from market history analyzer 115 . product matrix generator 125 processes and analyzes the information to provide a solution for the adapted stochastic differential equation . product matrix generator 125 may be coupled to price information generator 130 and configured to provide the solution thereto . based upon the solution it receives from product matrix generator 125 , price information generator 130 may provide data representing a product price at an output in one implementation . in an embodiment of the fuel offering generator , the price information generator 130 may also provide data representing price sensitivity at an output . in one implementation , the price sensitivity may indicate price sensitivity not only with respect to wholesale fuel markets but also with respect to retail fuel prices , and / or with respect to other input variables received from real - time market parameter generator 408 , market history analyzer 405 , and / or product modeler 420 . in one embodiment , the system 100 further comprises a product modeler 120 . product modeler 120 is coupled to at least one computer system 102 . in some embodiments of the fuel offering generator , the product modeler 120 is coupled to two computer systems 102 and 104 . in embodiments of the fuel offering generator at least one of computer systems 102 and 104 comprises a fuel offering purchaser computer . in some embodiments the fuel offering purchaser computer may be coupled to product modeler 120 via a communications network , such as the internet . a fuel purchaser may enter information related to a fuel product , such as a fuel offering , using the fuel offering purchaser computer . the fuel offering purchaser computer transmits the information to product modeler 120 . in one implementation , the product modeler 120 may use the information from the fuel offering purchaser to determine features of a financial product to be modeled by product modeler 120 . in one embodiment , the fuel offering generator 100 comprises at least one distributor computer system 104 . distributor computer system 104 is coupled to product modeler 120 and may enable a distributor to define characteristics of a financial product comprising fuel offerings to be offered to a consumer . in that embodiment a distributor inputs data to distributor computer 104 . distributor computer 104 provides the data to product modeler 120 . product modeler 120 models the financial product in accordance with the characteristics provided by distributor computer system 104 . product modeler 120 is

of a financial product . system 100 determines the price of the financial product based upon product data provided by product modeler 120 , real - time market parameters provided by real - time market parameter generator and on historical market data provided by market history analyzer 115 . in one embodiment of the fuel offering generator , the matrix generator 125 is coupled to a consumer behavior modeler 170 . consumer behavior modeler 170 receives data representing purchaser ( e . g ., consumer ) behavior with respect to fuel offering execution and / or purchase , ownership , exercising , and / or the like . based upon the behavior data consumer behavior modeler 170 provides purchaser and / or consumer behavior parameters to matrix generator 125 . in that embodiment , matrix generator 125 considers the purchaser and / or consumer behavior in calculating price for a financial product . fig1 b describes one embodiment of a fuel offering generator 101 . in one implementation of the fuel offering generator , a fuel offering comprises a product related to future purchases of fuel in a retail fuel market . both the retail and the wholesale fuel markets are observed 103 . observable wholesale fuel market parameters include wholesale fuel over - the - counter ( otc ) options information , wholesale gas over - the - counter ( otc ) forward market data in a wholesale fuel market . fuel market data including retail fuel spot price information is obtained 103 . market parameters related to current market conditions are generated based on the observed fuel market condition 111 . at least one generated market parameter related to current market conditions is wholesale - retail spot price spread in one implementation . other generated market parameters may include a wholesale implied volatility and a wholesale forward curve . in one embodiment of the invention parameters related to current market conditions are sampled and stored to provide historical data describing past market behavior 113 . one sampled and stored parameter used in one implementation to provide historical data is retail fuel market spot price . thus historical data related to retail fuel spot price is acquired . historical data , such as data related to retail fuel spot price , may be analyzed 119 . the analysis may , in one implementation , consider retail fuel market information . the data is used to estimate parameters of models for fuel market behavior 121 . examples of generated fuel market behavior parameters may include retail implied volatility , wholesale mean reversion , retail forward curve and retail mean reversion . the indicators of fuel market behavior and the parameters related to current market conditions are analyzed 123 . in one embodiment of the fuel offering generator , the analyzing step is carried out by stochastic modeling . price information for the fuel offering is generated 143 . in one embodiment of the fuel offering generator , price sensitivity information related to the fuel offering is generated 144 . in further embodiments of the invention purchaser and / or consumer behavior may be observed 141 . data related to purchaser and / or consumer behavior is obtained based on the observations . in one embodiment of the invention purchaser and / or consumer behavior data is analyzed 142 as considered in an analyzing step 123 as a factor in generating price information 143 . with reference now to fig2 , there are shown and described a top level information flow of a process for creating and managing the execution of fuel offerings to one or more purchasers , according to one embodiment . fig2 is seen to include three principal parties including a provider 202 of fuel offerings , a distributor 204 of fuel offerings and at least one purchaser 206 of fuel offerings . it will be understood that in certain embodiments , the provider 202 and distributor 204 may be considered as a single entity from the perspective of the purchaser 206 . it will also be understood that while fig2 illustrates a single purchaser 206 , for ease of explanation , the single purchaser 206 is representative of a marketplace of potential purchasers 206 of the fuel offering . at block b 1 , a request is made by the distributor 204 , directed to the provider 202 , to structure and / or generate one or more fuel offerings . in some embodiments , the request may include some number of product factors and / or parameters , for example , ( i ) the type of fuel to offered , ( ii ) the quantity of fuel to be offered , ( iii ) usage per period limitations , ( iv ) tenor , ( v ) geography , and / or ( vi ) strike price . of course , in other embodiments , other combinations and / or additional factors and / or parameters may alternatively or additionally be provided . at block c 1 , the provider 206 structures a selection of fuel offerings , responsive to the distributor 204 request . the selection of fuel offerings may , in one embodiment , include associated premiums based on the parameters provided by the distributor 204 . in certain embodiments , the selection of fuel offerings may constitute a single fuel offering or a range of fuel offerings , as shown in table 1 below . depending on the embodiment , a fuel offering may be characterized its type ( e . g ., fuel type , such as regular unleaded gasoline , premium unleaded gasoline , diesel , bio - diesel , ethanol , hydrogen and / or the like ), strike price , tenor or term ( e . g ., 3 months , 6 months , 1 year , etc . ), calculated premium and / or the like . table i , illustrates , by way of non - limiting example , an exemplary range of fuel offerings which may be constructed by the provider 206 , responsive to a distributor 204 request . with continued reference to fig2 , at block c 2 , the range of fuel offerings , such as those shown in table 1 , are presented to the distributor 204 for his or her approval and / or selection . at block b 2 , the distributor 204 , may select one or more fuel offerings and make said offering ( s ) available to purchasers 202 . in one embodiment , it is contemplated that the fuel offering ( s ) may be made widely available over to a large population of potential purchasers over an electronic network , such as the internet . in the case where the distributor 204 does not select one or more fuel offerings , the process may return to block c 1 and the fuel offerings may be re - structured in an appropriate manner . at block b 3 , the distributor 204 may pay the provider 206 an upfront strike price plus premium and / or service markup , or otherwise paying only a premium and / or service markup . at block c 3 , the provider 206 may protect its fuel offering investment by employing hedging strategies , such as , for example , utilizing forward contracts , futures , wholesale fuel options and / or the like in appropriate combination ( s ). in some embodiments , the provider 206 may alternatively elect not to employ any hedging strategies . at block a 1 , a purchaser 202 may access the distributor 204 ( e . g ., via a web - site ) to purchase one or more fuel offerings being marketed by the distributor 204 . for example , with reference again to table i , a purchaser 202 may elect to purchase the first listed fuel offering ( see row 1 of table i ), at block a 2 , the purchaser 202 , in possession of the fuel offering shown above , may exercise the fuel offering to purchase fuel ( in this case , diesel fuel ) up to the stipulated quantity , during the indicated tenor , and at the indicated strike price . additional details of the transaction may be dependent upon the model being utilized by the distributor 204 ( e . g ., based on a national average price or a pump price ). for example , in some embodiments , when a purchaser 202 purchases fuel , the distributor 204 may pay the difference between the strike price ($ 2 . 50 ), and either the pump price at the point of purchase or a national average price on the date of purchase . in one embodiment , the fuel offering is priced to include the strike price plus the premium , so that upon exercising the fuel offering ( i . e ., buying gas ), the purchaser 202 pays out no money , and the fuel retailer is paid by the distributor 204 . as a further example , in accordance with one implementation of the pump price model , if the pump price is $ 3 . 00 and the fuel offering strike price is $ 2 . 50 , the purchaser 202 effectively pays $ 0 . 10 less than the pump price , considering a premium payment of $ 0 . 