       On May 30, 1997 Tidewater Inc. ("the Company") filed a Form 8-K dated
May 16, 1997 containing a description of the Company's acquisition of O.I.L.
Limited.  This Form 8-K/A-1 amends and restates the disclosure in Item 7(a) and
(b) of the Company's Form 8-K filed on May 30, 1997 to include the financial

Item 2.       Acquisition or Disposition of Assets.

Acquisition of the O.I.L. Group of Companies

       On May 16, 1997, the registrant, Tidewater Inc. (the "Company"),
acquired all of the ordinary shares of O.I.L. Limited and its related
international marine operating companies (the "O.I.L. Group") from Ocean Group
plc and its affiliates (collectively the "Ocean Group") in exchange for a cash
payment of 328 million pounds sterling (approximately U.S. $534 million).  In
addition, a 3 million pound sterling (approximately U.S.$5 million) advance
payment was made for the net working capital of O.I.L. Group, with the final
purchase price to be adjusted for the final net working capital of O.I.L. Group
as of the May 16, 1997 closing date.  The consideration paid Ocean Group was
determined through arm's length negotiations between the Company and Ocean
Group.  The Company used approximately $39 million of its cash to fund the
purchase price, with the remainder provided by borrowings under a bank credit
facility.

       Prior to consummation of this acquisition, the O.I.L. Group was
principally engaged in the business of operating approximately 100 marine
vessels, primarily platform supply and anchor handling towing supply vessels,
in several international offshore oil and gas exploration areas outside of the
United States.  The Company intends for the foreseeable future to continue to
engage in such operations.

       The acquisition was completed on May 16, 1997, as announced in the press
release which has been filed as an exhibit to this report.  Additional
information relating to the acquisition is set forth in the Agreement for the
Acquisition of Share Capital of the O.I.L. Group of Companies, a copy of which
has also been filed as an exhibit to this report.

Item 7.       Financial Statements, Pro Forma Financial Information and
              Exhibits.

          Unaudited Pro Forma Condensed Combined Financial Statements



INTRODUCTION

       The following unaudited pro forma condensed combined financial
statements give effect to the May 16, 1997 acquisition (the "Acquisition") of
all of the ordinary shares of O.I.L. Limited and its related international
marine operating companies (the "O.I.L. Group") from Ocean Group plc and its
affiliates.

       The unaudited pro forma condensed combined financial statements should
be read in conjunction with the historical financial statements of Tidewater
Inc. and subsidiaries and O.I.L. Group and notes thereto.  This pro forma
information is presented for illustrative purposes only and is not necessarily
indicative of the results which actually would have been obtained if the
Acquisition had been effected on the pro forma dates, nor is it necessarily
indicative of future results.

       The unaudited pro forma condensed combined financial statements are
based upon the purchase method of accounting for the Acquisition.  The
Unaudited Pro Forma Condensed Combined Statement of Earnings for the year ended
March 31, 1997 assumes that the Acquisition was effected on April 1, 1996.  The
Unaudited Pro Forma Condensed Combined Balance Sheet as of March 31, 1997
assumes that the Acquisition was effected on that date.

       The Unaudited Pro Forma Condensed Combined Statements of Earnings have
been compiled from the Tidewater Inc. audited Consolidated Statement of
Earnings for the year ended March 31, 1997 and the O.I.L. Group audited
Statement of Profit for the year ended December 31, 1996.  Tidewater's fiscal
year end is March 31, while O.I.L. Group's is December 31.  The Unaudited Pro
Forma Condensed Combined Statement of Earnings for the year ended March 31,
1997 includes O.I.L. Group's audited financial information for the 12 months
ended December 31, 1996.  During the period from January 1, 1997 through March
31, 1997, revenues of O.I.L. Group amounted to approximately $38 million.  The
Unaudited Pro Forma Condensed Combined Balance Sheet as of March 31, 1997
includes O.I.L. Group's audited financial information as of December 31, 1996.


PURCHASE PRICE

       The cash purchase price of the Acquisition was approximately $539
million, inclusive of a $5 million advance payment for the net working capital
of O.I.L. Group, which is subject to adjustment based upon a final balance
sheet prepared as of the May 16, 1997 closing date.  The source of the funds
used for the Acquisition consisted of $39 million from cash balances with the
remainder from borrowings under a Revolving Credit and Term Loan Agreement with
a group of banks.

