Abstract: The expanding coupler for a mower and lawn vacuum may pull a suction hose adjacent to a deck adapter outlet. A plurality of hose springs may allow the suction hose to separate from the deck adapter outlet when the suction hose is pulled. The shroud may direct clippings from the deck adapter outlet to the suction hose when the suction hose is separated from the deck adapter outlet. As a non-limiting example, the suction hose may couple a deck adapter of a lawn vacuum to a suction hose adapter of the lawn vacuum. The suction hose may be pulled when the riding lawn mower makes a turn in a direction that is opposite the side that the suction hose is on. Fasteners may prevent the suction hose from separating from the hose adapter.

Abstract: A method for conducting an exchange auction includes a computer receiving financial positions data defining long and short positions associated with a first financial instrument. The method further includes matching, by the computer, one of the short positions and one of the long positions and generating a first proposed trade including the matched positions. The method further includes generating, by the computer, a second proposed trade including a short position and long position associated with second financial instrument, such that a net notion of the first proposed is equal to a notional of the second propose trade. The method further includes executing the first and second proposed trades.

Abstract: A method for trading financial instruments includes listing, by an electronic financial exchange, financial instruments that specify which version of a serialized index the financial instrument tracks; receiving, by the electronic financial exchange, an electronic indication to buy or sell the financial instrument; executing, by the electronic financial exchange, a trade involving the financial instrument; and settling the financial instrument according to the version of the serialized index specified by the financial instrument.

Abstract: An electronic netting system. The system may include: (a) a plurality of individual, segregated counterparties for providing bilateral trades, (b) a multi-lateral transaction hub, and (c) a trading system in communication with the transaction hub. The multi-lateral transaction hub may be for (i) providing an aggregation of trades between the counterparties, (ii) providing for multi-lateral netting of selected and authorized bilateral trades, and (iii) apportioning the accumulated trade values among the counterparties according to pre-determined netting parameters including a weighted distribution selectable by at least one of the counterparties. The transaction hub may include: (i) a trade processing system and (ii) a netting system in communication with the trade processing system for providing for the optimized, multi-lateral netting of selected and authorized bilateral trades and apportioning the accumulated trade values among the counterparties.

Abstract: A netting method replaces a set of trades between a pair of counterparties. The method includes a selection of multiple trades having equivalent terms and a determination of the net notional and net coupon. Replacement trades are created, the combined net notional and combined net coupon of which respectively equal the net notional and net coupon of the multiple trades being replaced. A position matching method is implemented for portfolio compression. An implied spread is calculated for each position of a portfolio. Positions with an implied spread outside of desired bounds are corrected. A buyer and a seller are selected, the buyer having the position with the highest implied spread value of all net long and the seller of all net short protection positions. The created trade has a notional equal to the smaller of the net default exposure and a spread of the implied spread with a smaller position.
