(Dollars in thousands)

  1. Organization and Significant Developments

On December 19, 2001, Midcontinent Independent System Operator, Inc. (MISO or the Company) became the nation's first Regional Transmission Organization approved by the Federal Energy Regulatory Commission (the FERC or the Commission). As a Regional Transmission Organization, MISO provides transmission service on behalf of its members that own transmission assets. In addition, MISO is a North American Electric Reliability Corporation (NERC) certified reliability coordinator. In that capacity, MISO monitors the flow of electricity over the transmission systems of its members that own transmission assets.

MISO was incorporated as a Delaware non-stock, nonprofit corporation in March 1998. The Company is governed by an independent Board of Directors. Membership in MISO is open to owners of electric transmission facilities, as well as other participants in the electric energy market. Fifty-six transmission owners with more than 68,000 miles of transmission lines and 190,000 megawatts of electric generation are currently participating in MISO.

On December 15, 2001, the Company began providing reliability coordination services to the transmission-owning members of MISO and their customers. On the same date, MISO also began providing operations planning, generation interconnection, maintenance coordination, long-term regional planning, market monitoring, and dispute resolution services. The Company commenced substantially all operations on February 1, 2002, the date MISO began providing regional transmission service under its FERC-accepted Open Access Transmission and Energy Markets Tariff (the Tariff).

On April 1, 2005, MISO formally began operating a market-based, congestion management system, which features the day-ahead energy market, real-time energy market, and financial transmission rights market. The day-ahead and real-time energy markets are designed to reliably make the most efficient use of all generation and transmission resources within the region based on bids and offers submitted by market participants. The day-ahead and real-time energy markets price transmission system congestion through the use of Locational Marginal Pricing algorithms. The financial transmission rights market provides a means of hedging Locational Marginal Pricing-based congestion costs.

On January 6, 2009, MISO began operating a market for ancillary services, which integrates the procurement and use of regulation and contingency reserves with the existing real-time energy market. MISO also became a NERC-certified Balancing Authority on January 6, 2009.

  1. Summary of Significant Accounting Policies

Basis of PresentationThe accompanying financial statements have been prepared in accordance with the accounting requirements of FERC as set forth in the applicable Uniform System of Accounts and published accounting releases, which is a comprehensive basis of accounting other than general accepted accounting principles in the United States of America. The principal difference from U.S. GAAP relates to the presentation of current maturities of long-term debt and the recognition of debt issuance costs. U.S. GAAP requires that current maturities of long-term debt be reported as a current liability on the Balance Sheet and debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. For FERC reporting, current maturities of long-term debt are included with long-term debt on the Balance Sheet and the unamortized expense of issuance shall be recorded in account 181, Unamortized Debt Expense. Another difference from U.S. GAAP is the accounting treatment of internal-use software as an intangible asset. FERC account 101 on the Balance Sheet shall include the original cost of electric plant, included in accounts 301 to 399, owned and used by the utility in its electric utility operations, and having an expectation of life in service of more than one year from date of installation. For GAAP purposes, available-for-sale investments are classified as current assets as they are available to be converted into cash to fund current operations, even though some investments have contractual maturities beyond one year from the Balance Sheet date. For FERC reporting, investments and any unrealized gains and losses are recorded in account 124, Other investments as a component of non-current assets on the Balance Sheets. The Company choose to implement guidance provided by ASU 2016-02 to report operating leases with a lease term in excess of 12 months as right of use assets, with corresponding lease obligations, in the balance sheet accounts established for capital leases (Accounts 101.1, 227, and 243).

RegulationMISO is subject to regulation by the FERC and accounts for the effects of regulation in its financial statements in accordance with Accounting Standards Codification (ASC) 980,Regulated Operations. This statement sets forth the application of generally accepted accounting principles for those companies whose rates are established by, or are subject to approval by, an independent third-party regulator. Under ASC 980, regulated companies defer costs and credits on the balance sheets as regulatory assets and liabilities when it is probable that those costs and credits will be recognized in the rate-setting process in a period different from the period in which they would have been reflected in income and expense by an unregulated company. These deferred regulatory assets and liabilities are then reflected in the statements of operations and changes in net assets in the period in which the same amounts are reflected in rates charged for service.

