Payback for Long-Term Borrowing

The elapsed time required to pay back long-term borrowing.

The elapsed time from the beginning of Y1 to the end of the most recent period when Long-Term Borrowing goes non-positive if it has previously been positive. In fact, STEM calculates an interpolated time based on how negative it was at the end of the period compared to how positive it was at the beginning.

Include: Standard

Pen/Connection Demand Ratio

The proportion by which the Penetration is changed due to feedback from the Connection Tariff.

Include: Advanced

Pen/Connection Elasticity

The extent to which a change in the Connection Tariff introduces a change in the Penetration.

The Price Elasticity input.

Include: Advanced

PenConnection Reference Tariff

The connection tariff which qualifies the Penetration input. The actual Penetration is scaled from the input, according to proportional changes in the actual tariff charged compared to the Reference Tariff, to an extent governed by the corresponding Price Elasticity.

The Reference Tariff input.

Include: Advanced

Pen/Rental Demand Ratio

The proportion by which the Penetration is changed due to feedback from the Rental Tariff.

Include: Advanced

Pen/Rental Elasticity

The extent to which a change in the Rental Tariff introduces a change in the Penetration.

The Price Elasticity input.

Include: Advanced

Pen/Rental Reference Tariff

The rental tariff which qualifies the Penetration input. The actual Penetration is scaled from the input, according to proportional changes in the actual tariff charged compared to the Reference Tariff, to an extent governed by the corresponding Price Elasticity.

The Reference Tariff input.

Include: Advanced

Pen/Usage Demand Ratio

The proportion by which the Penetration is changed due to feedback from the Usage Tariff.

Include: Advanced

Pen/Usage Elasticity

The extent to which a change in the Usage Tariff introduces a change in the Penetration.

The Price Elasticity input.

Include: Advanced

Pen/Usage Reference Tariff

The usage tariff which qualifies the Penetration input. The actual Penetration is scaled from the input, according to proportional changes in the actual tariff charged compared to the Reference Tariff, to an extent governed by the corresponding Price Elasticity.

The Reference Tariff input.

Include: Advanced

Penetration

The proportion of a Service’s Customer Base actually connected, which may be influenced by tariff feedback to demand.

The Penetration input, multiplied by the corresponding Connection, Rental and Usage Demand Ratios.

Include: Standard

Period Beginning

The beginning of the period, measured in elapsed years from the beginning of Y1.

Calculated from the built-in periodBegin() function.

Include: Advanced

Period End

The end of the period, measured in elapsed years from the beginning of Y1.

Period Beginning plus Period Length.

Include: Advanced

Period Index

A zero-based index for the periods of the model run.

Include: Advanced

Period Length

The length of the period measured in years.

Calculated from the built-in periodLen() function.

Include: Advanced

Perpetuity Rate

The long-term growth rate used to calculate the terminal value of the network from final-year Free Cashflow, included in the NPV (Perpetuity Rate) result.

Select Constants from the Edit menu in the Results program to change the value of this constant when the Network NPV (Perpetuity Rate) graph is displayed. The graph is updated automatically to reflect the new Perpetuity Rate.

Include: Standard

Personnel Charge

The sum of the Operating Charge for all Resources in a Collection named literally ‘Personnel’, if one has been created in the model. This result features in the predefined graph Network Revenue and Categorised Charges.

You can define similar results for any specific category of cost that you wish to include on a Network graph. (It is only possible to combine both Service and Resource results in order to show a breakdown of revenues or charges in a Network graph).

See 5.17.4 Categorised financials.

Include: Advanced

Planned Units

The additional units of a Resource required to meet the minimum specified by the Planned Units input, beyond those required to satisfy basic demand, and any utilisation or deployment constraints.

Required Units minus Used Units minus Utilisation Units minus Deployment Units.

Include: Standard

Pre-Tax Profit

The annual profit of the network after payment of interest, but before tax and dividends.

Operating Profit plus Interest Income minus Interest Expense.

Include: Essential

Pre-Tax Profit Margin

A measure of the profitability of the business.

Pre-Tax Profit as a proportion of Revenue.

Include: Essential

Present Value of Resource Costs

Include: Standard

Proceeds from Sale of Assets

The positive cash flow item that arises when a Resource is sold (if it has a residual value).

Include: Standard

Profit on Sale of Assets

Arises if a Resource is sold for more than its net book value. This will normally be zero, but could be positive if the Resource is removed early and is sold for a higher price than the original estimated residual value.

The cash received from the sale minus the written-down value of the Resource after its final depreciation.

Include: Standard

Provision Cost

The one-off cost of providing new connections to Services (e.g., assigning a number, setting up billing) independent of Resources used.

For a Service: the product of the Calibration Period per-new-connection Provision Cost input, the normalised Provision Cost Trend and the number of New Connections, including those caused by churn.
