a) Capital structure measurement period. A company may elect to use either an historical or forecasted capital structure measurement period.
b) Measurement. Components of the capital structure must be presented on a consistent basis with respect to the capital structure, measurement period, and method (i.e., net proceeds or internal rate of return method). If one or more adjustments for known and measurable changes affecting capital structure are made, all other known and measurable changes that would affect capital structure shall be made as well. The balance of short-term components of the capital structure shall be calculated from 12 months of average monthly balances. Utilities may elect to base the long-term components of the capital structure on either average or end-of-period balances. For those utilities electing an average capital structure, average balances for each source of capital included in the capital structure, excepting individual security issuances and retirements, shall be calculated from 12 months of average monthly balances. Individual security issuances and retirements shall be time-weighted. Each monthly average shall equal the simple average of the beginning and ending monthly balances. However, monthly data need not be presented for debt and preferred stock issues that do not change during the capital structure measurement period or that change by equal monthly amounts.
c) Applicability
d) All data required under this Subpart shall be provided on a total company basis unless otherwise indicated.
