    Chairman's Statement

    PERFORMANCE

    Against a positive backdrop and reduced market volatility, the healthcare
    sector produced a satisfactory return, in line with the wider market over the
    first six months of the Company's financial year. I am pleased to report that
    both the Company's net asset value per share and the share price outperformed
    the Company's Benchmark over the period and that, following last year's strong
    performance, the current financial year has begun on a similarly positive note.

    As can be seen in the chart on the previous page, the Company's net asset value
    total return was +7.4% over the last six months, outperforming the Company's
    Benchmark, the MSCI World Health Care Index measured on a net total return,
    sterling adjusted basis, which returned +2.6%.

    The Company's share price did rather better, with a total return of +10.8%, and
    the Company's share price is now trading consistently at a premium to the
    Company's net asset value per share. The premium of the Company's share price
    to the net asset value per share as at 30 September 2017 was 0.4%.

    I mentioned at the year-end that sterling's decline against other major
    currencies, in particular the U.S. dollar, the currency in which the majority
    of the Company's holdings are denominated, had helped the Company's performance
    in absolute terms. The first six months of the current financial year saw
    something of a recovery in sterling's fortunes, sterling having appreciated
    over 7.0% against the U.S. dollar during the period. This relative dollar
    weakness inevitably detracted from the Company's absolute performance.

    Further information on investment performance and the outlook for the Company
    is given in the Review of Investments.

    CAPITAL

    The Board continues to monitor closely the relationship between the Company's
    share price and the net asset value per share. As referred to above, I am
    pleased to note that due to the Company's strong performance the Company's
    shares have been trading at a small premium to the net asset value per share
    for some months. As a result, and also due to investor demand, a total of
    1,512,500 new shares were issued during the period, at an average premium of
    0.7% to the prevailing cum income net asset value per share, raising £38.4m of
    new funds.

    PERFORMANCE FEE

    I am glad to report that the outperformance generated in this half year has
    resulted in a performance fee becoming payable, in accordance with the
    provisions of the performance fee arrangements, of £2.4 million. This fee was
    shared between the Company's Portfolio Manager, OrbiMed Capital LLC ("OrbiMed")
    and the Alternative Investment Fund Manager, Frostrow Capital LLP ("Frostrow")
    as described in note 3 to the Financial Statements. Shareholders will be aware
    that under new fee arrangements that became effective on 1 April 2017, Frostrow
    no longer receives a performance fee. However, they are entitled to receive any
    performance fee that crystallises during the year ending 31 March 2018 in
    respect of cumulative outperformance attained by 31 March 2017.

    REVENUE AND DIVIDENDS

    The revenue return for the period was £4.2 million, compared to £4.0 million in
    the same period last year; this slight increase comes as a result of a small
    rise in the yield from portfolio investments and despite sterling's
    appreciation against the U.S. dollar in the period. The Board has declared an
    unchanged first interim dividend of 6.5p per share, for the year to 31 March
    2018, which will be payable on 9 January 2018 to shareholders on the register
    of members on 24 November 2017. The associated ex-dividend date is 23 November
    2017. The second interim dividend for the year to 31 March 2018 is expected to
    be announced in June 2018.

    I remind shareholders that it remains the Company's policy to pay out dividends
    to shareholders in the quantum necessary to maintain investment trust status
    for each financial year. These dividend payments are paid out of the Company's
    net revenue for the year and, in accordance with investment trust rules, only a
    maximum of 15% of income arising from the shares and securities making up the
    investment portfolio can be retained by the Company in any financial year.

    It is the Board's continuing belief that the Company's capital should be fully
    deployed rather than paid out as dividends to achieve a particular target
    yield.

    HALF YEAR REPORT & ACCOUNTS

    As I mentioned last year, in order to keep costs to a minimum we will not be
    providing a hard copy of this year's Half Year Report & Accounts. This document
    is, and will continue to be available on the Company's website at 
    www.worldwidewh.com. The Company's Annual Report & Accounts will continue to be
    available in hard copy, and also on the Company's website.

    OUTLOOK

    Our Portfolio Manager believes that investors are now focusing more on the
    sector's strong fundamentals rather than political uncertainty, with factors
    such as strong revenue generation, continued high levels of innovation, a more
    benign approval environment at the FDA and expected increased merger and
    acquisition activity expected to be key drivers. In addition, anticipated U.S.
    tax reforms and cash repatriation are also expected to be positive for the
    sector. However, on a cautionary note, volatility remains an issue as evidenced
    by the recent correction in the biotechnology sector.

    Our Portfolio Manager's focus remains on the selection of stocks with strong
    prospects and we reiterate our belief that the long-term investor in the
    healthcare sector will be well rewarded.

    Review of Investments

    MARKETS

    Global equity markets for the six-month period from 1 April to 30 September
    2017 advanced with admirable aplomb, reaching multiple new all-time highs
    throughout the period. Despite some spikes, volatility also remained relatively
    low. Overall, strong corporate earnings and positive economic trends supported
    the move higher, with little offsets as political risk in Europe eased and
    despite tensions between North Korea and the United States. Emerging markets
    also benefitted from a supportive global backdrop.

    Perhaps the only sources of volatility during the period were various key
    global currencies, notably the euro and to a lesser extent, sterling, which
    blunted some of the index returns, compared to a U.S. dollar perspective.

    Healthcare stocks followed a similar trend as the broader market, with solid
    and mostly consistent advances and the achievement of all-time highs in the
    six-month period. Again, solid fundamentals coupled with reduced macro concerns
    fueled the move higher, partially diminished by currency moves.

