SECURITIES AND EXCHANGE COMMISSION Washington, D.C. 20549 FORM 8-K CURRENT REPORT Pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 Date of Report (Date of earliest event reported) September 30, 1999 ------------------ SOUTHERN INVESTMENTS UK plc --------------------------- (Exact name of registrant as specified in its charter) England and Wales 333-09033 None ---------------------------------------------------------------------- (State or other jurisdiction (Commission (IRS Employer of incorporation) File Number) Identification No.) 800 Park Avenue, Aztec West, Almondsbury, Bristol BS32 4SE, England -------------------------------------------------------------------- (Address of principal executive offices) Registrant's telephone number, including area code: 011-44-1454-201-101 ------------------- N/A --- (Former name or former address, if changed since last report) Item 2. Acquisition or Disposal of Assets Southern Investments UK plc holds the entire share capital of South Western Electricity plc ("SWE"). On September 30, 1999, SWE completed the sale of its supply business (and certain related activities) to London Electricity plc ("LE") as announced previously in Form 8-K dated June 11, 1999. Under the terms of the agreement, SWE received cash consideration of (pound)160 million, and transferred certain liabilities to LE. Prior to the sale, SWE was primarily engaged in two electric industry segments, distribution, which involves the transfer of electricity from the high voltage transmission system, and its delivery, across lower voltage distribution systems, to consumers; and supply, which involves bulk purchase of electricity and arranging for its sale and transfer to its customers. SWE's operating income is predominantly from the distribution business and this will continue now that the sale of the supply business has been completed. SWE will brand its distribution business as Western Power Distribution as the SWEB name has transferred to LE. Item 7. Pro Forma Financial Information The following unaudited pro forma consolidated statement of income for the year ended March 31, 1999 gives effect to the disposition of the supply business as if the sale had occurred on April 1, 1998. The impact on the consolidated statement of income for the three months ended June 30, 1999, is less than (pound)0.5 million and therefore a pro forma income statement is not presented. The supply business has been treated as a discontinued activity in the reports filed for the periods ended March 31, 1999 and June 30, 1999 and thus the impact of the pro forma adjustments on the results previously reported for these periods is limited. The following unaudited pro forma consolidated balance sheet as of June 30, 1999 gives effect to the disposition of the supply business as if the sale had occurred as of that date. The unaudited pro forma financial statements are presented for informational purposes only and do not purport to be indicative of the financial position which would actually have existed or the results of operations which would actually have been attained if the transaction had occurred in the periods indicated or which may exist or be obtained in the future. These statements should be read in conjunction with the historical financial statements and accompanying notes of the Registrant. 1 SOUTHERN INVESTMENTS UK plc AND SUBSIDIARIES PRO FORMA STATEMENT OF INCOME FOR THE YEAR ENDED MARCH 31, 1999 (In Millions) For the Year Ended March 31, 1999 --------------------------------- As Reported Pro Forma Pro Forma Adjustment (Note 1) OPERATING REVENUES (pound) 261 - (pound) 261 COST OF SALES 16 - 16 ------ ------ ------ GROSS MARGIN 245 - 245 ------ ------ ------ OPERATING EXPENSES: Maintenance 37 - 37 Depreciation and amortization 51 - 51 Selling, general, and administrative 35 - 35 ------ ------ ------ Total operating expenses 123 - 123 ------ ------ ------ OPERATING INCOME 122 - 122 ------ ------ ------ OTHER INCOME (EXPENSE): Interest income 1 - 1 Interest income from affiliated company 6 - 6 Interest expense (55) 1 (54) Investment income 5 - 5 Gain on sale of assets 7 - 7 ------ ------ ------ Total other income (expense) (36) 1 (35) ------ ------ ------ INCOME FROM CONTINUING OPERATIONS BEFORE INCOME TAXES 86 1 87 INCOME TAXES (10) - (10) ------ ------ ------ NET INCOME FROM CONTINUING OPERATIONS 76 1 77 ====== ====== ====== See accompanying notes to unaudited pro forma condensed financial statements. 