Nature of Operations** Mack Investment Securities, Inc. ("MIS"), an Illinois corporation, was incorporated on January 16, 1986. MIS is a broker-dealer registered with the Securities and Exchange Commission and is also a registered investment advisor. MIS provides brokerage services to retail customers. As an investment advisor, MIS provides investment management services to individuals, trusts, retirement plans and corporations. Mack Investment Insurance Brokerage, Inc. ("MII") is a registered insurance agency that sells variable life, variable annuities, fixed life, long-term care as well as fixed and fixed-indexed annuities. The Company's securities business segment derives revenues from customers for commissions and fees for the sale of securities, mutual funds (12b-1's), and insurance products. MIS and MII are licensed to do business in many states in the United States of America. The accompanying combined financial statements reflect the accounts of MIS and MII (collectively, the "Company"), which are under common ownership and management. All significant intercompany transactions have been eliminated in combination. ### **B. Cash and Cash Equivalents** The Company considers cash equivalents to be all highly liquid investments with a maturity of three months or less when purchased. ### **C. Cash Balances in Excess of Insured Amounts** The Company maintains its cash in accounts which, at times, may exceed federally insured limits. The Company has not experienced any losses due to these limits. ## **D. Commissions and Advisory Fees Receivable and Payable** Commissions and advisory fees receivable represent commissions due to the Company from the sale of financial products and are recorded at net realizable value consisting of the carrying amount less an allowance for uncollectible accounts, as needed. Commissions payable represent amounts due to the Company's sales representatives in connection with the sale of financial products. The Company uses the allowance method to account for uncollectible receivable balances. Under the allowance method, if needed, an estimate of uncollectible balances is made based upon expected actual write-offs. Factors used to establish an allowance include the credit quality of the customer and whether the balance is significant. Accounts are considered past due once the unpaid balance is 90 days or more outstanding, unless payment terms are extended by contract. Management did not deem an allowance amount necessary as of December 31, 2025. {6}------------------------------------------------ ## **Note (1) Nature of Operations and Summary of Significant Accounting Policies – Continued** ## **E. Revenue recognition** Revenue is recognized in accordance with FASB ASC Topic 606 as services are rendered and the contracts identified performance obligation has been satisfied. The Company provides investment advisory services on a daily basis. The Company believes the performance obligation for providing advisory services is satisfied over time because the customer is receiving and consuming the benefits as they are provided by the Company. Fee arrangements are based on a percentage applied to the customer's assets under management. Fees are received monthly or quarterly and are recognized as revenue at the time as they relate specifically to the services provided in that period. Commissions received from the sale of mutual funds, variable annuities, and insurance products are recognized at the time the associated service is fulfilled, including the investment company receiving the application which is based on trade date. Brokerage commissions for executing transactions on an exchange or over-the-counter markets are recognized as revenue at the point in time the associated service is fulfilled which is based on the trade date. There were no unsatisfied performance obligations at December 31, 2025. ## *Distribution Fees* The Company enters into arrangements with managed accounts or other pooled investment vehicles (funds) to distribute shares to investors. The Company may receive distribution fees paid by the fund up front, over time, upon the investors' exit from the fund (that is, a contingent deferred sales charge), or as a combination thereof. The Company believes that its performance obligation is the sale of securities to investors and as such this is fulfilled on the trade date. Any fixed amounts are recognized on the trade date and variable amounts are recognized to the extent it is probable that a significant revenue reversal will not occur once the uncertainty is resolved. For variable amounts, as the uncertainty is dependent on the value of the shares at future points in time as well as the length of time the investor remains in the fund, both of which are highly susceptible to factors outside the Company's influence, the Company does not believe that it can overcome this constraint until the market value of the fund and the investor activities are known, which are usually monthly or quarterly. Distribution fees recognized in the current period are primarily related to