Use of EstimatesThe preparation of financial statements in conformity with FERC requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Cash, Cash Equivalents and Restricted CashThe Company considers all highly liquid investments with a maturity of ninety days or less from the date of purchase to be cash equivalents. Cash and cash equivalents consist of checking accounts, money market accounts, money market mutual funds, and certificates of deposit with a maturity date of ninety days or less. The carrying values of cash and cash equivalents approximate the fair market value. Certificates of deposit, commercial paper, corporate notes and corporate bonds with a maturity date of more than ninety days from the date of purchase are classified separately as investments on the balance sheet. Restricted Cash is further discussed in Note 5.

Concentration of Credit RiskFinancial instruments that subject the Company to credit risk consist primarily of accounts receivable and uninsured cash balances. The Company maintained cash balances in excess of insured Federal Deposit Insurance Corporation limits at December 31, 2022 and 2021, and from time to time through December 31, 2022. No allowance has been recorded for accounts receivable at December 31, 2022 and 2021, as management considers all accounts receivable reported in these financial statements to be probable of collection. Furthermore, MISO, per the Tariff, limits distribution of funds owed to market participants to the amount received from market participants. As such, MISO is not exposed to nonpayment for Tariff services.

InvestmentsInvestment securities may consist of investments in U.S. Treasuries, various U.S. governmental agency debt securities, corporate bonds, certificates of deposit, and other fixed income securities that have initial maturities of greater than ninety days from date of purchase. Management classifies the Company's investments as available-for-sale. Such securities are carried at fair value based upon prices for identical or similar items on the last day of the fiscal period, with any unrealized gains or losses reported as a deferred regulatory asset or liability, and realized gains and losses included in the statement of operations and changes in net assets. Dividend and interest income is recognized as interest income when earned. Management uses the specific identification method to determine the cost of securities sold. There were no investments recorded as of December 2022 and December 31, 2021.

Intangible AssetsIntangible assets primarily include capitalized software of $470,353 and $445,206 and its corresponding accumulated amortization of $368,328 and $351,537, as of December 31, 2022 and 2021, respectively. Amortization expense was $17,494 and $17,991 for the years ended December 31, 2022 and 2021, respectively. The Company retired $702 and $445 of intangible assets in 2022 and 2021 that were fully amortized. The average remaining amortization period for these assets is 2.5 years. Costs incurred prior to the determination of feasibility of developed software and following the in-service date of developed software are expensed.

Fixed AssetsFixed assets, consisting primarily of telecommunications equipment, computer equipment, buildings, leasehold improvements, and furniture and fixtures, are recorded at cost and are depreciated on a straight-line basis over the estimated useful lives of the assets. The major classes and lives include the following: buildings and improvements, 20 years; computer hardware, 3 years or 6 years; furniture and fixtures, 7 years; and telecommunications equipment, 7 years. Cost consists of materials and supplies, labor, related taxes, and capitalized interest.

There was $2,643 and $2,353 of interest capitalized in fixed assets for the years ended December 31, 2022 and 2021, respectively. The depreciation policy for leaseholds is the shorter of the life of the asset or the remaining term of the lease. Maintenance and repair costs are charged to expense when incurred. Effective January 31, 2015, the Company received approval from the FERC to amortize the cost of land on straight-line basis over a five-year period.

PensionMISO accounts for its defined benefit pension plan (the MISO floor offset plan) in accordance with ASC 715,Retirement Benefits. This standard requires employers to fully recognize the obligations associated with single-employer, defined benefit pension, retiree health care, and other postretirement plans in their financial statements. Rate-regulated entities may recognize regulatory assets or liabilities as a result of timing differences between the recognition of costs and costs recovered through the rate-making process.