    PERFORMANCE

    We are pleased to report that the Company outperformed both the broader market
    and the Benchmark, with a share price total return of +10.8% and a net asset
    value total return of +7.4% in the six-month period. Performance of the
    Benchmark for the six-month period ended 30 September 2017 was +2.6%. This
    compares to the MSCI World Index return of +2.4% (measured in sterling terms).

    Over a 12-month period, the Company has significantly outperformed its
    Benchmark, with a share price total return of +20.7% and a net asset value
    total return of +14.5% compared to the Benchmark return of +8.8%.

    Sources of absolute and relative contribution were both diverse and numerous.
    All sub-sectors contributed to positive returns, with only one exception,
    generic pharmaceuticals, primarily due to the degradation of fundamentals in
    that sector. Otherwise the strong performance recorded for the interim period
    was mostly driven by allocation and stock picking in biotechnology and medical
    technology & device stocks. The former was driven by a large rebound in share
    prices after the dramatic drawdown observed in 2016 and the latter fueled by an
    innovation and growth cycle that had not been seen in years. Otherwise, stock
    returns in large capitalisation pharmaceuticals, specialty pharmaceuticals,
    life science & services, and managed care/services were all positive.

    MAJOR CONTRIBUTORS TO PERFORMANCE

    The top individual stock contributors to performance come from a variety of
    sub-sectors and geographies, from biotechnology, to pharmaceuticals, and
    medical devices, from the United States, to Denmark, and Japan.

    Oncology continues to be the hottest therapeutic category for healthcare
    investors in 2017. Puma Biotechnology, is an emerging biotechnology company
    whose lead asset is an oral once-daily tyrosine kinase inhibitor called Nerlynx
    (neratinib), designed to treat a specific form of early stage breast cancer.
    The stock rose substantially during the period due to a favourable U.S. Food
    and Drug Administration ("FDA") Advisory Committee vote in May 2017, that
    recommended approval of Nerlynx. Subsequently, the drug was approved in July
    2017 and launched shortly thereafter. Prior to these events, there had been
    significant investor scepticism about the asset's approvability due to its
    perceived modest survival benefit and significant tolerability issues. As a
    result, the successful commercialisation of Nerlynx by Puma has fueled merger
    and acquisition ("M&A") speculation, and the share price has more than doubled
    during the period.

    BeiGene, is a China-based biotechnology company focused on the development of
    oncology drugs that serve both local and global markets. The company has
    parlayed its expertise in cell biology and chemistry into a pipeline of four
    clinical-stage oncology candidates. BeiGene's lead candidate, BGB-3111 which
    targets "BTK" (Bruton's tyrosine kinase), was designed to have specificity and
    potency advantages over established BTK inhibitors in the treatment of various
    blood cancers. The company has commenced late stage clinical development to
    demonstrate its superiority, increasing investor enthusiasm about its
    blockbuster potential and buoying the share price. BeiGene's other oncology
    candidates in earlier phases of development are also directed at validated
    oncology targets (such as "PD-1", "PARP", or "BRAF") and also may have
    best-in-class properties. As such, the share price also moved higher in the
    period after the company announced a strategic collaboration with Celgene for
    BeiGene's PD-1 inhibitor, representing BeiGene's entry into the "hot" space of
    immuno-oncology.

    A true leader in medical device innovation, Intuitive Surgical, develops
    robotic systems and associated instrument sets for use in a broad array of
    surgical procedures. Shares in the company consistently outperformed during the
    six-month period for a number of reasons. Robotic procedure volumes and new
    system placements, both leading indicators of sales performance, strongly
    outperformed analyst expectations in the period. Additionally, the company
    announced and launched a new robotic system, da Vinci X, which is designed to
    be more affordable and is positioned favourably against upcoming competitive
    robotic systems. Lastly, the company was at the early stages of a new robotic
    launch in China for a lung biopsy product which represents a significant market
    opportunity and has driven longer-term consensus estimates and valuations
    higher for the stock.

    Japan, historically, has often been a hidden gem for innovation, and Nippon
    Shinyaku is a perfect example. The company developed a best-in-class treatment
    for a deadly lung disease known as pulmonary arterial hypertension or PAH.
    Uptravi (selexipag) was discovered by Shinyaku and licensed to Swiss-based
    leaders in PAH, Actelion, nearly 10 years ago. The drug was successfully
    launched by Actelion in 2016, drawing the attention of global drug giant,
    Johnson and Johnson, who subsequently acquired Actelion early in 2017. As a
    result, Shinyaku began to receive greater recognition by investors for this
    potential blockbuster product. Subsequently, Nippon Shinyaku has been one of
    the best performing Japanese pharma stocks in 2017.

    The worldwide leaders in the treatment of diabetes, Novo Nordisk, came under
    pressure in 2016 as pricing, in particular insulin pricing, was squeezed by
    payers and competition alike. However, 2017 bore witness to greater pricing
    stability and more clarity on the next wave of innovation for the treatment of
    one of the most common diseases in the world. While not completely de-risked,
    Novo's next generation offering, "semaglutide" is poised to be the most
    efficacious treatment ever developed for the treatment of Type II diabetes.
    Moreover, the company is developing the compound in both injectable and oral
    formulations. If the latter can successfully pass through clinical trials, it
    can surely be a mega-blockbuster product. These developments pushed Novo's
    stock price higher during the six-month period.

    MAJOR DETRACTORS FROM PERFORMANCE

    The largest detractors from performance, similar to the top contributors, were
    very diverse in nature. Detractors came from many subsectors, including medical
    devices, generics, biosimilars, biotechnology, and hospitals. In each case,
    however, an unexpected negative catalyst caused the share price decline.