Notes to Unaudited Pro Forma Condensed Combined Statements of Earnings:

(a)  To adjust interest expense to reflect the $500 million of debt incurred as
     a result of the O.I.L. Group acquisition.  In accordance with terms of the
     Company's debt agreement, principal payments are assumed to be
     approximately $14.3 million per quarter and the interest rate is assumed
     to be 6.85%.  The adjustment also includes amortization of financing costs
     associated with the debt (amortized primarily over seven years).
(b)  To adjust interest expense incurred by O.I.L. Group on indebtedness to
     Ocean Group which, by agreement, is excluded from the acquisition.
(c)  To adjust interest income to reflect the assumed beginning-of-the-year
     usage of $39 million of cash in the O.I.L. Group acquisition.  Interest
     yield on cash investments is assumed to be 5%.
(d)  To adjust for additional depreciation on the new basis of properties and
     equipment acquired in the O.I.L. Group acquisition.  Adjustment also
     includes amortization of $356 million of cost in excess of fair value of
     the net assets acquired in the transaction (amortized over 40 years).
(e)  To adjust income taxes of the pro forma combined group to Tidewater's
     historical effective income tax rate, as adjusted for tax effects related
     to the acquisition.
(f)  The pro forma combined information does not include the operating and
     general and administrative cost savings anticipated as a result of the
     consolidation of marine operations.
(g)  The historical results of operations of O.I.L. Group were reported in
     British pounds sterling and converted for purposes of the pro forma
     financial information at the average currency exchange rate applicable
     during the reporting period.

                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors of O.I.L.:

We have audited the accompanying combined balance sheets of O.I.L. Group, a
former division of Ocean Group plc (Ocean Group), as of December 31, 1996 and
1995 and the related combined statements of profit, cash flows and total
recognised gains and losses for each of the years in the three year period
ended December 31, 1996 all expressed in British pounds sterling. These
combined financial statements are the responsibility of the O.I.L. Group
management. Our responsibility is to express an opinion on these combined
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards in the United Kingdom, which do not differ in any significant respect
from auditing standards generally accepted in the United States. Those
standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the combined financial statements audited by us present fairly,
in all material respects, the financial position of O.I.L. Group at December
31, 1996 and 1995, and the results of its operations and cash flows for each of
the years in the three year period ended December 31, 1996 in conformity with
accounting principles generally accepted in the United Kingdom.

Accounting principles generally accepted in the United Kingdom vary in certain
significant respects from accounting principles generally accepted in the
United States. The application of the latter would have affected the
determination of results of operations expressed in British pounds sterling for
each of the two years in the period ended December 31, 1996 and the
determination of combined invested equity also expressed in British pounds
sterling at December 31, 1996 and 1995 to the extent summarised in Note 28 to
the combined financial statements.

O.I.L. Group is a division of Ocean Group and, as disclosed in the combined
financial statements, has transactions and relationships with Ocean Group and
its affiliates.

                                  O.I.L. GROUP
                   NOTES TO THE COMBINED FINANCIAL STATEMENTS

                              ACCOUNTING POLICIES

The accounting policies adopted by the O.I.L. Group are set out below, and have
been consistently applied throughout the period.

     (a)      ACCOUNTING CONVENTION

              The accounts are prepared under the going concern concept and the
              historical cost convention and in accordance with applicable
              accounting standards.

     (b)      BASIS OF PREPARATION

              For the period covered by these combined financial statements,
              O.I.L. Group ("The Group") was a division of Ocean Group plc
              ("Ocean Group"). O.I.L. Group comprises O.I.L. Limited, its
              direct subsidiaries and other Ocean Group subsidiaries providing
              marine and other services to the offshore oil industries (see
              note (d) below). Each of the companies is a legal entity and
              prepares single company statutory accounts according to the
              legislation requirements of its country of registration or
              incorporation.

              The operations of this division have been reported as a separate
              segment within the financial statements of Ocean Group.

