Non-Operating Income
Income from activities outside the core operations. In practice it overlaps other income.
Formula
Interest, dividends, gains on surplus investments, and asset-sale gains. Analysts subtract it when they want a pure operating margin.
What it means
Non-operating income is earned, but it is not the product the customer buys. Valuing it at an operating multiple double-counts a cash pile or a one-time gain.
The clean treatment in a valuation is to value operations on operating profit, and to add surplus cash and non-core investments separately.
How to read it
If non-operating income is a large share of PAT, the P/E is not a multiple of the operating business. Split the earnings before you compare it with a peer that has none.
What to watch
Some "other operating income," such as scrap sales or export incentives, is closer to operations. Do not strip out a recurring operating item just because the word other appears.
