If the goodwill-to-asset ratio increases, it can mean that the company is recording a proportionately higher amount of goodwill, assuming total assets are remaining constant. It is generally good to see a company increasing its assets regularly; however, if these increases are coming from intangible assets, such as goodwill, the increases may not be as good.

Increases in the goodwill-to-asset ratio might suggest that a company has been aggressively acquiring other firms or has seen its tangible assets decrease in value. When a large portion of total assets are attributable to intangible assets (such as goodwill), the company may be at risk of having that portion of its asset base wiped out quickly if it must record any goodwill impairments. Decreases in the goodwill-to-assets ratio suggest that the company has either written down some goodwill or increased its tangible assets.

Asset needs vary from industry to industry. This is why comparing goodwill-to-assets ratios is generally most meaningful among companies within the same industry. By comparing a company's goodwill to assets ratio to those of other companies within the same industry, investors can get a feel for how a company is managing its goodwill.
