Notes to editors

3i Infrastructure plc is a Jersey-incorporated, closed-ended investment company that invests in infrastructure businesses and assets and is regulated by the Jersey Financial Services Commission. The Company is building a diversified portfolio of infrastructure investments across the globe, with a focus on Europe and India. As of 31 March 2013, 3i Infrastructure had a portfolio of 14 assets valued at £919 million, and net assets of £1,103 million. The Company listed on the London Stock Exchange in March 2007, raising £703 million in an initial public offering and a further £115 million in a subsequent placing and open offer in July 2008, and is a constituent of the FTSE 250 index.

3i Investments plc, a wholly-owned subsidiary of 3i Group plc, is authorised and regulated in the UK by the Financial Services Authority and acts as Investment Adviser to 3i Infrastructure plc.

Our portfolio

The information above is presented according to the investment basis of preparation and not according to IFRS.

Chairman's statement

This was a successful year for the Company. Growth in Net Asset Value ('NAV') was strong and the portfolio continued to generate good levels of income which covered our dividend. We also delivered a realisation from the portfolio at a good uplift to carrying value.

The Company faced some difficulties too. In my outlook statement last year I said that conditions for investment were challenging and markets were volatile. Those conditions persisted throughout this financial year, which led to a difficult environment for investment and continued volatility in returns from the portfolio in India.

In its annual review of strategy this year the Board focused on the outlook for the infrastructure market, on opportunities to build on the existing strengths of the business and portfolio and reflected upon the changes to the market since the Company's financial targets were set back in 2007. As a result, we are rebalancing our investment strategy in favour of less volatile investments, reducing our exposure to higher risk hybrid investments in India over time, and therefore updating our return objective to an annual measure of 10% total return per annum. We are also increasing our dividend objective to 5.5% of opening NAV. We believe these objectives reflect the continuing opportunity to develop further our diversified portfolio of infrastructure investments, which deliver long-term yield with the potential for capital growth.

Performance

Looking at the financial performance in more detail, the total comprehensive income attributable to the equity holders of the parent (the "total return") on a consolidated IFRS basis was £92 million in the year to 31 March 2013. On an investment basis, which the Board also uses to monitor performance, the total return was £89 million, or 8.6% on shareholders' equity. This return was delivered through the strong performance of the Company's European portfolio, which generated both good income and value growth in the year. The European portfolio's strong returns were partly offset by the weaker performance of the investments in the 3i India Infrastructure Fund, which continued to be negatively affected by adverse macroeconomic and market conditions.

Dividend

Reflecting the strong income generation, the Board proposes a final dividend of 3.52p per share which, added to the interim dividend of 2.97p per share, exceeds the 5% dividend objective for this year and represents 5.5% of opening NAV, in line with our new objective for future years.

Investment activity

Investment levels were low this year, with 3i Infrastructure completing two new investments, totalling £17 million. The Company invested £12 million in the Dalmore Capital Fund, which is building a portfolio of secondary PFI investments in the UK. In addition, £5 million was invested in Supreme Roads, a portfolio of road BOT projects in India, through the 3i India Infrastructure Fund (the "India Fund"). In addition to our new investments, significant progress has been made on the Thameslink XLT transaction, which is approaching financial close.

As outlined in the Investment Adviser's review, there continues to be competition for infrastructure assets, as investors are attracted to investments that can provide stable income in a low interest rate environment. Price points, as a result, have remained high. Against this backdrop, the Board and Investment Adviser have retained their investment and pricing discipline.

In keeping with our strategy of selling investments at attractive prices relative to our valuations and of crystallising value for shareholders, the Company sold its investment in Alpha Schools in March to a wholly-owned subsidiary of HICL Infrastructure Company Limited. The sale generated gross proceeds of £21.2 million and the Board was pleased to deliver a strong premium to the opening value of £18.5 million through the sale. There is a detailed case study on the Alpha Schools divestment in the Investment Adviser's review. 3i Infrastructure also received proceeds of £6.9 million as a result of loan repayments from Eversholt and Elgin.

Strategic update

In its annual strategic update, the Board assessed the Company's investment strategy and objectives in the context of developments in the infrastructure investment market, as well as of the performance of its portfolio. It concluded that the Company would make no new investments in India and would focus its future investment activity in core infrastructure and PPP in developed markets, in particular in the UK and continental Europe. Over time, as the investments in the India Fund are gradually realised, the portfolio will rebalance in favour of less volatile investments in core infrastructure and primary social infrastructure in Europe.

As a result of the review of our strategy and the rebalancing of risk and reward across the portfolio, the Board has decided to update the Company's return objective to an annual measure of 10% NAV growth, of which 5.5% is to be delivered through an annual dividend. The move to an annual total return target, rather than a long-term target based on full investment, recognises that 3i Infrastructure is a mature company, whose performance target should be an annual measure against an absolute return objective incorporating its funding requirements, rather than a long-term objective based on full investment.

The review validated the investment strategy and approach adopted thus far, which has delivered a strong performance across the Company's core and social infrastructure portfolios. The European portfolio has consistently delivered capital and income returns in line with or, more often, ahead of expectations, confirming the benefits of diversification within the portfolio. This portfolio provides a solid bedrock for the future. Core infrastructure markets will offer significant opportunity for skilled investors, which we believe the Investment Adviser is well placed to access.

We also believe that the PPP market will offer attractive investment opportunities, strategically aligned to our principles of delivering income and potential for capital growth. Investment in social and energy infrastructure is at the heart of the Europe-wide political agenda to stimulate economic growth. Private sector funding is a key element in determining the success of these ambitions, as resource-constrained governments seek to open up essential infrastructure through PPP-style transactions.

The Company, through the Investment Adviser, is well positioned to access opportunities across these markets with its leading track record of returns from core and PPP/PFI infrastructure investments, including primary projects such as Alpha Schools and Alma Mater.

Macroeconomic, market and regulatory conditions in India have been more challenging than initially expected when the Company committed to the India Fund in 2007. This investment has not, to date, delivered the premium risk adjusted returns that were expected and has brought unwelcome volatility to overall portfolio performance. On this basis, the Board has decided that the Company will make no further new investment in India or emerging markets, lowering overall portfolio return volatility.

The key elements of our strategic update are outlined in the Strategic update section below.

Cash balances and liquidity

As at 31 March 2013, 3i Infrastructure had cash balances of £179 million, of which £31 million will be used for the payment of the proposed final dividend, £3 million to new investment in Dalmore, £60 million to the Thameslink transaction and £25 million for any residual cash calls by the 3i India Infrastructure Fund, although it is unlikely that this amount will be drawn down in full.

With a significant portion of the cash balances invested or committed, the Board looked to secure the Company's liquidity in the medium term. On 2 May 2013, the Company entered into a new, £200 million, three-year revolving credit facility with a syndicate of five major banks. This new facility replaces the £200 million facility entered into in November 2010, which was due to expire in November 2013, on improved terms. As with the previous facility, the Board intends to use this liquidity as a bridge to equity, to be refinanced through equity issuance in due course.

Corporate governance and Board

There were a number of changes to the Board during the year. Charlotte Valeur served on the Board until 31 March 2013. Paul Masterton was appointed as non-Executive Director with effect from 4 April 2013. I would like to express my gratitude to Charlotte for her valuable contribution as a Director, and welcome Paul to the Board. Paul, a Jersey resident, has spent the majority of his career in the printing and communications industry, holding various appointments in the UK, the US and Asia.

In May, Florence Pierre and Paul Waller indicated that they wished to resign from the Board at the Company's AGM, to be held on 9 July 2013. I would like to thank them also for their valuable contribution. Paul Waller will be replaced by Ben Loomes as the 3i Group nominated Director of the Company. Ben will stand for election at the Company's AGM in July 2013.

The Board aims to uphold the highest standards of corporate governance and, in the year under review, complied with all applicable provisions of the UK Corporate Governance Code. At the last Annual General Meeting, held on 10 July 2012, shareholders approved the re-election of all Directors to the Board.

Investment Adviser and exclusivity arrangements

The Board has a Management Engagement Committee (comprising all independent Board members), which is tasked with managing the Company's relations with the Investment Adviser, including carrying out the annual evaluation of the Investment Adviser. This evaluation concluded that, based on good performance, the continued appointment of the Investment Adviser is in the interest of shareholders.

In November 2012, the Company and the Investment Adviser agreed an amendment to the Investment Advisory Agreement. This further extended the amount covered by the Agreement by £47 million, to cover the cash balances available for investment at 30 September 2012.

Outlook

Looking forward, the Board is confident that the Company has a strategy in place to deliver a 10% annual return and a dividend of 5.5% of opening NAV in the current climate, with reduced volatility. As the investments in the India Fund are gradually realised, we will redeploy our capital in core infrastructure and PPP, our key areas of strength, where we have built a market-leading track record of performance.

Strategic update

Key elements

Our investment strategy and approach, as well as our return objectives, dated back to our IPO in 2007. Since then, our portfolio has developed, as have the markets in which we operate.

In its strategic update this year, the Board assessed the Company's strategy and objectives in light of these changes. The review took a number of factors into consideration.

Updating our financial objectives

As a result of this strategic review and of the rebalancing of risk and reward across the portfolio, we updated our financial objectives. This also reflects the composition of our existing portfolio and the market environment in which we operate.

Our updated objectives assume:

§ A blended portfolio return, which reflects the returns from our existing European portfolio and a re-balancing of the portfolio away from India, in favour of core infrastructure and PPP in developed markets;

§ An evolution of the market environment in which we operate, where projected returns from new infrastructure investments are lower than in 2007, as are interest rates; and

§ Greater portfolio income generation, as the non-yielding India Fund investments are sold and proceeds re-deployed in core infrastructure and PPP projects.

The revised total return objective also accommodates costs and incorporates our funding strategy, with an element of dilution from holding cash balances for future investment.

Building on the bedrock of our portfolio and through the rigorous focus on core infrastructure and PPP, we can deliver these objectives with reduced volatility in the years to come.

Investment Adviser's review

About the Investment Adviser

3i Investments plc ("3i Investments"), a wholly-owned subsidiary of 3i Group plc ("3i Group"), acts as the investment adviser (the "Investment Adviser") to the Company through its infrastructure investment team (the "investment advisory team").

The investment advisory team provides advice to the Company on the origination and completion of new investments, on the management of the portfolio and on realisations, as well as on funding requirements. The investment advisory team is managed as a separate business line within 3i Group and operates from hubs in London and India. All investment professionals have significant experience investing in infrastructure assets. The investment advisory team can also draw on 3i Group's network of investment professionals to originate infrastructure investment opportunities.

3i Group was among the subscribers to 3i Infrastructure's Initial Public Offering and subsequent Placing and Open Offer and owns 34% of the equity in the Company.

