BUSINESS DESCRIPTION AND SUMMAR

BUSINESS DESCRIPTION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Business Description and Accounting Policies [Text Block]	NOTE 1 – BUSINESS DESCRIPTION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of Business Nuvera is a diversified communications company headquartered in New Ulm, Minnesota with more than 116 years of experience in the communications business. Our principal line of business is the operation of seven communications companies. Our businesses consist of connecting customers to our state-of-the-art, advanced fiber communications network, providing managed services, switched service and dedicated private lines, connecting customers to long distance service providers and providing many other services associated with our company. We also provide IPTV, CATV, Internet access services, including high-speed broadband access, and long distance service. We also install and maintain communications systems to the areas in and around our service territories in southern Minnesota and northern Iowa. Basis of Presentation and Principles of Consolidation Our accounting policies conform with GAAP and rules and regulations of the SEC and, where applicable, conform to the accounting principles as prescribed by federal and state telephone utility regulatory authorities. We presently give accounting recognition to the actions of regulators where appropriate in preparing general purpose financial statements for most public utilities. In general, the type of regulation covered by this statement permits rates (prices) for some services to be set at levels intended to recover the estimated costs of providing regulated services or products, including the cost of capital (interest costs and a provision for earnings on stockholders’ investments). Our consolidated financial statements report the financial condition and results of operations for Nuvera and its subsidiaries in one business segment: the Communications Segment. Inter-company transactions have been eliminated from the consolidated financial statements. Classification of Costs and Expenses Cost of services includes all costs related to delivery of communication services and products. These operating costs include all costs of performing services and providing related products including engineering, network monitoring and transportation costs. Selling, general and administrative expenses include direct and indirect selling expenses, customer service, billing and collections, advertising and all other general and administrative costs associated with our operations. Use of Estimates The preparation of our consolidated financial statements in conformity with GAAP requires our management to make estimates and judgements that affect the reported amounts of assets, liabilities, revenue and expenses, and the related disclosure of contingent assets and liabilities. The estimates and judgements used in the accompanying consolidated financial statements are based on our management’s evaluation of the relevant facts and circumstances as of the date of the financial statements. Actual results may differ from those estimates and assumptions. Revenue Recognition See Note 2 – “Revenue Recognition” for a discussion of our revenue recognition policies. Receivables As of December 31, 2021 and 2020, our consolidated receivables totaled $2,426,009 and $1,885,196, net of the allowance for doubtful accounts. We believe our receivables as of December 31, 2021 and 2020 are recorded at their fair value. As there may be exposure or risk with receivables, we routinely monitor our receivables and adjust the allowance for doubtful accounts when events occur that may potentially affect the collection of our receivables. Allowance for Doubtful Accounts We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. In making the determination of the appropriate allowance for doubtful accounts, we consider specific accounts, historical write-offs, changes in customer relationships, credit worthiness and concentrations of credit risk. Specific accounts receivable are written off once a determination is made that the account is uncollectible. Additional allowances may be required if the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments. The activity in our allowance for doubtful accounts includes the following: Year Ended December 31 2021 2020 Balance at beginning of year $ 160,000 $ 120,000 Additions charged to costs and expenses 155,763 185,251 Accounts written off, net of recoveries (235,763) (145,251) Balance at end of year $ 80,000 $ 160,000 Inventories Inventory includes parts, materials and supplies stored in our warehouses to support basic levels of service and maintenance as well as scheduled capital projects and equipment awaiting configuration for customers. Inventory also includes (i) parts and equipment shipped directly from vendors to customer locations while in transit and (ii) parts and equipment returned from customers that are being returned to vendors for credit. Our inventory value as of December 31, 2021 and 2020 was $5,357,380 and $2,965,960. We value inventory using the lower of cost or net realizable value. Similar to our allowance for doubtful accounts, we make estimates related to the valuation of inventory. As of December 31, 2021 and 2020, we had no inventory reserve. We adjust our inventory carrying value for estimated obsolescence or unmarketable inventory to the net realizable value based upon assumptions about future demand and market conditions. As market and other conditions change, we may establish additional inventory reserves at a time when the facts that give rise to a lower value are warranted. We use the first-in, first-out method of inventory costing for our non-retail inventory. We use the average cost method of inventory costing for our retail inventory. Property, Plant and Equipment We record impairment losses on long-lived assets used in operations when events and circumstances indicate the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets. In assessing the recoverability of long-lived assets, we compare the carrying value to the undiscounted future cash flows the assets are expected to generate. If the total of the undiscounted future cash flows is less than the carrying amount of the assets, we would write down those assets based on the excess of the carrying amount over the fair value of the assets. Fair value is generally determined by calculating the discounted future cash flows expected from those assets. Changes in these estimates could have a material adverse effect on the assessment of long-lived assets, thereby requiring a write-down of the assets. Write-downs of long-lived assets are recorded as impairment charges and are a component of operating expenses. We have reviewed our long-lived assets and concluded that no impairment charge on our long-lived assets is necessary. Property, plant and equipment additions are recorded net of any Broadband grants received. We use the group life method (mass asset accounting) to depreciate the assets of our communications companies. Communications plant acquired in a given year is grouped into similar categories and depreciated over the remaining estimated useful life of the group. When an asset is retired, both the asset and the accumulated depreciation associated with that asset are removed from the books. Due to rapid changes in technology, selecting the estimated economic life of communications plant and equipment requires a significant amount of judgment. We periodically review data on expected utilization of new equipment, asset retirement activity and net salvage values to determine adjustments to our depreciation rates. We have not made any significant changes to the lives of these assets in the two year period ended December 31, 2021. Goodwill and Intangible Assets We amortize our definite-lived intangible assets over their estimated useful lives. Customer relationships are amortized over fourteen to fifteen years, regulatory rights are amortized over fifteen years and trade names are amortized over three to five years. Intangible assets with finite lives are amortized over their respective estimated useful lives. In accordance with GAAP, goodwill and intangible assets with indefinite useful lives are not amortized, but tested for impairment at least annually. See Note 5 – “Goodwill and Intangibles” for a more detailed discussion of the intangible assets and goodwill. Our goodwill balance was $49,903,029 as of December 31, 2021 and 2020. In the fourth quarter of 2021 and 2020 we completed our annual impairment tests for existing acquired goodwill. This testing resulted in no impairment charges to goodwill at December 31, 2021 and 2020. Financial Derivative Instruments and Fair Value Measurements We have adopted the rules prescribed under GAAP for our financial assets and liabilities. GAAP includes