>>good afternoon aon hewitt.item 8 on our agenda i am going to discuss what we are previously done. we are trying to maintain sustainability under the city plan ppo and the early retirees to refresh the memory of the board and the public who may be interested. this population is pulled together so all of the loss experience and the subsequent rating action on the former rate period and how this is done collectively. but we have done is we've decided that we want this program and this program has been noted as the city plan. this is been the plan of the city and has been reviewed in several meetings prior to this. what we decided in may 2015 is to take some of the available stabilization dollars and reduce thhe contributions to the city plan for active and in early retirees. this had been to the lane and this would be very expensive because of renewing the rate. one of the board members, commissioner lim, asked me to help with this and i honored his request and we did the calculations so that was the driving force
