Original Issue Discount (OID) and Market Discount Fraction (MDF) values are provided by Issuers of Ginnie Mae-guaranteed securities and Ginnie Mae will post them to the website as received. While Issuers are required to report OID and MDF accurately on a monthly basis, if necessary, corrections to values reported for the previous calendar year may be made in January. On January 31, all data for the previous calendar year is considered final and can be used for tax reporting purposes. Please note that the OID and MDF on GNMA II multiple issuer pools are blended values.
