The 1 st consultation process has been scheduled for 5 weeks. This means that stakeholders’ feedback is expected by no later than 6 March 2020. 5 CONFIDENTIAL
The fixed LRAIC model submitted to consultation needs to be understood in the light of the MRP published in 23 October The 1 st draft fixed LRAIC model has been developed following the guidelines stablished in the Model Reference Paper (MRP) published by the DBA in 23 October. The MRP was already consulted from 1 July to 30 August. This consultation starting on 3 February is therefore solely focused on the draft model and not the MRP. Illustrative excerpt of the MRP Illustrative excerpt of the position statement 6 CONFIDENTIAL
To answer to this 1 st consultation process, stakeholders are invited to use the template included in the consultation document Service Providers are requested to disclose their position to each of the questions raised, together with their comments and justifications. DBA kindly requests that stakeholders state their position through the template provided. Illustrative excerpt of the template to comment Position (Agree / Partially Comments and # Category Question Agree / Disagree) justifications Do you agree with the demand considered for the modelled operator? 1 Inputs If you don’t agree, please justify your position and provide supporting information and references. Do you agree with the coverage levels considered for copper, fibre and coax access networks? 2 Inputs If you don’t agree, please justify your position and provide supporting information and references. … … ... 7 CONFIDENTIAL
Some additional indications to the provision of feedback to the 1 st consultation process All comments will have to be submitted by 6 March 2020. • Each stakeholder has to provide only one filled-in template with its position to the questions raised. • Comments should be as precise and brief as possible, while making sure they are justified. • The comments and answers section of the position statement to be produced at the end of this 1 st consultation round will prioritize comments that are i) significant for the results of the model and ii) have been thoroughly justified. Meeting 26 February 2020, deadline for prioritized questions 19 February 2020 • A working session on the fixed LRAIC model will be conducted on 26 February 2020. After this session, DBA will circulate its answers to all questions received. • Questions from stakeholders received by DBA by 19 February 2020 will be prioritized at the meeting. To provide you with the best answers (including relevant illustrations, examples etc), we urge you to send in questions before this date. 8 CONFIDENTIAL

A complete version of the R Model with a sample dataset has been circulated with stakeholders as part of the 1 st Public Consultation Areas included in the sample version of the R model While the sample R model shared with the industry includes all algorithms employed, it has been loaded with inputs from only two random areas* in Denmark in order to: Preserve the confidentiality of the data of the • modelled operator. Shorten execution times, as the R model is • computationally intensive. Stakeholders can analyse the algorithms in this sample R model and assess the reasonability of the results produced for these two sample areas. The complete outcomes of the R model (although with some degree of anonymization) are available in the Excel model. Note (*): Locations of the access nodes included in this area have been randomised as well. 12 CONFIDENTIAL