              Under the terms of the acquisition of O.I.L. Group (see Note 27),
              Tidewater Inc has acquired the whole of Ocean Group's holdings of
              the issued share capital of the companies comprising the O.I.L.
              Group. However, the operations of O.I.L. Limited's supply base in
              Lerwick (the Shetland division) were excluded from the sale. For
              the purposes of these combined financial statements, the results
              and net assets of the Shetland division have been excluded for
              all periods.

              These combined financial statements present information about the
              O.I.L. Group on a combined basis. All material intercompany
              accounts and transactions have been eliminated in arriving at the
              combined financial statements.

              The combined cash flow statement presented above has been drawn
              up for the purposes of these combined financial statements under
              Financial Reporting Standard No 1 (Revised 1996). 

              Subsidiary Undertakings

              An undertaking is considered to be a subsidiary where the Group
              exercises dominant influence over the operations of the
              undertaking. The accounts of subsidiary undertakings acquired
              during the year are included in Group figures from the effective
              dates of acquisition.

              Goodwill

              No goodwill was incurred on the acquisition of any of the
              subsidiaries included within these combined financial statements.

                                  O.I.L. GROUP
             NOTES TO THE COMBINED FINANCIAL STATEMENTS (continued)

     (c)      INVESTMENTS IN ASSOCIATED UNDERTAKINGS

              Associated undertakings are undertakings in which the Group has a
              long term participating interest and over which it exercises
              significant influence.

              The Group combined profit and loss account includes the Group's
              share of the results of its associated undertakings as shown by
              their audited accounts or unaudited management accounts. The
              Group's investment in associated undertakings is its interest in
              their tangible net assets.

     (d)      NATURE OF BUSINESS

              Nature of operations

              The O.I.L. Group provides marine and other services to the
              offshore oil industries on the UK Continental Shelf, in Africa,
              Asia Pacific and South America. These services include
              transporting supplies, material and personnel; towing mobile rigs
              and construction barges; positioning and handling anchors of
              mobile drilling rigs and construction and pipe laying barges;
              diving and maintenance support; oil terminal support operations;
              steel fabrication work for small-scale repair and modification of
              fixed drilling installations; and related marine consultancy
              services. O.I.L. Group's main customers are among the major
              international oil exploration and production companies or their
              immediate service contractors.

              Related party transactions

              As a division of Ocean Group, O.I.L. Group received a number of
              administrative and support services from Ocean Group and
              participated in the Ocean Group pension schemes, insurance and
              banking arrangements and employee share ownership plans.

              Further information about such relationships and transactions is
              given in Note 17.

     (e)      FOREIGN CURRENCY RISK MANAGEMENT

              O.I.L Group has utilised the central treasury functions of the
              Ocean Group in managing its cash and borrowings and in hedging
              its asset and transaction foreign exchange exposures as part of
              the Ocean Group's overall treasury management strategy.

              For the purposes of these combined financial statements, where
              this hedging strategy has generated profits or losses within the
              records of Ocean Group which relate to O.I.L. Group exposures,
              these have been pushed down and included in the results of O.I.L.
              Group. The impact on the net assets of the O.I.L.Group has been
              adjusted through the intercompany account with Ocean Group.

                                  O.I.L. GROUP
             NOTES TO THE COMBINED FINANCIAL STATEMENTS (continued)

     (f)      TANGIBLE  FIXED ASSETS

              Tangible fixed assets are stated at cost less depreciation. Cost
              includes interest incurred on the financing of the construction
              of major vessels. Depreciation of fixed assets is provided evenly
              over their estimated useful lives after taking account of
              estimated residual values. Useful lives are assessed as follows:

              Vessels                              5 to 25 years
              Plant and equipment                  3 to  5 years
              Motor vehicles                             4 years
              Short leasehold property           period of lease
              Long leasehold property                   20 years
              Buildings                           10 to 25 years

              Depreciation is not charged in respect of freehold land.

              Change of asset lives:

              In 1995 the estimated maximum useful life of vessels was
              reassessed and extended from 20 to 25 years and the estimated
              residual value decreased from 10% to nil. This decreased the
              depreciation charge for 1995 by L.1,701,000.

     (g)      PROFIT ON SALE OF VESSELS

              Profit on the sale of vessels, which represents the total profits
              made on sale of vessels to third parties, is recognised when the
              consideration is realised. Any losses on the sale of vessels are
              recognised at the time of disposal.

