The Education and mittee provides study notes to persons preparing
for the examinations of the Society of Actuaries. They are intended to acquaint
candidates with some of the theoretical and practical considerations involved in the
various subjects. While varying opinions are presented where appropriate, limits on the
length of the material and other considerations sometimes prevent the inclusion of all
possible opinions. These study notes do not, however, represent any official opinion,
interpretations, or endorsement of the Society of Actuaries or its Education and
mittee. The Society is grateful to the authors for their contributions in
preparing the study notes.
