Standard & Poor’s Financial Services LLC has determined that the city of West Des Moines will maintain its top AAA/Stable credit rating. West Des Moines is the only city in Iowa with the AAA rating from S&P, according to a release from the city. The top rating allows the city to compete in the marketplace and garner lower interest rates for the repayment of debt. The S&P report said the top rating reflects the ratings agency’s view that West Des Moines has a very strong economy, strong city management and financial policies, and strong budgetary performance and flexibility, according to the release. West Des Moines plans to issue an estimated $30 million in general obligation bonds this week for public improvements and construction pursuant to the Urban Renewal Plan for the Alluvion Urban Renewal District, the area in the southeast part of the city that was created as a result of Microsoft Corp.’s decision to locate a $1 billion data center. The city said in the release that it will save approximately $135,000 in interest by taking out an additional $3 million in General Obligation Urban Renewal Refunding Bonds to refinance bonds issued in 2008. The city establishes a credit rating from both Moody’s and Standard & Poor’s rating services, rotating between the two services for credit ratings each year. The city maintained its top Aaa credit rating from Moody’s Investors Service in July 2014.
