Final answer:
Doug's FDIC insurance coverage amount depends on the ownership type and the number of banks where he has accounts, with a general FDIC guarantee of up to $250,000 per depositor, per insured bank, for each account ownership category.
Step-by-step explanation:
To determine how much Federal Deposit Insurance Corporation (FDIC) insurance coverage Doug has for his accounts at the bank, we have to understand the FDIC's insurance rules. The FDIC provides deposit insurance which guarantees that depositors will receive up to $250,000 of their money in each deposit ownership category, per insured bank, in the event of a bank failure. If Doug has multiple accounts, the coverage depends on the ownership type (e.g., individual, joint, retirement, etc.) and whether the accounts are at the same bank or different banks.
If Doug has accounts in different ownership categories or at different banks, he could be insured for more than $250,000. However, if all the accounts are in the same ownership category and at the same bank, the insurance limit is $250,000 in total, not per account. Therefore, without additional information regarding the ownership structure or number of banks, it is not possible to provide an exact insurance coverage amount for Doug's accounts.
