NEW YORK (AP) — JPMorgan Chase & Co. saw its third-quarter profits rise 22 percent from a year earlier, helped by a tax benefit. But the bank's core results still missed analysts' expectations as revenue declined in most of JPMorgan's businesses.

The largest U.S. bank by assets said Tuesday it earned $6.27 billion after payments to preferred shareholders, up from a profit of $5.13 billion a year earlier.

On a per share basis, the bank earned $1.68 per share, compared with $1.35 per share a year earlier.

Removing one-time items, including a $2.2 billion tax benefit from issues related to the financial crisis, JPMorgan said it earned $1.32 a share, which missed analysts' estimates of $1.37 per share.

Net revenue at the bank totaled $22.8 billion, compared with $24.5 billion in the same period a year earlier.

JPMorgan Chase's consumer banking division, its largest business by revenue and net income, reported a 4 percent rise in profits as revenues fell 4 percent. The decline in revenues was primarily tied to lower mortgage income.

JPMorgan has been aggressively cutting costs in its consumer bank through layoffs, attrition, branch closures and lower staffing levels. The consumer bank's headcount is down roughly 10,000 workers year-to-date.

In its corporate and investment banking division, the bank reported net income of $1.46 billion, down 13 percent from a year earlier. JPMorgan Chief Financial Officer Marianne Lake said the summer's "generally quite challenging" market conditions led to a decline in revenue in the division. Lower commodity prices also impacted the results.

Lower commodity prices also indirectly impacted JPMorgan's credit costs. The bank had to take out higher loan reserves to cover loans given to oil and gas companies.

JPMorgan shares were down 1.2 percent to $60.99 in after-market trading.
