Final answer:
Credit unions refer to savings and checking accounts as share accounts because they represent ownership in the credit union and highlight the cooperative nature of the organization.
Step-by-step explanation:
When it comes to credit unions, savings and checking accounts are referred to as share accounts because they represent ownership in the credit union. When you open a savings or checking account at a credit union, you are essentially becoming a member and owning a share of the credit union. This is because credit unions are nonprofit financial institutions that are owned and operated by their members. By referring to these accounts as share accounts, credit unions emphasize the cooperative nature of their organization, where members share in the ownership and benefits.