a fair value hierarchy that is intended to increase consistency and comparability in fair value measurements and related disclosures. The fair value hierarchy is based on inputs to valuation techniques used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources, while unobservable inputs reflect a reporting entity’s pricing based upon its own market assumptions. The fair value hierarchy consists of the following three levels: Level 1: Inputs are quoted prices in active markets for identical assets or liabilities. Level 2: Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs that are derived principally from or corroborated by observable market data. Level 3: Inputs are derived from valuation techniques where one or more significant inputs or value drivers are unobservable. We have used financial derivative instruments to manage our overall cash flow exposure to fluctuations in interest rates. We accounted for derivative instruments in accordance with GAAP that requires derivative instruments to be recorded on the balance sheet at fair value. Changes in fair value of derivative instruments must be recognized in earnings unless specific hedge accounting criteria are met, in which case, the gains and losses are included in other comprehensive income rather than in earnings. We have entered into IRSAs with our lender, CoBank to manage our cash flow exposure to fluctuations in interest rates. These instruments are designated as cash flow hedges and are effective at mitigating the risk of fluctuations on interest rates in the marketplace. Any gains or losses related to changes in the fair value of these derivatives are accounted for as a component of accumulated other comprehensive income (loss) for as long as the hedge remains effective. The fair value of our IRSAs is discussed in Note 7 – “Interest Rate Swaps”. The fair value of our swap agreement was determined based on Level 2 inputs. Other Financial Instruments Other Investments - We conducted an evaluation of our investments in all of our investees in connection with the preparation of our audited financial statements at December 31, 2021. As of December 31, 2021, we believe the carrying value of our investments is not impaired. Debt – We estimate the fair value of our long-term debt based on the discounted future cash flows we expect to pay using current rates of borrowing for similar types of debt. Fair value of the debt approximates carrying value. Other Financial Instruments - Investments and Other Assets We are a co-investor with other communication companies in several partnerships and limited liability companies. These joint ventures make it possible to offer services to customers, including digital video services and fiber transport services that we would have difficulty offering on our own. These joint ventures also make it possible to invest in new technologies with a lower level of financial risk. We use the equity method of accounting for these investments that reflects original cost and recognition of our share of the net income or losses from the respective operations. See Note 16 – “Segment Information” for a listing of our investments. Investments in other companies that are not intended for resale and are not accounted for on the equity method of accounting are valued at fair value where there are readily determinable fair values. Investments in other companies that are not intended for resale and are not accounted for on the equity method of accounting are valued at cost where there are no readily determinable fair values. See Note 12 – “Other Investments” for additional information regarding our investments. Advertising Expense Advertising is expensed as incurred. Advertising expense charged to operations was $314,957 and $515,976 in 2021 and 2020. Interest During Construction We include an average cost of debt for the construction of plant in our communications plant accounts. Income Taxes We account for income taxes in accordance with GAAP, which requires an asset and liability approach to financial accounting and reporting for income taxes. Accordingly, deferred tax assets and liabilities arise from the difference between the tax basis of an asset or liability and its reported amount in the financial statements and operating and tax credit carryforwards. Deferred tax assets and liabilities are determined using enacted tax rates expected to apply to taxable income in the periods in which those temporary differences are expected to be recovered or settled. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We recognize interest and penalties related to income tax matters as income tax expense. Income tax expense or benefit is the tax payable or refundable, respectively, for the period plus or minus the change in deferred tax assets and liabilities during the period. GAAP requires us to recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more-likely-than-not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. See Note 8 – “Income Taxes” for additional information regarding income taxes. Collection of Taxes from Customers Sales, excise and other taxes are imposed on most of our sales to nonexempt customers. We collect these taxes from our customers and remit the entire amounts to governmental authorities. Our accounting policies dictate that we exclude these taxes collected and remitted from our revenues and expenses. Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash investments and receivables. We deposit our cash investments in high credit quality financial institutions accounts which, at times, may exceed federally insured limits. We have not experienced any losses in these accounts and do not believe we are exposed to any significant credit risk. Concentrations of credit risk with respect to trade receivables are limited due to our large number of customers. Earnings and Dividends Per Share Basic and diluted net income per share are calculated as follows: Year Ended December 31, 2021 Year Ended December 31, 2020 Basic Diluted Basic Diluted Net Income $ 12,251,921 $ 12,251,921 $ 9,835,812 $ 9,835,812 Weighted-average common 5,207,759 5,217,722 5,194,006 5,199,696 Net income per share $ 2.35 $ 2.35 $ 1.89 $ 1.89 The weighted-average shares outstanding, basic and diluted, are calculated as follows: Year Ended December 31, 2021 Year Ended December 31, 2020 Basic Diluted Basic Diluted Weighted-average common 5,207,759 5,207,759 5,194,006 5,194,006 Potentially Dilutive RSU's - 9,963 - 5,690 Weighted-average common 5,207,759 5,217,722 5,194,006 5,199,696 Nuvera’s BOD reviews quarterly dividend declarations based on our anticipated earnings, capital requirements and our operating and financial conditions. Recent Accounting Developments In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-04, “Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” ASU 2020-04 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. In January 2021, the FASB issued ASU No. 2101-01, “Reference Rate Reform (Topic 848): Scope.” ASU 2021-01 clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. ASU 2020-04 and ASU 2021-01 are both elective and are effective upon issuance through December 31, 2022. The Company is evaluating the impact this update will have on our consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU 2017-04, “Intangibles – Goodwill and other (Topic 350): Simplifying the Test for Goodwill Impairment.” ASU 2017-04 simplifies the subsequent measurement of goodwill by eliminating the second step of the goodwill impairment test. The second step measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under ASU 2017-04, a company will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. ASU 2017-04 will be applied prospectively and is effective for annual or interim goodwill impairment tests in the fiscal years beginning January 1, 2021. The Company adopted ASU 2017-04 on January 1, 2021, and the adoption of the standard did not have a material effect on our financial position, results of operations or cash flows . In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires entities to use a new forward-looking, expected loss model to estimate credit losses. It also requires additional disclosures relating to the credit quality of trade and other receivables, including information relating to management’s estimate of credit allowances. The Company is required to adopt ASU 2016-13 for fiscal periods beginning after December 15, 2022, including interim periods within that fiscal year. Early adoption as of December 15, 2018, is permitted. Management is evaluating the impact the adoption of ASU 2016-13 will have on the Company’s financial statements (if any). We have reviewed all other significant newly issued accounting pronouncements and determined that they are either not applicable to our business or that no material effect is expected on our financial position and results of operations.

