This Form 6-K consists of the UBS Group AG (consolidated) BIS Basel III leverage ratio information as of 31 December 2015, published today by the registrants, which appears immediately following this page.

UBS Group AG (consolidated) regulatory information

This document contains information as of 31 December 2015 related to BIS leverage ratio and liquidity coverage ratio, as required by the revised FINMA Circular 2008 / 22 “Disclosure – banks.” Information in this document is supplementary to information provided in our Annual Report 2015.

BIS leverage ratio disclosure requirements

On 1 January 2015, disclosure requirements for the leverage ratio in accordance with BIS Basel III regulations came into effect in Switzerland, and we are required to disclose BIS leverage ratio information on a quarterly basis.

The tables in the following section provide BIS leverage ratio information as of 31 December 2015 according to the current disclosure requirements.

The BIS leverage ratio is calculated by dividing the period-end tier 1 capital by the period-end BIS leverage ratio denominator (LRD). The BIS LRD consists of IFRS on-balance sheet assets and off-balance sheet items. Derivative exposures are adjusted for a number of items, including replacement value and eligible cash variation margin netting, the current exposure method add-on and net notional amounts for written credit derivatives. Moreover, the BIS LRD includes an additional charge for counterparty credit risk related to securities financing transactions.

The table “Reconciliation of IFRS total assets to BIS Basel III total on-balance sheet exposures excluding derivatives and securities financing transactions” below shows the difference between total IFRS assets per IFRS consolidation scope and the BIS total on-balance sheet exposures, which are the starting point for calculating the BIS LRD as shown in the “BIS Basel III leverage ratio common disclosure” table on the next page. The difference is due to the application of the regulatory scope of consolidation for the purpose of the BIS calculation. In addition, carrying values for derivative financial instruments and securities financing transactions are deducted from IFRS total assets. They are measured differently under BIS leverage ratio rules and are therefore added back in separate exposure line items in the “BIS Basel III leverage ratio common disclosure” table on the next page.

® Refer to the “Capital management” section of our Annual Report 2015 for information on our Swiss SRB leverage ratio as of 31 December 2015

® Refer to the “UBS Group AG consolidated supplemental disclosures required under Basel III Pillar 3 regulations” section of our Annual Report 2015 for more information on the regulatory scope of consolidation

BIS leverage ratio

As of 31 December 2015, our BIS leverage ratio was 4.0% on a fully applied basis and 4.9% on a phase-in basis. The BIS LRD was CHF 898 billion on a fully applied basis and CHF 904 billion on a phase-in basis.

Liquidity coverage ratio

FINMA and Basel III rules require disclosure of the liquidity coverage ratio (LCR). As a Swiss SRB, we must maintain an LCR of at least 100% since 1 January 2015 and disclose LCR information on a quarterly basis. As of 31 December 2015, our three-month average total LCR was 124% compared with 121% as of 30 September 2015.

The total weighted liquidity value of high-quality liquid assets (HQLA) increased by CHF 18 billion to CHF 208 billion, mainly driven by an increase in cash and balances with central banks and securities received as collateral. Expected net cash outflows increased by CHF 10 billion to CHF 167 billion, mainly driven by higher exposures from committed credit and liquidity facilities, partially offset by reduced secured wholesale funding outflows.

® Refer to the “Treasury management” section of our Annual Report 2015 for more information on high-quality liquid assets and our liquidity coverage ratio