    The medical device maker, Wright Medical, one of our major holdings,
    manufactures state-of-the-art joint replacements, primarily for shoulder, foot
    and ankle, trauma and sports medicine procedures, as well as orthobiologic
    products. Earlier this year, the company materially accelerated its plans to
    expand its sales force, leading to a brief disruption in the first quarter and
    subsequently a shortfall in sales relative to consensus expectations. While the
    second quarter showed a reacceleration in sales trends, the positive impact on
    the stock was overshadowed by two hurricanes that struck the high-volume
    regions of Florida and Texas in September, delaying procedures and leading
    investors to question whether management will be able to hit the guidance range
    for the full year. The share price fell sharply in the last month of the period
    as a result.

    Shares of Mylan, a global generic drug manufacturer, plummeted in August in
    response to a second-quarter earnings miss and downwardly-revised full-year
    financial guidance. Similar to other companies with significant exposure to the
    U.S. generic drug market, Mylan's operating performance has been stifled by a
    combination of increased competitive pressures on its legacy generic drug
    portfolio and delayed U.S. FDA approvals/launches of generics for significant
    branded products.

    Another hot topic in healthcare investing has been biosimilars: generic
    versions of complex, biologic drugs. However, monetising this global
    opportunity has proven more difficult. Coherus Biosciences, is developing
    biosimilar versions of a number of branded biotechnology drugs, including the
    white blood cell stimulator Neulasta (pegfilgrastim) and the rheumatoid
    arthritis drugs Humira (adalimumab) and Enbrel (etanercept). The company had
    filed an application for their lead asset, a biosimilar version of Neulasta, in
    August 2016. However, in June 2017, the stock dropped significantly when the
    U.S. FDA rejected the drug, stating that the company needed to re-analyse
    certain patient samples with a revised immunogenicity assay. Due to the
    setback, the company was forced to reduce its workforce by 30%. The company
    also suffered a legal setback, and another share price decline, when its
    attempt to invalidate a patent protecting Humira was rejected by the U.S.
    Patent & Trademark Office in September of 2017.

    Incyte is a Delaware-based biotechnology company. The company markets Jakafi
    (ruxolitinib) for myeloproliferative disorders (abnormal growth of blood cells)
    and is developing a portfolio of therapeutics for the treatment of cancers.
    Baricitinib, a next generation JAK inhibitor for rheumatology, was unexpectedly
    rejected for approval by the U.S. FDA due to rare safety concerns, despite
    earlier European approval, causing the stock to fall. While the stock partially
    recovered, investor angst rose in relation to Incyte's first-in-class IDO
    inhibitorm epacadostat, a novel cancer treatment in late stage clinical
    development. Despite early positive data that suggested epacadostat has the
    potential to be a major player in cancer immunotherapy, the stock again
    sold-off after many investors decided to de-risk by selling the stock ahead of
    the next looming data update for the molecule.

    HCA Healthcare, is the largest public hospital provider in the U.S. The past 12
    months have proven turbulent for the company's business and share price,
    starting with the lead into the U.S. Presidential election in November 2016.
    For the six-month period reported here, the company reported weak earnings and
    reduced full year 2017 guidance due to decelerating utilisation trends. In
    addition, the stock underperformed due to concerns that Republicans would
    successfully repeal President Obama's Affordable Care Act (or "Obamacare"),
    which would reduce the number of American citizens with health insurance.

    SECTOR DEVELOPMENTS

    Whilst 2016 was marked primarily by landmark political events such as the
    prospective withdrawal of the United Kingdom from the European Union (commonly
    known as Brexit) and the unexpected election of Donald Trump as the 45th
    President of the United States, 2017 can thus far be characterised as a return
    to fundamentals for global healthcare equites; and the fundamentals are good.

    Politics are never completely obviated, however, and the current situation has
    been quite favourable for therapeutic stocks in the six-month period,
    especially in the largest drug market in the world, the United States.

    First, with Republicans in power, the concern over a dramatic overhaul to drug
    pricing rules in the U.S. has dropped considerably (despite the odd Tweet to
    the contrary from constantly combative President Trump). Second, President
    Trump has proposed his plans for significant tax reform in the U.S. Of import
    to the healthcare industry are twofold: (1) the substantial lowering of the
    U.S. corporate tax rate and (2) a "tax holiday" for the repatriation of
    overseas cash. If adopted, in whole or in part, it would be a windfall of
    earnings and cash flows for all large, U.S. domiciled healthcare companies. In
    particular, large capitalisation pharmaceutical and biotechnology companies,
    such as Pfizer or Amgen would reap significant rewards given they possess -
    cumulatively - hundreds of billions of U.S. dollars of cash overseas. It would
    be a boon to the industry and almost assuredly stimulate a M&A frenzy.

    Further, whilst the new Commissioner of the U.S. FDA, Scott Gottlieb, has
    introduced some new plans to increase competition (with the hope to affect drug
    prices) in the U.S. drug market, overall, he is viewed as very aligned with the
    drug industry's best interests. Dr. Gottlieb's "Drug Competition Action Plan"
    will accelerate generic drug approvals (he inherited an FDA backlog of over
    2,600 generic drugs seeking approval), ease generic versions of complex and
    biologic drugs onto the market, and seek to reduce the number of older
    medicines that lack generic competition by regularly highlighting the nearly
    200 off-patent drugs with no generic alternatives available. This approach is
    appealing, utilising a market-based, lower regulation approach favoured by
    conservatives to deliver the drug price cost containment desired by
    progressives. Generic drug competition is an effective and under-appreciated
    tool for lowering drug prices over time that, importantly, does not stifle
    innovation.

