Revenue is recognized when obligations under the terms of the contract with our customer are satisfied; generally, this occurs with the transfer of control of our equipment, parts or installation services (typically completed within one day), which occurs at a point in time. Equipment can be redirected during the manufacturing phase such that over time revenue recognition is not appropriate. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Our contracts are non-cancellable and returns are only allowed in limited instances through Crane & Machinery, Inc. Sales, value add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. The expected costs associated with our base warranties continue to be recognized as expense when the products are sold and do not constitute a separate performance obligation.

For instances where equipment and installation services are sold together, the Company accounts for the equipment and installation services separately. The consideration (including any discounts) is allocated between the equipment and installation services based on their stand-alone selling prices. The stand-alone selling prices are determined based on the prices at which the Company separately sells the equipment.

In some instances, the Company fulfills its obligations and bills the customer for the work performed but does not ship the goods until a later date. These arrangements are considered bill-and-hold transactions. In order to recognize revenue on the bill-and-hold transactions, the Company ensures the customer has requested the arrangement, the product is identified separately as belonging to the customer, the product is ready for shipment to the customer in its current form, and the Company does not have the ability to direct the product to a different customer. A portion of the transaction price is not allocated to the custodial services due to the immaterial value assigned to that performance obligation.

Payment terms offered to customers are defined in contracts and purchase orders and do not include a significant financing component. At times, the Company may offer discounts which are considered variable consideration however, the Company applies the constraint guidance when determining the transaction price to be allocated to the performance obligations.

At times, the Company may require an upfront deposit related to its contracts. In instances where an upfront deposit has been received by the Company and the revenue recognition criteria have not yet been met, the Company records a contract liability in the form of a customer deposit, which is classified as a short-term liability on the balance sheet. That customer deposit is revenue that is deferred until the revenue recognition criteria have been met, at which time, the customer deposit is recognized into revenue.

The following table summarizes changes in customer deposits for the year ended December 31, 2019 and 2018:
