August 4, 1941, plaintiffs leased to defendant for a five-year term beginning September 15, 1941, *51 certain premises located at the corner of Almont Drive and Wilshire Boulevard in the city of Beverly Hills, Los Angeles County, “for the sole purpose of conducting thereon the business of displaying and selling new automobiles (including the servicing and repairing thereof and of selling the petroleum products of a major oil company) and for no other purpose whatsoever without the written consent of the lessor” except “to make an occasional sale of a used automobile.” Defendant agreed not to sublease or assign without plaintiffs’ written consent. On January 1,1942, the federal government ordered that the sale of new automobiles be discontinued. It modified this order on January 8, 1942, to permit sales to those engaged in military activities, and on January 20, 1942, it established a system of priorities restricting sales to persons having preferential ratings of A-l-j or higher. On March 10, 1942, defendant explained the effect of these restrictions on his business to one of the plaintiffs aiithorized to act for the others, who orally waived the restrictions in the lease as to use and subleasing and offered to reduce the rent if defendant should be unable to operate profitably. Nevertheless defendant vacated the premises on March 15, 1942, giving oral notice of repudiation of the lease to plaintiffs, which was followed by a written notice on March 24, 1942. Plaintiffs affirmed in writing on March 26th their oral waiver and, failing to persuade defendant to perform his obligations, they rented the property to other tenants pursuant to their powers under the lease in order to mitigate damages. On May 11, 1942, plaintiffs brought this action praying for declaratory relief to determine their rights under the lease, and for judgment for unpaid rent. Following a trial on the merits, the court found that the leased premises were located on one of the main traffic arteries of Los Angeles County; that they were equipped with gasoline pumps and in general adapted for the maintenance of an automobile service station; that they contained a one-story storeroom adapted to many commercial purposes; that plaintiffs had waived the restrictions in the lease and granted defendant the right to use the premises for any legitimate purpose and to sublease to any responsible party; that defendant continues to carry on the business of selling and servicing automobiles at two other places. Defendant testified that at one of these locations he sold new automobiles exclusively and when asked if he were aware that many new automobile dealers were continuing in business replied: “Sure. It *52 is just the location that I couldn’t make a go, though, of automobiles.” Although there was no finding to that effect, defendant estimated in response to inquiry by his counsel, that 90 per cent of his gross volume of business was new car sales and 10 per cent gasoline sales. The trial court held that war conditions had not terminated defendant’s obligations under the lease and gave judgment for plaintiffs, declaring the lease as modified by plaintiffs’ waiver to be in full force and effect, and ordered defendant to pay the unpaid rent with interest, less amounts received by plaintiffs from re-renting. Defendant brought this appeal, contending that the purpose for which the premises were leased was frustrated by the restrictions placed on the sale of new automobiles by the federal government, thereby terminating his duties under the lease.

“Even more clearly with respect to leases than in regard to ordinary contracts the applicability of the doctrine of frustration depends on the total or nearly total destruction of the purpose for which, in the contemplation of both parties, the transaction was entered into.”
The principles of frustration have been repeatedly applied to leases by the courts of this state
(Brown
v.
Oshiro,
Although the doctrine of frustration is akin to the doctrine of impossibility of performance (see Civ. Code, § 1511; 6 Cal.Jur. 435-450; 4 Cal.Jur Ten-year Supp. 187-192;
Taylor
V.
Caldwell, supra)
since both have developed from the commercial necessity of excusing performance in cases of extreme hardship, frustration is not a form of impossibility even under the modern definition of that term, which includes not only cases of physical impossibility but also cases of extreme impracticability of performance (see
Mineral Park Land Co.
v.
Howard,
The question in cases involving frustration is whether *54 the equities of the case, considered in the light of sound public policy, require placing the risk of a disruption or complete destruction of the contract equilibrium on defendant or plaintiff under the circumstances of a given case (Fibrosa Spolka Akcyjina v. Fairbairn Lawson Combe Barbour, Ltd. [1942], 167 L.T.R. [H.L.] 101, 112-113; see Smith, Some Practical Aspects of the Doctrine of Impossibility, 32 IlLL.Rev. 672, 675; Patterson, Constructive Conditions in Contracts, 42 Columb.L.Rev. 903, 949; 27 Cal.L.Rev. 461), and the answer depends on whether an unanticipated circumstance, the risk of which should not be fairly thrown on the promisor, has made performance vitally different from what was reasonably to be expected (6 Williston, op. cit. supra, § 1963, p. 5511; Restatement, Contracts, § 454). The purpose of a contract is to place the risks of performance upon the promisor, and the relation of the parties, terms of the contract, and circumstances surrounding its formation must be examined to determine whether it can be fairly inferred that the risk of the event that has supervened to cause the alleged frustration was not reasonably foreseeable. If it was foreseeable there should have been provision for it in the contract, and the absence of such a provision gives rise to the inference that the risk was assumed.
