Financial instruments and related disclosures | 42. Financial instruments and related disclosures GSK uses a variety of financial instruments to finance its operations and derivative financial instruments to manage market risks from these operations. These derivatives, principally comprising interest rate swaps, foreign exchange forward contracts and swaps, are used to swap borrowings and liquid assets into currencies required for Group purposes and to manage exposure to financial risks from changes in foreign exchange rates and interest rates. GSK does not hold or issue derivatives for speculative purposes and GSK’s Treasury policies specifically prohibit such activity. All transactions in financial instruments are undertaken to manage the risks arising from underlying business activities. Capital management GSK’s financial strategy supports the Group’s strategic priorities and is regularly reviewed by the Board. GSK manages the capital structure of the Group through an appropriate mix of debt and equity. The capital structure of the Group consists of net debt of £13.2 billion (see Note 31, ‘Net debt’) and total equity, including that provided by non-controlling non-controlling Our long-term credit rating with Standard and Poor’s is A+ (stable outlook) and with Moody’s Investor Services (‘Moody’s’) it is A2 (stable outlook). The Group’s short-term credit ratings are A-1 P-1 Liquidity risk management GSK’s policy is to borrow centrally in order to meet anticipated funding requirements. The strategy is to diversify liquidity sources using a range of facilities and to maintain broad access to financial markets. At 31 December 2017, GSK had £2.8 billion of borrowings repayable within one year and held £3.9 billion of cash and cash equivalents and liquid investments of which £2.5 billion was held centrally. GSK has access to short-term finance under a $10 billion (£7.4 billion) US commercial paper programme; $0.7 billion (£0.5 billion) was in issue at 31 December 2017 (2016 – $1.4 billion). GSK also has £1.9 billion five year committed facilities and $2.5 billion (£1.9 billion) of 364 day committed facilities. The five-year committed facilities were agreed in September 2015 and were extended by one year to 2021 in September 2016. The 364 day committed facilities were agreed in August 2017. These facilities were undrawn at 31 December 2017. GSK considers this level of committed facilities to be adequate, given current liquidity requirements. GSK has a £15 billion European Medium Term Note programme and at 31 December 2017, £9.0 billion of notes were in issue under this programme. The Group also had $9.7 billion (£7.2 billion) of notes in issue at 31 December 2017 under a US shelf registration. GSK’s borrowings mature at dates between 2018 and 2045. The put options owned by minority interest partners in ViiV Healthcare and the Consumer Healthcare JV business are both now exercisable. In reviewing liquidity requirements GSK considers that sufficient financing options are available should the put options be exercised. Market risk Interest rate risk management GSK’s objective is to minimise the effective net interest cost and to balance the mix of debt at fixed and floating interest rates over time. The policy on interest rate risk management limits the amount of floating interest payments to a prescribed percentage of operating profit. Foreign exchange risk management Foreign currency transaction exposures arising on external trade flows are not normally hedged. Foreign currency transaction exposures arising on internal trade flows are selectively hedged. The Group’s objective is to minimise the exposure of overseas operating subsidiaries to transaction risk by matching local currency income with local currency costs where possible. GSK’s internal trading transactions are matched centrally and inter-company payment terms are managed to reduce foreign currency risk. Foreign currency cash flows can be hedged selectively including hedges of the foreign exchange risk arising from acquisitions and disposals of assets. Where possible, GSK manages the cash surpluses or borrowing requirements of subsidiary companies centrally using forward contracts to hedge future repayments back into the originating currency. In order to reduce foreign currency translation exposure, the Group seeks to denominate borrowings in the currencies of our principal assets and cash flows. These are primarily denominated in US Dollars, Euros and Sterling. Borrowings can be swapped into other currencies as required. Borrowings denominated in, or swapped into, foreign currencies that match investments in overseas Group assets may be treated as a hedge against the relevant