(Bloomberg) -- JPMorgan Chase set aside 3% less to pay employees at its investment bank in the first nine months of 2014 as revenue in the division slumped, driven by a 12% drop in fixed-income trading.

The attached chart shows the accrual has gotten smaller for three straight years, falling to $8.43 billion, according to figures the New York-based firm released today.

Revenue at the division fell 6% as bond-trading slipped to $10.8 billion from $12.3 billion in the first nine months of last year. Equities-trading revenue declined 5% to $3.69 billion. Advisory revenue jumped 35% to $1.19 billion, leading a 2% increase in overall investment-banking fees.
