presentValue

public double presentValue(double interest,
                           double finalSum,
                           double noOfPeriods)
                    throws ValueReturnYieldDemoException

Method presentValue(double, double, double) as defined in the ValueReturnYield remote interface.

Description copied from the ValueReturnYield interface:

Calculates the initial amount of money which has to be invested within a fixed interest bearing investment in order to accumulate a given final sum.

Parameters:

interest - the fixed rate of interest over all periods expressed in decimal format (i.e. 1 percent = 0.01)

finalSum - the final sum which is required by the investor

presentValue

public double presentValue(double interest,
                           double noOfPeriods,
                           double finalWorth,
                           double rateOfInflation,

                           int days)
                    throws ValueReturnYieldDemoException

Method presentValue(double, double, double, double, int, int) as defined in the ValueReturnYield remote interface.

Description copied from the ValueReturnYield interface:

Calculates the initial amount of money which has to be invested in order to accumulate a given final worth (that is, an inflation adjusted sum) from an fixed interest bearing investment.

Parameters:

interest - the fixed rate of interest paid by the interest bearing investment expressed in decimal format (i.e. 1 percent = 0.01) over each period during the life of the investment

days - the number of days in each period over which the investment is compounded

finalWorth - the value required of the invested asset at the end of the investment periods

rateOfInflation - the (fixed) annual rate of inflation expressed in decimal format (i.e. 1 percent = 0.01)

dayCountConvention - the number of days that the annual inflation is quoted over. For example, the UK/Japan convention uses 365 days whereas the European convention for quoted inflation uses 360 days.

                             double periods)
                      throws ValueReturnYieldDemoException

Method realReturnRepo(double, double, double, double) as defined in the ValueReturnYield remote interface.

Description copied from the ValueReturnYield interface:

Calculates the real return of a Repo agreement when the initial purchase price and the final payment and annual rate of inflation is known.

Parameters:

price - the initial purchase price of the investment asset when the Repo agreement is initiated

finalPayment - the final payment make at the end of the Repo Agreement in order to repurchase the assets

inflation - the rate of inflation in decimal format (i.e. 1 percent = 0.01) over the given period (see description of periods parameter))

periods - the number of the given time peridos used (days, years etc) over which the Repo agreement holds