The infrastructure asset class - key characteristics

Infrastructure businesses generally have a strong market position, often operating within regulatory frameworks, or with revenues underpinned by strong, long-term contracts. They can be described as "essential", either because they are fundamental to economic activity and economic growth, such as utilities or transport infrastructure, or because they support important social functions, such as education or healthcare facilities. Key features include:

§ strong market position underpinning revenues (eg long-term contracts, quasi monopolies);

§ capital-intensive;

§ some degree of inflation linkage;

§ low volatility through economic cycles;

§ predictable, income-oriented returns when operational; and

§ potential for capital growth.

Infrastructure assets typically have only a low correlation with other asset classes, including listed equities, real estate and fixed income. The quality and predictability of cash flows tend to result in attractive distributions to shareholders.

Investment strategy

To achieve 3i Infrastructure's return objectives, the Investment Adviser aims to build a portfolio that delivers a balance of both yield and an element of capital growth, by focusing on the PPP and core infrastructure markets.

The infrastructure asset class offers the opportunity to diversify investments across the risk/return spectrum. As shown in the table above, we believe it can be sub-divided into three main categories: social, core and hybrid infrastructure.

Returns and yields from these categories typically range between 7% and 15% or more, depending, among other things, on the risks associated with the investments and on their state of development (eg under construction versus fully operational).

Core infrastructure investing

Core infrastructure companies are dynamic businesses which own their asset base.

Investing in core infrastructure businesses is therefore more complex and requires a broader set of skills, including:

§ a sound operational understandingof the business and of how to drive long-term value through investment in the asset base, the management of costs and the incentivisation of management teams;

§ in-depth knowledge of the marketand regulatory dynamics; and

§ the ability to deliver an efficient financing structure.

An engaged portfolio management approach is key in driving value from core infrastructure investments over the long term. Before committing to any investment, we develop a comprehensive understanding of the company, of the markets in which it operates, its competitive dynamics and the relevant regulatory environment.

3i Infrastructure has permanent capital and intends to drive value from its investments over long-term hold periods. Therefore, after making each investment, we engage with the management team at board level, as well as more informally, to develop strategies that support:

§ investment in the asset base to promote growth over the long term;

§ continued improvements in operational performance;

§ disciplined cash management to drive yield for shareholders;

§ efficient capital structures that can evolve according to market contingencies and business needs; and

§ alignment of interest between management and shareholders, ensuring management focus on the long-term development of the business, rather than on short-term goals.

The Investment Adviser has a strong track record in core infrastructure investing, having delivered robust returns from the Company's investments in Anglian Water Group, Oystercatcher, Eversholt Rail Group and, most recently, Elenia.

PPP investing

Primary PPP investing involves investing in projects at the start of the concession rather than secondary acquisitions in operational projects. This usually requires a financial investor to:

§ form a consortium with a primary developer to put together a bid;

§ support the consortium through a bidding process, drawing on relevant financial, legal and commercial advice;

§ underpin a share of the bid costs;

§ shape the funding plans required for the project;

§ negotiate the contractual structurewith the procuring authority; and

§ oversee the construction of the facilities or assets to be provided under the contract within the timescale and to the standards agreed with the procuring authority, taking construction and ramp-up risk.

Primary investing involves higher risks than secondary investing, where financial investors buy stakes in projects that have completed their construction phase, are operational and with contractual and financing structures already agreed. In return for accepting these risks and providing the necessary resources, investment returns from primary projects are generally higher than secondary returns and can be quantified towards the upper end

of the 7%-12% return bracket for social infrastructure.

Contracts are often structured so as to ensure that consortia receive payments from procuring authorities before the facilities or assets are fully operational.

Primary investing therefore requires specialist skills, a strong understanding of the market and good relationships with primary developers.

The Investment Adviser has a strong track record in primary investing, as demonstrated by the successful investments in Alma Mater, Alpha Schools and some projects within the I2 portfolio, all of which have now been realised successfully. Primary investments of this type have allowed the Investment Adviser to crystallise the benefits of supporting projects through their construction phase and selling them into a very competitive secondary market when fully operational. The divestment of Alpha Schools in March 2013, is described in the case study below.

The Company's proposed investment in the Thameslink Rolling Stock Procurement Programme has many of the characteristics of primary PPP. 3i Infrastructure, with Siemens and Innisfree, its Thameslink XLT consortium partners, submitted a bid to the Department for Transport ("DfT") for the delivery, maintenance and financing of around 1,200 vehicles, as part of a broader upgrade programme for the Thameslink line. The consortium was named preferred bidder in June 2011 and has subsequently been negotiating complex contractual and financing structures with the DfT and a group of banks.

Secondary PPP investing involves secondary acquisitions of projects that are already operational. Due to the lower risks involved, returns from this type of investment tend to be lower than returns from primary projects. We have a strong track record of successful investing in secondary projects.

In October 2012, the Company announced that it had made a commitment of £15 million to the Dalmore Capital Fund ("Dalmore"), which specialises in investing in the UK secondary PFI market. Dalmore is managed by Dalmore Capital Limited, which is run by key members of the team that managed I2, which generated an IRR for the Company of 23.8% on full exit. The investment in Dalmore builds on our strong track record in secondary PFI and provides us with access to the specialist investment skills of the team at Dalmore Capital in this market.

Divestment case study - Alpha Schools

About Alpha Schools

Alpha Schools (Highland) Limited ("Alpha Schools") is a concession company under a 30-year PFI contract (commenced in 2006) to build, operate and maintain 11 new schools on 10 sites in the Highland region of Scotland. Alpha Schools receives RPIX-linked payments from the Highlands Council to cover services and building maintenance. The construction of the schools commenced in 2006 and was completed in 2011.

The investment in Alpha Schools was part of the initial portfolio seeded into 3i Infrastructure at its IPO in 2007. The PFI investments in that initial portfolio provided balanced exposure to both early-stage (Alpha Schools, Alma Mater) and operational projects (Octagon, a majority of the projects within I2). Investments in early-stage PFI projects typically generate returns that are higher compared to the returns generated by operational PFI projects, reflecting the higher construction and execution risks involved. Both early-stage and operational PFI investments provide portfolios with lower risk, index-linked cash flows and robust yields.

Through the Investment Adviser, the Company managed its investment in Alpha Schools through the construction phase and through ramp-up, achieving a robust track record of operational performance when the facilities became fully operational.

The realisation

On 25 March 2013, 3i Infrastructure announced it had sold its 50% holding in Alpha Schools to a wholly-owned subsidiary of HICL Infrastructure Company Limited ("HICL"), which already owned the balance of the investment. The sale of the investment, which 3i Infrastructure held through a subsidiary undertaking, generated gross proceeds of £21.2 million, representing a premium to the opening valuation of £18.5 million and to the cost of £9.1 million.

Value creation from primary investing

While 3i Infrastructure, with its permanent capital, is set up to hold investments over the long term, it will sell assets where attractive offers crystallise the value created in an investment over the period of ownership, or where there is a strong market for that particular investment. Both these conditions were met in the case of Alpha Schools. HICL's offer crystallised the value growth generated over the period of ownership, at a considerable uplift to the cost and the opening value of the investment, against the backdrop of a competitive market for secondary PFI investments. Having generated good returns from the investment through the construction phase and through ramp-up to successful operation, 3i Infrastructure sold its investment once it had achieved a track record of stable returns, which was reflected in a lower discount rate.

Hybrid infrastructure investing

The Company currently invests in hybrid infrastructure through its US$250 million commitment to the US$1.2 billion India Fund, managed by the Investment Adviser through a dedicated team in India. The India Fund reached the end of its investment period in November 2012 and will make no new investments. In this post-investment phase, the India Fund will focus on realising its portfolio over time and this will reduce the Company's exposure to India. The Company's remaining commitment to this fund is limited to 15% of the original US$250 million commitment, or US$37.5 million and is, in practice, unlikely to be drawn in full.

The rationale for this commitment, made in 2007, was that it would provide exposure to a diversified portfolio of early-stage infrastructure investments in India, expected to deliver gross returns of around 20% through the fund's life but with a higher risk profile (construction risk and country/geopolitical risk).

The investment in the India Fund has not delivered the capital growth that the Board and Investment Adviser expected when the commitment was made. While the operational development of the investments in the India Fund has proceeded broadly according to plan, a number of macroeconomic, market and political factors have weighed on their performance. These factors are outlined in the 3i India Infrastructure Fund review.

At 31 March 2013, the Fund was valued at 0.8x cost in US dollar terms and 1.0x cost in rupee terms. Rather than enhancing overall returns, the investment in the India Fund has introduced an element of volatility to overall portfolio valuations, despite the strong performance of its social and core infrastructure portfolios. In recognition of the higher than expected risks involved in hybrid infrastructure investing (and specifically in infrastructure investing in India), the Board established that 3i Infrastructure will make no further investments in India (beyond the current commitment to the India Fund).

Investment track record

The Investment Adviser has implemented its strategy rigorously since the Company was set up. As a result, 3i Infrastructure now has a portfolio that has provided:

§ significant income supporting the consistent delivery of the Company's annual dividend objective;

§ strong capital profits from realisations; and

§ an element of capital growth underpinning the 16% gross IRR shown in Table 1.

The value created through this robust investment performance has been crystallised in a number of instances through well managed realisations. While the Company is structured to hold investments over the long term, it will sell assets on an opportunistic basis, where compelling offers generate shareholder value, as was the case for Alma Mater in 2008, I2 in 2009, the junior debt portfolio in 2011-12 and Alpha Schools in 2013.

Tables 1 and 2 illustrate the investment track record since 3i Infrastructure's inception. In particular:

§ the core and social infrastructure portfolios have generated strong returns, in line with, or ahead of expectations;

§ the return is underpinned by substantial cash generation in the form of income or capital profits;

§ most investments return a significant proportion of their cost through income in a relatively short period of time;

§ where investments have been sold, they have generated good uplifts over cost, and an overall IRR of 19.3%; and

§ the valuation of the India Fund has been volatile.

Note:The calculation of the IRR (Internal Rate of Return) uses cash flows generated from the investments to calculate the annualised effective compound rate of return. The calculation uses: (i) total cost (original cost plus any further investment); (ii) proceeds for investments that have been sold, or from capital returns; and (iii) closing value for investments that have not been sold.

As shown in Table 2, from investment of £1,092 million, since the Company's inception the portfolio has returned cash income of £296 million and realised proceeds of £428 million.

Market and opportunities

Conditions for investment

Allocations to the infrastructure asset class have continued to grow as many investors increasingly seek opportunities that deliver a high level of income. This trend has intensified as yields in some other asset classes remain compressed in a persistently low interest rate environment.

This has resulted in significant demand for infrastructure assets from specialist financial investors, as well as direct investors such as large pension funds and sovereign wealth funds.

There were a number of major transactions in regulated utilities across Europe last year, including OpenGrid, Wales and West Gas and Veolia Water, but generally market activity in core infrastructure has been muted. The deals that were completed continued to be supported by the availability of capital markets and bank debt for strong infrastructure businesses, even as liquidity in other sectors remained relatively constrained.

As demand for infrastructure assets increases, price points have risen. This trend has been noticeable across the infrastructure market, with projected returns available from secondary PFI investments and from core infrastructure investments in stable economies reduced.

