifications in columns (c) and (d), including the reversals of the prior years tentative account distributions of these amounts. Careful observance of the above instructions and the texts of Accounts 101 and 106 will avoid serious omissions of the reported amount of respondent’s plant actually in service at end of year.
  7. Show in column (f) reclassifications or transfers within utility plant accounts. Include also in column (f) the additions or reductions of primary account classifications arising from distribution of amounts initially recorded in Account 102, include in column (e) the amounts with respect to accumulated provision for depreciation, acquisition adjustments, etc., and show in column (f) only the offset to the debits or credits distributed in column (f) to primary account classifications.
  8. For Account 399, state the nature and use of plant included in this account and if substantial in amount submit a supplementary statement showing subaccount classification of such plant conforming to the requirement of these pages.
  9. For each amount comprising the reported balance and changes in Account 102, state the property purchased or sold, name of vendor or purchase, and date of transaction. If proposed journal entries have been filed with the Commission as required by the Uniform System of Accounts, give also date.

Offset to certain deferred tax liabilities for the probable recovery through future customer rates of tax benefits related to the equity component of allowance for funds used during construction and the effects of tax rate changes from the Tax Cuts and Jobs Act and the increased income tax rate in Illinois. Amounts associated with the equity component of allowance for funds used during construction are amortized over the expected life of the related assets. In 2018, amortization for balances related to the Tax Cuts and Jobs Act began; the amortization period for non-plant balances is 7 years and the expected life of the related assets for plant-related balances.

Q4
SALES FOR RESALE (Account 447)
  1. Report all sales for resale (i.e., sales to purchasers other than ultimate consumers) transacted on a settlement basis other than power exchanges during the year. Do not report exchanges of electricity ( i.e., transactions involving a balancing of debits and credits for energy, capacity, etc.) and any settlements for imbalanced exchanges on this schedule. Power exchanges must be reported on the Purchased Power schedule (Page 326).
  2. Enter the name of the purchaser in column (a). Do note abbreviate or truncate the name or use acronyms. Explain in a footnote any ownership interest or affiliation the respondent has with the purchaser.
  3. In column (b), enter a Statistical Classification Code based on the original contractual terms and conditions of the service as follows:

    RQ - for requirements service. Requirements service is service which the supplier plans to provide on an ongoing basis (i.e., the supplier includes projected load for this service in its system resource planning). In addition, the reliability of requirements service must be the same as, or second only to, the supplier's service to its own ultimate consumers.

    LF - for tong-term service. "Long-term" means five years or Longer and "firm" means that service cannot be interrupted for economic reasons and is intended to remain reliable even under adverse conditions (e.g., the supplier must attempt to buy emergency energy from third parties to maintain deliveries of LF service). This category should not be used for Long-term firm service which meets the definition of RQ service. For all transactions identified as LF, provide in a footnote the termination date of the contract defined as the earliest date that either buyer or setter can unilaterally get out of the contract.

    IF - for intermediate-term firm service. The same as LF service except that "intermediate-term" means longer than one year but Less than five years.

    SF - for short-term firm service. Use this category for all firm services where the duration of each period of commitment for service is one year or less.

    LU - for Long-term service from a designated generating unit. "Long-term" means five years or Longer. The availability and reliability of service, aside from transmission constraints, must match the availability and reliability of designated unit.

    IU - for intermediate-term service from a designated generating unit. The same as LU service except that "intermediate-term" means Longer than one year but Less than five years.

    OS - for other service. use this category only for those services which cannot be placed in the above-defined categories, such as all non-firm service regardless of the Length of the contract and service from designated units of Less than one year. Describe the nature of the service in a footnote.

    AD - for Out-of-period adjustment. Use this code for any accounting adjustments or "true-ups" for service provided in prior reporting years. Provide an explanation in a footnote for each adjustment.

