# Revenue recognition

In accounting, the revenue recognition principle states that revenues are earned and recognized when they are realized or realizable, no matter when cash is received.
It is a cornerstone of accrual accounting together with the matching principle. Together, they determine the accounting period in which revenues and expenses are recognized. In contrast, the cash accounting recognizes revenues when cash is received, no matter when goods or services are sold.
Cash can be received in an earlier or later period than when obligations are met, resulting in the following two types of accounts:
* Accrued revenue: Revenue is recognized before cash is received.
* Deferred revenue: Revenue is recognized when cash is received.

## Rules

Under the revenue recognition principle, when a company received an advance payment, it is not recognized as revenue but as liabilities in the form of deferred income (which requires the company to perform certain obligations), until the following conditions are met:
* The cash or accounts receivables are received, that is, when the advances are readily convertible to cash or receivables.
* When such goods or services are transferred or rendered.
For example: Revenues from selling inventory are recognized at the date of sale, often the date of delivery. Revenues from rendering services are recognized when services are completed and billed. Revenue from permission to use company's assets is recognized as time passes or as assets are used. Revenue from selling an asset other than inventory is recognized at the point of sale, when it takes place.

### Accruals and deferrals

Accrued revenue is an asset that represents income earned by a deliverer when goods or services are delivered, even though payment has not yet been received. When payment is eventually received, the accrued revenue account is adjusted or removed, and the cash account is increased.
Deferred revenue is a liability that represents the future obligation of a deliverer to deliver goods and services, even though the deliverer has already been paid in advance. When the delivery occurs, the deferred revenue account is adjusted or removed, and the income is recognised as revenue.

### International Financial Reporting Standards criteria

The IFRS provides five criteria for identifying the critical event for recognizing revenue on the sale of goods:
* Performance
** Risks and rewards have been transferred from the seller to the buyer.
** The seller has no control over the goods sold.
* Collectability
** Collection of payment is reasonably assured.
* Measurability
** The amount of revenue can be reasonably measured.
** Costs of earning the revenue can be reasonably measured.

### Revenue Recognition under ASC 606 / IFRS 15

In May 2014, the FASB and IASB issued new, converged guidance on revenue recognition. This guidance, known as ASC 606 (or IFRS 15), aims to improve consistency in recognizing revenue from contracts with customers. ASC 606 became effective in 2017 for public companies and 2018 for private companies.
ASC 606 introduces a five-step model for recognizing revenue:
* Identify the contract: A valid contract exists when the parties are committed, the rights and payment terms are clear, and the contract has commercial substance.
* Identify the performance obligations: Determine what goods or services are promised in the contract.
* Determine the transaction price: The amount expected in exchange for the promised goods or services.
* Allocate the transaction price: Split the transaction price based on the standalone selling price of each performance obligation.
* Recognize revenue: Revenue is recognized when control of the goods or services is transferred to the customer.
This model applies to a wide range of industries, ensuring uniformity in how companies report revenue.

## Exceptions
### Revenues not recognized at sale

The rule says that revenue from selling inventory is recognized at the point of sale, but there are several exceptions.
* Buyback agreements: buyback agreement means that a company sells a product and agrees to buy it back after some time. If buyback price covers all costs of the inventory plus related holding costs, the inventory remains on the seller's books. In plain: there was no sale.
* Returns: companies which cannot reasonably estimate the amount of future returns and/or have extremely high rates of returns should recognize revenues only when the right to return expires. Those companies that can estimate the number of future returns and have a relatively small return rate can recognize revenues at the point of sale, but must deduct estimated future returns.

### Revenues recognized before sale
#### Long-term contracts

This exception primarily deals with long-term contracts such as constructions (buildings, stadiums, bridges, highways, etc.), development of aircraft, weapons, and spaceflight systems. Such contracts must allow the builder (seller) to bill the purchaser at various parts of the project (e.g. every 10 miles of road built).
* The percentage-of-completion method says that if the contract clearly specifies the price and payment options with transfer of ownership, the buyer is expected to pay the whole amount and the seller is expected to complete the project, then revenues, costs, and gross profit can be recognized each period based upon the progress of construction (that is, percentage of completion). For example, if during the year, 25% of the building was completed, the builder can recognize 25% of the expected total profit on the contract. This method is preferred. However, expected loss should be recognized fully and immediately due to conservatism constraint. Apart from accounting requirement, there is a need for calculating the percentage of completion for comparing budgets and actuals to control the cost of long-term projects and optimize Material, Man, Machine, Money and time (OPTM4). The method used for determining revenue of a long-term contract can be complex. Usually two methods are employed to calculate the percentage of completion: (i) by calculating the percentage of accumulated cost incurred to the total budgeted cost; (ii) by determining the percentage of deliverable completed as a percentage of total deliverable. The second method is accurate but cumbersome. To achieve this, one needs the help of a software ERP package which integrates Financial, inventory, Human resources and WBS (work breakdown structure) based planning and scheduling while booking of all cost components should be done with reference to one of the WBS elements. There are very few contracting ERP software packages which have the complete integrated module to do this.
* The completed-contract method should be used only if percentage-of-completion is not applicable or the contract involves extremely high risks. Under this method, revenues, costs, and gross profit are recognized only after the project is fully completed. Thus, if a company is working only on one project, its income statement will show $0 revenues and $0 construction-related costs until the final year. However, expected loss should be recognized fully and immediately due to conservatism constraint.

#### Completion of production basis

This method allows recognizing revenues even if no sale was made. This applies to agricultural products and minerals. There is a ready market for these products with reasonably assured prices, the units are interchangeable, and selling and distributing does not involve significant costs.

### Revenues recognized after Sale

Sometimes, the collection of receivables involves a high level of risk. If there is a high degree of uncertainty regarding collectibility then a company must defer the recognition of revenue. There are three methods which deal with this situation:
* Installment sales method allows recognizing income after the sale is made, and proportionately to the product of gross profit percentage and cash collected calculated. The unearned income is deferred and then recognized to income when cash is collected. For example, if a company collected 45% of total product price, it can recognize 45% of total profit on that product.
* Cost recovery method is used when there is an extremely high probability of uncollectable payments. Under this method no profit is recognized until cash collections exceed the seller's cost of the merchandise sold. For example, if a company sold a machine worth $10,000 for $15,000, it can start recording profit only when the buyer pays more than $10,000. In other words, for each dollar collected greater than $10,000 goes towards your anticipated gross profit of $5,000.
* Deposit method is used when the company receives cash before sufficient transfer of ownership occurs. Revenue is not recognized because the risks and rewards of ownership have not transferred to the buyer.
* Generally accepted accounting principles
* Comparison of cash and accrual methods of accounting
* Vendor-specific objective evidence
