Notes to the consolidated financial statements

1. The Company and its principal activity

BB Biotech AG (the Company) is listed on the SIX Swiss Exchange, in the «Prime Standard Segment» of the German Exchange as well as in the «Star Segment» of the Italian Exchange and has its registered office in Schaffhausen, Schwertstrasse 6. Its principal activity is to invest in companies active in the biotechnology industry for the purpose of capital appreciation. The investments are held through its wholly owned subsidiaries. 

2. Accounting policies

General

The consolidated financial statements of the Company and its subsidiary companies (the Group) have been prepared in accordance with International Financial Reporting Standards (IFRS), as well as the provisions of the rules of the SIX Swiss Exchange for Investment Companies for the period January 1, 2020, until December 31, 2020. The consolidation is prepared from the financial statements of the Group companies using uniform accounting principles. With the exception of financial assets and liabilities (incl. derivative instruments), which are held at fair value through profit or loss, the financial statements are prepared under the historical cost convention. This requires management to make assumptions and estimates that have an impact on the balance sheet values and items of the income statement in the current financial year. In certain circumstances, the actual values may differ from these estimates.

The following amended standards, valid since January 1, 2020, have been applied in these annual consolidated financial statements:

• IAS 1, IAS 8 (amended, effective January 1, 2020) – Definition of Material
• IFRS 3 (amended, effective January 1, 2020) – Business Combinations
• IAS 39, IFRS 7, IFRS 9 (amended, effective January 1, 2020) – IBOR-Reform

The Group assessed the impact of the above-mentioned amended standards. Based on the analysis, the Group concludes that these amended standards have no material impact on the Group’s accounting policies and overall results and financial position.

The following amended standards were approved, but will only be applicable for the Group prospectively and were not early adopted in these annual consolidated financial statements:

• IAS 1 (amended, effective January 1, 2022) – Classification of Liabilities as Current or Non-current
• IFRS 3 (amended, effective January 1, 2022) – Reference to the Conceptual Framework
• IAS 37 (amended, effective January 1, 2022) – Onerous Contracts – Cost of fulfilling a Contract
• Annual Improvements to IFRS Standards 2018-2020 (effective January 1, 2022) – IFRS 9, IFRS 16

The Group assessed the potential impact of the above-mentioned amended standards. Based on the analysis, the Group concludes that these amended standards have no material impact on the Group’s accounting policies and overall results and financial position.

Basis of consolidation

The consolidated financial statements include the Company and the subsidiary companies which are controlled by it. An investor controls an investee when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Subsidiaries are fully consolidated from the date on which control is transferred to the Company and are deconsolidated from the date that control ceases. The consolidation is performed using the acquisition method. All intercompany transactions and balances with companies included in the consolidation are eliminated. All Group companies have a December 31 year-end.

Foreign currency translation

Based on the economic environment (primary listing, investors, costs and performance measurement) in which the Company and its subsidiaries operate, the consolidated financial statements of the Group are presented in Swiss francs, which is the Company’s and its subsidiaries functional currency. Transactions in foreign currencies are converted at exchange rates as at transaction dates. Assets and liabilities in foreign currencies at year-end are translated at rates of exchange prevailing as at the balance sheet date. Exchange differences are reflected in the statement of income. Translation differences on marketable securities held at fair value through profit or loss are reported as part of the net gains/(losses) from securities.

The following exchange rates have been used for the preparation of these consolidated financial statements:

Financial assets

The Group classifies its financial assets in the following categories:

• Financial assets at amortized cost
• Financial assets at fair value through profit or loss

Financial assets at amortized cost

Financial assets at amortized cost are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They are included in current assets, except when they have maturities of greater than twelve months after the balance sheet date. Otherwise they are classified as non-current assets.

Cash and cash equivalents

Cash and cash equivalents comprise current accounts and call money at banks which have a maturity of three months or less.

Receivables from brokers

Receivables from brokers result from security transactions and do not bear any interest.

These amounts are recognized initially at fair value and subsequently measured at amortized cost. At each reporting date, the Group shall measure the loss allowance on amounts due from broker at an amount equal to the Lifetime Expected Credit Loss («ECL») if the credit risk has increased significantly since initial recognition. If, at the reporting date, the credit risk has not increased significantly since initial recognition, the Group shall measure the loss allowance at an amount equal to 12-month ECLs. A significant increase in credit risk is defined as any contractual payment which is more than 30 days past due. Any contractual payment which is more than 90 days past due is considered credit impaired. For receivables from brokers which settle within 10 business days the ECL estimate is nil.

Financial assets at fair value through profit or loss

Financial assets at fair value through profit or loss comprise marketable and non-marketable securities which are classified as current assets.

