Subject: Compliance Software
Description: Release of APRWIN 5.0 and APY 1.02  
Date: August 26, 1998

TO:  Chief Executive Officers and Compliance Officers of all
National Banks, Department 
          and Division Heads, and all Examining Personnel


APRWIN

The Office of the Comptroller of the Currency (OCC) has released
APRWIN version 5.0, which is the Windows version of the OCC's
Annual Percentage Rate Program.  A copy of the software is
available for download from the OCC's Web site at
http://www.occ.treas.gov/useful.htm.

The program is an efficient tool for calculating Annual
Percentage Rates (APR) and reimbursement adjustments when
required by the Truth in Lending Act (TILA).  It incorporates the
revised tolerances for loans secured by real estate or a
dwelling.  Earlier DOS versions of the program accurately
calculate APRs and may continue to be used.  They do not,
however, take into consideration the revised tolerances for loans
secured by real estate or a dwelling.  Beta versions and version
4.0 of the program may contain errors and should not be used to
test for compliance with the TILA. 


APY 

An error has been identified in an earlier version of the APY
program.  In some cases when the deposit term exceeds one year,
the calendar routine in APY version 1.0 calculates the incorrect
number of days in the term.  This problem was corrected in
version 1.02.  A copy of the software is available for download
from the OCC's Web site at http://www.occ.treas.gov/useful.htm.


Year 2000

Both APRWIN and APY have been tested for compliance with Year
2000 requirements and found to function correctly with respect to
the century transition.  The programs use a four-digit year code
and our tests found them to be Year 2000 compliant.

For our purposes, Year 2000 compliant means that the programs are
no more likely to produce logical or arithmetical inconsistencies
when dealing with dates beyond December 31, 1999, than  when they
use December 31, 1999, and prior dates.  The APRWIN and APY
programs met this standard during our tests.  

The OCC is not a vendor of computer software.  It developed the
APRWIN and APY computer programs to assist national bank
examiners in evaluating compliance with the TILA and the Truth in
Savings Act.  The OCC has made the programs available to others. 
They are provided without warranty, expressed or implied.  As
with other software that you use, the OCC recommends that they be
tested within the user's computer environment to ensure that they
work correctly with your equipment.

Additional copies may also be ordered from the Comptroller of the
Currency, PO Box 70004, Chicago, IL 60673-0004.  The cost of each
program is $20.

Questions about Truth in Lending and Truth in Savings should be
directed to your supervisory office.  Questions about the
programs may be directed to the supervisory office or Community
and Consumer Policy at (202) 874-4428.