     (h)      TAXATION

              Historically, Ocean Group has undertaken to discharge the
              liabilities to UK Corporation Tax of the UK entities included in
              the O.I.L. Group and as a result no charges or obligations for UK
              corporation tax have been recorded in the individual companies'
              statutory accounts.

              This financial information presents the O.I.L. Group's UK
              corporation tax charge on a stand alone basis. No benefit has
              been assumed from corporation tax losses or Advanced Corporation
              Tax arising in other Ocean Group undertakings.

              UK Corporation Tax obligations are included within balances
              payable to Ocean Group as Ocean Group have been responsible for
              their payment.

              Overseas tax payable represents amounts outstanding on
              assessments received and payable by O.I.L. Group without recourse
              to Ocean Group.

     (i)      DEFERRED TAX

              Provision for deferred taxation is made using the liability
              method, on the excess of capital allowances over depreciation and
              other timing differences, to the extent that it is probable that
              a liability will crystallize in the foreseeable future.

             NOTES TO THE COMBINED FINANCIAL STATEMENTS (Continued)


     (j)      FOREIGN CURRENCIES

              The trading results of foreign operations are translated into
              sterling at average rates of exchange ruling through the relevant
              period. The net assets of foreign operations are expressed in
              sterling at the rates of exchange ruling at the balance sheet
              date.

              Differences on exchange arising from the retranslation of both
              the opening net assets of foreign operations and of the trading
              results of foreign operations to closing rates of exchange are
              taken to reserves.

              Other assets and liabilities denominated in foreign currencies
              are expressed at the rates of exchange ruling at the balance
              sheet date. Profits or losses due to currency fluctuations,
              including those arising on the settlement of day to day
              transactions, are dealt with through the profit and loss account.

     (k)      PENSIONS

              Certain O.I.L. Group employees are members of an Ocean Group
              pension scheme (a defined benefit plan) contributions to which
              are assessed by a qualified actuary based on the cost of
              providing pensions across all participating Ocean Group
              companies.

              Contributions on behalf of those O.I.L. Group employees who are
              members of the Merchant Navy Officers and Ratings Pension Funds
              (defined contribution plans) are charged to the profit and loss
              account as incurred. These schemes are operated independently on
              behalf of the UK Merchant shipping industry and the contribution
              rates required are determined by actuarial review.

     (l)      STOCKS

              Stocks are stated at the lower of cost and net realisable value.

     (m)      LEASES

              The rental costs arising from operating leases are charged
              against profit before interest as they arise.

</TABLE>

        UK Corporation Tax payable is included in creditors falling due within
        one year in amounts owed to group undertakings.

        UK Corporation Tax is assessed on the profits of O.I.L. Limited arising
        on its worldwide income less an allowance for double taxation relief
        where these profits are subject to overseas tax. No relief is available
        for any interest or penalties suffered. Exposures may exist in relation
        to the O.I.L. Group's overseas operations arising from the late payment
        of overseas tax . No provision has been made in these financial
        statements for any additional overseas tax or penalties which may
        become payable but which are not quantifiable at this time within a
        reasonable range of outcomes. Under the terms of the acquisition (Note
        27), O.I.L. Group is not liable for any further charges for overseas
        taxation and associated interest or penalties for any periods up to and
        including 31 December 1996.

        The effective rate of tax is lower than the statutory UK Corporation
        Tax rate of 33% primarily because of the availability of tax relief for
        capital expenditure for which no deferred tax charge is considered
        necessary under UK GAAP.

   7    DIVIDENDS

        Dividends payable in 1996 by O.I.L. Limited, O.I.L. Engineering Limited
        and Fairway Personnel Services Limited reduced profit and loss reserves
        of these companies to L.nil.

        Dividends declared and payable by the O.I.L. Group to Ocean Group
        disclosed within these combined financial statements represent the
        aggregated amounts reflected in the underlying statutory accounts, as
        approved by the respective Boards of Directors subsequent to each year
        end.

          parties at cost.

   (c)    Malaysian subsidiaries

          During 1996, O.I.L. Limited sold one vessel to each of Ocean Fleets
          Sdn Bhd and Ocean Fleets 2 Sdn Bhd at arms length valuations
          generating a profit of L.768,000 and L.797,000
          respectively. This profit has been eliminated on consolidation.

