W.R. PETERSON, J.
The parties submitted these cases to the trial court on agreed statements of fact and motions for summary disposition. Plaintiff appeals as of right from the resulting final judgments in favor of the defendants.
Plaintiff is a Michigan manufacturer which purchased an umbrella, or excess, liability insurance policy from defendant First State Insurance Company for the period October 1, 1982, to October 1, 1983, which insurance was designed to insure against liability claims in excess of the $1,000,000 coverage provided by an underlying general liability insurance policy with Ambassador Insurance Company. For the period October 1, 1983, to October 1, 1984, plaintiff purchased a similar umbrella policy from Western Employers Insurance Company with $1,000,000 underlying general liability insurance provided by Union Indemnity Insurance Company of New York.
Products liability suits have been commenced against plaintiff for alleged causes of action arising during the terms of each of the insurance policies. Each of the general liability carriers became insolvent and were ordered into court-supervised liquidation. Plaintiff made demand on both defendants for coverage and that they assume defense in the pending actions.[1] Each defendant refused to assume the defense of the pending actions and denied liability for payment of claims until they exceeded the $1,000,000 upper limit of the underlying *606 general liability policies. These actions resulted.
Plaintiff's claim is that the umbrella coverage is not for liability in excess of the amount of $1,000,000 but rather for liability in excess of whatever amount may be recoverable from the carrier of the underlying $1,000,000 general liability insurance, e.g., if the general liability carrier becomes insolvent, the lower limit of the excess coverage "drops down" from $1,000,000 to whatever amount can be recovered from the insolvent general liability carrier. Plaintiff in reality seeks to make the umbrella carrier an insurer not only against the liabilities described in the contract but also of the solvency of the general insurance carrier.
Defendants, in turn, argue that the umbrella insurance provides coverage for liability in excess of $1,000,000. Had their policies said that and no more in describing the intended coverage, plaintiff clearly would have no claim. The insuring agreements of the policies may have once had "plain English" origins, simply defining the coverage in that way, but evolution through generations of legal usage have rendered the present insuring agreements prolix. The translation, however, is the same, for the coverage is still defined as being for an excess over an amount, which amount is elsewhere identified as $1,000,000. The insuring agreement of the First State policy, for instance,[2] provides:
I. COVERAGE
To indemnify the INSURED for ULTIMATE NET LOSS, as defined hereinafter, in excess of RETAINED LIMIT, as herein stated....
* * *
*607 II. UNDERLYING LIMIT  RETAINED LIMIT
The Company shall be liable only for the ULTIMATE NET LOSS in excess of the greater of the INSURED'S:
A. UNDERLYING LIMIT  an amount equal to the limits of liability indicated beside the underlying insurance listed in the Schedule A of underlying insurance[[3]] ...; or,
B. RETAINED LIMIT  The amount specified in Item 3 I B of the declarations as the result of any one occurrence not covered by said underlying insurance, and which shall be borne by the INSURED.[[4]] [Emphasis added.]
These provisions of the policy thus state the threshold of liability level thereof as an amount which is the policy limit of the underlying general liability insurance, $1,000,000.
Plaintiff contends, however, that this language is inconsistent with the language contained in the declarations page of the policies which speaks of the limits of liability as follows:
[Western Employers policy] Limits of Liability: The limit of the Company's liability shall be as stated herein, subject to all the terms of this policy having reference thereto.
A. $10,000,000. Single Limit any one occurrence combined Personal Injury, Property Damage and Advertising Injury or Damage in excess of:
(1) UNDERLYING LIMIT
The amount recoverable under the underlying insurance as set out in the Schedule of Underlying Insurance attached or
(2) RETAINED LIMIT
$10,000. Ultimate Net Loss as the result of any *608 one occurrence not covered by said underlying insurance.
B. $10,000,000. Limit in the aggregate for each annual period with respect to:
(1) The Products Hazard or Completed Operations Hazard or both combined, or
(2) Occupational Disease sustained by employees of the insured. [Emphasis added.]
Plaintiff contends that this definition of the underlying limit in the declarations, unlike the language in the insuring agreement, does not indicate a set and specific amount; rather, plaintiff claims, the "amount recoverable" speaks to the ability of the primary carrier to pay out the limits of its policy, thereby defining the underlying limit as a variable amount, the policy limit of the underlying insurance or whatever amount is recoverable thereunder. Given this conflict between the language in the insuring agreement had the declarations, plaintiff argues, there is an ambiguity which, under accepted principles of insurance law, must be construed in favor of the insured.[5]
The trial judge herein rejected that argument, pointing out that the language in the declarations to which plaintiff points begins: "The limit of the Company's liability shall be as stated herein, subject to all of the terms of this policy having reference thereto." (Emphasis added.) We agree with this conclusion that the policies, read as a whole, are unambiguous.