40 , which is advantageous to the purchaser 202 . at block b 4 , in response to the purchaser 202 purchasing fuel at block a 2 within the construct of the fuel offering , the distributor 204 pays the fuel retailer ( e . g ., gas station ) at the point of purchase the cost of the gasoline based on the pump price on the date of purchase . in an alternative embodiment wherein the purchaser has only paid a premium and not a strike price to the distributor up front , the distributor may only pay based on the difference between the pump price and the fuel offering strike price to the gas station . at block b 5 , the distributor collects feedback data on each fuel offering exercise and / or purchase , such as the one described at block a 2 and said data is provided to the provider 206 to enable refinement of future fuel offerings . the collected data may include the prices at which purchasers are exercising fuel offerings ( e . g ., purchasing fuel ) relative to the corresponding fuel offerings strike prices , the quantities involved and / or other indicia . at block c 4 , the provider pays the distributor the cost of the gasoline for which the distributor has paid the gas station . in an alternative embodiment , the provider may only pay the difference between the cost of the gasoline and the cost calculated based on the fuel offering strike price . fig3 a - b show aspects of financial structure model operation in particular embodiments of fuel offering generator operation . in fig3 a , a combined logic and data flow diagram is shown illustrating one implementation of the financial structure model . a pricing module 301 receives as inputs fuel market information 303 , historical analysis 305 , and offering parameters 310 . details surrounding the nature of these inputs , including examples thereof , and of pricing module operation , will be discussed in greater detail in the context of offering pricing below . the pricing module yields as output at least one offering price and / or price matrix 320 , that may be comprised of one or more offerings with associated strike price , premium , tenor , terms , service markup , restrictions , constraints , discounts , and / or the like . the pricing module may also yield as output at least one set of sensitivity data characterizing the sensitivity of price matrix elements to input parameters . for example , the sensitivity data may delineate , among other things , the sensitivity of the premium of a given offering or set of offerings to fuel market factors , such as retail gasoline spot prices . sensitivity may be represented , in one implementation , by the first derivative of the output variable ( e . g ., offering price , premium , strike price , etc .) with respect to an input variable ( e . g ., market factors , historical factors , offering parameters ). the provider determines at 330 whether the price matrix 320 is satisfactory based on a set of price matrix satisfaction criteria , which may include a consideration of the reasonableness of premium value and strike price combinations . price matrix satisfaction criteria may also be based in part on accumulated purchaser ( e . g ., consumer ) marketing research data 333 , such as data describing which offerings , premium and strike price combinations , etc . are most attractive to purchasers , which types of offerings are least likely to be exercised , and / or the like . if the price matrix 320 output by the pricing module 301 is not satisfactory based on the satisfaction criteria , then the offering parameters 310 may be adjusted in order to improve the alignment of the pricing matrix with the satisfaction criteria in the next iteration . if , on the other hand , the pricing matrix does meet a minimum standard of satisfaction , then the corresponding offerings are made available in a purchaser market , such as a consumer market 335 . purchasers may execute purchases of offerings 340 and , subsequently , exercise the offerings 345 to receive pay - outs consistent with offering terms . in one implementation , the provider itself may price offerings , make them available to a purchaser market , execute purchaser offering purchases , and honor purchaser offering exercises . in another implementation , the provider may price offerings and make them available to an intermediary distributor entity , who may provide them to a purchaser market and interface with purchasers for offer purchases and exercises . additional details surrounding provider - distributor - purchaser interactions in the context of offering exercise delays are discussed below . data related to offering executions and exercises ( e . g ., offering popularity , exercise rates , and / or the like ) may be monitored by the provider and incorporated into a purchaser marketing research data set that may be sampled in subsequent selection of offering parameters . for example , the provider may observe that all 3 - month tenor , regular octane gasoline offerings having a strike price of $ 2 . 90 / gallon and up sell considerably more poorly than other offerings regardless of the premium charged . subsequent offering generations may , consequently , exclude these offering parameters and / or terms altogether . offering exercise information may also be fed back into the pricing module through historical analysis variables that may alter the strike price and / or premium of particular offering rather than changing the presence or absence of offering parameters altogether . for example , the provider may observe that the profits derived from 12 - month tenor , regular octane gasoline offerings having a strike price of $ 2 . 00 / gallon are greater than expected because purchasers who exercise these particular offerings tend to behave sub - optimally . consequently , the system may incorporate that knowledge to charge a lower premium for these particular offerings that may attract more purchasers to these types of offerings and potentially increase the profits derived from them even more . data related to execution 340 and exercise 345 of offerings may also be incorporated , along with sensitivity data 325 , into provider hedging strategies and / or practices 350 . in an effort to offset , mitigate , and / or eliminate some amount of risk associated with the sale of offerings , the provider may elect to select , purchase , and / or manage a portfolio of hedging instruments . a provider devised hedging portfolio may be comprised of a variety of different types of holdings in various implementations that may include but are not limited to equities , debts , derivatives , synthetics , notes , stocks , preferred shares , bonds , debentures , options , futures , swaps , rights , warrants , commodities , currencies , long and / or short positions , etfs , and / or other assets or investment interests . in one implementation , a provider devised hedging portfolio may be comprised of forward contracts and / or futures of exchange or over - the - counter ( otc ) traded wholesale fuel options , gasoline options , and / or the like . sensitivity data 325 provides information describing the degree to which a particular input variable ( e . g ., a market parameter ) affects the strike price and / or premium of an offering . counteracting the risk associated with an offering may , therefore , be accomplished by seeking instruments whose sensitivity to input variables is similar in magnitude but opposite in direction to offering sensitivities . observed offering execution and exercise practices and / or trends of purchasers may further affect provider hedging strategies and / or practices . for example , an observation of sub - optimal exercise of offerings by purchasers may indicate to a provider that a smaller purchase of hedging instruments will suffice to offset the risk associated with the offerings . in the extreme case , wherein the offerings are never exercised under any circumstances , the provider would have no need for hedging instruments at all . further details surrounding hedging strategies and / or practices in the context of purchaser aggregation and scale are discussed below . fig3 b shows logic flow in an implementation of the financial structure model in one embodiment of fuel offering generator operation . a provider collects financial structure model inputs 360 , such as market factors , average and / or specific fuel prices , price and / or market factor geographic distributions , historical price data and / or market factors , offering parameters ( e . g ., strike price , premium , tenor , restrictions , discounts , incentives , and / or the like ), purchaser and / or consumer behavior considerations , hedging strategy considerations , and / or the like and stores them in a variables table at 365 . based at least in part on financial structure model inputs , the provider may determine a price matrix 370 . model inputs , outputs , and price matrix determination logic will be discussed in greater detail below . in one implementation , a price matrix may be comprised of a collection of offerings with varying terms , strike prices , premiums , incentives , restrictions , and / or the like . in one implementation , the provider and / or the distributor may further append a service markup to the strike price and / or premium to yield an offering price and / or collection of offering prices within a consumer price matrix . the provider may send 375 a price matrix , consumer price matrix , and / or some portion thereof 376 to purchasers for consideration and , for any purchasers who request to purchase offerings , the provider may subsequently receive notices of offering purchases 380 and execute offerings . these executed offerings may be sorted 383 and subsequently aggregated 385 into a plurality of similarity classes based on some desired criteria , such as purchaser location , selected offering parameters and / or terms , purchaser characteristics and / or demographics , purchaser behavior and / or history , and / or the like . a sensitivity and / or risk analysis 388 may be performed on the similarity classes in order to determine sensitivity of offering prices to various input parameters ( such as described above ) and risk characteristics that may be considered in a hedging strategy for subsequent hedging of provider risks and / or obligations . in addition , the provider may optionally perform correlation analysis 390 on similarity classes , similarity class sensitivities , and / or similarity class risks in order to determine which , if any , similarity classes exhibit similar sensitivity and / or risk characteristics and / or correlations . similarity classes with correlated sensitivity and / or risk behaviors may then be aggregated to simplify and / or expedite provider hedging strategies . the provider may subsequently implement hedging strategies and / or accumulate a hedging portfolio 395 . in one implementation , provider hedging strategies may be based in part on execution of purchaser offering purchases , purchaser offering exercises , and / or other purchaser behaviors ( e . g ., purchaser irrationality , and / or the like ) at different scales of purchaser granularity . in one implementation , provider hedging strategies may be based in part on individual purchaser offering purchases and / or exercises . for example , a large institutional purchaser ( e . g ., a trucking company ) may purchase a large enough offering and / or quantity of smaller offerings to motivate a provider to develop a hedge strategy based solely