When a CCA terminates, the arm’s length principle requires that each participant retains an interest in the results, if any, of the CCA activity consistent with their proportionate share of contributions to the CCA throughout its term (adjusted by any balancing payments actually made, including those made as a result of the termination), or is appropriately compensated for any transfer of that interest to other participants ...

Buy-in and buy-out payments should be treated for tax purposes in the same manner as would apply under the general rules of the tax system(s) (including conventions for the avoidance of double taxation) applicable to the respective participants as if the payment were made outside a CCA as consideration for the acquisition or disposal of the interest in the results of the prior CCA activity ...

The guidance in Chapters I – III and Chapter VI is fully applicable to determining the arm’s length amount of any buy-in, buy-out or balancing payments required. There may be instances where no such payments are required under the arm’s length principle. For example, a CCA for the sharing of administrative services would generally only produce benefits to participants on a current basis, rather than any valuable on-going results ...

Similar issues could arise when a participant leaves a CCA. In particular, a participant that leaves a CCA may dispose of its interest in the results, if any, of past CCA activity (including work in progress) to the other participants. Any such transfer should be compensated according to the arm’s length principle. Such compensation is referred to in this chapter as a “buy-out payment” ...

The amount of a buy-in payment should be determined based upon the value (i.e. the arm’s length price) of the interest in the intangibles and/or tangible assets the new entrant obtains, taking into account the new entrant’s proportionate share of the overall expected benefits to be received under the CCA. There may also be cases where a new participant brings existing intangibles or tangible assets to the CCA, and that balancing payments may be appropriate from the other participants in recognition of this contribution. Any balancing payments to the new entrant could be netted against any buy-in payments required, although appropriate records must be kept of the full amounts of the separate payments for tax administration purposes ...

Changes in the membership of a CCA will generally trigger a reassessment of the proportionate shares of participants’ contributions and expected benefits. An entity that becomes a participant in an already active CCA might obtain an interest in any results of prior CCA activity, such as completed or work-in-progress intangibles or tangible assets. In such cases, the previous participants effectively transfer part of their respective interests in the results of the prior CCA activity to the new entrant. Under the arm’s length principle, any such transfer of intangibles or tangible assets must be compensated based on an arm’s length value for the transferred interest. Such compensation is referred to in this chapter as a “buy-in payment” ...