2 SOUTHERN INVESTMENTS UK plc AND SUBSIDIARIES PRO FORMA CONSOLIDATED BALANCE SHEET AT JUNE 30, 1999 (In Millions) As Reported Pro Forma Pro Forma Adjustment (Note 2) PROPERTY, PLANT, AND EQUIPMENT (pound) 1,466 (a) (45) (pound) 1,421 Less accumulated depreciation 164 (a) (19) 145 ------ ------ ------ Total 1,302 (26) 1,276 ------ ------ ------ OTHER ASSETS: Investments 16 (b) 140 156 Prepaid pension cost 138 (c) (10) 128 Goodwill, net of accumulated amortization of(pound)17 166 - 166 Loans to affiliated company 351 - 351 Premium in respect of loans to affiliated company and related hedges, net of accumulated amortization of(pound)4 38 - 38 ------ ------ ------ Total 709 130 839 ------ ------ ------ CURRENT ASSETS: Cash and cash equivalents 5 - 5 Investments 14 - 14 Receivables: Customer accounts, less provision for uncollectables 57 (d) (22) 35 Other 19 - 19 Materials and supplies 2 - 2 Prepayments 14 - 14 ------ ------ ------ Total 111 (22) 89 ------ ------ ------ TOTAL ASSETS (pound) 2,122 82 (pound) 2,204 ====== ====== ====== See accompanying notes to unaudited pro forma condensed financial statements. 3 SOUTHERN INVESTMENTS UK plc AND SUBSIDIARIES PRO FORMA CONSOLIDATED BALANCE SHEET AT JUNE 30, 1999 (In Millions) As Reported Pro Forma Pro Forma Adjustment (Note 2) STOCKHOLDER'S EQUITY: Common stock, par value (pound)1 per share, 902,128,735 shares authorized, issued and outstanding (pound) 902 - (pound) 902 Retained deficit (136) (e) 116 (20) ------ ------ ------ Total 766 116 882 ------ ------ ------ COMPANY OBLIGATED MANDATORILY REDEEMABLE PREFERRED SECURITIES OF SOUTHERN INVESTMENTS UK CAPITAL TRUST I HOLDING COMPANY JUNIOR SUBORDINATED DEBENTURES 50 - 50 NON-CURRENT LIABILITIES: Long-term debt 301 - 301 Accumulated deferred income taxes 363 (f) 45 408 Provision for loss contracts 68 (g) (68) - Miscellaneous 36 - 36 ------ ------ ------ Total 768 (23) 745 ------ ------ ------ CURRENT LIABILITIES: Commercial paper 30 - 30 Notes payable to banks 304 (b) (20) 284 Notes payable to affiliated company 25 - 25 Other notes payable 7 - 7 Accounts payable 40 (d) (30) 10 Accrued income taxes 54 - 54 Interest accrued 13 - 13 Miscellaneous 65 (h) 39 104 ------ ------ ------ Total 538 (11) 527 ------ ------ ------ TOTAL STOCKHOLDER'S EQUITY AND LIABILITIES (pound) 2,122 82 (pound) 2,204 ====== ====== ====== See accompanying notes to unaudited pro forma condensed financial statements. 4 SOUTHERN INVESTMENTS UK plc AND SUBSIDIARIES FOR THE YEAR ENDED MARCH 31, 1999 AND THE THREE MONTHS ENDED JUNE 30, 1999 NOTES TO THE PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS 1. Income Statement The pro forma adjustment to the consolidated statement of income for the year ended March 31, 1999, reflects a reduction in interest expense resulting from short-term debt repayment of (pound)20 million, at an interest rate of 7.9%. 2. Balance Sheet The pro forma adjustments to the consolidated balance sheet as of June 30, 1999 reflect the following: a) Disposition of the supply business fixed assets, and write-down of assets used in the supply business. b) Adjustment to reflect proceeds from the sale of the supply business, of which (pound)140 million was temporarily invested in short term investments, and (pound)20 million was utilized to reduce short-term debt. A longer term investment is anticipated. c) Disposition of the supply business prepaid pension credit. d) Disposition of supply business accounts receivable and accounts payable, and to record accounts receivable from the supply business which were previously eliminated in consolidation. e) The recognition of the anticipated gain from the sale and related income taxes. f) Adjustment to reflect the estimated income tax charge related to the gain on sale. g) SWE entered into a contract relating to the purchase of 200 megawatts of capacity from a 7.69% related party, Teesside Power Limited, for a period of 15 years beginning April 1993. SWE had recognized an accrual at the acquisition date for the excess of these Teesside power purchase costs in each period over an estimate of the equivalent wholesale market cost in that respective period. Under the terms of the supply sale agreement, LE will assume SWE's obligations under the contract and thus the accrual is released. h) Disposition of supply business accruals, and to reflect expenses that are incremental and a direct result of the sale of the supply business. 5 SIGNATURE Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorised.
