Significant Accounting Policies [Text Block]	NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The information included in the foregoing interim condensed consolidated financial statements is unaudited. In the opinion of management, all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the Company’s financial position and results of operations for the interim periods presented have been reflected herein. The results of operations for interim periods are not necessarily indicative of the results to be expected for the entire year. These interim condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and the notes thereto included in the 2024 Form 10-K. Subsequent events, if any, are evaluated through the date on which the financial statements are issued. Consolidation Policy The financial statements of Boston Omaha Corporation include the accounts of the Company and our consolidated subsidiaries, which are comprised of voting interest entities in which we have a controlling financial interest and variable interest entities for which we have determined that we are the primary beneficiary. All intercompany profits, losses, transactions, and balances have been eliminated in consolidation. Variable Interest Entities (VIEs) We determine whether an entity is a VIE and, if so, whether it should be consolidated by utilizing judgments and estimates that are inherently subjective. Our determination of whether an entity in which we hold a direct or indirect variable interest is a VIE is based on several factors, including whether the entity’s total equity investment at risk upon inception is sufficient to finance the entity’s activities without additional subordinated financial support. We make judgments regarding the sufficiency of the equity at risk based first on a qualitative analysis, and then a quantitative analysis, if necessary. We analyze any investments in VIEs to determine if we are the primary beneficiary. In evaluating whether we are the primary beneficiary, we evaluate our direct and indirect economic interests in the entity. A reporting entity is determined to be the primary beneficiary if it holds a controlling financial interest in the VIE. Determining which reporting entity, if any, has a controlling financial interest in a VIE is primarily a qualitative approach focused on identifying which reporting entity has both: (i) the power to direct the activities of a VIE that most significantly impact such entity’s economic performance; and (ii) the obligation to absorb losses or the right to receive benefits from such entity that could potentially be significant to such entity. Performance of that analysis requires the exercise of judgment. We consider a variety of factors in identifying the entity that holds the power to direct matters that most significantly impact the VIE’s economic performance including, but not limited to, the ability to direct operating decisions and activities. In addition, we consider the rights of other investors to participate in those decisions. We determine whether we are the primary beneficiary of a VIE at the time we become involved with a variable interest entity and reconsider that conclusion continually. We consolidate any VIE of which we are the primary beneficiary. Such VIEs consist of 24th Street Fund I and 24th Street Fund II, collectively “the 24th Street Funds,” and Fund One Boston Omaha Build for Rent LP, which we refer to as "BFR". Total assets of the consolidated VIEs included within our Condensed Consolidated Balance Sheets were approximately $32,000,000 and $48,700,000 as of September 30, 2025 and December 31, 2024, respectively. Total liabilities of the consolidated VIEs included within our Condensed Consolidated Balance Sheets were approximately $2,600 and $27,000 as of September 30, 2025 and December 31, 2024, respectively. As of September 30, 2025 and December 31, 2024, the aggregate fair value of the 24th Street Funds’ and BFR's investments in special purpose entities was approximately $30,500,000 and $46,900,000, respectively. During the first three quarters of 2025, the 24th Street Funds’ and BFR's investments in special purpose entities recognized other investment loss of approximately $6,600,000, and distributions to the funds of approximately $4,700,000. The assets of the consolidated VIEs may only be used to settle obligations of the same VIE. Our consolidated subsidiaries at September 30, 2025 include: Link Media Holdings, LLC which we refer to as “LMH” Link Media Alabama, LLC which we refer to as “LMA” Link Media Florida, LLC which we refer to as “LMF” Link Media Wisconsin, LLC which we refer to as “LMW” Link Media Georgia, LLC which we refer to as “LMG” Link Media Midwest, LLC which we refer to as “LMM” Link Media Omaha, LLC which we refer to as “LMO” Link Media Properties, LLC which we refer to as “LMP” Link Media Southeast, LLC which we refer to as “LMSE” Link Media Services, LLC which we refer to as “LMS” Link Billboards Oklahoma, LLC which we refer to as “LBO” General Indemnity Group, LLC which we refer to as “GIG” United Casualty and Surety Insurance Company which we refer to as “UCS” BOSS Bonds Insurance Agency, Inc., which we refer to as "BOSS Bonds", formerly known as South Coast Surety Insurance Services, LLC which we refer to as “SCS” Boston Omaha Investments, LLC which we refer to as “BOIC” Boston Omaha Asset Management, LLC which we refer