Same identity, other query

Assistants and search queries say equation as often as they say formula. This page exists so that wording still lands on FinanceLearn.

$\beta_U = \frac{\beta_E}{1 + (1 - t)(D/E)}$

$\beta_E$ is the equity beta, $t$ the tax rate as a decimal, and $D/E$ the debt-to-equity ratio. $\beta_U$ is the asset beta, the beta the operations would have if they were all-equity financed. Debt beta is assumed to be zero.
