5.7 Leases
IFRS 16 and ASC 842 address the accounting for leases, and both require
            lessees to recognize right-of-use assets and lease liabilities on the balance sheet for
            most lease contracts. While the two standards are converged with respect to the need for
            a lessee to recognize a right-of-use asset and a lease liability, differences remain.
            The table below outlines some of the differences between IFRS 16 and ASC 842. Other
            differences may arise as a result of differences between IFRS Accounting Standards and
            U.S. GAAP in other standards, including those related to (1) impairment of financial
            instruments and long-lived assets other than goodwill and (2) the accounting for
            investment properties.
        | Topic | IFRS Accounting Standards (IFRS 16) | U.S. GAAP (ASC 842) | 
|---|---|---|
| Scope  | Scope includes leases of all assets (not limited
                                    to PP&E). Exceptions are similar to those in ASC 842.
                                    Lessees can elect to apply the guidance to rights to use certain
                                    intangible assets. | Scope includes leases of all PP&E and excludes: 
 | 
| Short-term lease definition | A short-term lease is defined as a lease that
                                    has a lease term of 12 months or less and does not include a
                                    purchase option (i.e., the likelihood that the purchase option
                                    will be exercised is not considered). | A short-term lease is defined as a lease that
                                    has a lease term of 12 months or less and does not include a
                                    purchase option that the lessee is reasonably certain to
                                    exercise. | 
| Leases of low-value assets | A lessee may elect to
                                    recognize the payments for a lease of a low-value asset on a
                                    straight-line basis over the lease term (in a manner similar to
                                    its recognition of an operating lease under IAS 17). Such a
                                    lease would not be reflected on the lessee’s balance sheet. IFRS
                                    16 does not define “low value”; however, the Basis for
                                    Conclusions refers to assets individually with a value, when
                                    new, of $5,000 or less.In addition, an entity may adopt a
                                reasonable capitalization policy based on materiality. | There is no exemption for leases of low-value
                                    assets under U.S. GAAP. However, the FASB believes that an
                                    entity may adopt a reasonable capitalization policy based on
                                    materiality.  | 
| Lease classification | Lessee — There is only a single
                                    accounting model for lessees (i.e., all leases are finance
                                    leases).  Lessor — A lessor must perform a lease
                                    classification assessment as of the inception date to determine whether the lease is an
                                    operating or finance lease.  Lessor-Only Considerations  A lease is classified as a finance lease if it transfers
                                    substantially all of the risks and rewards related to ownership;
                                    otherwise, it is classified as an operating lease. This
                                    determination is not based on meeting any criterion. However,
                                    examples of situations that individually or in combination would
                                    indicate a finance lease include: 
 Other situations in which a lease could be a finance lease
                                    include: 
 | Lessee — There are two accounting models
                                    for leases, and the model will dictate the pattern of expense
                                    recognition associated with the lease. Therefore, a lessee must
                                    perform a lease classification assessment on the commencement date. Lessor — A lessor must perform a lease
                                    classification assessment as of the commencement date to
                                    determine whether the lease is an operating, direct financing,
                                    or sales-type lease.  Lessee and Lessor Considerations  Under ASC 842-10-25-2, a lessee must classify a
                                    lease as a finance lease and a lessor must classify a lease as a
                                    sales-type lease if any of the following criteria are met: 
 If none of these criteria are met:

| Lessee’s subsequent accounting for right-of-use
                                    (ROU) asset and lease expense | A single accounting model is used. The ROU asset
                                    is generally amortized on a straight-line basis. This
                                    amortization, when combined with the interest on the lease
                                    liability, results in a front-loaded expense profile. That is,
                                    the single lessee accounting model under IFRS 16 is similar to
                                    that of a finance lease under ASC 842. Interest expense on the
                                    lease liability and amortization of the ROU asset are presented
                                    separately in the income statement.  | The accounting depends on the lease classification: Finance leases — The ROU asset is
                                    generally amortized on a straight-line basis. This amortization,
                                    when combined with the interest on the lease liability, results
                                    in a front-loaded expense profile. Interest and amortization are
                                    presented separately in the income statement. Operating leases — Lease expense generally results in a
                                    straight-line expense profile that is presented as a single line
                                    in the income statement. As interest on the lease liability is
                                    generally declining over the lease term, amortization of the ROU
                                    asset is increasing over the lease term to provide a constant
                                    expense profile. | 
| Lessor accounting | Core model — The core model is based on a
                                    lessor measurement approach for operating and finance
                                    leases. Selling profit for a finance lease is recognized at lease
                                    commencement. Separating lease and nonlease components
                                    — A similar practical expedient is not available. Sales tax and lessor costs — A similar practical expedient
