Restrictions on Cash and Cash Equivalents

The nature of the Company's business requires that it maintain amounts due from correspondent banks which, at times, may exceed federally insured limits. The balances in these accounts at December 31, were as follows:

	2017		2016
	(Dollars in thousands)
Noninterest bearing accounts	$	210	$	289
Federal Reserve Bank of Boston	34,344		34,777
FHLB of Boston	310		572

No losses have been experienced in these accounts and the Company believes it is not exposed to any significant risk with respect to the accounts.

The Company had no requirement to maintain contracted clearing balances at December 31, 2017 or 2016. Balances at the Federal Reserve Bank of Boston and a portion of the funds at the FHLB are classified as overnight deposits as they earn interest. The Company is required to maintain vault cash or noninterest bearing reserve balances with Federal Reserve Bank of Boston. Total reserve balances required at December 31, 2017 and 2016 were $1.4 million and $891 thousand, respectively, which were both satisfied by vault cash.
