What was the difference between the amortized cost and fair value that was due after five years through ten years?
{"Due in one year or less": {"Amortized Cost": 591, "Fair Value": 589}, "Due after one year through five years": {"Amortized Cost": 644, "Fair Value": 642}, "Due after five years through ten years": {"Amortized Cost": 455, "Fair Value": 452}, "": {"Amortized Cost": 1690, "Fair Value": 1683}}
amortized_cost = df["Due after five years through ten years"]["Amortized Cost"]
fair_value = df["Due after five years through ten years"]["Fair Value"]
answer = amortized_cost - fair_value
