Answer:
2.44%
Explanation:
Average outstanding loan = $75,000,000
Total line of credit = $100,000,000
Unused portion = $25,000,000 ($100,000,000-$75,000,000)
Commitment fee = 0.25%
Interest rate = 3.175% (3+0.175%)
Commitment fee = Unused portion*Commitment fee rate
Commitment fee = $25,000,000*0.0025
Commitment fee = $62,500
Interest = Average outstanding balance*Interest rate
Interest = $75,000,000*0.03175
Interest = $2,381,250
Total borrowing cost = Commitment fee + Interest
Total borrowing cost = $62,500 + $2,381,250
Total borrowing cost = $2,443,750
Effective borrowing rate = Total borrowing cost / Credit limit
Effective borrowing rate = $2,443,750/$100,000,000
Effective borrowing rate = 0.0244375
Effective borrowing rate = 2.44%
