Which of the following best describes Non-elective contributions to a 401(k) plan?

Non-elective contributions to a 401(k) plan are defined as contributions made by the employer to the employee's retirement account, which do not require any contribution or deferral from the employee. This means that even if an employee does not choose to make their own contributions to the plan, the employer will still fund a contribution on their behalf.

This type of contribution is often part of the employer's strategy to enhance employee benefits, particularly in settings where employers are looking to promote retirement savings among all employees, regardless of their participation level in the plan. Non-elective contributions can also vary in terms of how they are structured; for example, they can be a flat percentage of compensation or a fixed dollar amount.

Other options imply conditions or voluntary actions that are not characteristics of non-elective contributions. Participation by employees or voluntary contributions implies that action is required from the employee to receive contributions, which is not the case with non-elective contributions since they are made solely at the employer's discretion.
