Last year the deficit here (a UK circuit) was so high an elder told me the CO wrote to the congs citing some nonsense in the Organized to do Jehovah's will book and strong armed the cash that way.
Here it is:
"Ideally, each assembly is to pay the expenses it incurs, with surplus funds being deposited in the circuit account. ...
However, if there are insufficient funds in the circuit account to pay expenses for the last assembly or to meet initial expenses for the next assembly, such as a deposit to secure the use of a facility, the circuit overseer may direct that congregations be advised of the privilege to contribute.
... elders will discuss the matter and determine what contribution thir congregation would be able to make to the circuit fund ... then handle this in their congregation by means of a resolution. "
This is in a paid for assembly hall!