REVENUE RECOGNITION

REVENUE RECOGNITION	12 Months Ended
	Dec. 31, 2021
Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	NOTE 2 – REVENUE RECOGNITION The Company recognizes revenue based on the following single principles-based, five-step model that is applied to all contracts with customers. These steps include (1) identify the contract(s) with the customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when each performance obligation is satisfied. Our revenue contracts with customers may include a promise or promises to deliver services such as broadband, video or voice services. Promised services are considered distinct as the customer can benefit from the services either on their own or together with other resources that are readily available to the customer and the Company’s promise to transfer service to the customer is separately identifiable from other promises in the contract. The Company accounts for services as separate performance obligations. Each service is considered a single performance obligation as it is providing a series of distinct services that are substantially the same and have the same pattern of transfer. The transaction price is determined at contract inception and reflects the amount of consideration to which we expect to be entitled in exchange for transferring service to the customer. This amount is generally equal to the market price of the services promised in the contract and may include promotional or bundling discounts. The majority of our prices are based on tariffed rates filed with regulatory bodies or standard company price lists. The transaction price excludes amounts collected on behalf of third parties such as sales taxes and regulatory fees. Conversely, nonrefundable up-front fees, such as service activation and set-up fees, which are immaterial to our overall revenues, are included in the transaction price. In determining the transaction price, we consider our enforceable rights and obligations within the contract. We do not consider the possibility of a contract being cancelled, renewed or modified, which is consistent with ASC 606-10-32-4. The transaction price is allocated to each performance obligation based on the standalone selling price of the service, net of the related discount, as applicable. Revenue is recognized when performance obligations are satisfied by transferring service to the customer as described below. Significant Judgments The Company often provides multiple services to a customer. Provision of CPE and additional service tiers may have a significant level of integration and interdependency with the subscription voice, video, Internet, or connectivity services. Judgement is required to determine whether provision of CPE, installation services, and additional service tiers are considered distinct and accounted for separately, or not distinct and accounted for together with the subscription services. Allocation of the transaction price to the distinct performance obligations in bundled service subscriptions requires judgement. The transaction price for a bundle of services is frequently less than the sum of standalone selling prices of each individual service. Bundled discounts are allocated proportionally to the selling price of each individual service within the bundle. Standalone selling prices for the Company’s services are directly observable. Disaggregation of Revenue The following table summarizes revenue from contracts with customers for the years ended December 31, 2021 and 2020: Twelve Months Ended December 31, 2021 2020 Voice Service¹ $ 6,999,201 7,594,617 Network Access¹ 5,714,304 6,229,549 Video Service ¹ 12,595,399 12,215,923 Data Service ¹ 23,368,569 21,416,969 Directory² 699,122 794,552 Other Contracted Revenue³ 2,611,230 2,403,107 Other 4 1,215,635 1,292,700 Revenue from customers 53,203,460 51,947,417 Subsidy and other revenue 5 12,634,061 12,963,654 Total revenue $ 65,837,521 $ 64,911,071 ¹ Month-to-Month contracts billed and consumed in the same month. ² Directory revenue is contracted annually, however, this revenue is recognized ³ This includes long-term contracts where the revenue is recognized monthly over 4 This includes CPE and other equipment sales. 5 This includes governmental subsidies and lease revenue outside the scope of ASC 606. For the year ended December 31, 2021, approximately 78.96% of our total revenue was from month-to-month and other contracted revenue from customers. Approximately 19.19% of our total revenue was from revenue sources outside of the scope of ASC 606. The remaining 1.85% of total revenue was from other sources including CPE and equipment sales and installation. For the year ended December 31, 2020, approximately 78.04% of our total revenue was from month-to-month and other contracted revenue from customers. Approximately 19.97% of our total revenue was from revenue sources outside of the scope of ASC 606. The remaining 1.99% of total revenue was from other sources including CPE and equipment sales and installation. A significant portion of our revenue is derived from customers who may generally cancel their subscriptions at any time without penalty. As such, the amount of revenue related to unsatisfied performance obligations is not necessarily indicative of the future revenue to be recognized from our existing customer base. Revenue from customers with a contractually specified term and non-cancelable service period will be recognized over the term of such contracts, which is generally 3 to 10 years for these types of contracts. Nature of Services Revenues are earned from our customers primarily through the connection to our fiber networks, digital and commercial TV programming, Internet services (high-speed broadband), and hosted and managed services. Revenues for these services are billed based on set rates for monthly service or based on the amount of time the customer is utilizing our facilities. The revenue for these services is recognized over time as the service is rendered. Voice Service – We receive recurring revenue for basic local services that enable end-user customers to make and receive telephone calls within a defined local calling area for a flat monthly fee. In addition to subscribing to basic local telephone services, our customers may choose from multiple voice service plans with a variety of custom calling features such as call waiting, call forwarding, caller identification and voicemail. Our VOIP digital phone service is also available as an alternative to the traditional telephone line. Customers may generally cancel their subscriptions at any time without penalty. Each subscription service provided is accounted for as a distinct performance obligation and revenue is recognized over a one-month service period as the subscription services are delivered. Other optional services purchased by the customer are generally accounted for as a distinct performance obligation when purchased and revenue is recognized when the service is provided. Network Access – We provide access services to other communication carriers for the use of our facilities to terminate or originate long distance calls on our network. Additionally, we bill monthly SLCs to substantially all of our customers for access to the public switched network. These monthly SLCs are regulated and approved by the FCC. In addition, network access revenue is derived from several federally administered pooling arrangements designed to provide support and distribute funding to us. Revenues earned from other communication carriers accessing our network are based on the utilization of our network by these carriers as measured by minutes of use on the network or special access to the network by the individual carriers on a monthly basis. Revenues are billed at tariffed access rates for both interstate and intrastate calls and are recognized into revenue monthly based on the period the access was provided. The NECA pools and redistributes the SLCs to various communication providers through the CAF. These revenues are earned and recognized into revenue on a monthly basis. Any adjustments to these amounts received by NECA are adjusted for in revenue upon receipt of the adjustment. Video Service – We provide a variety of enhanced video services on a monthly recurring basis to our customers. We also receive monthly recurring revenue from our subscribers for providing commercial TV programming in competition with CATV, satellite dish TV and off-air TV service providers. We serve twenty-two communities with our IPTV services and five communities with our CATV services. Customers may generally cancel their subscriptions at any time without penalty. Each subscription service provided is accounted for as a distinct performance obligation and revenue is recognized over a one-month service period as the subscription services are delivered. Other optional services purchased by the customer are generally accounted for as a distinct performance obligation when purchased and revenue is recognized when the service is provided. Data Service – We provide high speed Internet to business and residential customers depending on the nature of the network facilities that are available, the level of service selected and the location. Our revenue is earned based on the offering of various flat packages based on the level of service, data speeds and features. We also provide e-mail and managed services, such as web hosting and design, on-line file back up and on-line file storage. Data customers may generally cancel their subscriptions at any time without penalty. Each subscription service provided is accounted for as a distinct performance obligation and revenue is recognized over a one-month service period as the subscription services are delivered. Other optional services purchased by the customer are generally accounted for as a distinct performance obligation when purchased and revenue is recognized when the service is provided. Directory – Our directory publishing revenue in our telephone directories recurs monthly and is recognized into revenue on a monthly basis. Other Contracted Revenue - Managed services and certain other data customers include fiber-delivered communications and managed information technology solutions to mainly business customers, as well as high-capacity last-mile data connectivity services to wireless and wireline carriers. Services are primarily offered on a subscription basis with a contractually specified and non-cancelable service period. The non-cancelable contract terms for these customers generally range from 3 to 10 years. Each subscription service provided is accounted for as a distinct performance obligation and revenue is recognized ratably over the contract period as the subscription services are delivered. These services are billed as monthly recurring charges to customers. Other – We also generate revenue from the sales, service and installation of CPE and other services. Sales and