As Taleb explains in his book, antifragility is fundamentally different from the concepts of resiliency (i.e. the ability to recover from failure) and robustness (that is, the ability to resist failure).
The noun UNEARNED INCOME has 2 senses: 1. personal income that you did not earn (e.g., dividends or interest or rent income). 2. (accounting) income received but not yet earned (usually considered a current liability on a company's balance sheet). Familiarity information: UNEARNED INCOME used as a noun is rare.
An unearned fee in accounting is money a business collects from a customer up front for services the company has yet to perform, such as a prepaid annual membership. If your small business collects unearned fees, you must record the fees initially as a liability on the balance sheet.
