Concentration of Credit Risk [Text Block]

Note

15

- Concentration of Credit Risk:

Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash deposits. Accounts at each institution are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to

$250,000.

As of

October 31, 2019

and

October 31, 2018,

the Company had

$1,445,000

and

$3,000,000,

respectively, in excess of the FDIC insured limit.  Management has concluded the excess does

not

represent a material risk, based on the creditworthiness  of the counter parties.
