portfolio: Constructing a SST Portfolio
In sstModel: Swiss Solvency Test (SST) Standard Models

Description Usage Arguments Note See Also Examples

Constructor for the S3 class portfolio. It allows to build for a sst portfolio containing financial items (market items), insurance items (life and health) as well as a participation.

1 2	portfolio(market.items = NULL, participation.item = NULL, life.item = NULL, health.item = NULL, base.currency, portfolio.parameters)

`market.items`	a list of marketItem S3 objects created using the constructors (see the corresponding help pages for more information): `asset` `cashflow` `liability` `assetForward` `fxForward` `delta` Please refer to the note Section for extra-information.
`participation.item`	a participation S3 object created using the constructor `participation`. This should be expressed in the same currency as `base.currency`.
`life.item`	a life S3 object created using the constructor `life`. The life sensitivities be expressed in the same currency as `base.currency`.
`health.item`	a health S3 object created using the constructor `health`. The health sensitivities be expressed in the same currency as `base.currency`.
`base.currency`	a character value representing the base currency in which the holder of the portfolio reports its results.
`portfolio.parameters`	a list of parameters specific to the portfolio (understood in currency `base.currency`) with entries: `mvm`: market value margin information (MVM), this should be a named list with three numeric fields of length one: `mvm.life`: the market value margin for life; `mvm.health`: the market value margin for health; `mvm.nonlife`: the market value margin for non-life. `rtkr`: risk-bearing capital (RBC) at time 0 run-off, this should be a numeric value of length one. `rtkg`: risk-bearing capital (RBC) at time 0 on-going concern, this should be a numeric value of length one. `credit.risk` the credit risk value, this should be a numeric value of length one. `expected.insurance.result` expected insurance result, this should be a numeric value of length one. `expected.financial.result` expected financial result, this should be a numeric value of length one. `correction.term` correction term, this should be a numeric value of length one.

In order to create an sstModel, the portfolio should contain at least one marketItem. Additionally, we do not allow for a portfolio containing a participation without any marketItem.
