(e) A transfer of property from A to B in trust for the beneficial use of C without reservation, except to the extent that if C should predecease A the property will revert to the latter, constitutes a gift from A to C. The tax in such case is computed as though the transfer were made subject to a contingency or condition (see Section 15210).

It is assumed in this regulation that the transfers were not made for an adequate and full consideration in money or money's worth.
