Change in Total Borrowing

Variations in the amount of overdraft and long-term borrowing between two consecutive years.

The difference between Total Borrowing for the current year and the previous year, taking the Initial Long-Term Borrowing input minus the Initial Current Account input (if negative) as the value for the beginning of year zero.

Include: Standard

Change in Working Capital

Variations in the net amount of money owed to the business, used to calculate cashflows.

The difference between Working Capital for the current year and the previous year.

Include: Standard

Churn Cost

The explicit financial impact of the turnover in connections to Services.

For a Resource: the product of the Calibration Period per-unit Churn Cost input, the normalised global and Resource Churn Cost Trends, the Churn Age Factor and the respective Churn Proportions and usage by Services, divided by the Capacity.

Include: Standard

Churn Proportion

The Churn Proportion input, defined as an explicit result for easier reference in derived-result definitions.

Include: Standard

Churn Revenue

The one-off revenue collected for churned connections to a Service.

The product of the number of Connections, the Churn Proportion and the Churn Tariff.

Include: Standard

Churn Tariff

The one-off tariff charged per churned connection.

The Churn Tariff input.

Include: Standard

Connection Charge Multiplier

The margin applied to a Service’s cost per new connection, fed back from the previous year, in order to calculate the cost-dependent connection tariff for the current year.

The Charge Multiplier input.

Include: Advanced

Connection Cost

The one-off non-capitalised cost of leasing Resources.

For a Resource: the product of the Calibration Period per-unit Connection Cost input, the normalised global and Resource Connection Cost Trends, and the number of Incremental Units.

Include: Standard

Connection Cost Dependent Tariff

The cost-dependent part of the composite Connection Tariff.

The Connection Feedback Cost multiplied by the Charge Multiplier input.

Include: Advanced

Connection Cost Independent Tariff

The cost-independent part of the composite Connection Tariff.

The Cost Independent Tariff input.

Include: Advanced

Connection Feedback Cost

The cost per new connection, fed back from the previous year, in order to calculate the cost-dependent connection tariff for the current year.

The proportion of costs allocated to a Service, earmarked for the connection tariff, divided by the number of New Connections, including those arising from churn (both in the previous year).

Include: Advanced

Connection Independence Weighting

The factor used to weight the cost-independent part against the cost-dependent part when calculating the composite Connection Tariff.

The Independence Weighting input.

The number of New Connections multiplied by the Connection Tariff.

Include: Standard

Connection Tariff

The one-off tariff charged per new connection to a Service.

The weighted average of the cost-independent and cost-dependent connection tariffs, calculated according to the Independence Weighting. If the weighting is 1 (the default), this result is just the cost-independent Connection Tariff input.

For a Service: the Average Creditor Days input multiplied by the average daily Operating Costs (i.e., Operating Costs divided by 365).

Note: The Creditors result is calculated from Operating Costs rather than Operating Expenditure – in line with the Current Account calculation – on the basis that deferred payment on capital investment is effectively a form of long-term borrowing. The Creditors result should only relate to short-term supplier payables.
