ORS § 554.290
All claims against the corporation shall be paid by warrants drawn on the treasurer of the corporation and signed by the president and secretary of the board of directors. If any warrant is not paid when presented to the treasurer of the board of directors, because of lack of funds in the treasury, that fact shall be indorsed on the warrant and the warrant shall draw interest thereafter at a rate determined by the board until there is money in hand to pay the amount of the warrant and the interest then accumulated. No interest shall be allowed on warrants after sufficient funds are in the treasury to pay the indorsed warrants and interest. The secretary of the board shall give notice to the payee or other holder if known whenever sufficient funds are available to pay outstanding warrants. Warrants shall be numbered, drawn against the proper fund, and paid from such fund in the order of issuance. The board of directors shall levy an assessment each year of sufficient amount of money to pay the outstanding warrants. No warrants shall be issued the payment of which in the ensuing year inclusive of the assessments required for all other purposes will exceed the annual assessment limit fixed in the landowners' recorded notice, or the aggregate indebtedness of which with all other indebtedness for other purposes than operation and maintenance will exceed the total benefits to accrue to the land described in the articles of incorporation as stated in the recorded landowners' notice.
