1 Effective 1 January 2011, the Swiss withholding tax law provides that payments out of the capital contribution reserve are not subject to withholding tax. This law has led to interpretational differences between the Swiss Federal Tax Administration and companies about the qualifying amounts of capital contribution reserve and the disclosure in the financial statements. In view of this, the Swiss Federal Tax Administration has confirmed that UBS AG would be able to repay to shareholders CHF 23.0 billion of disclosed capital contribution reserve without being subject to the withholding tax deduction that applies to dividends paid out of retained earnings. The confirmation by the Swiss Tax Administration was dated 1 January 2016. This amount decreased by CHF 2.5 billion as of 31 December 2017 subsequent to distributions in 2017. The decision about the remaining amount has been deferred to a future point in time.    2 Cash to be paid in the future by either UBS AG or the counterparty.

Off-balance sheet items

Off-balance sheet items include indemnities and guarantees issued by UBS AG for the benefit of subsidiaries and creditors of subsidiaries.

Where the indemnity amount issued by UBS AG is not specifically defined, the indemnity relates to the solvency or minimum capitalization of a subsidiary, and therefore no amount is included in the table above.

Joint and several liability – Value added tax (VAT)

UBS AG is jointly and severally liable for the combined VAT liability of UBS entities that belong to the VAT group of UBS in Switzerland. This contingent liability is not included in the table above.

Guarantee – UBS Limited

UBS AG has issued a guarantee for the benefit of each counterparty of UBS Limited. Under this guarantee, UBS AG irrevocably and unconditionally guarantees each and every obligation that UBS Limited enters into. UBS AG promises to pay to that counterparty on demand any unpaid balance of such liabilities under the terms of the guarantee.

Indemnities – UBS Europe SE

In connection with the establishment of UBS Europe SE in 2016, UBS AG entered into an agreement with UBS Europe SE under which UBS AG would provide UBS Europe SE with limited indemnification of payment obligations that may arise from certain litigation, regulatory and similar matters.

As of 31 December 2017, the amount of such potential payment obligations could not be reliably estimated and the table above does therefore not include any amount related to this limited indemnification.

In addition, in accordance with the bylaws of the Deposit Protection Fund of the Association of German Banks, UBS AG issued on behalf of UBS Europe SE an indemnity in favor of this fund. The probability of an outflow was assessed to be remote, and as a result, the table above does not include any exposure arising under this indemnity.

Joint and several liability – UBS Switzerland AG

In June 2015, the Personal & Corporate Banking and Wealth Management businesses booked in Switzerland were transferred from UBS AG to UBS Switzerland AG through an asset transfer in accordance with the Swiss Merger Act. Under the Swiss Merger Act, UBS AG assumed joint liability for obligations existing on the asset transfer date, 14 June 2015, that were transferred to UBS Switzerland AG, excluding the collateralized portion of secured contractual obligations.

As of the asset transfer date, this joint liability amounted to approximately CHF 260 billion. UBS AG has no liability for new obligations incurred by UBS Switzerland AG after the asset transfer date. The joint liability amount declines as obligations mature, terminate or are novated following the asset transfer date.

As of 31 December 2017, the joint liability of UBS AG for contractual obligations of UBS Switzerland AG amounted to less than CHF 1 billion, unchanged from 31 December 2016. As of 31 December 2017, the probability of an outflow under this joint and several liability was assessed to be remote, and as a result, the table above does not include any exposures arising under this joint and several liability.

Major differences between the Swiss GAAP requirements and International Financial Reporting Standards are described in Note 36 to the consolidated financial statements of UBS AG. The significant accounting policies applied for the standalone financial statements of UBS AG are discussed below.

®Refer to the UBS Group AG and UBS AG Annual Report 2017 for more information

Note 2  Accounting policies (continued)

Structured debt instruments

Structured debt instruments comprise structured debt instruments issued and transacted over-the-counter and include a host contract and one or more embedded derivatives that do not relate to UBS AG’s own equity. By applying the fair value option, the vast majority of structured debt instruments are measured at fair value as a whole and recognized in Financial liabilities designated at fair value. The fair value option for structured debt instruments can be applied only if the following criteria are cumulatively met:

–the structured debt instrument is measured on a fair value basis and is subject to risk management that is equivalent to risk management for trading activities;

–the application of the fair value option eliminates or significantly reduces an accounting mismatch that would otherwise arise; and

–changes in fair value attributable to changes in unrealized own credit are not recognized.

Fair value changes related to Financial liabilities designated at fair value, excluding changes in unrealized own credit, are recognized in Net trading income. Interest expense on Financial liabilities designated at fair value is recognized in Interest expense.

