Grandfathering

Grandfathering, often enacted through a grandfather clause, is a provision that allows pre-existing entities, conditions, or practices to be exempt from a new rule, regulation, or requirement. This means that while all new cases are subject to the new standards, those that existed before the change can continue to operate under the old rules.

In business and finance, grandfathering is frequently used in pricing models, contracts, and regulatory compliance. For example, a SaaS company may increase its subscription prices for new customers but allow its existing customer base to continue on their original, lower-priced plans. This practice can impact revenue recognition and long-term forecasts by creating multiple pricing cohorts within the customer base.

The principle is also applied to employee benefits, where existing employees might retain a pension plan that is no longer offered to new hires, affecting compensation planning and future operating expenses (OPEX). The primary goal is to avoid disrupting established agreements and expectations, which could otherwise lead to customer churn or employee dissatisfaction.
