  The current status of the search for indirect CP violation in the neutral D
meson system at the B-factories and at LHCb is reported. The indirect CP
asymmetry search is performed by the measurement of the proper-time asymmetry
($A_{\Gamma}$) in decays of $D^0-\bar{D^0}$ mesons to CP eigenstates, $K^-K^+$
and $\pi^- \pi^+$, and by $y_{CP}$, the ratio between the effective lifetime
measured in decay to a CP eigenstate and that to the mixed eigenstate $K \pi$.
All results are consistent with the no CP violation hypothesis. The latest
world averages for mixing and CP asymmetry in the charm sector evaluated by the
Heavy Flavour Averaging Group are presented. The no mixing hypothesis is
excluded at more than 12 standard deviations. The search for direct and
indirect CP violation in the charm sector is consistent with no CP violation at
2.0% confident level.
