Criteria I Governments I U.S. Public Finance: U.S. Local Governments General Obligation Ratings:Methodology <br /> And Assumptions <br /> the planned or recently issued debt results in a worse score. <br /> 80. The criteria improve the final score by one point when above-average annual debt amortization(based on total direct <br /> debt)inflates the debt service as a percentage of expenditures score and masks the future flexibility stemming from an <br /> early deleveraging. The criteria do not apply this adjustment when the early amortization results from a <br /> near-to-medium term bullet maturity that will not be retired with funds on hand. Exposure to interest-rate risk or <br /> instrument provisions that cause amortization or interest-rate changes beyond the issuer's control increase the score <br /> by one point,reflecting additional uncertainty as to whether current debt service levels are representative of those <br /> going forward. Examples include unhedged variable-rate debt or higher interest rates resulting from failed <br /> remarketings in instruments such as auction-rate securities,variable-rate demand bonds, and certain direct purchase <br /> obligations. <br /> 81. An overall net debt to TMV level of above 10%worsens the score by one point,while a low level,below 3%,improves <br /> the score by one point. This statistic captures the burden of the local government's debt in addition to that of <br /> overlapping jurisdictions on the overall tax base.An atypical debt burden can present extra challenges or flexibility <br /> over and above that suggested by the individual government's debt burden alone. <br /> 82. The impact of pension and OPEB obligations depends on the degree to which such costs will likely escalate and <br /> whether the government has plans to address them. Relative to debt,governments have a higher level of flexibility to <br /> address these costs,both from a temporal payment perspective and from an obligation level perspective. Many <br /> governments have the flexibility to alter benefit levels, and some governments already have availed themselves of this <br /> ability. Most governments also can pay less than the annual required contribution without leaving the fund unable to <br /> meet actual payments in the current and following year. On the other hand, such delays accelerate the growth rate of <br /> future payments.When the potential for such accelerations exists and the increased payments increase budget stress, <br /> the final debt and contingent liabilities score worsens by one point when a specific and credible plan to address this <br /> burden is in place. Otherwise,the score worsens by two points relative to the initial score.Among the areas of analytic <br /> focus when assessing the pension and OPEB burden will be: <br /> • The required annual pension payment plus annual OPEB payment as a percentage of total governmental funds <br /> expenditures.A combined carrying charge of 10%or more will be considered elevated,however,we will consider <br /> whether we expect the elevated payments to result in lower future obligations. <br /> • The actuarial funded ratio(s) of the pension plan(s) a local government participates in or sponsors. If the ratio(s)are <br /> less than 80%,they will receive further review especially when the carrying charge is elevated.We also consider the <br /> magnitude of the unfunded obligation in tandem with the funded ratio(s)when assessing the potential for stress. <br /> • The contributions actually made to all pension plans a local government participates in or sponsors. The degree to <br /> which a local government contributes less than its full required contribution(s)could be an indication of either <br /> short-term cash flow issues or a willingness of management to defer difficult decisions. <br /> • The OPEB costs exceed 5%of total governmental funds expenditures and the local government has limited <br /> flexibility to change or amend these benefits. <br /> 83. Finally, another adjustment considers additional future contingent liabilities not yet requiring government support. <br /> While our debt burden calculation already considers other nondirect debt requiring government support and our <br /> liquidity score considers the near-term impact of any contingent liabilities,the adjustment to the debt score results <br /> WWW.STANDARDANDPOORS.COM/RATINGSDIRECT SEPTEMBER 12,2013 30 <br /> 1190266 1300881696 <br />
