IEM Prospectus: PRES12_WTA
2012 US Presidential Election Winner-Takes-All Market

On Friday, July 1, 2011, at 11:30am CDT, the Iowa Electronic Market (IEM) will open trading in a winner-takes-all market based on the 2012 U.S. Presidential election.

The payoffs in this market will be based on the popular vote received by the official Democratic and Republican nominees in the 2012 U.S. Presidential election. Payoffs are NOT affected by votes received by nominees from other parties, the outcome of the electoral college or any vote taken by the House of Representatives should such a vote be necessary.

This document describes the market and should be viewed as a supplement to the Trader's Manual. Except as specified in this prospectus, trading rules for this market are the same as those specified in the Trader's Manual for the Iowa Electronic Market.


Contracts

The financial contracts initially traded in this market are:

Code Contract Description
DEM12_WTA     $1 if the Democratic Party nominee receives the majority of popular votes cast for the two major parties in the 2012 U.S. Presidential election, $0 otherwise
 
REP12_WTA $1 if the Republican Party nominee receives the majority of popular votes cast for the two major parties in the 2012 U.S. Presidential election, $0 otherwise

Determination of Liquidation Values

This is a winner-takes-all market. The payoff will be determined by which of the two nominees receives the larger share of the popular vote cast for the Democratic and Republican candidates in the 2012 U.S. Presidential election.

Contracts associated with the nominee who does not receive the larger number of popular votes in the election will pay off $0. Contracts associated with the nominee that receives the larger number of popular votes will pay off $1, provided that there have been no contract spin-offs in the market. In the event of spin-offs, payoffs are determined as described below.

The election data posted on the New York Times official website at 5pm on Wednesday, November 7, 2012 will be the official source used to determine payoffs. In the event that the two parties' popular votes are not reported at that website by midnight, Wednesday, November 7, 2012, the Washington Post official website will become the official source. Should neither source report popular vote by midnight Wednesday, the information reported in the print version of the New York Times on Thursday, November 8, 2012, or as soon thereafter as reported, will be used. In the event that the election is delayed or postponed, liquidation will take place in a timely fashion after the close of polling sites for the popular vote.

Liquidation formulas can be viewed while you are logged into the IEM trading system by clicking on the market name, PRES12_WTA, at the upper right hand corner of the market window.

The judgment of the IEM Governors and Directors will be final in resolving questions of typographical or clerical errors and ambiguities.


Contract Spin-Offs

The Directors of the IEM reserve the right to introduce new contracts to the market as spin-offs of existing contracts. When a contract spin-off occurs, an original contract will be replaced by two or more new contracts which subdivide the payoff space of the original contract. For instance, the contract DEM12_WTA could be split into two contracts, DEM12_WTA_G55 and DEM12_WTA_L55, where DEM12_WTA_G55 denotes the case in which the Democratic nominee receives the most popular votes AND that the Democratic voteshare is 55% or more of the total two-party vote, while DEM12_WTA_L55 denotes the case in which the Democratic nominee receives the most popular votes AND that the Democratic voteshare is less than 55% of the total two-party vote.

No holder of the pre-spinoff contracts will be adversely affected. Traders will receive the same number of each of the new contracts as they held in the original, and the sum of the liquidation values of the new contracts will equal the liquidation value of the original.

Outstanding limit orders to buy or sell the contract which is to be spun-off will be canceled just prior to the spin-off.

Decisions to spin-off a contract will be announced at least two days in advance of the spin-off. The new contract names, the specifications regarding liquidation values and the timing of the spin-off will be included in the announcement. This announcement will appear as an Announcement on your WebEx login screen.


Contract Bundles

Fixed price contract bundles consisting of one share of each of the contracts in this market can be purchased from or sold to the IEM system at any time. The price of each fixed price contract bundle is $1.00. Because exactly one of the listed U.S. Presidential election outcomes will result from the election, the total payoff from holding a fixed price contract bundle until the market closes is $1.00.

To buy or sell fixed price contract bundles from the system, use the "Market Orders" option from the Trading Console. Select "PRES12_WTA (buy at fixed price)" from the Market Orders list to buy bundles. Select "PRES12_WTA (sell at fixed price)" to sell bundles.

Bundles consisting of one share of each of the contracts in this market may also be purchased and sold at current aggregate market prices rather than the fixed price of $1.00. To buy a market bundle at current ASK prices, use the "Market Order" option as above but select "PRES12_WTA (buy at market prices)." To sell a bundle at current market BID prices, select "PRES12_WTA (sell at market prices)."

Bundle purchases will be charged to your cash account and bundle sales will be credited to your cash account.

This market will remain open until contract liquidation. Liquidation values will be credited to the cash accounts of market participants.
