The plaintiff appeals from a decree holding that she was not entitled to any benefits under an insurance policy issued by defendant to her deceased husband’s employer.

Plaintiff’s husband, Thomas R. O’Brien, was employed by the New York Merchandise Company as a warehouseman, and on October 14, 1963, sustained an injury arising out of and in the course of his employment.

The employer was engaged in a hazardous occupation, but had rejected the workmen’s compensation law. When O’Brien was injured there was in effect a workmen’s compensation and employers liability insurance policy issued by defendant to O’Brien’s employer. The policy covered the employer’s legal liability to its employees for injuries arising out of and in the course of their employment. The policy also contained a voluntary compensation endorsement obligating the company, under certain conditions, to pay to an injured workman the equivalent of the benefits he would have received if he and the employer had been subject to the workmen’s compensation law. The voluntary compensation endorsement provided that if any proceeding was commenced to recover damages from the employer on account of the injury, the liability of the company under the voluntary compensation endorsement would terminate.

After O’Brien was injured the defendant paid him the equivalent of workmen’s compensation benefits until the early part of 1965. On April 22,1965, O’Brien filed in the circuit court for Multnomah county an action against his employer to recover damages on account of the injury resulting from the accident of October 14, 1963. O’Brien died on May 2, 1965, while the action was still pending.

The trial court found that the filing of the damage action by O’Brien was an election between his right to receive the equivalent of workmen’s compensation benefits and his right to sue his employer for damages, and that the filing of the action terminated the liability of defendant under the voluntary compensation endorsement. We agree and affirm the decree of the trial court.

It is only necessary to add that we find no ambiguity in the policy as contended by plaintiff, and no element of waiver or estoppel in the conduct of defendant. We further find that the election made by O’Brien to sue his employer terminated defendant’s liability under the voluntary compensation endorsement.

The decree of the circuit court is affirmed.
