Our deposit portfolio includes deposits offered through the Promontory Interfinancial Network that are comprised of Certificate of Deposit Account Registry Service^® ("CDARS") balances included in time deposits and Insured Cash Sweep^® ("ICS") balances included in money market deposits. In addition, in 2016, we began offering deposits through Reich & Tang Deposit Networks, LLC, comprised of Demand Deposit Marketplace^SM("DDM") balances, mostly in money market deposits. Through these two networks we are able to offer our customers access to FDIC-insured deposit products in aggregate amounts exceeding current insurance limits. When we place funds through CDARS,ICS and DDM, on behalf of a customer, we have the option of receiving matching deposits through the network's reciprocal deposit program. We consider the reciprocal deposits to be in-market deposits as distinguished from traditional out-of-market brokered deposits. We had $13.5 million and $15.1 million in CDARS and $41.0 million and $29.0 million in ICS balances in the reciprocal deposit program at December 31, 2017 and 2016, respectively. In addition, we had $29.2 million and $36.4 million in DDM balances in the reciprocal deposit program at December 31, 2017 and 2016, respectively. We also have the ability to place deposits through the networks for which we receive no matching deposits ("one-way" deposits). One-way CDARS and ICS deposits totaled $4.2 million and $361 thousand at December 31, 2017 and 2016, respectively.

The aggregate amount of deposit overdrafts that have been reclassified as loan balances was $224 thousand and $229 thousand at December 31, 2017 and 2016, respectively. Collectability of these overdrafts is subject to the same credit review process as other loans.

The Bank accepts deposits from shareholders, directors and employees in the normal course of business, and the terms are comparable to those with non-affiliated parties. The total deposits from directors and their businesses, and executive officers were $29.9 million and $7.3 million at December 31, 2017 and 2016, respectively.