assets. Forward contracts in major currencies are also used to reduce exposure to the Group’s investment in overseas assets (see ‘Net investment hedges’ section of this note for further details). Credit risk The Group considers its maximum credit risk at 31 December 2017 to be £9,988 million (31 December 2016 – £11,002 million) which is the total of the Group’s financial assets with the exception of ’Other investments’ (comprising equity investments) which bear equity risk rather than credit risk. See page 216 for details on the Group’s total financial assets. At 31 December 2017, GSK’s greatest concentrations of credit risk were £0.5 billion with Citibank (A/A1) and £0.5 billion with one US wholesaler (BBB+/Baa2) (2016 – £0.9 billion with Citibank (A/A1)). Treasury-related credit risk GSK sets global counterparty limits for each of GSK’s banking and investment counterparties based on long-term credit ratings from Moody’s and Standard and Poor’s. Usage of these limits is monitored daily. GSK actively manages its exposure to credit risk, reducing surplus cash balances wherever possible. This is part of GSK’s strategy to regionalise cash management and to concentrate cash centrally as much as possible. The table below sets out the credit exposure to counterparties by rating for liquid investments, cash and cash equivalents and derivatives. The gross asset position on each derivative contract is considered for the purpose of this table, although, under ISDA agreements, the amount at risk is the net position with each counterparty. Table (e) on page 220 sets out the Group’s financial assets and liabilities on an offset basis. At 31 December 2017, £45 million of cash is categorised as held with unrated or sub-investment BBB-/Baa3) BBB-/ 2017 AAA/Aaa AA/Aa A/A BBB/Baa BB+/Ba1 Total Bank balances and deposits — 423 1,167 80 45 1,715 US Treasury and Treasury repo only money market funds 1,715 — — — — 1,715 Liquidity funds 403 — — — — 403 Government securities — 77 — 1 — 78 3rd party financial derivatives — 26 42 — — 68 Total 2,118 526 1,209 81 45 3,979 2016 AAA/Aaa AA/Aa A/A BBB/Baa BB+/Ba1 Total Bank balances and deposits — 542 1,560 388 93 2,583 US Treasury and Treasury repo only money market funds 2,248 — — — — 2,248 Liquidity funds 66 — — — — 66 Government securities — 85 — 4 — 89 3rd party financial derivatives — 70 86 — — 156 Total 2,314 697 1,646 392 93 5,142 Credit ratings are assigned by Standard and Poor’s and Moody’s respectively. Where the opinions of the two rating agencies differ, GSK assigns the lower rating of the two to the counterparty. Where local rating agency or Fitch data is the only source available, the ratings are converted to global ratings equivalent to those of Standard and Poor’s or Moody’s using published conversion tables. GSK’s centrally managed cash reserves amounted to £2.5 billion at 31 December 2017, all available within three months. This includes £1.7 billion centrally managed cash held by ViiV Healthcare, a 78.3% owned subsidiary. The Group has invested centrally managed liquid assets in bank deposits, Aaa/AAA rated US Treasury and Treasury repo only money market funds and Aaa/AAA rated liquidity funds. Wholesale and retail credit risk Outside the US, no customer accounts for more than 5% of the Group’s trade receivables balance. In the US, in line with other pharmaceutical companies, the Group sells its products through a small number of wholesalers in addition to hospitals, pharmacies, physicians and other groups. Sales to the three largest wholesalers amounted to approximately 83% of the sales of the US Pharmaceuticals and Vaccines businesses in 2017. At 31 December 2017, the Group had trade receivables due from these three wholesalers totalling £1,265 million (2016 – £1,323 million). The Group is exposed to a concentration of credit risk in respect of these wholesalers such that, if one or more of them encounters financial difficulty, it could materially and adversely affect the Group’s financial results. The Group’s credit risk monitoring activities relating to these wholesalers include a review of their quarterly financial information and Standard & Poor’s credit ratings, development of GSK internal risk ratings, and establishment and periodic review of credit limits. However, the Group believes there is no further credit risk provision required in excess of the normal provision for bad and doubtful debts (see Note 24, ‘Trade and other receivables’). Fair value of financial assets and liabilities The table on page 216 presents the carrying amounts and the fair values of the Group’s financial assets and liabilities at 31 December 2017 and 31 December 2016. The fair values of the financial