Significant estimates include estimates used to record purchase price allocation for the Company's acquisitions, fair value measurements used in goodwill impairment tests, impairment estimations of long-lived assets, revenue recognition on cost-to-cost type contracts, allowances for uncollectible accounts, valuations of non-cash capital stock issuances, estimates of the incremental borrowing rate for long-term leases, fair value estimates and the valuation allowance on deferred tax assets.

Revenue from Contract with Customer [Text Block]	4. REVENUE FROM CONTRACTS WITH CUSTOMERS The Electric Power segment provides full service building, maintenance and support to the electrical power distribution, transmission, substation, and emergency response sectors of North America through Front Line Power, Orbital Power Services and Eclipse Foundation. The Telecommunications segment composed of Gibson Technical Services and subsidiaries provides technical implementation, design, maintenance, emergency and repair support services in the broadband, wireless, and outside plant and building technologies. The Renewables segment, Orbital Solar Services, provides engineering, procurement and construction (“EPC”) services that support the development of renewable energy generation focused on utility scale solar and community solar construction. For our construction contracts, revenue is generally recognized over time. Our fixed price and unit-price construction projects generally use a cost-to-cost input method or an output method to measure our progress towards complete satisfaction of the performance obligation as we believe it best depicts the transfer of control to the customer. Revenue is also generally recognized over time as the entity’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Under the output method, progress towards completion is measured based on units of work completed based on the contractual pricing amounts. Under the output method, revenue is determined by actual work achieved. For jobs under the output method, revenue is earned based on each unit in the contract completed. We construct comprehensive revenue calculations based on quantifiable measures of actual units completed multiplied by the agreed upon contract prices per item completed. For our engineering and network design contracts, revenue is also generally recognized over time. In these jobs, timing of revenue recognition also depends on the payment terms of the contract, as our performance does not not not For our service contracts, revenue is also generally recognized over time as the customer simultaneously receives and consumes the benefits of our performance as we perform the service. For our fixed price service contracts with specified service periods, revenue is generally recognized on a straight-line basis over such service period when our inputs are expended evenly, and the customer receives and consumes the benefits of our performance throughout the contract term. For certain of our revenue streams, such as call-out repair and service work, and outage services, that are performed under time and materials contracts, our progress towards complete satisfaction of such performance obligations is measured using an input method as the customer receives and consumes the benefits of our performance completed to date. Due to uncertainties inherent in the estimation process, it is possible that estimates of costs to complete a performance obligation will be revised in the near-term. For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress towards complete satisfaction of the performance obligation, are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. When the current estimate of total costs for a performance obligation indicates a loss, a provision for the entire estimated loss on the unsatisfied performance obligation is made in the period in which the loss becomes evident. Accounts Receivable, Contract Assets and Contract Liabilities Accounts receivable are recognized in the period when our right to consideration is unconditional. We also assess our customer's ability and intention to pay, which is based on a variety of factors, including our historical payment experience with and the financial condition of our customers. Payment terms and conditions vary by contract, and are within industry standards across our business lines. Accounts receivable are recognized net of an allowance for doubtful accounts. The timing of revenue recognition may not Contract liabilities from our construction contracts occur when amounts invoiced to our customers exceed revenues recognized under the cost-to-cost or output method measure of progress. Contract liabilities additionally include advanced payments from our customers on certain contracts and provision for future contract losses for those contracts estimated to close in a gross loss position. Contract liabilities decrease as we recognize revenue from the satisfaction of the related performance obligation and are recorded as either current or long-term, depending upon when we expect to recognize such revenue. Balances and activity in the current contract liabilities as of and for the six June 30, 2022 2021 For the Six Months Ended June 30, (in thousands) 2022 2021 Total contract liabilities - beginning of period $ 6,503 $ 4,873 Other contract additions, net 3,013 776 Revenue recognized (7,149 ) (759 ) Contract settlements — (3,140 ) Total contract liabilities - end of period $ 2,367 $ 1,750 Performance Obligations