Append and Spatial Reference

I understand that the Append tool will project the features in the input feature class to the coordinate system used by the target feature class if their spatial references do not match.

But, how does the Append tool know what geographic transformation to use? If, for example, my input data were WGS 1984 and my target data were NAD 1983, what geographic transformation would be used by the Append? Would it default to a particular transformation such as NAD_1983_To_WGS_1984_1?
