Regular investments continue unchanged except that if you receive a pay raise and you are investing on a percentage of salary basis, the amount of your ongoing investments will go up proportionately. This also applies to raises received at other times. If you are in the Federal Employees Retirement System, agency contributions also will go up accordingly.
Your allocation of ongoing investments among the funds, and between traditional and Roth investing, also will remain the same unless you change it.
Catch-up contribution investments do not carry over. If you are eligible to make them, you must make a new election each year.
