In the context of managing inventory:

1. I guess that 'costs of capital' is the fixed asset or equipment to manage the inventory, major costs will include
- the warehouse (purchase cost, decoration cost)
- the shelves for the stock,
- the forklifts to handle the stock.

2. Example of costs associated with stock-outs
- packaging amterial costs
- packaging staff costs
- delivery costs
- driver, delivery staff, oil, depreciation for delivery trucks owned by the company to delivery the stock

1. you mean cost of share capital or not?
2. stock out cost: transportation, delivery man......