performance obligations that have been satisfied in prior periods. ### *Interest Income* The Company receives shared "with the clearing firm" interest on customer balances at the clearing firm. {7}------------------------------------------------ ## **Note (1) Nature of Operations and Summary of Significant Accounting Policies – Continued** ## **F. Income Taxes** The stockholder of the Company has elected to be taxed as a small business corporation under Internal Revenue Service Regulations; therefore, no provision for federal or state corporate income taxes is necessary. The income or loss is separately reported on the individual income tax returns of the stockholder for federal and state income tax purposes. The Company is responsible for state replacement taxes, if applicable. The Company accounts for any potential interest or penalties related to the possible future liabilities for unrecognized income tax benefits with other expenses. The Company is no longer subject to examination by tax authorities for federal, state or local income taxes for periods before 2022. ## **G. Use of Estimates** The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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. While actual results may differ from those estimates, management does not expect the differences, if any, to have a material effect on the combined financial statements. ### **Note (2) Receivable from Investment Companies and Broker-Dealers** The Company receives income from fees assessed from investment advisory accounts of the Company. Commissions are received from investment companies on direct application way transactions, from insurance companies for products sold to MIS clients, and from customer-based transactions which are cleared through another broker-dealer on a fully disclosed basis. At December 31, 2025, the Company had investment advisory fees due in the amount of \$325,24, clearing commissions due in the amount of \$9,539, investment company commissions due in the amount of \$50,203, and mutual fund 12b-1's due in the amount of \$54,674 from various investment companies and brokerdealers. {8}------------------------------------------------ ### **Note (3) Credit Losses** The Company follows ASC Topic 326, Financial Instruments – Credit Losses ("ASC 326"). ASC 326 impacts the impairment model for certain financial assets by requiring a current expected credit loss ("CECL") methodology to estimate expected credit losses over the entire life of the financial asset. Under the accounting update, the Company has the ability to determine that there are no expected credit losses in certain circumstances (e.g., based on the credit quality of the customer). ### **Note (4) Segment Reporting** The Company's securities business segment derives revenues from customers for commissions and fees for the sale of securities, mutual funds (12b-1's), and variable annuities. The accounting policies for this segment are the same as those described in Note 1, Summary of Significant Account Policies. The chief operating decision maker assesses performance for the securities business segment and decides allocation of resources based on net income as reported on the income statement and segment assets as reported as total assets on the balance sheet. The chief operating decision maker uses net income to evaluate income generated from segment assets (return on assets) in deciding whether to reinvest profits into this segment or other areas, such as acquisitions or paying dividends. Net income is used to monitor, among other things, budget versus actual result, competitive analysis, and benchmarking. The Company has one reportable segment commission and fees for the sale of securities, mutual funds (12b-1's), and variable annuities, as the primary source of its revenue. The Company's chief operating decision is the President. ### **Note (5) Net Capital Requirement** The Company is subject to the SEC Uniform Net Capital Rule (SEC Rule 15c3-1), which requires the maintenance of minimum net capital and requires that the ratio of aggregate indebtedness to net capital, both as defined, shall not exceed 15 to 1 (and the rule of the "applicable" exchange also provides that equity capital may not be withdrawn or cash dividends paid if the resulting net capital ratio would exceed 10 to 1). At December 31, 2025, the Company had net capital of \$344,332, which was \$294,332 in excess of its required net capital of \$50,000. The Company's net capital ratio was .77 to 1. ## **Note (6) Property and Equipment** Furniture, fixtures, and equipment, net, consists of the following at December 31, 2025 | Furniture and Fixtures | \$17,000 | |-------------------------------|----------| | Less Accumulated Depreciation | 0 | | Total | \$17,000 | {9}------------------------------------------------ ### **Note (7) Vehicles** Vehicles consist of the following at December 31, 2025 | Vehicles | \$77,544 | |-------------------|----------| | Less Depreciation | (20,833) | | Total | \$56,661 | ### **Note (8) Leases** The Company has obligations as a lessee for office space with initial noncancelable terms in excess of one year. The Company classified this lease as an operating lease. This lease does not contain a renewal option. The Company's lease does not include a termination option for either party to the lease. Payments due under the lease contract include a fixed monthly payment of \$5,130 and the total rent expense for 2025 was \$61,558 which is included under Occupancy expense. The minimum lease obligation totals \$235,971. Maturities of the lease obligation under operating leases as of December 31, 2025 are as follows: Year Ending December 31 | 2026 | \$
