KEY RATING DRIVERS
Firm Asset Performance
Fitch has revised its base case charge-off expectation to 7.0% from 7.5% for the Penarth trust, which is at the median of the range of 4.5% to 8.0% assigned in similar transactions. The agency's base case assumptions for the trust's monthly payment rate (18%) and yield rate (16%) remain unchanged since the most recent issuance in October 2014.

Originator Linkage
Due to the revolving nature of the underlying assets, relative to the amortising receivables, asset performance is closely linked to the performance of the originator. Fitch conducted an annual review of the underwriting and servicing processes at BoS and Lloyds in December 2014 and found both the policies and procedures satisfactory, as were implementation and controls.

Interchange Cap Impact
Fitch has expected regulatory pressure on interchange fees for some time and therefore has not given full credit to interchange revenue when setting its base case yield assumption, as denoted in its Credit Card ABS Rating Criteria and previous reports. EU regulation, as confirmed by a ruling of the European Court of Justice in September 2014, has reduced the cap on interchange fees to 0.3% (the current UK average is 0.9%) of transacted amounts and is due to come into force from 3Q15 in the UK. No additional yield stress was applied in the analysis, as the impact of the cap will also depend on any second-order effects on cardholder composition, payment behaviour and any countermeasures originators might implement. Fitch will continue to assess any downward pressure on yield as a result of regulatory and competitive forces.

US Dollar Swap Counterparty
The 2015-1 A1 notes are denominated in US dollars, while the credit card receivables are denominated in sterling. To hedge the currency risk, the issuer entered into a cross-currency swap with Wells Fargo Bank. As a US entity, Fitch does not consider the subordination clause for swap termination payments to be enforceable should Wells Fargo Bank default. This corresponds to the minimum rating eligibility (BBB+/F2) for the swap counterparty under Fitch's criteria. Further mitigating factors in line with Fitch's criteria address counterparty risk.

Stable Asset Outlook
The performance of credit card trusts continued to improve throughout 1Q15, with charge-off, delinquency and payment rates improving, while yield rates declined over the same period.

Fitch revised its GDP growth forecast to 2.5% from 2.6% for 2015 and maintained the forecast of 2.3% for 2016 in its March Global Economic Outlook. The agency believes annual UK unemployment rates for 2015 and 2016 will stay stable and eventually drop from 5.6% forecast for 2015 to 5.5% in 2016. Fitch therefore maintains its stable outlook for UK credit card debt.
