1 EXHIBIT 99.3 PRO FORMA COMBINED FINANCIAL STATEMENTS The unaudited pro forma combined condensed financial statements give effect to the following transactions, which are anticipated to occur on May 29, 1998, (collectively, the "Transactions"): (i) Tesoro Petroleum Corporation (the "Company" or "Tesoro") closes the acquisition (the "Hawaii Acquisition") of all of the outstanding capital stock of BHP Petroleum Americas Refining Inc. and BHP South Pacific Inc. (together, "BHP Hawaii"), both of which are affiliates of The Broken Hill Proprietary Company Limited ("BHP"). The cash purchase price for the Hawaii Acquisition is $275 million, subject to adjustment for an amount by which working capital of BHP Hawaii at the closing date differs from $100 million. In addition, Tesoro will issue an unsecured, non-interest bearing promissory note (the "BHP Note") in the amount of $50 million, payable in five equal annual installments of $10 million each, beginning on the eleventh anniversary date of the closing. (ii)In conjunction with closing the Hawaii Acquisition, Tesoro will borrow funds to finance the cash consideration for the Hawaii Acquisition and refinance substantially all of its existing indebtedness. These borrowings will be financed through term loans and a revolving credit facility which will be fully underwritten by Lehman Brothers. The unaudited pro forma combined condensed financial statements have been prepared from, and should be read in conjunction with, the historical combined financial statements and notes thereto of BHP Hawaii, which are included as Exhibits 99.1 and 99.2 to this Form 8-K, and the historical consolidated financial statements and notes thereto of Tesoro which have been previously filed. The Hawaii Acquisition will be accounted for using the purchase method of accounting for Tesoro's acquisition of BHP Hawaii after giving effect to the pro forma reclassifications and adjustments described in the accompanying notes. The Unaudited Pro Forma Combined Condensed Balance Sheet gives effect to the Transactions as if each had occurred on December 31, 1997. The Unaudited Pro Forma Combined Condensed Statement of Operations for the year ended December 31, 1997 gives effect to the Transactions as if each had occurred on January 1, 1997. BHP Hawaii's results of operations, which are reported on a fiscal year ending May 31, have been adjusted to a December 31 year end. The estimates of the fair value of BHP Hawaii's assets and liabilities are based on valuations that are preliminary. Such valuations will be updated to the closing date of the Hawaii Acquisition and may change from the amounts shown herein; however, the Company does not expect such changes to be material. The unaudited pro forma combined condensed financial statements are intended for informational purposes and are not necessarily indicative of the future financial position or future results of the combined companies or of the financial position or the results of operations that would have actually occurred had the Hawaii Acquisition been in effect as of the date or for the period presented. The Unaudited Pro Forma Combined Condensed Statement of Operations does not reflect any benefits from cost savings or revenue enhancements that are anticipated to result from the integration of operations of Tesoro and BHP Hawaii. There can be no assurance that the Hawaii Acquisition, related financing or any other pending transactions will be consummated. 2 UNAUDITED PRO FORMA COMBINED CONDENSED BALANCE SHEET DECEMBER 31, 1997 Historical Pro Forma Pro Forma Tesoro BHP Hawaii Adjustments Combined --------- ---------- ------------ --------- (In Thousands of Dollars) ASSETS Current Assets: Cash and cash equivalents ...................................... $ 8,352 2,704 (2,704)(a) 8,352 Receivables .................................................... 76,282 56,653 (4,513)(a) 128,422 Inventories .................................................... 87,359 84,331 7,800(b) 179,490 Prepayments and other .......................................... 9,842 3,539 13,381 --------- ------- -------- --------- Total Current Assets ......................................... 181,835 147,227 583 329,645 --------- ------- -------- --------- Property, Plant and Equipment: Refining and marketing ......................................... 370,174 680,332 (467,018)(c) 583,488 Exploration and production ..................................... 291,411 291,411 Marine services ................................................ 43,072 43,072 Corporate ...................................................... 13,689 13,689 --------- ------- -------- --------- 718,346 680,332 (467,018) 931,660 Less accumulated depreciation, depletion and amortization..... 304,523 349,085 (349,085)(c) 304,523 --------- ------- -------- --------- Net Property, Plant and Equipment ............................ 413,823 331,247 (117,933)(c) 627,137 --------- ------- -------- --------- Other Assets ...................................................... 32,150 3,350 (1,008)(d) 47,643 14,200(d) (1,049)(e) -------- 12,143 --------- ------- -------- --------- Total Assets ............................................... $ 627,808 481,824 (105,207) 1,004,425 ========= ======= ======== ========= LIABILITIES AND STOCKHOLDERS' EQUITY Current Liabilities: Accounts payable ............................................... $ 58,767 35,872 94,639 Accrued liabilities and current income taxes payable ........... 31,726 12,667 (3,950)(f) 44,659 6,375(e) (2,159)(g) Current maturities of long-term debt and other obligations...... 17,002 1,007 (15,294)(d) 2,715 --------- ------- -------- --------- Total Current Liabilities .................................... 107,495 49,546 (15,028) 142,013 --------- ------- -------- --------- Deferred Income Taxes ............................................. 28,824 36,086 (36,086)(h) 28,824 --------- ------- -------- --------- Other Liabilities ................................................. 43,211 31,032 (15,858)(f) 58,385 --------- ------- -------- --------- Long-Term Debt and Other Obligations, Less Current Maturities 115,314 8,751 323,724(d) 447,789 --------- ------- -------- --------- Notes Payable to Affiliate ........................................ -- 145,000 (145,000)(a) -- --------- ------- -------- --------- Stockholders' Equity: Common stock ................................................... 4,418 8,208 (8,208)(i) 4,418 Additional paid-in capital ..................................... 190,925 52,362 (52,362)(i) 190,925 Retained earnings .............................................. 140,980 150,839 (150,839)(i) 135,430 (7,709)(d) 2,159(g) Treasury stock .................................................
