Basically, you can have "qualified" and "non-qualified" plans at work. A qualified plan qualifies for special tax treatment, it might be called a 401(k), 403(b), 457, 401(a), a traditional pension, or maybe something else. (Each number is the section of tax law that authorizes the plan. An IRA is controlled by a completely different part of the tax code, even though it has similar purposes. A workplace plan will never be an actual IRA.)
If the company also offers a "non-qualified" savings plan, that is basically them offering to set up a savings account for you. Any employer match would be non-qualified, which means it must be included in your W-2 taxable income and subject to social security, medicare and income tax withholding, as if they simply gave you a taxable bonus or raise (which it what it really is). Any interest or dividends would be taxable in the year paid, and you would get a 1099-INT, a 1099-DIV, or something else.
So that may help you figure out what the "PSA" or "PRA" is, are you getting annual interest statements you pay tax on, and are your employer matches included in your taxable income.