The broader market environment remains volatile. Economies in Europe are struggling to recover, as the sovereign debt crisis endures, the availability of credit remains constrained and a number of countries, particularly in the euro periphery, continue to face significant macroeconomic and political headwinds.

In this environment, we have remained disciplined investors and have avoided overbidding in competitive processes, focusing on a narrower set of opportunities in the UK and Northern Europe. As a result, investment activity has been lower than in previous years.

The market opportunity in core infrastructure

The themes driving the market opportunity in core infrastructure are broadly unchanged compared to last year. Disposals from corporates and financial institutions have continued to provide the majority of investment opportunities. In particular, utilities as well as oil and gas majors are selling distribution and downstream assets to focus on generation and upstream activities, while banks and other financial institutions are selling assets or portfolios to comply with capital adequacy regulations.

Opportunities in core infrastructure are also likely to derive, in due course, from the sale of assets by specialist financial investors. Some infrastructure funds, nearing the end of their investment periods, will need to realise investments to return capital or prove valuations.

The market opportunity in PPP

Investment in social infrastructure is at the heart of the Europe-wide political agenda to create growth and private sector funding is a critical element in the success of these ambitions. Over time, we expect resource-constrained governments throughout Europe to increasingly privatise or open up essential infrastructure through PPP-style transactions. There are now over 1,000 closed PPP projects across Europe, with a combined equity value of around £10 billion, spanning critical sectors providing essential services including schools and hospitals, as well as prisons, roads, light rail, water treatment plants, military support equipment, government accommodation facilities and energy projects.

Well over £1 billion has been raised by specialist investors over the past three years in investment vehicles focused on this type of investment. Investors continue to have much appetite for the long-term, low-risk and income oriented returns offered by investments in PPP projects. Investments in primary projects, in particular, have proven increasingly attractive in light of the premium returns promised by this type of investment.

The UK's primary project market has slowed down since the Conservative-Liberal Democrat coalition government came into power in 2010, although a new PFI programme focused on new school and healthcare projects was recently launched and the Government has announced details of its proposed PF2 model for PPP. Other European governments have developed similar PPP models to access private sector capital and outsourcing expertise, particularly in France, Belgium and the Netherlands, with smaller programmes also in place in Germany and Scandinavia.

India

Infrastructure deal volumes have fallen in India as a result of lower GDP growth rates, a growing fiscal deficit, currency volatility and persistently high inflation and high interest rates. While the fundamental case for infrastructure development (and private involvement in this) remains unaltered, there are challenges in this market at present.

The India Fund reached the end of its investment period in November 2012 and 3i Group, which through 3i Investments manages the India Fund, suspended new fundraising in this market. It is likely that the Company's remaining commitment to the India Fund will remain largely undrawn. The team's focus will be on preparing the India Fund's investments for sale in a challenging market.

Outlook

The infrastructure market continues to offer attractive opportunities. We are seeing good investments in both core and social infrastructure, our key areas of focus and we expect to be investing further over the next year.

As part of the XLT consortium, we are making significant progress with the DfT on the Thameslink Rolling Stock Procurement Programme.

We are also currently focusing on a number of opportunities in the northern European core infrastructure market. While returns available from infrastructure investing in our core markets remain under pressure, we will continue to seek opportunities where we have a competitive advantage over other bidders, where we can engage at an early stage or leverage market relationships to ensure that portfolio returns are not compromised.

Portfolio

Table 3 below summarises the valuation and movements in the portfolio, as well as the return per investment, for the year to 31 March 2013 on an investment basis. Table 4 below illustrates the distribution of the portfolio by geography, sector and maturity at 31 March 2013. Table 5 illustrates the distribution of the portfolio in the risk/return framework.

1 Includes a £7.2 million negative impact from US$/rupee exchange movements.

2 T2C was sold in the year for a nominal amount.

Movements in portfolio value

As set out in Table 6, the portfolio was valued at £918.7 million at 31 March 2013, compared to £890.8 million at the beginning of the financial year. Total portfolio value growth was £24.7 million in the year, with the strong performance of the European portfolio only partly offset by poor performance in India. Investment of £16.5 million was more than offset by divestment of £25.4 million. Foreign exchange movements increased portfolio value by £12.1 million. However, net of the impact of the hedging programme, the effect of foreign exchange movements on total return was minimal.

Investment

3i Infrastructure invested a total of £16.5 million in the year.

On 12 October 2012, the Company announced that it had made a commitment of £15.0 million to the Dalmore Capital Fund ("Dalmore"), £10.0 million of which was drawn at that date to fund Dalmore's £89.5 million acquisition of a 49.9% stake in a portfolio of UK PFI assets from Interserve plc. A further £1.9 million of this commitment was drawn by Dalmore in January 2013 to increase its stake in two of the projects in that portfolio. On 28 March 2013, Dalmore admitted two new limited partners and the Company received a return of £0.3 million of its initial investment, taking the net investment to £11.6 million.

Dalmore is managed by Dalmore Capital Limited ("Dalmore Capital") which is run by key members of the team that managed I2, a secondary PFI fund in which 3i Infrastructure previously held an investment and which generated an IRR for the Company of 23.8% on full exit. The investment in Dalmore builds on the Company's strong track record in social infrastructure and provides it with access to the specialist investment skills of the team at Dalmore Capital in the secondary PFI market.

In addition, at the end of January 2012, the India Fund entered into an agreement to acquire a minority stake in a portfolio of road build-operate-transfer ("BOT") companies of Supreme Infrastructure India Limited. The transaction closed on 3 July 2012, with the India Fund investing US$35.9 million. 3i Infrastructure invested US$7.5 million (£4.9 million) through the India Fund as its share in this transaction.

Divestment

On 25 March 2013, 3i Infrastructure sold its 50% holding in Alpha Schools (Highland) Holdings Limited ("Alpha Schools") to a wholly-owned subsidiary of HICL Infrastructure Company Limited (which already owned the balance of the investment). The sale of the investment in Alpha Schools, which was held through a subsidiary undertaking, generated gross proceeds of £21.2 million, representing a significant premium to the opening value of £18.5 million. Alpha Schools, a concession company under a PFI contract to build, operate and maintain 11 new schools in Scotland, was part of the initial portfolio seeded into the Company at its IPO in 2007.

As previously reported, the Company received proceeds of £6.6 million from Eversholt Rail Group and of £0.3 million from Elgin following the partial repayment of their shareholder loans, bringing total divestment proceeds received in the period to £25.4 million.

During the year, 3i Infrastructure's investment in Thermal Conversion Compound ("T2C") was sold for a nominal amount, generating no proceeds for the Company. 3i Infrastructure invested in T2C, a special purpose company established to build, operate and maintain a waste-to-energy plant on an industrial park near Frankfurt, in 2007. A provision was taken against the value of T2C in March 2010, due principally to significant delays in the construction of the plant. The investment had remained valued at nil since then.

Unrealised value movement

Overall, the portfolio generated a total unrealised value gain of £24.7 million in the year to 31 March 2013 (2012: £7.0 million). The European portfolio achieved strong returns in the year, increasing in value by £51.0 million. This positive performance was partially offset by poor performance in India, with the valuation of the Company's holding in the India Fund declining by £26.3 million over the same period.

Core portfolio

The core portfolio generated a good value uplift in the year, with unrealised value growth of £49.1 million, driven by the continued strong operational performance of the underlying investments, the impact on value of the successful refinancing of the Oystercatcher acquisition debt and reflecting the strong market for European core infrastructure assets. Value increases were partly offset by income receipts.

The valuation of Anglian Water Group (£230.6 million at the end of March 2013, compared to £209.4 million a year earlier) benefited from a number of positive factors, including the end of drought conditions following a period of intense rainfall, the successful raising of new debt at attractive rates, the satisfactory outcome of negotiations with Ofwat on potential licence changes and the sale of Morrison Facilities Services to Mears. AWG is performing in line with its regulatory settlement, and is making good progress in the implementation of its wide-ranging efficiency and capital expenditure programmes. In light of the strong valuations being achieved in transactions in the UK water sector, the discount rate used to value the Company's investment in AWG was reduced since September 2012, as described later in this statement.

Elenia (formerly Lakeside Network Investments) was valued at £205.5 million at 31 March 2013 compared to £201.0 million a year earlier, including foreign exchange gains of £3.9 million. Elenia completed its post-acquisition corporate reorganisation process in January 2013, which allowed it to pay a dividend. 3i Infrastructure's share of this dividend amounted to £20.6 million in this financial year.

Eversholt was valued at £153.6 million at the end of March 2013, which after a partial loan repayment of £6.6 million is up from £154.2 million a year earlier. The valuation benefited from Eversholt's continued strong operational performance, which was balanced by distributions of income. While delays in the refranchising process introduced an element of uncertainty for the industry, the DfT announced a fresh start for the refranchising process at the end of March 2013 (see Eversholt investment review).

The valuation of Oystercatcher (£141.4 million, compared to £118.2 million a year earlier) reflects a value uplift of £21.3 million and foreign exchange gains of £1.9 million. The value gain reflects a reduction in the discount rate used to value the investment following the successful refinancing of the acquisition debt facility, as the discount rate had previously been increased. The three terminals continue to perform well, in line with our expectations.

PFI portfolio

The PFI portfolio achieved unrealised value growth of £1.9 million in the period (2012: £4.9 million). RPI-driven value increases were offset by income distributions of £7.7 million. Dalmore, the Company's most recent social infrastructure investment, performed well in the period of ownership.

3i India Infrastructure Fund

The valuation of the Company's investment in the 3i India Infrastructure Fund declined from £114.2 million at the end of March 2012 to £99.1 million at 31 March 2013, after new investment of £4.9 million. This movement was driven principally by a significant reduction in the valuation of Adani Power Limited, following a 40% decline in its share price over the year. The valuation of the power sector assets in the portfolio declined in the year, due to factors including the availability and pricing of fuel and the terms of power purchase agreements with State Electricity Boards. In addition, Soma Enterprise faced construction challenges in project execution and constraints on working capital, principally due to delays in obtaining approvals from the relevant authorities.

Foreign exchange impact

As shown in Table 7, the reported foreign exchange gain on investments of £12.1 million reduced to a net £1.6 million gain after other foreign exchange related movements, including the impact of the foreign exchange hedging programme.

The Indian rupee depreciated marginally against sterling in the year, resulting in net foreign exchange losses of £0.9 million for the India Fund. The Board monitors both the rupee exposure and the cost/benefit of hedging that exposure on a regular basis.

The euro appreciated by 1.5% against sterling during the year, but the resulting foreign exchange gains were partially offset through the foreign exchange hedging programme undertaken to provide mitigation from movements in that exchange rate, resulting in a net positive impact of only £2.5 million.

Overall, the net impact for the year was a foreign exchange gain of £1.6 million (2012: £16.3 million loss).

1 Contained within Unrealised profits/(losses) on revaluation of investments in Table 9.

Underlying asset performance

The fully operational investments held by the Company delivered a steady performance during the year. Earnings before interest, tax, depreciation and amortisation ("EBITDA") for these investments increased by 2.8% on a like-for-like basis relative to the prior year. EBITDA for the European investments increased by 3.4% on the prior year. Specifically, AWG, Eversholt and Oystercatcher saw year-on-year increases of 2.1%, 2.8% and 8.4% respectively.