on the single purchaser purchase and / or behavior . in another implementation , provider hedging strategies may be based in part on aggregated purchaser offering purchases and / or exercises . for example , in this implementation , a purchaser &# 39 ; s offering purchase of a small quantity of gasoline may not affect the provider &# 39 ; s hedging strategy and / or portfolio . instead , the provider may enter a record of the offering purchase into a purchase repository for temporary storage and / or aggregation with other fuel offerings . the provider may then periodically analyze purchase repository contents in order to determine when there is an aggregation of purchaser offering purchases that is sufficiently large and / or significant to warrant consideration in the provider hedging strategy and / or modification of the provider devised hedging portfolio . aggregation of purchaser offering purchases may be made in a variety of different ways within various implementations . in one implementation , purchaser offering purchases may be aggregated based on time of purchase . in another implementation , purchaser offering purchases may be aggregated based on purchaser characteristics ( e . g ., demographics , location , purchaser behavior profile , and / or the like ). in another implementation , purchaser offering purchases may be aggregated based on the nature of purchasers ( e . g ., individual purchasers , small business purchasers , large business purchasers , government / institutional purchasers , and / or the like ). in another implementation , purchaser offering purchases may be aggregated based on the risk characteristics associated with purchasers and / or purchaser characteristics . in addition to storing execution of purchaser offering purchases for aggregation , a provider may additionally or alternatively store exercise of purchaser offerings for aggregation and subsequent consideration in hedging strategies . the provider may monitor and / or track purchaser offerings to determine if offerings are exercised 3100 . if a purchaser has exercised a purchased offering , then the provider may query the circumstances of the purchase exercise and pay - out the provider &# 39 ; s obligation under the terms of the offering in light of those circumstances 3105 . circumstances may include location , time , fuel price ( e . g ., the average price of gasoline in a region wherein the offering was exercised , a regional or national average fuel price , and / or the like ), status of purchaser owned offering and / or offering restrictions at the time of purchase ( e . g ., whether the purchaser has exceeded a monthly cap , whether the purchaser is in a restricted region , and / or the like ), and / or the like . in one implementation , the provider may determine the purchaser owned offering &# 39 ; s strike price and a reference fuel price at the time of offering exercise and , if the strike price is less than the reference fuel price , determine the difference between those prices , multiply that difference by the volume of gas on which the offering is being exercised , and implement any additional discounts , penalties , or restrictions in order to determine the payout amount . in one implementation , the reference fuel price is a regional average fuel price . in another implementation , the reference fuel price is a national average fuel price . the provider may also collect and / or analyze purchaser behavior characteristics 3110 . the provider may recollect and / or update financial structure model inputs at 3115 . the provider may also store collected and / or analyzed purchaser behavior characteristics in a purchaser table 3120 . in alternative implementations , a provider may interface with purchasers through an intermediary distributor entity . in such an implementation , the provider at 375 and / or 376 may send a pricing matrix or portion thereof to the distributor , who may then optionally select elements of the price matrix and / or add a service markup to create a consumer price matrix for subsequent presentation to purchasers . purchasers who wish to purchase offerings may request offerings from the distributor and offer payment based on the corresponding entries in the consumer price matrix . the distributor , in turn , may relay purchase requests to the provider 380 and / or purchase offerings from the provider , and relay those offerings back to the purchasers . when a purchaser exercises an offering 3100 , the distributor may pay - out to the purchaser to regain ownership of the offering and immediately submit an exercise notice to the provider to receive pay - out therefrom . alternatively , a distributor may pay - out obligations to purchasers when offerings are exercised by those purchasers , retake ownership of those offerings , and yet retain ownership until some later time at which an exercise notice is submitted to the provider . such a delay may allow the distributor to take advantage of subsequent market changes ( e . g ., increases in fuel prices ) that are foregone by suboptimal exercise of offerings by purchasers . such delay between purchaser and distributor offering exercise and / or suboptimal exercise by either purchaser or distributor may be considered by the provider in pricing matrix generation and / or hedging strategies . fig4 a - b show operation of financial structure pricing and price - pump model operation in respective embodiments of fuel offering generator operation . fig4 a shows processing flow for pricing of offerings in one embodiment of fuel offering generator operation . a collection of module inputs 401 may comprise current fuel market information 403 , historical fuel market information and / or analysis 405 , and observable 410 and non - observable 415 parameters derived therefrom . some examples of possible current fuel market information 403 may include current wholesale gasoline otc options market data , current wholesale gasoline otc forward market and futures market data , current retail gasoline spot prices , and / or the like . some examples of possible historical market information and / or analysis 405 may include historical wholesale gasoline otc options market data , historical wholesale gasoline otc forward market and futures market data , historical retail gasoline spot prices , historical wholesale gasoline spot prices , correlations between historical retail and wholesale gasoline prices , and / or the like . some examples of observable parameters 410 that may be derived from current fuel market information may include wholesale gasoline implied volatilities , wholesale gasoline forward curves , spread of retail over wholesale spot prices , and / or the like . some examples of non - observable parameters 415 that may be derived from historical fuel market information and / or analysis may include retail gasoline implied volatilities , wholesale gasoline mean reversion parameters , retail gasoline mean reversion parameters , retail gasoline forward curves , and / or the like . in one implementation , the pricing module may also admit as inputs a collection of purchaser historical data . purchaser historical data may be comprised of records of purchaser execution and / or exercise of offerings . in particular , the system may monitor purchaser execution and / or exercise of offerings with specific attention to particular purchaser behavior flags . in one implementation , a purchaser behavior flag may comprise consistent solicitation of and / or exercising of offerings at more expensive than average fuel retailers . in another implementation , a purchaser behavior flag may comprise consistent solicitation of and / or exercising of offering at cheaper than average fuel retailers . in another implementation , a purchaser behavior flag may comprise too optimal a pattern of offering exercising . in another implementation , a purchaser behavior flag may comprise too suboptimal a pattern of offering exercising . in another implementation , a purchaser behavior flag may comprise strong time dependence of purchaser exercising of offerings . if the number of observed purchaser behavior flags exceeds a threshold minimum value , a purchaser behavior history variable admitted as input to the pricing module may be adjusted so as to cause the pricing module to yield an adjusted pricing matrix intended to correct and / or direct future purchaser behavior . in addition to the aforementioned factors and variables , the pricing module may admit a collection of offering parameters that may specify offering terms presented to a purchaser . some examples of possible offering parameters may include strike price , premium , tenor , constraints , restrictions , incentives , discounts , fuel type , geographic location , and / or the like . in one implementation , a pricing module operator ( e . g ., provider ) may set values for some offering parameters and receive others as outputs from the pricing generator . for example , a particular desired strike price , tenor , set of restrictions , fuel type , and location may be input to the pricing module , and a premium received as an output from the module . alternatively , a particular desired premium , tenor , set of restrictions , fuel type , and location may be input to the pricing module , and a strike price received as an output from the module . the particular mode of operation , including selection of offering parameter inputs and outputs , may be varied within different implementations depending on the particular goals and / or requirements of particular applications of the system . values for a selected group of module inputs 401 may be fed into the pricing module 301 for processing . inputs are incorporated into an offering pricing model 425 such as , in one implementation , a commodity volatility model incorporated into a stochastic differential equation describing commodity value . an example of such a model is provided in u . s . pat . no . 7 , 065 , 475 entitled , “ modeling option price dynamics ,” filed on oct . 31 , 2000 , which is incorporated in its entirety herein by reference . u . s . pat . no . 7 , 980 , 960 entitled , “ system and method for providing a fuel purchase incentive ,” filed on mar . 28 , 2001 , and u . s . application ser . no . 