Miss. Code Ann. § 31-17-47: Miss. Code Ann. § 31-17-47

In the event a surplus is remaining in the treasury of any county, municipality or other taxing district at the end of any fiscal year as provided by Section 31-17-45 , then within ten (10) days thereafter the said board of supervisors, mayor and board of aldermen, or the governing body of other taxing districts may advertise its intention to purchase the bonds of such county, municipality, or other taxing district by publishing a notice thereof at least ten (10) days in some newspaper published in said county and one (1) other financial journal having a general circulation among bond buyers and dealers. Said advertisement shall state the amount of bonds to be purchased, the maximum price to be paid therefor, and the date upon which it will receive sealed proposals for outstanding bonds of said taxing district.

Said board of supervisors, mayor and board of aldermen, or the governing body of other taxing districts shall accept the bid or proposal determined and adjudged by it to be most favorable to such taxing district. The interest rate and maturity of the bonds to be purchased shall be taken into consideration in determining the best bid.

However, it shall be optional with the board of supervisors, mayor and board of aldermen, or the governing body of other taxing districts as to whether or not it will advertise its intention to purchase its bonds as provided by this section. In the event the board of supervisors, mayor and board of aldermen, or the governing body of other taxing districts shall determine that it is most advantageous to the county, city, or other taxing district not to so advertise, it may buy and retire its bonds at a private sale without publication of its intention to do so.
