text: financial instruments of many types are offered to buyers . this invention is intended to cover all instruments , including deposit accounts , where a buyer purchases an instrument for a period of time at an interest rate ( fixed or variable ). an example of such instruments is the certificate of deposit ( cd ). for convenience , we will use the term cd to mean any such instrument . this term is not intended to limit the scope of this invention but only make discussion of the invention concepts easier . the term bank is also only a convenience . it is intended to mean any depository , not necessarily limited to a licensed depository such as a state or federally licensed bank , savings bank or credit union . the basic model of a depository ( such as a bank ) is to borrow money at one rate and loan it to others at a higher rate . the borrowing and loan rates are largely dictated by market forces , but some transactions are for a fixed period of time . these fixed maturity instruments can become out of sync with market reality . sometimes this is advantageous to the bank and sometimes to the customer . to the extent that the bank can have a degree of certainty over its cost of money for loaning to others , it can better predict how to price its loans . thus stability in the cost of money is key to the success of a bank . one of the most popular methods to increase bank stability at a relatively low cost is the certificate of deposit or cd . it is a somewhat unique financial instrument in that it is rather highly regulated by governmental agencies with respect to disclosures and limits on changes to the rules once issued . this creates a risk to banks in that in rising interest rate environments , the attractiveness to a cd holder to refinance ( cancel the cd with penalty and reinvest in a new cd at a better rate ) is great . for banks issuing these instruments , the early cancellation / redemption of cds causes the issuing bank to lose stability of its deposits and incur increased transactional costs . for competing banks , this is an opportunity to gain market share by taking deposits from the original issuing banks . the traditional method of stopping this outflow of capital has been fear . the regulations themselves have required the words “ substantial penalty for early withdrawal ” to be disclosed to the purchaser regardless of whether the penalty is really substantial . early withdrawal penalties discourage early redemption , but at some point the interest rate differential becomes sufficiently attractive that an informed cd holder will be tempted to redeem and reissue . to encourage redemption and re - issuance at a competitor &# 39 ; s financial institution requires a further change which will make the re - issuance clearly advantageous : the re - issuer should preferably provide that the term of the new ( re - issued ) cd from the new institution will expire on the date of the original cd or a time reasonably close thereto , such as the beginning or end of a month of the original term , or exactly on the date of the original term . the effectiveness of the penalties in holding the cds during a rise in rates is a function of the penalty structure , rate and remaining term . ignoring the present value impact , the general effectiveness of penalties can be calculated by : examples therefore include : a 3 % cd with a 6 - month early withdrawal penalty and 2 years remaining has protection for a 75 basis point increase in yields . a 3 % cd with a 3 - month penalty and 3 years remaining has protection of 25 basis points . a 3 % cd with an 18 - month penalty and 3 years remaining has protection of 150 basis points . cd yields vary over time for any bank . banks adjust the interest they pay on cds for many reasons . deposits represent a major portion of the funding source for banks . by increasing interest rates offered on deposits banks seek to attract more funding and by lowering interest rates offered on deposits they seek to lower funding costs . banks may adjust rates for many factors including local deposit competition , national interest rate markets , investment opportunities and loan demand . cd yields vary materially between banks . historical surveys of interest rates offered on cds reveal significant variances between banks . on jun . 1 , 2006 a survey was done of 3 - year cd offerings posted on the web sites of the current largest 12 issuers of fdic - insured time deposits . offerings were not posted on the web sites for all of these banks . it is likely that banks tend to post offerings they believe are attractive and withhold offerings they do not consider attractive . one might assume that the offerings not posted were relatively low . of the banks who did post their rates , the yields on their 3 - year cd offerings varied from 3 . 26 % to 5 . 25 % annual percentage yield . there was 199 basis points of difference between the lowest and highest observed apy for the exact same investment offered from two of the top issuers in the u . s . on that day . the highest yield observed was 61 % higher than the lowest . cd yields may vary materially within individual banks by term . of the banks surveyed one of the banks offered an 11 - month cd paying 3 . 45 % apy while their 12 - month cd was offered at 4 . 