Final answer:
The false statement about stock bonus plans is that participants of a stock bonus plan must have the right to demand employer securities on plan distributions.
Step-by-step explanation:
The statement that is false about stock bonus plans is that participants of a stock bonus plan must have the right to demand employer securities on plan distributions. It is important to note that stock bonus plans are a form of employee benefit plan where employees receive company stock as a bonus, usually as part of their compensation package.
However, participants in a stock bonus plan do not have the right to demand employer securities on plan distributions. The other statements are true: a coda can be attached to a stock bonus plan, and stock bonus plans have a deductible contribution limit of 25 percent of compensation.