09 / 853 , 196 entitled “ system and method for providing a fuel purchase incentive with the sale of a vehicle ,” filed may 11 , 2001 , are each incorporated in their entirety by reference . solving a stochastic differential equation to extract output offering parameters may be accomplished by a variety of techniques in different embodiments , such as but not limited to grid pricing , monte carlo simulation , analytic formulas , and / or the like . in one implementation , the xml for module inputs may take the following form : the pricing module 301 subsequently outputs sensitivity data 435 and price data 440 . price data 440 may , as discussed above , be comprised of different offering parameters depending on the requirements and consequent module inputs within a particular implementation . thus , the price data 440 output may include , but is not limited to , strike price , premium , tenor , restrictions , usage constraints , incentives , fuel type constraints , geographic constraints , and / or the like . sensitivity data 435 , as discussed above , describes the extent to which price data 440 may vary as module inputs 401 are varied . in one implementation , sensitivity data may be comprised of the first derivative of a price data variable with respect to one or more module input variables . in one implementation , the xml for module outputs may take the following form : the pricing module output described by the above xml includes a single strike price within the price_data / strike_price field . in an alternative implementation , a provider may determine price_data for a variety of module input values in order to yield an array of price_data with different corresponding offering parameters . such an array of price data with corresponding offering parameters may be incorporated into a pricing matrix . in one implementation , the xml for a three - offering pricing matrix may take the following form : fig4 b shows logic flow for determination of offering pricing within a pump - price model context in one embodiment of fuel offering generator operation . although geography is not necessarily central to the price structure itself , it is relevant , and greater detail about the may be found in fig1 - 11 . in this embodiment , the strike price associated with an offering is compared with the price charged by the particular fuel retailer at which an offering is exercised in assessing the extent of pay - out obliged to an exercising purchaser . for example , in a non - prepay embodiment wherein a purchaser has only paid a premium upfront , if a purchaser exercises an offering based on a strike price of $ 2 . 20 for a gallon of gasoline at a retailer that charges $ 2 . 40 / gallon , the purchaser may be refunded $ 0 . 20 / gallon by the provider , while the same offering exercised at a retailer charging $ 2 . 55 would yield $ 0 . 35 / gallon if exercised . in an alternative , prepay embodiment wherein a purchaser has paid both strike price and premium up front , the provider would directly pay the gas station the cost of the fuel based on either the $ 2 . 40 or $ 2 . 55 pump prices . due in part to the pump - specific sensitivity of this model , a number of additional restrictions and / or structural considerations , such as management of geographic price variations and undesirable purchaser behavior , may be implemented to facilitate desired generator operation and will be described in greater detail below . these factors may , in one implementation , be incorporated into determination of up - front pricing ( e . g ., premiums ) for fuel offerings . they may also , or in an alternative implementation , be considered as part of fuel offering redemption structure as discussed below and in fig1 - 12 and 14 - 21 . owing to the dependence of pump - price model payout on the price at the pump itself , considerations of variability between pump prices in different geographic regions must be incorporated . the generator develops a single - price zone ( spz ) map at 445 , wherein an spz is defined as a region and / or collection of retailers defined by a single , uniform pricing assignment . for example , a purchaser may exercise an offering with the same strike price at a given premium at all retailers belonging to the same spz . spz map determination is described in greater detail below in fig1 - 11 . the spz map defines spz boundaries and may guide the accumulation of historical pump price distribution data for a given spz 450 . historical purchaser bias data may also be accumulated for a given spz 455 . purchase bias data may , in one implementation , describe the extent to which purchasers tend to exercise offerings at retailers that are biased to one side or the other of the average of retailers within the spz . for example , a large purchaser bias may indicate that purchasers tend to exercise their offerings disproportionately often at expensive fuel retailers . the spz map and accumulated data may be employed to determine and / or collect further factors relevant to pricing within the pump - price model 460 . these factors may include the size of purchaser bias with an spz , volatility of that bias , convexity of that bias , and the existence of a no - arbitrage condition . convexity of bias in this context may , in one implementation , be construed to describe the extent to which there is a difference in the average pay - out amount between those offerings based on the difference between strike price and an average retailer pump price and those offerings based on the difference between a strike price and a pump price at which the offering is exercised . volatility of bias reflects the extent to which the distribution of prices within an spz may vary over time and the effect of such variation on deviations of purchaser behavior from average expectations . the no - arbitrage condition in this context may , in one implementation , be construed to describe the avoidance of a situation where a purchaser can buy an offering and immediately exercise to make riskless profit . these and other factors discussed may affect the cost of offerings and , consequently , be considered in either the up - front pricing ( e . g ., premium ) of offerings , or in the devising of incentives , restrictions , discounts , and penalties . a financial structure pricing determination is performed at 465 , similar to those described above in the context of the financial structure pricing model above , and the output premium and / or strike price is adjusted by an amount determined by the factors in 460 to yield a pump - price pricing 470 . an example of a premium adjustment made as part of the price - pump model may be to determine the average pump price within an spz , compute the total payout for an offering exercised at all retailers charging higher than that average , divide by the total number of retailers , and add this quantity ( the convexity of bias , in one implementation ) directly to the premium . another example of a premium adjustment made as part of the price - pump model may be to determine the standard deviation of average retailer pump prices within an spz over some period of time and add that deviation , or some fraction thereof , to the premium . further premium and / or strike price adjustments may be implemented within different embodiments of the fuel offering generator . based on the spz map developed in 445 , the generator may determine current and / or historical variability of basis ( i . e ., difference ) between spz premiums and / or strike prices for a given collection of spzs , such as a collection that is incorporated as part of a purchaser offering . based on that information , the generator may yield strike price and / or premium adjustments and / or a premium adjustment table , as described in greater detail in fig1 - 14 . the adjustment of premium price based on geographic considerations and / or the generation of a premium adjustment table may be relevant , in one implementation , to only those fuel offerings that cover fuel purchases made in multiple spzs . fig5 illustrates an aspect of purchase and fuel offering exercise for one embodiment of the fuel offering generator . prior to discussing process fig5 in detail , it is instructive to first review , in a broad sense , the purchaser &# 39 ; s perspective of fuel offering generator . the purchaser may be an entity who desires to purchase fuel offering to mitigate fuel costs over some period of time . in accordance with this goal , a number of fuel offerings may be made available for purchase by the distributor . a fuel offering may include specific details regarding the terms and conditions , as shown in the below example . the example fuel offering has a tenor of three months , during which the purchaser may exercise the fuel offering on up to 30 k gallons of diesel fuel at a strike price of $ 2 . 50 . the premium may , in some embodiments , represents the measure of risk associated with the fuel offering , i . e ., higher premiums may correlate to higher risk fuel offerings . by purchasing the fuel offering shown above , the purchaser mitigates the risk of fuel costing in excess of $ 2 . 90 ( strike + premium ) over the three month tenor . that is , by purchasing the fuel offering , the purchaser pays $ 0 . 40 for the ability or right to purchase fuel for $ 2 . 50 , up to the stipulated number of gallons ( e . g ., 30 k ). in some embodiments , an offer price of $ 2 . 90 ( strike + premium ) may represent the purchaser &# 39 ; s effective purchase price for any purchase made within the 3 month period for up to 30 k gallons of fuel if the cost of fuel over that three month period exceeds the offer price . as is apparent to the astute reader , exercising the fuel offering does not clearly provide economic benefit to the purchaser for prevailing pump prices and / or national average prices below $ 2 . 90 , though it may still be beneficial to the purchaser to exercise the offering between $ 2 . 50 and $ 2 . 90 because the premium is , at that point , a sunk cost . as shown in fig5 , the purchaser purchases a fuel offering with a particular strike price for certain fuel volume ( n ) 505 . at some point subsequent to the purchase of the fuel offering , the purchaser may decide to purchase x gallons of fuel 510 . in so doing , the purchaser may elect to exercise the offering on the fuel purchase of x gallons or not 515 , generally depending upon the pump price of fuel at the time of purchase . in the case where the cost of fuel is less than the strike price , it does not make economic sense for the purchaser to exercise the offering , for reasons described above , and in such a situation , the purchaser may simply pay the prevailing pump price 525 . alternatively , in the case where the cost of fuel is greater than the strike price , particularly where the cost of fuel is greater than the strike price + premium , it may make economic sense to exercise the fuel offering 520 , though the purchaser may not necessarily exercise the fuel offering ( e . g ., if the purchaser expects the cost of fuel to be even higher the next day ). in some embodiments , the fuel offering may be automatically exercised whenever the cost of fuel is greater than the strike , or alternatively , the strike + premium . in another embodiment , the fuel offering is not exercised automatically . if the purchaser decides to exercise the fuel offering 515 , the purchaser profile ( e . g ., a data file that includes information regard the purchaser &# 39 ; s fuel offering ( s )) or like information source regarding the fuel offering may be queried to determine the unused fuel volume ( r ) remaining for the fuel offering 520 . a determination is then made as to whether the remaining volume ( r ) is equal to or greater than purchase volume ( x ) 530 . if not , then the purchaser pays the prevailing pump rate 525 for the full purchase . in another embodiment the purchaser may be able to exercise the fuel offering for a partial amount of the full purchase ( i . e ., for the remaining volume ). otherwise , a determination is made regarding whether the prevailing pump price ( or other price , such as the national average price , as indicated by the implementation ) is greater than the strike price 540 . if so , the purchaser &# 39 ; s account is credited with the difference ( d ) between the strike price and the pump price , multiplied by the number of gallons ( x ) purchased 545 . otherwise , in the case where the prevailing pump price is determined to be less than the strike price 540 , the purchaser pays the prevailing pump price 550 . fig5 b provides an example strike vs . exercise graph for one embodiment of the fuel offering generator . the strike 552 is the strike price ( e . g ., $ 1 . 