As of September 30, 2017, the outstanding balance under our financing arrangements was funded at an advance rate of 87.8% that implies an average haircut of 12.2%. As of September 30, 2017, the weighted average “haircut” related to our repurchase agreement financing for our Agency RMBS (excluding Agency IOs), Non-Agency RMBS, CMBS and Agency IOs was approximately 4%, 25%, 20% and 25%, respectively. In the event we are unable to obtain sufficient short-term financing through existing financings arrangements, or our lenders start to require additional collateral, we may have to liquidate our investment securities at a disadvantageous time, which could result in losses. Any losses resulting from the disposition of our investment securities in this manner could have a material adverse effect on our operating results and net profitability. At September 30, 2017 and December 31, 2016, the Company had financing arrangements with eight counterparties. As of September 30, 2017, we had no counterparties where the amount at risk was in excess of 5% of the Company's stockholders’ equity. At December 31, 2016, the Company's only exposure where the amount at risk was in excess of 5% of the Company's stockholders' equity was to Deutsche Bank AG, London Branch at 5.1%. The amount at risk is defined as the fair value of securities pledged as collateral to the financing arrangement in excess of the financing arrangement liability. As of September 30, 2017, our available liquid assets included unrestricted cash and cash equivalents, overnight deposits and unencumbered securities that we believe may be posted as margin. The Company had $101.9 million in cash and cash equivalents, $8.9 million in overnight deposits in our Agency IO portfolio included in restricted cash and $243.1 million in unencumbered investment securities to meet additional haircuts or market valuation requirements. The unencumbered securities that we believe may be posted as margin as of September 30, 2017 included $35.1 million of Agency RMBS, $139.9 million of CMBS and $68.1 million of Non-Agency RMBS and other investment securities. The cash and unencumbered securities, which collectively represent 58.2% of our financing arrangements, are liquid and could be monetized to pay down or collateralize a liability immediately.