  4. Group requirements RQ sales together and report them starting at line number one. After listing all RQ sales, enter "Subtotal - RQ" in column (a). The remaining sales may then be listed in any order. Enter "Subtotal-Non-RQ" in column (a) after this Listing. Enter "Total'' in column (a) as the Last Line of the schedule. Report subtotals and total for columns (g) through (k).
  5. In Column (c), identify the FERC Rate Schedule or Tariff Number. On separate Lines, List all FERC rate schedules or tariffs under which service, as identified in column (b), is provided.
  6. For requirements RQ sales and any type of-service involving demand charges imposed on a monthly (or Longer) basis, enter the average monthly billing demand in column (d), the average monthly non-coincident peak (NCP) demand in column (e), and the average monthly coincident peak (CP) demand in column (f). For all other types of service, enter NA in columns (d), (e) and (f). Monthly NCP demand is the maximum metered hourly (60-minute integration) demand in a month. Monthly CP demand is the metered demand during the hour (60-minute integration) in which the supplier's system reaches its monthly peak. Demand reported in columns (e) and (f) must be in megawatts. Footnote any demand not stated on a megawatt basis and explain.
  7. Report in column (g) the megawatt hours shown on bills rendered to the purchaser.
  8. Report demand charges in column (h), energy charges in column (i), and the total of any other types of charges, including out-of-period adjustments, in column (j). Explain in a footnote all components of the amount shown in column (j). Report in column (k) the total charge shown on bills rendered to the purchaser.
  9. The data in column (g) through (k) must be subtotaled based on the RQ/Non-RQ grouping (see instruction 4), and then totaled on the Last -line of the schedule. The "Subtotal - RQ" amount in column (g) must be reported as Requirements Sales For Resale on Page 401, line 23. The "Subtotal - Non-RQ" amount in column (g) must be reported as Non-Requirements Sales For Resale on Page 401,line 24.
  10. Footnote entries as required and provide explanations following all required data.

Q4
PURCHASED POWER (Account 555)
  1. Report all power purchases made during the year. Also report exchanges of electricity (i.e., transactions involving a balancing of debits and credits for energy, capacity, etc.) and any settlements for imbalanced exchanges.
  2. Enter the name of the seller or other party in an exchange transaction in column (a). Do not abbreviate or truncate the name or use acronyms. Explain in a footnote any ownership interest or affiliation the respondent has with the seller.
  3. In column (b), enter a Statistical Classification Code based on the original contractual terms and conditions of the service as follows:

    RQ - for requirements service. Requirements service is service which the supplier plans to provide on an ongoing basis (i.e., the supplier includes projects load for this service in its system resource planning). In addition, the reliability of requirement service must be the same as, or second only to, the supplier's service to its own ultimate consumers.

    LF - for long-term firm service. "Long-term" means five years or longer and "firm" means that service cannot be interrupted for economic reasons and is intended to remain reliable even under adverse conditions (e.g., the supplier must attempt to buy emergency energy from third parties to maintain deliveries of LF service). This category should not be used for long-term firm service firm service which meets the definition of RQ service. For all transaction identified as LF, provide in a footnote the termination date of the contract defined as the earliest date that either buyer or seller can unilaterally get out of the contract.

    IF - for intermediate-term firm service. The same as LF service expect that "intermediate-term" means longer than one year but less than five years.

    SF - for short-term service. Use this category for all firm services, where the duration of each period of commitment for service is one year or less.

    LU - for long-term service from a designated generating unit. "Long-term" means five years or longer. The availability and reliability of service, aside from transmission constraints, must match the availability and reliability of the designated unit.

    IU - for intermediate-term service from a designated generating unit. The same as LU service expect that "intermediate-term" means longer than one year but less than five years.

    EX - For exchanges of electricity. Use this category for transactions involving a balancing of debits and credits for energy, capacity, etc. and any settlements for imbalanced exchanges.

    OS - for other service. Use this category only for those services which cannot be placed in the above-defined categories, such as all non-firm service regardless of the Length of the contract and service from designated units of Less than one year. Describe the nature of the service in a footnote for each adjustment.

    AD - for out-of-period adjustment. Use this code for any accounting adjustments or "true-ups" for service provided in prior reporting years. Provide an explanation in a footnote for each adjustment.