50 ) of the fuel offering and the exercise boundary 553 represents the price over which exercise of the fuel offering is approximately economically optimal over the tenor ( e . g ., 6 months ) of the offering . the exercise boundary 553 is initially the strike 552 plus an initial boundary and decreases to the strike at the end of the tenor of the offering . in some embodiments , the optimal initial boundary is found by maximizing the average pay - out across a range of initial boundaries , and the resulting exercise behavior ( e . g ., economically optimal exercise ) used to model purchaser behavior , including average pay - out . fig5 c and 5d provide further illustrate payout aspects for some embodiments . fig5 c provides a flow diagram for an embodiment in which the purchaser prepays the strike price ( e . g ., pays the premium plus the strike ) to the provider 561 and / or distributor at the time of purchasing the fuel offering . when the purchaser subsequently makes a fuel purchase 562 , there is a determination of whether the pump price is greater than the strike price 563 , and if not , the purchaser is charged the pump price 564 . if the pump price is greater than the strike price 563 ( or another threshold price as determined by the implementation ), in one embodiment , the purchaser &# 39 ; s fuel offering ( s ) is ( are ) exercised and purchaser &# 39 ; s profile is updated 565 , and the provider ( and / or distributor ) pays out the pump price 566 ( e . g ., to the fuel retailer ). in another embodiment , if the pump price is greater than the strike price 563 ( or like threshold price ), the purchaser may be notified and queried to determine if they wish to exercise their offering ( s ) 567 with the purchaser &# 39 ; s response 568 determining the next action ( 564 / 565 ). fig5 d provides a flow diagram for an embodiment in which the purchaser pays the premium to the provider 571 and / or distributor at the time of purchasing the fuel offering . when the purchaser subsequently makes a fuel purchase 572 , there is a determination of whether the pump price is greater than the strike price 573 , and if not , the purchaser is charged the pump price 574 . if the pump price is greater than the strike price 573 ( or another threshold price as determined by the implementation ), in one embodiment , the purchaser &# 39 ; s fuel offering ( s ) is ( are ) exercised and purchaser &# 39 ; s profile is updated 575 , the purchaser is charged the strike price 576 ( e . g ., pays the strike price to the fuel retailer ) and the provider ( and / or distributor ) pays out the difference between the strike and the pump price 577 ( e . g ., to the fuel retailer ). in another embodiment , if the pump price is greater than the strike price 573 ( or like threshold price ), the purchaser may be notified and queried to determine if they wish to exercise their offering ( s ) 578 and the purchaser &# 39 ; s response 579 decides the next action ( 574 / 575 ). fig6 illustrates an aspect of enforcing minimum usage of fuel offerings in an embodiment of the fuel offering generator . prior to discussing fig6 in detail , it is instructive to first briefly review the structure and purpose of imposing minimum fuel usage consumption . in some embodiments , a fuel offering sold to a purchaser may include a restriction directed to the manner in which the fuel offering is exercised over the specified tenor . as one example , consider an example fuel offering with the terms below . the exemplary terms of the illustrative fuel offering indicate a tenor of three months , during which the purchaser may purchase up to 30 k gallons of fuel at a strike price of $ 2 . 50 . to preclude the consumption of 30 k gallons all the end , or in disproportionate amounts over the three month tenor , it is contemplated that some embodiments may impose a minimum monthly usage requirement . in this manner , more predictable exercise of fuel offerings may be achieved . of course , in other embodiments , the restriction period may be of a longer or shorter duration ( e . g ., quarterly minimum usage , weekly minimum usage ) in accordance with the fuel offering tenor , and may be allocated in a variable fashion . referring now to fig6 , in one embodiment , enforcing a monthly minimum usage begins with a determination regarding whether the end of the current calendar date coincides with the end of the month 605 or some other stipulated period . the purchaser &# 39 ; s profile is queried to determine the monthly fixed volume ( f ), which represents the amount that the purchaser must use per month 610 . the purchaser &# 39 ; s profile is queried a second time to retrieve the total quantity of fuel already consumed by the purchaser for the current month , ( u ) 615 . a determination is then made regarding whether the total quantity of fuel already consumed in the current month ( u ) is greater than the fixed volume ( f ) 620 . if so , the process terminates because it is determined that the purchaser has already purchased in excess of the fixed volume ( f ) for the current month . otherwise , a calculation is performed to compute the difference ( d ) between the fixed volume ( f ) and the total quantity of fuel already consumed ( u ) 625 . a further evaluation is performed to determine the amount to be credited to the purchaser &# 39 ; s account for the unused portion . the further calculation determines an amount to be credited ( v ) corresponding to the value of ( d ) minus any fees ( e . g ., due to failure to meet fixed volume requirements ), multiplied by the strike price 630 . this amount ( v ) may then be credited back to the purchaser &# 39 ; s account 635 . for example , in one embodiment , if a purchaser purchases a fuel offering for a quantity of 500 gallons of gasoline over a tenor of 10 months , the fuel offering may specify a minimum monthly usage of 50 gallons , i . e ., f = 50 . in this exemplary case , if the purchaser uses less than 50 gallons in the first month ( e . g ., 20 gallons ), then the balance , 30 gallons ( i . e ., the unused portion ), is deducted from the purchaser &# 39 ; s total available volume , leaving 450 gallons at the start of the second month . in one embodiment , in the event of a prepay , the strike price for the deducted ( i . e ., unused ) gallons may be returned to the purchaser , while in another embodiment the prepayed strike for the deducted gallons are not returned to the purchaser . alternatively , if the purchaser uses an amount in excess of 50 in a particular month ( e . g ., 70 gallons ), then no action is required in that the purchaser has met his or her minimum usage requirement for the month . with reference now to fig7 , there is shown a process for enforcing periodic ( e . g ., monthly ) maximum fuel usage restrictions on fuel offerings . prior to discussing process in detail , it is instructive to first briefly review the structure and purpose of monthly fuel usage restrictions . in general , a fuel offering sold to a purchaser may include a restriction directed to the manner in which the fuel is consumed over the tenor of the offering . as one example , consider the following exemplary fuel offering — the exemplary illustrative offering has a tenor of three months , during which the purchaser may consume up to 30 k gallons of fuel with a strike price of $ 2 . 50 / gallon . to preclude the consumption of 30 k gallons all at once , or in grossly disproportionate amounts over the three month tenor , it is contemplated to impose a monthly cap ( i . e ., monthly maximum usage restriction ). in this manner , more predictable consumption and / or exercising of offerings may be achieved . of course , in other embodiments , the restriction period may be of a longer or shorter duration ( e . g ., quarterly cap , weekly cap ) in accordance with offering tenor . referring again to fig7 , the process for enforcing a monthly cap restriction begins with a purchaser 220 attempting to exercise an offering on a quantity of fuel ( e . g ., “ n ” gallons ) 701 . in response , the purchaser &# 39 ; s profile is queried to determine a cap ( e . g ., monthly cap ) amount specified as offering parameters within an offering owned by the purchaser . the purchaser &# 39 ; s profile may also be queried to retrieve a total quantity of fuel , “ m ”, previously consumed by the purchaser for the current month 703 . a determination is then made as to whether the sum of the fuel already consumed “ m ” by the purchaser in the current month plus the amount of fuel “ n ” on which the purchaser seeks to exercise his or her offering ( s ) is less than or equal to the monthly cap restriction 705 . if so , the purchaser is permitted to exercise on “ n ” gallons of fuel 707 . otherwise , a determination is made of the remaining amount of fuel that may be allocated to the purchaser to stay within the limitations of the imposed monthly cap 709 . the remaining amount which may be allocated is an amount “ b ”, less than the requested amount “ n ”, which may be determined by subtracting the amount of fuel already consumed in the month “ m ” from the monthly cap . the purchaser may , in one implementation , be issued a notice indicating that the purchaser &# 39 ; s remaining allowable monthly allocation is “ b ” gallons 711 . the purchaser may be offered the choice to proceed or not with the exercise of his or her offering on “ b ” gallons 713 . in the case where the purchaser elects not to proceed with exercising the offering , the purchaser may be charged the pump price 715 . otherwise , in the case where the purchaser elects to proceed , the purchaser is permitted to exercise his or her offering on “ b ” gallons 717 and the purchaser &# 39 ; s profile is updated to reflect the exercise of the offering 719 . in an alternative embodiment , the purchaser may be automatically charged the pump price if the exercise puts the purchaser over the cap for the period . in various embodiments , maximal usage restrictions may be implemented on a periodic , quasi - periodic , or non - periodic basis . for example , usage caps may be implemented and / or varied yearly , seasonally , monthly , weekly , daily , hourly , based on fiscal quarters , based on holiday travel patterns , based on expected high - traffic time periods , and / or the like . in one embodiment , the usage cap per period may be uniform over the tenor of the offerings owned by a purchaser , such as being set to the total quantity of fuel covered by the offerings divided by the number of periods covered by the offering tenor . in another embodiment , the usage cap per period may vary from period to period . with reference now to fig8 , there is shown a process for enforcing a cap payout restriction on fuel offerings in one embodiment . prior to discussing the process in detail , it is instructive to first briefly review the structure and purpose of cap payout restrictions . in general , a fuel offering sold to a purchaser may include a restriction directed to limiting the difference paid between the strike price and some reference price ( e . g ., pump price , national average price , spot price , and / or the like ) in order to minimize provider and / or distributor exposure and / or liability . as one example , consider the following exemplary fuel offering — the exemplary illustrative offering has a tenor of three months , during which the purchaser may consume up to 30 k gallons of fuel with a strike price of $ 2 . 