The 2.8% overall figure is calculated on a weighted average basis and the investments included in this analysis are those that have been operational and held by the Company for one year or more: AWG, Eversholt, Oystercatcher, Elgin (underlying project companies) and Octagon and, within the 3i India Infrastructure Fund, Adani Power, Krishnapatnam Port, Soma Enterprise, GVK Energy and KMC Roads.

Summary of valuation methodology

Investment valuations are calculated at the half year and at the financial year end by the Investment Adviser and then reviewed and approved by the Board. Investments are reported at the Directors' estimate of fair value at the reporting date.

The valuation principles used are based on International Private Equity and Venture Capital valuation guidelines, generally using a discounted cash flow ("DCF") methodology (except where a market quote is available), which the Board considers to be the most appropriate valuation methodology for unquoted infrastructure equity investments.

Where the DCF methodology is used, the resulting valuation is checked against other valuation benchmarks relevant to the particular investment, including for example:

§ earnings multiples;

§ recent transactions;

§ quoted market comparables; and

§ regulated asset base multiples.

Discounted cash flow and discount rates

As at 31 March 2013, 97.5% of the portfolio was valued on a DCF basis. The weighted average discount rate applied at that date was 12.0% (March 2012: 12.6%), deriving from a range of 8.2% (for an operational PFI asset) to 19.0% (for a project within the 3i India Infrastructure Fund). Table 8 shows the movement in the weighted average discount rate applied to the portfolio at the end of each six-month period since the Company's inception.

The discount rate applied to each investment is reviewed at each valuation date. The rate selected reflects the risk inherent in the business, taking into account sustained movements in the "risk-free" rates of return in the relevant country and appropriate risk premia. Risk-free rates (equating to 10/30-year government bond yields) in our relevant markets have remained flat since the September 2012 valuation and, as such, this did not drive changes to the discount rates applied at 31 March 2013.

Our assessment of risk premia and current market pricing, however, resulted in the following changes to discount rates being applied at the end of the year:

AWG

The discount rate used to value AWG was reduced to reflect: (i) the valuations achieved in recent transactions in the UK water sector (eg Sutton and East Surrey Water); (ii) the sale of Morrison Facilities Services, valued at a higher discount rate compared to the core water and wastewater business; (iii) the Company's continued ability to refinance its debt in the market at attractive rates, as reflected in the continued narrowing of the spread between AWG bond yields and UK gilts; and (iv) the reduced uncertainty in relation to the regulatory licences.

Oystercatcher

The discount rate used to value Oystercatcher was reduced to reflect a de-risking of the investment following the successful refinancing of the acquisition debt facility in March 2013. The discount rate to value Oystercatcher had been increased in March 2012 due to the approaching refinancing.

India

The discount rates applied to value projects across the India Fund's portfolio, based on their stage of development, remained broadly unchanged. The discount rates used to value some individual projects within KMC Roads were reduced, as development milestones were reached. In addition, the discount rate used to value Krishnapatnam Port was reduced slightly to reflect greater confidence in cargo volumes. These changes had no material impact on the overall discount rate applied across the India Fund.

Dalmore Capital Fund and 3i India Infrastructure Fund

The Company's investment in Dalmore and in the India Fund was valued as the Company's share of net assets held by those funds. Within the India Fund valuation, Adani Power, which has been a listed company since August 2009, was valued on a mark-to-market basis using closing bid prices. All other assets were valued on a DCF basis, with the exception of a portion of Soma Enterprise's valuation, which was calculated using earnings multiples, and a small element of the Krishnapatnam Port valuation, derived from the value attributable to a put option, which provides downside valuation protection.

Review of investments

Anglian Water Group

Performance in the year

The value on an IFRS basis is £336.6 million.

Anglian Water Group Limited ("AWG") is the parent company of Anglian Water, the fourth largest water supply and wastewater company in England and Wales as measured by regulatory capital value. The majority of the group's revenue is earned through tariffs regulated by Ofwat and linked to RPI.

The investment is held through 3i Osprey LP, an intermediary limited partnership whose

partners comprise other third parties (including 3i Group, which has a small interest) and which is managed separately by 3i Investments.

Investment rationale

AWG was taken private in 2006 by a group of investors, including Canada Pension Plan, Colonial First State, Industry Funds Management and 3i Group, which "seeded" part of its AWG holding into 3i Infrastructure when it was set up in 2007. The business has strong infrastructure characteristics:

§ a regulated near-monopoly position in its geographical area for the provision of water supply and wastewater treatment;

§ stable and predictable earnings and cash flows through RPI-linked tariffs; and

§ largely predictable operating costs.

In addition, AWG has attractive fundamentals:

§ a strong management team;

§ a relatively modern asset base; and

§ operations in a geographic region with high population growth and relatively low industrial exposure, limiting cyclical correlation.

Achievements in the period of ownership

AWG has flourished under private ownership. It has refocused on its core business, selling Morrison Utilities Services, Morrison Facilities Services and much of its property portfolio. The company has been able to adopt a more efficient capital structure compared to listed peers and to distribute a higher proportion of cash flows to shareholders, resulting in a strong yield. The Regulated Capital Value ("RCV") has grown steadily, underpinned by a comprehensive capital expenditure programme, which has been maintained for the 2010-2015 regulatory period.

A new management incentive scheme was put in place post investment, aligning compensation with long-term value growth, asset quality and customer service rather

than short-term earnings and share price performance. The management now balances long-term planning, for example to respond to the challenges of climate change, with a clear focus on operational efficiency and customer service.

Developments in the year

AWG continued to perform robustly during the year, with its EBITDA increasing by 2.1% year-on-year. Anglian Water is making good progress in the implementation of its current regulatory settlement, with a strong focus on a wide-ranging efficiency programme.

Anglian Water continues to perform well in customer service against its peers, ranking first in Ofwat's Service Incentive Mechanism survey for the year ending 31 March 2013.

The principal issue facing Anglian Water at the end of March 2012 was the drought which followed two unusually dry winters. In response, AWG had started the implementation of incremental capital expenditure to improve further the resilience of water supply and encourage water conservation. The heavy rains seen since April 2012 relieved the drought conditions, but put downward pressure on demand from households and small business customers, and resulted in some flooding. Demand from small businesses was impacted further by the weak economic conditions.

The business has experienced success with its "Keep it Clear" media campaign, highlighting the impact of blockages caused by inappropriate waste being flushed into sewers. The incremental capital expenditure and the impact on demand of record-breaking rainfall resulted in a reduction in the dividend received from AWG this year.

The business continues to implement its cost efficiency and capital spending programmes, performing well against its targets. AWG has been able to raise debt on attractive terms throughout the year, maintaining access to diverse sources of funding.

In November 2012, AWG sold Morrison Facilities Services to Mears for a total consideration of £24 million. This will further reduce the management time dedicated to non-core activities.

Following the publication of its Water White Paper in December 2011, the Government published its draft Water bill in July 2012, setting out a number of changes to the structure of the industry, including the extension of competition for business customers, changes to the abstraction regime to encourage more efficient use of water resources and measures to help the industry manage bad debts. Anglian Water remains proactive across the broad range of issues and will continue to engage widely to ensure that it is well placed to respond to the changes that will ensue. During the year, there was a satisfactory outcome to negotiations with Ofwat regarding its proposed changes to licences. This has enabled management to focus on preparing for the next regulatory review, for which water companies are required to submit draft business plans by the end of 2013.

The Company lowered the discount rate used to value its investment in AWG, reflecting higher comparable valuation benchmarks and supported by AWG's continued robust operational performance and its strong track record of debt raising.

Elenia

Performance in the year

1 Includes an unrealised foreign exchange gain of £3.9 million.

The value on an IFRS basis is £235.5 million.

Elenia owns the second largest electricity distribution network in Finland. Headquartered in Tampere, it serves around 410,000 customers and has a 12% market share. The business is regulated on a four-year cycle, delivering a set return on its regulated asset base.

Elenia Lämpö owns and operates 16 local district heating networks, each with strong market shares in their local areas. It has its headquarters in Hämeenlinna and is the main supplier of heat to the town, with some ancillary electricity production from the Vanaja CHP plant. District heating, which involves the pumping of hot water directly into homes and businesses from central hubs, is not regulated in Finland.

The investment is held through 3i Networks Finland LP, an intermediary limited partnership which is managed separately by 3i Investments.

Investment rationale

3i Infrastructure purchased Elenia from Vattenfall AB in January 2012 in consortium with 3i Group plc, GS Infrastructure Partners and Ilmarinen Mutual Pension Insurance Company.

Elenia has strong infrastructure characteristics:

§ the electricity distribution business operates in a stable and transparent regulatory environment, with regulatory incentives providing opportunities for value-accretive growth;

§ the businesses are profitable and provide inflation linkage. This is likely to support a robust yield to 3i Infrastructure over the long term; and

§ Finland is an attractive market, providing opportunities for consolidation over the medium term.

Developments in the year

Elenia successfully completed the post-acquisition corporate reorganisation in early January 2013. The completion of this process allowed Elenia to distribute its first dividend to shareholders following the acquisition. 3i Infrastructure's share of this distribution was £20.6 million.

Elenia's governance was enhanced through the appointment of new independent chairmen to the boards of each business, as well as through a number of management appointments to further strengthen the executive teams, including a new chief financial officer and a new chief executive for Elenia Lämpö.

The consortium has engaged with the management team of Elenia to update and enhance its capital expenditure plans to improve network reliability.

A number of acquisition opportunities were also examined, with the first bolt-on acquisition, of Asikkalan Voima, completed in August 2012. This is a small distribution company in which Elenia already owned a 50% holding. Elenia purchased the remaining 50% of the shares from Lahti Energia. This acquisition affirms the Company's thesis on consolidation opportunities in the sector.

The Finnish government is seeking to implement legislation aimed at improving reliability of electricity supply in response to outages caused by severe weather conditions in 2011 and 2012. This is a positive development, consistent with Elenia's strategy. We expect detailed proposals from the regulator on revisions to the regulatory regime in the autumn.

Finally, the businesses were rebranded, with the new "Elenia" name successfully launched in May 2012, reinforcing to domestic audiences the separation from Vattenfall.

Eversholt Rail Group

Performance in the year

Eversholt Rail Group ("Eversholt") is one of the three leading rail rolling stock companies in the UK and owns approximately 28% of the current UK passenger train fleet. Its 19 fleets, predominantly weighted towards electric trains, are leased to 11 Train Operating Companies ("TOCs"). Although its primary revenue stream consists of lease payments from TOCs, Eversholt also owns a freight fleet, which accounts for less than 10% of its total value.

The rolling stock companies are not directly regulated, and have instead entered into codes of practice, monitored by the Office of Rail Regulation, under which they agree to work fairly and reasonably with their customers.

