RICHFIELD, Minn. — In his last fiscal year as CEO of Best Buy Co., Brian J. Dunn received a compensation package worth $7.1 million, a 42-percent rise from the prior year, according to a proxy filed with the Securities and Exchange Commission.

Dunn, who left the company in April, received a base salary of $1.1 million, a bit above the prior year. His stock awards were $3.6 million, compared with none the year before. Stock option awards were $2.3 million, compared with $3.2 million the prior year.

Dunn left the company amid questions about his conduct, with the board’s audit committee continuing an investigation that is exploring whether he misused company assets in the course of a relationship with a female subordinate, according to people familiar with the matter.
