 and sometimes reimbursement income or profits sharing arrangements.
a/ License fees or upfront payments
If the license to our intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, we recognize revenues from non-refundable upfront fees allocated to the license at the point in time the license is transferred to the customer and the customer has the right to use the license.
For licenses that are bundled with other promises, we utilize judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time. If the performance obligation is satisfied over time, revenue is then recognized based on a pattern that best reflects the transfer of control of the service to the customer. 
b/ Milestone Payments other than sales based milestones
A milestone payment is only included in the transaction price to the extent that it is highly probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Where milestone payments are included in the transaction price we estimate the amount to be included in the transaction price using the most likely amount method. The transaction price is allocated to each performance obligation on a stand-alone selling price basis. We recognize revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, we re-evaluate the probability of achievement of such milestones and any related constraint. If necessary we adjust our estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect revenue and earnings in the period of adjustment.
c/ Reimbursement Income for R&D Services
Collaboration and license agreements may include reimbursement or cost sharing for research and development services: such as outsourcing costs and payment for FTEs at contractual rates. R&D services are performed and satisfied over time given that the customer simultaneously receives and consumes the benefits provided by us.
Such costs reimbursements received are recognized in revenues when costs are incurred and agreed by the parties when we are acting as a principal in the scope of our stake of the R&D activities. If the later condition is not fulfilled, costs reimbursements are accounted for as a decrease of the related expenses.d/ Sales based milestone payment and Royalties 
License and collaboration agreements include sales-based royalties, including commercial milestone payments based on the level of sales, and the license has been deemed to be the predominant item to which the royalties relate. Related revenue is recognized as the subsequent underlying sales occur.
(iv) allocate the transaction price to the