    Moreover, what is the FDA's scorecard? It is not a perfect measure, but we note
    that as of 30 September 2017, the FDA had approved 34 novel drugs for the U.S.,
    already eclipsing the total for all of last year and a 100% increase
    year-over-year. This total does not include another 12 new cancer indications
    granted to already approved "immuno-oncology" drugs, one of the most innovative
    advances in the treatment of cancer over the past three decades.

    Finally, a comment on M&A, a secular theme for us and most healthcare
    investors, but the modest pace and subdued level of M&A activity seen in 2017
    has been a source of frustration. However, we do note the August 2017
    blockbuster transaction with Gilead's U.S.$11 billion acquisition of Kite
    Pharmaceuticals. Kite is one of the pioneers of CAR-T immunotherapy a next
    generation variation of gene therapy that reprograms a patient's own T-cells to
    attack malignancies. The large valuation is a compelling validation of
    biotechnology innovation considering Kite is still a pre-revenue company with
    no approved products. We believe more such transactions will occur, with a
    potential feeding frenzy of activity possible if a U.S. tax reform package is
    enacted with a repatriation provision for offshore cash balances held by U.S.
    companies, as discussed above.

    STRATEGY REVIEW

    The Company's mandate remains unchanged: to seek innovation and growth in the
    healthcare industry on a global level by investing in healthcare companies that
    offer the greatest return potential, being mindful of risk. As productivity and
    innovation rise, the number of investable ideas also rises, but the scrutiny
    and diligence required to isolate them becomes more complex.

    Biotechnology

    The major biotechnology sub-sector continued its recovery during the six-month
    period as macro concerns about the biotechnology sector continued to abate.
    Heading into 2017, investors were principally concerned about two issues
    overhanging the biotechnology sector: 1) any policy announcement by President
    Trump about his plan to lower drug prices, and 2) the potential repeal of
    "Obamacare", President Obama's signature healthcare reform bill.

    However, despite making public comments about high drug prices on numerous
    occasions since the election, President Trump has yet to announce any official
    plan to reduce drug prices. Moreover, investors now believe he will no longer
    do so and has moved on to other policy priorities.

    In addition, despite controlling both the Presidency and Congress, the
    Republicans have failed to repeal Obamacare despite multiple attempts. The
    biotechnology industry is less sensitive to the fate of Obamacare, but
    uncertainty around the future of the healthcare system in the United States hadcaused many investors to avoid the healthcare sector altogether. As the
    prospects for a near-term repeal of Obamacare have dimmed, the cloud of
    uncertainty surrounding healthcare has lifted somewhat. With these macro
    overhangs dissipating, sentiment on the biotechnology sector has improved and
    investors have begun to realise the attractive valuation of major biotechnology
    relative to other sectors.

    Meanwhile, the regulatory environment for the biotechnology and pharmaceutical
    sectors has remained extremely favourable, with drug approvals occurring in a
    timely manner despite less-than-perfect data sets. Initial product launches
    from select large capitisation biotechnology companies have exceeded
    expectations, including Biogen's launch of Spinraza (nusinersen), a novel
    treatment for spinal muscular atrophy, and Regeneron Pharmaceutical's launch of
    Dupixent (dupilumab), a novel antibody for atopic dermatitis. Moreover, these
    drugs have launched with significant price tags, costing hundreds of thousands
    of dollars and tens of thousands of dollars, respectively.

    We would also highlight that this year has been important for the development
    of new treatment modalities from small capitalisation biotechnology stocks. 
    Spark Therapeutics' voretigene neparvovec is poised to be the first gene
    therapy approved by the FDA. Alnylam Pharmaceuticals recently reported positive
    phase III data for patisiran for hereditary ATTR amyloidosis. This is the first
    successful pivotal trial of an RNA-interference based therapy, which is a novel
    class of drugs to downregulate expression of genes. Advances with new
    therapeutic platforms such as gene therapy, RNA-interference, and CAR-T will
    expand the capabilities of the industry to target diseases that were previously
    not addressable by conventional drug therapies.

    Whilst M&A activity has been relatively quiet, this is likely due to
    uncertainty about the specifics of President Trump's corporate tax reform plan.
    We would expect activity to reaccelerate once there is more clarity on tax
    reform, which is expected at the end of 2017 or perhaps early in 2018. Even so,
    M&A activity has not been completely absent given the "innovation engine" of
    emerging biotechnology stocks discussed above,

    Pharmaceuticals

    Pharmaceutical stocks, like their biotechnology brethren, have enjoyed a
    renaissance in 2017 as the political overhang has vastly diminished, allowing
    investors to look past the rhetoric and focus on fundamentals; in the case of
    large capitalisation pharmaceutical stocks, those fundamentals are arguably
    mixed.

    Perhaps most important is that innovation in drug discovery and development
    appears to be at or near all-time highs, and nothing drives value and accretion
    like new product flow. However, we do note the inherent heterogeneity within
    the companies who comprise this universe. In other words, innovation is not
    spread equally across them all, and thus we believe stock selection is key.

    Whilst "patent cliffs" are currently at a low level, looming losses of
    exclusivity across this sector are not de minimis. Once again, patent
    expirations are not spread equally across the group, hence the growth outlook
    can be quite variable amongst these peers. In addition, a new "cliff" is on the
    horizon with respect to biosimilars. A host of blockbuster antibody drugs are
    poised to lose patent protection over the next three to five years. However,
    the approval, uptake, utilisation, and interchangeability of the biosimilar
    product to replace the incumbent brand remains a source of investor debate and
    thus a source of market uncertainty.