Investment rationale

3i Infrastructure, in consortium with Morgan Stanley Infrastructure Partners and STAR Capital Partners, acquired 100% of Eversholt in December 2010.

Eversholt is a well established infrastructure business and fits well with 3i Infrastructure's investment mandate:

§ it has strong market fundamentals, with its fully utilised fleets likely to retain value in the long term, due to strong passenger demand and the high cost of new trains;

§ it has high quality cash flows contracted for the medium term through lease agreements with the TOCs; and

§ it has a defensive fleet portfolio, weighted towards electric trains, with a good operational history, leased to a diversified customer base.

Achievements in the period of ownership

The consortium has strengthened Eversholt's governance through the appointment of several highly experienced non-executive directors to the Irish and UK boards and the establishment of audit and remuneration committees with investor representation. Further executive appointments were made to the Irish and UK businesses to bolster Eversholt's technical, legal and financial resources, positioning it well to manage the significant increase in workload as the pace of rail franchise re-tendering accelerates.

Eversholt's capital structure was de-risked through the issuance of three long-dated public bonds for a total of £1.1 billion, priced on attractive terms and attracting strong demand from public market investors, significantly reducing the ongoing debt servicing costs and refinancing risks.

The consortium has engaged closely with the management team to assess a range of capital investment opportunities, both to add further trains to the overall fleet and to invest in upgrading existing assets to provide better passenger experience and improved reliability, at good value for money for operators.

Developments in the year

Eversholt continued to perform well in the year, with its EBITDA increasing by 2.8% compared to last year. This allowed Eversholt to repay an additional £6.6 million of its shareholder loan. The Company also accrued regular interest payments of £17.8 million.

The cancellation by the Department for Transport ("DfT") of the Intercity West Coast franchise competition and suspension of the wider refranchising programme was a significant disappointment for Eversholt, as it had been heavily involved in supporting bidders for all affected franchises. Eversholt has welcomed the subsequent review of the rail franchising programme led by Richard Brown, which recommended early recommencement of the programme along with reinforcement of the capability and resources of the DfT. In March 2013, the DfT announced a new timetable for future franchises, which staggers the programme over a longer period, necessitating a large number of relatively short franchise extensions/awards. Eversholt is now working proactively with current franchise holders and prospective bidders, as appropriate, to provide the best possible rolling stock solutions for the travelling customer. In particular, the timing for the East Coast franchise competition has been clarified to start in early 2014 and Eversholt has developed innovative proposals to upgrade its existing fleet operating on that franchise.

Market developments have provided a number of asset management opportunities for Eversholt. The company is providing asset management services to the Cross London Trains ("XLT") consortium, the preferred bidder for the Thameslink rolling stock procurement programme.

In December 2012, Eversholt raised £150 million in a private placement with a 20-year maturity, the proceeds of which were used to repay the company's outstanding balance on its capital expenditure facility and to partly repay the senior bank facility. This further extends the maturity profile of Eversholt's debt and demonstrates its ability to access diverse sources of debt funding.

Eversholt's Class 395 trains were used for the Olympic Javelin Train Service, ran by Southeastern Railways to transport passengers from St Pancras Station to the Olympic Park. Approximately 2.4 million passenger journeys were made on this service, or over 90,000 passenger journeys a day throughout the Games.

Oystercatcher

Performance in the year

1 Includes an unrealised foreign exchange gain of £1.9 million.

The value on an IFRS basis is £309.3 million.

Oystercatcher Luxco 2 S.à r.l. ("Oystercatcher") is the holding company through which 3i Infrastructure invested in 45% stakes in three subsidiaries of Oiltanking GmbH ("Oiltanking"), located in the Netherlands, Malta and Singapore. These businesses provide over 3.6 million cubic metres of oil, petroleum and other oil-related storage facilities and associated services to a broad range of clients, including private and state oil companies, refiners, petrochemical companies and traders.

Oiltanking is one of the world's leading independent storage partners for oils, chemicals and gases, operating 75 terminals in 23 countries with a total storage capacity of 20.3 million cubic metres.

Investment rationale

The investment was completed in August 2007. The key elements of the investment case were:

§ strong projected demand for oil and oil-related products;

§ storage capacity is scarce and a key component of the oil and oil product supply chain, resulting in low customer turnover;

§ the three terminals are defensively located in key trading hubs in Amsterdam, Malta and Singapore and have a strong market position;

§ contracts are let on a use-or-pay basis with fixed terms of up to 10 years, often with tariffs linked to local inflation rates, resulting in reliable cash flows; and

§ the transaction allowed 3i Infrastructure to partner with a leading player in the oil storage market, with a strong operational reputation.

Achievements in the period of ownership

The 2007 investment case has largely been confirmed, with the investment performing well. All storage capacity has been fully let throughout the period of investment, and throughput levels have been high. All three terminals have been largely unaffected by the global economic slowdown, even though the "flattening" of the forward curve in recent years has squeezed oil trading margins and increased customers' focus on storage costs during contract renewal negotiations. However, global trade in petroleum products continues to increase, leading to further growth in demand for oil storage.

The Investment Adviser has been actively involved in the assessment of a range of capital expenditure project proposals that have delivered long-term value accretion.

In Singapore, a 160,000 cubic metre expansion project was approved in 2008 to accommodate increasing demand from adjacent refineries and petrochemical industries. This was completed in June 2009, with the capacity let on a use-or-pay basis under a long-term contract to an existing customer.

In Amsterdam, a 42,000 cubic metre expansion project to provide dedicated storage for biodiesel products for a new production facility adjacent to the site was completed in June 2011. This capacity was pre-let on a use-or-pay basis. Several smaller investments were approved to upgrade throughput and customer service. In Malta, investment in a new 13,000 cubic metre tank was approved in 2011, completed in February 2012, and let on a use-or-pay basis to an existing customer.

Since investment, total capacity at the three terminals has increased by 23%, while annual throughput has increased by 18%.

In March 2013, 3i Infrastructure signed the refinancing of the Oystercatcher acquisition debt facility, significantly de-risking its financing structure (see below).

Developments in the year

All three terminals performed ahead of expectations in the year, with their EBITDA up by 8.4% year-on-year.

Market conditions for trading customers have not been as favourable as in previous years, as trading margins remain squeezed by a shallower forward curve, as well as by lower volatility in oil prices. However, the strong market position of all three terminals ensured that customer contracts expiring in 2012 were re-let on improved terms. Throughput levels remained high throughout the year.

In Malta, the construction of an LPG pipeline to transport LPG imports from Oiltanking's jetty to a new storage facility (owned by GASCO Energy Ltd) was completed within budget and the first cargo was received in June 2012. Completion of this pipeline is important, as a smooth supply of LPG is vital to the Maltese economy.

In March 2012, the Company increased the discount rate used to value its holding in Oystercatcher to reflect an increase in the refinancing risk and greater sensitivity to interest rate and exchange rate movements, as the acquisition facility and associated hedging instruments approached maturity in 2014. The refinancing of the acquisition debt facility was completed in March 2013. This allowed a reduction in the discount rate used to value Oystercatcher as at March 2013.

Social Infrastructure

Performance in the year

Elgin

Elgin Infrastructure Limited ("Elgin") is a portfolio of PFI project investments, comprising five schools projects and 11 community healthcare schemes, all of which are fully operational, under concessions of up to 32 years. The portfolio companies receive inflation-linked payments to cover services and buildings maintenance, which are subject to performance deductions for service failures and unavailability. Facilities services are sub-contracted to Robertson Facilities Management (in 15 projects) and Carillion Facilities Management (in one project).

Octagon

Octagon Healthcare Limited ("Octagon") is a concession company under a 35-year PFI contract to build, operate and maintain the Norfolk and Norwich University Hospital. Construction of the hospital was completed in August 2001. Octagon receives RPI-linked payments from the NHS Trust to cover services and buildings maintenance, which are subject to performance deductions for service failures and unavailability. Octagon sub-contracts the provision of facilities services to Serco.

Dalmore

Dalmore Capital Fund ("Dalmore") is a 25-year LP fund managed by Dalmore Capital Limited and investing in the equity and subordinated debt in secondary PFI transactions which are both operational and do not have volume‑based payment regimes. The fund can invest across the social infrastructure sector and targets gross returns of 10% for its investors. At 31 March 2013, Dalmore had total commitments of £170 million. Subsequently, the fund has held a third close, increasing total commitments to £249 million.

Investment rationale

Exposure to social infrastructure through PFI projects provides the Company's portfolio with lower risk, index-linked cash flows. All assets in the Company's PFI portfolio are fully operational and deliver a robust yield.

Achievements in the period of ownership

All assets in the PFI portfolio have performed well through their period of ownership, in line with or ahead of expectations, providing a good return to the Company since inception. This has been due to engaged portfolio management on the part of the Investment Adviser and other shareholders, as well as to more general factors, including higher than expected inflation.

The Investment Adviser generated significant value through the sale of the Company's holdings in Alma Mater, I2 and Alpha Schools at significant uplifts over cost in 2008, 2009 and 2013 respectively, generating an aggregate IRR of 30%.

Developments in the year

All assets in the PFI portfolio performed well operationally during the year, delivering good levels of income.

All 16 projects in the Elgin portfolio are performing in line with the investment case. All service providers are performing well, with no significant operational issues arising at any of the projects during the year.

Octagon continues to perform well financially and operationally and has maintained its strong working relationship with the NHS Trust and with Serco. Serco continues to provide a good level of service to the NHS Trust. In July 2012, the hospital received the top "excellent" rating for standards of cleanliness, food and privacy and dignity, according to the results of an annual PEAT inspection by patient representatives, independent validators and NHS staff. In November 2012, an unannounced inspection of the hospital by the Care Quality Commission found that the hospital met all the essential quality and safety standards inspected. At the end of March 2013, the hospital announced it had been completely clear of MRSA bloodstream infections for more than a year.

In October 2012, the Company announced that it had made a commitment of £15 million to Dalmore, £10 million of which was drawn at that date to fund Dalmore's £89.5 million acquisition of a 49.9% stake in a portfolio of UK PFI assets from Interserve plc. A further £1.9 million of this commitment was drawn by Dalmore in January 2013 to increase its stake in two of the projects in that portfolio.

Dalmore is managed by Dalmore Capital Limited, which is run by key members of the team that managed I2, a secondary PFI fund in which 3i Infrastructure previously held an investment and which generated an IRR for the Company of 23.8% on full exit. The Dalmore Capital team has an excellent track record of originating, acquiring, financing, managing and optimising secondary PFI investments and an extensive network of contacts across the financial institutions and contractors active in the social infrastructure sector.

The investments in Dalmore are performing well and income generation has been in line with expectations.

The Company's investment in Alpha Schools was sold in March 2013.

3i India Infrastructure Fund

Performance in the year

1 Includes a net foreign exchange loss of £0.9 million (sterling/US$ gain of £6.3 million, and US$/rupee loss of £7.2 million).

The 3i India Infrastructure Fund (the "India Fund") is a US$1.2 billion fund which closed in 2008, investing in a diversified portfolio of equity (or equivalent) investments in India, focusing on the port, airport, road and power sectors. 3i Infrastructure committed US$250 million to this fund.

