Restricted On Cash And Due From Banks And Certain Securities	Note 4 - Restrictions on cash and due from banks and certain securities The Corporation’s banking subsidiaries, BPPR and PB, are required by federal and state regulatory agencies to maintain average reserve balances with the Federal Reserve Bank of New York (the “Fed”) or other banks. Those required average reserve balances amounted to $1.5 billion at June 30, 2018 (December 31, 2017 - $1.4 billion). Cash and due from banks, as well as other highly liquid securities, are used to cover the required average reserve balances. At June 30, 2018, the Corporation held $43 million in restricted assets in the form of funds deposited in money market accounts, debt securities available for sale and equity securities (December 31, 2017 - $41 million). The amounts held in debt securities available for sale and equity securities consist primarily of restricted assets held for the Corporation’s non-qualified retirement plans and fund deposits guaranteeing possible liens or encumbrances over the title of insured properties.
