30c: depreciating assets that outlive their expected lifespan?

CFA Level I FRA
#1

You are a restaurant and you have paid $11,000 for a coffeemaker. You estimate that the machine will either last 5 years or make 10,000 cups of coffee. Salvage value is 1,000

What happens if you use the machine for 6 years and/or it produces 20,000 cups of coffee before breaking down? How is that reflected in the financial statements (especially with depreciation)?

#2

After you reach salvage value, you stop depreciating the asset, no matter how long it lasts.