95 % and the 12 - month had a special bump feature to enhance it . this 150 basis point differential was not supported by the slope of the yield curve from 11 - months to 12 - months . the rate differential attributable to the yield curve as defined by the london interbank offering rate was less than 2 basis points . yield differentials between currently outstanding deposits or presently offered cds and presently offered high - yielding cd alternatives provide an opportunity for depositors to enhance the value of their investments while remaining in safe and secure fdic - insured investments . to accelerate the transition to higher yielding cds a customized monetary measure of the financial impact will allow depositors to more effectively respond to the opportunities that currently exist for them . this invention clearly identifies the monetary impact opportunity that apy alone does not . due to the structural differences between compounded cds and cds which are not compounded the basis of comparison is different between the two . for compounded cds the value at maturity is the best basis of comparison for an original and a customized cd alternative designed to mature on the same date . due to the accumulation of value into the total current account value at maturity of both cds a comparison of the two values at maturity will clearly identify the preferred investment and define the amount of competitive advantage of the preferred investment . fig3 and 4 illustrate the effect of compounding on when the “ break point ” ( the point at which issuing a new cd is advantageous . the figures use sample data for illustration of the concept . the break point is shown by virtue of the change in font or color in the figures . cds which are not compounded can be compared by considering future earnings of the two investments less the amortized cost of any applicable early withdrawal penalty associated with re - issuance of any outstanding cd applied to the re - issued cd . the opportunity to create a net benefit to transfer an existing certificate of deposit depends upon the amount of the deposit ; the current yield ; the amount of time remaining before maturity ; the early withdrawal penalty ; and the new market - rate yield available for the remaining term . the result is a net benefit to transfer . compounding can also play a factor in whether there is a net benefit to the customer . a compounded cd reinvests the interest in the cd and generates additional gain at maturity . therefore , if a customer were to replace a non compounding cd with a compounding one , a smaller interest rate differential ( between new and old rates ) might create a sufficient net benefit to the customer to redeem the first cd in favor of a new one . by creating a data table of alternative refinancing dates and refinancing rates , potential scenarios can be evaluated and compared to the current net benefit to transfer opportunity . for each unique cd this table presents a differential analysis between results of refinance date and rate combinations . in other words you can determine from a quick analysis of this table how much rates must rise as time passes to maintain or improve the refinance opportunity . one can also identify the amount the opportunity diminishes as time passes without rate changes or with rate reductions . the optimal time to refinance is dependent upon actual available market rates of interest over the remaining life of the deposit . a depositor can highlight in the data table their forecast of rates at the intersection of date and rate for each remaining date of the cd . under the rate scenario defined by this exercise the optimal refinance date is determined by selecting the date that has the highest highlighted positive net benefit to transfer . caution should be taken in interpreting any results based upon interest rate forecasts . fig1 illustrates general flow of interest rates over the most recent 29 year period . at the time of this writing interest rates appear to be headed for a general rise . this will make the applicability of this invention even greater as cds issued in a lower interest rate environment have or will become vulnerable . one feature of the present invention is to offer a reissue cd to the current cd holder which is customized to the date of expiration of the current cd . with this feature , the redeemer can more clearly compare the benefit of the bargain for re - issuing and will also be able to maintain whatever financial plan they created when the original cd was purchased . for example , a party may purchase a cd to expire at the time a loan balloon ( on some other loan ) will come due , or other financing need . if the re - issued cd would have to restart the holding period , and the expiration date would , only by chance , be the same as the depositor &# 39 ; s need for the funds . notice also , that while i have discussed the invention in terms of cd &# 39 ; s , it is also applicable to instruments like mortgages , and other time fixed instruments , where the holder may wish to re - issue but not extend the financing term . for example , a 30 year mortgage , if re - issued after 10 years and 27 days , may only be available in 10 , 15 and 30 year increments , but according to the invention , it could be re - issued for the exact remaining term as the original instrument . thus a party can continue to re - issue its cds or other instruments and still be assured that the expiration / maturity date will remain fixed , thereby reducing one of the complicating impediments to redemption and re - issue . for the purpose of attracting new cd funds one method of calculating whether it is desirable to re - issue the cd is determining ( or calculating ) the total ( unaccrued ) current account value of a first cd as of a predetermined calculation date . the total current account value amount is that portion of the cd which would generate revenue in the future from the calculation date to normal maturity . determining the contractual penalty for early withdrawal on said predetermined date . this is usually a clause in the issuing contract . calculating the net cash value of the first cd on the predetermined calculation day by determining its total current account value and subtracting the penalty from said value . this is the net cash value which a cd redeemer would expect to receive in hand . it is also the typical starting investment in the second ( re - issued ) cd . creating a customized second cd , using the net cash value as initial investment , having an expiration date generally equal to the expiration of the first cd , interest handling features of the first cd and a current rate of interest offered by the re - issuing