The doctrine of frustration has been limited to cases of extreme hardship so that businessmen, who must make their arrangements in advance, can rely with certainty on their contracts
(Anglo-Northern Trading Co.
v.
Emlyn Jones and Williams, 2
K.B. 78;
Thus laws or other governmental acts that make performance unprofitable or more difficult or expensive do not excuse the duty to perform a contractual obligation
(Sample
v.
Fresno Flume etc. Co.,
At the time the lease in the present case was executed the National Defense Act (Public Act No. 671 of the 76th Congress [54 Stats. 601], §2A), approved June 28, 1940, authorizing the President to allocate materials and mobilize industry for national defense, had been law for more than a year. The automotive industry was in the process of conversion to supply the needs of our growing mechanized army and to meet lend-lease commitments. Iceland and Greenland had been occupied by the army. Automobile sales were soaring because the public anticipated that production would soon be restricted. These facts were commonly known and it cannot be said that the risk of war and its consequences necessitating restriction of the production and sale of automobiles *56 was so remote a contingency that its risk could not be foreseen by defendant, an experienced automobile dealer. Indeed, the conditions prevailing at the time the lease was executed, and the absence of any provision in the lease contracting against the effect of war, gives rise to the inference that the risk was assumed. Defendant has therefore failed to prove that the possibility of war and its consequences on the production and sale of new automobiles was an unanticipated circumstance wholly outside the contemplation of the parties.
Nor has defendant sustained the burden of proving that the value of the lease has been destroyed. The sale of automobiles was not made impossible or illegal but merely restricted and if governmental regulation does not entirely prohibit the business to be carried on in the leased premises but only limits or restricts it, thereby making it less profitable and more difficult to continue, the lease is not terminated or the lessee excused from further performance

Fairchester Oil Co.,
Defendant contends that the lease is restrictive and that the government orders therefore destroyed its value and frustrated its purpose. Provisions that prohibit subleasing or other uses than those specified affect the value of a lease and are to be considered in determining whether its purpose has been frustrated or its value destroyed (see Owens,
The Effect of the War Upon the Rights and Liabilities of Parties to a Contract,
19 California State Bar Journal 132, 143). It must not be forgotten, however, that “The landlord has not covenanted that the tenant shall have the right to carry on the
*57
contemplated business or that the business to which the premises are by their nature or by the terms of the lease restricted shall be profitable enough to enable the tenant to pay the rent but has imposed a condition for his own benefit; and, certainly, unless and until he chooses to take advantage of it, the tenant is not deprived of the use of the premises.” (6 Williston, Contracts,
op. cit. supra,
§ 1955, p. 5485; see, also,
People
v.
Klopstock,
The consequences of applying the doctrine of frustration to a leasehold involving less than a total or nearly total destruction of the value of the leased premises would be undesirable. Confusion would result from different decisions purporting to define “substantial” frustration. Litigation would be encouraged by the repudiation of leases when lessees found their businesses less profitable because of the regulations attendant upon a national emergency. Many leases have been affected in varying degrees by the widespread governmental regulations necessitated by war conditions.
The cases that defendant relies upon are consistent with the conclusion reached herein. In
Industrial Development & Land Co.
v.
Goldschmidt, supra,
the lease provided that the premises should not be used other than as a saloon. When national prohibition made the sale of alcoholic beverages illegal, the court excused the tenant from further performance on the theory of illegality or impossibility by a change in domestic law. The doctrine of frustration might have been applied, since the purpose for which the property was leased
*58
was totally destroyed and there was nothing to show that the value of the lease was not thereby totally destroyed. In the present case the purpose was not destroyed but only restricted, and plaintiffs proved that the lease was valuable to defendant. In
Grace
v.
Croninger, supra,
the lease was for the purpose of conducting a “saloon and cigar store and for no other purpose” with provision for subleasing a portion of the premises for bootblack purposes. The monthly rental was $650. It was clear that prohibition destroyed the main purpose of the lease, but Since the premises could be used for bootblack and cigar store purposes, the lessee was not excused from his duty to pay the rent. In the present case new automobiles and gasoline may be sold under the lease as executed and any legitimate business may be conducted or the premises may be subleased under the lease as modified by plaintiff’s waiver.
