A basis processing rule, or entity basis processing rule, allows you to apply a set of income characteristics defined using a security processing rule to one or more securities for a specific portfolio/accounting basis. For example, you can create a security processing rule to make a redeemable preferred stock eligible for amortization only when processed for a specific portfolio. During processing, the system uses the income characteristics defined at the basis processing rule level to override any corresponding income characteristics defined at the security level.
A A basis processing rule for a given security supersedes any security processing rule assigned directly to that security. You can change the basis processing rule to allow for historical changes. For example, if the security is eligible for amortization but you need to disable amortization for a period of time, you must accomplish this using the amortization/accretion rule rather than the basis processing rule.