service of CPE are billed and recognized into revenue once the sale or service is complete or delivered. These sales and services are generally short-term in nature and are completed within one month. Other revenues are immaterial to our total revenues. Subsidy and Other Revenue outside the Scope of ASC 606 – We receive subsidies from governmental entities to operate and expand our fiber networks. In addition, we have revenue from leasing arrangements. Both of these revenue streams are outside of the scope of ASC 606. Interstate access rates are established by a nationwide pooling of companies known as the NECA. The FCC established NECA in 1983 to develop and administer interstate access service rates, terms and conditions. Revenues are pooled and redistributed on the basis of a company's actual or average costs. There has been a change in the composition of interstate access charges in recent years, shifting more of the charges to the end user and reducing the amount of access charges paid by IXC’s. We believe this trend will continue. Intrastate access rates are filed with state regulatory commissions in Minnesota and Iowa. The Company currently receives funding based on the A-CAM as described below, with the exception of Scott-Rice, which receives funding from the FUSF. Scott-Rice’s settlements from the pools are based on nationwide average schedules, which includes the pooling and redistribution of revenues based on a company’s actual or average costs as described below. A-CAM As described above, with the exception of Scott-Rice, the remainder of our companies receive funding from A-CAM. Per the FCC Public Notice DA 19-115, the Company receives A-CAM support and has corresponding service deployment obligations under that program. The Company annually receives (i) $596,084 for its Iowa operations and (ii) $8,354,481 for its Minnesota operations. The Company will receive the revised A-CAM offer for a period of 10 years, which started in 2019. The Company uses the funding that it receives through the A-CAM program to meet its defined broadband build-out obligations, which the Company is currently completing. Accounts Receivable, Contract Assets and Contract Liabilities The following table provides information about our receivables, contracts assets and contract liabilities from revenue contracts with our customers: Year Ended December 31, 2021 2020 Accounts receivable, net $ 1,681,738 $ 1,142,476 Contract assets 662,437 421,557 Contract liabilities 602,007 670,988 Accounts Receivable A receivable is recognized in the period the Company provides goods and services when the Company’s right to consideration is unconditional. Payment terms on invoiced amounts are generally 30-60 days. Contract Assets Contract assets include costs that are incremental to the acquisition of a contract. Incremental costs are those that result directly from obtaining a contract or costs that would not have been incurred if the contract had not been obtained, which primarily relates to sales commissions. We defer and amortize these costs over the expected customer life as the contract obligations are satisfied. We determined that the expected customer life is the expected period of benefit as the commission on the renewal contact is commensurate with the commission on the initial contract. During the years ended December 31, 2021 and 2020, the Company recognized expenses of $193,736 and $82,684, respectively, related to deferred contract acquisition costs. Short-term contract assets are included in current assets under prepaid expenses and other current assets. Long-term contract assets are included in investments and other assets under other assets. Contract Liabilities Contract liabilities include deferred revenues related to advanced payments for services and nonrefundable, upfront service activation and set-up fees, which under the new standard are generally deferred. In addition, contract liabilities include customer deposits that are not recognized into revenue, but are instead returned to the customer after a holding period. Short-term contract liabilities include deferred revenues for advanced payments for managed services and other long-term contracts. This includes the current portion of the deferred revenues that will be recognized monthly within one year. Short-term contract liabilities are included in current liabilities under other accrued liabilities. Long-term contract liabilities include deferred revenues for advanced payments for managed services and other long-term contracts. This includes the portion longer than one year and the corresponding deferred revenues are recognized into revenue on a monthly basis based on the term of the contract. Long-term contract liabilities are included in noncurrent liabilities under other accrued liabilities. During the years ended December 31, 2021 and 2020, the Company recognized revenues of $326,887 and $251,339, respectively, related to deferred revenues. Performance Obligations ASC 606, Revenue from Contracts with Customers, requires that the Company disclose the aggregate amount of the transaction price that is allocated to remaining performance obligations that are unsatisfied as of December 31, 2021. The guidance provides certain practical expedients that limit this requirement. The service revenue contracts of the Company meet the following practical expedients provided by ASC 606: 1. 2. The Company has elected these practical expedients. Performance obligations related to our service revenue contracts are generally satisfied over time. For services transferred over time, revenue is recognized based on amounts invoiced to the customer as the Company has concluded that the invoice amount directly corresponds with the value of services provided to the customer. Management considers this a faithful depiction of the transfer of control as services are substantially the same and have the same pattern of transfer over the life of the contract. As such, revenue related to unsatisfied performance obligations that will be billed in future periods has not been disclosed.

Lessee, Operating Leases [Text Block]	NOTE 3 – LEASES Under FASB’s ASU 2016-02, “Leases,” which, together with its related clarifying ASUs, provided revised guidance for lease accounting and related disclosure requirements and established a right-to-use (ROU) model that requires lessees to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition. The ASU also requires disclosures to allow financial statement users to better understand the amount, timing and uncertainty of cash flows arising from leases. These disclosures include qualitative requirements, providing additional information about the amounts recorded in the financial statements. The following table includes the ROU and operating lease liabilities as of December 31, 2021 and 2020. Right of Use Asset Balance December 31, 2021 Balance December 31, 2020 Operating Lease Right-Of-Use Assets $ 1,154,293 $ 1,211,707 Operating Lease Liability Balance Balance December 31, 2020 Short-Term Operating Lease Liability $ 283,167 $ 243,218 Long-Term Operating Lease Liability 905,528 993,596 Total $ 1,188,695 $ 1,236,814 Maturity analysis under these lease agreements are as follows: Maturity Analysis 2022 $ 347,778 2023 348,708 2024 236,948 2025 120,881 2026 71,023 Thereafter 309,800 Total 1,435,138 Less Imputed interest (246,443) Present Value of Operating Leases $ 1,188,695 We amortize our leases over the shorter of the term of the lease or the useful life of the asset.

The composite depreciation rates on communications plant and equipment for the two years ended December 31, 2021 and 2020, respectively, were 4.1% and 4.3%. Other property and video plant is depreciated over estimated useful lives of three to twenty-five years.

GOODWILL AND INTANGIBLES

GOODWILL AND INTANGIBLES	12 Months Ended
	Dec. 31, 2021
Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets Disclosure [Text Block]	NOTE 5 - GOODWILL AND INTANGIBLES We account for goodwill and other intangible assets under GAAP. Under GAAP, goodwill and intangible assets with indefinite useful lives are not amortized, but are instead tested for impairment (i) on at least an annual basis and (ii) when changes in circumstances indicate that the fair value of goodwill may be below its carrying value. These circumstances include, but are not limited to (i) a significant adverse change in the business climate, (ii) unanticipated competition or (iii) an adverse action or assessment by a regulator. Determining impairment involves estimating the fair value of a reporting unit using a combination of (i) the income or DCF approach and (ii) the market approach that utilizes comparable companies’ data. If the carrying amount of a reporting unit exceeds its fair value, the amount of the impairment loss must be measured. The impairment loss is calculated by comparing the implied fair value of the reporting unit’s goodwill to its carrying amount. In calculating the implied fair value of the reporting unit’s goodwill, the fair value of the reporting unit is allocated to all of the assets and liabilities of the reporting unit. The excess of the fair value of a reporting unit over the amount assigned to its other assets and liabilities is the implied value of goodwill. We recognize impairment loss when the carrying amount of goodwill exceeds its implied fair value. Our goodwill totaled $49,903,029 at December 31, 2021 and 2020. In 2021 and 2020, we engaged an independent valuation firm to aid in the completion of our annual impairment testing for existing goodwill. For 2021 and 2020, the testing results indicated no impairment charge to goodwill as the determined fair value was sufficient to pass the impairment test. Our intangible assets subject to amortization consist of acquired customer relationships, regulatory rights and trade names. We amortize intangible assets with finite lives over their respective estimated useful lives. Identifiable intangible assets that are subject to amortization are evaluated for impairment. In addition, we periodically reassess the carrying value, useful lives and classifications of our identifiable intangible assets. The components of our identified intangible assets are as follows: December 31, 2021 December 31, 2020 Gross Carrying Amount Gross Carrying Amount Useful Lives Accumulated Amortization Accumulated Amortization Definite-Lived Intangible Assets Customers Relationships 14-15 yrs $ 42,878,445 $ 28,806,055 $ 42,878,445 $ 25,811,014 Regulatory Rights 15 yrs 4,000,000 3,733,299 4,000,000 3,466,635 Trade Name 3-5 yrs 310,106 211,444 310,106 149,423 Indefinitely-Lived Intangible Assets Video Franchise 3,000,000 - 3,000,000 - Spectrum 877,814 - 877,814 - Total $ 51,066,365 $ 32,750,798 $ 51,066,365 $ 29,427,072 Net Identified Intangible Assets $ 18,315,567 $ 21,639,293 Amortization expense related to the definite-lived assets was $3,323,726 for 2021 and $3,323,771 for 2020.

Debt Disclosure [Abstract]
Long-term Debt [Text Block]	NOTE 6 - LONG-TERM DEBT We have a MLA with CoBank. Nuvera and its respective subsidiaries also have security agreements under which substantially all the assets of Nuvera and its respective subsidiaries have been pledged to CoBank as collateral. In addition, Nuvera and its respective subsidiaries have guaranteed all the obligations under the credit facility. These mortgage notes are required to be paid in quarterly installments covering principal and interest, beginning in September 2018 and maturing on July 31, 2025. Secured Credit Facility: MLA RX0583 ▪ RX0583(A)-T4 - $64,550,000 term note with interest payable quarterly. Final maturity date of this note is July 31, 2025. Twenty-eight quarterly principal payments of $1,152,600 are due commencing September 30, 2018 through June 30, 2025. A final balloon payment of $32,265,785 is due at maturity of this note on July 31, 2025. ▪ RX0583(A)-T5 - $10,000,000 revolving note with interest payable quarterly. Final maturity date of this note is July 31, 2025. We currently have drawn $1,077,589 on this revolving note as of December 31, 2020. RX0583(A)-T4 and RX0583(A)-T5 initially bear interest at a “LIBOR Margin” rate equal to 3.25 percent over the applicable LIBOR rate. The LIBOR Margin decreases as our “Leverage Ratio” decreases. We generally use variable-rate debt to finance our operations, capital expenditures and acquisitions. These variable-rate debt obligations expose us to variability in interest payments due to changes in interest rates. The terms of our credit facility with CoBank require that we enter into interest rate agreements designed to protect us against fluctuations in interest rates, in an aggregate principal amount and for a duration determined under the credit facility. As described in Note 7 – “Interest Rate Swaps,” on August 1, 2018 we entered into an IRSA with CoBank covering 25 percent of our existing debt balance or $16,137,500 of our aggregate indebtedness to CoBank on August 1, 2018. As of December 31, 2021, our IRSA covered $12,103,400, with a weighted average rate of 5.27%. As described in Note 7 – “Interest Rate Swaps,” on August 29, 2019 we entered into a second IRSA with CoBank covering an additional $42,000,000 of our aggregate indebtedness to CoBank at August 29, 2019. As of December 31, 2021, our IRSA covered $33,923,670, with a weighted average rate of 3.50%. Our remaining debt of $10.9 million ($8.9 million available under the revolving credit facilities and $2.0 million currently outstanding) remains subject to variable interest rates at an effective weighted average interest rate of 2.36%, as of December 31, 2021. Our loan agreements include restrictions on our ability to pay cash dividends to our stockholders. However, we are allowed to pay dividends (a) (i) in an amount up to $2,700,000 in any year if our “Total Leverage Ratio,” that is, the ratio of our “Indebtedness” to “EBITDA” (earnings before interest, taxes, depreciation and amortization – as defined in the loan documents), is greater than 2.00 to 1.00, and (ii) in any amount if our Total Leverage Ratio is less than 2.00 to 1.00, and (b) in either case, if we are not in default or potential default under the loan agreements. On December 31, 2020, our Total Leverage Ratio fell below 2.00, thus eliminating any restrictions on our ability to pay cash dividends to our stockholders. Our current Total Leverage Ratio as of December 31, 2021, is 1.83. Our credit facility requires us to comply with specified financial ratios and tests. These financial ratios include total leverage ratio, debt service coverage ratio, equity to total assets ratio and annual maximum aggregate capital expenditures. As of December 31, 2021, we were in compliance with all the stipulated financial ratios in our loan agreements. There are security and loan agreements underlying our current CoBank credit facility that contain restrictions on our distributions to stockholders and investment in, or loans, to others. Also, our credit facility contains restrictions that, among other things, limits or restricts our ability to enter into guarantees and contingent liabilities, incur additional debt, issue stock, transact asset sales, transfers or dispositions, and engage in mergers and acquisitions, without CoBank approval. On April 16, 2020, Nuvera received a $2,889,000 loan under the SBA’s PPP, which was established as part of the COVID-19 CARES Act. The PPP Loan was unsecured and was evidenced by a note in the favor of Citizens as the lender. The interest rate on the Note was 1.0% per annum. Payments of principal and interest were deferred for 180 days from the date of the Note (the deferral period). The PPP provided a mechanism for forgiveness of up to the full amount borrowed as long as Nuvera used the loan proceeds during the 24-week period after the loan origination for eligible purposes, including U.S. payroll costs, certain benefit costs, rent and utilities costs, and maintained its employment and compensation levels, subject to certain other requirements and limitations. The amount of the loan forgiveness was subject to reduction, among other things, if Nuvera terminated employees or reduced salaries or wages during the 24-week period. Any unforgiven portion of the PPP Loan was payable over a two-year term, with payments deferred during the deferral period. Nuvera was permitted to prepay the Note at any time without payment of any premium. The Note contained customary events of material defaults, including, among others, those relating to failure to make a payment, bankruptcy, other indebtedness, breaches of representations, and material adverse changes. The Company adhered to all guidelines under the terms of the Note and applied for debt forgiveness in August, 2020. On February 3, 2021, the Company was notified by Citizens, the lender on the Company’s PPP Loan that Citizens had received payment in full from the United States federal government for the amount of the Company’s PPP Loan and the Company’s PPP Loan had been fully forgiven. We recognized a gain on the forgiveness of $2,912,433, which included the original amount of the loan plus accrued interest in the quarter ended March 31, 2021. Long-term debt is as follows: 2021 2020 Secured seven-year credit facility to CoBank, ACB, amortizing in quarterly installments of $1,152,600 (beginning on September 30, 2018), plus a notional variable rate of interest through July 31, 2025. $ 46,902,185 $ 51,512,585 Secured seven-year revolving credit facility of up to $10,000,000 to CoBank, ACB, plus a notional variable rate of interest through July 31, 2025. 1,077,589 - Unsecured two-year SBA PPP Loan of $2,889,000 at 1% per annum from Citizens Bank Minnesota received April 16, 2020.

