The principal issues in this case are (a) whether The Mechanics National Bank of Worcester (bank) violated its contractual obligations to Thomas F. Killeen (Killeen) when, on June 25,1974, it foreclosed on 28,500 shares of stock (stock) in Certain-Teed Products *102 Corporation (company) pledged by Killeen as security for certain loans from the bank, and (b) if the bank wrongfully foreclosed on the stock, what the proper measure of damages is. We conclude that the bank wrongfully foreclosed on the stock and that Killeen is entitled to damages measured by the highest price at which shares of stock in the company sold on the New York Stock Exchange on June 25, 1974.
We must also decide the validity of a mortgage on the Killeens’ home, given to the bank as additional security by Killeen and his wife (Killeens) on June 19, 1974. The Killeens argue that the bank violated G. L. c. 93A and G. L. c. 140C in the course of obtaining that mortgage. We agree with the judge below that the Killeens are not entitled to relief under either G. L. c. 93A or G. L. c. 140C.
The Facts
The basic facts found by the judge are as follows. On June 25, 1974, Killeen, who had borrowed funds from the bank over the previous fifteen years, was indebted to the bank on three notes, each of which was a renewal of an earlier note. The first note, in the principal amount of $10,630.29 and bearing interest at the rate of 9.5% a year, was given on February 19, 1974, and due on August 19, 1974. The second note, in the principal amount of $176,-770.92, with interest at the rate of 10.5% a year, was given on April 30, 1974, and due on July 30, 1974. The third note, given on June 5, 1974, was in the principal amount of $152,974.82, bore interest at the rate of 11.5% a year, and was due on December 5,1974. The total obligation on these threé notes at their respective maturities was approximately $355,000. Each of these notes was secured by the stock and by other shares of stock, having a relatively low value, in another company. 2 All three of *103 the notes were executed on identical forms, which had been printed for the bank. The borrower agreed to deliver additional' security or make payments on account to the bank’s satisfaction, if the bank should deem the security already given to be insufficient because of a decline in its market value. Each note further provided that Killeen’s obligations under it "shall, at the option of [the] Bank, become immediately due and payable upon ... [IV] [the] Bank deeming itself insecure.”
Shares of stock in the company had been selling on the New York Stock Exchange at more than $15 a share at the end of April, 1974, and the collateral pledged by Killeen was then worth more than $500,000. In the early part of June, 1974, however, the market price of the company’s stock had fallen to just over $11 a share and the value of the collateral was less than $390,000. During the middle of June, the company’s stock was selling at approximately $9 a share.
A day or two before the execution of the renewal note of June 5, 1974, Killeen had a conversation with a Mr. Kettell (Kettell), a vice president of the bank, who was in charge of the bank’s loans to Killeen. He told Killeen that the bank was concerned by the declining market value of the stock. The bank, however, did renew an earlier loan on June 5, 1974. (third note).
Kettell had a further conversation with Killeen on June 10,1974, at which time the value of all the security pledged to the bank was less than the obligations at maturity of the three notes. Kettell stated that the bank was feeling insecure with respect to the pledged collateral. He demanded additional security and said the bank would need a mortgage on the Killeens’ home. Killeen pleaded for a ten-day delay, which was granted. There was no discussion of the sale of the pledged collateral.
*104 On June 14, 1974, Kettell telephoned Killeen and pressed him for a mortgage on the Killeens’ home. Kettell gave Killeen no assurance that the collateral would not be sold but rather indicated that a sale was a possibility. The Killeens executed a mortgage on their home on June 19, 1974. The property was unencumbered and had a value of at least $60,000. Two copies of a notice required under the Truth-in-Lending Act, G. L. c. 140C, were given to the Killeens. The Killeens’ right to rescind the mortgage on their home, according to the Truth-in-Lending Act (see G. L. c. 140C, § 8), expired at midnight on June 24, a Monday.
