We identify each of the material performance obligations in these arrangements and allocate the total transaction price to each performance obligation based on its relative selling price. In most cases, the individual performance obligations are also sold separately and we use that price as the basis for allocating revenue to the included performance obligations. When an arrangement includes multiple performance obligations and invoicing to the customer does not match the allocated portion of the transaction price, unbilled revenue or deferred revenue is recorded reflecting that difference. Unbilled and deferred revenue are discussed in more detail below.</span>

Our long-term arrangements generally do not include committed volumes until underlying purchase orders are issued. Our performance obligations vary by contract, but may include diesel and natural gas engines and engine-related component products, including filtration, aftertreatment, turbochargers, fuel systems, controls systems, air handling systems, transmissions, power generation systems and construction related projects, batteries, electrified power systems, hydrogen systems, fuel cells, parts, maintenance services and extended warranty coverage.</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Typically, we recognize revenue on the products we sell at a point in time, generally in accordance with shipping terms, which reflects the transfer of control to the customer. Since control of construction projects transfer to the customer as the work is performed, revenue on these projects is recognized based on the percentage of inputs incurred to date compared to the total expected cost of inputs, which is reflective of the value transferred to the customer. Revenue is recognized under long-term maintenance and other service agreements over the term of the agreement as underlying services are performed based on the percentage of the cost of services provided to date compared to the total expected cost of services to be provided under the contract. Sales of extended coverage are recognized based on the pattern of expected costs over the extended coverage period or, if such a pattern is unknown, on a straight-line basis over the coverage period as the customer is considered to benefit from our stand ready obligation over the coverage period. In all cases, we believe cost incurred is the most representative depiction of the extent of service performed to date on a particular contract.</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Our arrangements may include the act of shipping products to our customers after the performance obligation related to that product has been satisfied. We have elected to account for shipping and handling as activities to fulfill the promise to transfer goods and have not allocated revenue to the shipping activity. All related shipping and handling costs are accrued at the time the related performance obligation has been satisfied.</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Our sales arrangements may include the collection of sales and other similar taxes that are then remitted to the related taxing authority.

These programs are designed to promote the sale of our products in the channel or encourage the usage of our products by OEM customers. When there is uncertainty surrounding these sales incentives, we may limit the amount of revenue we recognize under a contract until the uncertainty has been resolved. Sales incentives primarily fall into three categories:</span><span style="font-family:inherit;font-size:10pt;"> </span></div><table cellpadding="0" cellspacing="0" style="padding-bottom:10px;font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"/><td/></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:24px;"><span style="font-family:inherit;font-size:10pt;">•</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Volume rebates;</span></div></td></tr></table><table cellpadding="0" cellspacing="0" style="padding-bottom:10px;font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"/><td/></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:24px;"><span style="font-family:inherit;font-size:10pt;">•</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Market share rebates; and</span></div></td></tr></table><table cellpadding="0" cellspacing="0" style="padding-bottom:10px;font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"/><td/></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:24px;"><span style="font-family:inherit;font-size:10pt;">•</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Aftermarket rebates.</span></div></td></tr></table><span style="font-family:inherit;font-size:10pt;">For volume rebates, we provide certain customers with rebate opportunities for attaining specified volumes during a particular quarter or year. We consider the expected amount of these rebates at the time of the original sale as we determine the overall transaction price. We update our assessment of the amount of rebates that will be earned quarterly based on our best estimate of the volume levels the customer will reach during the measurement period. For market share rebates, we provide certain customers with rebate opportunities based on the percentage of their production that utilizes our product. These rebates are typically measured either quarterly or annually and we assess them at least quarterly to determine our current estimates of amounts expected to be earned. These estimates are considered in the determination of transaction price at the time of the original sale based on the current market shares, with adjustments made as the level changes. For aftermarket rebates, we provide incentives to promote sales to certain dealers and end-markets. These rebates are typically paid on a quarterly, or more frequent basis. At the time of the sales, we consider the expected amount of these rebates when determining the overall transaction price. Estimates are adjusted at the end of each quarter based on the amounts yet to be paid. These estimates are based on historical experience with the particular program.</span>

Rights of return do not exist for the majority of our sales other than for quality issues. We do offer certain return rights in our aftermarket business, where some aftermarket customers are permitted to return small amounts of parts and filters each year, and in our power generation business, which sells portable generators to retail customers.

We are generally compensated under such arrangements on a cost per hour of usage basis. We typically can estimate the expected usage over the life of the contract, but reassess the transaction price each quarter and adjust our recognized revenue accordingly. Certain maintenance agreements apply to generators used to provide standby power, which have limited expectations of usage. These agreements may include monthly minimum payments, providing some certainty to the total transaction price. For these particular contracts that relate to standby power, we limit revenue recognized to date to an amount representing the total minimums earned to date under the contract plus any cumulative billings earned in excess of the minimums. We reassess the estimates of progress and transaction price on a quarterly basis. For prime power arrangements, revenue is not subject to such a constraint and is generally equal to the current estimate on a percentage of completion basis times the total expected revenue under the contract.</span><span style="font-family:inherit;font-size:10pt;"> </span></div>

We record deferred revenue when we are entitled to bill a customer in advance of when we are permitted to recognize revenue. Deferred revenue may arise in construction contracts, where billings may occur in advance of performance or in accordance with specific milestones. Deferred revenue may also occur in long-term maintenance contracts, where billings are often based on usage of the underlying equipment, which generally follows a predictable pattern that often will result in the accumulation of collections in advance of our performance of the related maintenance services.