INTEREST RATE SWAPS

INTEREST RATE SWAPS	12 Months Ended
	Dec. 31, 2021
Disclosure Text Block Supplement [Abstract]
Financial Instruments Disclosure [Text Block]	NOTE 7 – INTEREST RATE SWAPS We assess interest rate cash flow risk by continually identifying and monitoring changes in interest rate exposures that may adversely affect expected future cash flows and by evaluating hedging opportunities. We generally use variable-rate debt to finance our operations, capital expenditures and acquisitions. These variable-rate debt obligations expose us to variability in interest payments due to changes in interest rates. The terms of our credit facility with CoBank required that we enter into interest rate agreements designed to protect us against fluctuations in interest rates, in an aggregate principal amount and for a duration determined under the credit facility. To meet this objective, we have entered into an IRSA with CoBank covering 25 percent of our existing outstanding debt balance or $16,137,500 of our aggregate indebtedness to CoBank at August 1, 2018. The swap effectively locked in the interest rate on 25 percent of our variable-rate debt through July 2025. Under this IRSA, we have changed the variable-rate cash flow exposure on the debt obligations to fixed cash flows. Under the terms of the IRSA, we pay a fixed contractual interest rate and (i) make an additional payment if the LIBOR variable rate payment is below a contractual rate or (ii) receive a payment if the LIBOR variable rate payment is above the contractual rate. On August 29, 2019, we entered into a second IRSA with CoBank covering an additional $42,000,000 of our aggregate indebtedness to CoBank on August 29, 2019. The swap effectively locked in a significant portion of our variable-rate debt through July 2025. Under this IRSA, we have changed the variable rate cash flow exposure on the debt obligations to fixed cash flows. Under the terms of the IRSA, we pay a fixed contractual interest rate and (i) make an additional payment if the LIBOR variable rate payment is below a contractual rate or (ii) receive a payment if the LIBOR variable rate payment is above the contractual rate. Each month, we make interest payments to CoBank under its loan agreements based on the current applicable LIBOR Rate plus the contractual LIBOR margin then in effect with respect to the loan, without reflecting our IRSAs. At the end of each calendar month, CoBank adjusts our aggregate interest payments based on the difference, if any, between the amounts paid by us during the month and the current effective interest rate. Net interest payments are reported in our consolidated income statement as interest expense. As of December 31, 2021 we had the following IRSA in effect. Loan # Maturity Date Notional Amount Current Effective Interest Rate (1) RX0583-T4 07/31/2025 $12,103,400 5.27% (LIBOR Rate of 3.02% plus 2.25% LIBOR Margin) RX0583-T4 07/31/2025 $33,923,670 3.50% (LIBOR Rate of 1.25% plus 2.25% LIBOR Margin) (1) As described in Note 6 – “Long-Term Debt,” the notes above initially bears interest at a LIBOR rate determined by the maturity of the note, plus a “LIBOR Margin” rate equal to a maximum of 3.25% according to the individual secured credit facility. The LIBOR Margin decreases as the borrower’s “Leverage Ratio” decreases. The “Current Effective Interest Rate” in the table reflects the rate we pay giving effect to the swaps. Our IRSAs under our credit facilities both qualify as cash flow hedges for accounting purposes under GAAP. We reflect the effect of these hedging transactions in the financial statements. The unrealized gain/loss is reported in other comprehensive income. If we terminate our IRSAs, the cumulative change in fair value at the date of termination would be reclassified from accumulated other comprehensive income, which is classified in stockholders’ equity, into earnings on the consolidated statements of income. The fair value of the Company’s IRSAs were determined based on valuations received from CoBank and were based on the present value of expected future cash flows using discount rates appropriate with the terms of the IRSAs. The fair value indicates an estimated amount we would be required to pay if the contracts were canceled or transferred to other parties. On December 31, 2021, the fair value liability of these swaps was $883,365, which has been recorded net of deferred tax benefit of $252,112, resulting in the $631,253 in accumulated other comprehensive loss. At December 31, 2020, the fair value liability of these swaps were $2,721,118, which has been recorded net of deferred tax benefit of $776,607, resulting in the $1,944,511 in accumulated other comprehensive income.

As required by GAAP, we recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more-likely-than-not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. As of December 31, 2021 and 2020 we had $38,673 and $44,155 of unrecognized tax benefits that if recognized would affect the tax rate. We do not expect the total amount of unrecognized tax benefits to materially change over the next 12 months. A reconciliation of the beginning and ending amount of total unrecognized benefits for the years ended December 31, 2021 and 2020 are as follows: 2021 2020 Balance, beginning of year $ 44,155 $ - Increases related to prior year tax positions - 44,155 Decreases related to prior year tax positions (5,482) - Increases related to current year tax positions - - Settlements - - Balance, end of year $ 38,673 $ 44,155 We are primarily subject to United States, Minnesota, Iowa, Nebraska, North Dakota and Wisconsin income taxes. Tax years subsequent to 2017 remain open to examination by federal and state tax authorities. We are currently undergoing an examination by the State of Minnesota. We do not expect the results of the examination to have a material effect on our ongoing financial statements. Our policy is to recognize interest and penalties related to income tax matters as income tax expense. As of December 31, 2021 and 2020 we had $4,102 and $3,208 accrued interest that related to income tax matters. The differences between the statutory federal tax rate and the effective tax rate were as follows: 2021 2020 Statutory Tax Rate 21.00 % 21.00 % Effect of: State Income Taxes Net of Federal Tax Benefit 6.72 8.79 Forgiveness of PPP Loan (3.83) - Permanent Differences and Other, Net (0.54) (0.57) Effective tax rate 23.35 % 29.22 % Our effective income tax rate for the year ended December 31, 2021 was lower than the effective income tax rate for the year ended December 31, 2020 primarily due to the PPP loan forgiveness not being taxable at the federal and state level. Deferred income taxes and unrecognized tax benefits reflected in our consolidated balance sheets are summarized as follows: 2021 2020 Deferred Tax Assets Accrued Expenses $ (415,464) $ (465,304) Deferred Compensation (131,412) (263,355) Other (122,939) (131,291) Unrealized Loss on SWAP (252,112) (776,730) State NOL - (52,854) Leases (321,530) (353,043) Total Deferred Tax Assets (1,243,457) (2,042,577) Deferred Tax Liabilities Fixed Assets 14,921,908 12,306,391 Intangible Assets 4,124,935 5,049,532 Investments 1,180,314 1,208,856 Contract Assets 189,089 120,331 Leases 311,711 345,876 Total Deferred Tax Liabilities: 20,727,957 19,030,986 Total Net Deferred Taxes $ 19,484,500 $ 16,988,409

These joint ventures make it possible to offer services to customers, including digital video services and fiber transport services that we would have difficulty offering on our own. These joint ventures also make it possible to invest in new technologies with a lower level of financial risk. We recognize income and losses from these investments on the equity method of accounting. For a listing of our investments, see Note 16 – “Segment Information.” The FASB requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. As of December 31, 2021 we had not recorded any gains or losses on our investments. As of December 31, 2020, we recorded a gain on one of our investments of $47,640.