PrepaymentsThe Company considers any expenditure greater than five thousand dollars that will provide future benefits for at least three months as a prepaid asset. Prepaid assets are amortized to expense over the useful life of the asset.

Fair Value MeasurementsThe Company uses a three-tier fair value hierarchy in accordance with ASC 820,Fair Value Measurement, which prioritizes the inputs used in measuring fair value. Hierarchical levels, as defined in Financial Accounting Standards Board (FASB) guidance and explained in the following paragraphs, are directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities:

Level 1Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity can access at the measurement date. The Company's investments associated with its pension plan and Supplemental Executive Retirement Plan, along with its investments in U.S. treasuries are categorized as Level 1.

Level 2Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. The Company holds investments that consist of certificates of deposit, corporate bonds and other fixed income securities and are categorized as Level 2.

Level 3Unobservable inputs for the asset or liability, which include management's own assumption about the assumptions market participants would use in pricing the asset or liability, including assumptions about risk. The Company did not hold any investments in Level 3 securities as of December 31, 2022 and 2021, respectively.

Fair values of investments are estimated using public market prices, quotes from investments and other available information. The estimated fair value of notes payable is discussed in Note 13.

Revenue RecognitionThe Company adopted the requirements of Accounting Standards Update (ASU )2014-09,Revenue from Contracts with Customers (Topic 606), under the modified retrospective approach effective January 1, 2019. The Company adopted this standard for interim periods beginning January 1, 2020. The adoption did not have a material impact on the amount or timing of revenue recognized. The Company's operating revenues are derived primarily from recovery of administrative costs under the Tariff, with no defined contractual term. Under ASC 606, revenue is to be recognized when performance obligations are satisfied. Pursuant to the Tariff, MISO recognizes as revenue amounts both billed and unbilled for which MISO has incurred costs as of the period-end.

The Schedule 10ISO Cost Recovery Adder, Schedule 16Financial Transmission Rights Administrative Service Cost Recovery Adder, and Schedule 17Energy Market Support Administrative Service Cost Recovery Adder of the Tariff provide for recovery of all costs, including capital and operating expenses, of MISO. MISO also recognizes as revenue amounts billed to participants for initial membership, training, and annual dues. Performance obligations are satisfied over time as Transmission and Administrative Services are delivered, with billings generally occurring monthly and related payments due within seven days.

MISO records revenue and an offsetting expense for the annual FERC Assessment Fee (the Assessment Fee). The annual fee is assessed on the megawatt hours of transmission usage for each transmission provider as reported on FERC Form 582.

The FERC generally invoices transmission providers in July of each year, and payment is due in August. MISO bills the Assessment Fee monthly in advance based on an estimated rate per megawatt hour applied to each individual transmission customer's actual megawatt hours of transmission usage for that month. MISO recognizes the revenue and an offsetting expense each month as the Assessment Fee is billed. Assessment Fee revenue of $68,171 and $64,073 was recorded in 2022 and 2021, respectively.

MISO performs engineering studies on behalf of its customers. MISO is reimbursed for its costs of performing the studies and recognizes revenue as the costs are incurred, subject to a recoverability assessment. The amounts of $20,810 and $18,438 were recognized as revenue from engineering studies for the years ended December 31, 2022 and 2021, respectively.

MISO has been awarded a number of economic development grants by the state of Indiana, as well as a United States Department of Energy (DOE) grant. Revenue is recognized on these grants based on the terms of the agreement, which generally are based on a percentage of program costs incurred. MISO recognized revenue associated with these programs of $102 and $394 in 2022 and 2021, respectively.

The Company recorded deferred revenue associated with withdrawal obligations paid by transmission owners that have withdrawn from MISO. Each transmission owner can receive credits for service up to the amount of the original exit fee until the year expiring, noted in the table below. Amounts are amortized ratably over the period from the year of withdrawal through expiration. The table also notes the exit fees and remaining balances in the current and prior years.

Of the $12,362, $3,460 is recorded as current deferred revenue and is expected to be amortized to revenue in 2023.

