(a) Each agent of depository shall report in writing to the administrator within two business days after any withdrawal, substitution, or addition of pooled securities and shall state the name and market value of the securities withdrawn, substituted, or added together with the total deposits then secured by the pool. This information shall be available from the administrator to the treasurer upon request.

(b) Each depository shall report in writing to the administrator weekly, giving the total amount of all deposits held by the depository pursuant to this article. The report shall be as of close of business on Wednesday of each week and shall be delivered to the office of the administrator, deposited in the United States mail, postage prepaid, or delivered electronically via email, or other electronic means approved by the administrator, addressed to the office of the administrator, within five business days.