          Third party loans held by Ocean Fleets Sdn Bhd and Ocean Fleets 2 Sdn
          Bhd for the purchase of these vessels are guaranteed by Ocean Group.

          The vessels are chartered back to O.I.L. Limited on bare boat charter
          at arms length rates.

   (d)    O.I.L. (Nigeria) Limited

          O.I.L. (Nigeria) Limited, a 60% subsidiary of the O.I.L. Group
          provides marine and terminal services to O.I.L. Limited in Nigeria.
          These services are charged at uplifted rates as determined by
          contract.

   18     FOREIGN CURRENCY RISK MANAGEMENT

          The O.I.L. Group hedges its exposure to currency risk through foreign
          exchange loans and forward contracts to purchase and sell foreign
          currencies.

          Hedging of Foreign currency debtors:

          During 1994 and 1995, O.I.L. Limited held an external loan of US$14
          million to hedge the company's exposure to US dollar denominated
          trade debtors. Interest was paid on this loan at market rates.
          Exchange movements recorded in the profit and loss account in
          relation to this loan were L.520,000 gain in 1994 and
          L.110,000 loss in 1995. On 29 December 1995, this loan was
          repaid in full. At that date, this hedge was replaced by notional US
          dollar forward contracts with Ocean Group, adjusted on a monthly
          basis to reflect the projected value of US dollar debtors. Within
          Ocean Group, specific forward contracts were taken out to hedge this
          US dollar exposure. These combined financial statements reflect the
          push down of the gain recorded by Ocean Group in relation to
          forward contracts in 1996 which amounted to L.844,000.

          Hedging of Foreign currency transactions:

          During 1994 and 1995, the O.I.L. Group exposure to foreign currency
          transaction flows was hedged against the exposure to foreign currency
          transaction flows in other Ocean Group divisions. This hedging was
          reflected by O.I.L. Group as notional forward contracts taken out
          with Ocean Group. The notional gains arising from these notional
          forward contract hedges during 1994 and 1995 of L.815,000 and
          L.395,000 respectively have not been pushed down into the
          results of the O.I.L. Group. During 1996, formal forward intergroup
          contracts were executed between O.I.L. Limited and Ocean Group plc
          and accounted for within the results of O.I.L. Group, giving rise to
          a net result of L.nil.

   (b)    Guarantees:

          O.I.L. Limited together with other subsidiary undertakings of Ocean
          Group plc are guarantors to a revolving credit facility available to
          Ocean Group plc and nominated subsidiary undertakings. The
          outstanding joint liability at 31 December 1996 was L.10,000,000
          (1995 : L.20,024,000). Subsequent to the acquisition of O.I.L. Group
          by Tidewater Inc (Note 27), O.I.L. Group is no longer a party to this
          guarantee. 

   (c)    Forward exchange contracts

          The O.I.L. Group had no outstanding forward exchange contracts at 31
          December 1996 or 31 December 1995.

   21     PENSION COSTS

          The Ocean Group participates in the Ocean Nestor Pension Scheme. This
          scheme is of the defined benefit type providing benefits to certain
          employees within the Ocean Group. The assets of this scheme are
          administered by an independent external trustee and are held
          separately from the Ocean Group's assets.

          The pension cost of this scheme has been assessed with the advice of
          an independent qualified actuary using the projected unit method. The
          last full actuarial valuation of this scheme was carried out as at 31
          March 1995. As a result of this valuation, the actuary has been able
          to recommend the continued suspension of Ocean Group's contributions
          to this scheme. This payment holiday has been in operation throughout
          the three years to 31 December 1996.

          No charge is recorded for this scheme in these combined financial
          statements. No adjustment has been made to recognise a share of the
          overall scheme surplus as no ongoing benefit will accrue to O.I.L.
          Group. Pursuant to the sale agreement, Tidewater is to contribute to
          the Ocean Nestor Pension Scheme at a rate of 10% of pensionable
          salary for all contribution members for a period of up to six months
          from the date of sale. The maximum liability for pension
          contributions anticipated to be made by Tidewater over this period
          amounts to L.120,000.

