Disaggregation of Revenues

Revenue is disaggregated by major product category and geography, as we believe these categories best depict how the nature, amount, timing, and uncertainty of our revenue and cash flows are affected by economic factors. The following table includes a reconciliation of the disaggregated revenue by reportable segments. Service revenues are not material and are not separately disclosed.

Contract Balances

Contract balances consist of contract assets and contract liabilities. Contract assets primarily relate to the Company’s rights to consideration for work completed but not yet billed for at the reporting date, or retainage provisions on billings that have been issued. Contract liabilities primarily relate to consideration received from customers prior to transferring goods or services to the customer. Contract assets and contract liabilities are reported in "Accounts receivable, net" and "Other current liabilities" in the Consolidated Balance Sheets, respectively. 

During the three months ended April 30, 2020, the Company’s contract assets decreased by $4,215 while contract liabilities increased by $918, respectively. The change was primarily a result of the contract terms which include timing of customer payments, timing of invoicing, and progress made on open contracts. Due to the short-term nature of the Company’s contracts, substantially all contract liabilities are recognized as revenue during the twelve months thereafter. Changes in our contract assets and liabilities were as follows:

	April 30, 2020		January 31, 2020		$ Change		% Change
Contract assets	$	3,310	$	7,525	$	(4,215)	(56.0)	%
Contract liabilities	$	3,206	$	2,288	$	918	40.1	%

Remaining Performance Obligations

As of April 30, 2020, the Company has no remaining performance obligations related to customer contracts with an original expected duration of one year or more. Revenue recognized from performance obligations satisfied in the prior period during the three-month period ending April 30, 2020, were not material.
