At September 30, 2017 and December 31, 2016, our weighted average servicing fee was 48.0 basis points and 47.8 basis points, respectively. We held cash in escrow for these loans totaling $506.6 million and $401.7 million at September 30, 2017 and December 31, 2016, respectively, which is not reflected in our consolidated balance sheets. These escrows are maintained in separate accounts at two federally insured depository institutions, which may exceed FDIC insured limits.