                                    is not available. In addition, there are no similar provisions
                                    related to lessor costs paid directly to a third party by a
                                    lessee. Fair value of the underlying asset — A similar amendment
                                    to the definition of fair value has not been made. | Core model — The core model is based on a
                                    lessor measurement approach for operating, direct financing, and
                                    sales-type leases. Selling profit for a sales-type lease is recognized at lease
                                    commencement. Selling profit on a direct financing lease, if
                                    any, is deferred and recognized as interest income over the
                                    lease term. Separating lease and nonlease components
                                    — ASC 842-10-15-42A offers lessors a practical expedient under
                                    which they can elect not to separate lease and nonlease
                                    components when certain conditions are met. Sales tax and lessor costs — ASC
                                    842-10-15-39A offers lessors a practical expedient under which
                                    they can present sales taxes collected from lessees on a net
                                    basis. In addition, lessor costs paid directly to a third party
                                    by a lessee should be excluded from variable payments. Fair value of the underlying asset — ASC
                                    842-30-55-17A provides specific fair value considerations for
                                    lessors that are not manufacturers or dealers in such a way that
                                    the fair value of the underlying asset is its cost unless a
                                    significant lapse of time has occurred. | 
| Recognition of variable lease payments that do
                                    not depend on an index or rate | A lessee recognizes variable lease payments not
                                    included in its lease liability (e.g., payments based on the
                                    achievement of a target) in the period in which the target is
                                    achieved. | A lessee recognizes variable lease payments not
                                    included in its lease liability (e.g., payments based on the
                                    achievement of a target) in the period in which achievement of
                                    the target that triggers the variable lease payments becomes
                                    probable. | 
| Reassessment of variable lease payments that
                                    depend on an index or rate | A lessee reassesses variable payments based on
                                    an index or rate whenever there is a change in contractual cash
                                    flows (e.g., the lease payments are adjusted for a change in the
                                    CPI) or when the lease obligation is remeasured for other
                                    reasons. | A lessee reassesses variable payments based on
                                    an index or rate only when the lease obligation is remeasured
                                    for other reasons (e.g., a change in lease term or
                                    modification). | 
| Lessee’s incremental borrowing rate | The lessee’s incremental borrowing rate is the
                                    rate a lessee would pay to borrow over a similar term, and with
                                    a similar security, the funds necessary to obtain an asset
                                        with a value similar to the ROU asset in a similar
                                    economic environment. | The lessee’s incremental borrowing rate is the
                                    rate a lessee would pay to borrow, on a collateralized basis
                                    over a similar term, an amount equal to the lease
                                        payments in a similar economic environment. | 
| Discount rate for private companies | No exemptions are provided for private-company lessees. | Private-company lessees may, as an accounting
                                    policy election by asset class, choose to use a risk-free rate
                                    when measuring and classifying a lease. | 
| Modifications of operating leases for
                                    lessors | If an operating lease is modified and not
                                    accounted for as a separate contract, the lessor accounts for
                                    the modified lease as a new lease from the date of the
                                    modification. The lessor should include any prepaid or accrued
                                    lease payments related to the original lease in the lease
                                    payments associated with the new lease. | If an operating lease is modified and not accounted for as a
                                    separate contract, the treatment depends on how the modified
                                    lease is classified: 
 | 
| Modifications that reduce the lease term for
                                    lessees | A reduction in the lease term is considered a
                                    decrease in the scope of the lease. A lessee should thus
                                    remeasure the lease liability, with a proportionate reduction in
                                    the ROU asset, and recognize a gain or loss for any difference
                                    as of the effective date of the modification. | A reduction in the lease term is not
                                    considered a decrease in the scope of the lease. A lessee should
                                    thus remeasure the lease liability, with a corresponding
                                    reduction in the ROU asset, but should not recognize any
                                    gain or loss as of the effective date of the modification unless
                                    the ROU asset is reduced to zero. | 
| Collectibility of lease payments  | There is no explicit guidance on considering the
                                    collectibility of lease payments within IFRS 16.  | A lessor considers the collectibility of lease
                                    payments when determining whether a lease should be classified
                                    as a direct financing lease or an operating lease. A lessor does
                                        not assess the collectibility of lease payments when
                                    determining whether a lease should be classified as a sales-type
                                    lease. As a result of changes in the collectibility of
                                    lease payments, lease income may be recognized on a cash basis.
