What is the extent of spreadsheet usage by insurers?

Spreadsheets are powerful, versatile and accessible to almost anyone. It is no surprise, therefore, that across all business functions actuaries and other insurance professionals consistently turn to spreadsheets to perform a wide variety of tasks of differing complexity and materiality, ranging from performing simple calculations to using spreadsheets as tools to inform key business decisions.