Subsequent EventsManagement has evaluated events and transactions occurring since December 31, 2022. There are no events or transactions that have occurred that require additional disclosure in these financial statements after December 31, 2022 through March 22, 2023, the date the financial statements were available to be issued.

New Accounting GuidanceInFebruary 2016, the FASB issued ASU 2016-02,Leases (Topic 842), whichrequires lessees to recognize most leases on the balance sheet and disclose keyinformation to help investors and other financial statement users betterunderstand the amount, timing, and uncertainty of cash flows arising fromleases.The new standard required thatlessees recognize the following for all leases (with the exception ofshort-term leases, as that term is defined in the standard) at the leasecommencement date: (1) a lease liability, which is a lessee's obligation tomake lease payments arising from a lease, measured on a discounted basis; and(2) a right-of-use asset, which is an asset that represents the lessee's rightto use, or control the use of, a specified asset for the lease term.Leases will be classified as finance oroperating, with classification affecting the pattern and classification ofexpense recognition in the income statement.

On July 30, 2018, the FASB issued ASU 2018-11 to provide entities provides an adoption method that allows companies to apply the new guidance to the financial statements in the period of adoption and thereafter, and not apply the new guidance to comparative periods presented. ASU 2018-11 allows an entity to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application.

MISO adopted the provision of ASC 842 beginning on January 1, 2022, using the transition method provided in ASU 2018-11, which was applied to all existing leases at that date. As such, results for reporting periods beginning after January 1, 2022 will be presented under ASC 842, while prior period amounts will continue to be reported in accordance with ASC 840.

Management elected the following practical expedients: Package of transition practical expedients; Short term lease expedient; Hindsight expedient.

Adoption of the new standard resulted in the recording of additional lease liabilities of $30,421and a corresponding Right of Use Asset of $29,383 on our Balance Sheets as of January 1, 2022. We utilize our collateralized incremental borrowing rate commensurate to the lease term as the discount rate for all our leases.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (Topic 326), which amends the Board's guidance on the impairment of financial instruments.

Subsequently, the FASB has issued additional ASU which further clarify this guidance. The ASU adds to GAAP an impairment model that is based on expected losses rather than incurred losses, which is known as the current expected credit loss (CECL) model. The CECL model applies to most debt instruments (other than those measured at fair value), trade and other receivables, financial guarantee contracts, and loan commitments. ASU 2016-13 is effective for our fiscal years beginning after December 31, 2022. The Company is evaluating the effect of adopting this new accounting guidance but does not expect adoption will have a material impact on the Company's financial position or results of operations.

  1. Members' Preservation of Withdrawal Notice

Some members provide a notice of withdrawal to MISO in accordance with the terms of the MISO Transmission Owners Agreement. Such notices allow these companies to preserve their options with respect to withdrawal of their facilities from MISO. Should these companies withdraw, they would then be responsible to pay their proportionate share of certain outstanding financial obligations of MISO and for certain other obligations as required by the terms of the MISO Transmission Owners Agreement and the Tariff. Below is a listing of members that provided a notice of withdrawal:

  1. DEFERRED Regulatory Assets and Liabilities

The following regulatory assets and liabilities were included in the deferred regulatory assets and liabilities lines on the balance sheets:

The Current Schedule 10, 16 and 17 rates are based on forecasted billing units and expenditures. Differences between revenue collected and actual costs for the month are included in subsequent months' rate calculations. These costs are classified as deferred regulatory assets and will be recovered in a subsequent period.

  1. Cash, Cash Equivalents and Restricted Cash

The Company considers all highly liquid investment instruments that mature within ninety days or less to be cash equivalents. Cash, cash equivalents and restricted cash had the following balances, which approximate fair value, as of December 31:

All restricted cash items are offset by liabilities on the balance sheets. The cash and cash equivalent collateral deposits less interest are offset in restricted deposits. Collection on the Assessment Fee is offset by the FERC assessment liability. The remainder of restricted cash and cash equivalents is offset in the market participant liability.