    In the U.S., whilst angst over drug pricing from a political perspective has
    subsided, payers and managed care players have become much more savvy with
    trading patient access for increased rebates and this has become a hot button
    topic for drug companies and investors alike. While generic drug prices
    continue to decline, branded drug prices continue to rise, and are even
    accelerating given the increased approval rate of higher priced "specialty"
    drugs (such as biologics across many therapeutic areas including oncology,
    rheumatology, immunology, dermatology, etc.). The payer's response to this is
    to manage patient access to new drugs with tight controls such as step therapy,
    prior authorisation, restricted drug lists, high deductibles, and increased
    co-pays. The result can dramatically impact the uptake of a new drug launch. Of
    course, truly innovative new drugs with real value propositions - such as an
    increase in patient survival - can overcome such hurdles.

    For small capitalisation pharmaceutical stocks, the performance of U.S.-focused
    specialty and generic pharmaceutical companies has disappointed, as companies
    continued to struggle with the multiple challenges facing the sector,
    including: reduced pricing power, heavy debt burdens, heightened competitive
    pressures, underperforming assets, increasingly restrictive third-party payer
    formularies - including reduced coverage of new product introductions - and,
    unsurprisingly, senior management changes.

    Although valuations remain depressed for many companies in the specialty and
    generic pharmaceutical sector, we see opportunities in a handful of
    reasonably-leveraged companies with important upcoming clinical and regulatory
    events and differentiated new product introductions benefitting from a lesser
    degree of third-party payer management. We anticipate that increased M&A
    activity, including greater participation from private investors, could improve
    sentiment for this group of beleaguered stocks and drive valuation recoveries
    over the next 12 months.

    Medical Technology and Devices

    A number of factors for the medical technology and devices spaces remain
    favourable and thus we have a positive view on a forward-looking basis. First,
    organic growth rates are tracking at healthy levels whilst reported growth
    rates are benefitting from small and mid-size acquisitions. Undeniably,
    absolute valuations remain high, but relative valuations against the S&P 500
    Index are now roughly in line with historical averages despite relatively
    superior earnings per share growth in the "MedTech" sector.

    Importantly, we view current earnings growth rates as sustainable through the
    end of the decade, at least. Though there has been some investor consternation
    surrounding U.S. hurricane-related adverse impacts to sector volumes for the
    third quarter earnings period, we believe that these are one-time events. In
    our view, procedures are more likely to be delayed into the fourth quarter than
    cancelled outright and underlying procurement volume trends remain strong.

    Lastly, U.S. tax reform remains a key catalyst for almost all MedTech
    companies, as does the potential delay or repeal of the medical device excise
    tax. Turning to stock selection, we continue to prefer (1) cardiology - where
    innovation remains industry leading, (2) surgical robotics - where technology
    advances have been and will continue to be disruptive to historical surgical
    paradigms, and (3) extremities implants/biologics - which remain at the very
    early stages of the adoption curve.

    Life Sciences Tools and Services

    We remain somewhat guarded for the prospects of the life science tools space.
    Certainly valuation continues to be demanding in both relative and absolute
    sense. Nevertheless, outperformance in the past six months was driven by a
    perceived political and regulatory shield from an unpredictable administration
    and healthy end markets.

    Federal funding environments in bio-pharma and academic research institutions
    remains buoyant driven by excitement around developments in oncology. Despite
    healthy end markets, valuation and sub-sector rotation dynamics will play even
    more of a critical role in positioning as we look ahead into 2018. Major U.S.
    corporate tax reform and subsequent repatriation of overseas cash could
    catalyse material M&A, especially in bio-pharma. However, the consolidation of
    bio-pharma could pressure the life sciences tools sector as pharmaceutical
    companies rationalise their research and development ("R&D") programmes.
    Coupled with this potential headwind and aforementioned valuation, we remain
    selective in life sciences tools.

    The diagnostics industry, as has been the case for the last several years,
    remains an industry beholden to reimbursement policies set by both private
    payers and U.S. Medicare. Utilisation has seen both ups and downs during this
    period with "Obamacare" backed tailwinds offset by severe weather-related
    headwinds.

    More importantly, the industry hit a major fundamental set back this year when
    the Protecting Access to Medicare Act enacted legislative reimbursement cuts
    for Medicare lab fee services that were more draconian than expected. Set to
    take effect from January 2018, if finalised, Medicare reimbursement for high
    volume lab tests could be reduced by up to 10%.

    The remainder of 2017 could be quite volatile as the lab industry awaits the
    final ruling after a contentious public hearing period. Given the expected
    reimbursement cuts and potential reduction in insured lives under the new
    administration's political efforts, we remain cautious on the sector until
    further clarity can be observed.

    Healthcare Services

    In healthcare services, payers have outperformed providers due to weaker than
    expected utilisation of healthcare. Specifically, payers such as health
    maintenance organisations (also known as HMOs, a type of health insurance plan
    that usually limits coverage to care from doctors who work for or contract with
    that HMO), reported strong earnings upside and raised full year 2017 guidance.
    In contrast, providers such as hospitals experienced decelerating volumes and
    reduced their financial outlooks for the year. (Severe hurricanes that plagued
    the southern United States in September 2017 were also disruptive, although
    generally viewed as one-time non-recurring impacts.)

    Macroeconomic trends have also favoured payers over providers. For example,
    payers stand to benefit most from corporate tax reform because all of their
    business is conducted in the U.S. and from rising interest rates because they
    would generate higher income on investment portfolios. Rising interest rates is
    bad for levered hospitals.

