  5. 2013 - 2016 Forecast - Disclaimer • The 2013-2016 forecast herein provides an indicative RNS rate trend; it should be used for illustrative purposes only. • The estimated data utilized by the PTO AC to develop this forecast of RNS rates is based upon estimated capital additions provided to the Committee by all the New England Transmission Owners. Estimates for 2013 capital additions will be finalized during the normal course of update to the RNS rate effective June 1, 2013 and will reflect more current information. • The PTO AC acknowledges that this 2013-2016 forecast is based on a number of assumptions and variables including, among others, estimated project need, design, scope, labor & materials costs, inflation, site & permitting approvals, transmission in-service dates, estimated carrying charges & coincident peak network loads. It is therefore expected that such estimates and assumptions will change over time as more current data become available. • In addition, the 2013-2016 forecast reflects gross costs and does not include assumptions pertaining to savings (e.g., associated with congestion, unlocked capacity, etc.) or prior year true-up adjustments.