Restricted cash for market funds consists of activity for two funds: the Day-Ahead Excess Congestion Fund and the Financial Transmission Rights Auction Residual Fund. The Day-Ahead Excess Congestion Fund consists of excess cash received after the funding of Financial Transmission Rights. The Financial Transmission Rights Auction Residual Fund represents excess payments received for Financial Transmission Rights sold in the monthly and annual auctions. Both funds are accumulated during the calendar month and distributed to market participants per formulas in the Tariff after the end of each calendar month.

As of December 31, 2022 and 2021, the Company had collected $35,592 and $5,498, respectively, in market participant payments due to other market participants and/or MISO transmission owners. These funds are scheduled to be paid in a subsequent period.

The cash collateral deposits represent funds from customers that provide cash collateral as a form of financial assurance to secure the customers' performance under the terms and conditions of the Tariff related to the purchase of transmission service, market services, ancillary services, and related products or services. Also included in this amount is interest earned on the deposits, which is paid to the customer quarterly on January 31, April 30, July 31 and October 31 of each year. As of December 31, 2022 and 2021, the Company had collected $1,499,136 and $1,088,287, respectively, of security deposits from customers. An offsetting liability is recorded in current and long-term liabilities. At December 31, 2022 and 2021, interest payable to the customers of $14,272 and $29, respectively, was recorded in accrued interest.

MISO bills to its market participants the Assessment Fee monthly and accumulates the cash in a segregated account for use in paying the annual Assessment Fee in August of each year. As of December 31, 2022 and 2021, the amount restricted for this use was $25,979 and $21,507, respectively.

  1. Accounts Receivable

Unbilled revenues are recognized by applying tariffed rates to the usage incurred but not yet billed. The accrual for unbilled revenues is reversed in the subsequent accounting period when customers are billed. MISO's receivables at December 31, 2022 and 2021, consist of the following:

  1. Fixed Assets

Fixed assets at December 31, 2022 and 2021, consist of the following:

Total depreciation and amortization expense related to fixed assets was $14,325 and $14,460 for 2022 and 2021, respectively. At December 31, 2022 and 2021, the balance of projects in development was $5,708 and $10,033, respectively. These amounts included funds expended to develop projects to improve internal business processes, improve IT infrastructure, and enhance operations systems.

  1. Accrued Liabilities

Current and long-term accrued liabilities at December 31, 2022 and 2021, consist of the following:

Market participants that request a generation interconnection or facility upgrade study must pay the costs incurred to perform an impact assessment study. Furthermore, a deposit is required before the study is undertaken. At December 31, 2022 and 2021, the engineering study deposits balance was comprised of $1,276,676 and $873,204, respectively, for generation interconnection studies and facility upgrade studies. These balances are held within various accounts as cash and cash equivalents and short-term investments. As expenses are incurred, revenue is recognized and deducted from the deposits, and liabilities, for services performed by MISO for these impact assessment studies.

  1. Retirement Plans

The Company offers a defined contribution 401(k) retirement plan for all full-time employees as of their date of hire. The Company currently matches 50% of the first 6% of the employee contribution. For December 31, 2022 and 2021, the Company match was $3,387 and $3,668, respectively. Employees are 100% vested in the employer's contribution after two years of employment.

The Company also has a defined contribution retirement plan covering all full-time employees. The Company contributes an amount equal to 6% of an employee's salary into the plan for the employee's retirement. For December 31, 2022 and 2021, the cost of this plan was $7,046 and $6,587, respectively. Contributions are subject to a vesting schedule. Employees are 100% vested after five years of employment.

The Company has a Supplemental Executive Retirement Plan for officers and a plan under Section 457(b) of the Internal Revenue Code. Benefits payable under these plans are based upon the participant's salary and age. The investment balance at December 31, 2022 and 2021, is $12,183 and $12,931, respectively, and is recorded in other assets. An offsetting liability is also recorded in accrued liabilities. Expense relating to the Supplemental Executive Retirement Plan of $1,381 and $1,340 was recorded for the years ended December 31, 2022 and 2021, respectively.