    Going forward we remain bullish on HMOs with a view that utilisation will
    remain modest, the macroeconomic environment benign, and the regulatory
    environment under the Trump administration favouring the private sector over
    Obamacare. We remain bearish on provider stocks including hospitals because
    they are negatively impacted by these conditions. Separately, we are bearish on
    Pharmacy Benefit Managers ("PBM"s) (who serve as the middlemen between
    insurance companies, pharmacies and manufacturers to secure lower drug costs
    for insurers and insurance companies) as this industry transitions from a
    disciplined duopoly to an increasingly competitive and more transparent market
    due to new entrants.

    Emerging Markets

    Throughout 2017, the Chinese government has continued to enact reforms to raise
    drug quality, improve regulatory speed and efficiency, and promote innovation.
    To improve overall drug quality in China, the government has been enforcing
    bioequivalence standards for generic drugs, forcing companies to certify the
    quality of their clinical trial data, and allowing more foreign high-quality
    drugs into the Chinese market. These reforms have led to a dramatic drop in the
    backlog of drugs pending review at the China Food and Drug Administration
    ("CFDA"), as lower-quality pharmaceutical companies with deficient data
    packages have pulled their applications.

    To improve regulatory speed and efficiency, the CFDA has been approving
    clinical trial initiations more quickly, adding more drug reviewers, and
    improving the frequency and quality of communication between the sponsor and
    the agency. To promote innovation, the Chinese government has been accelerating
    the regulatory review of innovative drugs, increasing reimbursement of
    innovative drugs, and decreasing reimbursement of drugs with questionable
    clinical data. These reforms have occurred while implementing regulations to
    discourage over-prescribing of drugs and enacting rules to simplify the drug
    distribution chain to remove cost.

    In the short-term, all of these policies have led to a fall in prescription
    drug sales. Over the long-term, we believe these policies are positive for the
    innovative drug industry and will remove many of the low-quality companies that
    have historically pressured prices. Indeed, the regular drug price cuts that
    have characterised the industry have been more moderate recently than in the
    past. We continue to favour Chinese players with innovative pipelines in light
    of these policies.

    The Indian pharmaceutical industry has recently experienced several regulatory
    headwinds and policy changes, but despite these challenges the underlying
    demand in the sector remains robust. The industry's growth rate has declined to
    c.3.0% during the reported period, down from c.10.0% the previous year. The
    reasons behind this slowdown are multifactorial, including the introduction of
    the Goods and Services Tax (GST) that triggered trade inventory corrections,
    and the impact of the new draft pharmaceutical policy aimed at controlling
    costs and stoking competition. We anticipate continued volume growth for the
    industry due to strong underlying demand owing to rising disposable income,
    increasing insurance penetration, improving medical infrastructure, and
    increasing incidence of chronic diseases. That said, we are closely monitoring
    industry pricing dynamics, with a keen eye on the potential negative impact of
    additional government cost control initiatives. This could emerge as an
    important near-to-intermediate-term risk.

    Indian companies with significant exposure to the U.S. generic drug market have
    also faced additional challenges, similar to their U.S.-based competitors.
    These challenges include: (1) increasing regulatory scrutiny on both
    manufacturing and marketing operations, (2) customer consolidation, and (3)
    higher than expected base business price erosion. Despite these challenges, the
    U.S. market remains an important contributor of revenues and profits to most
    Indian pharmaceutical companies. Such challenges should help well-run Indian
    companies become more compliant and cost efficient, allowing management to
    strengthen and re-focus product pipelines toward differentiated generics.

    Additionally, Indian pharmaceutical companies have benefited from the high
    double-digit growth rates witnessed in emerging markets such as South East
    Asia, Middle East, Africa, and Eastern Europe. Currency dynamics in some of
    these geographies have become more favourable allowing Indian companies to reap
    the benefits of widely diversified product baskets via leverage of supply
    agreements and acquisitions reached in quarters past.

    Our strategy in India is multifold. We strive to invest in (1) high quality
    companies with a focus on high growth chronic segments in the domestic market,
    (2) companies that prioritise compliant manufacturing and have a significant
    and growing U.S. exposure with a focus on a differentiated generics pipeline,
    and (3) companies with high growth and profitable emerging market exposure.

    OUTLOOK FOR 2018

    Despite recent volatility in the biotechnology sector our collective optimism
    is high for 2018. Global healthcare stocks are clearly now trading on
    fundamentals again rather than retreating on political rhetoric. Importantly,
    our view on the fundamentals of healthcare is decidedly positive, and we expect
    continued moves higher as secular demand and consumption of healthcare goods
    and services should continue unabated.

    Therapeutic stocks, pharmaceuticals and biotechnology, will continue to prosper
    during this golden era of innovation. While the fruits of genomics were not
    ripe enough to pick at the turn of the century, today's discoveries are turning
    into real drugs with real benefits to patients and the entirety of the
    healthcare system. Political risk for the sector is perhaps at an all-time
    modern low. In fact in the U.S., politics may turn into a tailwind in 2018 if
    tax reform can be enacted, creating even more cash flow into a system which
    notably benefits from such circumstances.

    Overall, with technical and macro pressures fading, company-specific events
    that are central to our investment process should return to prominence, with
    clinical, regulatory and M&A catalysts driving individual stock price
    performance.

    Interim Management Report

    PRINCIPAL RISKS AND UNCERTAINTIES

    The principal risks and uncertainties associated with the Company are set out
    on pages 22 to 24 of the Annual Report & Accounts for the year ended 31 March
    2017, which is published on the Company's website. Such risks and uncertainties
    are as applicable for the remaining six months of the Company's financial year
    as they have been for the period under review. The risks can be summarised
    under the following headings: Investment (including leverage risks);
    Operational (including financial, corporate governance, accounting, legal,
    cyber security and regulatory risks); and, Strategic (including shareholder
    relations and share price performance).

