  (a) It is in the public interest and it is the policy of the state to foster and promote borrowing of money by governmental units within the state for financing public improvements, for financing community water supplies and noncommunity water supplies, and for financing other municipal purposes from proceeds of bonds or notes issued by those governmental units; to assist those governmental units in fulfilling their needs for those purposes by creation of indebtedness; to provide for the orderly marketing of municipal obligations; and to the extent possible, to encourage continued investor interest in the bonds or notes of those governmental units as sound and preferred securities for investment.

  (b) It is in the public interest and it is the policy of this state to encourage governmental units within this state to continue their independent undertakings of public improvements, community water supplies and noncommunity water supplies, and new municipal purposes and the financing for them, and to assist the governmental units by making money available for orderly financing of public improvements, community water supplies and noncommunity water supplies, and other municipal and governmental purposes.

  (c) Credit and municipal bond market conditions require the exercise of the powers of this state in the interest of its governmental units to further and implement such policies by authorizing the Michigan municipal bond authority to have full powers to borrow money and to issue its bonds and notes to make money available through the Michigan municipal bond authority at reduced rates or on more favorable terms for borrowing by the state’s governmental units through the purchase of the obligations of the governmental units in fully marketable form and by granting broad powers to the Michigan municipal bond authority to accomplish and to carry out these policies of this state that are in the public interest of this state and of its taxpayers and residents.