Remaining Performance Obligations Remaining performance obligations represents the transaction price of contracts with customers for which work has not June 30, 2022, 12 12 June 30, 2022. Any adjustments to net revenues, cost of revenues, and the related impact to operating income are recognized as necessary in the period they become known. These adjustments may may may not one one Performance Obligations Satisfied Over Time To determine the proper revenue recognition method for our contracts, we evaluate whether a single contract should be accounted for as more than one For most of our contracts, the customer contracts with us to provide a significant service of integrating a complex set of tasks and components into a single project or capability (even if that single project results in the delivery of multiple units). Hence, the entire contract is accounted for as one may one one Variable Consideration The nature of our contracts gives rise to several types of variable consideration. In rare instances, we include in our contract estimates, additional revenue for submitted contract modifications or claims against the customer when we believe we have an enforceable right to the modification or claim, the amount can be estimated reliably and its realization is probable. In evaluating these criteria, we consider the contractual/legal basis for the claim, the cause of any additional costs incurred, the reasonableness of those costs and the objective evidence available to support the claim. These amounts are included in our calculation of net revenue recorded for our contracts and the associated remaining performance obligations. Additionally, if the contract has a provision for liquidated damages in the case that the Company misses a timing target, or fails to meet any other contract benchmarks, the Company accounts for those estimated liquidated damages as variable consideration and will adjust revenue accordingly with periodic updates to the estimated variable consideration as the job progresses. Liquidated damages are recognized as variable consideration and are estimated based on the most likely amount that is deemed probable of realization. Significant Judgments Our contracts with certain customers may may At times, customers may not Our contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately rather than together may not In contracts where there are timing differences between when we transfer a promised good or service to the customer and when the customer pays for that good or service, we have determined that, our contracts do not The following tables present the Company's revenues disaggregated by the type of customer: For the Three Months For the Three Months Ended June 30, 2022 Ended June 30, 2021 (in thousands) Electric Power Telecommunications Renewables Total Electric Power Telecommunications Renewables Total Utilities $ 40,454 $ — $ — $ 40,454 $ 4,907 $ — $ — $ 4,907 Telecommunications 472 20,364 — 20,836 — 6,075 — 6,075 Renewables — — 32,280 32,280 — — 537 537 Other 343 — — 343 — — — — Total revenues $ 41,269 $ 20,364 $ 32,280 $ 93,913 $ 4,907 6,075 $ 537 $ 11,519 For the Six Months For the Six Months Ended June 30, 2022 Ended June 30, 2021 (in thousands) Electric Power Telecommunications Renewables Total Electric Power Telecommunications Renewables Total Utilities $ 79,287 $ — $ — $ 79,287 $ 8,097 $ — $ — $ 8,097 Telecommunications 909 36,460 — 37,369 — 6,075 — 6,075 Renewables — — 46,744 46,744 — — 2,908 2,908 Other 767 — — 767 — — — — Total revenues $ 80,963 $ 36,460 $ 46,744 $ 164,167 $ 8,097 $ 6,075 $ 2,908 $ 17,080 The following tables present the Company's revenues disaggregated by type of contract: For the Three Months For the Three Months Ended June 30, 2022 Ended June 30, 2021 (in thousands) Electric Power Telecommunications Renewables Total Electric Power Telecommunications Renewables Total Cost-plus contracts $ 7,373 $ — $ — $ 7,373 $ 1,462 $ — $ — $ 1,462 Fixed price contracts 16,152 2,559 32,280 50,991 760 875 537 2,172 Unit price contracts 17,744 17,805 — 35,549 2,685 5,200 — 7,885 Total revenues $ 41,269 $ 20,364 $ 32,280 $ 93,913 $ 4,907 $ 6,075 $ 537 $ 11,519 For the Six Months For the Six Months Ended June 30, 2022 Ended June 30, 2021 (in thousands) Electric Power Telecommunications Renewables Total Electric Power Telecommunications Renewables Total Cost-plus contracts $ 24,609 $ 112 $ — $ 24,721 $ 2,816 $ — $ — $ 2,816 Fixed price contracts 23,894 4,878 46,744 75,516 1,230 875 2,908 5,013 Unit price contracts 32,460 31,470 — 63,930 4,051 5,200 — 9,251 Total revenues $ 80,963 $ 36,460 $ 46,744 $ 164,167 $ 8,097 $ 6,075 $ 2,908 $ 17,080

The Lenders made a Term Loan to Front Line in the initial principal amount of $105,000,000 for the purposes of financing the acquisition and the associated expenses.

The Credit Agreement provides for mandatory prepayments on the occurrence of events such as sales of assets, Consolidated Excess Cash Flow and Excess Receipts during the term. The credit agreement provides for prepayment premiums (initially 5% on prepayments made in the first 30 months of the term, declining to 1% in the final year of the term). The Term Loan matures on November 17, 2026, subject to acceleration on Events of Default. Interest rate on the term notes is 13.95% at June 30, 2022 with an effective rate of 16.4%.[2]On November 17, 2021, the Company entered into two unsecured promissory notes, one with Kurt A Johnson, Jr, for $34,256,000 and the second for $51,384,000 with Tidal Power Group LLC.
