¹ The total assets for columns (d), (e) and (f) are reported by reference to each issuance by the issuing entity, Holmes Master Issuer PLC, as this is not a stand-alone securitisation (but a master trust). Accordingly, information as to assets that were the subject of demand and repurchased for this quarterly period is shown in row (9) in respect of the issuing entity. For each row, per issuance, the total assets and outstanding principal balances of assets in the pool are reported. Row (9) for columns (d), (e) and (f) also shows the number of total assets in the entire asset pool backing the issuances by Holmes Master Issuer PLC as at June 30, 2019 for the purpose of calculating the percentages of the repurchases for the second quarterly reporting period.

² The assets that were subject to repurchase as a result of breaches of representations and warranties in relation to asset-backed securities issued by Holmes Master Issuer PLC are shown in row (9) for columns (g) to (x).

³ The total principal balance for these assets is originally stated in pounds sterling (GBP), being the underlying currency of the assets. For the purpose of this filing, the original sterling amount has been converted to US Dollars using historic exchange rates for GBP to USD conversions as provided by Bloomberg for the relevant reference date. For the amounts provided for issuances of asset-backed securities by Holmes Master Issuer PLC, the relevant reference date for the exchange rate is the portfolio cut-off date stated in column (a). For the amounts provided as at the end of the quarter in row (9), the relevant reference date for the exchange rate is the quarterly period end date stated in column (a). If, in each case, the relevant reference date did not fall on a London business day, the exchange rate provided by Bloomberg for the next following London business day is used; unless such London business day fell in another calendar month, in which case the exchange rate provided by Bloomberg for the immediately preceding London business day is used.

⁴ These are residential mortgage loans secured over properties located in England, Wales and Scotland.

⁵ The numbers of loan accounts and total balances stated for columns (d) and (e) for all issuances by Holmes Master Issuer PLC are stated as at a portfolio cut-off date for each such issuance. The portfolio cut-off date is the relevant reference date for the statistical information on the portfolio included in the offering document for each issuance.