Where the designation criteria for the fair value option are not met, the embedded derivatives are assessed for bifurcation for measurement purposes. Bifurcated embedded derivatives are measured at fair value through profit or loss and presented in the same balance sheet line as the host contract.

®Refer to Note 19 for more information

Group-internal funding

UBS AG obtains funding from UBS Group AG and UBS Group Funding (Switzerland) AG in the form of loans that qualify as going concern additional tier 1 capital at the UBS AG consolidated and standalone levels and as gone concern loss-absorbing capacity at the UBS AG consolidated level. A portion of Group-internal funding obtained is further on-lent by UBS AG to certain subsidiaries in the form of loans.

Where such Group-internal funding is eligible to meet the requirements for total loss-absorbing capacity (TLAC) at the level of UBS AG consolidated or standalone, or at the levels of significant regulated subsidiaries as defined for Pillar 3 disclosure purposes, the aggregate amounts of the respective obligations and claims are separately disclosed on the balance sheet. For those TLAC instruments that are eligible to meet the going concern capital requirements, i.e., are subordinated and subject to mandatory conversion and / or debt waiver as explained below, the aggregate corresponding amounts are disclosed on the balance sheet.

Obligations of UBS AG arising from Group-internal funding it has received are presented as Due to customers and measured at amortized cost. Claims of UBS AG from Group-internal funding it has provided are presented as Due from banks and Due from customers and measured at amortized cost less any allowance for credit losses. Further information on the assessment and recognition of credit losses of claims is provided in Note 1 to the consolidated financial statements of UBS AG.

®Refer to the UBS Group AG and UBS AG Annual Report 2017 for more information

Subordinated assets and liabilities

Subordinated assets are comprised of claims that, based on an irrevocable written declaration, in the event of liquidation, bankruptcy or composition concerning the debtor, rank after the claims of all other creditors and may not be offset against amounts payable to the debtor nor be secured by its assets. Subordinated liabilities are comprised of corresponding obligations.

Subordinated assets and liabilities that contain a point-of-non-viability clause in accordance with Swiss capital requirements per articles 29 and 30 of the Capital Adequacy Ordinance are disclosed as being subject to mandatory conversion and / or debt waiver and provide for the claim or the obligation to be written off or converted into equity in the event that the issuing bank reaches a point of non-viability.

Investments in subsidiaries and other participations

Investments in subsidiaries and other participations are equity interests that are held to carry on the business of UBS AG or for other strategic purposes. They include all subsidiaries directly held by UBS AG through which UBS AG conducts its business on a global basis. The investments are measured individually and carried at cost less impairment. The carrying value is tested for impairment when indications for a decrease in value exist, which include incurrence of significant operating losses or a severe depreciation of the currency in which the investment is denominated. If an investment in a subsidiary is impaired, its value is generally written down to the net asset value. Subsequent recoveries in value are recognized up to the original cost value based on either the increased net asset value or a value above the net asset value if, in the opinion of management, forecasts of future profitability provide sufficient evidence that a carrying value above net asset value is supported. Management may exercise its discretion as to what extent and in which period a recovery in value is recognized.

Impairments of investments are presented as  Impairment of investments in subsidiaries and other participations. Reversals of impairments are presented as Extraordinary income in the income statement. Impairments and partial or full reversals of impairments for a subsidiary during the same annual period are determined on a net basis.

Note 2  Accounting policies (continued) 

Services received from and provided to Group entities

UBS AG receives services from UBS Business Solutions AG, the main Group service company, mainly relating to Group Technology, Group Operations and Group Corporate Services, as well as certain other services from other Group entities. UBS AG provides services to Group entities mainly relating to real estate and selected other Corporate Center – Services functions.  Services received from and provided to Group entities are settled in cash as hard cost transfers or hard revenue transfers paid or received.

When the nature of the underlying transaction between UBS AG and the Group entity contains a single, clearly identifiable service element, related income and expenses are presented in the respective income statement line item, e.g., Fee and commission income from securities and investment business and other fee and commission income, Fee and commission expense, Net trading income or General and administrative expenses.To the extent the nature of the underlying transaction contains various service elements and is not clearly attributable to a particular income statement line item, related income and expenses are presented in Sundry ordinary incomeand Sundry ordinary expenses. 

®Refer to Notes 5 and 7 for more information

Pension and other post-employment benefit plans

Swiss GAAP permits the use of IFRS or Swiss accounting standards for pension and other post-employment benefit plans, with the election made on a plan-by-plan basis.

