Criteria I Governments I U.S. Public Finance: U.S. Local Governments General Obligation Ratings:Methodology <br /> And Assumptions <br /> levels reflect their additional spending power coming from parent financing or student loans. Participation in a broader <br /> metropolitan area may bring nonresident spending into a community or provide additional job opportunities for <br /> residents beyond its borders--especially when the metropolitan area is economically strong. <br /> 44. By contrast,income and TMV per capita may fail to account for additional risks. The impact on income and economic <br /> activity from job losses may not immediately show up in income levels and market prices, and such losses are more <br /> likely to occur in more cyclical and concentrated tax bases. Because they do not exhibit strong cyclicality, <br /> concentration in the education/health,government, and transportation,trade and utilities sectors are not considered <br /> for this adjustment. County-level unemployment rates are used to reflect the wider view of the local economy. <br /> Population declines may also dampen the impact on per capita measures, and high Dependent Population levels can <br /> mean additional service requirements or different levels of willingness to support tax increases. <br /> 45. We assess participation in a larger broad and diversified economy at the Metropolitan Statistical Area(MSA)level. <br /> When the MSA is deemed to be broad and diverse, a positive adjustment of one point is applied to the initial economic <br /> score. The determination is based on an evaluation of three components--employment diversity, employment growth, <br /> and the employment base. Each of the three components is scored as strong,moderate, or weak and is equally <br /> weighted. Strong and weak scores offset each other,while a moderate score remains neutral. MSAs are considered to <br /> be broad and diverse when the net score of the three components is strong, and are not considered broad and diverse <br /> when the net score is weak. If the net score is moderate, applying the broad and diverse adjustment to the initial <br /> economic score may be warranted if we determine the local government benefits significantly from participation <br /> within its respective MSA. <br /> 46. Employment diversity within an MSA is primarily assessed using a Herfindahl Index that includes the share of total <br /> employment distributed across 12 general employment sectors. For this index,we consider less than 0.15 to be strong, <br /> between 0.15 and 0.18 to be moderate, and greater than 0.18 to be weak. Employment growth is primarily measured <br /> by the percentage change in total employment within an MSA for the prior five-year period. For this measure,we <br /> consider an MSA with a rate better than the sum of all MSAs as strong;if the MSA's rate is worse but within three <br /> percentage points of the sum of all MSAs it is considered moderate, and a rate more than three percentage points <br /> worse is considered weak. The employment base measures total employment within the MSAs across all sectors. For <br /> this measure,we consider population greater than 250,000 to be strong,between 100,000 and 250,000 to be moderate, <br /> and less than 100,000 to be weak. <br /> 47. Additional considerations include employment concentration within specific sectors if. 1)the Herfindahl index is <br /> greater than 0.067, excluding the education/health,government, and transportation,trade, and utilities sectors, or 2) <br /> any volatile sector is more than double the level found in the sum of all MSAs and a large 10-year percentage decline <br /> in total employment(greater than 10%). If any of these considerations exist,they may reduce the overall score from <br /> strong to moderate or moderate to weak. <br /> E. Management Score <br /> 48.
