3. REVENUE

The following table summarizes the percentages of our net sales attributable to each of our vertical markets for the three months ended March 31, 2021 and 2020:

	Three Months Ended March 31,
	2021		2020
Construction	58.5	%	57.8	%
CIG	25.7		26.6
Industrial & Utility	15.8		15.6
Total net sales	100.0	%	100.0	%

Certain reclassifications have been made to the vertical market assigned to customers in the prior year’s information to conform to the March 31, 2021 presentation.

We had no material contract assets, contract liabilities, or deferred contract costs recorded on the condensed consolidated balance sheet as of March 31, 2021 and December 31, 2020. In addition, for the three months ended March 31, 2021 and 2020, revenue recognized in the reporting period that was included in the contract liability balance at the beginning of the period is not material.

Revenue expected to be recognized in any future year related to remaining performance obligations is not material. As permitted in ASC Topic 606, “Revenue from Contracts with Customers”, we have elected to omit disclosure related to performance obligations for revenue pertaining to contracts that have an original expected duration of one year or less, to contracts where revenue is recognized as invoiced and to contracts with variable consideration related to wholly unsatisfied performance obligations.
