Harrison and Gloria are shareholders of a Canadian-Controlled Private Corporation (CCPC). In the past year, the CCPC received a death benefit of $300,000 from a life insurance policy which had an adjusted cost base (ACB) of $40,000. Also, the corporation sold assets and realized capital gains of $100,000. Assuming the corporation's Capital Dividend Account (CDA) balance was zero at the beginning of the year, what will be the CDA balance at the end of this year?
