### Calculations

#### Profit & Loss statement

The Profit & Loss statement depends on the selected Driver and the Value input.
t < Startt >= Start and t < Endt >= End
Opex = 0Opex.Profit & Loss statement(t) = Driver x ValueOpex = 0
The Profit & Loss statement depends on Indexations.

Indexations help to consider inflation.

When there are yearly expenses with an amount of EUR 24'000, this amount increases because of inflation. The expenses in the first month are EUR 2'000. With an Inflation of 2% and a Inflation Frequency per month the second month expenses are 2'003.30 = EUR 2000 * (1 + 2%)1/12. The Inflation Frequency defines how often the inflation occurs.

Opex costs depend on Cap and/or Floor Bounds.

A Cap or/and Floo value can be added to particular Sales and Opex entities. Dependent from a Driver, a Value for the Cap and Floor bounds is defined. The Floor Values are binding, when the Sales or Opex costs are below the Floor Value. The Cap Values are binding, when the Sales or Opex costs are above the Cap Value.

When a Single amount per Production Unit or per Project is used as Sales or Opex driver, the End date should be Start + 1 months to get a "real" single amount. Otherwise the single amount is divided through the months between start and end. In this case the Cap/Floor value is compared with the single amount divided by the amount of months.

#### Cashflow statement

The Cashflow statement derives from the Profit & Loss statement dependent on the Method of Payment (Mode = Account Payables) respective on the Payment Date (Mode = Pre Payment or Provision).

### Payment Date (Account = Pre Payment)

When Pre Payment is selected as account, a date has to be set with the help of a Date Choice Box. On this date the expense of the whole Project Lifetime is payed. With an expense of EUR 18'000 per year and a Project Lifetime of 20 years, the capital drain on the defined date, in this case 01 / 2016, is EUR 18'000 x 20 years = EUR 360'000. When the defined date is before Transaction, the capital drain will occur at Transaction.

### Payment Date (Account = Provision)

When Provision is selected as account, a date has to be set with the help of a Date Choice Box. On this date the expense of the whole Project Lifetime is payed. With a expense of EUR 18'000 per year and a Project Lifetime of 20 years, the capital drain on the defined date, in this case 12 / 2036, is EUR 18'000 x 20 years = EUR 360'000.

#### Balance Sheet

The Balance Sheet yields from the Balance Sheet logic.

The Balance Sheet gets calculated from the closing Balance Sheet of the previous period and from the difference between the Profit & Loss statement and the Cashflow statement of the actual period.

Balance Sheet(t) = Balance Sheet(t - 1) + Profit & Loss statement(t) - Cashflow statement(t)

The following example explains this functionality:

Cashflow statement480012001200120012
Balance Sheet 480480480480

For 06 / 2016 the book value is calculated as follows:

Balance Sheet(06.2016) = 8 + 4 - 12 = 0

### Properties

Opex costs can be financed internal or external:

Financial assets can be financed internal or external. Internal financing means that all assets are generated by the company itself. An external financing is an outside financing (Debt funding) or an equity financing (for example a Shareholder Loan).