    The Board acknowledges the continued uncertainty surrounding the UK's decision
    to leave the EU. However, the Board does not consider that this decision has
    significantly altered the risk profile of the Company as the vast majority of
    the Company's investments are based outside the EU.

    RELATED PARTY TRANSACTIONS

    During the first six months of the current financial year no material
    transactions with related parties have taken place which have affected the
    financial position or the performance of the Company during the period.

    GOING CONCERN

    The Directors believe, having considered the Company's investment objectives,
    risk management policies, capital management policies and procedures, nature of
    the portfolio and expenditure projections, that the Company has adequate
    resources, an appropriate financial structure and suitable management
    arrangements in place to continue in operational existence for the foreseeable
    future and, more specifically, that there are no material uncertainties
    relating to the Company that would prevent its ability to continue in such
    operational existence for at least twelve months from the date of the approval
    of this half yearly financial report. For these reasons, they consider there is
    reasonable evidence to continue to adopt the going concern basis in preparing
    the accounts.

    DIRECTORS' RESPONSIBILITIES

    The Board of Directors confirms that, to the best of its knowledge:

    (i)      the condensed set of financial statements contained within the Half
    Year Report and Accounts has been prepared in accordance with the Financial
    Reporting Standard 104 (Interim Financial Reporting); and

    (ii)     the interim management report includes a fair review of the
    information required by 4.2.7R and 4.2.8R of the UK Listing Authority
    Disclosure Guidance and Transparency Rules.

    In order to provide these confirmations, and in preparing these financial
    statements, the Directors are required to:

    -       select suitable accounting policies and then apply them consistently;

    -       make judgments and accounting estimates that are reasonable and
    prudent;

    -       state whether applicable UK Accounting Standards have been followed,
    subject to any material departures disclosed and explained in the financial
    statements; and

    -       prepare the financial statements on the going concern basis unless it
    is inappropriate to presume that the Company will continue in business;

    and the Directors confirm that they have done so.

    The Half Year Report has not been reviewed or audited by the Company's auditor.

    The "Total" column of this statement is the Income Statement of the Company.
    The "Revenue" and "Capital" columns are supplementary to this and are prepared
    under guidance published by the Association of Investment Companies. All
    revenue and capital items in the above statement derive from continuing
    operations and the net return/(loss) after taxation is attributable to the
    owners of the Company.

    The Company has no recognised gains and losses other than those shown above and
    therefore no separate statement of Total Comprehensive Income has been
    presented.

    Notes to the Financial Statements

    1. ACCOUNTING POLICIES

    The condensed Financial Statements for the six months to 30 September 2017
    comprise the statements set out on the previous pages with the related notes
    below. They have been prepared in accordance with FRS 104 'Interim Financial
    Reporting', the AIC's Statement of Recommended Practice issued in November 2014
    ('New SORP') and using the same accounting policies as set out in the Company's
    Annual Report and Financial Statements at 31 March 2017.

    Going concern

    After making enquiries, and having reviewed the Investments, Statement of
    Financial Position and projected income and expenditure for the next 12 months,
    the Directors have a reasonable expectation that the Company has adequate
    resources to continue in operation for the foreseeable future. The Directors
    have therefore adopted the going concern basis in preparing these condensed
    financial statements.

    Fair value

    Under FRS 102 and FRS 104 investments have been classified using the following
    fair value hierarchy:

    Level 1 - Quoted market prices in active markets

    Level 2 - Prices of a recent transaction for identical instruments

    Level 3 - Valuation techniques that use:

    (i)      observable market data; or

    (ii)     non-observable data

    OrbiMed and £222,000 was payable to Frostrow, and a provision of £10,331,000
    (31 March 2017: £3,387,000). This provision, relating to outperformance
    generated at 30 September 2017, will only become payable at future performance
    fee calculation dates in the event that the current outperformance is
    maintained. The maximum amount that could become payable by 30 September 2018,
    in the event that outperformance is maintained is £10,331,000.

    With effect from 1 April 2017 the AIFM fee was amended to 0.30% of the market
    capitalisation up to £150 million, 0.20% in excess of £150 million and up to £
    500 million, 0.15% in excess of £500 million and up to £1 billion, 0.125% in
    excess of £1 billion to £1.5 billion, and over £1.5 billion 0.075%, plus a
    fixed amount equal to £57,500 per annum. The Portfolio Management fee remained
    unchanged at 0.65% per annum of the Company's NAV.

    The performance fee provision is calculated quarterly by comparing the
    cumulative performance of the Company's NAV with the cumulative performance of
    the Benchmark since the launch of the Company in 1995. For performance fees
    payable to 31 March 2018 relating to outperformance attained by 31 March 2017,
    the performance fee is 16.5% of any outperformance over the Benchmark, with
    OrbiMed receiving 15% and Frostrow receiving 1.5%. For outperformance generated
    from 1 April 2017 the performance fee is 15% of any outperformance over the
    Benchmark payable to OrbiMed.

    Glossary

    Alternative Investment Fund Managers Directive (AIFMD)

    Agreed by the European Parliament and the Council of the European Union and
    transported into UK legislation, the AIFMD classifies certain investment
    vehicles, including investment companies, as Alternative Investment Funds
    (AIFs) and requires them to appoint an Alternative Investment Fund Manager
    (AIFM) and depositary to manage and oversee the operations of the investment
    vehicle. The Board of the Company retains responsibility for strategy,
    operations and compliance and the Directors retain a fiduciary duty to
    shareholders.