The shareholders of the Company approved the Plan at the May 25, 2017 Annual Meeting of Shareholders. The Plan enables the Company to grant stock incentive awards to current and new employees, including officers, and to Board members and service providers. The Plan permits stock incentive awards in the form of options (incentive and non-qualified), stock appreciation rights, restricted stock, RSUs, performance stock, performance units, and other awards in stock or cash. The Plan permits the issuance of up to 625,000 shares of our Common Stock in any of the above stock awards. As of March 16, 2022, 559,156 shares remain available to be issued under the Plan. Starting in 2017 and each subsequent year following 2017, our BOD and Compensation Committee granted awards to the Company’s executive officers under the Plan. We recognize share-based compensation expense for these RSUs over the vesting period of the RSUs which is determined by our BOD. Forfeitures of RSU’s are accounted for as they occur. Each executive officer received or may receive time-based RSUs and performance based RSUs. The time-based RSUs are computed as a percentage of the executive officer’s base salary based on the closing price of Company common stock on a date set by the BOD and will vest over a three-year period based on the executive officer being employed by the Company on the vesting date. The performance based RSUs are also computed as a percentage of the executive officer’s base salary based on the closing price of Company common stock on a date set by the BOD and will vest over a three-year period based on the Company attaining an average Return on Invested Capital (ROIC) over that three-year period. The ROIC target is set by the BOD. Executive officers may earn more or less performance based RSU’s based on if the actual ROIC over the time period is more or less than target. Upon vesting of either time-based or performance based RSUs, the executive officers will be able to receive Common Stock in the Company in exchange for the RSUs.

Our principal line of business is the operation of seven communications companies. Our businesses consist of connecting customers to our state-of-the-art, advanced fiber communications network, providing managed services, switched service and dedicated private lines, connecting customers to long distance service providers and providing many other services associated with our company. We also provide IPTV, CATV, Internet access services, including high-speed broadband access, and long distance service. We also install and maintain communications systems to the areas in and around our service territories in southern Minnesota and northern Iowa.
Basis Of Presentation And Principles Of Consolidation [Policy Text Block]	Basis of Presentation and Principles of Consolidation Our accounting policies conform with GAAP and rules and regulations of the SEC and, where applicable, conform to the accounting principles as prescribed by federal and state telephone utility regulatory authorities. We presently give accounting recognition to the actions of regulators where appropriate in preparing general purpose financial statements for most public utilities. In general, the type of regulation covered by this statement permits rates (prices) for some services to be set at levels intended to recover the estimated costs of providing regulated services or products, including the cost of capital (interest costs and a provision for earnings on stockholders’ investments). Our consolidated financial statements report the financial condition and results of operations for Nuvera and its subsidiaries in one business segment: the Communications Segment. Inter-company transactions have been eliminated from the consolidated financial statements.
Classification Of Costs And Expenses [Policy Text Block]	Classification of Costs and Expenses Cost of services includes all costs related to delivery of communication services and products. These operating costs include all costs of performing services and providing related products including engineering, network monitoring and transportation costs. Selling, general and administrative expenses include direct and indirect selling expenses, customer service, billing and collections, advertising and all other general and administrative costs associated with our operations.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of our consolidated financial statements in conformity with GAAP requires our management to make estimates and judgements that affect the reported amounts of assets, liabilities, revenue and expenses, and the related disclosure of contingent assets and liabilities. The estimates and judgements used in the accompanying consolidated financial statements are based on our management’s evaluation of the relevant facts and circumstances as of the date of the financial statements. Actual results may differ from those estimates and assumptions.
Revenue [Policy Text Block]	Revenue Recognition See Note 2 – “Revenue Recognition” for a discussion of our revenue recognition policies.
Receivable [Policy Text Block]	Receivables As of December 31, 2021 and 2020, our consolidated receivables totaled $2,426,009 and $1,885,196, net of the allowance for doubtful accounts. We believe our receivables as of December 31, 2021 and 2020 are recorded at their fair value. As there may be exposure or risk with receivables, we routinely monitor our receivables and adjust the allowance for doubtful accounts when events occur that may potentially affect the collection of our receivables.
Allowance For Doubtful Accounts [Policy Text Block]	Allowance for Doubtful Accounts We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. In making the determination of the appropriate allowance for doubtful accounts, we consider specific accounts, historical write-offs, changes in customer relationships, credit worthiness and concentrations of credit risk. Specific accounts receivable are written off once a determination is made that the account is uncollectible. Additional allowances may be required if the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments. The activity in our allowance for doubtful accounts includes the following: Year Ended December 31 2021 2020 Balance at beginning of year $ 160,000 $ 120,000 Additions charged to costs and expenses 155,763 185,251 Accounts written off, net of recoveries (235,763) (145,251) Balance at end of year $ 80,000 $ 160,000
Inventory, Policy [Policy Text Block]	Inventories Inventory includes parts, materials and supplies stored in our warehouses to support basic levels of service and maintenance as well as scheduled capital projects and equipment awaiting configuration for customers. Inventory also includes (i) parts and equipment shipped directly from vendors to customer locations while in transit and (ii) parts and equipment returned from customers that are being returned to vendors for credit. Our inventory value as of December 31, 2021 and 2020 was $5,357,380 and $2,965,960. We value inventory using the lower of cost or net realizable value. Similar to our allowance for doubtful accounts, we make estimates related to the valuation of inventory. As of December 31, 2021 and 2020, we had no inventory reserve. We adjust our inventory carrying value for estimated obsolescence or unmarketable inventory to the net realizable value based upon assumptions about future demand and market conditions. As market and other conditions change, we may establish additional inventory reserves at a time when the facts that give rise to a lower value are warranted. We use the first-in, first-out method of inventory costing for our non-retail inventory. We use the average cost method of inventory costing for our retail inventory.
Property, Plant and Equipment, Policy [Policy Text Block]	Property, Plant and Equipment We record impairment losses on long-lived assets used in operations when events and circumstances indicate the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets. In assessing the recoverability of long-lived assets, we compare the carrying value to the undiscounted future cash flows the assets are expected to generate. If the total of the undiscounted future cash flows is less than the carrying amount of the assets, we would write down those assets based on the excess of the carrying amount over the fair value of the assets. Fair value is generally determined by calculating the discounted future cash flows expected from those assets. Changes in these estimates could have a material adverse effect on the assessment of long-lived assets, thereby requiring a write-down of the assets. Write-downs of long-lived assets are recorded as impairment charges and are a component of operating expenses. We have reviewed our long-lived assets and concluded that no impairment charge on our long-lived assets is necessary. Property, plant and equipment additions are recorded net of any Broadband grants received. We use the group life method (mass asset accounting) to depreciate the assets of our communications companies. Communications plant acquired in a given year is grouped into similar categories and depreciated over the remaining estimated useful life of the group. When an asset is retired, both the asset and the accumulated depreciation associated with that asset are removed from the books. Due to rapid changes in technology, selecting the estimated economic life of communications plant and equipment requires a significant amount of judgment. We periodically review data on expected utilization of new equipment, asset retirement activity and net salvage values to determine adjustments to our depreciation rates. We have not made any significant changes to the lives of these assets in the two year period ended December 31, 2021.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and Intangible Assets We amortize our definite-lived intangible assets over their estimated useful lives. Customer relationships are amortized over fourteen to fifteen years, regulatory rights are amortized over fifteen years and trade names are amortized over three to five years. Intangible assets with finite lives are amortized over their respective estimated useful lives. In accordance with GAAP, goodwill and intangible assets with indefinite useful lives are not amortized, but tested for impairment at least annually. See Note 5 – “Goodwill and Intangibles” for a more detailed discussion of the intangible assets and goodwill. Our goodwill balance was $49,903,029 as of December 31, 2021 and 2020. In the fourth quarter of 2021 and 2020 we completed our annual impairment tests for existing acquired goodwill. This testing resulted in no impairment charges to goodwill at December 31, 2021 and 2020.
