Costs included in accounts 6112-6114 and 6211-6565 described in paragraph (c) of this section (§§ 32.6112-32.6114, 32.6211-32.6565 of this chapter) may be treated as avoided retail costs, and excluded from wholesale rates, only to the extent that a party proves to a state commission that specific costs in these accounts can reasonably be avoided when an incumbent LEC provides a telecommunications service for resale to a requesting carrier.
