A non-core business asset can be any kind of non-essential asset with respect to generating revenue and the core business operations of the company. A non-core asset could be a factory or property that is no longer being used. Non-core assets might also be an entire subsidiary or a holding in another company. Typically, non-core assets can include the following:
Real estate
Commodities
Idle equipment
Natural resources
Investment securities
Land that's not being used
Non-core assets can also be referred to as non-operating assets because they may generate income or provide a return on their investment but are not essential to the ongoing operation of the company.
