The contract portfolio value is typically recorded as the annual value from the customer contract. However, in some cases – especially "as-used" (based on volume) and mixed contracts – estimates are required in order to derive the contract portfolio value. The key points in respect of valuation are:
- "As-used" contracts: These are more typical in workwear, hygiene and catering, where elements of the contract are often variable and based on usage. Valuation is based on historic data (where available) or forecast values.
- Income annualisation: In some instances, where for example the underlying contract systems cannot value portfolio or there is a significant "as-used" element, the portfolio valuation is calculated using an invoice annualisation method.
- Inter-company: The contract portfolio figures include an element of inter-company revenue.
- Job work and extras: Many of the contracts within the contract portfolio include ad hoc and/or repeat job work and extras. These values are excluded from the contract portfolio.
- Rebates: The contract portfolio value is gross of customer rebates. These are considered as a normal part of trading and are therefore not removed from the portfolio valuation.