Initially, securities and derivatives are measured at fair value and are subsequently remeasured at market values based on stock exchange prices or generally accepted valuation models that are based on market conditions existing at each balance sheet date, such as Black- Scholes, earnings multiple and discounted cash flow model. Purchases and sales of securities are accounted for at trade date. Realized gains and losses on security trading are recognized in the statement of comprehensive income as net gains/losses from securities at the day of the transaction. Changes in fair value of securities are also recognized as net gains/losses from securities in the statement of comprehensive income in the same period in which they arise. Securities are derecognized when the rights to receive cash flows from securities have expired or where the Group has transferred substantially all risks and rewards of ownership.

Transaction costs are costs to acquire financial assets at fair value through profit or loss. They include transfer taxes and duties as well as fees and commissions paid to agents, advisers, brokers and dealers. Transaction costs, when incurred, are immediately recognized as an expense.

Financial liabilities

Financial liabilities are generally classified and subsequently measured at amortized cost using the effective interest method, except for financial liabilities held for trading and derivatives.

Payables to brokers

Payables to brokers result from security transactions and do not bear any interest.

Short-term borrowings from banks

Short-term borrowings are recognized initially at fair value, net of transaction costs incurred. Borrowings are subsequently stated at amortized cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized in the income statement over the period of the borrowings using the effective interest method. Borrowings are classified as current liabilities unless the Group has an unconditional right to defer settlement of the liability for at least twelve months after the balance sheet date.

Income taxes

Current income taxes are calculated on the basis of the applicable tax laws in individual countries and recognized as an expense in the period in which the related profits are made.

Assets or liabilities related to current income taxes are reported in the balance sheet in the items «Current tax assets» or «Current tax liabilities ». Tax effects arising from temporary differences between the carrying amounts of assets and liabilities in the Group’s balance sheet and their corresponding tax values are recognized, respectively, as «Deferred tax assets» and «Deferred tax liabilities». Deferred tax assets arising from temporary differences and from loss carry-forwards eligible for offset are capitalized if it is likely that sufficient taxable profits will be available against which those temporary differences or loss carry-forwards can be offset. Deferred tax assets and deferred tax liabilities are calculated at the tax rates expected to apply in the period in which the tax assets will be realized, or the tax liabilities settled.

Earnings per share

Basic earnings per share are calculated by dividing the net profit/loss attributable to shareholders by the weighted average number of registered shares in issue during the year, less treasury shares. For the diluted earnings per share, the weighted average number of registered shares in issue and the net profit is adjusted to assume conversion of all dilution potential registered shares.

Treasury shares

The company can buy and sell treasury shares in accordance with the Company’s article of association, Swiss company law and in compliance with the listing rules of SIX Swiss Exchange.

Treasury shares are recorded as a deduction from the shareholders’ equity at the amount of considerations paid («Total cost»). All gains and losses arising from trading in treasury shares are directly credited/debited to retained earnings. The FIFO (first in/first out) method is used for derecognition. The purchase price is booked gross with transaction costs. Treasury shares may be acquired and held by the Company or by other members of the consolidated Group.

Net asset value per share

The net asset value per share is calculated by dividing the shareholders’ equity by the number of shares outstanding less treasury shares held at year end.

Dividend income

Dividends on securities are recognized in the income statement when the Group’s right to receive payment is established.

Leasing contracts

The Group has two rental contracts for office space in Schaffhausen and Curacao. Due to the immateriality of a right-of-use-asset and a lease liability, no disclosure according to IFRS 16 are made within these consolidated financial statements.

Pension liability

BB Biotech AG maintains for its employee a defined benefit plan. There is no pension plan for employees of Group companies. Due to the immateriality of any potential pension liability or potential pension asset, no disclosures according to IAS 19 are made within these consolidated financial statements.

Segment reporting

IFRS 8 requires entities to define operating segments and segment performance in the financial statements based on information used by the chief operating decision-maker. The investment manager is considered to be the chief operating decision-maker. An operating segment is a group of assets and operations engaged in providing products or services that are subject to risks and returns that are different from those of other operating segments. The sole operating segment of the Group is investing in companies active in the biotechnology industry. The investment manager works as a team for the entire portfolio, asset allocation is based on a single, integrated investment strategy and the Group’s performance is evaluated on an overall basis. Thus the results published in this report correspond to the sole operating segment of investing in companies active in the biotechnology industry.

Related party

Related parties are individuals and companies where the individual or company has the ability, directly or indirectly, to control the other party or to exercise significant influence over the other party in making financial and operating decisions.

Commitments, contingencies and other off-balance sheet transactions

The operations of the Group are affected by legislative, fiscal and regulatory developments for which provisions are made where a legal or constructive obligation has been incurred which will probably lead to an outflow of resources that can be reasonably estimated.

