The financial institution shall be: (i) a national bank, federal savings bank, federal savings and loan association or federal credit union; provided, however, that the bank, association or credit union may transact business and has its main office or a branch office in the commonwealth; or (ii) a trust company, credit union, co-operative bank or savings bank; provided, however, that the company, credit union or bank is organized and exists under the laws of the commonwealth or any other state or otherwise may transact business in the commonwealth and has its main office or a branch office in the commonwealth. A candidate and the treasurer of a political committee shall file with the director, on or before the third business day following the designation of the depository, a certificate of appointment containing the name of the financial institution so designated and the name of the candidate or political committee and shall authorize the financial institution to submit the reports required by subsection (d). The certificate of appointment reflecting the financial institution's agreement to comply with this section shall also be signed by an authorized employee of the financial institution.

(b) A candidate and the treasurer of a political committee required to designate a depository shall deposit contributions in the form received within 7 days of receipt. Any candidate or treasurer required to designate a depository shall file with the director, by the fifth and twentieth days of each month, the following information: (i) a list of all contributions of more than $50 deposited as of the first and fifteenth days of the month and since the last statement, including an alphabetical list of names and addresses of each person making a contribution; (ii) for a person who has made a contribution in an amount of or with a value of $200 or more in any calendar year, the occupation and employer of the contributor and the information for each contribution of less than $200 if the aggregate of all contributions received from the contributor within any calendar year is $200 or more; and (iii) a summary of all contributions of $50 or less deposited that are not itemized on the report.

All checks drawn on the campaign account shall be payable either to the order of a named payee, not the candidate or treasurer, or, if the check is for not more than $100, may be payable to the candidate or treasurer. The memo line of the check shall be used by the political committee issuing the check to indicate the specific purpose of the expenditure. A political action committee or political party committee making an expenditure to support or oppose a candidate shall identify the candidate on the check.

A candidate or treasurer of a political committee required to designate a depository may make expenditures by wire transfer or other electronic means for broadcast, cablecast or other media services and for payroll services made in connection with employee deductions and withholdings.
