delivered the opinion of the Court,
in which Chief Justice PHILLIPS, Justice HECHT, Justice ■ OWEN, Justice O’NEILL, Justice JEFFERSON, Justice SMITH, and Justice WAINWRIGHT joined.A debtor violates the Texas Penal Code if he removes, conceals, or sells secured property with intent to appropriate it.1 In this case, a jury found that Sam Martin owed $50,000 to First Valley Bank of Los Fresnos, and he admits he sold a substantial part of the collateral and kept the money for himself.
Yet Martin claims the Bank maliciously prosecuted him by complaining to the authorities, who indicted him but later dismissed the charges. A Cameron County judge and jury agreed, awarding Martin more than $18 million. The court of appeals affirmed, but reduced the damages award to $4.38 million.2
As a matter of law, we find no evidence that the Bank procured the charge on which Martin was indicted. While the Bank might have handled its collection efforts differently, there was no evidence it exceeded the parties’ loan agreements. No credit system in the world can last long if creditors are punished for lawfully demanding their money back. Accordingly, we reverse.3
In March 1996, Sam Martin renewed his loan at the Bank for the ninth time, agreeing to pay principal, of $30,323.15 plus interest, and pledging all his livestock as security. Thereafter, Martin took a ranching job in Colorado, where (as he admitted at trial), “I had an address up there, but it was a ranch house out in the middle of a ranch of about 16,000 acres up in the mountains.” When the loan came due in September 1996 and the Bank demanded payment, Martin told his son to “tell them I will be there during the Christmas holidays and renegotiate the loan with them.”
Unwilling to wait, the Bank accelerated the note without notice, as the security agreement provided it could do. When Martin returned to the area and deposited a $1,500 check in his account, the Bank *469offset it against his outstanding loan, again as the loan documents provided it could do.
Irate at the Bank’s actions, Martin informed a bank officer “I’m going to leave the bank and you will not hear from me again until that money is put back into my account.” True to his word, from that time forward Martin refused to speak with anyone at the Bank, or to pay anything to the Bank.
But he did hire an attorney in New Mexico to “advise the Bank where their cattle was.” The attorney sent a letter to the Bank identifying three ranches where 75 head were located. But the ranches were huge and the cattle wild, so only twenty could be rounded up. The Bank sold these for $200 a head and credited Martin’s note.4
Unable to contact Martin or locate the other cattle, the Bank complained to the authorities — which it had every right to do. A deputy sheriff investigated, and could not locate Martin or the cattle either. He testified that the three ranches Martin identified covered more than 250 square miles of rough country and contained skittish cattle belonging to many owners, so those belonging to a particular owner could not be identified except by scouring the whole area and corralling them all. The deputy testified that the Bank never told him that twenty cattle had been found, sold, and credited to Martin’s account.
The deputy presented the results of his investigation to the district attorney’s office. Although his report and the Bank officer’s supporting affidavit focused solely on the collateral cattle that could not be found, Martin was indicted for selling or disposing of secured property in violation of the following penal statute:
A person who is a debtor under a security agreement, and who does not have a right to sell or dispose of the secured property or is required to account to the secured party for the proceeds of a permitted sale or disposition, commits an offense if the person sells or otherwise disposes of the secured property, or does not account to the secured party for the proceeds of a sale or other disposition as required, with intent to appropriate (as defined in Chapter 31) the proceeds or value of the secured property. A person is presumed to have intended to appropriate proceeds if the person does not deliver the proceeds to the secured party or account to the secured party for the proceeds before the 11th day after the day that the secured party makes a lawful demand for the proceeds or account.5
When Martin returned to the area in March 1998, he was arrested and released on bond. The charges were dropped a few months later.6
*470Taking each element of the statute in turn, Martin admitted at trial that he:
• is a debtor on an overdue note,7 and (in his own words) “I will not pay that note”;
• signed a security agreement requiring prior notice to the Bank before selling calves, and written consent from the Bank before selling other cattle;
• sold 58 head of cattle in January 1995 without the Bank’s written consent; and
• kept most of the proceeds.8
These admissions establish all the objective elements of the crime. When the objective elements of a crime reasonably appear to have been completed, a private citizen has no duty to inquire whether the suspect has some alibi or explanation before filing charges.9 Accordingly, as a matter of law Martin cannot establish the absence of probable cause, as he must do to prove malicious prosecution.10
The court of appeals found to the contrary for three reasons. First, the court of appeals found the evidence of malicious prosecution legally sufficient because the Bank reported it could not find any of Martin’s cattle, when in fact it had found and sold twenty.11 But this statement was immaterial to the indictment that ultimately issued — Martin was indicted for the cattle he sold, not for cattle the Bank found and sold. “[A] person who knowingly provides false information to the grand jury or a law enforcement official who has the discretion to decide whether to prosecute a criminal violation cannot be said to have caused the prosecution if the information was immaterial to the decision to prosecute.” 12 There was no evidence the Bank made any false statement about Martin’s sale, the only crime for which he was indicted. Because the prosecution was only for the cattle Martin sold, any false statements regarding other cattle were immaterial to it.
Second, the court of appeals found the Bank could be hable for failing to disclose material facts, even if it made no false statements.13 We have expressly held that fair disclosure is relevant to malice and causation, “but ha[s] no bearing on probable cause.”14 Once a citizen has probable cause to report a crime, there can be no malicious prosecution, even if the subsequent report fails to fully disclose all relevant facts.15 As Martin admitted the objective elements of the crime, he could not prove the Bank lacked probable cause by pointing to omissions from its report.
