The Company’s standard revenue transactions are classified in to two 1 Systems - which include all bundled products in which Perma-Pipe designs, engineers, and manufactures pre-insulated piping systems, insulates subsea flowline pipe or subsea oil production equipment. Additionally, this systems classification also includes coating applied to pipes and structures which are provided by the customer. 2 Products - which include cables, leak detection products, heat trace products sold under the PermAlert brand name, material/goods not not The Systems revenue class has generally accounted for approximately 90% 2018 2017 2018 2017 Sales % to Total Sales % to Total Products 13,576 11% 8,495 8% Specialty Piping Systems and Coating Revenue recognized under input method 40,525 31% 39,891 38% Revenue recognized under output method 74,864 58% 56,862 54% Total 128,965 100% 105,248 100% one 1 the customer owns the material that is being insulated or coated, so the customer controls the asset and thus the work-in-process; or 2 the customer controls the work-in-process due to the custom nature of the pre-insulated, fabricated system being manufactured as evidenced by the Company’s right to payment for work performed to date plus seller’s profit margin for products that have no The U.S. operating entities measure revenue by the costs incurred to date relative to the estimated costs to satisfy the contract using the percentage-of-completion method (an input method). Generally, these contracts are considered a single performance obligation satisfied over time and due to the custom nature of the goods and services, the percentage-of-completion method is the most faithful depiction of the Company’s performance as it measures the value of the goods and services transferred to the customer. Costs include all material, labor, and direct costs incurred to satisfy the performance obligations of the contract. Revenue recognition begins when projects costs are incurred. All other operating entities measure revenue by the direct measurement of the outputs produced relative to the remaining goods promised under the contract (output method). Due to the types of end customers, generally these contracts require formal inspection protocols or specific export documentation for units produced or produced and shipped, therefore, the output method is the most faithful depiction of the Company’s performance. Depending on the conditions of the contract, revenue may Contract modifications that occur prior to the start of the manufacturing process will supersede the original contract and revenue is recognized using the modified contract value. Contract modifications that occur during the manufacturing process (changes in scope of work, job performance, material costs, and/or final contract settlements) are recognized in the period in which the revisions are known. Provisions for losses on uncompleted contracts are made in contract liabilities account in the period such losses are identified. Contract assets and liabilities: Contract assets represent revenue recognized in excess of amounts billed (unbilled receivables) for contract work in progress for which the Company has a valid contract and an enforceable right to payment for work completed. Contract liabilities represent billings in excess of costs (unearned revenue) for contract work in progress for which the Company has a valid contract and an enforceable right to payment for work completed. Both customer billings and the satisfaction (or partial satisfaction) of the performance obligation(s) occur throughout the manufacturing process and impacts the period end balances in these accounts.
