For the two-user Gaussian interference channel we show that, up to second order in the signal-to-noise ratio (SNR), the mutual information between each transmitter and intended receiver depends only on the covariance matrices of the input distributions. Our analysis suggests that in the low SNR regime there is an interference threshold above which it is better for the users to alternate signal transmission than to transmit simultaneously.