The financial vicissitudes of the insurance industry in recent years have spawned numerous similar cases, though this is the first of its genre in Michigan. Though there have been some differences in the language of the various insurance contracts construed in such cases, the result in *609 most jurisdictions has been to reject the so-called "drop down" theory.[6] That accords with the recognized intent of the parties, the purpose of the umbrella coverage being to provide, at a relatively low premium, extended coverage up to high limits, over and above primary insurance coverage. 8A Appelman, Insurance Law & Practice, § 4909.85, pp 452-457. No one has seriously contended that such inexpensive excess coverage was intended by the parties to provide primary insurance, as well, in the event of the insolvency of the primary carrier. In Continental Marble & Granite Co, Inc v Canal Ins Co, 785 F2d 1258, 1259 (CA 5, 1986), the Court said:
We therefore look to the possible consequences *610 of the rule Continental Marble propounds. Imposing the duty of indemnification on Canal would, in effect, transmogrify the policy into one guaranteeing the solvency of whatever primary insurer the insured might choose. See Golden Isles Hospitals, Inc v Continental Casualty Co, 327 So 2d 789, 790 (Fla App, 1976). An excess liability insurer obviously does not anticipate this heavy onus:
"Excess or secondary coverage is coverage whereby, under the terms of the policy, liability attaches only after a predetermined amount of primary coverage has been exhausted. A second insurer thus greatly reduces his risk of loss. This reduced risk is reflected in the cost of the policy."

Whitehead v Fleet Towing Co, 110 Ill App 3d 758; 66 Ill Dec 449; 442 NE2d 1362, 1366 (1982). Continental Marble's proposed rule would require insurance companies to scrutinize one another's financial well-being before issuing secondary policies. The insurance world is complex enough; to impose this additional burden on companies such as Canal would only further our legal system's lamentable trend of complicating commercial relationships and transactions.
Where a contrary result has been reached, it has been predicated upon the presence of language in the policy from which, the court has found, a policyholder might draw a reasonable expectation of coverage, contrary to other language in the policy denying coverage, thereby creating an ambiguity which is resolved in favor of the insured.[7] This is plaintiff's theory. To reach that result, *611 however, one may not simply pick particular language from the contract to claim either a reasonable expectation of coverage or ambiguity. While, as noted above, it is hornbook law that ambiguities in insurance contracts are to be resolved in favor of the insured, it is also hornbook law that contracts, of insurance and otherwise, are to be read as a whole to determine the intent of the parties. Royal Globe Ins Cos v Frankenmuth Mutual Ins Co, 419 Mich 565; 357 NW2d 652 (1984). As the Court noted in Raska v Farm Bureau Mutual Ins Co, 412 Mich 355, 362; 314 NW2d 440 (1982):
A contract is said to be ambiguous when its words may reasonably be understood in different ways.
If a fair reading of the entire contract of insurance leads one to understand that there is coverage under particular circumstances and another fair reading of it leads one to understand there is no coverage under the same circumstances the contract is ambiguous and should be construed against its drafter and in favor of coverage.
Yet if a contract, however inartfully worded or clumsily arranged, fairly admits of but one interpretation it may not be said to be ambiguous or, indeed, fatally unclear.
As noted above, we find the insuring agreement of the contract herein to clearly provide coverage in excess of a stated amount, the amount "indicated beside the underlying insurance listed ...." Other provisions of the policies are to the same effect, e.g.:
[First State policy] CONDITIONS:
* * *
G.... Coverage under this policy shall not apply unless and until the INSURED, or the INSURED'S *612 underlying insurer, shall be obligated to pay the amount of the UNDERLYING LIMIT or REATINED LIMIT . .. .
* * *
I.... If underlying insurance applicable in any one OCCURRENCE is exhausted by payment of judgment or settlement on behalf of the INSURED, the COMPANY shall be obligated to assume charge of the settlement or defense of any claim or proceeding against the INSURED resulting from the same occurrence ...
* * *
O.... It is warranted by the INSURED that the underlying policy(ies) listed in Schedule A, or renewals or replacements thereof not more restrictive in coverage, shall be maintained in force during the currency of this policy, except for any reduction in the aggregate limit(s) contained therein solely by payment of claims in respect of OCCURRENCES happening during the period of this policy. In the event of failure of the INSURED so to maintain such policy(ies) in force, the Insurance afforded by this policy shall apply in the same manner it would have applied had such policy(ies) been so maintained in force."[[8]] [Emphasis added.]
From the use of the disjunctive "or" in condition G, it is clear that there is no coverage until the full amount of the underlying limit has been reached by casualty occurrences resulting in the obligation of either the insured or the underlying carrier to pay the same. Radiator Specialty v First *613 State Ins Co, 651 F Supp 439, 442 (WD NC, 1987), aff'd 836 F2d 193 (CA 4, 1987).
