The amount made available for expenditure from the Association’s endowment in a fiscal year shall be a weighted average of:

• the prior year’s spending adjusted for inflation (weighted at 70%), and
• 5.5% of the trailing four-quarter average market value of the endowment as of the previous December (weighted at 30%).

However, the spending rate must be at least 4.5% and not more than 6.25% of the trailing four-quarter average market value of the endowment as of the previous December.