The investment period for the 3i India Infrastructure Fund ended on 30 November 2012 and the Board expects that the Company's remaining commitment will not be substantially drawn.

As at 31 March 2013, the Fund was 73% invested in a portfolio of seven assets:

Krishnapatnam Port Company Limited("Krishnapatnam Port") has a concession to develop, operate and maintain the port of Krishnapatnam in the state of Andhra Pradesh.

KMC Infratech ("KMC Roads") is developing a c. 1,000km portfolio of 10 "build‑operate-transfer" ("BOT") road projects, one of the largest portfolios of its kind in India.

Adani Power Limited ("Adani Power") focuses on the development and operation of power plants and the sale of power generated. With operational capacity of 4,620MW and a further 4,620MW under construction, it is currently the largest independent private power producer in India in terms of operating capacity. Adani Power achieved a successful IPO in August 2009.

GVK Energy is developing a portfolio of power generation projects (4,047MW), diversified by fuel type, stage of development and geography. In addition, GVK Energy is developing two mining projects to supply coal to its own thermal power plants.

Soma Enterprise Limited ("Soma") is one of the leading infrastructure developers in India. Its order book, valued at over US$3.2 billion, focuses mainly on BOT road projects, but also comprises projects in the hydro power, irrigation, railways, power transmission and urban infrastructure sectors.

Ind-Barath Utkal is building a 700MW coal-fired power plant in the state of Orissa.

Supreme Infrastructure BOT Holdings Private Limited ("Supreme Roads"), a subsidiary of Supreme Infrastructure India Limited, a new investment in the year, is building a portfolio of BOT road projects.

Investment rationale

The investment case can be summarised as follows:

§ there is much need for infrastructure investment in India, with the current infrastructure deficit in the country providing opportunity for private investment;

§ the Indian government actively seeks and encourages private investment in infrastructure development and is working to mitigate some of the issues which have affected the sector in recent years;

§ the investment in the India Fund offered 3i Infrastructure exposure to a diversified pool of assets and larger investments than the Company could access on its own account, at no additional cost to the Company; and

§ the India Fund was well positioned, with an established presence in its market through its investment manager.

Achievements in the period of ownership

The India Fund reached the end of its investment period in November 2012 and now has a diversified portfolio of assets in the power, ports and roads sectors, in line with its mandate.

The Company's remaining commitment to the India Fund is limited to 15% of the original US$250 million commitment, or US$37.5 million and, in practice, is unlikely to be drawn in full.

Several of the projects, including Adani Power and Krishnapatnam Port, have increased significantly in size since the India Fund's investment. Despite this, the financial performance and valuation of the India Fund's assets has been affected by a number of market and other external factors, including the depreciation of the Indian rupee. At 31 March 2013, the India Fund's NAV was 0.93x investment cost in sterling terms.

Overall, the Board is satisfied that appropriate action is being taken to manage the performance of the India Fund's assets within the constraints of the macroeconomic and market challenges.

3i Investments, which manages the India Fund, is focused on the realisation of investments over the next two to three years, if market conditions allow.

Developments in the year

Overall, the assets in the India Fund's portfolio have faced significant challenges during the year.

The power assets have continued to be affected by a number of factors, including:

§ the availability of domestic coal and gas: Coal India Limited, the largest coal producer in India, as well as many gas producers, have struggled to match their output to demand from power producers and to deliver supplies to their customers;

§ the pricing of coal: the domestic coal shortage and the depreciation of the rupee against most currencies have affected the price of coal;

§ the inability for electricity producers to pass increased fuel costs through to customers under existing power purchase agreements (PPAs), pending a review from the relevant authorities; and

§ the strain on State Electricity Boards' financial position: SEBs have been financially constrained for a number of years and as a result banks are now reluctant to lend to them. This has constrained their ability to enter into new long-term PPAs with power producers.

In February 2011, the Indian government responded to the issues arising from coal shortages by directing Coal India Limited to sign fuel supply agreements with power plants that have a majority of their offtake tied up in long-term PPAs, with a minimum commitment of 80% of the annual fuel requirement of the plant. However, due to the weak penalties imposed on Coal India Limited for non-compliance, it is expected that supplies are likely to remain short of the contracted quantities, increasing producers' reliance on imports. On the positive side, merchant tariffs have remained relatively buoyant, due to the increasing demand/supply gap, but also due to a reduction in hydro output as a result of below average monsoon rainfall.

These factors continued to have a negative impact on Adani Power's market performance. Its shares declined by 40% during the year. GVK Energy and Ind-Barath Utkal, the India Fund's other power investments, were also affected by these issues, as well as by delays in construction and some increases in construction costs.

After the year end, Adani Power's share price performance was boosted by a decision by power sector regulator (the Central Electricity Regulatory Commission) to compensate Adani Power's Mundra project for the escalation of import fuel costs in the form of increases in tariffs under existing PPAs.

The India Fund's port asset, Krishnapatnam Port, has continued to be affected by an iron ore export ban, which, although now lifted, will subdue exports for some time as production resumes and pent-up domestic demand is satisfied. The company continued to focus on changing its cargo mix and performed well in the year, supported by continued increases in its general cargo and container volumes.

The two smaller road asset portfolios (KMC Roads and Supreme Roads) are making progress, despite some delays relating to land acquisitions and environmental clearances and saw modest value gains during the year. KMC Roads has also faced funding constraints. Soma, the India Fund's largest road investment, faced significant challenges in project execution, due to delays in receipt of approvals from the highways authorities and an escalation in raw material costs, resulting in constraints in working capital.

Macroeconomic conditions in India remain challenging, with slowing growth, currency volatility and persistently high inflation rates continuing to affect the economic outlook.

Financial review

Key performance indicators

1 Opening NAV and opening shareholders' equity are net of the final dividend paid in the prior year and adjusted to take into account any equity issued in the year.

Returns

The commentary in this section analyses the key drivers of the Company's returns according to the investment basis of preparation, as shown in Table 9. The basis of preparation for the investment basis is shown later in this document, along with an analysis of the key differences in accounting treatment to information prepared in accordance with IFRS.

3i Infrastructure generated a total return for the year to 31 March 2013 of £89.1 million, representing an 8.6% return on opening shareholders' equity (2012: £56.0 million, 5.6%). The return was driven principally by portfolio income generation of £72.8 million and by the strong performance of the European assets, but was impacted negatively by the weaker performance of the 3i India Infrastructure Fund ("India Fund").

Capital returns

Realised capital returns

3i Infrastructure generated a realised capital gain of £2.7 million in the year to 31 March 2013, arising from the sale of its holding in Alpha Schools for proceeds of £21.2 million against an opening value of £18.5 million. As described in the case study, the investment in Alpha Schools generated a profit over cost of £12.1 million over the period of ownership.

Unrealised capital returns, including foreign exchange movements

The combined unrealised value movement across the portfolio, including foreign exchange impact, as shown in Table 9, totalled £33.5 million in the year to 31 March 2013.

The European portfolio continued to perform strongly, increasing in value by £51.0 million in the year. This strong performance, however, was offset by the poor performance of several of the assets in the India Fund, which declined in value by £19.1 million. The valuation movements are described in the Movements in portfolio value section.

There were net foreign exchange gains of £1.6 million as sterling depreciated against the euro and appreciated against the Indian rupee, as described in Table 7.

Investment return

Portfolio income

The portfolio generated income of £72.8 million in the year (2012: £73.1 million), of which £46.0 million was through dividends (2012: £41.0 million) and £26.8 million through interest on shareholder loans (2012: £32.1 million, including £1.8 million interest from quoted debt investments).

Elenia paid its first dividend to the Company of £20.6 million in the year (2012: nil) following the completion of its post-acquisition corporate reorganisation.

AWG paid a dividend of £10.7 million and interest of £4.8 million in the year (2012: £15.5 million, £4.7 million). The dividend from AWG was lower than last year, mainly as a result of increased spending on measures to mitigate the effects of extreme weather conditions in early 2012. Further detail is set out in the AWG investment review.

Eversholt generated good cash flows, which have allowed it to pay down £6.6 million of its shareholder loan. The Company also accrued interest of £17.8 million from Eversholt in the year (2012: £20.1 million). Due to the structure of the investment in Eversholt, the income from this asset is received principally as interest on the shareholder loan. The year-on-year decline in the interest accrued is due to the reduction in the amount of the shareholder loan as a result of principal repayments across the last two financial years.

Oystercatcher paid a dividend of £11.2 million in the year (2012: £9.5 million), all of which was received in the first half of the year. No dividend was paid in the second half, as income from the operating companies was not distributed by Oystercatcher, but retained (in addition to some reserves already accumulated in 2012) to cover the costs of refinancing its debt.

The PFI assets generated income of £7.7 million, of which £3.5 million was from dividends and £4.2 million from interest on shareholder loans (2012: £3.0 million, £5.5 million).

Fees payable for transaction costs in relation to deals which did not reach, or have yet to reach, final completion totalled £0.7 million in the year (2012: £1.3 million), with the reduction reflecting the low levels of investment activity during the year.

The costs relating to the refinancing of Oystercatcher were borne by that vehicle

and are reflected in its value movement.

Interest receivable

Interest income from cash and cash equivalents totalled £0.7 million (2012: £1.5 million), the year-on-year decline reflecting higher average cash balances last year and a small reduction in interest rates available on short-term deposits. The Company's cash balances generated interest at an average rate of 0.5% in the year (2012: 0.6%).

Advisory fees, performance fees and other operating and finance costs

During the year to 31 March 2013, the Company incurred advisory fees of £12.9 million (2012: £15.3 million). The advisory fee, payable to 3i plc, is calculated as 1.5% of the Gross Investment Value, which is based on the opening portfolio value and the cost of any new investments made during the year. The advisory fee reduces to 1.25% for any proportion of an asset held for more than five years.

As several of the Company's assets have now been held for more than five years (40% of the portfolio at 31 March 2013), the advisory fee rate chargeable has reduced for those assets. This resulted in a reduction in the advisory fee this year.

The performance fee, calculated as 20% of returns above a performance hurdle of 8% growth in net asset value per annum, totalled £1.4 million (2012: nil). For a more detailed explanation of how fees are calculated, please refer to Note 9.

Operating expenses, comprising Directors' fees, service provider costs and other professional fees, totalled £2.3 million (2012: £2.4 million). The reduction from the prior year relates mainly to costs incurred last year in relation to the conversion of warrants.

Finance costs of £2.9 million (2012: £2.9 million) comprise the arrangement and commitment fees for the Company's £200 million revolving credit facility.

Movements in the fair value of derivatives of £(3.3) million (2012: £5.3 million) represent the fair value movements of the euro hedging programme, and included a £0.6 million

gain on the settlement of derivatives at their maturity.

