Jan 24 (Reuters) - Ameriprise Financial reported a rise in fourth-quarter adjusted profit on Wednesday, as the financial adviser benefited from higher fees and assets under management.

Increasing expectations about a soft landing for the U.S. economy - a scenario where inflation decreases without causing unemployment to go up - has buoyed markets in recent months, boosting Ameriprise's fee-based income.

The company's management and financial advice fees rose 7% to $2.28 billion in the quarter, while net investment income surged 54% to $888 million.

Total client assets at its advice and wealth management segment rose 19% to $900.5 billion.

Ameriprise's total assets under management and administration rose 15% to $1.36 trillion in the quarter compared with a year earlier, on the back of strong client net inflows and market appreciation.

Adjusted operating earnings rose to $761 million, or $7.20 per diluted share, in the three months ended Dec. 31, from $732 million, or $6.57 per diluted share, a year earlier.