  4. In column (c), identify the FERC Rate Schedule Number or Tariff, or, for non-FERC jurisdictional sellers, include an appropriate designation for the contract. On separate lines, list all FERC rate schedules, tariffs or contract designations under which service, as identified in column (b), is provided.
  5. For requirements RQ purchases and any type of service involving demand charges imposed on a monnthly (or longer) basis, enter the monthly average billing demand in column (d), the average monthly non-coincident peak (NCP) demand in column (e), and the average monthly coincident peak (CP) demand in column (f). For all other types of service, enter NA in columns (d), (e) and (f). Monthly NCP demand is the maximum metered hourly (60-minute integration) demand in a month. Monthly CP demand is the metered demand during the hour (60-minute integration) in which the supplier's system reaches its monthly peak. Demand reported in columns (e) and (f) must be in megawatts. Footnote any demand not stated on a megawatt basis and explain.
  6. Report in column (g) the megawatthours shown on bills rendered to the respondent, excluding purchases for energy storage. Report in column (h) the megawatthours shown on bills rendered to the respondent for energy storage purchases. Report in columns (i) and (j) the megawatthours of power exchanges received and delivered, used as the basis for settlement. Do not report net exchange.
  7. Report demand charges in column (k), energy charges in column (l), and the total of any other types of charges, including out-of-period adjustments, in column (m). Explain in a footnote all components of the amount shown in column (m). Report in column (n) the total charge shown on bills received as settlement by the respondent. For power exchanges, report in column (n) the settlement amount for the net receipt of energy. If more energy was delivered than received, enter a negative amount. If the settlement amount (m) include credits or charges other than incremental generation expenses, or (2) excludes certain credits or charges covered by the agreement, provide an explanatory footnote.
  8. The data in columns (g) through (n) must be totaled on the last line of the schedule. The total amount in columns (g) and (h) must be reported as Purchases on Page 401, line 10. The total amount in column (i) must be reported as Exchange Received on Page 401, line 12. The total amount in column (j) must be reported as Exchange Delivered on Page 401, line 13.

FOOTNOTE DATA

(a) Concept: PaymentByCompanyOrPublicAuthority
This footnote applies to line 1, columns (h), (i), and (j):
As all revenue is collected by MISO and distributed to ATXI under the MISO Transmission Owner’s Agreement, billing demand and energy transfer information is unavailable.
(b) Concept: PaymentByCompanyOrPublicAuthority
This footnote applies to line 1, column (d)

Since this line includes all revenue collected by MISO and distributed to ATXI under the MISO Transmission Owner's Agreement, billing demand information is unavailable. This includes all types of transmission service classifications.
(c) Concept: PaymentByCompanyOrPublicAuthority
ATXI is a transmission owning member within the AMIL and AMMO Pricing Zones of the MISO Regional Transmission Organization (RTO). ATXI is not a transmission provider. ATXI serves no load. ATXI did not sell transmission services or ancillary services directly. Instead, ATXI received revenues from transmission and ancillary services sold by MISO. MISO distributes the revenues that it receives to the transmission owners. ATXI is also allocated a portion of the revenue collected for each Pricing Zone based on its respective revenue requirement within each Pricing Zone.
(d) Concept: PaymentByCompanyOrPublicAuthority
This footnote applies to line 2, columns (a) through (d):
Adjusted revenues to reflect revised revenue requirement based on preliminary actual results for the current year. The true-up also included an adjustment for load and the true-up for the prior calendar year's actuals. This includes all types of transmission service classifications. For Schedule 1, the true-up also included an adjustment for prior years.
(e) Concept: DemandChargesRevenueTransmissionOfElectricityForOthers

FOOTNOTE DATA

(a) Concept: AncillaryServicesSoldAmount
ATXI is a transmission owning member within the AMIL and AMMO Pricing Zones of the MISO Regional Transmission Organization (RTO). ATXI is not a transmission provider. ATXI serves no load. ATXI did not sell transmission services or ancillary services directly. Instead, ATXI received revenues from transmission and ancillary services sold by MISO. MISO distributes the revenues that it receives to the transmission owners. ATXI is also allocated a portion of the revenue collected for each Pricing Zone based on its respective revenue requirement within each Pricing Zone.
