Another fundamental financial and business performance measure. This term means different things to different people (often depending on perspective and what is actually being judged) so it's important to clarify understanding if interpretation has serious implications. Many business managers and owners use the term in a general sense as a means of assessing the merit of an investment or business decision. 'Return' generally means profit before tax, but clarify this with the person using the term - profit depends on various circumstances, not least the accounting conventions used in the business.
