Definition of 'Cross Holding'

A situation in which a publicly-traded corporation owns stock in another publicly-traded company. So, technically, listed corporations own securities issued by other listed corporations. Cross holding can lead to double counting, whereby the equity of each company is counted twice when determining value. When double counting occurs, the security's value is counted twice, which can result in estimating the wrong value of the two companies.

only difference between premium fuel and regular fuel is the octane rating.

Octane rating or octane number is a standard measure of the performance of a motor or aviation fuel. The higher the octane number, the more compression the fuel can withstand before detonating. In broad terms, fuels with a higher octane rating are used in high-compression engines that generally have higher performance. In contrast, fuels with low octane numbers are ideal for diesel engines. Use of gasolines with low octane numbers may lead to the problem of engine knockin ..A high compression engine requires higher octane fuel to prevent detonation. Detonation is a condition where the fuel air mixture ignites while being compressed before the spark plug fires. Detonation can cause serious internal damage to an engine. normal petrol gives more mileage in comparison to speed or extra premium petrols as these petrols are for the high cylinder cars that needs pick up and speed acceleration.
