Amber Blue also owns Amber's Alarms, a manufacturer of alarm clocks. On March 1 of last year, Bloomington Bank ("BB") loaned $250,000 to Amber's Alarms. To secure repayment of that loan, Amber's Alarms granted BB a security interest in all of its equipment. During the remainder of the year, BB made additional loans to Amber's Alarms. Amber's Alarms also bought additional equipment. Specifically, Amber's Alarms engaged in the following transactions. March 1 BB advanced Amber's Alarms $250,000 Amber's Alarms executed a note in that amount along with a security agreement Value of Amber's Alarms manufacturing equipment at the time was $400,000 March 15 BB advanced another $200,000 April 12 Amber's Alarms purchased a spring loader machine for $150,000 May 14 Amber's Alarms purchased a gear-making machine for $100,000 August 4 BB advanced another $250,000 On September 15, Amber's Alarms defaulted on its obligations to BB. It had not repaid any principal amounts on the loans discussed above. Amber also would like to know what is the amount of BB's secured claim against Amber's Alarms? [ In answering this question, assume that the security agreement executed on March 1 included a future advances clause, but not an after-acquired property clause. Also, do not take into account any interest that may have accrued on the loans or any changes in the value of the equipment.]
