If any person or entity licensed, registered, or incorporated or otherwise formed pursuant to this chapter shall not pay, after due notice, any such assessment or any penalty or forfeiture incurred under any section of this chapter, the superintendent may, in his or her discretion, apply in payment thereof, with interest at the legal rate, so much as may be necessary of the interest accruing on any stocks or bonds deposited with him or her by such person or entity licensed, registered, or incorporated or otherwise formed pursuant to this chapter pursuant to any requirement of this chapter.3.

The attorney general shall thereupon, in the name of the superintendent, or of the people of the state, institute such action or proceedings as the facts may warrant.4. The provisions of this section shall be applicable to any bank holding company, as that term is defined in article three-A of this chapter.