bank ; the expiration date does not have to be exactly the same . for example , the end or the beginning of the month of the original cd might be convenient for the holder . it could be longer or shorter if that was deemed a marketing advantage , such as offering an greater interest rate for a longer term or a shorter term and a lower interest rate as an incentive to a holder who can &# 39 ; t hold for the original term but can be maintained as a customer on a shorter term instrument . in such case , the bank retains a customer and does not lose the capital . the interest rate can be at “ market ” which might be the prevailing rate on that date for the bank or some other market rate calculation . it can also be above or below market so long as there is some incentive for the holder to re - issue to that bank . creating a customized analysis which identifies the financial advantage of the second cd compared to the first even after accounting for the early withdrawal penalty of the first cd ; and issuing said second cd to the owner of the first cd using said initial investment or , at the bank &# 39 ; s option , at a higher or lower initial investment . if lower , the holder gets cash back or cash out at the re - issuance , which could be a significant advantage . if the analysis fails to justify the current re - issuance the bank seeking the re - issuance sends the potential depositor a thank you and an analysis of the current differential in potential financial results over the term of the cd under consideration if transferred at maturity for a new term that matches the current term of the cd . this is accomplished by comparing the currently quoted yield on the depositor &# 39 ; s current term at the current bank of deposit and the yield available from the bank seeking the re - issuance for the same term . if the original cd goes to maturity at the original bank , the bank seeking the deposit sends a fresh offer to attract the transfer at maturity . this offer would be timed a few weeks before maturity and would present an offer that could be redeemed anytime through the grace period of the maturity of the original cd . when a financial institution seeks such re - issuances , it also creates the side effect that the purchaser is now much more savvy and more likely to re - issue the certificate again as soon as interest rates dictate . the present invention contemplates this condition and deals with it in a number of ways . first , the bank does not need to provide the re - issued instrument with the same withdrawal penalty rules . the bank will offer a standard early withdrawal penalty appropriate for the term of each cd . depositors may request an alternative early withdrawal penalty for the new account . the concept of a plurality of alternative penalty options for the cd issuer to offer also forms a portion of this invention in one embodiment . the depository may make available other penalty options subject to alteration of the interest rate , apy and the net benefit to transfer . although standard early withdrawal penalties will be set by term to maturity , alternative penalties will be available with compensating interest rate and apy adjustments . more significant penalties will generally allow the bank to issue higher apy . conversely , less significant penalties will be compensated for with lower apy offerings . the present invention includes computer code to carry out the method of calculating the optimal time to re - issue . instead of discouraging a customer from re - issuing , in one embodiment the bank may include a notification feature which advise the customer automatically when re - issuing would be profitable . computer code would monitor current interest rates and penalty scheme of the cd and when there was justification for a re - issue , notify the cd holder . ( justification would be , at a minimum when the reissued cd would have a total future interest accumulation at least as great as the current cd &# 39 ; s remaining term , taking the penalty into account ). of course , the justification will increase as the new cd &# 39 ; s accumulated interest further exceeds the benefit of doing nothing . in one such embodiment there is a method of retaining cd customers during periods of rising interest rates by : at periodic intervals ( for example , daily ), calculating the total account value on the calculation date . calculating the contractual penalty for early withdrawal on said calculation date ; calculating the net cash value proceeds of the cd on the calculation date by subtracting the penalty from the total current account value ; consider a customized second cd , using the current net cash value as initial investment , having an expiration date generally equal to the expiration of the first cd , interest handling features of the first cd and a current rate of interest offered by the bank ; creating a customized analysis which identifies the financial advantage of the second cd compared to the first even after accounting for the early withdrawal penalty of the first cd ; and comparing said total value at maturity of the first cd with a second cd issueable on calculation date from net proceeds of the first cd at an interest rate selected by the issuer having a term expiring generally equal to the term of the first cd ; ( of course , the terms could vary , per above ). if the customized analysis identifies a financial advantage of the second cd , compared to the first cd , then notify holder of the first cd that a second cd is available which will outperform the first cd despite the penalty for early withdrawal ; ( notification could be by phone , email , fax , rss , or means not yet invented and offering the customer said second cd having an expiration date generally equal to the first cd ( or with some other expiration date and with a possible cash out option , per above ). while it would seem illogical to remind customers of the possibility of a reissue , one must assume the customers who have already