Free Writing Prospectus Filed Pursuant to Rule 433 Morgan Stanley ETF-MAP Index Registration Statement No. 333-178081 December 6, 2012 The Morgan Stanley ETF-MAP Index (the "Index") is a rules-based quantitative strategy (the "Index Methodology") which uses modern portfolio theory principles and the related concept of efficient frontier to attempt to maximize returns for a given level of risk. The Index components consist of U.S.-listed ETFs representing U.S. and non-U.S. equities, fixed income securities, commodities and cash (the "Index Components"). The level of the Index is determined by the weighted return of the optimized portfolio of Index Components (the "Asset Portfolio") reduced, because this is an excess return index, by the return on an equivalent cash investment receiving the Federal Funds rate. At each Monthly Rebalancing the Index Methodology determines the optimal weightings of each component in the Asset Portfolio by analyzing historical returns and volatility for each Index Component and the historical correlation between each pair of components. In particular, the Index Methodology seeks to determine the Asset Portfolio that had the maximum historical return with 5% annualized volatility over the prior 60-business day period. The exposure of the Index to each market sector and the weighting of each Index Component are subject to limits outlined below. In addition, there is a Daily Allocation, based on a 5% volatility target (the "Volatility Target"), between the Asset Portfolio and cash. Accordingly, the exposure to the Asset Portfolio will be monitored and adjusted so that it generally equals the Volatility Target divided by the realized volatility of the Asset Portfolio. A servicing cost of 0.50% per annum, calculated on a daily basis, and rebalancing costs of 0.38% per rebalance are deducted when calculating the Index performance. The rebalancing costs will apply to all Monthly Rebalancings and Daily Allocations, but only to the non-cash portion of the Asset Portfolio actually rebalanced. ETF-MAP stands for "Exchange Traded Fund -- Multi-Asset Portfolio" HISTORICAL ASSET ALLOCATION: PREVIOUS 12 MONTHS [GRAPHIC OMITTED] CHANGE IN INDEX LEVEL (SIMULATED AND ACTUAL RETURNS) [GRAPHIC OMITTED] * Returns from January 2, 2003 to March 11, 2012 are simulated.

All returns except year-to-date 2012 returns are annualized. 2 Year-to-date 2012 returns are not annualized (as of Nov 30, 2012). NOTE ON SIMULATED RETURNS: Back-testing and other statistical analyses provided herein use simulated analysis and hypothetical circumstances to estimate how the Index may have performed between January 2, 2003 and March 11, 2012, prior to its actual existence. The results of such back-testing should not be considered indicative of actual results of an investment in the Index. Morgan Stanley provides no assurance or guarantee that securities linked to the Index will operate or would have operated in a manner consistent with these materials. The hypothetical historical levels presented herein have not been verified by an independent third party, and such hypothetical historical levels have inherent limitations. Alternative simulations, models or assumptions might produce significantly different results and prove to be more appropriate. Actual results will vary, perhaps materially, from the simulated returns presented in this free writing prospectus. Because certain ETFs included in the Index Components existed for only a portion of the back-tested period, substitute data has been used for portions of the simulation. Wherever data for one or more ETFs did not exist, the simulation has included the value of each ETF's benchmark index less the relevant current expense ratio. The purpose of this data substitution is to replicate as nearly as possible the returns that would have been expected had the ETF existed and tracked its relevant benchmark index.
