The Company disaggregates its revenue from contracts with customers by sales recorded over time and sales recorded at a point in time. The following table presents the Company’s disaggregated revenues (in thousands):

Total revenue	$	507,725	$	419,865	$	884,498	$	720,451

Contract Balances

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (“contract assets”), and deferred revenue (“contract liabilities”) on the condensed consolidated balance sheets. The majority of the Company’s contract amounts are billed as work progresses, in accordance with agreed-upon contractual terms, which generally coincide with the shipment of one or more phases of the project. Billing sometimes occurs subsequent to revenue recognition, resulting in contract assets. The changes in contract assets and the corresponding amounts recorded in revenue relate to fluctuations in the timing and volume of billings.

Contract assets are recorded within accounts receivable, net on the condensed consolidated balance sheets on a contract-by-contract basis and consisted of the following at the end of each reporting period (in thousands):

	June 30, 2023		December 31, 2022
Unbilled receivables	$	141,636	$	101,513

The Company also receives advances or deposits from its customers, before revenue is recognized, resulting in contract liabilities. The changes in contract liabilities relate to advanced orders and payments received by the Company.

Contract liabilities are recorded on a contract-by-contract basis and consisted of the following at the end of each reporting period (in thousands):

	June 30, 2023		December 31, 2022
Deferred revenue	$	114,810	$	178,922

During the six months ended June 30, 2023, the Company converted $160.0 million in deferred revenue to revenue, which represented 89% of the prior year’s deferred revenue balance.

Bill-and-Hold Arrangements

Revenue recognized for the Company’s federal investment tax credit (“ITC”) contracts and standalone system component sales is recorded at a point in time and recognized when obligations under the terms of the contract with the Company’s customer are satisfied. Generally, this occurs with the transfer of control of the asset, which is typically upon delivery to the customer in line with shipping terms.

In certain situations, the Company recognizes revenue under a bill-and-hold arrangement with its customers. An example of such a situation is when customers purchase material prior to the start of construction of a solar project in order to meet the Five Percent Safe Harbor test to qualify for the ITC. Because the customers lack sufficient storage capacity to accept a large amount of material prior to the start of construction, they request that the Company keep the product in its custody. All bill-and-hold inventory is bundled or palletized in the Company’s warehouses, separately identified as not belonging to the Company and ready for immediate transport to the customer project upon request. Additionally, title and risk of loss has passed to the customer and the Company does not have the ability to use the product or direct it to another customer. During the three and six months ended June 30, 2023, the Company recognized $3.5 million and $22.8 million, respectively, in revenue from a single customer for the sale of goods and services that contained bill-and-hold obligations such as storage, handling and other custodial duties.

Remaining Performance Obligations

As of June 30, 2023, the Company had $452.7 million of remaining performance obligations. The Company expects to recognize revenue on 100% of these performance obligations in the next twelve months.
