What are the critical issues?
- UDC cost estimates depend on retail service definitions
- UDC cannot anticipate all retail services in advance
- Definitions are a prerequisite to estimating service costs
- All services need not be unbundled immediately
- Service cost estimates need to be reasonable and timely:
- Initial estimates must be reasonable not precise
- Unreasonable cost estimates must have consequences
- Default prices may provide a reasonableness check
- Outsourcing costs may represent a reasonable benchmark
- Non-attributable and insignificant costs can be ignored