assets and liabilities are included at the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The following methods and assumptions were used to estimate the fair values: • Cash and cash equivalents – approximates to the carrying amount • Liquid investments – based on quoted market prices or calculated based on observable inputs in the case of marketable securities; based on principal amounts in the case of non-marketable • Other investments – equity investments traded in an active market determined by reference to the relevant stock exchange quoted bid price; other equity investments determined by reference to the current market value of similar instruments or by reference to the discounted cash flows of the underlying net assets • Short-term loans, overdrafts and commercial paper – approximates to the carrying amount because of the short maturity of these instruments • Long-term loans – based on quoted market prices in the case of European and US Medium term notes and other fixed rate borrowings (a Level 1 fair value measurement); approximates to the carrying amount in the case of floating rate bank loans and other loans • Contingent consideration for business acquisitions – based on present values of expected future cash flows • Interest rate swaps, foreign exchange forward contracts, swaps and options – based on the present value of contractual cash flows or option valuation models using market sourced data (exchange rates or interest rates) at the balance sheet date • Receivables and payables, including put options – approximates to the carrying amount • Company-owned life insurance policies – based on cash surrender value • Lease obligations – approximates to the carrying amount. Fair value of investments in GSK shares At 31 December 2017, the Employee Share Ownership Plan (ESOP) Trusts held GSK shares with a carrying value of £400 million (2016 – £286 million) and a fair value of £882 million (2016 – £667 million) based on quoted market price. The shares are held by the ESOP Trusts to satisfy future exercises of options and awards under employee incentive schemes. In 2017, the carrying value, which is the lower of cost or expected proceeds, of these shares has been recognised as a deduction from other reserves. At 31 December 2017, GSK held Treasury shares at a cost of £5,800 million (2016 – £6,451 million) which has been deducted from retained earnings. 2017 2016 Notes Carrying Fair Carrying Fair Available-for-sale Liquid investments (Government bonds) a 78 78 89 89 Other investments a 918 918 985 985 Loans and receivables: Cash and cash equivalents 3,833 3,833 4,897 4,897 Trade and other receivables and Other non-current b 5,495 5,495 5,499 5,499 Financial assets at fair value through profit or loss: Trade and other receivables and Other non-current a,b 506 506 361 361 Derivatives designated as at fair value through profit or loss a,d,e 5 5 23 23 Derivatives classified as held for trading under IAS 39 a,d,e 71 71 133 133 Total financial assets 10,906 10,906 11,987 11,987 Financial liabilities measured at amortised cost: Borrowings excluding obligations under finance leases: – bonds in a designated hedging relationship d (4,315 ) (4,405 ) (3,189 ) (3,335 ) – other bonds (11,894 ) (14,743 ) (14,111 ) (16,996 ) – bank loans and overdrafts (236 ) (236 ) (332 ) (332 ) – commercial paper (529 ) (529 ) (1,094 ) (1,094 ) – other borrowings (49 ) (49 ) — — Total borrowings excluding obligations under finance leases f (17,023 ) (19,962 ) (18,726 ) (21,757 ) Obligations under finance leases (66 ) (66 ) (64 ) (64 ) Total borrowings (17,089 ) (20,028 ) (18,790 ) (21,821 ) Trade and other payables, Other provisions and certain Other non-current c (20,325 ) (20,325 ) (18,713 ) (18,713 ) Financial liabilities at fair value through profit or loss: Contingent consideration liabilities a,c (6,172 ) (6,172 ) (5,896 ) (5,896 ) Derivatives designated as at fair value through profit or loss a,d,e (26 ) (26 ) (92 ) (92 ) Derivatives classified as held for trading under IAS 39 a,d,e (48 ) (48 ) (102 ) (102 ) Total financial liabilities (43,660 ) (46,599 ) (43,593 ) (46,624 ) Net financial assets and financial liabilities (32,754 ) (35,693 ) (31,606 ) (34,637 ) The valuation methodology used to measure fair value in the above table is described and categorised on page 215. Trade and other receivables, Other non-current non-current (a) Financial instruments held at fair value The following tables categorise the Group’s financial assets and liabilities held at fair value by the valuation methodology applied in determining their fair value. Where possible, quoted prices in active markets are used (Level 1). Where such prices are not available, the asset or liability is classified as Level 2, provided all significant inputs to the valuation model used are based on observable market data. If one or more of the significant inputs to the valuation model is not based on observable market data, the instrument is classified as Level 3. Other investments classified as Level 3 in the tables below comprise equity investments in unlisted entities with which the Group has entered into research collaborations and also investments in emerging life science companies.

