AIM Investments announced today that it has made several important enhancements to The AIM College Savings Plan. The changes, which take effect today, include new allocation investment options and lower expenses. The plan�s new investment options � including five allocation portfolios with allocations that range from conservative to growth, and five enrollment-based portfolios that range from 13+ Years to College to College Now � invest in the AIM Allocation Solutions funds. �These investment enhancements are based on the timeless principle of asset allocation � a strategy that seeks to balance risk and reward by spreading investments across several types of asset classes such as stocks and bonds,� said Gary Wendler, AIM�s director of Product Strategy and Investment Services. �We researched AIM�s broad range of mutual funds to determine which funds best represented each asset class within the five portfolios. These portfolios each invest in nine to 11 underlying funds, all actively managed by teams of experienced portfolio managers.� AIM also has modified the annual account fee structure to include new options for fee waivers. There is no annual account fee when contributions are made through an automatic investment plan or an account balance of at least $25,000.