MISO assumed a defined benefit pension plan (the MISO Floor Offset Plan) established for Mid-Continent Area Power Pool (MAPPCOR) employees who became employees of MISO under the terms and conditions of an asset purchase agreement completed in November 2001. Effective April 15, 2006, the MISO Floor Offset Plan was frozen. The Company made the decision to terminate the plan effective December 31, 2021. On July 15, 2021, the Company transferred $2,307 from the MISO Floor Offset Plan to Mutual of Omaha, who will administer the payment of benefits to the 15 individuals currently receiving benefits starting September 1, 2021. The Company contributed $455 to bring the plan to fully funded status. The remaining plan participants received lump sum distributions on December 31, 2021, which brought the fair value of plan assets to $0.

  1. Income Taxes

The Company has received approval for its not-for-profit status under Section 501(a) of the Internal Revenue Code and is tax-exempt as an organization described in Internal Revenue Code Section 501(c)(4).

  1. Leases

The Company is the lessee for substantially all its leasing activity, which includes operating leases for business offices, hardware, and IT assets. The average remaining lease terms for the Company's business office leases is 5 years. The Company's leased IT assets and hardware have a remaining average lease term of 2 years. The weighted average remaining lease term as of December 31, 2022 is 3 years.

The weighted-average discount rate as of January 1, 2022, was 2.0%. The rate implicit in the lease is not readily determinable in the lease agreements; therefore, the Company estimated the incremental borrowing rate, at the commencement date of each lease, which is the rate of interest it would have to borrow on a collateralized basis over a similar term with similar payments.

Total expenses incurred under all operating leases were $6,816 and $4,979 for the years ended December 31, 2022 and 2021, respectively. The components of lease expense for the year ended December 31, 2022, were as follows:

As of December 31, 2022, the Company had a Right of Use Asset of $24,560 and a corresponding lease liability of $25,510. Maturities of operating lease liabilities as of December 31, 2022:

  1. Bank Line of Credit

The Company has a credit agreement with PNC Bank and JPMorgan Chase Bank, N.A. The credit agreement is set to expire on February 15th, 2023. On February 16, 2023, the FERC approved the Company's issuance of long-term debt which allows the Company to continue to incur indebtedness under its credit agreement for an additional two-year period. The maximum amount available under the line was $50,000 at December 31, 2022. There was no outstanding balance at December 31, 2022 or 2021. Borrowings are payable on demand. Advances bear interest at either the floating rate or Eurodollar rate. The line of credit contains certain restrictive financial and other covenants, including limitations on indebtedness, participation in mergers, sale of assets, investments, acquisitions, liens, and prepayment of indebtedness. The Company incurred closing fees of $189 to renew the credit agreement and recognized the expense in 2021.

  1. Long-Term Notes

Long-term debt consisted of the following:

Maturities of long-term debt are as follows:

On March 26, 2013, the Company issued notes with a face value of $100,000 to a group of institutional lenders. The notes are unsecured senior obligations of the Company that mature on March 26, 2033, with mandatory principal payments of $20,000 payable beginning on March 26, 2029, and on each March 26 thereafter, up to and including March 26, 2033, and bear interest at 3.96% per annum, payable semiannually on March 26 and September 26 of each year, commencing September 26, 2013. The notes have no mandatory sinking fund requirement but are redeemable, in whole or in part, at the option of the Company. The notes contain certain restrictive covenants, including limitations on payments, liens, leases, distributions, purchases, and certain investments. The Company incurred note offering fees aggregating $412 and amortized as a component of interest expense over the term of the notes.