61,558 | |----------------------|--------------| | 2027 | 61,558 | | 2028 | 61,558 | | 2029 | 51,297 | | Total lease payments | \$235,971 | The Company has elected to recognize the lease payments as lease costs on a straightline basis over the lease term. The Nominal Annual Rate used was five percent (5%). Amounts reported in the balance sheet as of December 31, 2025 were as follows: | Operating lease ROU assets | \$214,330 | |----------------------------|-----------| | Operating lease liability | 214,330 | ### **Note (9) Fair Value Measurements** FASB ASC 820, *Fair value Measurements and Disclosures*, defines fair value, establishes a framework for measuring fair value, and establishes a fair value hierarchy which prioritizes the inputs to valuation techniques. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between {10}------------------------------------------------ market participants at the measurement date. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for **Note (9) Fair Value Measurements – Continued** > the asset or liability or, in the absence of a principal market, the most advantageous market. Valuation techniques that are consistent with the market, income or cost approach, as specified in ASC 820, are used to measure fair value. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad areas: > Level 1 – inputs to the valuation methodology are quoted prices available in active markets for identical investments as of the reporting date. Level 2 – inputs to the valuation methodology are: - Quoted prices for similar assets or liabilities in active markets. - Quoted prices for identical or similar assets or liabilities in inactive markets. - Inputs other than quoted prices that are observable for the asset or liability. Level 3 – Inputs to the valuation methodology are unobservable inputs in situations where there is little or no market activity for the asset or liability, and the reporting entity makes estimates and assumptions related to the pricing of the asset or liability, including assumptions regarding risk. There were no transfers in or out of Level 3 during the year ending December 31, 2025. Investments as measured at fair value on a recurring basis by input type consisted of the following at December 31, 2025: | | Fair Value Measurement | | |--------------|-------------------------|-----------| | | Using Input Type | | | | Level 1 Level 2 Level 3 | Total | | Money Market | \$266,035 | \$266,035 | | Total | \$266,035 | \$266,035 | ### **Note (10) Employee Benefit Plan** The Company maintains a profit-sharing plan with a 401(k) provision covering all eligible employees. The Company contributes a percentage of salaries, matches participant contributions and may make discretionary contributions to the plan, subject to certain limitations as set forth in the plan agreement. Profit sharing expense was \$4,500 for the year ended December 31, 2025 and is included in employee compensation and benefits. {11}------------------------------------------------ ## **Note (11) Financial Instruments With Off-Balance-Sheet Risk** In the normal course of business, the Company's customer activities involve the execution and settlement of various customer securities transactions. These activities may expose the Company to off-balance-sheet risk in the event the customer or other broker is unable to fulfill its contracted obligations, and the Company has to purchase or sell the financial instrument underlying the contract at a loss. ## **Note (12) Concentrations of Credit Risk** The Company is engaged in various trading and brokerage activities in which counterparties primarily include broker-dealers, banks and other financial institutions. In the event counterparties do not fulfill their obligations, the Company may be exposed to risk. The risk of default depends on the creditworthiness of the counterparty or issuer of the instrument. It is the Company's policy to review, as necessary, the credit standing of each counterparty. ## **Note (13) Commitments and Contingencies** The Company has no other commitments or contingencies at December 31, 2025. ## **Note (14) Subsequent Events** The Company has performed an evaluation of subsequent events through the date the financial statements were available to be issued. The evaluation did not result in any subsequent events that required disclosures and/or adjustments. Source: SEC EDGAR via Adviser Search (https://search.stillhousedata.com).
