##### Cost of Elements - Analytical Accounting

The cost estimation using analytical accounting data is performed in two main steps:

- Network cost data;
- Computation of the direct, indirect, common and special costs (common to general and analytical accounting methods).

In order to compute the Network Costs, the following data has to be entered for all the network elements (international transmission, international switch, national transmission, national switch, network access):

- Amortizations, plus other amortizations;
- Amortization period;
- Running and maintenance costs;
- Average Annual Growing Rate.

This data can be entered globally per network segment or in detail (telephonic equipment, energy equipment, buildings and other investments), thanks to a detail window that can be activated by double clicking (or pressing F4) on any field.

Finally, the following data must be entered as global amounts: Other Amortization and Net Fixed Assets.
