What are IFRS reserves concerned with?

I am currently reading over a job description which, under duties, says that I would be required to assist in the calculation of IFRS reserves. Could anyone help me to understand what exactly this means?

I understand the concept of policy reserves - the amount of capital that the insurer is required to hold in order to be able to cover the value of the policy if they are required to pay out under it - but what is an IFRS reserve?