On June 24, 1974, the bank’s loan committee decided to sell the stock. The judge found that the bank "was feeling insecure.” On June 25, 1974, Kettell advised the Killeens that the bank was selling all the stock. On June 24 and 25, the stock was selling at a slightly higher price than on June 19, the day the mortgage was given. Kettell did not tell Killeen that the bank had accelerated the due dates of the notes. He did not tell Killeen that the notes had become due and payable. He did not demand payment of the notes. During the afternoon of June 25, 1974, the bank placed an order with a broker to sell the 28,500 pledged shares. These securities were sold, as the judge ruled, in a commercially reasonable manner, in various blocks during June 25, 26, 27, and 28, yielding net proceeds of approximately $238,000. The highest price at which the company’s stock sold on June 25,1974, was $10 a share, and the lowest was $9 % a share. The highest price per share paid for any share sold for the bank was 9%, obtained on the first sale of 100 shares in the afternoon of June 25. The bank applied the proceeds first toward the satisfaction of all obligations then alleged to be due under the third note, the one with the highest interest rate, and then toward the principal obligation under the second note.
*105 Proceedings Below
The dispute between the bank and the Killeens came to litigation in the following fashion. On July 17, 1974, the Killeens wrote the bank purporting to cancel the mortgage. On July 22, 1974, counsel for the Killeens sent the bank a demand letter under G. L. c. 93A, demanding rescission of the mortgage and damages for the wrongful sale of the stock. Four days later, the bank filed a complaint for declaratory relief in the Superior Court, seeking a determination that the Killeens had no right on July 17, 1974, to rescind the mortgage and that the mortgage remained in full force and effect. The Killeens counterclaimed, alleging violations of G. L. c. 93A and G. L. c. 140C, and seeking damages for the wrongful sale of the stock, rescission of the mortgage, and other relief. The bank then counterclaimed for the balance due on the first and second notes.
The judge ruled that the bank violated its contract with the Killeens by selling the stock as it did. He assessed damages based on the fair market value of the stock determined by the price per share (9%) at which the first block of shares was sold on June 25, 1974. He ordered the entry of judgment for the bank based on the balance of Killeen’s obligations to the bank reduced by (a) the value of the shares of stock on June 25, 1974, as determined by him, 3 and (b) the proceeds of the sale of the pledged life insurance policies. The judge ruled that the mortgage was valid and enforceable as to any debt owed to the bank by Killeen. He ruled that there was no violation of G. L. c. 93A or G. L. c. 140C. The Killeens and the bank have appealed from a judgment which was entered in accordance with the judge’s ruling.
*106 The Bank’s Right of Foreclosure
Killeen argues that the bank exceeded its rights in foreclosing on the stock on June 25, 1974. He challenges the judge’s implied finding that the bank in good faith deemed itself insecure. He argues further that the maturity dates of the notes were not accelerated, and that, in any event, he was not in default on any obligation because he had no reasonable opportunity to make any payment to the bank. The judge ruled that Killeen was not in default on the notes when the bank foreclosed on the stock. We agree with that conclusion.
By the terms of the notes, Killeen’s obligations were not accelerated automatically when the bank deemed itself insecure. See
Grozier
v.
Post Publishing Co.,
Even if we assume that the bank in good faith deemed itself insecure and that it accelerated the maturity dates of the notes, the bank had the right to foreclose on the stock only in the event of a default by Killeen. See G. L. c. 106, §§ 9-501, 9-504(1). The essential question is whether, on June 25, 1974, when the bank foreclosed on the *107 stock, Killeen was in default on his obligations to the bank. Cases relied on by the bank concerning the right of a creditor to proceed against collateral without notice or demand after there has been a default have no bearing until it is established that there was a default.
The rights of the parties are determined by the contractual agreement between them. See
Cassiani
v.
Bellino,
Certainly, Killeen could not read the bank’s corporate mind and know that the notes were due. He was entitled to some notice that they were due, and not simply a statement that the stock was to be sold. After such notice, Killeen was entitled further to a reasonable opportunity to satisfy his obligations. That opportunity extended at least through the bank’s business day on June 25, 1974, and perhaps beyond. 6 Because no such opportunity was *108 extended to Killeen and thus there was no default, the bank exceeded its contractual rights in foreclosing on the stock when it did. 7
We stress again that, in the absence of statutory restrictions, the rights of the parties to secured transactions are controlled by the agreement between them. Under a different form of note, the course followed by the bank would have been permissible, subject to any statutory provisions governing that relationship.
