The application of MIPRU 4.2F.30 R may be illustrated by an example. If a firm has a mortgage exposure of £100,000 secured on residential property in the United Kingdom that satisfies the criteria listed in MIPRU 4.2F.4 R to MIPRU 4.2F.9 R and the value of that property is £100,000, then £80,000 of that exposure may be treated as fully and completely secured and risk weighted at 35%. The remaining £20,000 should be risk weighted at 75%. A diagrammatic illustration of this example is in MIPRU 4.2F.31G (2).
- (2)
A diagrammatic illustration of the example in MIPRU 4.2F.31G (1).
Unsecured component risk weighted at 75%
Example
Secured component risk weighted at 35%
£100,000 loan secured on residential property valued at £100,000
First £80,000 (i.e. 80% LTV) risk weighted at 35%
Remaining £20,000 (i.e. above 80% LTV) risk weighted at 75%
Overall risk weight is 43%
- (3)
The same approach applies to exposures described in MIPRU 4.2F.9 R. On inception, a risk weight of 35% should be applied to the first 80% of the principal/"purchase price" outstanding, with a risk weight of 75% being applied to the remainder of the principal exposure.
- (1)
The application of MIPRU 4.2F.33 R may be illustrated by an example. Where a first-charge mortgage exposure of £50,000 from another lender is secured on residential property in the United Kingdom that satisfies the criteria in MIPRU 4.2F.4 R to MIPRU 4.2F.29 R and the value of that property is £100,000, then a firm with a second-charge mortgage of £60,000 on the same property may treat £30,000 of that exposure as fully and completely secured and risk weight it at 35%, treat a further £20,000 as unsecured and risk weight it at 75%, and risk weight the remaining £10,000 at 100%. A diagrammatic illustration of this example is in (2).

• Remaining second-charge mortgage, i.e. £10,000
£100,000
£20,000 of second-charge - risk weighted at 75%
• Second-charge mortgage up to maximum of 100% of property value, i.e. £20,000
£30,000 of second-charge - risk weighted at 35%
• Second-charge mortgage up to maximum of 80% of property value, i.e. £30,000
First-charge mortgage (£50,000)
• Other lender has first-charge over property with outstanding loan balance of £50,000

The application of value adjustments to either the secured or the unsecured component of an exposure secured on residential property may be illustrated on the basis of a £110,000 loan on a property valued at £100,000, where £80,000 of the loan is secured, £30,000 of the exposure is unsecured and a value adjustment of £20,000 is taken.
- (1)
Value adjustment applied to unsecured component:
- (a)
Value adjustment of £20,000 taken on £30,000 unsecured exposure.
- (b)
Value adjustment exceeds 20%, so the firm should risk weight the remaining £10,000 unsecured exposure at 100% (as per MIPRU 4.2F.55 R).
- (c)
The risk weight to be applied to the secured exposure of £80,000 is 100% (as per MIPRU 4.2F.51 R).
- (a)
- (2)
Value adjustment applied to secured component:
- (a)
Value adjustment of £20,000 taken on £80,000 secured exposure.
- (b)
Value adjustment exceeds 20%, so the firm should risk weight the remaining £60,000 secured exposure at 50% (as per MIPRU 4.2F.51 R).
- (c)
The risk weight to be applied to the unsecured exposure of £30,000 is 150% (as per MIPRU 4.2F.55 R).
