No further appropriations have been made in respect of this scheme. On 31 December 2001, a total of 800,072 shares in International Power plc were held by the Trustee on behalf of 3,201 present and former employees of the Group. At the EGM of the Company held on 29 September 2000, shareholders approved the establishment of the Restricted Share Plan. Participants in the Plan are full-time Executive Directors who are required to devote substantially the whole of their working time to the duties of the Company and any subsidiaries of the Company (as designated by the Directors). Only Peter Giller participates in this Plan. The Company acquired 677,564 shares in International Power plc for a consideration of £1.7 million in the nine months ended 31 December 2000. On 2 October 2001, 225,854 shares were released to Peter Giller, the balance of shares remaining in trust. At demerger, the Board of the Company established the Demerger Share Plan to provide an incentive to those employees (other than Executive Directors) who were remaining in continuous full-time employment with the Company. On 3 October 2000, the Board made conditional awards of 288,359 shares to 181 employees of the Company. No specific purchases of shares have been made in respect of this Plan to date as the Company is utilising the balance of shares unallocated from two former employee share plans that ceased operation at demerger (the total number of unallocated shares at 31 December 2001 was 269,923), to meet the vesting of conditional awards under the Demerger Share Plan. Conditional awards will normally vest to participants on the third anniversary of the demerger. During the year, a total of 9,002 shares have been released to individuals ceasing employment with the Company in accordance with their entitlement under the rules of the Demerger Share Plan.

Financial instruments comprise net debt (see note 27) together with other instruments deemed to be financial instruments including long-term debtors and creditors and provisions for liabilities and charges. Short-term debtors and creditors have been excluded from all the following disclosures other than the currency risk disclosures as relevant. The fair value of short-term debtors and creditors approximates to the carrying value because of their short maturity. In accordance with FRS 13 deferred tax has been excluded from the following disclosures. The interest rate profile of the financial liabilities of the Group as at 31 December 2001 was:  | | | | | | | | 31 December 2001 | | | | | | 31 December 2000 | | | | | | | | | | Total | | Floating rate | | Fixed rate | | Total | | Floating rate | | Fixed rate | | | | | | financial | | financial | | | | financial | | financial | | | | | | liabilities | | liabilities | | | | liabilities | | liabilities | | Currency | | £m | | £m | | £m | | £m | | £m | | £m | | | Sterling | | 12 | | 12 | | - | | 47 | | 47 | | - | | | US dollar | | 1,050 | | 318 | | 732 | | 545 | | 286 | | 259 | | | Australian dollar | | 474 | | 104 | | 370 | | 573 | | 144 | | 429 | | | Czech koruna | | 65 | | 12 | | 53 | | 24 | | 10 | | 14 | | | Others | | 18 | | ° | | 18 | | - | | - | | - | | | Total | | 1,619 | | 446 | | 1,173 | | 1,189 | | 487 | | 702 | | | All the Group's creditors falling due within one year (other than bank and other borrowings) are excluded from the above tables either due to the exclusion of short-term items or because they do not meet the definition of financial liabilities. There are no material financial liabilities on which interest is not paid. The effect of the Group interest swaps was to classify £370 million of floating rate Australian dollar borrowings as fixed rate, £443 million of floating rate US dollar borrowings as fixed rate and £15 million of variable rate Czech koruna borrowings as fixed rate, in the above table. In line with policy on translation exposure hedging, the Group has entered into cross currency swaps from sterling into Czech koruna of £38 million. In addition to the above, the Group's provisions are considered to be floating rate financial liabilities as, in establishing the provisions, the cash flows have been discounted. The floating rate financial liabilities comprise bank borrowings bearing interest rates fixed in advance for various time periods up to 12 months by reference to LIBOR for that time period. The figures in the tables below take into account interest rate and currency swaps used to manage the interest rate and currency profile of financial liabilities and financial assets.  | | | | | 31 December 2001 | | | | 31 December 2000 | | | | Fixed rate financial liabilities | | Fixed rate financial liabilities | | | | | | | | | | Weighted | | Weighted | | Weighted | | Weighted | | | | average | | average period | | average | | average period | | | | interest rate | | for which | | interest rate | | for which | | | | | | rate is fixed | | | | rate is fixed | | Currency | | % | | Years | | % | | Years | | | Sterling | | - | | - | | - | | - | | | US dollar | | 6.01 | | 4 | | 4.94 | | 4 | | | Australian dollar | | 9.86 | | 5 | | 7.28 | | 6 | | | Czech koruna | | 13.02 | | 1 | | 13.02 | | 2 | | | Others | | 7.25 | | 16 | | - | | - | | | Weighted average | | 7.38 | | 4 | | 6.53 | | 5 | | | The Group had the following financial assets as at 31 December 2001:  | | | | 31 December 2001 | | 31 December 2000 | | | | | | | | | | Total | | Floating rate | | Fixed rate | | Total | | Floating rate | | Fixed rate | | | | | | financial | | financial | | | | financial | | financial | | | | | | assets | | assets | | | | assets | | assets | | Currency | | £m | | £m | | £m | | £m | | £m | | £m | | | Sterling | | 71 | | 71 | | - | | 18 | | 18 | | - | | | US dollar | | 138 | | 138 | | - | | 15 | | 15 | | - | | | Euro | | 398 | | 398 | | - | | - | | - | | - | | | Australian dollar | | 71 | | 71 | | - | | 47 | | 47 | | - | | | Czech koruna | | 7 | | 7 | | - | | 27 | | 26 | | 1 | | | Others | | 6 | | 6 | | - | | - | | - | | - | | | Total | | 691 | | 691 | | - | | 107 | | 106 | | 1 | | | The cash deposits comprise deposits placed in money market funds, and a variety of investments with maturities up to three months. All investments are in publicly quoted stocks or treasury instruments. Letters of credit totalling £250 million are supported on a cash collateral basis at 31 December 2001. As explained under Net debt and capital structure of the Operating and financial review and prospects, the Group's objectives in managing the currency exposures arising during the normal course of business (in other words, its structural currency exposures) is to fully hedge all known contractual currency exposures, where possible. As at 31 December 2001 and 31 December 2000, these exposures were not considered to be material. Currency exposures comprise the monetary assets and monetary liabilities of the Group that are not denominated in the operating (or 'functional') currency of the operating unit involved, other than certain non-sterling borrowings treated as hedges of net investments in overseas operations. For major currencies, it is not Group policy to hedge currency translation through forward contracts or currency swaps. The maturity profile of the Group's financial liabilities, other than short-term creditors and accruals, was as follows:  | | | | 31 December | | 31 December | | | | 2001 | | 2000 | | | | £m | | £m | | | In one year or less, or on demand | | 127 | | 88 | | | In more than one year but not more than two years | | 390 | | 319 | | | In more than two years but not more than five years | | 749 | | 298 | | | In more than five years | | 353 | | 484 | | | Total | | 1,619 | | 1,189 | | | The Group has substantial borrowing facilities available to it. The committed facilities available at 31 December 2001 in respect of which all conditions precedent have been met at that date amount to £1,502 million. The undrawn element of these were as follows: Uncommitted facilities available at 31 December 2001 were:  | | | | 31 December 2001 | | 31 December 2000 | | | | | | | | | | Total | | Drawn | | Undrawn | | Total | | Drawn | | Undrawn | | Facility | | £m | | £m | | £m | | £m | | £m | | £m | | | Bank borrowing and overdraft facilities | | 44 | | - | | 44 | | 56 | | - | | 56 | | | Pelican Point working capital facility | | 3 | | - | | 3 | | 4 | | - | | 4 | | | | | 47 | | - | | 47 | | 60 | | - | | 60 | | | Bank borrowing facilities are normally reaffirmed by the banks annually although they can theoretically be withdrawn at any time. These facilities include a £43 million letter of credit facility which becomes committed for any letters of credit that have been drawn. At 31 December 2001, £30 million of letters of credit had been drawn from this facility. Set out below is a comparison by category of book values and fair values of all the Group's financial assets and liabilities as at 31 December 2001.  | | | | 31 December 2001 | | 31 December 2000 | | | | | | | | Primary financial instruments held or issued to finance the Group's operations | | Book | | Fair | | Book | | Fair | | | value | | value | | value | | value | | | £m | | £m | | £m | | £m | | | Short-term borrowings and current portion of long-term borrowings | | (127) | | (127) | | (88) | | (88) | | | Long-term borrowings | | (1,492) | | (1,497) | | (1,101) | | (1,103) | | | Cash deposits and current asset investments | | 691 | | 691 | | 107 | | 107 | | |  | | | | Year ended | | Nine months ended | | | | 31 December 2001 | | 31 December 2000 | | | | | | | | Derivative financial instruments held to manage the interest rate, currency profile and exposure to energy prices | | Notional | | Carrying | | Fair | | Gain/ | | Gross | | Gross | | Gross | | Gross | | | book value | | value | | Value | | (loss) | | gain | | (loss) | | gain | | (loss) | | | £m | | £m | | £m | | £m | | £m | | £m | | £m | | £m | | | , | | | | | | | | | | | | | | | | | Interest rate swaps and similar instruments | | 829 | | - | | (17) | | (17) | | - | | (17) | | - | | (31) | | | Currency swaps | | (38) | | - | | (2) | | (2) | | - | | (2) | | 3 | | (1) | | | Forward foreign currency contracts | | (74) | | - | | (2) | | (2) | | 1 | | (3) | | 1 | | (3) | | | Energy derivatives | | - | | - | | 6 | | 6 | | 17 | | (11) | | - | | (2) | | | In addition to the above, debtors include £1 million (31 December 2000: £nil) in respect of the fair value of energy derivatives arising from proprietary trading. The methods and assumptions used to estimate fair values of financial instruments are as follows: i) For investments of up to three months, trade debtors, other debtors and prepayments, trade creditors, other current liabilities, longterm and short-term borrowings, the book value approximates to fair value because of their short maturity. ii) The fair value of investments maturing after three months has been estimated using quoted market prices. iii) The fair value of long-term borrowings and interest rate swaps has been calculated using market prices when available or the net present value of future cash flows arising. iv) The fair value of the Group's forward exchange contracts, foreign currency swaps and foreign currency options has been calculated using the market rates in effect at the balance sheet dates. v) The fair value of energy derivatives is measured using value at risk and other methodologies that provide a consistent measure of risk across diverse energy products. Within the above fair values, only the financial assets and liabilities have been marked-to-market as defined by the requirements of the accounting standard. As explained under Net debt and capital structure of the Operating and financial review and prospects, the Group's policy is to hedge the following exposures: i) Interest rate risk - using interest rate swaps, options and forward rate agreements. ii) Structural and transactional currency exposures - using currency borrowings, forward foreign currency contracts, currency options and swaps. iii) Currency exposures on future expected sales - using currency swaps, forward foreign currency contracts, currency options and swaps. iv) Energy price fluctuations - using physical hedges through the operation of energy supply and trading activities together with financial products. Gains and losses on instruments used for hedging are not recognised until the exposure that is being hedged is itself recognised. Unrecognised gains and losses on instruments used for hedging, and the movements therein, are as follows:  | | | Debt | | Foreign | | Energy | | Total net | | | | | | exchange | | derivatives | | gain/(loss) | | | | £m | | £m | | £m | | £m | | | Unrecognised gains and (losses) on hedges at 1 January 2001 | | (31) | | - | | (2) | | (33) | | | Gains and (losses) arising in previous periods that were recognised in the year ended 31 December 2001 | | (22) | | 2 | | - | | (20) | | | Gains and (losses) arising in the year ended 31 December 2001 that were not recognised in the year | | (8) | | (2) | | 8 | | (2) | | | Unrecognised gains and (losses) on hedges at 31 December 2001 | | (17) | | (4) | | 6 | | (15) | | | Of which: | | Gains and (losses) expected to be recognised in the year ended 31 December 2002 | | - | | (3) | | 9 | | 6 | | | Gains and (losses) expected to be recognised in the year ended 31 December 2003 or later | | (17) | | (1) | | (3) | | (21) | | | The hedging of structural currency exposures associated with foreign currency net investments are recognised in the balance sheet.