UBS AG has elected to apply Swiss GAAP (FER 16) for the Swiss pension plan in its standalone financial statements. The requirements of Swiss GAAP are better aligned with the specific nature of Swiss pension plans, which are hybrid in that they combine elements of defined contribution and defined benefit plans, but are treated as defined benefit plans under IFRS. Swiss GAAP requires that the employer contributions to the pension fund are recognized as Personnel expenses in the income statement. The employer contributions to the Swiss pension fund are determined as a percentage of contributory compensation. Furthermore, Swiss GAAP requires an assessment as to whether, based on the financial statements of the pension fund prepared in accordance with Swiss accounting standards (FER 26), an economic benefit to, or obligation of, UBS AG arises from the pension fund and is recognized in the balance sheet when conditions are met. Conditions for recording a pension asset or liability would be met if, for example, an employer contribution reserve is available or UBS AG is required to contribute to the reduction of a pension deficit (on a FER 26 basis).

Key differences between Swiss GAAP and IFRS include the treatment of dynamic elements, such as future salary increases and future interest credits on retirement savings, which are not considered under the static method used in accordance with Swiss GAAP. Also, the discount rate used to determine the defined benefit obligation in accordance with IFRS is based on the yield of high-quality corporate bonds of the market in the respective pension plan country. The discount rate used in accordance with Swiss GAAP, i.e., the technical interest rate, is determined by the Pension Foundation Board based on the expected returns of the Board’s investment strategy.

®Refer to Note 21 for more information

UBS AG has elected to apply IFRS (IAS 19) for its non-Swiss defined benefit plans. However, remeasurements of the defined benefit obligation and the plan assets are recognized in the income statement rather than directly in equity. For corresponding disclosures in accordance with IAS 19 requirements, refer to Note 26 to the consolidated financial statements of UBS AG.

®Refer to the UBS Group AG and UBS AG Annual Report 2017 for more information

After the transfer of shared services functions to UBS Business Solutions AG as further outlined in Note 2b, UBS AG ceased to make direct contributions to the respective pension plans for transferred employees. Instead, UBS AG receives a service charge from the Group service companies including their respective pension costs, which is recognized as General and administrative expenses.  

Deferred taxes

Deferred tax assets are not recognized in UBS AG’s standalone financial statements. However, deferred tax liabilities may be recognized for taxable temporary differences. Changes in the deferred tax liability balance are recognized in the income statement.

Dispensations in the standalone financial statements

As UBS AG prepares consolidated financial statements in accordance with IFRS, UBS AG is exempt from various disclosures in the standalone financial statements. The dispensations include the management report, the statement of cash flows and various note disclosures, as well as the publication of full interim financial statements. As a Swiss issuer of debt, in order to validly issue debt throughout the year, UBS AG discloses interim mid-year financial information as per the requirements of Article 1156 in conjunction with Article 652a of the Swiss Code of Obligations, including an income statement, a balance sheet and a note on the basis of accounting.

b) Changes in accounting policies and / or comparability

Presentation of interest income and expense on derivatives designated as hedging instruments

Effective 1 January 2017, UBS AG refined the presentation of interest income and interest expense on derivatives designated as hedging instruments in effective hedge relationships to align the presentation with interest arising from designated hedged items. As a result, Interest and discount income and Interest expense for the year ended 31 December 2017 were each CHF 530 million lower, with no change to Net interest income. Prior-period information has not been restated.

Transfers of shared services functions to UBS Business Solutions AG and UBS Business Solutions US LLC

The comparative figures presented as of and for the year ended 31 December 2016 include the financial effect of shared services functions in Switzerland, the UK and the US. These functions were substantially transferred to Group service companies in 2017. The transfer in Switzerland to UBS Business Solutions AG, the main Group service company and a wholly owned subsidiary of UBS Group AG, was executed in the second quarter of 2017. For UK shared services, a similar transfer to the UK branch of UBS Business Solutions AG was completed in the fourth quarter of 2017. In the second quarter of 2017, UBS also completed the transfer of the shared services functions in the US, which started in 2016, to its US service company, UBS Business Solutions US LLC, a wholly owned subsidiary of UBS Americas Holding LLC.

The transfer in Switzerland was carried out in three steps: a transfer of the respective business from UBS AG to an interim shared services subsidiary of UBS AG in accordance with article 69ff. of the Swiss Federal Act on Mergers, Demergers, Transformations and Transfers of Assets and Liabilities (Merger Act), followed by a distribution of the shares in this interim shared services subsidiary from UBS AG to UBS Group AG through a dividend in kind, and the merger of the subsidiary with the previously established UBS Business Solutions AG.

The transfer resulted in a CHF 250 million reduction of net assets and of the capital contribution reserve.

The transferred functions include Group Technology, Group Operations, Group Corporate Services and most other shared services functions. As a consequence, UBS AG no longer incurs the respective direct costs, no longer charges other Group entities for underlying services and no longer earns a related markup, but rather receives a charge including a markup from a service company for its own consumption of services provided by the service companies. UBS AG retained the vast majority of its real estate portfolio and selected other Corporate Center – Services functions and continues to charge other Group entities for services provided to them, earning a markup.

