STI 2018 Annual Report

Notes to Consolidated Financial Statements, continued 140 Public Deposits The Company holds public deposits from various states in which it does business. Individual state laws require banks to collateralize public deposits, typically as a percentage of their public deposit balance in excess of FDIC insurance and may also require a cross-guarantee among all banks holding public deposits of the individual state. The amount of collateral required varies by state and may also vary by bank within each state, depending on the individual state’s risk assessment of each participating bank. Certain states in which the Company holds public deposits use a pooled collateral method, whereby in the event of default of a bank holding public deposits, the collateral of the defaulting bank is liquidated to the extent necessary to recover the loss of public deposits of the defaulting bank. To the extent the collateral is insufficient, the remaining public deposit balances of the defaulting bank are recovered through an assessment of the other banks holding public deposits in that state. The maximum potential amount of future payments the Company could be required to make is dependent on a variety of factors, including the amount of public funds held by banks in the states in which the Company also holds public deposits and the amount of collateral coverage associated with any defaulting bank. Individual states appear to be monitoring this risk and evaluating collateral requirements; therefore, the likelihood that the Company would have to perform under this guarantee is dependent on whether any banks holding public funds default as well as the adequacy of collateral coverage. Other In the normal course of business, the Company enters into indemnification agreements and provides standard representations and warranties in connection with numerous transactions. These transactions include those arising from securitization activities, underwriting agreements, merger and acquisition agreements, swap clearing agreements, loan sales, contractual commitments, payment processing, sponsorship agreements, and various other business transactions or arrangements. The extent of the Company’s obligations under these indemnification agreements depends upon the occurrence of future events; therefore, the Company's potential future liability under these arrangements is not determinable. STIS and STRH, broker-dealer affiliates of the Company, use a common third party clearing broker to clear and execute their customers’ securities transactions and to hold customer accounts. Under their respective agreements, STIS and STRH agree to indemnify the clearing broker for losses that result froma customer’s failure to fulfill its contractual obligations. As the clearing broker’s rights to charge STIS and STRH have no maximum amount, the Company believes that themaximumpotential obligation cannot be estimated. However, to mitigate exposure, the affiliate may seek recourse from the customer through cash or securities held in the defaulting customer's account. For the years ended December 31, 2018, 2017, and 2016, STIS and STRH experienced minimal net losses as a result of the indemnity. The clearing agreements expire in May 2020 for both STIS and STRH.
