Customer Deposits

As of March 31, 2024 and December 31, 2023, Corning had customer deposits of approximately $1.1 billion and $1.2 billion, respectively.  Most of these customer deposits were non-refundable and allowed customers to secure rights to products produced by Corning under long-term supply agreements, generally over a period of up to ten years.  As products are delivered to customers, Corning will recognize revenue and reduce the amount of the customer deposit liability.

For the three months ended  March 31, 2024 and 2023, customer deposits recognized were $80 million and $70 million, respectively.

Deferred Revenue

As of March 31, 2024 and December 31, 2023, Corning had deferred revenue of approximately $826 million and $860 million, respectively.  Deferred revenue was primarily related to the performance obligations of non-refundable consideration previously received by HSG from its customers under long-term supply agreements.  

Deferred revenue is tracked on a per-customer contract-unit basis. As customers take delivery of the committed volumes under the terms of the contract, a per-unit amount of deferred revenue is recognized when control of the promised goods is transferred to the customer based upon the units delivered compared to the remaining contractual units.  For the three months ended  March 31, 2024 and 2023, the amount of deferred revenue recognized in the consolidated statements of income was not material.