Balance sheet and cash flows

At 31 March 2013, the Company's net assets totalled £1,103.3 million, or £1,072.3 million after the deduction of the final dividend (2012: £1,040.4 million), comprising the asset portfolio, valued at £918.7 million (2012: £890.8 million), cash and cash equivalents of £179.2 million (2012: £173.4 million), net derivative financial instruments liabilities of £2.5 million (2012: £1.4 million asset) and other current assets of £12.3 million (2012: £4.4 million), primarily relating to accrued income from portfolio investments and prepayments, offset by accrued operating and financing costs of £4.4 million (2012: £3.4 million). A summary balance sheet is included in Table 11.

Cash on deposit was managed actively by the Investment Adviser, and there were regular reviews by the Board of counterparties and their limits. Cash is principally held in AAA rated money market funds, as well as in short-term bank deposits.

There were no external borrowings on a recourse basis to the Company.

Revolving credit facility

At 31 March 2013, the £200 million revolving credit facility held by the Company had not been drawn.

On 2 May 2013, the Company entered into a new, £200 million, three-year facility, on improved terms compared to the previous facility. At the time of reporting, the new facility had not been drawn.

Net asset value per share

The total NAV per share at 31 March 2013 was 125.2p (2012: 121.0p). This reduces to 121.7p (2012: 118.0p) after the payment of the final dividend of 3.52p. There are no dilutive securities in issue following the expiry of the Company's warrants in the previous financial year.

Risk

The Board is ultimately responsible for the risk management of the Company and has a risk management framework (outlined in the table below) which provides a structured and consistent process for identifying, assessing and responding to risks in relation to its strategy and business objectives. Due to the structure of the Company, it is reliant on the risk management framework of the Investment Adviser and other key service providers, as well as on the risk management operations of each portfolio company. The Company manages these risks through updates from the Investment Adviser and other service providers and, where possible, through representation on portfolio companies' boards. The Company also maintains a risk log.

Basis of preparation

Throughout the Investment Adviser's review, the Review of investments and the Financial review sections, the Investment Adviser has presented the Company's net asset value and financial results to show the return on a pro forma investment basis. This information is

in addition to the consolidated financial statements, as required under International Financial Reporting Standards ("IFRS"). The pro forma investment basis presentation provides an alternative representation of the Company's net asset value, shows the Company's cash utilisation for investment and differentiates between non-recourse borrowings held within asset specific acquisition companies and borrowings which may be made at the Company level. The investment basis does not consolidate majority investments and subsidiaries formed specifically for investment purposes in the same way as required under IFRS.

Several adjustments to the consolidated financial statements prepared under IFRS have been made, in order to show returns on an investment basis. The main adjustments are set out below.

3i Infrastructure holds 68.5% of 3i Osprey LP and 87.3% of 3i Networks Finland LP, the vehicles through which it holds its investments in AWG and Elenia respectively. The remaining portions of these entities are held by other third parties. 3i Infrastructure is required under IFRS to consolidate 100% of the results and balance sheet of these limited partnerships into its financial statements on a line-by-line basis. In the investment basis presentation, 3i Infrastructure has recognised only its share of the income and balance sheet of 3i Osprey LP and 3i Networks Finland LP. This adjustment has the effect of eliminating the non-controlling interest entitlement shown in the statement of comprehensive income and the balance sheet prepared on an IFRS basis.

One subsidiary of the Company, 3i Primary Infrastructure 2005-06 LP, which held the investment in Alpha Schools prior to its disposal, has investing partners who are entitled to a 8.75% share of profits, once certain cash hurdle criteria are met. Amounts due to this limited partnership are treated as a non-controlling interest on an IFRS basis but are accrued as an expense in the investment basis.

3i Infrastructure holds two wholly-owned subsidiaries, Oystercatcher Luxco 1 S.à r.l. and Oystercatcher Luxco 2 S.à r.l., ("Oystercatcher Luxco 1" and "Oystercatcher") to fund the minority investment into three subsidiaries of Oiltanking GmbH. External borrowings were obtained by Oystercatcher to partly fund the investments. These borrowings are non-recourse to 3i Infrastructure. Under IFRS, the results and balance sheet of the Oystercatcher Luxco 1 and Oystercatcher subsidiaries are required to be consolidated into 3i Infrastructure's financial statements on a line-by-line basis. In the investment basis presentation Oystercatcher is not consolidated but is accounted for as a portfolio asset held for investment purposes and is held as an investment at fair value accordingly.

Significant accounting policies

3i Infrastructure plc (the "Company") is a company incorporated in Jersey, Channel Islands. The consolidated financial statements for the year to 31 March 2013 comprise the financial statements of the Company and its subsidiaries (together referred to as the "Group"). The Companies (Jersey) Law 1991 does not require the directors of a company to present separate financial statements where consolidated financial statements are presented and therefore the financial results and position of the Company are not presented alongside the consolidated financial statements of the Group.

The financial statements were authorised for issue by the Directors on 9 May 2013.

Statement of compliance

These financial statements have been prepared in accordance with International Financial Reporting Standards, International Accounting Standards and their interpretations as issued by the International Accounting Standards Board.

These financial statements have also been prepared in accordance with and in compliance with the Companies (Jersey) Law 1991.

Basis of preparation

The financial statements of the Group are presented in sterling, the functional currency of the Company and the Group, rounded to the nearest hundred thousand pounds (£0.1 million) except where otherwise indicated.

The preparation of financial statements in conformity with IFRS requires the Board to make judgments, estimates and assumptions that affect the application of policies and reported amounts of assets and liabilities, income and expenses. The estimates and associated assumptions are based on experience and other factors that are believed to be reasonable under the circumstances, the results of which form the basis of determining the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

Key estimates and judgments

The preparation of financial statements in accordance with IFRS requires the Directors to exercise judgment in the process of applying the accounting policies defined below. The following policies are areas where a higher degree of judgment has been applied in the preparation of the financial statements.

(i) Basis of consolidation - The Group holds significant stakes in the majority of its investee companies. The Group must exercise judgment in the level of control of the underlying investee company that is obtained and consider the need to classify certain investee companies as associates, joint ventures or subsidiary undertakings.

(ii) Functional currency - The Group has certain subsidiaries that conduct the majority of their business operations in currencies other than sterling. Judgment has been exercised in determining the appropriate functional currency of these subsidiary undertakings.

The adoption of certain accounting policies by the Group also requires the use of certain critical accounting estimates in determining the information to be disclosed in the financial statements.

Areas where estimates are significant to the consolidated financial statements include:

(i) Valuation of the investment portfolio - The majority of assets in the investment portfolio are valued on a discounted cash flow basis which requires assumptions to be made regarding future cash flows and the discount rate to be applied to these cash flows. Refer to Note 4 for further details of the sensitivity of the carrying value of these investments to the assumptions that have been made.

(ii) Assessment for impairment - The Group must make certain estimates regarding the recoverability of loans and receivables when assessing whether these financial assets meet the criteria for impairment against the current carrying value. Refer to Note 4 for further details of assessments made during the year.

Standards issued but not yet effective

As at 31 March 2013, the following new or amended standards had been issued by the International Accounting Standards Board (IASB).

In 2009, the IASB issued IFRS 9, Financial Instruments - Classification and Measurement, with an expanded and amended version covering additional requirements for financial liabilities issued during 2010. The standard is effective prospectively for accounting periods commencing 1 January 2015 or later and is therefore not applicable for the current accounting period. On adoption, IFRS 9 will require the Group to review the classification of certain financial instruments while allowing the Group to retain the fair value measurement necessary. The Group is in the process of assessing the full impact of these requirements.

During 2011, the IASB issued IFRS 10, Consolidated Financial Statements, IFRS 11, Joint Arrangements, IFRS 12, and Disclosure of Interests in Other Entities, IFRS 13, and Fair Value Measurement. Each of these standards is applicable for periods commencing on or after 1 January 2013.

On adoption, of IFRS 10, IFRS 11 and IFRS 12, the Group will be required to review the entities that it classifies as subsidiaries, joint ventures and associates, and the related disclosures required in respect of each of these types of investments. The Directors of the Company are currently assessing the changes required to the presentation of the Group's financial statements and disclosures.

IFRS 1 (Amendment) Government Loans (effective for accounting periods commencing on or after 1 January 2013).

IFRS 7 (Amendment) - Disclosures - Offsetting Financial Assets and Liabilities (effective for accounting periods commencing on or after 1 January 2013).

IAS 1 (Amendment) Presentation of Items of Other Comprehensive Income (effective for accounting periods commencing on or after 1 July 2012).

IAS 28 (Amendment) Investments in Associates and Joint Ventures (effective for accounting periods commencing on or after 1 July 2014).

IAS 32 (Amendment) Offsetting Financial Assets and Financial Liabilities (effective for accounting periods commencing on or after 1 January 2014).

The following amendments to the standards below are not expected to have a significant impact on the Group once they become effective:

IAS 27, Separate Financial Statements (effective for accounting periods commencing on or after 1 January 2013) and IAS 28, Investments in Associates and Joint Ventures (effective for accounting periods commencing on or after 1 July 2012).

IAS 19 (Amendment) Employee Benefits (effective for accounting periods commencing on or after 1 July 2013).

Interpretations issued but not yet effective

The following new and amended interpretation has been issued by International Financial Reporting Interpretation Committee. The following interpretation is not expected to have a significant impact on the Group.

IFRIC interpretation 20, Stripping Costs in the Production Phase of a Surface Mine, was issued in 2011. It is applicable prospectively for accounting periods commencing 1 January 2013 or later, and is therefore not applicable for the current accounting period.

A Basis of consolidation

(i) Subsidiaries - Subsidiaries are entities controlled by the Group. Control exists when the Company has the power, directly or indirectly, to govern the financial and operating policies of an entity so as to obtain benefit from its activities. The financial results of subsidiaries are included in the consolidated financial statements from the date that control commences until the date that control ceases.

(ii) Associates - Associates are those entities in which the Group has significant influence, but not control, over the financial and operating policies.

Investments that are held as part of the Group's investment portfolio are carried in the balance sheet at fair value even though the Group may have significant influence over those companies. This treatment is permitted by IAS 28, Investment in Associates, which allows investments held by venture capital organisations to be excluded from its scope where those investments are designated, upon initial recognition, as at fair value through profit or loss and accounted for in accordance with IAS 39, with changes in fair value recognised in the statement of comprehensive income in the year.

The Group has no interests in associates outside of the Group's investment portfolio.

(iii) Joint ventures - Interests in joint ventures that are held as part of the Group's investment portfolio are carried in the balance sheet at fair value. This treatment is permitted by IAS 31 Interests in Joint Ventures, which allows interests held by venture capital organisations to be excluded from its scope where those investments are designated, upon initial recognition, as at fair value through profit or loss and accounted for in accordance with IAS 39, with changes in fair value recognised in the statement of comprehensive income in the year.

The Group has no interests in joint ventures outside of the Group's investment portfolio.

(iv) Transactions eliminated on consolidation - Intragroup balances, and any unrealised gains and losses or income and expenses arising from intragroup transactions, are eliminated in preparing the consolidated financial statements.

