Revenue Recognition

Our revenues are primarily generated from the manufacturing of custom-engineered products and systems under long-term fixed-price contracts under which we agree to manufacture various products such as traditional and arc-resistant distribution switchgear and control gear, medium-voltage circuit breakers, monitoring and control communications systems, motor control centers, switches and bus duct systems. These products may be sold separately as an engineered solution, but are typically integrated into custom-built enclosures which we also build. These enclosures are referred to as power control room substations (PCRs®), custom-engineered modules or electrical houses (E-Houses). Some contracts may also include the installation and the commissioning of these enclosures.

Revenue from these contracts is generally recognized over time utilizing the cost-to-cost method to measure the extent of progress toward the completion of the performance obligation and the recognition of revenue over time. We believe that this method is the most accurate representation of our performance, because it directly measures the value of the services transferred to the customer over time as we incur costs on our contracts. Contract costs include all direct materials, labor, and indirect costs related to contract performance, which may include indirect labor, supplies, tools, repairs and depreciation costs.

We also have contracts to provide value-added services such as field service inspection, installation, commissioning, modification and repair, as well as retrofit and retrofill components for existing systems. If the service contract terms give us the right to invoice the customer for an amount that corresponds directly with the value of our performance completed to date (i.e., a service contract in which we bill a fixed amount for each hour of service provided), then we recognize revenue over time

in each reporting period corresponding to the amount with which we have the right to invoice. Our performance obligations are satisfied as the work progresses. Revenues from our custom-engineered products and value-added services transferred to customers over time accounted for approximately 92% of total revenues for the three months ended December 31, 2020 and 95% of total revenues for the three months ended December 31, 2019.

We also have sales orders for spare parts and replacement circuit breakers for switchgear that are obsolete or that are no longer produced by the original manufacturer. Revenues from these sales orders are recognized at the time we fulfill our performance obligation to the customer, which is typically upon shipment and represented approximately 8% of total revenues for the three months ended December 31, 2020 and 5% of total revenues for the three months ended December 31, 2019.

Additionally, some contracts may contain a cancellation clause that could limit the amount of revenue we are able to recognize over time. In these instances, revenue and costs associated with these contracts are deferred and recognized at a point in time when the performance obligation is fulfilled.

Selling and administrative costs incurred in relation to obtaining a contract are typically expensed as incurred. We periodically utilize a third-party sales agent to obtain a contract and will pay a commission to that agent. We record the full commission liability to the third-party sales agents at the order date, with a corresponding deferred asset. As the project progresses, we record commission expense based on percentage of completion rates that correlate to the project and reduce the deferred asset. Once we have been paid by the customer, we pay the commission and the liability is reduced.

Performance Obligations

A performance obligation is a promise in a contract or with a customer to transfer a distinct good or service. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue as the performance obligations are satisfied. To determine the proper revenue recognition for contracts, we evaluate whether a contract should be accounted for as more than one performance obligation or, less commonly, whether two or more contracts should be combined and accounted for as one performance obligation. This evaluation of performance obligations requires significant judgment. The majority of our contracts have a single performance obligation where multiple engineered products and services are combined into a single custom-engineered solution. Our contracts generally include a standard assurance warranty that typically ends 18 months after shipment. Occasionally, we provide service-type warranties that will extend the warranty period. These extended warranties qualify as a separate performance obligation, and revenue is deferred and recognized over the warranty period. If we determine during the evaluation of the contract that there are multiple performance obligations, we allocate the transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract.

Remaining unsatisfied performance obligations, which we refer to as backlog, represent the estimated transaction price for goods and services for which we have a material right, but work has not been performed. As of December 31, 2020, we had backlog of $464.9 million, of which approximately $306.8 million is expected to be recognized as revenue within the next twelve months. Backlog may not be indicative of future operating results as orders may be cancelled or modified by our customers. Our backlog does not include service and maintenance-type contracts for which we have the right to invoice as services are performed.

