摘要:
A system and method is disclosed for determining performance bonds related to fixed payoff products, i.e. contracts which payoff a fixed amount based on the outcome of an underlying event regardless of the particular value of the underlying event. The worst outcome of the overall portfolio, which may contain more than one instrument, is calculated. This permits the portfolio to have both long and short positions on the same underlying event and offsets, e.g. long (bought but not closed out) and short (sold but not closed out) positions, among instruments in the portfolio are factored in. A universe of outcomes is constructed including single events with single outcomes, and the probability thereof, an single events with multiple outcomes, each with a probability thereof. This universe is implemented in a matrix probabilities on different outcomes, also referred to as “strikes.” Each strike/outcome then has an associated price and probability, typically factored together as single value reflective of both. Events with low probability will have low values, resulting in a lower margin requirement, as will be explained below. The margin requirement/performance bond is then set equal to the amount of the maximum loss that the portfolio can sustain for any possible outcome of the underlying event, adjusted for the probability of the outcome.

A system and method for risk analysis of a portfolio of derivative products is disclosed which is conducted based on a set of flexible rules. The system and method allow creating predefined sets of products for the purpose of future risk offsets. If a futures trade as a subset of that set of products that met a threshold level, then the subset is assigned the offset value (or a pro rata or other portion of the offset value) of the predefined set. For example, assume that the predefined set consists of one S&P 500 futures, one NASDAQ futures, one S&P Midcap 400 futures and one Russell 1000 futures and the threshold is three. If the futures trader holds any three of those four futures, the three futures can be grouped, assigned an offset value, and this group can be used as one asset for purpose of further risk offsets.

A hybrid cross-margining system is disclosed. The disclosed provides for both joint accounts, maintained by multiple exchanges, as well as non-joint accounts, whereby the system recognizes both intra-account offsets within the joint account and inter-exchange offsets between the joint account and accounts maintained by another exchange to minimize the margin requirement of the associated market participant with respect to the positions reflected in these accounts.

A risk management system and method is disclosed which utilizes a flexible and configurable set of spreading techniques which may be incorporated into existing risk management software to enhance functionality, flexibility and accuracy. In the disclosed embodiments, multiple different types of spreading are combined to allow for a more accurate assessment of risk. In one exemplary embodiment, a subset of the derivative products held by a futures trader are first analyzed by the scanning based spreading methodology. Typically, futures products in the same class of products (e.g. equity futures or agricultural futures) would be analyzed together by the scanning based spreading methodology. Then an average delta would be calculated for that subset. Using that delta, that subset would then be analyzed in relation to the remaining derivative products(not in the subset) using a delta based spreading methodology. The delta for the subset could be computed in a variety of ways including scaling the deltas for each product, tying the delta to a fixed time period or other methods.

A system and method for using asymmetrical offsets for products in a risk management analysis system are disclosed. Conventional systems assign symmetrical offsets for products, that is, if two products have an 80% correlation they each would be assigned an offset of 80% with respect to each other. However, it is desirable to allow for asymmetrical offsets. In the disclosed system and method, when two products have a correlation of 80%, one may be assigned an offset of 75% and the other may be assigned an offset of 80%. There are many reasons to vary the offset between the products. The varying offset may reflect an asymmetry in the risk in one of the products, such as being traded in an illiquid market or in a less desirable venue. The varying offset may correct for an imbalance in spread credits due to special charges from intra spreading.

A system and method for analyzing correlation between the assets given by the trader for collateral and that trader's open positions is disclosed. Thus, if the collateral is correlated to the trader's open positions, then some offset can be given. If there is no correlation than the collateral is valued in the conventional way. For example, if a trader provides t-bills as collateral for an account that has open positions (e.g. short futures) in T-bills, than that trader's account can be credited with some offset since the value of T-bills and T-bill futures are highly correlated.

A system and method for factoring in a trader's trading activity into the margin requirements is disclosed. In the securities arena, day traders are assessed different margins than non-day-traders, however, the specific profile of the trader is analyzed (that is, the same rule applies to all day traders).

A graphic user interface is disclosed that combines a traditional trading, bookkeeping system or clearing system window with a detailed margin and/or collateral asset calculation analysis window on a single screen. The disclosed GUI provides the flexibility to analyze any combination of products or instrument classes such as single stock futures, futures (of all types), options (of all types), forward contracts, security options, securities and cash-based assets. Conventional systems merely block entry of orders beyond a predetermined credit limit or display clearing/bookkeeping information on all types of portfolio or accounts. The disclosed GUI, in an automated real-time or manual execution control basis, provide the user useful information (all types of numerical and/or graphical display) concerning which products contribute to and how much each product position contribute to the margin limits on, for example, multiple levels; all types of product level, product period (duration) level, account level and clearing level, etc. In one embodiment, the margin window may include a “what if” Scenario Panel and an “Actuals” Margin Analysis Panel. This Scenario Panel allows the user to experiment with “what-if” scenarios in real time or on an as-needed basis. This allows the user to better assess the changes an “actual” position(s) or “what-if” position(s) may have on the margin requirements on all account level types. Further, the actual panel displays the account's actual positions and the associated contributions each position has to that account's margin requirements.

A high-speed Galois Counter Mode-Advanced Encryption Standard (GCM-AES) block cipher apparatus and method is provided. The apparatus can operate at a low clock frequency of 125 MHz and provide a 2 Gbps link encryption function in an Optical Line Termination (OLT) and an Optical Network Unit (ONU) of an Ethernet Passive Optical Network (EPON). 11-round block cipher of 128-bit input data is implemented using an 8-round Counter-AES (CTR-AES) block cipher module and a 3-round CTR-AES block cipher module, so that it is possible to provide a 1 Gbps link security function for an input frequency of 62.5 MHz and a 2 Gbps link security function for an input frequency of 125 MHz.