Losses of £971 million (2016 – £2,283 million) were reported in Other operating income and income of £1 million (2016 – £nil) was recorded in Finance income. £909 million (2016 – £2,162 million) arose from remeasurement of the contingent consideration payable for the acquisition of the former Shionogi-ViiV Healthcare joint venture and £53 million (2016 – £152 million) arose from remeasurement of the contingent consideration payable on the acquisition in 2015 of the Novartis Vaccines business. Net gains of £22 million (2016 – £29 million) attributable to Level 3 financial instruments reported in Other comprehensive income as Fair value movements on available-for-sale Financial liabilities measured using Level 3 valuation methods at 31 December included £5,542 million (2016 – £5,304 million) in respect of contingent consideration payable for the acquisition in 2012 of the former Shionogi-ViiV Healthcare joint venture. This consideration is expected to be paid over a number of years and will vary in line with the future performance of specified products and movements in certain foreign currencies. They also included £584 million (2016 – £545 million) in respect of contingent consideration for the acquisition in 2015 of the Novartis Vaccines business. This consideration is expected to be paid over a number of years and will vary in line with the future performance of specified products, the achievement of certain milestone targets and movements in certain foreign currencies. Sensitivity analysis on these balances is provided in Note 39, ‘Contingent consideration liabilities’.

All the derivative liabilities and £68 million (2016 – £156 million) of the derivative assets have a maturity of less than one year. 2017 Fair value 2016 Assets Liabilities Assets Liabilities Net investment hedges – Foreign exchange contracts (principal amount – £6,333 million (2016 – £5,362 million)) 5 (25 ) 18 (92 ) Cash flow hedges – Foreign exchange contracts (principal amount – £38 million (2016 – £170 million)) — (1 ) 5 — Derivatives designated as at fair value through profit or loss 5 (26 ) 23 (92 ) Foreign exchange contracts (principal amount – £14,449 million (2016 – £14,943 million)) 62 (47 ) 133 (99 ) Embedded and other derivatives 9 (1 ) — (3 ) Derivatives classified as held for trading under IAS 39 71 (48 ) 133 (102 ) Total derivative instruments 76 (74 ) 156 (194 ) Foreign exchange contracts classified as held for trading under IAS 39 The principal amount on foreign exchange contracts is the absolute total of outstanding positions at the balance sheet date. The Group’s foreign exchange contracts are for periods of 12 months or less. At 31 December 2017, the Group held outstanding foreign exchange contracts with a net asset fair value of £15 million (£62 million asset less £47 million liability). At 31 December 2016, the fair value was £34 million net asset (£133 million asset less £99 million liability). The overall decrease in the net asset fair value has been due to the weakening of Sterling against the Euro in 2017 and the strengthening of Sterling against the US Dollar which has impacted on the portion of the hedging portfolio that is not in a designated accounting hedge. Fair value movements are taken to the income statement in the period to offset the exchange gains and losses on the related underlying balances. Fair value hedges At 31 December 2017, the Group had no designated fair value hedges. Net investment hedges During the year, certain foreign exchange contracts were designated as net investment hedges in respect of the foreign currency translation risk arising on consolidation of the Group’s net investment in its European (Euro) foreign operations as shown in the table above. The carrying value of bonds on page 216 includes £4,315 million (2016 – £3,189 million) that are designated as hedging instruments in net investment hedges. Cash flow hedges During 2017, the Group entered into forward foreign exchange contracts which have been designated as cash flow hedges. These are hedging the foreign exchange exposure arising on Euro denominated coupon payments relating to notes issued under the Group’s European Medium Term Note