A wholesaler, constructed for this page, goes into liquidation owing its bank US$2.0m, with no security left to realise. Its director has guaranteed US$500,000. The liquidator expects to pay unsecured creditors 30 cents in the dollar; the rate is the example's. The director pays after the liquidation begins, so the bank's claim at that date is the full US$2.0m. Two wordings of the same cap:
Whole debt guaranteed, recovery capped at 500,000
Guarantor pays the bank 500,000
Bank proves for the whole debt 2,000,000 × 0.30 = 600,000
Bank recovers 500,000 + 600,000 = 1,100,000
Guarantor's loss (no proof until bank paid in full) 500,000
500,000 of the debt guaranteed
Guarantor pays the bank 500,000
Guarantor proves for 500,000 500,000 × 0.30 = 150,000
Bank proves for the rest 1,500,000 × 0.30 = 450,000
Bank recovers 500,000 + 450,000 = 950,000
Guarantor's loss 500,000 − 150,000 = 350,000
The total proved in the liquidation is US$2.0m either way, so the dividend rate is unchanged. What moves is who receives the dividend on the guaranteed slice: US$150,000 goes to the bank under the first wording and to the director under the second.
Interest and costs move it again. If the cap reads US$500,000 plus interest from demand and enforcement costs, and the bank's demand goes unpaid for eight months at the example's default rate of 9% a year, the director owes about US$30,000 of interest (500,000 × 9% × 8 ÷ 12) and, say, US$15,000 of costs: US$545,000 against a guarantee the director remembers as US$500,000.
