A 68-year-old retiree deposits a lump sum and begins receiving monthly income checks within 30 days, with payments guaranteed regardless of market performance. Which annuity quadrant describes this product?

Why this is the answer

The four-quadrant annuity framework crosses two independent dimensions: (1) when income starts—immediate (within one payment period of purchase) vs. deferred (accumulation phase first); and (2) who bears investment risk—fixed (insurer guarantees the amount) vs. variable (owner bears market risk through subaccounts). This retiree's contract starts income within 30 days (immediate) and guarantees the monthly check regardless of market performance (fixed), placing it squarely in the immediate-fixed quadrant. Option B is wrong because variable payments fluctuate. Option A is wrong because accumulation is already complete. Option D is wrong on both axes. NAIC Model #245 governs annuity disclosure requirements and defines these distinctions.
