'''[[International Accounting Standard 17]]''' ('''IAS 17'''), titled '''''Leases''''', was an [[International Accounting Standards]] (IAS) issued by the [[International Accounting Standards Committee]] (IASC) and subsequently maintained by the [[International Accounting Standards Board]] (IASB). The standard prescribed the accounting treatment for lease transactions by classifying leases as either '''finance leases''' or '''operating leases''', depending on the extent to which the risks and rewards incidental to ownership of an asset were transferred from the lessor to the lessee. IAS 17 formed the principal international accounting standard governing lease accounting until it was superseded by [[International Financial Reporting Standard 16]] (IFRS 16), ''Leases'', for annual reporting periods beginning on or after 1 January 2019.

== History ==
IAS 17 was originally issued by the [[International Accounting Standards Committee]] in September 1982 to establish accounting requirements for lease transactions.

The standard was substantially revised in 1997 to improve consistency in lease accounting and to clarify the distinction between finance leases and operating leases.

Following the establishment of the [[International Accounting Standards Board]] in 2001, responsibility for IAS 17 was transferred to the IASB. As concerns grew regarding the extensive use of off-balance-sheet operating leases, the IASB initiated a comprehensive lease accounting project.

In January 2016, the IASB issued [[International Financial Reporting Standard 16]], which replaced IAS 17 for annual reporting periods beginning on or after 1 January 2019.

== Objective ==
The objective of IAS 17 was to prescribe appropriate accounting policies and disclosures for leases by establishing principles for:

* classification of leases;
* recognition of leased assets and liabilities;
* accounting by lessees;
* accounting by lessors;
* disclosure of leasing activities.

The standard sought to ensure that lease transactions were reflected according to their economic substance rather than solely their legal form.

== Scope ==
IAS 17 applied to most lease agreements involving tangible assets.

The standard generally did not apply to:

* lease agreements for mineral rights;
* exploration and extraction of natural resources;
* biological assets;
* licensing agreements covered by other accounting standards.

== Lease classification ==
IAS 17 classified leases into two categories.

=== Finance lease ===
A finance lease was defined as a lease that transferred substantially all the risks and rewards incidental to ownership of an asset to the lessee.

Indicators of a finance lease included:

* transfer of ownership at the end of the lease term;
* bargain purchase options;
* lease terms covering the major part of the asset's economic life;
* present value of lease payments substantially equal to the fair value of the asset.

Finance leases were recognized on the lessee's [[balance sheet]].

=== Operating lease ===
An operating lease was any lease that did not meet the criteria for classification as a finance lease.

Under IAS 17, operating lease payments were generally recognized as an expense on a straight-line basis over the lease term, while the leased asset remained on the lessor's balance sheet.

This treatment allowed many long-term lease obligations to remain off the lessee's balance sheet.

== Lessee accounting ==
For finance leases, lessees recognized:

* a leased asset; and
* a corresponding lease liability.

Lease payments were allocated between:

* reduction of the lease liability; and
* finance charges.

For operating leases, lease payments were generally recognized as operating expenses throughout the lease term.

== Lessor accounting ==
Lessors classified leases as either finance leases or operating leases.

For finance leases:

* the leased asset was derecognized;
* a lease receivable was recognized;
* finance income was recognized over the lease term.

For operating leases:

* the leased asset remained on the lessor's balance sheet;
* lease income was recognized over the lease term.

== Disclosure requirements ==
IAS 17 required disclosures including:

* carrying amount of leased assets;
* future minimum lease payments;
* contingent rents;
* lease terms and conditions;
* lease income for lessors.

These disclosures enabled users to evaluate the effects of leasing activities on financial statements.

== Criticism ==
IAS 17 received significant criticism because:

* many operating leases were excluded from the balance sheet;
* financial leverage could be understated;
* comparability between entities was reduced;
* economically similar transactions sometimes received different accounting treatment.

These concerns ultimately led to the development of IFRS 16.

== Replacement by IFRS 16 ==
IAS 17 was superseded by [[International Financial Reporting Standard 16]], which introduced a single lessee accounting model.

== Impact ==
International Accounting Standard 17 established the principal international framework for lease accounting for more than three decades. Its distinction between finance leases and operating leases significantly influenced corporate financial reporting, although the operating lease model was widely criticized for allowing substantial lease obligations to remain off the balance sheet. The replacement of IAS 17 by IFRS 16 represented one of the most significant changes in modern financial reporting by requiring lessees to recognize most lease obligations on the balance sheet, thereby improving transparency, comparability, and the representation of financial position.
