NOTE 2        -        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.)

F.
Property and Equipment
 
The Company accounts for property and equipment in accordance with Accounting Standards Codification (“ASC”) 360Accounting for the Property, Plant, and Equipment (“ASC 360”). Property and equipment are presented at cost, including capitalizable costs. Capitalizable costs include only costs that are identifiable with, and related to, the property and equipment and are incurred prior to their initial operation. Identifiable incremental direct costs include costs associated with constructing, establishing and installing property and equipment, and costs which are directly related to pre-production test runs of property and equipment that are necessary for preparing such property and equipment for their intended use. Maintenance and repairs are charged to expenses as they are incurred.

Property and equipment are presented net of investment grants received, and less accumulated depreciation .
 
Depreciation is calculated based on the straight-line method over the Company’s estimated useful lives of the assets or terms of the related leases, as follows:

Buildings and building improvements, including facility infrastructure
10-25 years
Machinery and equipment, software and hardware
3-15 years

In connection with the periodic review of the estimated useful lives of property and equipment at the Company’s foundry manufacturing facilities, the Company determined during 2015, that the estimated useful lives of machinery and equipment should be extended to 15 years from 7 years and the estimated useful lives of facility infrastructure should be extended to 25 years from 14 years. The Company extended the estimated useful lives of these assets as a result of the extended use of mature technologies, longer processes and product life cycles, the versatility of manufacturing equipment, facility systems and infrastructure to provide better flexibility to meet changes in customer demand and the ability to re-use equipment over several technology cycles significantly extending the estimated usage period of such assets. For further details, see Note 8A. Impairment charges, if needed, are determined based on the policy outlined in R below.
