Revenue from Contract with Customer [Text Block]	4. REVENUE FROM CONTRACTS WITH CUSTOMERS The Electric Power and Solar Infrastructure Services segment provides full service building, maintenance and support to the electrical power distribution, transmission, substation, renewables, and emergency response sectors of North America through Orbital Power Services and Eclipse Foundation Group. 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, and Gibson Technical Services provides technical implementation, maintenance, emergency and repair support services in the broadband, wireless, and outside plant and building technologies. The Integrated Energy Infrastructure Solutions and Services segment subsidiaries, collectively referred to as Orbital Gas Systems, generate their revenue from a portfolio of products, services and resources that offer a diverse range of personalized gas engineering solutions to the gas utilities, power generation, petrochemical, emissions, manufacturing and automotive industries among others. Orbital Gas Systems accounts for a majority of its contract revenue proportionately over time. For our performance obligations satisfied over time, we recognize revenue by measuring the progress toward complete satisfaction of that performance obligation. The selection of the method to measure progress towards completion can be either an input method or an output method and requires judgment based on the nature of the goods or services to be provided. For our construction contracts, revenue is generally recognized over time. Our 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 these methods best depict the transfer of control to the customer. 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 or hours of work completed. The timing of revenue recognition for Integrated Energy Infrastructure products 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. 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. Under the output method, revenue is determined by actual work achieved. For time and materials jobs, revenue is recognized based on the output of hours of work completed multiplied by the contractual agreed upon rate per hour. For the remainder of 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. Revenue is also generally recognized over time as the customer simultaneously receives and consumes the benefits of our performance as we perform the service. Product-type contracts (for example, sale of GasPT units) for which revenue does not not 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, although our standard terms include a requirement of payment within 30 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.

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 Performance Obligations Satisfied at a Point in Time Revenue from goods and services transferred to customers at a single point in time accounted for 13% and 20% of revenues for the three June 30, 2021 2020, six June 30, 2021 2020, 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, we account 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 only when we estimate that they will be a factor in the performance of the contract and are not 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.

Note payable with an original balance for $1.4 million to First Insurance Funding was executed in July 2020 by the Company for the purposes of financing a portion of the Company's insurance coverage. The Note had an annual percentage rate of 3.35% with nine monthly payments of approximately $159 thousand and was paid off in the three months ended June 30 ,2021. The Company financed two additional insurance policies in the fourth quarter of 2020 for $0.1 million and $0.4 million, respectively. The smaller of which matured in April 2021 and the other of which will mature in September 2021, and for which had annual interest rates of 3.35% and 4.35%, respectively.

[2]

On April 30, 2020 and May 2, 2020, the Company entered into unsecured loans in the aggregate principal amount of approximately $1.9 million (the “Loans”) pursuant to the Paycheck Protection Program (the “PPP”), sponsored by the Small Business Administration (the “SBA”) as guarantor of loans under the PPP. The Loans, and interest accrued thereon, is forgivable, partially or in full, if certain conditions are met. The Loans are evidenced by four promissory notes, three with Bank of America, NA which are dated as of April 30, 2020 and one with Dogwood State Bank dated May 2, 2020. The Bank of America notes were to mature two years from funding date of the notes and the Dogwood State Bank note was to mature two years from the note date. Each of the notes bore interest at a fixed rate of 1.0% per annum with payments deferred. Prepayments on the Loans were permitted at any time prior to maturity with no prepayment penalties. All $1.9 million of the loans outstanding at December 31, 2020 were forgiven in the three months ending June 30, 2021. The remaining $1.4 million of Pay-check Protection loans were acquired as part of the GTS acquisition. The Company has a contingent receivable associated with the remaining PPP loan whereby the Company would be paid by the Sellers of GTS if the remaining PPP loan was not forgiven.

[3]

Includes vehicle and equipment loans with interest rates ranging from 5.74% to 8.99%.

[4]

To refinance an earlier non-recourse note and to provide the Company with additional capital, the Company took out two non-recourse agreements with C6 Capital for the sale of future revenues in the total amount of $3.5 million. These agreements had no stated interest rate and the original issue discount including upfront fees amortized using an effective interest rate of approximately 117%. After combined weekly payments of approximately $54 thousand for the first four weeks, the combined payments increased to approximately $116 thousand until June 2021. As of June 30, 2021, the non-recourse note has been paid off.

[5]

On November 13, 2020, the Company completed a Securities Purchase Agreement with an institutional investor, pursuant to which the Company agreed to issue to the Investor an unsecured convertible instrument in the principal amount of $2.2 million (the “Convertible Security” or “Note”) to purchase shares of the Company’s common stock, $0.001 par value per share (the “Common Stock”) against the payment of the applicable consideration therefore. Upon the closing on November 13, 2020, the Company received gross proceeds of $2.2 million before fees and other expenses associated with the transaction, including but not limited to, a $0.2 million original issue discount payable to the Investor. The net proceeds received by the Company was used primarily for working capital, debt repayment and general corporate purposes. The Note is payable in full within eighteen (18) months after the purchase price date in accordance with the terms set forth in the Note and accrues interest on the outstanding balance at the rate of ten percent (10%) per annum from the Purchase Price Date until the Note is paid in full. All interest shall compound daily and shall be payable in accordance with the terms of the Note. Company has the right to prepay all or any portion of the outstanding balance in an amount equal to 115% multiplied by the portion of the outstanding balance to be prepaid. The creditor may request payment of up to $250 thousand per month beginning 6 months after initial issuance. Original issue discount is amortized over the expected life of the investment at an effective interest rate of approximately 29%. The Company elected the fair value option for this note and as a result did not bifurcate any potential embedded derivatives. In February 2021, the Company negotiated modified terms which effectively removed the convertible option from the note and the Company recorded a $250 thousand loss on extinguishment and its carrying value was $2.4 million at June 30, 2021. See Note 12 for more information on the fair value of this note payable. On March 23, 2021, the Company completed a second note payable with the same institutional investor with a face amount of $10.7 million, a stated interest rate of 9.0%, an estimated effective interest rate of 19.6%, an original issue discount of $1.0 million and a carrying value of $10.2 million at June 30, 2021. The note payable is payable within eighteen (18) months after the purchase date and the creditor may request payment of up to $1 million per month beginning 6 months after initial issuance. On May 11, 2021, the Company completed a third note purchase agreement with the institutional investor with a face amount of $10.7 million, a stated interest of 9% per annum and a combined original issue discount and unamortized prepaid fees of $1.0 million and a carrying value of $10.0 million at June 30, 2021. The net proceeds were to be used for working capital, future acquisitions and general corporate purposes. Beginning six (6) months from the purchase price date, Investor has the right, in its sole and absolute discretion, to redeem all or any portion of the Note (such amount, the “Redemption Amount”) subject to the maximum monthly redemption amount of $1,000,000 per calendar month, by providing Company with a “Redemption Notice," and is payable in full within 18 months of issuance.