50 / gallon . to preclude the purchaser from exercising the offering on purchases where the pump price or national average price is far in excess of the strike price , it is contemplated to impose a cap restriction on the payout . in other words , a payout cap may be established such that when the purchaser exercises his or her offering , the amount paid cannot exceed the payout cap . in this manner , a higher degree of certainty is guaranteed regarding payouts . more particularly , the payout is assured not to exceed the payout cap . for example , if a purchaser seeks to exercise an offering with a strike price of $ 2 . 50 / gallon on fuel with a reference price of $ 3 . 50 / gallon , and the payout cap is set to $ 0 . 50 / gallon , the purchaser will may only redeem $ 0 . 50 / gallon rather than the $ 1 . 00 / gallon he or she would receive in the absence of the payout cap . in an alternative embodiment , it is contemplated that the payout cap may be configured as a price cap , whereby any reference price exceeding the price cap on which a purchaser seeks to exercise an offering may be replaced by the price cap for the purpose of determining payout obligations . in a non - prepay example , if a purchaser seeks to exercise an offering with a strike price of $ 2 . 50 / gallon on fuel with a reference price of $ 3 . 50 / gallon , and the price cap is set to $ 3 . 00 / gallon , the purchaser will may only redeem $ 0 . 50 / gallon rather than the $ 1 . 00 / gallon he or she would receive in the absence of the price cap . in yet another embodiment , a payout and / or price cap may be expressed as some function of the premium and / or strike price ( e . g ., a percentage of the strike price ). referring now to fig8 in an implementation employing a payout cap , a provider and / or distributor may receive a notice of purchaser exercise of an offering on some quantity of fuel 805 . the purchaser &# 39 ; s profile may be queried to seek and / or extract a specified payout cap amount , “ k ” 810 . a determination is made 815 as to whether such a cap exists in the purchaser profile and , if not , then a basic payout amount is formulated 820 without consideration of a payout cap . otherwise , the generator queries a reference price corresponding to the offering being exercised . in one implementation , the generator may determine whether the offering is subject to a pump - price reference price ( e . g ., the price of the retailer at which the fuel is purchased ) or a financial structure reference price ( e . g ., a regional average price , a national average price , and / or the like ) 825 . in the former case , the reference price , z , may be set to the pump price 835 , and in the latter case , z may be set to a national average price . a strike price , s , corresponding to the offering being exercised may be queried from a purchaser profile 840 , and a determination made of the difference , d , between s and z 845 . if that difference does not exceed the payout cap , k , then a basic payout is prepared 855 without consideration of a payout cap . otherwise , the payout reimbursement to the purchaser &# 39 ; s account may be made based on the volume of fuel on which the offering is exercised subject to the payout restriction k . in an alternative embodiment wherein a price cap is specified rather than a payout cap , the comparison at 850 would be between the price cap and the reference price , z , and the payout amount at 860 would be based on the difference between the price cap and the strike price . in various embodiments , price and / or payout caps may be implemented on a periodic , quasi - periodic , or non - periodic basis . for example , price and / or payout caps may be implemented and / or varied yearly , seasonally , monthly , weekly , daily , hourly , based on fiscal quarters , based on holiday travel patterns , based on expected high - traffic time periods , and / or the like . in one embodiment , price and / or payout caps per period may vary from period to period . in another embodiment , multiple different price and / or payout caps may be specified for different circumstances , including different locations , regions , spzs , retailers , purchasers , distributors , providers , times , periods of time , and / or the like . fig9 illustrates one aspect of structural constraints in an embodiment of fuel offering generator . specifically , fig9 provides details for implementing and / or enforcing a structural constraint on the amount ( or percentage ) of gas volume that may be reimbursed upon exercising a fuel offering for a particular fuel purchase of a volume ( n ). in general , a fuel offering sold to a purchaser may include a restriction directed to the amount or percentage volume of a fuel purchase considered eligible for reimbursement upon exercising the fuel offering during its tenor . as one example , consider the following exemplary fuel offering terms — the exemplary illustrative fuel offering has a tenor of three months , during which the purchaser may exercise the fuel offering on up to 30 k gallons of fuel at a strike price of $ 2 . 50 . to discourage the purchaser from exercising the fuel offering at an fuel retailer that is relatively more expensive that other fuel retailers ( e . g ., a gas station that sells at $ 3 . 20 when most other stations sell at $ 3 . 00 ), some embodiments may impose a structural constraint that limits and / or specifies the amount ( or percentage ) of a fuel purchase on which a purchaser may exercise the fuel offering . as shown in fig9 , enforcing a structural constraint pertaining to the amount ( or percentage ) of a fuel purchase that may be reimbursed upon exercising a fuel offering for a specified purchase volume of gas ( n ) begins with a purchaser attempting to exercise a fuel offering on a purchase of ( n ) gallons of fuel 905 . in response to the purchaser &# 39 ; s attempt to exercise the offering on ( n ) gallons , the purchaser &# 39 ; s profile may be queried to retrieve associated structural constraint ( s ), defined herein as ( q ) 910 . in the embodiment of fig9 , this constraint defines a percentage multiplier to be applied to the purchase volume ( n ) to ascertain a reimbursable volume of fuel ( r ), as will be described . a determination is made regarding whether the query of the purchaser &# 39 ; s profile yields the structural constraint , that is , does the purchaser &# 39 ; s profile include the structural constraint , i . e ., variable ( q ). if not , the purchaser may exercise the offering on ( n ) gallons of fuel at the basic payout rate 920 . otherwise , a determination is made regarding the amount of fuel ( r ) that is considered to be reimbursable , in this case , a percentage of the total purchase amount ( n ) on which the purchaser desires to exercise the offering on 925 . for some embodiments , the determination may be a computation comprising multiplication of the ( n ) gallons of total fuel purchase by the constraint parameter ( q ) to yield a reimbursable volume of fuel ( r ). reimbursement is then made to the purchaser &# 39 ; s account based on the volume ( r ) 930 , i . e ., the fuel offering is exercised on ( r ) and not the total purchase ( n ). in some embodiments , the purchaser may be notified of the restricted reimbursement 935 . depending on the embodiment , structural constraints may be implemented on a fixed amount per purchase and / or be distributed over the tenor of a fuel offering in a periodic , quasi - periodic , or non - periodic manner . in one embodiment , the fuel offering generator may utilize single price zones ( spzs ) in determining a price matrix , strike price and / or premium of a fuel offering . spzs may define , for example , a geographic area and / or other grouping , such as certain station groups , station brands and / or the like , in which a fuel offering may be exercised ( i . e ., where the fuel offering purchaser may get his or her selected amount of fuel at the single , preset price ). in one embodiment , as shown in fig1 , the fuel offering generator may generate an spz map 1005 . in certain embodiments , a fuel offering may be restricted to only one spz . in another embodiment , the exercise of the fuel offering may be restricted to multiple , pre - selected spz ( s ), i . e ., the purchaser selects one or more spzs when purchasing the fuel offering , and can only exercise the fuel offering within the identified spz ( s ). in an alternative embodiment , the purchaser may be allowed to exercise the fuel offering outside of the single or multiple pre - selected spz ( s ), but doing so may be associated with an additional fee / penalty . based on the spz map ( and associated price matrix data ), the fuel offering generator may create pricing structures and / or strike adjustments for multi - spz purchasers 1010 . alternatively , or additionally , the fuel offering generator may determine fees / penalties for exercising fuel offerings outside of the pre - selected spz ( s ) 1011 . in one embodiment , the pricing structures , strike adjustments and / or fees / penalties are fixed at purchase ( e . g ., a purchaser buys a fuel offering for spz1 and locks in an adjustment of $ 0 . 