Efficiency = input / output If expenses are $60 and revenue is $80 (perhaps net of interest revenue/expense) the efficiency ratio is 0.75 or 75% (60/80) â meaning that $0.75 are spent for every dollar earned in revenue.
As mentioned above a true antique is more than 100 years old, but some stores value furniture older than 50 years as antique and fine antique dealers will label items antique if they are more than 150 years old. The best way to find out is get the exact age of the piece.
Not all dealers use this 100-year rule. Some will call an antique anything between 80 and 100 years old, and others still use the 1830 guideline. There are also some who, for the sake of simplicity, donât use the term antique at all and refer to everything as either vintage or collectable.