Contract Estimates

Actual revenues and project costs may vary from previous estimates due to changes in a variety of factors. The cost estimation process is based upon the professional knowledge and experience of our engineers, project managers and financial professionals. Factors that are considered in estimating the work to be completed and ultimate contract recovery include the availability and productivity of labor, the nature and complexity of the work to be performed, the availability of materials, and the effect of any delays on our project performance. We periodically review our job performance, job conditions, estimated profitability and final contract settlements, including our estimate of total costs and make revisions to costs and income in the period in which the revisions are probable and reasonably estimable. Whenever revisions of estimated contract costs and contract values indicate that the contract costs will exceed estimated revenues, thus creating a loss, a provision for the total estimated loss is recorded in that period.

For the three months ended December 31, 2020 and 2019, our operating results were positively impacted by $5.5 million and $4.3 million, respectively, as a result of changes in contract estimates related to projects in progress at the beginning of the respective period. These changes in estimates resulted primarily from favorable project execution and negotiations of variable consideration, discussed below, as well as revenue and reduced costs recognized from project cancellations and other changes in facts and circumstances during these periods.

Variable Consideration

It is common for our long-term contracts to contain variable consideration that can either increase or decrease the transaction price. Due to the nature of our contracts, estimating total cost and revenue can be complex and subject to variability due to change orders, back charges, spare parts, early completion bonuses, customer allowances and liquidated damages. We estimate the amount of variable consideration based on the expected value method, which is the sum of probability-weighted amount, or the most likely amount method which uses various factors including experience with similar transactions and assessment of our anticipated performance. Variable consideration is included in the transaction price if legally enforceable and to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur once the uncertainty associated with the variable consideration is resolved.

Contract Modifications

Contracts may be modified for changes in contract specifications and requirements. We consider contract modifications to exist when the modification either creates new or changes the enforceable rights and obligations under the contract. Most of our contract modifications are for goods and services that are not distinct from the existing performance obligation. Contract modifications result in a cumulative catch-up adjustment to revenue based on our measure of progress for the performance obligation.

Contract Balances

The timing of revenue recognition, billings and cash collections affects accounts receivable, contract assets and contract liabilities in our Condensed Consolidated Balance Sheets.

Contract assets are recorded when revenues are recognized in excess of amounts billed for fixed-price contracts as determined by the billing milestone schedule. Contract assets are transferred to accounts receivable when billing milestones have been met, or we have an unconditional right to payment.

Contract liabilities typically represent advance payments from contractual billing milestones and billings in excess of revenue recognized. It is unusual to have advanced milestone payments with a term greater than one year, which could represent a financing component on the contract.

Our contract assets and liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period and are generally classified as current. The timing of contract billing milestones related to our Fiscal 2020 contract award for a large industrial project contributed significantly to our net contract liability at September 30, 2020 and December 31, 2020.

Contract assets and liabilities as of December 31, 2020 and September 30, 2020 are summarized below (in thousands):

	December 31, 2020		September 30, 2020
Contract assets	$	47,886	$	50,995
Contract liabilities	(70,939)		(79,445)
Net contract liability	$	(23,053)	$	(28,450)

The decrease in net contract liability at December 31, 2020 from September 30, 2020 was primarily due to the timing of contract billing milestones and new orders. To determine the amount of revenue recognized during the period from contract liabilities, we first allocate revenue to the individual contract liability balance outstanding at the beginning of the period until the revenue exceeds that balance. During the three months ended December 31, 2020, we recognized revenue of approximately $36.4 million that was related to contract liabilities outstanding at September 30, 2020.

The timing of our invoice process is typically dependent on the completion of certain milestones and contract terms and subject to agreement by our customer. Payment is typically expected within 30 days of invoice. Any uncollected invoiced amounts for our performance obligations recognized over time, including contract retentions, are recorded as accounts receivable in the Condensed Consolidated Balance Sheets. Certain contracts contain retention provisions that become due upon completion of contractual requirements. As of December 31, 2020 and September 30, 2020, accounts receivable included retention amounts of $7.8 million and $6.9 million, respectively. Of the retained amount at December 31, 2020, $6.1 million is expected to be collected in the next twelve months and is recorded in accounts receivable. The remaining $1.7 million is recorded in other assets.