been influenced by the possibility of reissue , will do so again , and failing to provide this information simply opens the door for a savvy competitor . the objective is to hold one &# 39 ; s customer base and not have it taken away by a competitor . the cost of re - issuing a cd ( or other instrument ) to an existing customer is far lower than the cost of finding a new customer to do so . the actual negative impact to the bank would be minimized if the depositor refinanced the bank &# 39 ; s own cds every time the refinance was marginally beneficial . if a depositor waits for more material interest rate increases the detrimental impact to the bank increases . encouraging the customer to refinance promptly when a positive net benefit to the customer occurs creates customer loyalty and benefits the bank in the long - run simultaneously . the present invention , in one embodiment , includes several means for maintaining customer loyalty . another embodiment could discourage reissuance by a competitor by offering an interest rate which is more attractive ( i . e . greater ) than market rates . the bank could only offer such a rate if was compensated by other factors , such as greater interest forfeiture on early redemption or holding a call or conversion option . if the depositor seeks additional yield the depository may provide a premium yield option by the bank retaining a call or conversion option . appropriate disclosures will be used to communicate the risk and reward of this premium yield option . the bank is rewarded for issuing a premium yield cd if the cd is callable so that the risk is limited . a conversion feature would have a similar effect . since cd offers are not currently customized by potential transaction , there is no need to track individual bank offers . with customized offerings on the basis of amount , term , rate / apy , early withdrawal penalty , call features and other potential details , the bank will need a tracking / reservation system to provide a method of honoring customized quotations for a reasonable period of time to allow for delivery of the funds . we will refer to this as a quote reservation system wherein the bank will keep a data base of customized offers it has made to customers , most of which will expire in 30 - 60 days at which time they may be purged from the quote system . to enhance renewal at maturity the bank could waive early withdrawal penalties for immediate renewal . this latter inventive concept is particularly desirable by providing a pathway for the incumbent bank ( the current issuer ) to hold onto the customer by offering an early redemption before the normal expiration date with a minimal penalty ( or by waiving the penalty altogether ) in lieu of the sale of a new instrument of greater length . by this means , the incumbent bank gets a “ jump ” on the competition by interceding through offering to reissue the cd before the customer has begun to look at options from competitors . this method is particularly useful where customer loyalty and continuity is prized by the bank . in fig2 , one embodiment of the present invention is illustrated : typically , the depository institution ( i will call bank , as broadly defined ) encourages current time deposit holders to contact them to determine the magnitude of their current financial opportunity ( 500 ). when contacted , the bank requests that the deposit holder give them consent and authorization to investigate the existing parameters of each of their time deposits or that the depositor provide this information for the required analysis from their own records or research ( 510 , 512 , 514 ). this is preferable since it allows the bank flexibility in response , as will be indicated below . if the depositor agrees , the path along block 520 is selected , otherwise , the path along block 516 is followed . in the later case , the depositor makes contact with his / her bank ( 517 ) and provides this information to the new bank ( 518 ). this is not preferred because the depositor is subject to influence by the originally issuing bank and the data provided may be sufficiently confusing so as to stop a possibly beneficial transaction , or the original bank may capture the reissue ( one preferred embodiment which prevents a loss of funds at said original issuing bank ). in the alternative case ( 520 ), the depositor authorizes the new bank to obtain the necessary data and make an offer ( net benefit to transfer — nbtt ) ( 522 , 524 , 526 , 528 , 529 ). the new bank is entitled to provide marketing data to the customer to try to influence their decision , but the factual data must be exact so to not run afoul of banking law or securities regulations of the territory . the bank offers a customized time deposit based on the dimensions of the existing deposit . in one embodiment , the new account deposit amount will be same as the current funds available from the existing time deposit account after paying any applicable early withdrawal penalty . in another embodiment , the deposit amount can be less . for example , in a rising interest rate environment , the new cd will produce enough interest income in a shorter length of time ( relative the original cd ) that the bank can achieve the same total interest over the life of the cd that the initial capital investment can be reduced . one option is for the customer to keep cash at reissuance , in the amount of this differential . the alternative is that that cash amount would be retained as part of the capital investment and the interest accrued will exceed that of the original cd . in one embodiment , the expected new account maturity date will match the existing deposit next maturity date . the expected method and timing of paying interest or compounding will be the same as the current deposit account . the offer will be based on the new depository &# 39 ; s standard early withdrawal penalty structure . this standard penalty need not be at all like the prior penalty , whether this is a