Asset management is a management model that emphasizes project-based management, as well as long-term and strategic planning.

Current consumption level is the amount of each utility consumed at a project during the 12-month period that ended the June 30th prior to the beginning of the applicable funding period.

Eligible unit months (EUM) are the actual number of PHA units in eligible categories expressed in months for a specified time frame and for which a PHA receives operating subsidy.

Formula amount is the amount of operating subsidy a PHA is eligible to receive, expressed in whole dollars, as determined by the Operating Fund Formula.

Formula expense is an estimate of a PHA's operating expense used in the Operating Fund Formula.

Formula income is an estimate of a PHA's non-operating subsidy revenue used in the Operating Fund Formula.

Funding period is the calendar year for which HUD will distribute operating subsidy according to the Operating Fund Formula.

Operating Fund is the account/program authorized by section 9 of the 1937 Act for making operating subsidy available to PHAs for the operation and management of public housing.

Operating Fund Formula (or Formula) means the data and calculations used under this part to determine a PHA's amount of operating subsidy for a given period.

Operating subsidy is the amount of annual contributions for operations a PHA receives each funding period under section 9 of the 1937 Act as determined by the Operating Fund Formula in this part.

Other operating costs (add-ons) means PHA expenses that are recognized as formula expenses but are not included either in the project expense level or in the utility expense level.

Payable consumption level is the amount for all utilities consumed at a project that the Formula recognizes in the computation of a PHA's utility expense level at that project.

Per unit per month (PUM) describes a dollar amount on a monthly basis per unit, such as Project Expense Level, Utility Expense Level, and formula income.

Project means each PHA project under an ACC to which the Operating Fund Formula is applicable. However, for purposes of asset management, as described in subpart H of this part, projects may be as identified under the ACC or may be a reasonable grouping of projects or portions of a project or projects under the ACC.

Project-based management is the provision of property management services that is tailored to the unique needs of each property, given the resources available to that property.

Project expense level (PEL) is the amount of estimated expenses for each project (excluding utilities and add-ons) expressed as a PUM cost.

Project units means all dwelling units in all of a PHA's projects under an ACC.

Rolling base consumption level (RBCL) is the average of the yearly consumption levels for the 36-month period ending on the June 30th that is 18 months prior to the beginning of the applicable funding period.

Transition funding is the timing and amount by which a PHA will realize increases and reductions in operating subsidy based on the new funding levels of the Operating Fund Formula.

Unit months are the total number of project units in a PHA's inventory expressed in months for a specified time frame.

Utilities means electricity, gas, heating fuel, water, and sewerage service.

Utilities expense level (UEL) is a product of the utility rate multiplied by the payable consumption level multiplied by the utilities inflation factor expressed as a PUM dollar amount.

Utility rate (rate) means the actual average rate for any given utility for the most recent 12-month period that ended the June 30th prior to the beginning of the applicable funding period.

Yearly consumption level is the actual amount of each utility consumed at a project during a 12-month period ending June 30th.
