Abstract: A computing device programmed to receive and use event data, such as hurricane, earthquake, fire, flood, and storm event data, and map that data to computer display map along with insured data related to an insurance portfolio that can also be mapped by geographic area and value, so that a user can quickly determine the exposure to a portfolio from an event. The event can be either a real-time event or a historical event.

Abstract: A computer system configured to evaluate a portfolio comprising instruments, comprising a computer memory configured to store, for each instrument, an instrument value for each portfolio scenario in an n-dimensional matrix, a first constraint and a second constraint; and a computer processor configured to transpose the n-dimensional matrix, to determine a first solution by maximizing the product of transpose of the n-dimensional matrix and the first constraint, determine whether the first solution is within an accepted range of an acceptable risk, if the expected first solution is not within an accepted range of an acceptable risk, process the second constraint with the first solution to obtain a second solution, and determine whether the second solution is within the accepted range of the acceptable risk.
