  We present preliminary results for strange and charm contributions to nucleon
charges and moments. The scalar, axial and tensor charges, and unpolarized
first moments are calculated using clover-on-HISQ formulation and cover four
lattice spacings, $a=\{0.06,0.09,0.12, 0.15\}$~fm, and three pion masses,
$M_\pi=\{310,220,130\}$~MeV. The renormalization factors are calculated
nonperturbatively using the RI-sMOM scheme. We carry out a chiral and continuum
extrapolation to obtain physical results.