The new shared services model resulted in a net profit reduction for UBS AG of approximately CHF 0.2 billion in the year 2017. This amount includes net decreases in Other income from ordinary activities of CHF 1.9 billion, Personnel expenses of CHF 1.3 billion, General and administrative expenses of CHF 0.3 billion and Depreciation and impairment of property, equipment and software of CHF 0.1 billion.

The transfer in Switzerland resulted in a reduction in UBS AG’s share in the Swiss pension plan surplus of CHF 2.4 billion in the year 2017.

As of 31 December 2017, shares issued by UBS AG totaled 3,858,408,466 shares (unchanged from 31 December 2016). The shares were all dividend bearing and held by UBS Group AG.

Additionally, as of 31 December 2017, 516,200,312 registered shares with a par value of CHF 0.10 each were available to be issued out of conditional capital (unchanged from 31 December 2016).

During 2017 and 2016, there were no new share issuances out of conditional capital.

Non-cash dividend

With the transfer of shared services functions in Switzerland, UBS AG transferred its participation in a service center subsidiary to UBS Group AG in June 2017 by way of distribution of a dividend in kind, which resulted in a CHF 250 million reduction in the capital contribution reserve.

®Refer to Note 2b for more information on the transfer of shared services functions

Non-distributable reserves

Non-distributable reserves consist of 50% of the share capital of UBS AG, amounting to CHF 193 million as of 31 December 2017 (unchanged from 31 December 2016).

The surplus did not represent an economic benefit for UBS AG in accordance with FER 16 both as of 31 December 2017 and 31 December 2016.

UBS AG has elected to apply FER 16 for its Swiss pension plan and IFRS (IAS 19) for its UK and other non-Swiss defined benefit plans. However, remeasurements of the defined benefit obligations for UK and other non-Swiss defined benefit plans are recognized in the income statement rather than directly in equity.

UBS AG standalone regulatory information

Swiss SRB going concern requirements and information

UBS AG standalone is considered a systemically relevant bank (SRB) under Swiss banking law and is subject to capital regulations on a standalone basis. Under Swiss SRB regulations, article 125 “Reliefs for financial groups and individual institutions” of the Capital Adequacy Ordinance stipulates that the Swiss Financial Market Supervisory Authority (FINMA) may grant, under certain conditions, capital relief to individual institutions to ensure that an individual institution’s compliance with the capital requirements does not lead to a de facto overcapitalization of the group of which it is a part.

FINMA granted relief concerning the regulatory capital requirements of UBS AG on a standalone basis by means of decrees issued on 20 December 2013 and 20 October 2017, the latter effective as of 1 July 2017 and partly replacing the former.

The FINMA decree issued in 2017 newly establishes the measure of total going concern capital for UBS AG. Common equity tier 1 (CET1) and high-trigger additional tier 1 capital instruments are eligible as going concern capital, and low-trigger tier 2 capital instruments remain eligible until the earlier of
(i) their maturity or the first call date or (ii) 31 December 2019.

Capital requirements based on risk-weighted assets (RWA) and leverage ratio denominator (LRD) are the same under both the phase-in and fully applied rules. The capital requirements based on RWA include a minimum CET1 capital requirement of 10% plus the effects from countercyclical buffers (CCBs), and a total going concern capital requirement of 14.3% plus the effects from CCBs. The capital requirements based on LRD include a minimum CET1 capital requirement of 3.5% and a total going concern leverage ratio requirement of 5.0%. Compared with the requirements set by the December 2013 FINMA decree, the total capital requirement increased 0.3 percentage points and the total leverage ratio requirement increased 1.6 percentage points. Additionally, for direct and indirect investments, including holding of regulatory capital instruments of UBS AG in subsidiaries that are active in banking and finance, the new FINMA decree abolishes the threshold deduction approach by introducing a risk-weighting approach, with a phase-in period until 1 January 2028. Starting 1 July 2017, these investments have been risk-weighted at 200%. As of 1 January 2019, the risk weights will gradually be raised by 5 percentage points per year for Swiss-domiciled investments and by 20 percentage points per year for foreign-domiciled investments until the fully applied risk weights are 250% and 400%, respectively.

More information on this change is provided in “Section 2 UBS AG standalone” of the UBS Group AG and significant regulated subsidiaries and sub-groups third quarter 2017 Pillar 3 report, available under “Pillar 3 disclosures” at www.ubs.com/investors.

Outstanding low-trigger loss-absorbing tier 2 capital instruments are subject to amortization starting five years prior to their maturity.
