At any time when no bonds or obligations theretofore assumed by the authority are outstanding, the board may adopt a resolution, which shall be duly entered upon its minutes, declaring that the authority shall be dissolved. Upon the filing for record of a certified copy of the resolution in the office of the judge of probate of the county, the authority shall thereupon stand dissolved and, in the event it owned any property at the time of its dissolution, the title to all its properties shall thereupon pass to and be divided and apportioned among Lamar County and any other county or counties in which any part of the service area may be located, all in such manner and to such extent as may be provided in the authority’s certificate of incorporation, as amended. In the absence of a contrary provision in the certificate of incorporation, as amended, title to real estate and tangible personal property, other than cash, shall vest in the county in which the real estate or tangible personal property is located and the title to cash on hand and in banks, accounts receivable, choses in action, and other intangible property, other than intangible interest in land, shall vest in all of the counties in which any part of the service area lies. Each such county shall have title to the cash and intangible items as a tenant in common thereof, the fractional interest of each such tenant in common in the items being represented by a fraction the numerator of which is an amount equal to the gross revenues derived by the authority during its then next preceding complete fiscal year from service rendered in that part of its service area within that county and the denominator of which is an amount equal to the gross revenues derived by the authority during the same period from services rendered or otherwise in its entire service area.
