Invoice Payment Practices

This information is as reported by the business, and responses are in their own words.

Payment Terms

Standard payment terms

Qualifying contracts for this entity contain a number of different payment periods: • Immediate • 30 days • 60 days • 45 days • 30 days and 5th of the following month • 60 days and 5th of the following month Payments are made from date of receipt of invoice.

Were there any changes to the standard payment terms in the reporting period?

Standard 30-day terms for SMEs were introduced in place of a previous offer of 30 day terms upon application by the vendor.

Any other information about payment terms

1) Statistics Reported: Intercompany invoices and performance have been excluded from reported statistics as these are generally wholly owned group companies and would distort performance if included. 2) Payment terms for SMEs and 'Paid on Time' monitoring: Preferential payment terms of 30 days are put in place for vendors that are confirmed as SMEs (Small and Medium Enterprises). We closely monitor our KPIs on a weekly basis to ensure that vendors (including SMEs) are paid on time. Corrective actions are taken to remedy any late payment issues where these are within the entity’s control.

Maximum contractual payment period agreed

60

Dispute Resolution Process

We offer our suppliers the following support and service: • Enquiries and complaints can be logged through our Helpdesk support system (mail or telephone). Issues are often related to incorrect invoice submission, payment terms are not as per contract, PO details are wrong / nonexistent etc. Key performance metrics are monitored for quality of Helpdesk support. • Our Supplier web pages also include details and a link to our Speak Up channels that enable concerns to be raised, including channels managed independently of GSK and the option to do so anonymously, although naturally it helps in resolving matters if we know as much as possible about the issue and complainant. • We have invested in Customer Relationship Management (CRM) to ensure effective and independent supplier follow up and support to our suppliers raising issues.