Conditions I and O reinforce the insuring agreements by making it clear that the obligations of the excess carrier are triggered only by occurrences as a result of which the underlying insurance is exhausted by payment of judgment or settlement. Insolvency is neither an "occurrence" within the meaning of the policy nor is the resultant uncollectibility of the underlying policy an exhaustion thereof by payment or settlement. United States Fire Ins Co, Inc v Capital Ford Truck Sales, Inc, 257 Ga 77; 355 SE2d 428 (1987); Value City, Inc v Integrity Ins Co, 30 Ohio App 3d 274; 508 NE2d 184 (1986); Molina v United States Fire Ins Co, 574 F2d 1176 (CA 4, 1978).
In addition, in the First State policy, the applicable casualty endorsement (FF 6) reads as follows:
It is agreed that this policy shall not apply to any liability for personal injury or property damages arising out of products or completed operations as defined in this policy, unless such liability is covered by valid and collectible underlying insurance as described in the schedule of underlying insurance, and then only for such hazards for which coverage is afforded under said underlying insurance. [Emphasis added.]
The general rule, in Michigan as elsewhere, is that, if there is an ambiguity such that all parts of the contract cannot be harmonized, the language of the policy endorsement or rider controls. Peterson v Zurich Ins Co, 57 Mich App 385, 392; 225 NW2d 776 (1975). All of the language of the policies proper, and of endorsement FF 6 of the First State policy, is consistent with the language of the insuring agreements, and the language of the declarations pages in speaking of the limits of *614 liability expressly provides that it is "subject to all the terms of this policy." Looking at the policies as a whole, therefore, we agree with the trial court and the majority of other courts addressing similar claims that there is no ambiguity therein.
Among the jurisdictions arriving at a different result is California. Reserve Ins Co v Pisciotta, 30 Cal 3d 800; 180 Cal Rptr 628; 640 P2d 764 (1982), involved an umbrella policy with language in the declarations similar to that in the instant case. The California Supreme Court found that "amount recoverable" could be construed in two different ways, i.e., either as the dollar limits theoretically recoverable under the primary policy, or as the dollar amount actually paid by the primary carrier. Finding the meaning ambiguous, the California court held that the policy had to be construed in favor of the insured. The risk of insolvency of the primary carrier, therefore, was within the scope of the excess policy coverage.[9] While we would disagree with the reasoning of the California court in finding an ambiguity from the declarations language alone without attempting to construe the contract as a whole, we would be obliged to follow that precedent as to the Western Employers contract if it is governed by the law of Western Employers' home state, California, as plaintiff contends.[10]
The parties agree that the place of making the *615 contract determines the applicable law as between the states, and that the contract is deemed to have been made in the state where the last act necessary to make it a binding agreement took place. Ohio v Eubank, 295 Mich 230; 294 NW 166 (1940). There are no Michigan cases defining the last act necessary to complete an insurance contract, but a federal case applying Michigan law held that, where an insurance policy provides, as do the policies herein, that the policy shall not be valid until countersigned, countersigning is the last act and the place of countersigning is the place where the contract was made. Chrysler Corp v Ins Co of North America, 328 F Supp 445 (ED Mich, 1971). And see 43 Am Jur 2d, Insurance, § 323, p 396.
The Western Employers policy provided that it was not valid unless countersigned by an authorized representative. As is typical, there is no place for a countersignature on the body of the policy but only on the attached declarations page and the endorsements. Neither the declarations page nor the five endorsements attached at issuance were countersigned,[11] yet the parties stipulated that there was a valid contract. Endorsement 5, which was not countersigned, was a countersignature endorsement reading as follows:
It is agreed that the signature appearing on this endorsement is the signature of a person duly authorized to countersign on behalf of the Company in the state designated above and which is appended hereto in conformity with the insurance laws of that state.
Despite the lack of a countersignature on the countersignature endorsement, the trial judge *616 found that the parties intended that the countersignature endorsement be a part of the agreement and that, therefore the parties intended the contract to be a Michigan contract. Neither party has discussed the reason for the countersignature endorsement but the language thereof saying that it "is appended... in conformity with the insurance laws of that state" suggests that Michigan law requires such an endorsement. Such a requirement does exist in some states to assure that the law of such states would govern contracts of insurance entered into by the citizens thereof. That was once the law in Michigan. 1945 PA 223 required that contracts of insurance by foreign insurers doing business to Michigan had to be countersigned by their Michigan resident agents. Although that requirement was deleted by 1972 PA 133, the endorsement conforming to the former statute could only have been intended to meet that former statutory purpose. The Western Employers contract, therefore, is a Michigan contract, construed as we have construed it above and not according to California precedents.