Critical accounting estimates and judgments

The fair value of financial instruments that are not traded in an active market is determined by using valuation techniques. The Group makes estimates and assumptions that are mainly based on market conditions to value these financial instruments. Since these financial instruments are not traded in an active market, inherent difficulties exist to value these financial instruments. These difficulties cannot be eliminated. The difference between the proceeds from sale of these financial instruments and the carrying amount may be material.

The Company has assessed whether it is appropriate under IFRS 10 to consolidate the Subsidiaries. IFRS 10 states that an investor controls the investee if, and only if, the investor has all of the following:

• Power over the investee;
• Exposure, or rights, to variable returns from its involvement with the investee; and
• The ability to use its power over the investee to affect the amount of the investor's returns

The Company owns 100%  of the capital and voting interest in all four subsidiaries as disclosed in note 1. Therefore the Company has power over the organization and directs the investment activities and dividend policy of its subsidiaries. The scope of the investment management and administration agreement with the investment manager also includes all subsidiaries.

Further, IFRS 10 requires that a subsidiary that provides services related to the parent’s investment activities should not be consolidated if the subsidiary itself is an investment entity. The Company also made an assessment as to whether the Company’s Subsidiaries meet the definition of an investment entity. IFRS 10 provides that an investment entity should have the following typical characteristics:

• It has more than one investment;
• It has more than one investor;
• It has investors that are not related parties of the entity; and
• It has ownership interests in the form of equity or similar interests.

An investment entity is still required to consolidate its subsidiaries if the subsidiary provides services that relate to the investment entity’s investment activities.

The Company concluded that the Subsidiaries do not qualify as investment entities, but are effectively operating subsidiaries as they act as an extension of the Company. They provide requisite investment-related services to the Company and incur costs in doing so, thus the Company consolidates its ssubsidiaries. Fair value accounting would not have a material impact on the net income and equity of the Group.

3. Financial risk management

Within the framework of the law, articles of incorporation and regulations, the investment manager carries out currency and security forward transactions, buys, sells and makes use of options as well as fulfills all necessary obligations that result from these businesses.

Credit risk

The Group is exposed to credit risk, which is the risk that a counterparty will be unable to pay amount in full when due. The Group measures credit risk and expected credit losses using probability of default, exposure at default and loss given default. The Group considers both historical analysis and forward looking information in determining any expected credit loss.

The Group manages and controls its credit risk by maintaining business relations only with counterparties with an acceptable credit rating. All transactions in securities are settled/paid for upon delivery using approved brokers. The risk of default is considered minimal, as delivery of securities sold is only made once the broker has received payment. Payment is made on a purchase once the securities have been received by the broker. The trade will fail if either party fails to meet its obligation. The Group’s credit positions, if any, are monitored on a daily basis by the investment manager and are reviewed on a regular basis by the Board of Directors.

As at December 31, 2020 and 2019, the ECL-impairment model did not have a material impact as (i) the majority of the financial assets are measured at fair value through profit or loss and the impairment requirements do not apply to such instruments; and (ii) the financial assets at amortized cost are short-term (no longer than 10 days). As a result, no loss allowance has been recognized.

Market risks

Risk associated with changing market prices

Due to its business activity and the resulting high portion of securities in relation to total assets, the Group is exposed to market price risk arising from uncertainties and fluctuations on the financial and foreign exchange markets.

The Group participates occassionaly, but to a substantial extent, in the capital of its investments. In the case of sales of large parts of these investments, it may be able to influence the market price. The Group’s securities positions are monitored on a daily basis by the investment manager and are reviewed on a regular basis by the Board of Directors.

The annual volatility of registered shares BB Biotech AG (reference volatility for the marketable securities) for 2020 is 33.78% (2019: 21.37%). At December 31, 2020, had the value of listed securities increased or decreased by 33.78% (2019: 21.37%) with all other variables held constant, the increase or decrease respectively in net income/loss as well as shareholders’ equity would amount to CHF 1 335.2 mn (2019: CHF 752.5 mn).

At December 31, 2020 and 2019 the Company holds no unlisted shares.

Interest risk

Interest rates on liquid funds are based on market rates. The funds are due on demand.

Short-term borrowings from banks are on current and short-term loan accounts with interest, based at market rates. Due to the high level of own funds, the effect of interest payable on the statement of income is insignificant. The majority of the Group’s securities are non-interest bearing; as a result, the Group is not subject to significant amounts of risk due to fluctuations in the prevailing levels of market interest rates.

The Group’s interest sensitivity is monitored on a daily basis by the investment manager and reviewed on a regular basis by the Board of Directors.

