According to Bob Scott in the New England Actuarial Review Class, D'Arcy =
is outdated and Troxel is correct. Also Troxel includes a Gross Written =
Premium to Surplus Test that D'Arcy does not include because it is new.

Subject: NAIC IRIS Ratios

On this exam, we have two different source readings which discuss the =
NAIC=20
IRIS Ratios. One of them is the D'Arcy article, and the other is the =
Troxel=20
and Bouchie article. There are some discrepancies with regard to the =
"usual=20
ranges" of these ratios. For example,

(3) Surplus Aid to Surplus:
D'Arcy: <25%
Troxel: <15%

(5) Investment Yield:
D'Arcy: >5%
Troxel: between 4.5% and 10%

(9) One Year Reserve Development to Surplus:
D'Arcy: <25%
Troxel: <20%

(10) Two Year Reserve Development to Surplus:
D'Arcy: <25%
Troxel: <20%

According to the Syllabus, D'Arcy was published 1996, and Troxel was=20
published in 1995, so I would be inclined to believe the former rather =
than=20
the latter. However, the D'Arcy paper was part of the Foundations book,=20
which was re-released in 1996, and it is possible that the IRIS values =
were=20
not updated for the new release. Do any of you know for sure?