          Pension costs paid by O.I.L. Group comprise contributions to the
          Merchant Navy Pension Funds defined contribution schemes. The charge
          included within the profit and loss account in relation to these
          schemes was 1996 - L.10,000; 1995 - L.29,000; 1994 -
          L.171,000.

          No account has been taken of surplus Advance Corporation Tax ("ACT")
          held by Ocean Group as this will not be available to the O.I.L. Group
          on an ongoing basis. Dividends paid by the O.I.L. Group to Ocean
          Group were paid under a group income election and therefore were not
          subject to ACT.

          Capital gains arising on the disposal of vessels have been offset
          against available capital losses within Ocean Group. No deferred tax
          liability has been assessed in respect of such gains for which
          rollover relief might have been claimed on an O.I.L. Group stand
          alone basis.

   26     INTERCOMPANY TRANSACTIONS

          The cash flow impact of the movement in intercompany balances
          excluding hedging loans and trading balances includes movements in
          relation to UK corporation tax, dividend payments and movements of
          funds between O.I.L. Group and Ocean Group.

          Movements in current account balances which arise from trading are
          included within the reconciliation of net cash inflow from operating
          activities.

   27     SUBSEQUENT EVENT

          On 20 March 1997 Ocean Group entered into an agreement with Tidewater
          Inc for the sale of the O.I.L. Group. The sale was completed on 16

                                  O.I.L. GROUP
             NOTES TO THE COMBINED FINANCIAL STATEMENTS (continued)


   28     DIFFERENCES BETWEEN UK AND US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES

          The O.I.L. Group's combined financial statements have been prepared
          in accordance with generally accepted accounting principles in the
          United Kingdom ("UK GAAP") which differ in certain respects from
          generally accepted accounting principles in the United States ("US
          GAAP"). The material differences as they apply to the Group are
          summarised below.

   (a)    Deferred taxation

          Under UK GAAP, deferred taxation is only accounted for to the extent
          that it is probable that a liability or asset will arise in the
          foreseeable future. Under US GAAP, deferred taxation is accounted for
          on all timing differences, and a valuation allowance is established
          in respect of those deferred taxation assets where it is more likely
          than not that some portion will not be realised.

   (b)    Dividends

          Under UK GAAP, dividends proposed are provided for in the year in
          respect of which they are recommended by the Boards of Directors.
          Under US GAAP, such dividends are provided for in the period they are
          declared by the Boards of Directors.

   (c)    Current assets and liabilities

          Current assets under UK GAAP include amounts which fall due after
          more than one year. Under US GAAP such assets would be reclassified
          as non-current assets.

   (d)    Combined statement of cash flows

          The Group's combined cash flow statement is prepared in accordance
          with Financial Reporting Standard No 1 (Revised 1996) and presents
          substantially the same information as that required under US GAAP.
          However, there are certain differences in classification of items
          within the cash flow statements and with regard to the definition of
          cash and cash equivalents between UK and US GAAP.

          Cash flows from (i) operating activities; (ii) returns on investments
          and servicing of finance; (iii) taxation; (iv) capital expenditure
          and financial investment; and (v) financing activities are presented
          separately under UK GAAP, However, US GAAP only requires presentation
          of cash flows from three activities; operating, investing and
          financing.

          Cash flows from taxation and returns on investments and servicing of
          finance are, with the exception of dividends paid and interest paid
          but capitalised, included as operating activities under US GAAP. The
          payment of dividends is included under financing activities and
          capitalised interest is included under capital expenditure and
          financial investment for US GAAP purposes.

          Cash and cash equivalents under UK GAAP include bank loans and
          overdrafts repayable within three months from the date of the
          advance. Under US GAAP all short-term borrowings and overdrafts are
          included in financing activities.

             NOTES TO THE COMBINED FINANCIAL STATEMENTS (continued)


   (e)    Stock compensation plans

          Ocean Group operates a number of stock based compensation plans.
          Under UK GAAP, O.I.L. Group has not recognised any cost in respect of
          these plans, since the O.I.L. Group portion of the total Ocean Group
          costs in relation to these plans is immaterial.

          Under US GAAP, the application of Accounting Principles Board Opinion
          No 25 "Accounting for Stock Issued to Employees" results in a charge
          in respect of O.I.L. Group employees which is immaterial and
          accordingly has not been included in the reconciliations of net
          income and invested equity.
