15. Leases

Accounting policies

A lease is an agreement that conveys the right to control the use of an identified asset for a defined period of time in return for a payment.

Leases can be embedded within other contracts. If separation is required under IFRS, the embedded lease is recorded separately from its host contract and each component of the contract is accounted and measured in accordance with the applicable regulations.

Leases in which BASF is a lessee mainly relate to real estate, transportation and technical equipment.

As lessee, BASF accounts for all leases, recognizing right-of-use assets for leased assets and liabilities for lease agreements subject to the following principles:

• BASF exercises the exemption for lease agreements with a maximum term of 12 months from the date of provision and low-value assets. Low-value assets are generally defined as leased assets worth a maximum of €5,000.

• Lease liabilities are measured at the present value of the remaining lease payments, taking into account the incremental borrowing rate.

• As a general rule, BASF separates non-lease components, such as services, from lease payments.

• A right-of-use asset is generally recognized at the same amount as the lease liability. Differences may arise from the lease payments made prior to the provision of the leased asset, less any lease incentives received.

• After capitalization, the right-of-use asset is generally depreciated over the lease term using the straight-line method.

• A number of leases, particularly for real estate and barges, include extension and termination options. Extension and termination options are taken into account on recognition of the lease liability only if BASF is reasonably certain that these options will be exercised in the future. When contract terms are being determined, consideration is given to all facts and circumstances that offer an economic incentive for exercising extension options or not exercising termination options. Changes in lease terms arising from the exercise of an extension option or non-exercise of a termination option are only considered if sufficient certainty exists. Estimates and expectations which are asserted at the commencement date of the lease liability and the right-of-use asset and pertain to future payments not yet determined on the date of provision are assessed continuously during the lease term. If subsequently improved or changed knowledge influences the expected payment profile over time, the lease liability is remeasured.

• If an existing lease contract is modified, the lease liability and right-of-use asset must be remeasured, provided the modification changes the payment profile (pursuant to the interest and principal plan) or the scope (either quantitatively or time-related) of use of the asset.
