a) Estimated useful lives or amortization rates used for finite identifiable intangible assets Finite useful life of an asset measures the length of, or number of production or similar units constituting that useful life. The estimated useful life for software which they are amortized corresponds to the periods defined by the contracts or rights from which they originate. Intellectual property rights, patents and other industrial property, service and exploitation rights, mainly relate to water rights and have a finite useful life to the extent to which they are subject to a fixed-term contract or otherwise they are considered to be indefinite. The company owns mining property granted by Corfo, which correspond to assets subject to restitution. For this reason, they are considered assets with a finite useful life and their useful life is assigned until the year 2030 when the contract ends.
| b) | Method used to assess identifiable intangible assets with indefinite useful life
The recoverable value of the cash-generating unit has been determined annually based on a calculation of value-in-use using cash flow projections for a period of 5 years, plus perpetuity on December 31. The current value of future cash flows generated by these assets has been estimated given the variation in sales volumes, market prices and costs, discounted at a weighted average cost of capital (WACC) rate of 8.48% as of December 31, 2019. This group of intangible assets includes water rights acquired in Chile and mining property held by the company in Chile and Australia, which are recorded at acquisition cost.
| c) | Minimum and maximum amortization life or rates of intangible assets:
Estimated useful life or amortization rate |  | Minimum Life or ‎ Rate |  |  | Maximum Life or ‎ Rate |
Mining property, water rights and rights of way |  |  | Indefinite |  |  |  | Indefinite |
Mining property |  |  | 1 year |  |  |  | 11 years |
Intellectual property rights, patents and other industrial property rights, service |  |  | 1 year |  |  |  | 16 years |
Commercial trademarks |  |  | 1 year |  |  |  | 5 years |
IT programs |  |  | 2 years |  |  |  | 6 years |
