The following table sets forth UBS AG’s ratio of earnings to fixed charges on an IFRS basis for the periods indicated. The ratios are calculated based on earnings from continuing operations.

	For the quarter ended	For the year ended
CHF million, except for ratio	30.9.18	31.12.17	31.12.16	31.12.15¹	31.12.14	31.12.13
Pre-tax earnings from continuing operations	1,528	4,977	4,009	5,349	2,424	3,287

Total fixed charges	2,651	7,865	7,998	7,153	7,293	8,030

Ratio of earnings to fixed charges³	1.58	1.63	1.50	1.75	1.33	1.41
1 Upon adoption of the amendments to IAS 1 on 1 January 2018, UBS AG presents interest income and expense from financial instruments measured at amortized cost and fair value through other comprehensive income separately from interest income and expense from financial instruments measured at fair value through profit or loss. Prior periods were amended for this change in presentation. As a consequence, interest expense for the year ended 31 December 2015 increased by CHF 101 million, which resulted in a reduction of the ratio of earnings to fixed charges from 1.76 to 1.75. All other periods presented were not affected by this change in presentation. 2 Other fixed charges relate to the estimated interest component of rental expense. 3 UBS AG redeemed its last outstanding preferred notes in December 2017. A ratio of earnings to combined fixed charges and preference security dividends was not presented for periods prior to 2018 as there were no mandatory preferred share dividends in these periods. Accordingly, the ratio would have equaled the ratio of earnings to fixed charges.

This Form 6-K is hereby incorporated by reference into (1) each of the registration statements of UBS AG on Form F-3 (Registration Number 333-225551) and of UBS Group AG on Form S-8 (Registration Numbers 333-200634; 333-200635; 333-200641; 333-200665; 333-215254; and 333-215255) and into each prospectus outstanding under any of the foregoing registration statements, (2) any outstanding offering circular or similar document issued or authorized by UBS AG that incorporates by reference any Form 6-K’s of UBS AG that are incorporated into its registration statements filed with the SEC, and (3) the base prospectus of Corporate Asset Backed Corporation (“CABCO”) dated June 23, 2004 (Registration Number 333-111572), the Form 8-K of CABCO filed and dated June 23, 2004 (SEC File Number 001-13444), and the Prospectus Supplements relating to the CABCO Series 2004-101 Trust dated May 10, 2004 and May 17, 2004 (Registration Number 033-91744 and 033-91744-05).
