The consideration payable for Tri-Solfen® is expected to be payable over a number of years, and relates to development milestones and sales performance. During the year, the development milestones have been remeasured and are now expected to happen later than initially anticipated. The sales performance royalties have been remeasured during the year reflecting an increase in management's best estimate of forecasted sales performance.

The consideration payable for Mirataz relates to sales performance and is expected to be payable over a number of years.

The consideration payable for StrixNB® and DispersinB® is expected to be payable over a number of years, and relates to sales performance. During the year the contingent consideration has been remeasured based on management's best estimate of forecasted sales performance. An Addendum to the contract was agreed during the year for a development milestone and sales performance in the Brazilian market.

The consideration for two separate licensing agreements for injectable solutions both relate to development milestones. Phycox relates to sales performance and arose as part of the acquisition of the trade and assets of PSPC Inc. in 2014.

Where a liability is expected to be payable over a number of years the total estimated liability is discounted to its present value. With the exception of Phycox, all contingent consideration liabilities relate to licensing agreements.
