Actually, WT did not find itself in the red. They never said “operating expenses” were not being covered. They specifically stated “theocratic initiatives” they had planned (building projects, etc) were not being funded as expected.
Even if you what you say is true, costs for planned future expenditures were not going to be met, signifying at best accounting troubles.
As for their announcement regarding "swapping buildings", it says nothing regarding their financial situation. The more relevant indicators of monetary problems were the immediate and seemingly unexpected austerity measures taken beginning in 2015, including freezing most construction projects, laying off thousands of bethel workers, selling kingdom halls as well as assembly halls, etc. Herd himself announced that those measures were taken for budgetary reasons.
Slim gives an excellent summation of obvious WT financial woes here:
