| g. | Property: |
Property is measured at cost, including direct acquisition costs, less accumulated depreciation, accumulated impairment losses and any related investment grants and excluding day-to-day servicing expenses.
Depreciation is calculated on a straight-line basis over the useful life of the assets at annual rates as follows:
| % | |||
| Lab equipment | 15 | ||
| Computers | 33 | ||
| Office furniture and equipment | 6 | ||
| Leasehold improvements | see below |
Leasehold improvements are depreciated on a straight-line basis over the shorter of the lease term (including the extension option held by the Company and intended to be exercised) and the expected life of the improvement.
The useful life, depreciation method and residual value of an asset are reviewed at least each year-end and any changes are accounted for prospectively as a change in accounting estimate. Depreciation of an asset ceases at the earlier of the date that the asset is classified as held for sale and the date that the asset is derecognized.
