On April 11, 1962, in payment of a preexisting debt, Moose Valley Lumber Co. assigned to appellant, Northern Commercial Co., an account receivable due from appellee Pacific and Arctic Railway and Navigation Company in the amount of $3500.

Northern Commercial did not file notice of the assignment with the Commissioner of Administration until April 26, 1962, which was fifteen days after the event. A statute then in force provided that no assignment should be valid as against present or future creditors of the assignor unless notice of the written assignment be on file in the office of the Commissioner of Administration at the time of making the assignment or within ten days thereafter.1

*663On- August ”6, 1962, appelleé National - Hank of Alaska-garnished the debt' owed "by Pacific and Arctic Railway to Moose.' "Valley Lumber Co. in an attempt to collect a debt owed to-it by Moose Valley in'an . amount in excess of $3500. . .

Pacific and Arctic Railway, in an intér-pleader proceeding, deposited the sum of $3500 in court, requesting the court to determine who, as between Northern ' Commercial Co. and National Bank of Alaska was entitled do the sum and to make appropriate disposition.

The. superior- court ■■ found- in favor of National Bank of Alaska on the ground that the assignment from Moose Valley to Northern Commercial was invalid because notice was filed five days later than the ten day period mentioned in the statute.

Appellant contends that although the statute then in force was premised on a ten day period for filing notice of assignments, that provision did not have the effect of invalidating all assignments filed after the ten day period had passed. Appellant’s argument is that filings made after expiration of the ten day period were invalid only as to creditors “without knowledge” of the assignment and that “knowledge”, as used in the statute, includes constructive as well as actual knowledge.

Appellees argue that the provisions of the statute were explicit and provided that no assignment would be “valid” unless notice was filed within ten days of the execution of the assignment and that since the filing of notice of the assignment was not accomplished until five days after expiration of the ten day period provided for in the statute, the assignment was not valid against National Bank of Alaska, a subse-qu'ent. attachment creditor-.' Appellees---con*-... tend that there-can be no constructive notice. „ of ,an invalid assignment.

■As • counsel point out, state statutes such ,- as. Chapter. 90j SLA ,1951. were... originally enacted' as a -result of- the- decision -of the - United States Supreme ..Court -in Corn Ex- . change -National .Bank &. .Trust Company, Philadelphia, v. - Klauder.2 .. In -that case the trustee- in bankruptcy claimed,priority over- certain- assignees- of. accounts receivable made as security for loans contempor • raneously advanced. It was held that such assignments would be'Valid Against- a trustee • in bankruptcy only if the'assignments had been so' far perfected under thre applicable state-la-w-that-no bona fide purchaser from the debtor'arid nor creditor:'could-theteafter have acquired any rights in the property assigned superior to the rights of the assignee, as of the time of the filing of the petition in bankruptcy. Since state law was made the criterion for determining the question of priority, many states then enacted specific statutes. The general object of most such statutes was to give some protection to the assignee in what had become a rather widely employed method of financing, as against the claims of other creditors and the trustee in bankruptcy.3

We are of the opinion that the ten day period provided for in Chapter 90, SLA 1951 was for the convenience and protection of assignees to allow them ample time to provide the required public notice of the assignment without incurring the risk of having an intervening assignee or attachment creditor displace their priority.

There seems to be no basis in reason or business expediency for holding that failure to file notice of assignment within the ten day period has the effect of forever in*664validating the assignment as to subsequent assignees or attachment creditors.

In the case before us the assignee, appellant Northern Commercial Co., filed notice of the assignment five days after the ten day period provided for in the statute. It was not until three months later that National Bank of Alaska became an attachment creditor. During all of the preceding three months it was a matter of public record that the assignment here in question had been made. National Bank of Alaska does not allege that it was misled in any way by the lateness of Northern Commercial’s filing of notice.

We believe that the ten day relation back period provided for in the statute was intended for the protection of assignees not able, by reason of location or otherwise, to accomplish an immediate filing of notice of assignment. The late filing did not invalidate the filing as to the appellees under the circumstances of this case.4

The judgment below is reversed.