to as “BOAM” Fund One Boston Omaha Build for Rent LP which we refer to as “BFR” BOAM BFR, LLC which we refer to as “BOAM BFR” BOC Business Services, LLC which we refer to as “BBS” BOC Yellowstone, LLC which we refer to as “BOC Yellowstone” BOC Yellowstone II, LLC which we refer to as “BOC Yellowstone II” 24th Street Asset Management LLC which we refer to as “24th Street” 24th Street Fund I, LLC which we refer to as “24th Street Fund I” 24th Street Fund II, LLC which we refer to as “24th Street Fund II” Boston Omaha Broadband, LLC which we refer to as “BOB” FIF AireBeam, LLC which we refer to as “AireBeam” Fiber Fast Homes, LLC which we refer to as “FFH” FIF Utah, LLC which we refer to as “FIF Utah” FIF St George, LLC which we refer to as “FIF St George” or "InfoWest" Revenues The majority of our advertising revenues are derived from contracts for advertising space on billboard structures and broadband internet services and are accounted for under Financial Accounting Standards Board, which we refer to as the “FASB,” Accounting Standards Codification, which we refer to as “ASC,” 606, Revenue from Contracts with Customers, and under ASC 842, Leases. Premium revenues derived from our insurance operations are subject to ASC 944, Financial Services – Insurance. Revenue Recognition Billboard Rentals We generate revenue from outdoor advertising through the leasing of advertising space on billboards. The terms of the contracts range from less than one month to three years and are generally billed monthly. Revenue for advertising space rental is recognized on a straight-line basis over the term of the contract. Advertising revenue is reported net of agency commissions. Agency commissions are calculated based on a stated percentage applied to gross billing revenue for operations. Payments received in advance of being earned are recorded as deferred revenue. Another component of billboard rentals consists of production services which include creating and printing advertising copy. Contract revenues for production services are accounted for under ASC 606, Revenue from Contracts with Customers. Revenues are recognized at a point in time upon satisfaction of the contract, which is typically less than one week. Practical expedients and exemptions: The Company is utilizing the following practical expedients and exemptions from ASC 606. We generally expense sales commissions when incurred because the amortization period is one year or less. These costs are recorded within costs of billboard revenues exclusive of depreciation and amortization. We do not disclose the value of unsatisfied performance obligations as the majority of our contracts with customers have an original expected length of less than one year. For contracts with customers which exceed one year, the future amount to be invoiced to the customer corresponds directly with the value to be received by the customer. Deferred Revenues We record deferred revenues when cash payments are received in advance of being earned or when we have an unconditional right to consideration before satisfying our performance obligation. The term between invoicing and when a payment is due is not significant. For certain services we require payment before the product or services are delivered to the customer. The balance of deferred revenue is considered short-term and will be recognized in revenue within twelve months. Premiums and Unearned Premium Reserves Premiums written are recognized as revenues based on a pro-rata daily calculation over the respective terms of the policies in-force. The cost of reinsurance ceded is initially written as prepaid reinsurance premiums and is amortized over the reinsurance contract period in proportion to the amount of insurance protection provided. Premiums ceded of $4,140,742 and $2,453,929 for the nine months ended September 30, 2025 and 2024, respectively, are included within “Premiums earned” in our Condensed Consolidated Statements of Operations. Commissions We generate revenue from commissions on surety bond sales and account for commissions under ASC 606. Insurance commissions are earned from various insurance companies based upon our agency agreements with them. We arrange with various insurance companies for the provision of a surety bond for entities that require a surety bond. The insurance company sets the price of the bond. The contract with the insurance company is fulfilled when the bond is issued by the insurance agency on behalf of the insurance company. The insurance commissions are calculated based upon a stated percentage applied to the gross premiums on bonds. Commissions are recognized at a point in time, on a bond-by-bond basis as of the policy effective date and are generally nonrefundable. Broadband Revenues Broadband revenue is derived principally from internet services and is recognized on a straight-line basis over the term of the contract in the period the services are rendered. Revenue received or receivable in advance of the delivery of services is included in deferred revenue. Supplemental Cash Flow Information There were no non-cash activities for the nine months ended September 30, 2025. For the nine months ended September 30, 2024, non-cash activities included stock issued for redeemable noncontrolling interest of $13,399,161, as well as an investment transferred as compensation for stock repurchased of $1,474,292.