    Benchmark

    The performance of the Company is measured against the MSCI World Health Care
    Index on a net total return, sterling adjusted basis. Prior to 1 October 2010
    performance was measured against the Datastream World Pharmaceutical &
    Biotechnology Index (total return, sterling adjusted).

    Discount or Premium

    A description of the difference between the share price and the net asset value
    per share. The size of the discount or premium is calculated by subtracting the
    share price from the net asset value per share and is usually expressed as a
    percentage (%) of the net asset value per share. If the share price is higher
    than the net asset value per share the result is a premium. If the share price
    is lower than the net asset value per share, the shares are trading at a
    discount.

    Equity Swaps

    An equity swap is an agreement in which one party (counterparty) transfers the
    total return of an underlying equity position to the other party (swap holder)
    in exchange for a one off payment at a set date. Total return includes dividend
    income and gains or losses from market movements. The exposure of the holder is
    the market value of the underlying equity position.

    Your Company uses two types of equity swap:

    -       funded, where payment is made on acquisition. They are equivalent to
    holding the underlying equity position with the exception of additional
    counterparty risk and not possessing voting rights in the underlying; and,

    -       financed, where payment is made on maturity. As there is no initial
    outlay, financed swaps increase economic exposure by the value of the
    underlying equity position with no initial increase in the investments value -
    there is therefore embedded leverage within a financed swap due to the deferral
    of payment to maturity.

    Gearing

    Gearing is calculated as borrowings, less net current assets, divided by
    Shareholders' Funds, expressed as a percentage.

    Leverage

    Leverage is defined in the AIFMD as any method by which the AIFM increases the
    exposure of an AIF. Therefore, the Company has to comply with the AIFMD
    leverage requirements. For these purposes the Board has set a maximum leverage
    limit of 40% for both methods. Under AIFMD this limit is expressed as 140%,
    where 100% represents no leverage or gearing in the Company. There are two
    methods of calculating leverage as follows:

    The Gross Method is calculated as total exposure divided by Shareholders Funds.
    Total exposure is calculated as net assets, less cash and cash equivalents,
    adding back cash borrowing plus derivatives converted into the equivalent
    position in their underlying assets.

    The Commitment Method is calculated as total exposure divided by Shareholders
    Funds. In this instance total exposure is calculated as net assets, less cash
    and cash equivalents, adding back cash borrowing plus derivatives converted
    into the equivalent position in their underlying assets, adjusted for netting
    and hedging arrangements.

    See the definition of Options and Equity Swaps for more details on how exposure
    through derivatives is calculated.

    NAV Total Return

    The theoretical total return on shareholders' funds per share, including the
    assumed £100 original investment at the beginning of the period specified,
    reflecting the change in NAV assuming that dividends paid to shareholders were
    reinvested at NAV at the time the shares were quoted ex-dividend. A way of
    measuring investment management performance of investment trusts which is not
    affected by movements in discounts/premiums.

    Ongoing Charges

    Ongoing charges are calculated by taking the Company's annualised ongoing
    charges, excluding finance costs, taxation, performance fees and exceptional
    items, and expressing them as a percentage of the average daily net asset value
    of the Company over the year.

    Options

    An option is an agreement that gives the buyer, who pays a fee (premium), the
    right - but not the obligation - to buy or sell a specified amount of an
    underlying asset at an agreed price (strike or exercise price) on or until the
    expiration of the contract (expiry). A call option is an option to buy, and a
    put option an option to sell.

    The potential loss of the buyer is limited to the higher of the premium paid or
    the market value of the bought option. On the other side for the seller of a
    covered call option (your company does not sell uncovered options) any loss
    would be offset by gains in the covering position, and for sold puts the
    potential loss is the strike price times the number of option contracts held.
    The exposure, used in calculating the AIFMD leverage limits, is determined as
    the delta (an options delta measures the sensitivity of an option's price
    solely to a change in the price of the underlying asset) adjusted equivalent of
    the underlying position.

    Performance Fee

    Dependent on the level of long-term outperformance of the Company, a
    performance fee can be become payable. The performance fee is calculated by
    reference to the amount by which the Company's net asset value ('NAV')
    performance has outperformed the Benchmark.

    The fee is calculated quarterly by comparing the cumulative performance of the
    Company's NAV with the cumulative performance of the Benchmark since the launch
    of the Company in 1995. Provision is also made within the daily NAV per share
    calculation as required and in accordance with generally accepted accounting
    standards. Up to 31 March 2017, the performance fee amounted to 16.5% of any
    outperformance over the Benchmark, the Portfolio Manager receiving 15% and the
    AIFM receiving 1.5%, respectively. With effect from 1 April 2017 the Company's
    AIFM no longer receives a performance fee (see page 27 and also page 28 of the
    Company's Annual Report & Accounts for the year ended 31 March 2017 for further
    information).

    In order to ensure that only sustained outperformance is rewarded, at each
    quarterly calculation date any performance fee payable is based on the lower
    of:

    i)       The cumulative outperformance of the investment portfolio over the
    Benchmark as at the quarter end date; and

    ii)      The cumulative outperformance of the investment portfolio over the
    Benchmark as at the corresponding quarter end date in the previous year.

    The effect of this is that outperformance has to be maintained for a twelve
    month period before the related fee is paid.

    In addition, a performance fee only becomes payable to the extent that the
    cumulative outperformance gives rise to a total fee greater than the total of
    all performance fees paid to date.