Before determining what damages, if any, Killeen is entitled to for the bank’s breach of contract, we consider the Killeens’ claim that they have certain statutory rights in the circumstances.
Relief under G. L. c. 93A and G. L. c. 140C
The Killeens are not entitled to relief under either G. L. c. 93A or G. L. c. 140C. The judge was correct in finding and ruling that the bank did not engage in an *109 unfair or deceptive act or practice as defined in G. L. c. 93A, § 2(a). There was no violation of G. L. c. 140C, the Truth-in-Lending Act, entitling the Killeens to rescission of the mortgage or to any other relief.
The judge properly ruled that, on the facts found by him, the bank did not commit a deceptive act under G. L. c. 93A, § 2(a), in selling the stock. The judge did not find, as Killeen argued, that the bank obtained the mortgage by representing that the stock would not be sold. On the contrary, he found that an agent of the bank told.Killeen that the bank could give no such assurance. The judge thus was not plainly wrong in finding that the bank’s sale of the stock was not deceptive. Kileen misconstrues our role in arguing that we should reach factual conclusions in disregard of the judge’s factual findings against him.
The bank’s sale of the stock, in the erroneous belief that it had the right to sell it, does not constitute an unfair act within the meaning of G. L. c. 93A, § 2(a). Just as every lawful act is not thereby automatically free from scrutiny as to its unfairness under c. 93A (see
Schubach
v.
Household Fin. Corp.,
Analyzing the situation as a whole, we see no unfair act or practice in the bank’s sale of the stock. Killeen knew that the bank was concerned about its security. That concern was reasonable. The bank had no knowledge of any substantial assets available to Killeen other than those which the bank held as security. As he testified, however, Killeen had approximately $53,000 in cash immediately available to him on the day the bank started selling the stock, and he had had those funds available for a considerable period of time. Killeen also had available securities, other than those pledged, worth at least $10,000, and a coin collection worth about $15,000. Balancing the equities in the relationship of the parties, a major factor in determining unfairness under G. L. c. 93A, § 2, we conclude that the bank’s conduct was not unfair. We discern neither an over-zealous seller taking economic advantage nor a defenseless consumer. We need not reach the question whether for other reasons relief would not be available under § 9 of G. L. c. 93A. 8
*111 The judge was correct in ruling that the mortgage was valid. The terms of the notes authorized the bank to demand additional security if it deemed the initial security to be insufficient by reason of a decline in its market value. The judge was not wrong in ruling, or plainly wrong in finding, that the bank did not obtain the mortgage by any fraudulent, deceptive, or unfair act or practice. The mortgage was not obtained on any representation that the pledged securities would not be sold. There was no unfair or deceptive act or practice within the meaning of G. L. c. 93A, § 2 (a), in the procedure by which the mortgage was obtained. 9
We reject the Killeens’ argument that they are entitled to relief because the bank violated certain provisions of G. L. c. 140C. We assume, without deciding, that Mrs. Killeen was a "customer” entitled to relief under G. L. c. 140C. See G. L. c. 140C, § 1
(n).
One of the two statutory forms of notice required by G. L. c. 140C, § 8(b), as to a mortgage on a borrower’s principal residence, did not have the bank’s name on it. Although handwriting recorded through carbon paper onto all copies of the form, a stamp with the bank’s name on it did not. The Killeens claim that the mortgage therefore must be forfeited. This omission was insignificant and unintended. The Killeens knew who the lender was, and they did not undertake
*112
seasonably to rescind the transactions, as the bank’s notice advised them they could. Section 10(6) of G. L. c. 140C provides penalties for failure to disclose any information required under G. L. c. 140C. Here the name of the lender was disclosed, and thus relief under G. L. c. 140C, § 10(6), is not available. Because the Killeens received delivery of the disclosures required by § 8 and did not cancel the transaction within the three days following the granting of the mortgage, they were not entitled thereafter to rescind the mortgage under G. L. c. 140C, § 8. There has been compliance with the requirements of law, and the Killeens sustained no loss or disadvantage. If no statutory notice at all had been given, the result would be different. See
Shepard
v.
