On August 1, 2006, we announced that we will voluntarily limit the annual growth of our retained mortgage portfolio to no more than two percent above the level at June 30, 2006, effective July 1, 2006. This voluntary, temporary growth limit is in response to a request of the Office of Federal Housing Enterprise Oversight, or OFHEO, our safety-and-soundness regulator. We believe we are meeting the terms set forth in our letter to OFHEO dated July 31, 2006. Our preliminary estimate of our retained mortgage portfolio, as calculated in conformity with GAAP, may change as we complete the process of closing our books for 2007. In addition, our current estimates could change as a result of subsequent events or changes in estimates.

The "Retained portfolio" balances set forth in Table 2 and Table 3 of this report represent unpaid principal balances, which are statistical measures that differ from the balance of the retained mortgage portfolio as calculated in conformity with GAAP. 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. For additional information, please see our Information Statement dated March 23, 2007 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.

ENDNOTES (1) Ending balances and activity are based on contractual amounts of unpaid principal balances and exclude mortgage loans and mortgage- related securities traded, but not yet settled. Previously reported amounts have been revised to conform with the current period presentation, which excludes the effect of credit-related impairments on mortgage-related securities in our Retained portfolio. (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 and (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 6) and all transfers through swap-based exchanges. (5) In March 2007, we improved our method for estimating remittances for PCs and Structured Securities held in the Retained portfolio. As a result of this change, the liquidations on Table 1, Table 2 and Table 4 for March 2007 were reduced by $1.3 billion. Absent this change, the growth rates for the month of March would have been 17.3 percent, 6.2 percent and 14.6 percent, on Table 1, Table 2 and Table 4, respectively; and the liquidation rates would have been 18.4 percent, 22.6 percent and 16.0 percent, respectively. (6) Single-family mortgage loans purchased for cash are reported net of transfers of such mortgage loans though 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. (7) 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). (8) 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. Mortgage Purchase Agreements, Net balances from October 2006 through January 2007 have been revised by amounts up to $329 million to correct for certain commitments related to the Retained Portfolio. (9) 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 and interest and principal classes, where the holder has the option to exchange the security tranches for other pre-defined security tranches. Additional information concerning our guarantee issued through resecuritization can be found in our Information Statement dated March 23, 2007. (10) 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 that we guarantee (see Endnote 11 for more information). Also includes the purchase of delinquent mortgage loans and balloon reset mortgage loans out of PC pools. (11) Includes, as of March 31, 2007, (a) our guarantees of the payment of principal and interest on $6.1 billion unpaid principal balance of (1) multifamily mortgage loans that are originated and held by state and municipal housing finance agencies to support tax-exempt multifamily housing revenue bonds and (2) tax-exempt multifamily housing revenue bonds that support pass-through certificates issued by third parties; and (b) our credit-related commitments with respect to $2.6 billion unpaid principal balance of single-family mortgage loans held by third parties. (12) Represents guaranteed PCs and Structured Securities held by third parties and credit-related commitments made to third parties. (13) Single-family delinquencies are based on the number of mortgages 90 days or more delinquent or in foreclosure while multifamily delinquencies are based on net carrying value of mortgages 60 days or more delinquent or in foreclosure. Includes delinquencies on mortgage loans where the lender or third party retains the largest portion of the default risk as well as certain Structured Securities. Excludes 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. For example, delinquency data reported for some Structured Securities may be omitted or subsequently revised by servicers of the underlying loans, which may require revision to previously reported numbers. For periods presented in this report, 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. Delinquencies on mortgage loans underlying alternative collateral deals may be categorized as delinquent on a different schedule than other mortgage loans due to variances in industry practice. (14) 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.
