In this study, I provide evidence that the valuation allowance for deferred tax assets helps predict the future creditworthiness of a firm. Under the provisions of SFAS No. 109, a firm records a deferred tax asset provided it expects to generate sufficient taxable income to realize the asset in the form of tax savings in the future. If a firm does not expect to generate sufficient taxable income to realize the asset, then a valuation allowance is created to reduce the balance. As a result, the valuation allowance indicates management's expectation of future taxable income, which could be informative in predicting the ability of the firm to make future interest and principal payments on debt. Alternatively, the valuation allowance may not be informative regarding creditworthiness if it is a result of overly conservative accounting practices or if it is used as an earnings management tool. I document a negative association between material increases in the valuation allowance and contemporaneous and future changes in credit ratings, evidence that is consistent with the valuation allowance providing a summary measure of a decline in firms' creditworthiness.