Finance Assocs. of Auburn, Inc.,
The only other violation of G. L. c. 140C asserted by the Killeens is based on the fact that the mortgage referred to the interest rates of the loans in terms of "the small business prime rate in effect from time to time” at the bank, increased by .75%. 10 Because the three outstanding notes had different rates of interest, each based on the small business prime rate at the time of its execution, the language in the mortgage was a reasonable explanation of Killeen’s interest obligations. There is no reasonable basis for contending that the bank was trying to change the interest rates of the outstanding notes.
*113 The judge was correct in denying relief under G. L. c. 93A and G. L. c. 140C and in entering a judgment declaring the mortgage to be valid. Quite apart from G. L. c. 93A and G. L. c. 140C, however, Killeen is entitled to damages for the wrongful sale of the stock, a question to which we now turn.
Damages
Killeen is entitled to recover the fair market value of the stock at the time of its sale by the bank.
Hall
v.
Paine,
The only question is which of the prices at which the stock sold during June 25, 1974, should be used in computing Killeen’s damages. In certain circumstances, such as in the valuation for tax purposes of stock traded on a stock exchange, the mean between the high and the low of the day’s selling prices is the appropriate measure. See, e.g., Massachusetts Inheritance and Estate Taxes Procedural Manual, § 4 (a), printed in 1 G. Newhall, Settlement of Estates 122 (4th ed. 1958, Cum. Supp. 1978); Treas. Reg. § 20.2031-2(b)(l), T.D. 7327, 1974-
We, therefore, accept Killeen’s contention that, at the least, he is entitled to the value of his stock measured by the highest price for which shares of that stock sold during June 25, 1974.
12
We reject, however, Killeen’s further contention that he is entitled to the return of an equivalent number of shares of stock in the company or that his damages should be measured by the higher value of the stock at some subsequent date. We have long rejected such claims where securities had an ascertainable market value and that market value was not affected by peculiar circumstances.
Hall
v.
Paine, supra
at 64-69, and cases cited. On the other hand, we reject the bank’s argument that Killeen is entitled only to nominal damages. The bank contends that Killeen could have mitigated his damages by purchasing replacement shares at prices the same as, or lower than, those at which the bank sold the stock. Such a rule has been applied where a stockbroker sold a customer’s securities without right and the securities thereafter declined in value. See
Dennett
v.
Wilmerding,
The wrong was committed when the bank foreclosed on all the stock at one time, by determining to sell all the stock and placing an order for its sale. On remand, a judgment shall be entered to reflect Killeen’s damages based on a valuation of the stock at $10 a share.
Interest Obligations
The bank challenges the judge’s determination to reduce Killeen’s obligations to the bank as of June 25, 1974, by the fair market value of the stock on that date. It argues that Killeen’s entire obligation to it should have continued to bear interest at the rates stated in the notes *116 until the date of judgment, and that Killeen’s claim for the wrongful sale of his stock should bear interest to the date of judgment at the lower statutory rate of 8% (see G. L. c. 231, § 6C).
The judge was correct in reducing Killeen’s obligations to the bank as of June 25,1974, by the fair market value of the stock. If Killeen had made payment to the bank on that date in a like amount, his obligations to the bank would have been reduced immediately to that extent. The bank is hardly in a position to claim that the result should be otherwise, when it foreclosed on the stock to pay itself in advance of the due dates of the notes and in violation of its contractual obligations to Killeen. 14
Conclusion
The judgment is vacated, and the case is remanded to the Superior Court for the entry of a judgment consistent with this opinion.
So ordered.
