Regular pension payments are periodic distributions. Yes.

This will be the default option on pension arrangements, unless companies are trying to settle with pensioners for lump-sum amounts that will lessen the plan’s long term liability. The options for periodic distributions will always be for periods less than or up to a year in length.

Periodic distributions can help you sleep better at night, knowing that you have a fixed stream of income for the rest of your life. It may not be enough to sustain your lifestyle completely, but it will give you a sense of financial security and prohibit overspending in a way that the lump-sum distribution does not.
