One of the major changes is the rate spread calculation.
See Appendix A. This text is on Page 17 of 24 page document.

1. Rate Spread.
a. For a home purchase loan, a refinancing, or a dwelling-secured home
improvement loan that you originated, report the spread between the annual
percentage rate (APR) and the applicable Treasury yield if the spread is equal to
or greater than 3 percentage points for first-lien loans or 5 percentage points for
subordinate-lien loans. To determine whether the rate spread meets this threshold,
use the Treasury yield for securities of a comparable period of maturity as of the
15th day of a given month, depending on when the interest rate was set, and use
the APR for the loan, as calculated and disclosed to the consumer under section
226.6 or 226.18 of Regulation Z (12 CFR part 226). Use the 15th day of a given
month for any loan on which the interest rate was set on or after that 15th day
through the 14th day of the next month. (For example, if the rate is set on
September 17, 2004, use the Treasury yield as of September 15, 2004; if the
interest rate is set on September 3, 2004, use the Treasury yield as of August 15,
2004). To determine the applicable Treasury security yield, the financial
institution must use the table published on the FFIEC's web site
(http://www.ffiec.gov/hmda) entitled “Treasury Securities of Comparable
Maturity under Regulation C.”
b. If the loan is not subject to Regulation Z, or is a home improvement loan that
is not dwelling-secured, or is a loan that you purchased, enter “NA.”
c. Enter “NA” in the case of an application that does not result in a loan
origination.
d. Enter the rate spread to two decimal places, and use a leading zero. For
example, enter 03.29. If the difference between the APR and the Treasury yield is
a figure with more than two decimal places, round the figure or truncate the digits
beyond two decimal places.