(v) Non-controlling interests - Non-controlling interests reflect the proportion of the capital of subsidiary undertakings of the Group that is not held by entities within the Group. The proportion of the net assets and profit of the Group that is attributable to non-controlling interests is shown as a separate component within the statement of comprehensive income and the balance sheet. Movements in the net assets attributable to non-controlling interests during the year arising from investment activity, distributions payable to non-controlling interests or movements in the proportion of capital held by non-controlling interests are shown directly in equity through the statement of changes in equity.

B Exchange differences

(i) Foreign currency transactions - Transactions in currencies different from the functional currency of the subsidiary of the Group entering into the transaction are translated at the exchange rate ruling at the date of transaction. Monetary assets and liabilities denominated in currencies different to the functional currency of each Group entity at the financial reporting date are translated to the functional currency at the exchange rate ruling at that date. Foreign exchange differences arising on translation to the functional currency are recognised in the statement of comprehensive income.

Non-monetary assets and liabilities that are measured in terms of historical cost in a foreign currency are translated using the exchange rate at the date of the transactions. Non-monetary assets and liabilities denominated in foreign currencies that are stated at fair value are translated to the functional currency using exchange rates ruling at the date the fair value was determined.

(ii) Financial statements of non-sterling operations - The assets and liabilities of operations whose functional currency is not sterling are translated to sterling at exchange rates ruling at the financial reporting date. The revenues and expenses of these operations are translated to sterling at rates approximating to the exchange rates ruling at the date of the transactions. Exchange differences arising on retranslation are recognised in other comprehensive income and taken to a separate component of equity, the translation reserve, and are released upon disposal of the non-sterling operation.

C Investment portfolio

(i) Recognition and measurement - Investments are recognised and derecognised on a date where the purchase or sale of an investment is under a contract whose terms require the delivery or settlement of the investment. The Group manages its investments with a view to profiting from the receipt of investment income and obtaining capital appreciation from changes in the fair value of equity investments. Therefore, all quoted investments and unquoted equity investments are designated as at fair value through profit or loss upon initial recognition and subsequently carried in the balance sheet at fair value. Loan investments are classified as loans and receivables and subsequently carried in the balance sheet at amortised cost less impairment. All investments are initially recognised at the fair value of the consideration given and held at this value until it is appropriate to measure fair value on a different basis, applying the Group's valuation policy. Acquisition costs are attributed to equity investments and recognised in the statement of comprehensive income.

(ii) Income

(a) Realised gains or losses over value on the disposal of investments is the difference between the fair value of the consideration receivable on disposal less any directly attributable costs, on the sale of equity and the repayment of loans and receivables, and its fair value at the start of the accounting period, converted into sterling using the exchange rates in force at the date of disposal; and are recognised in the statement of comprehensive income.

(b) Unrealised gains or losses on the revaluation of investments is the movement in the fair value of investments between the start and end of the accounting period, or the investment acquisition date and the end of the accounting period, converted into sterling using the exchange rates in force at the end of the period; and are recognised in the statement of comprehensive income.

(c) Portfolio income is that portion of income that is directly related to the return from individual investments. It is recognised to the extent that it is probable that there will be an economic benefit and the income can be reliably measured. The following specific recognition criteria must be met before the income is recognised:

- Dividends from equity investments are recognised in the statement of comprehensive income when the shareholders' rights to receive payment have been established with the exception of dividends paid out of pre-acquisition reserves that are recognised by adjusting the fair value of the equity investment upon acquisition;

- Income from loans and receivables and debt held at fair value through profit or loss is recognised as it accrues by reference to the principal outstanding and the effective interest rate applicable, which is the rate that exactly discounts the estimated future cash flows through the expected life of the financial asset to the asset's carrying value or principal amount;

- Fees receivable represent amounts earned on completion of underlying investment transactions and are recognised on an accruals basis once entitlement to the revenue has been established.

(iii) Impairment of assets held as loans and receivables - All financial assets held as loans and receivables are assessed for impairment on both an individual and a collective basis. The amount of the impairment is measured as the difference between the carrying value of the asset and the net present value of the expected future cash flows expected to arise from each asset, based on the effective interest rate of each asset. The amount of the resultant loss is recognised in the statement of comprehensive income. If the impairment analysis demonstrates that the conditions giving rise to a previously recognised impairment are no longer prevalent, a reversal of the impairment loss is recognised in the statement of comprehensive income.

D Fees

(i) Fees - Fees payable represent fees incurred in the process of acquiring an investment and are measured on the accruals basis.

(ii) Advisory fee - An annual advisory fee is payable to 3i plc based on the Gross Investment Value of the Company. The fee is payable quarterly in advance and is accrued in the period it is incurred. Further explanations are provided in Note 9.

(iii) Performance fee - 3i plc is entitled to a performance fee based on the Adjusted Total Return per ordinary share generated in the period in excess of a performance hurdle. The fee is payable annually in arrears and is accrued in the period it is incurred. Further explanations are provided in Note 9.

(iv) Finance costs - Finance costs associated with loans and borrowings are recognised on an accruals basis using the effective interest method.

E Treasury assets and liabilities

Short-term treasury assets and short- and long-term treasury liabilities are used to manage cash flows and the overall costs of borrowing. Financial assets and liabilities are recognised in the balance sheet when the relevant Group entity becomes a party to the contractual provisions of the instrument.

(i) Cash and cash equivalents - Cash and cash equivalents in the balance sheet comprise cash at bank and in hand and short-term deposits with an original maturity of three months or less. For the purposes of the cash flow statement, cash and cash equivalents comprise cash and short-term deposits as defined above. Interest receivable on cash and cash equivalents is recognised on an accruals basis.

(ii) Bank loans, loan notes and borrowings - Loans and borrowings are initially recognised at the fair value of the consideration received, net of issue costs associated with the borrowings. These issue costs are capitalised and disclosed within Trade and other receivables and amortised over the life of the loan. After initial recognition, loans and borrowings are subsequently measured at amortised cost using the effective interest method, which is the rate that exactly discounts the estimated future cash flows through the expected life of the liabilities. Amortised cost is calculated by taking into account any issue costs and any discount or premium on settlement.

(iii) Derivative financial instruments - Derivative financial instruments are used to manage the risk associated with foreign currency fluctuations of portfolio income, the valuation of the investment portfolio and changes in interest rates on borrowings. This is achieved by the use of forward foreign currency contracts and interest rate swaps. Such instruments are used for the sole purpose of efficient portfolio management. All derivative financial instruments are held at fair value through profit or loss.

Derivative financial instruments are recognised initially at fair value on the contract date and subsequently re-measured to the fair value at each reporting date. All changes in the fair value of derivative financial instruments are taken to the statement of comprehensive income. The maturity profile of derivative contracts is measured relative to the financial contract settlement date of each contract and the derivative contracts are disclosed in the financial statements as either current or non-current accordingly. Realised gains over fair value on the settlement of derivative financial instruments are the difference between the fair value of the consideration receivable on disposal and the fair value at the start of the accounting period, converted into sterling using the exchange rates in force at the date of disposal; and are recognised in the statement of comprehensive income.

F Other assets

Assets, other than those specifically accounted for under a separate policy, are stated at their consideration receivable less impairment losses. The carrying value of such assets or liabilities is considered approximate to their fair value. All assets are reviewed at each balance sheet date to determine whether there is any indication of impairment. If any such indication exists, the asset's recoverable amount is estimated based on expected discounted future cash flows. Any change in levels of impairment is recognised directly in the statement of comprehensive income. An impairment loss is reversed at subsequent financial reporting dates to the extent that the asset's carrying amount does not exceed its carrying value, had no impairment been recognised.

G Other liabilities

Liabilities, other than those specifically accounted for under a separate policy, are stated based on the amounts which are considered to be payable in respect of goods or services received up to the financial reporting date. The carrying value of other liabilities is considered to be approximate to their fair value.

H Equity and reserves

(i) Share capital - Share capital issued by the Company (including the conversion of warrants) is recognised at the fair value of proceeds received and is credited to the stated capital account. Direct issue costs net of tax are deducted from the fair value of the proceeds received.

(ii) Equity and reserves - The stated capital account of the Company represents the cumulative proceeds recognised from share issues or new equity issued on the conversion of warrants made by the Company net of issue costs and reduced by any amount that has been transferred to distributable reserves in previous years. Share capital is treated as an equity instrument, on the basis that no contractual obligation exists for the Company to deliver cash or other financial assets to the holder of the instrument. The retained reserve represents the distributable reserves of the Company. The retained reserve incorporates the cumulative retained profits of the Company (after the payment of dividends) plus any amount that has been transferred from the stated capital account of the Company.

(iii) Dividends payable - Dividends on ordinary shares are recognised as a deduction from retained reserves in the period in which the Company's obligation to make the dividend payment arises.

I Income taxes

Income taxes represent the sum of the tax currently payable, withholding taxes suffered and deferred tax. Tax is charged or credited in the statement of comprehensive income except to the extent that it relates to an amount recognised in the statement of changes in equity when it is recognised directly in this statement.

The tax currently payable is based on the taxable profit for the period. This may differ from the profit included in the consolidated statement of comprehensive income because it excludes items of income or expense that are taxable or deductible in other years and it further excludes items that are never taxable or deductible. The Group's liability for current tax is calculated using tax rates and laws for each relevant tax jurisdiction in which the subsidiaries of the Group operate that have been enacted or substantively enacted by the financial reporting date.

Deferred tax is the tax expected to be payable or recoverable on differences between the carrying amounts of assets and liabilities in the financial statements and the corresponding tax bases used in the computation of taxable profit and is accounted for using the balance sheet liability method.

Statement of Directors' responsibilities

The Directors are responsible for preparing the Annual Report and the financial statements in accordance with applicable law and regulations.

Note to the accounts

1 Segmental analysis

The Directors of the Company review the financial performance of the Group on the "investment basis", as defined in the Returns and risks section. However, the Directors also review information on a regular basis that is analysed by geography and is prepared on a basis that is consistent with the consolidated accounting basis. In accordance with IFRS 8, the segmental information provided below uses this geographic analysis of results as it is the most closely aligned with IFRS reporting requirements. The Group only operates in one service line, being that of an investment holding company. Therefore, no segmental analysis by service line has been produced. The Group is an investment holding company and does not consider itself to have any customers.

The Group received 49% (2012: 70%) of its portfolio income in the year from investments held in the UK and Ireland and 51% (2012: 30%) of portfolio income from investments held in continental Europe. During the year, the Group received income from its investments in Oiltanking of £26.6 million (2012: £29.8 million), Elenia of £23.6 million (2012: nil), AWG of £22.6 million (2012: £29.6 million) and Eversholt of £17.8 million (2012: £33.0 million), which represents 27% (2012: 29%), 24% (2012: nil), 23% (2012: 29%) and 18% (2012: 33%) respectively of the total portfolio income. There was no other income entitlement during the year (or in the comparative year) that represented more than 10% of portfolio income. Given the nature of the Group's operations, the Group is not considered to be exposed to any operational seasonality or cyclicality that would impact the financial results of the Group during the year or the financial position of the Group at 31 March 2013.
