Abstract: Various embodiments are directed to a system and method for matching providers (e.g., lenders) and receivers (e.g., borrowers or purchasers) of a good (e.g., a tangible product or loan funds). The provider may specify one or more parameters of a commitment to provide the good, such as quantity and delivery specifications. Before a receiver accepts the commitment, the provider may provide a portion of the total commitment (e.g., a margin amount of a loan or a percentage of a quantity of a tangible product). A one-time or continuing commitment fee may be paid to the lender for providing the loan commitment. The commitment fee may be based on the loan commitment amount and/or the margin amount. When a borrower accepts the terms of the loan commitment, the lender may fund the remaining balance of the loan principal amount. If the lender fails to fund the remaining balance, the lender may forfeit the margin amount.

Abstract: Some embodiments may relate to managing the risk of losses over a variety of risk venues. For example, a central system may monitor trading losses and profits by an entity over a plurality of exchanges. When losses exceed profits by some threshold amount, trading at the exchanges may be halted. Other example methods and apparatus are described.

Abstract: A height adjustable light fixture support includes a first U-shaped bracket with a crosspiece and first and second depending legs. The U-shaped bracket will be secured in a ceiling box. A slidable, height adjustable second U-shaped bracket supports a light and includes separated first and second plates, each of which is shaped to define a respective sliding channel in which one of the legs of the first bracket is slidably receivable. The plates are connected by a second crosspiece. Spring loaded members supported by each plate each include a spherical head which penetrates into the sliding channel of its plate to frictionally engage the respective leg of the first bracket in the channel. Temporary release of these members enables the height of the light fixture to be easily adjusted by moving the second bracket.
