• analysis at <str<strong>on</strong>g>the</str<strong>on</strong>g> level of individual undertakings; and<br />
• generalised analysis that can be applied across <str<strong>on</strong>g>the</str<strong>on</strong>g> industry.<br />
In <str<strong>on</strong>g>the</str<strong>on</strong>g> following paragraphs, are fur<str<strong>on</strong>g>the</str<strong>on</strong>g>r analysed <str<strong>on</strong>g>the</str<strong>on</strong>g>se two steps<br />

B.25 Defining UR% mortality as <str<strong>on</strong>g>the</str<strong>on</strong>g> quotient of UR mortality and <str<strong>on</strong>g>the</str<strong>on</strong>g> corresp<strong>on</strong>ding<br />
volume measure TP0 or CR0, it can be seen that <strong>on</strong> an abstract level<br />

<str<strong>on</strong>g>the</str<strong>on</strong>g> formula in <str<strong>on</strong>g>the</str<strong>on</strong>g> preceding paragraph, <strong>on</strong>e needs <str<strong>on</strong>g>to</str<strong>on</strong>g> know <str<strong>on</strong>g>the</str<strong>on</strong>g><br />
probability distributi<strong>on</strong> of <str<strong>on</strong>g>the</str<strong>on</strong>g> random variable UR% mortality . On a practical<br />
level, it may be assumed that this distributi<strong>on</strong> is of a type that is<br />
completely specified by its first two moments. Then β may be<br />
determined <strong>on</strong>ce <str<strong>on</strong>g>the</str<strong>on</strong>g> following has been specified<br />
• <str<strong>on</strong>g>the</str<strong>on</strong>g> type of <str<strong>on</strong>g>the</str<strong>on</strong>g> distributi<strong>on</strong>;<br />
• its expected value µ; and<br />
• its variance σ 2 .<br />
B.27 Assuming that <str<strong>on</strong>g>the</str<strong>on</strong>g> type of distributi<strong>on</strong> of UR% mortality is set by <str<strong>on</strong>g>the</str<strong>on</strong>g><br />
supervisor, <str<strong>on</strong>g>the</str<strong>on</strong>g> determinati<strong>on</strong> of its expected value and variance allows<br />
for a wide range of approaches, which vary in <str<strong>on</strong>g>the</str<strong>on</strong>g>ir degree of<br />
pers<strong>on</strong>alisati<strong>on</strong>:<br />
• all parameters are set by <str<strong>on</strong>g>the</str<strong>on</strong>g> supervisor; <str<strong>on</strong>g>the</str<strong>on</strong>g> result would be a<br />
table of industry-wide fac<str<strong>on</strong>g>to</str<strong>on</strong>g>rs β and γ for mortality risk that can<br />
be applied <str<strong>on</strong>g>to</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> insurers’ provisi<strong>on</strong>s in each segment; or<br />
• <str<strong>on</strong>g>the</str<strong>on</strong>g> expected value and/or variance of <str<strong>on</strong>g>the</str<strong>on</strong>g> distributi<strong>on</strong> are<br />
computed using company-specific data; or<br />
• <str<strong>on</strong>g>the</str<strong>on</strong>g> expected value and/or variance of <str<strong>on</strong>g>the</str<strong>on</strong>g> distributi<strong>on</strong> are<br />
computed using a mixture of company-specific data and data<br />
which is set by <str<strong>on</strong>g>the</str<strong>on</strong>g> supervisor.<br />