Currency risk

The Group hold assets denominated in currencies other than the Swiss franc, the functional currency. They are therefore exposed to currency risk, as the value of the securities denominated in other currencies will fluctuate due to changes in exchange rates. Depending on the market situation the Group could use foreign currency options and/or forward contracts to reduce the currency risk.

The following table summarizes the Group’s exposure to currency risks:

The Group’s currency position is monitored on a daily basis by the investment manager and is reviewed on a regular basis by the Board of Directors.

Liquidity risk

The Group invests the majority of its assets in investments that are traded in an active market and can be readily disposed of. The Group’s treasury shares, with the exception of shares purchased under a share buy-back program, are considered readily realizable as they are listed on three stock exchanges. The Group can invest a minor part of its portfolio in securities, which are not traded on a stock exchange and may be illiquid. As a result, the Group may not be able to liquidate its investments in these instruments on short notice. In addition, the Group has access to a credit line (notes 5 and 13).

The tables below analyze the Group’s financial liabilities into relevant maturity groupings based on the period between the balance sheet date and the contractual maturity date (in CHF 1 000):

The Group’s liquidity position is monitored on a daily basis by the investment manager and is reviewed on a regular basis by the Board of Directors.

Diversification

The investment portfolio usually consists of 20 to 35 investments. This includes five to eight large core investments, defined as positions > 5%. These investments together will account for up to two-thirds of the portfolio. Companies without a stock market listing shall not exceed 10% of the portfolio.

As at December 31, 2020, the Group held five core investments, representing 35% (2019: seven core investments, 55%) of the portfolio. The portfolio is – in line with the strategy – concentrated on a limited number of investments. Risk diversification is therefore limited.

Fair values

The following table presents the Group’s assets that are measured at fair value at December 31 (in CHF 1 000):

The fair value of financial instruments traded in active markets is based on quoted market prices at the balance sheet date. A market is regarded as active if quoted prices are readily and regularly available and those prices represent actual and regularly occurring market transactions on an arm’s length basis. The quoted market price used for financial assets held by the Group is the closing price. These instruments are included in level 1.

The fair value of financial instruments that are not traded in an active market is determined by using valuation techniques. These valuation techniques maximize the use of observable market data where it is available. The options are valued on the basis of the Black-Scholes model which is based on market conditions existing at each balance sheet date. These instruments are included in level 2.

If one or more of the significant inputs is not based on observable market data, the instrument is included in level 3. The valuation of level 3 instruments is quarterly reviewed. As soon as new or adjusted parameters are available the valuation model (e.g. earnings multiple model) of unlisted shares is adjusted accordingly. As of December 31, 2020, the Company holds one level 3 instrument, allocated as part of a corporate action on October 24, 2019 (December 31, 2019: identical).

The table below summarizes the transactions in level 3 instruments (in CHF 1 000):

There have been no transfers between level 1, 2 and 3 during the reporting period. No sensitivity analysis has been disclosed due to the immaterial amount of level 3 instruments.

For assets and liabilities carried at amortized cost, their carrying values are a reasonable approximation of fair value.

As at December 31, 2020, the Company held in total 114 662 treasury shares (December 31, 2019: nil). These treasury shares are treated as a deduction from the consolidated shareholders’ equity using cost values of TCHF 8 240 (December 31, 2019: TCHF nil).

Share buyback 2nd line (bought for cancellation)

The General Shareholders’ Meeting held on March 17, 2016, has approved a share buy-back program, whereby up to 5 540 000 shares may be repurchased by the Company. Until the end of the program, at April 11, 2019, no shares had been repurchased under this share buy-back program.

The Board of Directors has approved the repurchase of a maximum of 5 540 000 own registered shares with a nominal value of CHF 0.20 each. The share buy-back program will run from April 12, 2019, until April 11, 2022, at the latest. Until December 31, 2020, no shares had been repurchased under this share buy-back program. A repurchase would take place via second trading line for the purpose of a subsequent capital reduction.

The remuneration model of BB Biotech AG is determined by the Board of Directors. 

Since 2014, the remuneration paid to the investment manager is based upon a 1.1% p.a. all-in fee on the average market capitalization without any additional fixed or performance-based elements of compensation, which is paid on a monthly basis. The compensation of the Board of Directors consists since 2014 of a fixed compensation.

9. Other expenses

Other expenses comprise the following:

10. Taxes

(in CHF 1 000)

In the current year, the average effective income tax rate on a consolidated basis was less than 1% (2019: <1%). This low rate is mainly attributable to the fact that a large proportion of operating income was generated by companies located in Curaçao. As at December 31, 2020, there is no nettable loss carry forward (2019: none). 

11. Earnings per share

(in CHF 1 000) 

12. Segment reporting