On October 5, 2017, the Company issued notes with a face value of $175,000 to a group of institutional lenders. The notes are unsecured senior obligations of the Company that mature on October 5, 2047, with mandatory principal payments of $17,500 payable beginning on October 5, 2038, and on each October 5 thereafter, up to and including October 5, 2047, and bear interest at 3.91% per annum, payable semiannually on April 5 and October 5 of each year, commencing April 5, 2018. The notes have no mandatory sinking fund requirement but are redeemable, in whole or in part, at the option of the Company. The notes contain certain restrictive covenants, including limitations on payments, liens, leases, distributions, purchases, and certain investments. The Company incurred note offering fees aggregating $525 and amortized as a component of interest expense over the term of the notes.

Management has estimated the fair value of each of the notes payable based on the trading prices of similarly rated securities at December 31, 2022 and 2021. The fair values for each note payable are presented in the following table:

  1. Commitments and Contingencies

On August 5, 2022, MISO received notification that an employee filed a charge of age and disability discrimination against MISO with the Equal Employment Opportunity Commission (EEOC). The EEOC issued a Notice of Right to Sue on December 24, 2022 without making a determination. On January 25, 2023, MISO was served with a complaint filed against the Company by the same employee in federal court, containing the same allegations as those in the EEOC charge. Management estimates that MISO's total costs, including a judgement in favor of the employee and attorneys' fees for both parties, would fall in the range of $2,800 - $3,000.

MISO has Employment Practices Liability Insurance coverage that is expected to apply to any amount paid related to a court ordered obligation or a separate settlement. MISO is estimating its liability at no greater than $1,000 based on the deductible and terms of the policy. The insurance policy is an indemnity-based policy, which means MISO would pay the funds directly and then obtain recovery through a claim under the policy related to any obligation incurred by MISO in connection with the lawsuit.

There are various other claims against the Company incident to its operations. It is the opinion of management that, while unable to predict the outcome of these matters, the ultimate resolution of these matters will not have a material adverse effect on the Company's financial position or results of operations.

The Company self-reports noncompliance with the North American Electric Reliability Corporation Standards throughout the year. In management's opinion, these self-reports will not result in a material impact to the financial statements.

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.

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.

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.

  1. Report information concerning transmission lines, cost of lines, and expenses for year. List each transmission line having nominal voltage of 132 kilovolts or greater. Report transmission lines below these voltages in group totals only for each voltage. If required by a State commission to report individual lines for all voltages, do so but do not group totals for each voltage under 132 kilovolts.
  2. Transmission lines include all lines covered by the definition of transmission system plant as given in the Uniform System of Accounts. Do not report substation costs and expenses on this page.
  3. Exclude from this page any transmission lines for which plant costs are included in Account 121, Nonutility Property.
  4. Indicate whether the type of supporting structure reported in column (e) is: (1) single pole wood or steel; (2) H-frame wood, or steel poles; (3) tower; or (4) underground construction If a transmission line has more than one type of supporting structure, indicate the mileage of each type of construction by the use of brackets and extra lines. Minor portions of a transmission line of a different type of construction need not be distinguished from the remainder of the line.
  5. Report in columns (f) and (g) the total pole miles of each transmission line. Show in column (f) the pole miles of line on structures the cost of which is reported for the line designated; conversely, show in column (g) the pole miles of line on structures the cost of which is reported for another line. Report pole miles of line on leased or partly owned structures in column (g). In a footnote, explain the basis of such occupancy and state whether expenses with respect to such structures are included in the expenses reported for the line designated.
  6. Do not report the same transmission line structure twice. Report Lower voltage Lines and higher voltage lines as one line.

TRANSMISSION LINES ADDED DURING YEAR
  1. Report below the information called for concerning Transmission lines added or altered during the year. It is not necessary to report minor revisions of lines.
  2. Provide separate subheadings for overhead and under- ground construction and show each transmission line separately. If actual costs of competed construction are not readily available for reporting columns (l) to (o), it is permissible to report in these columns the costs. Designate, however, if estimated amounts are reported. Include costs of Clearing Land and Rights-of-Way, and Roads and Trails, in column (l) with appropriate footnote, and costs of Underground Conduit in column (m).
  3. If design voltage differs from operating voltage, indicate such fact by footnote; also where line is other than 60 cycle, 3 phase, indicate such other characteristic.
