Finally, due to the technological uncertainties that are a feature of the Galileo and EGNOS programmes, contract prices cannot always be forecast accurately and it is therefore desirable to conclude contracts in a specific form that do not stipulate a firm fixed price and include clauses to safeguard the financial interests of the Union.
Ar deireadh, mar gheall ar na héiginnteachtaí teicneolaíocha a bhaineann le clár Galileo agus le clár EGNOS, ní féidir i gcónaí praghsanna conarthaí a thuar go beacht agus is inmhianaithe dá bhrí sin conarthaí a thabhairt i gcrích i bhfoirm shonrach, foirm nach sonraíonn praghas seasta daingean agus a áiríonn clásail chun leasanna airgeadais an Aontais a chosaint.
