Item 8.01 Other Events

On December 21, 2009, a termination trigger occurred under the trust agreement for the MacroShares Major Metro Housing Up Shares (the " Up MacroShares"). Pursuant to Section 11.1(a)(xiii) of the trust agreement for the Up MacroShares, a termination trigger will occur if the amount of cash and treasuries on deposit in the MacroShares Major Metro Housing Up Trust (the “Up Trust”) or the MacroShares Major Metro Housing Down Trust (the “Down Trust,” and together with the Down Trust,” the “Paired Trusts”) is less than fifty (50) million dollars on any business day and MacroShares Housing Depositor, LLC (the “Depositor”) elects, in its discretion, to terminate the Paired Trusts. The amount of cash and treasuries on deposit in the Up Trust on December 21, 2009 was $10,587,338.08 and the amount of cash and treasuries on deposit on that same date in the Down Trust was $10,587,338.08. The Depositor has elected, in its discretion, to terminate the Paired Trusts.

The trust agreement provides that, following the occurrence of a termination trigger, the next scheduled distribution date will be an "Early Termination Date" on which all outstanding Up MacroShares will be redeemed at their Per Share Underlying Value (as defined in the trust agreement) as of the last Index Publication Day preceding such Early Termination Date. An "Index Publication Day" is the Business Day in each month on which the Index is calculated and published by the Reference Index Provider.

The next scheduled distribution date for the Up MacroShares is December 29, 2009, which will be the Early Termination Date. The last day of trading for the Up MacroShares on NYSE Arca will be December 28, 2009.

On January 6, 2010, a final distribution will be made on the Up MacroShares to the holders of record of those shares as of December 31, 2009. This final distribution will be based on the underlying value of the Up MacroShares Trust. The underlying value of the trust will be determined based on the November 24, 2009 release of the Reference Value of the S&P/Case-Shiller Composite-10 Home Price Index.

Authorized Participants may continue to direct paired issuances of Up MacroShares until December 28, 2009. In accordance with the trust agreement, paired optional redemptions will only be permitted if, after the redemption, the assets of the Up Trust do not fall below ten (10) million dollars.

From December 22, 2009 until the last trading date on December 28, 2009, the full amount of all incremental trust expenses of the Up Trust resulting from the Early Termination will be allocated to the Up MacroShares. This action will result in the reduction in the underlying value of each Up MacroShare of approximately $0.85 to $0.90 per share above the impact on underlying value of daily expense accruals in effect prior to December 21, 2009.

Attached here as Appendix A is the press release issued by the Depositor announcing the occurrence of the termination trigger.
