First Consulting Group Inc. will delay the report of its fourth-quarter and full-year financial results by a week, the Long Beach health care consulting firm announced Tuesday.

The Long Beach consulting firm said it needed extra time to complete tax-related analysis on how to account for certain net-operating-losses for the previous year. The company plans to release the results March 13.

“The analysis is not expected to impact the company’s pre-tax operating results in any period,” First Consulting said in a statement.

Shares in First Consulting were up 48 cents, or more than 4 percent, to $12.05 in afternoon trading Tuesday on the Nasdaq.