Finally, the court of appeals held the Bank waived its lien on the 58 cattle Martin sold because a director of the Bank helped move them for the sale. While recognizing that a director is usually not an agent of a corporation,16 the court of appeals nevertheless held the director had apparent authority because of the Bank’s *471“ostensible acquiescence to [the director’s] involvement with Martin’s loan.”17
This is wrong on several levels. First, apparent authority must be based on the acts of the principal.18 There was no proof that the bank authorized this director to do anything on Martin’s loan; the only proof offered was Martin’s testimony that “he was, I’m sure, consulted when they.... When the loan is made, it has to go before the board of directors, unless it’s a real small loan, and they have to approve it.” Aside from the fact that this is pure speculation, it asserts no act by the Bank that clothed the individual directors with apparent authority to act on them own toward outsiders. When a corporation’s directors vote at a meeting, that does not authorize them to act unilaterally on the corporation’s behalf; indeed, the former is precisely the opposite of the latter.
Second, apparent authority is limited to the scope of responsibility that is apparently authorized.19 Requiring bank directors to approve a loan on a record vote does not authorize them to orally release the collateral or forgive the debt. If apparent authority could do that, in many cases it would be an apparent violation of federal law.20
Third, there is no evidence the director ever waived any of the Bank’s rights expressly; Martin asserts only an implied waiver. Waiver may be implied only if the surrounding facts clearly demonstrate it; there can be no waiver if the actor says and does nothing inconsistent with its rights.21 Bankers have every reason to help a debtor sell collateral at a good price, as long as the bank gets paid. Even if the actions alleged here were authorized by the Bank, they might imply approval of the sale, but give no indication whatsoever that the Bank did not care what happened to the money. As a matter of law, there is no indication in the director’s actions of an intent to waive the Bank’s security interest in the proceeds of Martin’s sale.22
Martin asserts there was no probable cause to believe his sale of the 58 head of cattle violated the Penal Code for a reason besides the alleged waiver. He maintained throughout the trial that he pledged only 75 head of cattle, and could not have intended to impair the Bank’s collateral as he had more than 100 cattle somewhere in south Texas after the sale. But every security agreement he signed (there were nine in all) stated that all his cattle were pledged as collateral:
The collateral shall consist of all the following described property and Owner’s rights, title and interest in such property whether now owned or hereafter acquired by Owner and wheresoever located:
[[Image here]]
ALL LIVESTOCK NOW OWNED OR HEREAFTER ACQUIRED BY DEBT*472OR, WHEREVER LOCATED INCLUDING BUT NOT LIMITED TO SEVENTY-FIVE (75) HEAD OF CROSSBREED CATTLE. (Emphasis in original).
Martin admitted he knew this is what the loan documents said.23
Martin claimed there was an oral agreement the loan would be secured by only 75 head of cattle, pointing for support to a notice of the security interest and a pre-loan appraisal. It is elementary that none of these could alter or amend the Bank’s security agreement. No pre-loan discussions or appraisal could survive the security agreements the parties actually signed.24 Nor could the notice to third parties amend the loan documents between the first two.25 If security documents in Texas mean what they say (and no credit system can survive if they do not), as a matter of law Martin pledged all his livestock.
To sum up, nothing the Bank reported or failed to report caused the indictment relating to Martin’s cattle sale. The documents Martin signed required him to pay the loan when it came due, and assemble the cattle at the Bank’s request if he did not;26 he makes no apology for failing to do either. As a matter of law, Martin owes the Bank, not the other way around.
For the forgoing reasons, we reverse the court of appeals’ judgment, and remand to the trial court for entry of judgment in favor of the Bank in accordance with the jury’s finding regarding Martin’s debt to the Bank.27
Justice WAINWRIGHT filed a concurring opinion.

. Because &ere was no evidence of either a false statement or a failure to disclose information that was material to Martin’s sale— the only indicted offense — we need not decide whether the Bank preserved error, if any, regarding the Court’s charge allowing liability on either ground.
. The cattle were sold to a brother of a bank director at a price Martin claims was half of what they were worth. But any claim that the Bank’s sale was not commercially reasonable, see Tex. Bus. & Com.Code § 9.610 (formerly § 9.504), was resolved against Martin by the jury’s finding that he owed the Bank the full $50,000 it claimed, a finding he does not challenge on appeal.
. Tex. Pen.Code § 32.33(e). Although the indictment alleged Martin sold or disposed of cattle in January of 1997, neither party nor the investigating officer knew of any such sale. All agreed that Martin sold 58 head of cattle in January of 1995.
. A news article (admitted at trial over the Bank’s objection) quotes prosecutors as saying they “dropped the charge only because of a technical flaw in the written indictment, but plan to reindict Martin on the same charge soon.” Martin argues the charge was dropped when information was provided indicating his cattle were somewhere in the area. In any event, the charge was never refiled.
. Q: [By defense counsel] And you admit, do you not, that that note is now long past due, by almost two years?
A: [By Martin] Yes, Sir, I do.
. While Martin's son testified that his father "renewed his note and paid some principal” with the proceeds, Martin admitted receiving more than $13,000 from the sale and paid less than $3,000 to the Bank during the period.
