This article provides a framework for determining, justifying, and improving financial sustainability of savings and credit programs. Credit programs have income from interest and fees. Income must pay for the cost of funds, loan write-offs, operating costs, and inflation. Reference is made to Otero and Rhyne's four levels of self-sufficiency in credit programs. The Grameen Bank is an example of Level 3 and most credit unions are level 4. Nongovernmental groups in the United Kingdom are level 1 or 2. Experience has shown that removal of subsidies did not affect the quality of services or shift benefits away from the poor. Success in serving poorer people better is attributed 1) to more money being available for lending under tighter management practices, 2) to greater openness to a variety of clients from removal of subsidy restrictions, 3) to a shift to higher interest rates that eliminate richer borrowers, and 4) to a shift to serious collection of loans which is a disincentive to more privileged borrowers. Percentages of loan loss, administration costs, cost of funds, and inflation are useful in measuring the sustainability of credit programs. Interest and fee income must also be measured. Fee repayment rates do not have a common definition of arrears, default, and write-off. A simple measure is the percentage of total costs covered by income. The World Bank recommends the Subsidy Dependence Index. Women tend to be better at repaying loans. Loan size should be related to borrowers' ability to handle the amount of the loan. Low and subsidized interest rates deter depositors and attract richer borrowers. Poorer borrowers are attracted by access to credit and not the cost of credit. Interest rates should be based on market rates. The loan payment should be no longer than necessary. Small groups of borrowers can guarantee each others loans. Group-based loan schemes work best. NGOs must project an image of being serious about loan collections and must take action immediately when a payment is missed. Good repayers should be rewarded with quick repeat loans.  相似文献

Fused silica capillary columns (Durabond) have been evaluated for the screening of more than 100 basic drugs in postmortem blood samples. The combination of these columns, nitrogen-phosphorus detectors, and SKF-525A (internal standard) allows for the simultaneous screening and quantitation of several basic drugs such as amphetamines, amitriptyline, and codeine. Approximately 2000 blood samples have been analyzed by this procedure. The use of capillary columns results in excellent baseline stability and this, together with an autosampler and data system, enables unattended overnight operation. "Double peaking" associated with splitless injection can be a problem as can sensitivity for some of the polar drugs; however, with the extraction procedure described and the equipment used, the screening of blood for basic drugs is improved when compared with packed column technology.  相似文献
