A lease is a contractual arrangement calling for the lessee (user) to pay the lessor (owner) for use of an asset.
Property, buildings and vehicles are common assets that are leased. Industrial or business equipment is also leased. Since the lessee does not own the asset, it is not responsible for disposing the assets, and therefore, disposal costs are not attributable to the lessee. The lessee usually incurs rentals and operating costs. Finally, a company should treat the lease the same as other contracts, which they must qualify the supplier.

Weighted moving average
Explanation:
The most common subjective forecasting techniques include the following:
- Market surveys
- Employee surveys
- Expert knowledge (Delphi method is a method using expert knowledge)
- Test marketing
Cycle counting is a periodic analysis of inventory in a storage location which is conducted through the counting of samples instead of physically counting the entire inventory available, so as to quickly have an accurate estimate of the inventory available without causing a stop to the day to day working as is the case with physically counting every unit.
The Pareto principle (also known as the 80/20 rule, the law of the vital few, or the principle of fac-tor sparsity) states that, for many events, roughly 80% of the effects come from 20% of the causes.
Weighted moving averages assign a heavier weighting to more current data points since they are more relevant than data points in the distant past. The sum of the weighting should add up to 1 (or 100 percent).

Hiring is often preferred when:
* Frequency of use is low: If equipment is only needed occasionally, hiring is more economical.
* Storage is unavailable: Leased equipment needs storage, which incurs additional costs.
* Lease costs exceed hiring costs for limited use.
Whole-life asset management emphasizes cost-efficient solutions, and hiring equipment for limited use reduces unnecessary expenses compared to leasing or purchasing.

Available inventory (or Inventory position - IP) is equal to inventory on-hand plus quantity on order minus backorder (if any) Reference: CIPS study guide page 117 LO 2, AC 2.3

Decommissioning or disposal should start with the original specifications of the assets so that the organisation and supplier can make an appropriate plan. Some specifications also mention the is-sues regarding to end-of- life environmental factors.
