Which of the following statements regarding mutual fund shares is FALSE?

The correct answer highlights a misunderstanding regarding the incorporation of the double category method for determining the basis of mutual fund shares. The basis of mutual fund shares is typically calculated using the cost basis, which reflects the original purchase price plus any additional costs associated with acquiring the shares. Cost basis methods, including specific share identification and first-in, first-out (FIFO), are accepted practices for determining the basis of shares for capital gains or losses.

The double category method is not a recognized or standard approach within the context of mutual fund shares. Therefore, it cannot be used to correctly establish the basis in this situation.

Understanding the other correct statements provides clarity on how basis can be determined. The cost basis is a common method used to establish the initial value of the investment for tax purposes. Specific share identification allows investors to choose which shares to sell, potentially optimizing tax outcomes. FIFO is a straightforward method that assumes the earliest purchased shares are sold first, impacting the determination of gains or losses based on market fluctuations. These methods are widely accepted and provide investors with legitimate ways to calculate their basis in mutual fund shares.