Fair Value Measurement, Policy [Policy Text Block]	Financial Derivative Instruments and Fair Value Measurements We have adopted the rules prescribed under GAAP for our financial assets and liabilities. GAAP includes a fair value hierarchy that is intended to increase consistency and comparability in fair value measurements and related disclosures. The fair value hierarchy is based on inputs to valuation techniques used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources, while unobservable inputs reflect a reporting entity’s pricing based upon its own market assumptions. The fair value hierarchy consists of the following three levels: Level 1: Inputs are quoted prices in active markets for identical assets or liabilities. Level 2: Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs that are derived principally from or corroborated by observable market data. Level 3: Inputs are derived from valuation techniques where one or more significant inputs or value drivers are unobservable. We have used financial derivative instruments to manage our overall cash flow exposure to fluctuations in interest rates. We accounted for derivative instruments in accordance with GAAP that requires derivative instruments to be recorded on the balance sheet at fair value. Changes in fair value of derivative instruments must be recognized in earnings unless specific hedge accounting criteria are met, in which case, the gains and losses are included in other comprehensive income rather than in earnings. We have entered into IRSAs with our lender, CoBank to manage our cash flow exposure to fluctuations in interest rates. These instruments are designated as cash flow hedges and are effective at mitigating the risk of fluctuations on interest rates in the marketplace. Any gains or losses related to changes in the fair value of these derivatives are accounted for as a component of accumulated other comprehensive income (loss) for as long as the hedge remains effective. The fair value of our IRSAs is discussed in Note 7 – “Interest Rate Swaps”. The fair value of our swap agreement was determined based on Level 2 inputs.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Other Financial Instruments Other Investments - We conducted an evaluation of our investments in all of our investees in connection with the preparation of our audited financial statements at December 31, 2021. As of December 31, 2021, we believe the carrying value of our investments is not impaired. Debt – We estimate the fair value of our long-term debt based on the discounted future cash flows we expect to pay using current rates of borrowing for similar types of debt. Fair value of the debt approximates carrying value. Other Financial Instruments -
Investments And Other Assets [Policy Text Block]	Investments and Other Assets We are a co-investor with other communication companies in several partnerships and limited liability companies. These joint ventures make it possible to offer services to customers, including digital video services and fiber transport services that we would have difficulty offering on our own. These joint ventures also make it possible to invest in new technologies with a lower level of financial risk. We use the equity method of accounting for these investments that reflects original cost and recognition of our share of the net income or losses from the respective operations. See Note 16 – “Segment Information” for a listing of our investments. Investments in other companies that are not intended for resale and are not accounted for on the equity method of accounting are valued at fair value where there are readily determinable fair values. Investments in other companies that are not intended for resale and are not accounted for on the equity method of accounting are valued at cost where there are no readily determinable fair values. See Note 12 – “Other Investments” for additional information regarding our investments.
Advertising Cost [Policy Text Block]	Advertising Expense Advertising is expensed as incurred. Advertising expense charged to operations was $314,957 and $515,976 in 2021 and 2020.
Interest During Construction [Policy Text Block]	Interest During Construction We include an average cost of debt for the construction of plant in our communications plant accounts.
Income Tax, Policy [Policy Text Block]	Income Taxes We account for income taxes in accordance with GAAP, which requires an asset and liability approach to financial accounting and reporting for income taxes. Accordingly, deferred tax assets and liabilities arise from the difference between the tax basis of an asset or liability and its reported amount in the financial statements and operating and tax credit carryforwards. Deferred tax assets and liabilities are determined using enacted tax rates expected to apply to taxable income in the periods in which those temporary differences are expected to be recovered or settled. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We recognize interest and penalties related to income tax matters as income tax expense. Income tax expense or benefit is the tax payable or refundable, respectively, for the period plus or minus the change in deferred tax assets and liabilities during the period. GAAP requires us to recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more-likely-than-not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. See Note 8 – “Income Taxes” for additional information regarding income taxes.
Collection Of Taxes From Customers [Policy Text Block]	Collection of Taxes from Customers Sales, excise and other taxes are imposed on most of our sales to nonexempt customers. We collect these taxes from our customers and remit the entire amounts to governmental authorities. Our accounting policies dictate that we exclude these taxes collected and remitted from our revenues and expenses.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash investments and receivables. We deposit our cash investments in high credit quality financial institutions accounts which, at times, may exceed federally insured limits. We have not experienced any losses in these accounts and do not believe we are exposed to any significant credit risk. Concentrations of credit risk with respect to trade receivables are limited due to our large number of customers.
Earnings And Dividends Per Share [Policy Text Block]	Earnings and Dividends Per Share Basic and diluted net income per share are calculated as follows: Year Ended December 31, 2021 Year Ended December 31, 2020 Basic Diluted Basic Diluted Net Income $ 12,251,921 $ 12,251,921 $ 9,835,812 $ 9,835,812 Weighted-average common 5,207,759 5,217,722 5,194,006 5,199,696 Net income per share $ 2.35 $ 2.35 $ 1.89 $ 1.89 The weighted-average shares outstanding, basic and diluted, are calculated as follows: Year Ended December 31, 2021 Year Ended December 31, 2020 Basic Diluted Basic Diluted Weighted-average common 5,207,759 5,207,759 5,194,006 5,194,006 Potentially Dilutive RSU's - 9,963 - 5,690 Weighted-average common 5,207,759 5,217,722 5,194,006 5,199,696 Nuvera’s BOD reviews quarterly dividend declarations based on our anticipated earnings, capital requirements and our operating and financial conditions.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Developments In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-04, “Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” ASU 2020-04 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. In January 2021, the FASB issued ASU No. 2101-01, “Reference Rate Reform (Topic 848): Scope.” ASU 2021-01 clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. ASU 2020-04 and ASU 2021-01 are both elective and are effective upon issuance through December 31, 2022. The Company is evaluating the impact this update will have on our consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU 2017-04, “Intangibles – Goodwill and other (Topic 350): Simplifying the Test for Goodwill Impairment.” ASU 2017-04 simplifies the subsequent measurement of goodwill by eliminating the second step of the goodwill impairment test. The second step measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under ASU 2017-04, a company will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. ASU 2017-04 will be applied prospectively and is effective for annual or interim goodwill impairment tests in the fiscal years beginning January 1, 2021. The Company adopted ASU 2017-04 on January 1, 2021, and the adoption of the standard did not have a material effect on our financial position, results of operations or cash flows . In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires entities to use a new forward-looking, expected loss model to estimate credit losses. It also requires additional disclosures relating to the credit quality of trade and other receivables, including information relating to management’s estimate of credit allowances. The Company is required to adopt ASU 2016-13 for fiscal periods beginning after December 15, 2022, including interim periods within that fiscal year. Early adoption as of December 15, 2018, is permitted. Management is evaluating the impact the adoption of ASU 2016-13 will have on the Company’s financial statements (if any). We have reviewed all other significant newly issued accounting pronouncements and determined that they are either not applicable to our business or that no material effect is expected on our financial position and results of operations.