25 per gallon for spz2 for purchases , if any , in spz2 ). in another embodiment , the pricing structures , strike adjustments and / or fees / penalties may be floating and / or variable until the time of exercise . the fuel offering generator may also manage purchasers &# 39 ; utilization of spzs 1015 , including managing purchasers &# 39 ; pricing structures , strike adjustments and / or fees / penalties . fig1 provides additional detail regarding spz mapping and management for an embodiment of the fuel offering generator . upon receiving a request to determine spzs 1101 , the fuel offering generator may determine if the spzs are to be set to existing geographic boundaries 1105 . if the spzs are to be set to existing geographic boundaries 1105 , the fuel offering generator determines what scale ( e . g ., city , county , metropolitan area , state and / or region ) for setting the boundaries is appropriate 1110 . in one embodiment , the size of the spz may be particularly relevant in pricing associated fuel offerings , for example , the fuel offering for a large spz may be relatively expensive due to adverse selection and / or moral hazard issues due to a larger distribution and / or geographic area . similarly , in one embodiment , the fuel offering generator may determine spzs to minimize excluding or “ shutting out ” potential purchasers , for example , purchasers in upstate new york may prefer a fuel offering in which geographic spz determination is based on county , rather than state . the fuel offering generator may also account for other issues in determining spzs , such as the smaller the spz , the more restrictive the fuel offering and / or the more complicated the adjustments needed to use the fuel offering products across spzs . based on such information , the fuel offering generator may then set the boundaries of the spzs to the appropriate existing geographic boundaries 1115 . while some embodiments may set spzs according to one scale , other embodiments may combine scales in constructing spzs ( e . g ., one spz &# 39 ; s boundary may be set to a city , while another spz &# 39 ; s boundary is set to a state ). the fuel offering generator may then determine the price matrix for each spz 1145 and store the price matrices in a spz table 1150 . if the spzs are not to be set to existing geographic boundaries 1105 , the fuel offering generator collects 1120 and stores 1125 a geographic distribution of pricing variables . the fuel offering generator may then perform a similarity analysis on the geographically distributed pricing variables 1130 and , as described previously , determine the scale or granularity with which the spz divisions will be set 1135 . the fuel offering generator may then assign spzs according to the similarity analysis and / or determined granularity 1140 . in a further embodiment , the assigned geographic boundaries may include , but are not limited to , existing geographic boundaries . the fuel offering generator then determines the price matrix for each spz 1145 and stores the price matrices in an spz table 1150 . fig1 provides additional detail regarding the spz pricing aspect of an embodiment of fuel offering generator . a purchaser interacts with the fuel offering generator and specifies desired terms for a fuel offering 1205 . the purchaser then specifies one or more spzs in which they want the ability to exercise the fuel offering 1210 . the fuel offering generator then determines is the purchaser has specified multiple spzs 1215 , and if not , serves the fuel offering pricing based for the desired terms and selected spz 1220 . in one embodiment , if the purchaser has specified multiple spzs 1215 , the fuel offering generator identifies the most expensive spz of the multiple spzs based on the desired terms 1225 and derives an adjustment table ( e . g ., a strike adjustment table ) for the other specified spzs 1230 . in other embodiments , the fuel offering generator may derive an adjustment table for a purchaser &# 39 ; s primary spz ( e . g ., the purchaser &# 39 ; s default location , most traveled location , and / or the like ), with credits for exercising fuel offerings in relatively cheaper spzs and debits or penalties for exercising in relatively more expensive spzs . the fuel offering generator may then serve the fuel offering pricing based on the most expensive selected spz and the derived adjustment table for the purchaser &# 39 ; s desired terms 1235 . moving momentarily back to the topic of restrictions and constraints , in some embodiments , the fuel offering generator may provide fuel offerings that in which there is a withdrawal expiry , i . e ., a certain amount or percentage of the initial amount ( e . g ., initial volume amount of the fuel offering ) that must be exercised before a specified time or else be subject to expiration . for example , the specifications of a certain fuel offering may include a particular strike price , a total volume of 1200 gallons , a term of one year , and requirement that the purchaser must exercise at least 8 . 33 % ( i . e ., purchase at least 100 gallons ) each month or else lose the difference . in one embodiment , the withdrawal expiry is set uniformly , for example , if the term of the fuel offering is one year , and the length of a sub - period is one month , 8 . 33 % of the initial total of the fuel offering must be exercised by the end of each month or be subject to expiration , while in another embodiment , the withdrawal expiry could be non - uniform . fig1 a illustrates the available exercise volume per month for a fuel offering with a term of one year , an initial exercisable volume of 1200 gallons , and a withdrawal expiry of 8 . 33 % ( 100 gallons ) per month . as can be seen in the figure , the purchaser may exercise any or all of the 1200 gallons in the first month , but only a maximum of 100 gallons by the last month . in one implementation , the required exercise could be based on a cumulative amount , for example , in the situation described above , if a purchaser exercised 20 % in the first month and only 1 % in the second month , no part of the fuel offering would be subject to expiration ( i . e ., 20 %+ 1 % is greater than 8 . 33 %+ 8 . 33 %). alternatively , in another implementation , the withdrawal expiry could be periodic , so that either a certain percentage of the initial or remaining amount must be exercised each period or be subject to expiration . in one embodiment , the purchaser may exercise the entire remaining ( i . e ., non - expired ) amount of the fuel offering , while in another embodiment , the fuel offering may also be subject to usage caps . fig1 b provides additional detail for the withdrawal expiry aspect of one embodiment of the fuel offering generator . after generation of the fuel offering , the fuel offering generator checks whether it is the end of the specified sub - period 1305 , and if it is not , cycles / waits 1335 and re - checks 1305 . if it is the end of the specified sub - period 1305 , the fuel offering generator queries the purchaser profile for the specified sub - period expiry volume 1310 and the purchaser &# 39 ; s sub - period exercise volume 1315 . if the purchaser &# 39 ; s sub - period exercise volume is greater than or equal to the specified sub - period expiry volume 1320 , then no part of the purchaser &# 39 ; s fuel offering expires and the fuel offering generator waits for the end of the next period 1335 . however , if the purchaser &# 39 ; s sub - period exercise volume is less the specified sub - period expiry volume 1320 , then the fuel offering generator determines the difference between the sub - period expiry volume and the sub - period exercise volume 1325 and expires that amount from the purchaser &# 39 ; s fuel offering , updates the purchaser &# 39 ; s profile 1330 , and waits for the end of the next sub - period 1335 . in one embodiment , if the purchaser prepaid the strike price , the strike price for the expired amount may be returned ( but not the premium ). alternatively , some embodiments do not return the prepaid strike price . returning to the topic of geography , fig1 provides an overview of one aspect of the multi - spz fuel offering exercise in an embodiment of the fuel offering generator . the fuel offering generator receives purchaser exercise information for a fuel offering 1405 , for example , in one implementation , via an electronic credit transaction . the fuel offering generator may then determine or extract from the exercise information the location information ( e . g ., address of the gas station ) where the purchaser exercised the fuel offering 1410 , and matches the location to the corresponding spz 1415 . if the spz corresponding to the exercise location information is also the most expensive spz of the purchaser &# 39 ; s specified spzs 1420 , then the transaction is completed 1425 . if the spz is not the most expensive spz of the purchaser &# 39 ; s specified spzs 1420 , the fuel offering generator extracts the appropriate discount from the adjustment table 1430 and credits the purchaser &# 39 ; s account 1435 . in a further embodiment , an adjustment table may also include penalties that could be charged to a purchaser for exercising the fuel offering outside of a pre - selected spz ( if allowed by the fuel offering generator ). in one embodiment , the adjustment table is a strike adjustment table indicating the refund or rebate the purchaser would receive if they exercised the fuel offering in one of the selected spzs which was not the most expensive spz . for example , if a purchaser selects a fuel offering with two spzs , manhattan and pittsburgh , and the manhattan spz is the most expensive , the purchaser would pay for fuel offering based on the manhattan indicated price . however , if the strike adjustment table indicated an adjustment of $ 0 . 10 for pittsburgh , and the purchaser exercised the fuel offering in pittsburgh , the purchaser may receive a corresponding credit or rebate for exercising the fuel offering in the less expensive spz . fig1 through 18 illustrate the process flow for one aspect of purchaser behavior management in an embodiment of the fuel offering generator . as shown in fig1 , the fuel offering generator may collect relative pump price usage data for a purchaser 1505 ( for example , the pump price at which the purchaser exercises one or more fuel offerings relative to the pump price at which other purchasers with like characteristics , such as location and / or similar fuel offerings , exercise fuel offerings ). alternatively , or additionally , other purchaser behavior data such as the relative time - from - purchase - to - exercise of fuel offerings , suboptimal exercise traits ( e . g ., whether the purchaser typically exercises the fuel offering suboptimally , and if so , if said exercise is pre - optimal and / or post - optimal ), and / or the like , as well as purchaser characteristics ( e . g ., demographic information ) may also be collected . depending on the implementation , the above data may be collected periodically and / or continuously . in some embodiments , the collected data for multiple purchasers may be amassed and marketing and behavior analyses performed to identify relevant trends and characteristics of purchasers , including data regarding adverse selection ( e . g ., within a particular spz , if there is more interest in fuel offerings among purchaser &# 39 ; s who typically pay higher prices ) and / or moral hazard information ( e . g ., if purchaser &# 39 ; s start frequenting more expensive fuel retailers after purchase of fuel offerings ). the fuel offering generator may utilize the collected data to characterize a purchaser , and the characterization may be based on the purchaser &# 39 ; s current information and / or aggregate information . if the characterization is based on aggregate information 1510 , the fuel offering generator determines an aggregate purchaser behavior profile 1515 , while if the characterization is based on current purchaser information 1510 , the fuel offering generator determines a current purchaser behavior profile 1520 . based on the purchaser behavior profile , the purchaser may be grouped , rated and / or otherwise identified , where such identification is used in optimizing subsequent interactions with the purchaser . for example , as shown in the figure , in one embodiment , the purchaser may be identified as preferred , undesirable , or indifferent 1525 . in one implementation , the grouping may reflect the relative value the purchaser represents ( e . g ., profitable , unprofitable , or break - even , respectively ). the identification may be stored in the purchasers profile 1530 , and in some embodiments , the purchaser may be notified of their associated status and / or associated incentives or penalties ( as described below in fig1 , 17 and 18 ). as shown in fig1 , in one embodiment , if the purchaser is preferred , the fuel offering generator may determine if the purchaser &# 39 ; s length of stay ( i . e ., the time the purchaser has had a relationship with the fuel offering generator and / or associated entities ) is greater than a certain threshold 1640 , the fuel offering generator may associate a length of stay incentive package ( such as discounts , rebates , and / or the like ) with the purchaser &# 39 ; s account and / or profile 1645 . if the purchaser &# 39 ; s length of stay is not greater than a certain threshold 1640 , the fuel offering generator may associate another style of incentive package with the purchaser &# 39 ; s account and / or profile 1650 . depending on the purchaser characteristics , rewards or incentives may be directed to retain purchasers , encourage increased use and / or acquisition of fuel offerings , and / or otherwise encourage or modify future purchaser behavior . similarly , fig1 shows purchaser incentive structures 1780 , 1785 , 1790 related to those shown in fig1 ( 1640 , 1645 , 1650 , respectively ), and further illustrates an embodiment in which the fuel offering generator determines if the purchaser is in a high variance zone 1770 ( e . g ., purchaser could be exercising fuel offerings at relatively expensive gas stations , but is not doing so as indicated by their preferred status ), and if so , associating a supplemental bonus incentive package with the purchaser &# 39 ; s account and / or profile 1775 ( e . g ., a package that reinforces / rewards positive purchaser behavior ). alternatively , if the purchaser is undesirable 1525 , in one embodiment , as shown in fig1 , the fuel offering generator may determine if the purchaser represents aggregate undesirability 1855 ( e . g ., the purchaser has been undesirable for a significant portion of the relationship between the purchaser with the fuel offering generator and / or associated entities ), and if so , may terminate the purchaser &# 39 ; s account and / or not provide the purchaser with additional fuel offerings . if the fuel offering generator determines the purchaser does not have aggregate undesirability 1855 , a penalty package ( or an incentive package that directs the purchaser towards preferred behaviors ) may be associated with the purchaser &# 39 ; s profile and / or account 1865 . fig1 illustrates the process flow for one aspect of purchaser behavior management in one embodiment of the fuel offering generator . the fuel offering generator may sample an spz pump price distribution 1905 in order to extract therefrom one or more statistical quantities characterizing fuel retailers within the spz . in one implementation , the generator samples pump prices across all retailers within an spz , while in another implementation the generator samples pump prices from some representative subset of fuel retailers within the spz . in still another embodiment , the generator may sample pump prices across a subset of retailers in the spz that excludes one or more non - participating fuel retailers from consideration . the generator may determine a measure of pump price spread ( σ ) 1910 , such as a standard deviation , variance , and / or the like . a determination is made 1915 as to whether this pump price spread measure exceeds a pre - established threshold , and if not , then the process of fig1 completes with no further action . otherwise , if the pump price spread measure exceeds the threshold 1915 , then fuel retailers in the spz may be segmented into a plurality of price groups based on the relation of their pump prices to the average pump price 1920 . for example , fuel retailers may be segmented and / or grouped based on the number of standard deviations away from the mean pump price that their pump prices fall . in one implementation , a fuel retailer &# 39 ; s current pump price is considered , while in another implementation the fuel retailer &# 39 ; s pump price averaged over some period of time is considered . in some embodiments , the segmentation information may be used by the fuel offering generator as an input in determining a price matrix and / or in constructing an appropriate hedging strategy . based on this segmentation , the generator may incentivize or penalize purchaser solicitation of particular fuel retailers 1925 . in some embodiments , incentives and / or penalties may be provided and / or assessed immediately ( i . e ., communicated to purchaser &# 39 ; s to directly influence behavior ), while in a further embodiment , such incentives and / or penalties may take the form of modified premiums , price adjustments and / or restrictions associated with subsequent fuel offerings . fig2 illustrates an aspect of fuel retailer incentivizing for some embodiments of the fuel offering generator . the fuel offering generator samples spz pump price distribution 2005 for one or more statistical quantities characterizing fuel retailers within the spz , in one embodiment in the process as described in fig1 . the fuel offering generator may determine a measure of pump price spread ( σ ) 2010 , such as a standard deviation , variance , and / or the like , and a determination is made 2015 as to whether this pump price spread measure exceeds a pre - established threshold , and if not , then the process of fig2 completes with no further action . otherwise , if the pump price spread measure exceeds the threshold 2015 , the fuel offering generator segments fuel retailers in the spz into a plurality of price groups based on the relation of their pump prices to the average pump price 2020 , similar to fig1 above . the fuel offering generator then determines the fuel offering utilization within and / or across the price groups 2025 and identifies if , for a particular price group and / or specific fuel retailer ( s ) within the price group , there is minimum utilization by purchasers 2030 ( i . e ., most purchasers are not exercising their fuel offering ( s ) s at the fuel retailers within the price group ). in some embodiments , information regarding fuel offering utilization within and / or across the price groups may be used by the fuel offering generator as an input in determining a price matrix and / or in constructing an appropriate hedging strategy . if there is not minimum utilization 2030 , in particular , if there is not minimum utilization of the more expensive fuel retailers by purchasers , the fuel offering generator does not continue the process of fig2 , and in a further embodiment , the fuel offering generator may reassess associated pricing , incentives , penalties , premiums , price adjustments and / or restrictions , for example , as described in fig1 . if there is minimum utilization of a price group and / or particular fuel retailer ( s ) by purchasers 2030 , as shown in fig2 , the fuel offering generator may determine the group mobility premium 2135 . in one embodiment , the group mobility premium represents the value that inclusion in another price group ( and the associated increase in purchaser solicitation ) represents to the fuel retailer ( s ), while in another embodiment the group mobility premium represents the cost of allowing and / or not disincentivizing purchaser solicitation of the fuel retailer ( s ). in yet another embodiment , the group mobility premium represents the value that purchasers place on having access to the particular price group and / or fuel retailer ( s ). the group mobility premium may , in some embodiments , by utilized by the fuel offering generator as an input in determining a price matrix and / or in constructing an appropriate hedging strategy . in one embodiment , the fuel offering generator and / or associated entities may utilize the group mobility premium in offering or negotiating group mobility ( e . g ., the removal of restrictions and / or penalties to allow fuel retailers access to purchasers ) with one or more fuel retailers . this may be particular attractive to fuel retailers with relatively high pump prices ( such as premium gas stations or conveniently located retailers ) in that it allows for segmentation of customers and / or de facto price discrimination . for example , in one embodiment , a gas station could continue to charge a relatively high pump price to typical customers , while also gaining access to the solicitation of purchasers . if the fuel retailer accepts the offer and associated group mobility premium 2145 , the fuel offering generator adjusts the fuel retailer &# 39 ; s position within the price groups 2150 . in one embodiment the group mobility premium could be paid by the fuel retailer to the fuel offering generator ( and / or associated entities ) as a one time and / or periodic fee . in another embodiment , the group mobility premium could consist of and / or further include a revenue and / or risk sharing agreement , with pricing adjustment and / or payments from the fuel retailer to the fuel offering generator ( and / or associated entities ) and / or vice versa . in yet another embodiment , said pricing adjustments and / or payments could be made from the fuel retailer and / or fuel offering generator ( and / or associated entities ) to the purchaser , as necessary . in some embodiments , the group mobility premium and associated arrangements may be used by the fuel offering generator as an input in determining a price matrix and / or in constructing an appropriate hedging strategy .

controller as a subcarrier transport mechanism for interaction , such as , but not limited to : multicast , tcp / ip , udp , unicast , and / or the like . an information server component 2216 is a stored program component that is executed by a cpu . the information server may be a conventional internet information server such as , but not limited to apache software foundation &# 39 ; s apache ,

information server may support secure communications protocols such as , but not limited to , file transfer protocol ( ftp ); hypertext transfer protocol ( http ); secure hypertext transfer protocol ( https ), secure socket layer ( ssl ), and / or the like . the information server provides results in the form of web pages to web browsers , and allows for the manipulated generation of the web pages through interaction with other program components . after a domain name system ( dns ) resolution portion of an http request is resolved to a particular information server , the information server resolves requests for information at specified locations on the fuel offering generator system controller based on the remainder of the http request . for example , a request such as http :// 123 . 124 . 125 . 126 / myinformation . html might have the ip portion of the request “ 123 . 124 . 125 . 126 ” resolved by a dns server to an information server at that ip address ; that information server might in turn further parse the http request for the “/ myinformation . html ” portion of the request and resolve it to a location in memory containing the information “ myinformation . html .”