programme and a number of highly probable forecast transactions denominated in US Dollars. In addition, the Group carries a balance in reserves that arose from pre-hedging (e) Offsetting of financial assets and liabilities Financial assets and liabilities are offset and the net amount reported in the balance sheet where there is a legally enforceable right to offset the recognised amounts, and there is an intention to settle on a net basis or realise the asset and settle the liability simultaneously. There are also arrangements that do not meet the criteria for offsetting but still allow for the related amounts to be offset in certain circumstances, such as bankruptcy or the termination of a contract. The following tables set out the financial assets and liabilities that are offset, or subject to enforceable master netting arrangements and other similar agreements but not offset, as at 31 December 2017 and 31 December 2016. The column ‘Net amount’ shows the impact on the Group’s balance sheet if all offset rights were exercised. At 31 December 2017 Gross Financial Net financial £m Related Net Financial assets Trade and other receivables 5,191 (1 ) 5,190 (31 ) 5,159 Derivative financial instruments 76 — 76 (64 ) 12 Financial liabilities Trade and other payables (20,130 ) 1 (20,129 ) 31 (20,098 ) Derivative financial instruments (74 ) — (74 ) 64 (10 ) At 31 December 2016 Gross Financial Net financial Related Net Financial assets Trade and other receivables 5,136 (1 ) 5,135 (29 ) 5,106 Derivative financial instruments 156 — 156 (117 ) 39 Financial liabilities Trade and other payables (11,042 ) 1 (11,041 ) 29 (11,012 ) Derivative financial instruments (194 ) — (194 ) 117 (77 ) Amounts which do not meet the criteria for offsetting on the balance sheet but could be settled net in certain circumstances principally relate to derivative transactions under ISDA (International Swaps and Derivatives Association) agreements where each party has the option to settle amounts on a net basis in the event of default of the other party. As there is presently not a legally enforceable right of offset, these amounts have not been offset in the balance sheet, but have been presented separately in the table above. (f) Debt interest rate repricing table The following table sets out the exposure of the Group to interest rates on debt, including commercial paper. The maturity analysis of fixed rate debt is stated by contractual maturity and of floating rate debt by interest rate repricing dates. For the purpose of this table, debt is defined as all classes of borrowings other than obligations under finance leases. 2017 2016 Total debt £m Total Floating and fixed rate debt less than one year (2,802 ) (4,106 ) Between one and two years (1,340 ) (2,216 ) Between two and three years (1,076 ) (1,277 ) Between three and four years (16 ) — Between four and five years (1,475 ) — Between five and ten years (3,664 ) (4,082 ) Greater than ten years (6,650 ) (7,045 ) Total (17,023 ) (18,726 ) Original issuance profile: Fixed rate interest (16,209 ) (17,342 ) Floating rate interest (765 ) (1,381 ) Total interest bearing (16,974 ) (18,723 ) Non-interest (49 ) (3 ) (17,023 ) (18,726 ) (g) Sensitivity analysis The tables below illustrate the estimated impact on the income statement and equity as a result of hypothetical market movements in foreign exchange and interest rates in relation to the Group’s financial instruments. The range of variables chosen for the sensitivity analysis reflects management’s view of changes which are reasonably possible over a one-year Foreign exchange sensitivity The Group operates internationally and is primarily exposed to foreign exchange risk in relation to Sterling against movements in US Dollar, Euro and Japanese Yen. Foreign exchange risk arises from the translation of financial assets and liabilities which are not in the functional currency of the entity that holds them. Based on the Group’s net financial assets and liabilities as at 31 December, a weakening and strengthening of Sterling against these currencies, with all other variables held constant, is illustrated in the tables below. The tables exclude financial instruments that expose the Group to foreign exchange risk where this risk is fully hedged with another financial instrument. 