I' ~ Attachments as stated Blake Myton Investment Manager October 29, 2004 Mr. Ronald W. McLemore City Manager 1126 East State Road 434 Winter Springs, FL 32708 Re: Recommended changes to the Investment Policy Statement for the Winter Springs General Employee Retirement System Dear Mr. McLemore: I am writing you regarding the recommended changes to the Winter Springs General Employee Retirement System's current investment policy we discussed at this week's pension meeting. It is our belief that these recommended changes will allow for greater flexibility in the investment of plan assets and as a result will allow Trusco Capital management as the plan's inves~ent manager, to more effectively manage the assets of the plan. In today's increasing volatile market, it is our belief that requiring relatively high minimum requirements to specific asset class, ie minimum 15% in Small Cap equities, can lower the chances for the plan to achieve the actuarial assumed rate of return. Our recommendations will focus on the specific asset classes outlined in the IPS and not result in any changes to the plan's overall target allocation of70% in a diversified portfolio of equity securities and 30% in more stable fixed income instruments. We would strongly suggest the trustees consider the following amendments to the IPS: 1. Section VIT, #1 Stock Category . Target Range Large Cap Growth 10% - 30% Large C~p Value 10% - 30% Small Caps 5% - 20% Mid Caps 5% - 20% International 5% - 20% Fixed Income 15% - 35% Cash Equivalents 0% - 10% The intention of these changes is allow for less exposure to the more volatile equity assets classes of small caps, mid caps and international ~quities. I:n addition it will allow for less exposure to the'fixed income asset class when the manager deems appropriate. This will not effect the plan's target allocation of 70% stock and 30% bond target or the allowable +/- 5% variance already in the IPS. If you have any questions or comments, please do not hesitate to contact me by phone at (407)-237- 5816 or by email atblake.mvton@truscocaDital.com.

PFM Asset Management LLC PFM Advisors November 8, 2004 (. r-eJ.ll sui) Ms. Michelle Greco, CPA Finance Director City of Winter Springs 1126 East S.R. 434 Winter Springs, Florida 32708 Dear Ms. Greco: On behalf of PFM Asset Management,. thank you for the opportunity to review the proposed Investment Policy Statement changes for the City of Winter Springs General Employees Pension System. We have carefully evaluated the proposal from Blake Myton of Trusco Capital Managenient from his letter dated October 29, 2004. Mr. Myton's proposed changes are below; our opinion follows. Current Policy Recommended Changes High Grade Equity 10% - 30% High Grade Equity Income 15% - 25% Small Caps 15% - 30% Mid Caps 15%-30% International 5% - 15% Large Cap Growth Large Cap Value Small Caps Mid Caps International Fixed Income Cash Equivalents 10% - 30% 10% - 30% 5% - 20% 5% - 20% 5% - 20% 15% - 35% 0% - 10% The overall requirement isfor 70% of the Plan's assets to be allocated to equity investments (stock) and for other 30% to be allocated to fixed income securities (bonds) with no more than a 5% deviation. The variance of between 65% to 75%for equity investments an(125% to 35%for fIXed income securities will remain unchanged. PFM's position: Overall, we believe these to be positive changes for the Systems' Investment Policy and have potential to realize the benefits that Trusco identified -lessening of the requirement to have assets invested in the generally more volatile mid-cap, small-cap and international equity asset sub-classes and the flexibility to change the fixed income allocation from a fixed 30%. The current policy percentages were developed in conjunction with Trusco and we think it appropriate to seek its counsel in any changes. Ms. Michelle Greco November 8, 2004 Page 2 We would however recommend that the System consider some modification to the proposal. 1) A range of fixed income asse~ from 15% to 35% is very broad. and puts a great deal of discretion in the hands of the manager. We recommend that the Fixed Income range specified in Tmsco's chart (reproduced above) be reduced to 25% - 35%; in other words, a 5% range on each side of the neutral position of 30%. In addition, it should be stated in the revised policy that the Cash Equivalents allocation is part of the Fixed Income category. 2) The large cap growth and value ranges are very broad which can permit a very strong tilt in favor of one strategy over the other. We recommend that there be another constraint placed in the policy that the ratio of large cap value to large cap growth, or large cap growth to large cap value, should not exceed 2:1. lbis :ratio does not apply to the other asset classes. 3) A statement of the rebalancing policy should be added. We recommend that the plan's asset allocation be reviewed no less frequendy that quarterly. If the percentage of assets invested in any of the asset classes described above falls outside the applicable range, we recommend that they be rebalanced such that the percentage of assets once again falls within the range specified by the policy. . 4) The System should have the opportunity to review any changes in proposed investtnent options. If any new options have higher fees than those originally proposed, Trusco should not pass these higher fees along to the System. Any lower fee options employed should result in a fee reduction. Please do not hesitate to contact me or John Molloy if you have any questions or would like further clarification on any of the points we raised above. Thank you again for the opportunity to be of service to the City of Winter Springs ~d the City's Retirement System.