Notes
The first note was stated to be secured by slightly more than 28,500 shares of stock in the company, but no point of that difference has been made in this case. Certain life insurance policies were also pledged as *103 security. Those policies were sold by the bank at a later time. Killeen has not complained of that sale.
The judge expressed this result in different terms. He credited Killeen with (a) the proceeds of the sale of the stock received by the bank and (b) the difference between the value of the stock on June 25, 1974, and the proceeds of the sale of the stock — that is, the damages for the breach.
As to a debtor already in default, notice of acceleration is not necessary to advance the due date of an obligation; the commencement of suit itself makes an acceleration provision operative.
Quaranto
v.
Silverman,
The notes in this case permitted the bank to make the obligations due when it deemed itself insecure. They did not state that a default existed when the bank deemed itself insecure, or that in such a situation the bank had a right directly to foreclose on the stock. Cases where the agreement contained such provisions are of no assistance to the bank in this case. See, e.g.,
Universal C.I.T. Credit Corp.
v.
Shepler,
A cause of action in the case of a time instrument accrues on the
*108
day after maturity. G. L. c. 106, § 3-122(l)(a). The notes here were "payable at a definite time.” G. L. c. 106, § 3-109(l)(c). The implication of these provisions is that there is no default under a time instrument until the end of the day during which the obligation under the instrument matures, and that at least until that moment there is no right to foreclose. See
Bethlehem Acceptance Corp.
v.
Ed Newman Motor Co.,
There is a paucity of authority on the right of a creditor to foreclose without notice to, and demand on, the debtor where the creditor, feeling insecure, has accelerated the maturity of the debtor’s obligation and the debtor is not thereby or otherwise in default. In many situations, no doubt, the agreement explicitly authorizes the creditor to proceed against the collateral without notice or demand. In fact, in this case, the record contains a form of note, used by the bank in a previous loan to Killeen, which permits such action. In other cases, the agreement may explicitly require a demand after acceleration when the creditor has deemed itself insecure. See
Klingbiel
v.
Commercial Credit Corp.,
There are a number of considerations which might bear further on the availability of relief under G. L. c. 93A, § 9(1). (a) At the time of the loans, Killeen was in the business of buying and selling stock for his own gain. He had apparently used borrowed funds, in part, to purchase the stock pledged to the bank. If the proceeds of the original loans were used in Killeen’s business to purchase stock, the loan transactions might not qualify as loans "primarily for personal, family or household purposes” under G. L. c. 93A, § 9(1). See
Slaney
v.
Westwood Auto, Inc.,
The considerations expressed in note 8 above are also relevant to whether the Killeens are entitled to relief under G. L. c. 93A, § 9(1), with respect to the mortgage. Mrs. Killeen seemingly would have no claim under § 9 in any event because she was not one who purchased or leased goods, services, or property from the bank. See
Dodd
v.
Commercial Union Ins. Co.,
The Killeens’ brief refers rather nonspecifically to violations of the disclosure requirements of G. L. c. 140C, §§ 5, 7, and 10.
All subsequent sales during the period from June 25 to June 28 were at lower prices, although that circumstance is irrelevant where the crucial value is the value at the time of the foreclosure on the stock. See
Somerville Nat’l Bank
v.
Hornblower,
It is in this respect only that we disagree with the judge’s rulings on any aspect of the case.
If the stock had appreciated in value between June 25 and the dates on which it was sold, perhaps the bank would not have been entitled to profit from the appreciation.
In view of this conclusion, we need not decide whether the rates of interest set forth in the notes (reflecting Killeen’s interest obligations to the bank) should be treated as "contract rates” (see G. L. c. 231, § 6C) to be used in lieu of the statutory interest rate not only as to Killeen but also as to the bank. The parties apparently agree that the rates in the notes are "contract rates” as to Killeen. If they were "contract rates” as to the bank as well, they would reflect the rate or rates of interest on the bank’s obligations to Killeen. If the obligations of both the bank and Killeen bore the same rates of interest, it would not matter as of what date the net obligation of the parties was determined.