reissue from the same bank or a competitor . indeed , having a stiffer penalty which will diminish the incentive to reissue optionally coupled with ( alternatively ) a higher rate as an enticement , may keep funds in place longer despite rising interest rates . the bank provides a customized analysis of the net benefit to transfer as well as the apy of the new investment and all other regulation dd requirements ( 526 ). the customized net benefit analysis will monetize the benefit of withdrawing and transferring the funds to the new depository . in the event of a positive nbtt , the depositor withdraws early ( 530 , 532 ), the penalty is paid and the new cd is issued , usually for the remaining term of the original cd . if the nbtt is not sufficient to warrant an early withdrawal and transfer , ( 534 ), the transfer authorization is cancelled ( 536 ) or the new bank can request authorization for transfer of funds anyway , ( 538 ) such as if there are other benefits for the transfer , such as an above market interest rate with call features retained by the bank as an enticement to the depositor to switch to the new bank . this may be advantageous to the new bank because of the value of brand ( bank ) loyalty . in such case , the bank makes the transfer or offers a quotation to the depositor with an expiration period , ( reservation of time ) 540 . if completed 542 , the new cd is issued . if not , because of expiration , ( 544 ), the bank advises the depositor ( 550 ) but may maintain the contact name in its data base to make contact at a time approaching the original expiration date ( 552 ). this last step is particularly useful in capturing a customer who obtains a free analysis of his / her cd and may have a higher trust level in the new bank . if the new bank promises to provide such analysis even on its own cd &# 39 ; s , the customer would have a strong incentive to switch issuers at the next opportunity ( expiration ). the invention envisions that alternative early withdrawal penalties may be an option , either at the request of the holder or the bank . the holder may also be encouraged to add to the initial investment by adding principal to the starting deposit of the reissued cd . this may allow the bank to offer some reciprocal advantage to the depositor such as higher interest rate , relaxed withdrawal penalty , etc . one variation of the invention is cash out option . this is accomplished simply by not reinvesting all the cash available after the withdrawal . instead the depositor invests only the amount needed to create the same future value as the original cd . the remainder becomes the immediate cash reward ( cash out ). this option creates immediate gratification . the investor has fresh cash in their pocket and realizes the original cd &# 39 ; s investment value at maturity . the depository using the invention would prefer that the depositor not take this option because it reduces the deposits . another aspect of the invention is the creation of a premium yield option . if the customer will accept a greater penalty for early termination / withdrawal the bank has greater assurance that the funds will remain on deposit for the full term of the cd and will therefore be willing to offer a higher interest rate . therefore , in one embodiment , the prior cd is redeemed and a replacement cd is issued , the penalty term of the replacement cd may be greater than the original cd early termination penalty . in such case the interest rate offered on the replacement cd will be greater than the rate which would have been otherwise offered if the penalty was equal to or less than the penalty of the original cd ( such as the market rate . another aspect of the invention involves a call or conversion option . in the event that interest rates decline , it may be advantageous for a bank to call the cd and force redemption or other forced conversion . the other conversion may also be the forced issuance of a new deposit account at a lower rate . customers may be willing to accept such a feature especially if the interest rate is increased over the market rate to justify the additional risk to the customer and the decreased risk to the bank . another aspect of the invention relates to a maturity monitoring marketing list database system . if a current cd customer or a future customer prospect owning cds at another financial institution , is known to the bank , it would be possible to enter the customer &# 39 ; s contact information with knowledge of the customer &# 39 ; s current cd portfolio . when market conditions dictate the customer can be offered a replacement cd product offering which may have an expiration date coterminous with the customer &# 39 ; s current cd . for international customers , a change in interest rates between different currencies may trigger a market opportunity to convert a cd in one currency to another , where the market rate on that currency may be advantageous ( i have no basis to defend the validity of this statement ). this “ maturity monitoring marketing list database ” which would monitor the maturity of off site cds ( or other time deposit monies ) would put the bank in a position to gain early access to customers before their current institution contacts them for renewal . as part of the maturity monitoring marketing list database system or independent thereof , the bank could obtain a transfer authorization simultaneously with entry of the customer into the bank &# 39 ; s data base of prospective customers with cds from other institutions . if the bank holds legal authorization form the customer , then an offer of a replacement cd to the customer can be executed upon a verbal , email or other simple customer instructions . of course the bank will want to use a method of verifying the existence and / or authenticity of the instruction , such as by a verification parameter ( social security number in the us or other alphanumeric codes , ip address , etc .) or biometric data ( voice print etc ).
