Financial Statements and Supplementary Data.

The electrical and mechanical construction services industry has experienced growth due principally to the increased content, complexity, and sophistication of electrical and mechanical systems resulting, in part, from growth in digital processing, and cloud computing and data storage.

In addition, facilities of all types require extensive electrical distribution systems, sophisticated power supplies, networks of low-voltage and fiber-optic communications cabling, and various mechanical, plumbing, and fire protection and suppression systems.

Moreover, the need for substantial environmental controls within a building, due to the heightened need to maintain extensive computer systems at optimal temperatures, and the demand for increased energy efficiency, have over the years expanded opportunities for our electrical and mechanical services businesses.

Remaining Unsatisfied Performance Obligations

Our remaining unsatisfied performance obligations (“remaining performance obligations”) at December 31, 2020 were $4.59 billion.

Remaining performance obligations increase with awards of new contracts and decrease as we perform work and recognize revenue on existing contracts.

We include a project within our remaining performance obligations at such time as the project is awarded and agreement on contract terms has been reached.

Our remaining performance obligations include amounts related to contracts for which a fixed price contract value is not assigned when a reasonable estimate of total transaction price can be made.

Remaining performance obligations include unrecognized revenues to be realized from uncompleted construction contracts.

Although many of our construction contracts are subject to cancellation at the election of our customers, in accordance with industry practice, we do not limit the amount of unrecognized revenue included within remaining performance obligations for these contracts as the risk of cancellation is very low due to the inherent substantial economic penalty that our customers would incur upon cancellation or termination.

We believe our reported remaining performance obligations for our construction contracts are firm and contract cancellations have not had a material adverse effect on us.

Remaining performance obligations also include unrecognized revenues expected to be realized over the remaining term of service contracts.

However, to the extent a service contract includes a cancellation clause which allows for the termination of such contract by either party without a substantive penalty, the remaining contract term, and therefore, the amount of unrecognized revenues included within remaining performance obligations, is limited to the notice period required for the termination.

Our remaining performance obligations are comprised of:

(a) original contract amounts, (b) change orders for which we have received written confirmations from our customers, (c) pending change orders for which we expect to receive confirmations in the ordinary course of business, (d) claim amounts that we have made against customers for which we have determined we have a legal basis under existing contractual arrangements and as to which the variable consideration constraint does not apply, and (e) other forms of variable consideration to the extent that such variable consideration has been included within the transaction price of our contracts.

Such claim and other variable consideration amounts were immaterial for all periods presented.

We estimate that approximately 83% of our remaining performance obligations as of December 31, 2020 will be recognized as revenues during 2021.

In furtherance of our EMCOR Values, all EMCOR employees are required to complete diversity & inclusion training, and our current and future leaders undergo implicit association and unconscious bias training.
