You are the chief executive officer of Money Games Inc.(MGI), which has begun to market Borrow & Spend, a video game set in the world of finance. To buy ads, MGI borrows $50,000 from First Savings Bank. On MGI's behalf, you sign a note for the loan and offer its accounts receivable as collateral. You sign a security agreement that describes the collateral. The bank does not file a financing statement.

Has the banks security interest attached?
If so, when?
