Revenue Recognition

The Company recognizes sales of products and services based on the five-step analysis of transactions as provided in Topic 606. For all contracts with customers, the Company first identifies the contract which usually is established when the customer’s purchase order is accepted or acknowledged. Next the Company identifies the performance obligations in the contract. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. The Company then determines the transaction price in the arrangement and allocates the transaction price to each performance obligation identified in the contract. The Company’s allocation of the transaction price to the performance obligations are based on the relative standalone selling prices for the goods and services contained in a particular performance obligation. The transaction price is adjusted for the Company’s estimate of variable consideration which may include discounts if the Company would fail to meet certain performance requirements, volume discounts or early payment discounts. To estimate variable consideration, the Company utilizes historical experience and known terms. Variable consideration in contracts for the years ended September 30, 2020 and 2019 was insignificant.

For sales of aftermarket parts or products with a low level of customization and engineering time, the Company recognizes revenues at the time risks and rewards of ownership pass, which is generally when products are shipped or delivered to the customer as the Company has no obligation for installation. The Company considers shipping and handling services to be fulfillment activities and as such they do not represent separate performance obligations for revenue recognition. Sales of service arrangements are recognized as the services are performed.

For certain arrangements where there is significant customization to the product and for long-term construction-type sales contracts, revenue may be recognized over time. In these instances, revenue is recognized using a measure of progress that applies an input method based on costs incurred in relation to total estimated costs. These arrangements include large capital water treatment projects, systems and solutions for municipal and industrial applications. The nature of the contracts is generally fixed price with milestone billings. In order for revenue to be recognized over a period of time, the product must have no alternative use and the Company must have an enforceable right to payment for the performance completed to date, including a normal profit margin, in the event of termination for convenience. If these two criteria are not met, revenues from these contracts will not be recognized until construction is complete. Contract revenues and cost estimates are reviewed and revised quarterly at a minimum and the cumulative effect of such adjustments are recognized in current operations. The amount of such adjustments have not been material.

The Company has made accounting policy elections to exclude all taxes by governmental authorities from the measurement of the transaction price and that long-term construction-type sales contracts, or those contracts for products with significant customization that the total contract price is less than $100 will be recorded at the point in time when the construction is complete.

Performance Obligations

The Company elects to apply the practical expedient to exclude from this disclosure revenue related to performance obligations if the product has an alternative use and the Company does not have an enforceable right to payment for the performance completed to date, including a normal profit margin, in the event of termination for convenience. The Company maintains a backlog of confirmed orders of approximately $165,563 at September 30, 2020. This backlog represents the aggregate amount of the transaction price allocated to performance obligations that were unsatisfied or partially unsatisfied as of the end of the reporting period. The Company estimates that the majority of these performance obligations will be satisfied within the next twelve months.

The recording of assets recognized from the costs to obtain and fulfill customer contracts primarily relate to the deferral of sales commissions. The Company’s costs incurred to obtain or fulfill a contract with a customer are classified as non-current assets and amortized to expense over the period of benefit of the related revenue. These costs are recorded within Cost of product sales and services. The amount of contract costs was insignificant at September 30, 2020.

The Company offers standard warranties that generally do not represent a separate performance obligation. In certain instances, a warranty is obtained separately from the original equipment sale or the warranty provides incremental services and as such is treated as a separate performance obligation.

Disaggregation of Revenue

In accordance with Topic 606, the Company disaggregates revenue from contracts with customers into source of revenue, reportable operating segment and geographical regions. The Company determined that disaggregating revenue into these categories meets the disclosure objective in Topic 606 which is to depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors.
