Colorado Revised Statutes Title 11. Financial Institutions § 11-54-105. Limitations upon issuance

No public securities may be refunded under this article unless the holders thereof voluntarily surrender them for exchange or payment, or unless they either mature or are callable for prior redemption under their terms within ten years from the date of issuance of the refunding public securities. Provision shall be made for paying the public securities within said period of time. No maturity of any public security refunded may be extended over fifteen years, nor may the net effective interest rate of the issue of refunding securities be increased to any rate exceeding the maximum net effective interest rate authorized by the governing body. The principal amount of the refunding public securities may exceed the principal amount of the refunded public securities if the aggregate principal and interest costs of the refunding public securities do not exceed such unaccrued costs of the public securities refunded, except to the extent any interest on the public securities refunded in arrears or about to become due is capitalized with the proceeds of refunding public securities. The principal amount of the refunding public securities may also be less than or the same as the principal amount of the public securities being refunded so long as provision is duly and sufficiently made for their payment. The limitations of this section shall not apply to the refunding of public securities in order to avoid default.