The First State contract was countersigned in Massachusetts and the parties agree that the law of that state is controlling. Massachusetts precedents construing insurance contracts are essentially the same as those of Michigan.[12]
Two recent Massachusetts cases found ambiguity in umbrella policies and held that the coverage of the excess carriers dropped down to provide primary *617 coverage when the carrier of the underlying coverage becomes insolvent. Massachusetts Insurers Insolvency Fund v Continental Casualty Co, 399 Mass 598; 506 NE2d 118 (1987); Gulezian v Lincoln Ins Co, 399 Mass 606; 506 NE2d 123 (1987). Because of the particular language of the policies there involved, called peculiar by the Massachusetts court, the cases are distinguishable and inapplicable to the First State policy herein. Both involved language not found in the First State policy and did not have language found in the First State policy.
In Gulezian, Section III of the insuring agreements spoke of "applicable limits" of liability of the underlying insurance. In the unusual structure of Section III, the Court found that "applicable" was synonymous with "collectible." The Gulezian court's interpretation of "applicable" as "collectible" was reinforced by the "Other Insurance" condition, which said:
"The insurance afforded by this Policy shall be excess insurance over any other valid and collectible insurance available to the Insured . .. ." [399 Mass 611. Emphasis in original.]
The First State policy does not use the word "collectible" in its conditions, nor does the insuring agreement therein use the adjective "applicable" in describing the limits of the underlying insurance, so the rationale of Gulezian defining the same in terms of collectibility does not exist here.
In Continental Casualty, the policy provided:
[I]f the applicable limit of the underlying insurance is less than as stated in the schedule of underlying insurance because the aggregate limit of liability of the underlying insurance has been *618 reduced, this policy becomes excess of such reduced limit of liability. [399 Mass 600, n 3. Emphasis added.]
The court said of this language that "an excess policy that says without limitation that it drops down when the underlying coverage is reduced provides first dollar coverage when the primary insurer becomes insolvent." 399 Mass 601. (Emphasis added.) Unlike the Continental Casualty policy, the comparable provision of the First State policy has an express limitation, speaking of reduction in the aggregate limits of the underlying policy "solely by payment of claims." Reduction by any other cause, including insolvency of the underlying carrier, is clearly excluded.
Gulezian and Continental Casualty are thus inapplicable to the First State policy. We note that McNeal v First State Ins Co, an unpublished 1987 opinion of the Third Circuit, see 822 F2d 53, dealt with a First State policy identical to that here involved and, in applying Massachusetts law, distinguished both Gulezian and Continental Casualty to construe the policy as we have. We think that McNeal is an accurate application of Massachusetts law.
Affirmed.

[7]  Reserve Ins Co v Pisciotta, Gross v Houston Fire & Casualty Ins Co, MacNeal v Interstate Fire & Casualty, Massachusetts Insurers Insolvency Fund v Continental Casualty Co, and Gulezian v Lincoln Ins Co, supra, n 5.

We note that plaintiff contends that Geerdes v St Paul Fire & Marine Ins Co, 128 Mich App 730; 341 NW2d 195 (1983), is among the cases reaching a "drop down" result. Geerdes, however, involved quite a different question, how to compute the underlying limit when no coverage is provided by the underlying insurance but other unscheduled insurance did provide coverage.
[8]  The language of Condition O in the Western Employers policy militates even more strongly against plaintiff's argument, reading as follows:

In the event of failure by the insured to maintain such policy(ies) in force for any reason, including but not limited to bankruptcy of the insured or any underlying insurer, the insurance afforded by this policy shall apply in the same manner it would have applied had such policy(ies) been so maintained in force. [Emphasis added.]
[9]  In so holding, the court in Pisciotta based its decision on the wording of the policy and repudiated the seemingly unqualified statement of an earlier decision, McConnell v Underwriters at Lloyds, 56 Cal 2d 637; 16 Cal Rptr 362; 365 P2d 418 (1961), that "insolvency of a primary insurer gives rise to liability under the excess policy." To like effect, see Fageol Truck & Coach Co v Pacific Indemnity Co, 18 Cal 2d 748; 117 P2d 669 (1941).
[10]  California insurance policies are governed not only by the statutory law but by the decisional law of that state in effect at the time of issuance of the policy. Interinsurance Exchange of the Automobile Club of Southern California v Ohio Casualty Ins Co, 58 Cal 2d 142; 23 Cal Rptr 592; 373 P2d 640 (1962).
[11]  There were later endorsements altering the coverage of the original contract which were countersigned.
[12]  "Policies of insurance, like all other contracts, must be reasonably construed by giving to the words contained therein their usual and ordinary significance ... and by construing the various portions of the policy as parts of a single contract of insurance without according undue emphasis to any particular part over another; but if the terms of the policy are ambiguous then every doubt is to be resolved against the insurer." Woogmaster v Liverpool & London & Globe Ins Co, Ltd, 312 Mass 479, 481; 45 NE2d 394 (1942) (emphasis added).