2017 2016 Income statement impact of non-functional Increase/(decrease) in £m Increase/(decrease) in 10 cent appreciation of the US Dollar 76 77 10 cent appreciation of the Euro (5 ) 18 10 yen appreciation of the Yen 9 1 2017 2016 Income statement impact of non-functional Increase/(decrease) in £m Increase/(decrease) in 10 cent depreciation of the US Dollar (66 ) (66 ) 10 cent depreciation of the Euro 4 (16 ) 10 yen depreciation of the Yen (8 ) (1 ) The equity impact, shown below, for foreign exchange sensitivity relates to derivative and non-derivative 2017 2016 Equity impact of non-functional Increase/(decrease) £m Increase/(decrease) 10 cent appreciation of the US Dollar 1 11 10 cent appreciation of the Euro (1,028 ) (795 ) 2017 2016 Equity impact of non-functional Increase/(decrease) £m Increase/(decrease) 10 cent depreciation of the US Dollar (1 ) (10 ) 10 cent depreciation of the Euro 861 670 The tables below present the Group’s sensitivity to a weakening and strengthening of Sterling against the relevant currency based on the composition of net debt as shown in Note 31 adjusted for the effects of foreign exchange derivatives that are not part of net debt but affect future foreign currency cash flows. 2017 2016 Impact of foreign exchange movements on net debt (Increase)/decrease in net debt £m (Increase)/decrease 10 cent appreciation of the US Dollar (637 ) (746 ) 10 cent appreciation of the Euro 197 190 10 yen appreciation of the Yen (4 ) (11 ) 2017 2016 Impact of foreign exchange movements on net debt (Increase)/decrease in net debt £m (Increase)/decrease 10 cent depreciation of the US Dollar 549 634 10 cent depreciation of the Euro (165 ) (160 ) 10 yen depreciation of the Yen 4 10 Interest rate sensitivity The Group is exposed to interest rate risk on its outstanding borrowings and investments where any changes in interest rates will affect future cash flows or the fair values of financial instruments. The majority of debt is issued at fixed interest rates and changes in the floating rates of interest do not significantly affect the Group’s net interest charge, although the majority of cash and liquid investments earn floating rates of interest. The table below hypothetically shows the Group’s sensitivity to changes in interest rates in relation to Sterling, US Dollar and Euro floating rate financial assets and liabilities. If the interest rates applicable to floating rate financial assets and liabilities were to have increased by 1% (100 basis points), and assuming other variables had remained constant, it is estimated that the Group’s finance income for 2017 would have increased by approximately £5 million (2016 – £3 million increase). A 1% (100 basis points) movement in interest rates is not deemed to have a material effect on equity. 2017 2016 Income statement impact of interest rate movements Increase/(decrease) £m Increase/(decrease) 1% (100 basis points) increase in Sterling interest rates 24 3 1% (100 basis points) increase in US Dollar interest rates (24 ) (3 ) 1% (100 basis points) increase in Euro interest rates 5 3 (h) Contractual cash flows for non-derivative The following tables provides an analysis of the anticipated contractual cash flows including interest payable for the Group’s non-derivative non-cancellable Obligations Finance charge on Trade payables and Interest on under finance obligations under other liabilities not Debt debt leases finance leases in net debt Total At 31 December 2017 £m £m £m £m £m £m Due in less than one year (2,802 ) (555 ) (23 ) (2 ) (21,521 ) (24,903 ) Between one and two years (1,344 ) (497 ) (27 ) (2 ) (853 ) (2,723 ) Between two and three years (1,078 ) (488 ) (8 ) (1 ) (813 ) (2,388 ) Between three and four years (16 ) (488 ) (2 ) (1 ) (784 ) (1,291 ) Between four and five years (1,483 ) (468 ) (1 ) (1 ) (752 ) (2,705 ) Between five and ten years (3,694 ) (2,018 ) (5 ) (5 ) (3,609 ) (9,331 ) Greater than ten years (6,720 ) (3,996 ) — — (1,471 ) (12,187 ) Gross contractual cash flows (17,137 ) (8,510 ) (66 ) (12 ) (29,803 ) (55,528 ) Finance charge on Trade payables and Obligations obligations other Interest on under finance under finance liabilities not Debt debt leases leases in net debt Total At 31 December 2016 £m £m £m £m £m £m Due in less than one year (4,108 ) (705 ) (23 ) (2 ) (11,621 ) (16,459 ) Between one and two years (2,218 ) (566 ) (22 ) (1 ) (8,784 ) (11,591 ) Between two and three years (1,282 ) (503 ) (12 ) — (961 ) (2,758 ) Between three and four years — (496 ) (7 ) — (786 ) (1,289 ) Between four and five years — (496 ) — — (705 ) (1,201 ) Between five and ten years (4,117 ) (2,122 ) — — (3,474 ) (9,713 ) Greater than ten years (7,124 ) (4,522 ) — — (3,135 ) (14,781 ) Gross contractual cash flows (18,849 ) (9,410 ) (64 ) (3 ) (29,466 ) (57,792 ) The increase in contractual cash flows for non-derivative Anticipated contractual cash flows for the repayment of debt and debt interest have decreased by £2.6 billion over the year due to a reduction in the issuance of commercial paper and favourable exchange rate movements on US Dollar denominated debt.
