6 Exhibit DEF - 2 Page 6 of 6 OATT Transmission Non-Levelized Rate Formula Template Using Form-1 Data Explanatory Notes Note A: Excludes Asset Retirement Obligations from plant balances Note B: Because the Page 2 Rate Base amounts are total system numbers, the wholesale specific loss/reserve balance is grossed up using the relationship between system and wholesale only transmission demands times the percent of the balance applicable to the OATT. See also Notes H and J. Note C: FERC Form 1 page 214 excluding non-transmission related items Note D: Analysis of Company books. Regulatory expense excludes charges by FERC pursuant to 18 CFR Note E: Excludes Retail ECCR and Sebring amortizations from Form-1 reported value Note F: Excludes all income and gross receipts taxes. Labor related other taxes include FICA and unemployment taxes. Property related taxes include county and local property, highway use, and intangible taxes. Note G: Investment in Transmission Energy Control Center included in Schedule 1 Ancillary Service cost. Note H: The allocator "TP" is the percent of allocated gross transmission plant that is OATT related, i.e., after removal of ECC, interconnections and generator step-up transformer investment. Note I: To the extent DEF is authorized by the Florida Public Service Commission and issues bonds for distribution facilities to securitize retail recovery of extraordinary property losses, associated principal and interest expense are excluded in capitalization and return basis. Note J: Functionalized Transmission part Extraordinary Property Losses balance only, "WEPL-T." Consistent with the process described in Note H above, the OATT-related amount of the transmission loss is then derived using the TP allocation factor Note K: Includes Network Integration Service and Network Contract Demand Service Note L: Beginning balance excludes $0 and ending balance excludes $0 for prepaid pensions from Form-1 A/C 165 balances. Note M: If income tax rates change during a calendar year, the income tax rates will be pro-rated based on the number of days each income tax rate was in effect. Note N: Pursuant to the settlement agreement, annual amounts included in line 11 will be adjusted and reversed as necessary to ensure no overfunding of the wholesale reserve; i.e., the year-end reserve balance for OATT rates will not exceed the $8,614,774 shown on line 7 Note O: Payments by DEF to an Affected System Operator pursuant to Orders 2003 or 2006 (including rehearing orders) are not to be included in the formula rate regardless of the accounting. Note P: Target percentages are fixed for and were derived from projected OATT LTF billing MW-months and the MW-month equivalent billings for STF and non-firm transmission revenues in the September 2007 DEF financial forecast. Note Q: Actual LTF OATT MW-Months are the sum of Lines 11 and 12 above, as reported in Form-1 for Firm Network Service for Others and Long Term Firm Point-to-Point Service Note R: Actual STF/Non-Firm equivalent "MW-Months" are equal to monthly STF/Non-firm transmission service revenue divided by the same "Total Firm Monthly Trans. $/MW-Month" rate (Page 1, Line 11) from which the STF/Non-firm billing rates were derived Note S: Section 2.12 of Schedule 10.3 states The Formula Rate excludes all costs that are properly directly assigned or assignable to one or more particular customers, including costs directly assigned or assignable to DEF. Per Settlement of 2008 Annual Update, the amount specified excludes directly assignable retail costs/credits booked to Account 935 and retail sales tax portion of Florida sales tax audit expense booked to Account from Form-1 reported value. DEF will provide, in connection with each Annual Update, a copy of the entire annual actuarial valuation report supporting the derivation of the annual Postretirement Benefits Other than Pensions ( PBOP ) expense as charged to FERC account 926, and the amount of such expense included in Total Admin and General Expenses provided on Exhibit DEF-2, page 3, line 5 of the Formula Rate. DEF will provide, in connection with each Annual Update, a worksheet that shows the actual PBOP expense components and calculation derivation (including, for each account to which PBOP expense is recorded, the account number, expense amount, description, calculation derivation and source). Note T: Network prepayments include interest that has been accrued but not yet refunded. Note U: The inclusion of Line 24, "Unfunded Reserves," ensures that identified "Unfunded Reserves" are appropriately excluded from rate base in the Formula Rate calculations. The specific treatment of these "Unfunded Reserves" in no way precludes the Transmission Provider or interested parties from making any argument in any proceeding at the Commission or in any review or challenge proceeding under the Formula Rate as to the appropriate accounting or ratemaking treatment in the Formula Rate of any unfunded reserve. Note V: Adjusted to remove AFUDC accruals from CWIP projects that were included in rate base. Qualifying CWIP excludes CWIP associated with direct assignment radials. The actual projects are listed on DEF-9. See also Schedules 10-A and Schedule 10.A.4. Note W: Should DEF construct and own radials directly assignable to wholesale customers, DEF shall make a Section 205 filing to amend its Formula Rate Template to remove the costs associated with wholesale direct assignment radials from the calculation of the OATT base rates. A new attachment (e.g., Exhibit DEF-x) shall be added to the template that sets forth the direct assignment radials by customer and by facility, showing the associated monthly balances for gross plant and accumulated depreciation reserves separately by project. The intent is that the accumulated depreciation reserves be maintained separately by customer and by project to capture the associated costs by customer and to reflect the appropriate effect of the vintage of each project. Such Exhibit DEF-x shall be structured to accommodate direct assignments to multiple wholesale customers. Exhibit DEF-2 shall be modified to remove the direct assignment wholesale radials from the base rate calculations in a manner consistent with retail radials, except that Exhibit DEF-2 shall be further modified to set forth separately the costs allocated to each wholesale customer's direct assignment radials in the aggregate in separate columns. Such Section 205 filing shall be made sufficiently in advance of the first occurrence of a direct assignment wholesale transmission radial to permit the requisite modifications to the Formula Rate Template to become effective with the in-service date of the associated facility. Note X: The prepayments allocable to transmission service under the Formula Rate shall exclude prepayments for service and materials under service agreements for the equipment replacement, or operation and maintenance, including refurbishment, of production or distribution facilities of the Company. However, prepayments for such service and materials for Company-owned transmission facilities shall be allocated using the transmission plant allocator. Remaining prepayments shall continue to be allocated on the basis of gross plant investment.
