PORTFOLIO NOTE

On August 1, 2006, we announced that we will voluntarily limit the annual growth of our retained mortgage portfolio to 2.0 percent per annum. This voluntary, temporary portfolio limit is in response to a request of the Office of Federal Housing Enterprise Oversight, or OFHEO, our safety-and-soundness regulator. On September 19, 2007, OFHEO provided an interpretation regarding the calculation methodology of the voluntary temporary growth limit. The interpretation changed the measuring methodology for the growth limit from the value of our Retained portfolio, as calculated in conformity with GAAP, to the unpaid principal balance (UPB) of the Retained portfolio. Any net increase in delinquent loan balances in the Retained portfolio after September 30, 2007 will not be counted for purposes of determining Freddie Mac's compliance with the growth limit.

According to OFHEO's interpretation, the new portfolio limit for the third quarter of 2007 is $735.0 billion UPB. For the fourth quarter of 2007, the quarterly growth limit of 0.5 percent is doubled to 1.0 percent, and the 2.0 percent per annum limit remains in place. Consequently, the quarterly growth limit would be $742.4 billion as of December 31, 2007. Beginning October 1, 2007, quarterly compliance with the growth limit will be determined based on the cumulative average month-end portfolio balances beginning July 2007 (until it becomes and remains a 12-month moving average) compared to the applicable quarterly growth limit. For purposes of this calculation, OFHEO's interpretation sets the beginning value for the month of July 2007 at $725.0 billion.

We believe we are meeting the terms of OFHEO's September 19, 2007 interpretation. The current method of calculating the Retained portfolio growth limit differs from the methodology described in our letter to OFHEO dated July 31, 2006. For additional information, please see our Information Statement dated March 23, 2007 and related supplements and our letter to OFHEO dated July 31, 2006, which are available on the Investor Relations page of our website at http://www.freddiemac.com/investors.

The Retained portfolio amounts set forth in this report exclude premiums, discounts, deferred fees and other basis adjustments, the reserve for losses on mortgage loans held-for-investment, and unrealized gains or losses on mortgage-related securities and PC residuals that are reflected in the retained mortgage portfolio under GAAP. (2) Total mortgage portfolio (Table 1) is defined as Total Guaranteed PCs And Structured Securities Issued (Table 4) plus the sum of Mortgage Loans (Table 3) and non-Freddie Mac mortgage-related securities (Agency and Non-Agency) (Table 3). (3) Total mortgage portfolio Purchases and Issuances (Table 1) is defined as Retained Purchases (Table 2) plus Total Guaranteed PC and Structured Securities Issuances (Table 4) less Purchases into the Retained Portfolio (Table 5). (4) Includes: (a) sales of non-Freddie Mac mortgage-related securities from our Retained Portfolio, (b) sales of multifamily mortgage loans from our Retained portfolio, (c) net additions to the Retained portfolio for delinquent mortgage loans purchased out of PC pools and (d) balloon reset mortgages purchased out of PC pools. Excludes the transfer of single-family mortgage loans through transactions that qualify as sales (see Endnote 5) and all transfers through swap-based exchanges. (5) Single-family mortgage loans purchased for cash are reported net of transfers of such mortgage loans through transactions that qualify as sales under SFAS 140. See Endnote 4 for more information regarding the presentation of all transfers through swap-based transactions and Multifamily mortgage-loans transferred in transactions that qualify as sales under SFAS 140. (6) See Endnote 4. Also Includes sales of PCs and Structured Securities from the Retained portfolio reported as Sales out of the Retained Portfolio (Table 5). (7) Mortgage Purchase Agreements, Net reflects trades entered into during the month and includes: (a) monthly commitments to purchase mortgage-related securities for the Retained portfolio offset by monthly commitments to sell mortgage-related securities out of the Retained portfolio during the month and (b) the net amount of monthly mortgage loan purchases and sales agreements entered into during the month. Substantially all of these commitments are settled by delivery of a mortgage-related security or mortgage loan; the rest are net settled for cash. Mortgage Purchase Agreements, Net also includes the net amount of mortgage-related securities that we expect to purchase or sell pursuant to written and purchased options entered into during the month for which we expect to take or make delivery of the securities. In some instances, commitments may settle during the same period in which we have entered into the related commitment. (8) Includes PCs, Structured Securities and tax-exempt multifamily housing revenue bonds for which we provide a guarantee, as well as credit-related commitments with respect to single-family mortgage loans held by third parties. Excludes Structured Securities where we have resecuritized PCs and other previously issued Structured Securities. These excluded Structured Securities do not increase our credit-related exposure and consist of single-class Structured Securities backed by PCs, Real Estate Mortgage Investment Conduits (REMICs) and principal-only strips. The notional balances of interest-only strips are excluded because this table is based on unpaid principal balance. Also excluded are modifiable and combinable REMIC tranches, where the holder has the option to exchange the security tranches for other pre-defined security tranches. Additional information concerning our guarantees issued through resecuritization can be found in our most recent Information Statement and related supplements. (9) Represents principal repayments relating to PCs and Structured Securities including those backed by non-Freddie Mac mortgage- related securities and relating to securities issued by others and single-family mortgage loans held by third parties that we guarantee. Also includes the purchase of delinquent mortgage loans and balloon reset mortgage loans out of PC pools. (10) Represents guaranteed PCs and Structured Securities held by third parties and credit-related commitments made to third parties. (11) Single-family delinquencies are based on the number of mortgages 90 days or more delinquent or in foreclosure as of period end while multifamily delinquencies are based on net carrying value of mortgages 60 days or more delinquent or in foreclosure as of period end. Excludes securities we classify as Structured Transactions as well as mortgage loans whose original contractual terms have been modified under an agreement with the borrower as long as the borrower complies with the modified contractual terms. Previously reported delinquency data is subject to change to reflect currently available information. Generally, revisions to previously reported delinquency rates have not been significant nor have they significantly affected the overall trend of our Single-Family "Credit Enhanced" and "All Loans" delinquency rates. See Endnote 12 for more information. (12) We have modified our presentation of delinquency rates to exclude securities we issue that we have classified as Structured Transactions. Structured Transactions typically have underlying mortgage loans with higher risk characteristics but generally provide inherent credit protections from losses such as; subordination, excess interest and over-collateralization, in addition to loan level credit protection that may also exist. Additional information concerning Structured Transactions can be found in our most recent Information Statement and related supplements. The unpaid principal balance of Structured Transactions was $22.4 billion, representing approximately 1 percent of our Total mortgage portfolio at July 31, 2007. The delinquency rate for Structured Transactions was 8.7% at July 31, 2007 and principally represents credit enhanced securities. Prior periods presented have been revised to conform to the current presentation. (13) Our PMVS and Duration Gap measures provide useful estimates of key interest-rate risk exposures. While we believe that PMVS and Duration Gap are useful risk management tools, they should be understood as estimates rather than precise measurements. Methodologies employed to calculate Interest-Rate Risk Sensitivity Disclosures are periodically changed on a prospective basis to reflect improvements in underlying estimation processes.