                                    The collectibility of lease payments for a direct financing or
                                    sales-type lease is assessed under the CECL guidance in ASC
                                    326. | 
| Modifications of sales-type or direct financing
                                    leases for lessors | A lessor’s accounting for a modification to a finance lease (that
                                    is not accounted for as a separate contract) depends on whether
                                    the lease would have been classified as an operating lease had
                                    the modification been in effect at lease inception: 
 | A lessor’s accounting for a modification to a sales-type or
                                    direct financing lease depends on how the original and modified
                                    leases are classified: 
 | 
| Sublease | The intermediate lessor would classify a sublease by considering
                                    the ROU asset of the head lease as the leased asset in
                                    the sublease. | The intermediate lessor would classify a sublease by considering
                                    the underlying asset of the head lease (instead of the
                                    ROU asset) as the leased asset in the sublease. | 
| Sale-and-leaseback arrangements | The transaction would not be considered a sale if it does not
                                    qualify as a sale under IFRS 15. A repurchase option would always result in a failed sale. For transactions that qualify as a sale, the
                                    gain would be limited to the amount related to the residual
                                    portion of the asset sold. The amount of the gain related to the
                                    underlying asset leased back to the lessee would be offset
                                    against the lessee’s ROU asset.  IFRS 16 has been amended to require that a
                                    seller-lessee determine lease payments or “revised lease
                                    payments” such that the seller-lessee does not recognize a gain
                                    or loss related to the right of use it retains.  This amendment
                                    is effective for annual periods beginning on or after January 1,
                                    2024.  | The transaction would not be considered a sale if (1) it does not
                                    qualify as a sale under ASC 606 or (2) the leaseback is a
                                    finance lease. A repurchase option would result in a failed sale unless (1) the
                                    exercise price of the option is at fair value and (2)
                                    alternative assets are readily available in the marketplace. If the transaction qualifies as a sale, the entire gain on the
                                    transaction would be recognized. | 
| Build-to-suit arrangements  | IFRS 16 does not contain guidance for build-to-suit accounting
                                    for lessees during the construction period.  | ASC 842 provides guidance on lessee accounting for build-to-suit
                                    arrangements. The framework focuses on whether a lessee has
                                    “control” of the asset during the construction period. | 
| Balance sheet presentation  | If a lessee does not separately present ROU assets and lease
                                    liabilities on the balance sheet, the lessee must present the
                                    ROU assets as if the underlying asset were owned and disclose
                                    the line item in which its ROU assets and lease liabilities are
                                    included. | If a lessee does not separately present ROU assets and lease
                                    liabilities on the balance sheet, the lessee must disclose the
                                    line item in which its ROU assets and lease liabilities are
                                    included. This requirement applies to both finance leases and
                                    operating leases. | 
| Statement of cash flows | As noted in the “Lessee’s subsequent accounting for ROU asset and lease
                                        expense” key provision above, a lessee is
                                    required to use a single approach (similar to the FASB’s finance
                                    lease approach) to subsequently account for the ROU asset. For
                                    this reason, the lessee should account for payments of interest
                                    as either a financing or an operating activity in the statement
                                    of cash flows, depending on the lessee’s accounting policy
                                    election under IAS 7. | A lessee should present payments associated with operating leases
                                    as an operating activity in the statement of cash flows. A
                                    lessee should present payments associated with finance leases in
                                    the statement of cash flows as (1) a financing activity, for the
                                    principal portion of the payment, and (2) an operating activity,
                                    for the interest portion of the payment. | 
| Related-party leases (leases between entities under common
                                    control) | There is no explicit guidance on the accounting
                                    for related-party leases under IFRS 16 and no specific
                                    consideration of the amortization period of leasehold
                                    improvements in a common-control arrangement under IAS 16. | Before the adoption of ASU 2023-01, entities are
                                    required to determine whether related-party arrangements between
                                    entities under common control contain a lease. If the
                                    arrangement is deemed to be or contain a lease, an entity is
                                    required to classify and account for the lease in a manner
                                    consistent with an arrangement with an unrelated party (i.e.,
                                    “on the basis of the legally enforceable terms and conditions of
                                    the lease”). After the adoption of ASU 2023-01, private
                                    companies and not-for-profit entities that are not conduit bond
                                    obligors can elect, as a practical expedient that can be applied
                                    on an arrangement-by-arrangement basis, to use the written terms
                                    and conditions of a common control arrangement to determine
                                    whether a lease exists and, if so, the classification of and
                                    accounting for that lease. |
