PAR â Project Authorization Request An approved PAR is needed before official work is begun on a standard project. It serves as the work authorization by the IEEE-SA Standards Board. NesCom examines PARs and makes recommendations to the IEEE-SA Standards Board regarding their approval. An approved PAR is valid for 4 years. The PAR is referred to when the standard is submitted to RevCom for approval.
In general, par value (also known as par, nominal value or face value) refers to the amount at which a security is issued or can be redeemed. For example, a bond with a par value of $1,000 can be redeemed at maturity for $1,000. This is also important for fixed-income securities such as bonds or preferred shares because interest payments are based on a percentage of par. So, an 8% bond with a par value of $1,000 would pay $80 of interest in a year.
