i20a APRChecker® and Dealer Reserve
WebService Product Features
Fast, accurate & reliable calculations
The i20a WebService provides fast, accurate, and fully-featured validation
calculations to any user with a browser and internet connection. This
includes not only PC's runing Windows, but also Apple or Linux systems, as
well as many handheld devices which have a web connection.
The i20a WebService uses formulas and algorithms that have been in use for
over 30 years -- you can count on the same reliable and correct calculations
that you have received from other PROM Software products over the years.
Moving these calculations to a web-based platform is the next logical step in
providing our services to the financial and insurance industries.
PROM's i20a WebService is hosted at redundant sites in data centers with
Easy to use, works with any browser
One of the biggest advantages of PROM's i23a WebService is that it works on
any internet browser. It doesn't matter whether it's on a Windows PC, Apple,
Linux, PDA, or a front-end or back-end system. There's no special training
required for end-users.
Virtually no maintenance costs
Two other major advantages of the PROM i20a WebService is that it virtually
eliminates any maintenance costs for you. Because no software is installed on
client PC's, there's no need to maintain the software throughout your
Even if PC software is "free" there is a significant maintenance effort and
associated cost in maintaining the software and required hardware.
Upon an update to the "free" PC program, all PC's have to be tracked down and
updated. If some are missed, they will continue to run the old version, likely
producing incorrect results. It is quite often very hard to find all the
installations that need to be updated.
If you're using the i20a WebService and a change in the calculations becomes
necessary (due to a regulation change for example), the i20a WebService
is updated on our webhosts at the appropriate time.
From that point forward, ALL clients will be running the new version.
Unlimited number of users, no per-copy license hassle
Because our i23a WebService is delivered over the internet, you can give an
unlimited number of users in your organzation access to the service. There is
no 'per-seat' licensing and none of the associated complicating issues such
as restrictive copy-protection schemes that often fail to work easily or
As a WebService client, you're free to use the service on any PC or system
you want, and you can change or update any system without having to
uninstall, reinstall, obtain a new license, and so forth. Your employess can
use the service from home or in your customers' offices. If you're an
indirect lender, you can allow your dealers to access the system to get
(Access to the i20a WebService is protected by a User Name and password to
prevent unauthorized use. You can change the password from time-to-time if
you want, and you can have different User Names and passwords for different
WebServices -- for example for use in different states where the credit
insurance plan varies.)
Dealer reserve (participation) and buydown
If you specify a 'buy rate' (the lender retention rate), the i20a WebService
will calculate the dealer reserve.
If the buy rate is greater than the loan
interest rate, the dealer buydown payment will be calculated (the amount the
dealer has to remit to the lender in order for the lender to maintain their
Qualifies as a Reg Z calculation tool
There are benefits to an institution under Regulation Z when they use a
calculation tool both from the perspective of disclosure violations and of
meeting the requirement to use an alternate tool to verify calculations.
Footnote 45d to Section §226.22(a) of Regulation Z states:
"An error in disclosure of the annual percentage rate or finance charge shall
not, in itself, be considered a violation of this regulation if: (1) The
error resulted from a corresponding error in a calculation tool used in good
faith by the creditor; and (2) upon discovery of the error, the creditor
promptly discontinues use of that calculation tool for disclosure purposes
and notifies the Board in writing of the error in the calculation tool."
And Section 1305.14 of the Examination Handbook (January 2004) of the Office
of Thrift Supervision states:
"When a financial institution claims a calculation tool was used in good
faith, the financial institution assumes a reasonable degree of
responsibility for ensuring that the tool in question provides the accuracy
required by the regulation. For example, the financial institution might
verify the results obtained using the tool by comparing those results to the
figures obtained by using another calculation tool."
XML output available for system integration
PROM's i20a WebService can generate XML output which makes it very easy to
incorporate its calculation ability into other computer systems.
The i20a WebService Engine can be called directly (without having to go
through a HTML form) using GET and POST protocols.
This option enables a back-end system, website, or document generation system
to use the highly accurate calculations of the i20a WebService product.
Operation is transparent and seamless to the end-user.
Validates installment loans with varying first periods, prepaid finance charges
and can calculate the dealer reserve for indirect loans.
Various mathematical checks are performed on the loan disclosure to make sure there
are no arithmetic errors. The A.P.R. and Military A.P.R. are calculated and compared
with the disclosed values to see if they are within 1/8%.
Filing fees (fees
paid to public officials) are available -- these fees are added to the loan
amount and become part of the amount financed.
Fees (other) are available. These are added to the loan amount and become part of
the amount financed, and also affect the calculation of the Military A.P.R.
Loan fees (prepaid
finance charges) are available. It becomes part of the finance charge and affects the Annual
Loans up to $100,000,000 and more can be accurately calculated. The formulas
and algorithms used in PROM's i20a WebService engine have been developed and in
use for more than 30 years, and have calculated millions of loans. The
i20a WebService engine is written in a high-level compiled language (C++)
which maintains a very high degree of accuracy and precision to
16 significant digits.
The dealer reserve or buydown calculation is done by any of three methods:
in Charges, Present Value, or Pro-rate.
A minimum dealer reserve amount can be specified. First the dealer reserve
is calculated and, if it is less than the minimum amount, the minimum
amount is shown. Default is no minimum. (Note: The dealer buydown feature
does not work if a minimum reserve is specified.)
A percentage paid can be specified. It is a fairly common practice to pay
only a percentage of the dealer reserve to compensate the lender for the
expected early terminations. Rather than issue a chargeback for a portion
of the dealer reserve paid on a terminated loan, the lender just pays a
percentage of the dealer reserve (commonly 70% - 80%) on all loans. Default
