  We discuss two different definitions of partonic orbital angular momentum
given in the literature in terms of the Fourier transform of a Wigner
distribution, $F_{14}$, and a twist three generalized parton distribution,
$\tilde{E}_{2T}$, respectively. We derive a relation between the two
definitions which reflects their specific spin and intrinsic transverse
momentum/transverse space correlations as well as their gauge link structure.
