Par Value shares are shares fixed at a set value and do not fluctuate in price.
The value of a par value shares is set by the directors of the company. This value
is usually very low as it also represents the maximum amount of the liability
the shareholders have towards the company. This is an outdated concept but
unfortunately still used today by a few older companies.
As we all know share prices do not remain fixed, so to balance the books
the concept of a share premium is introduced. The share premium is just a book
entry to make up the difference between the par value and the actual value. The
following equation is used to determine the values: Par Value Share + Share
Premium = Actual Share Value.
A non-par value share is the opposite of a Par value share meaning the
share price can fluctuate making a non-par value share the same as the actual
value of the share.
