As of December 31, 2016, the Company had capital commitments of approximately $1.3 million with respect to unfunded obligations in private equity funds sponsored by the Company.

As of December 31, 2016, the Company had no collateralized or uncollateralized letters of credit outstanding.

Contingencies

Many aspects of the Company's business involve substantial risks of liability. In the normal course of business, the Company has been named as defendant or co-defendant in various legal actions, including arbitrations, class actions, and other litigation, creating substantial exposure. Certain of the actual or threatened legal matters include claims for substantial compensatory and/or punitive damages or claims for indeterminate amounts of damages. These proceedings arise primarily from securities brokerage, asset management and investment banking activities. The Company is also involved, from time to time, in other reviews, investigations and proceedings (both formal and informal) by governmental and self-regulatory agencies regarding the Company's business which may result in adverse judgments, settlements, fines, penalties, injunctions or other relief. The investigations include, among other things, inquiries from the Securities and Exchange Commission (the "SEC"), the Financial Industry Regulatory Authority ("FINRA") and various state regulators.

The Company accrues for estimated loss contingencies related to legal and regulatory matters when available information indicates that it is probable a liability had been incurred and the Company can reasonably estimate the amount of that loss. In many proceedings, however, it is inherently difficult to determine whether any loss is probable or even possible or to estimate the amount of any loss. In addition, even where loss is possible or an exposure to loss exists in excess of the liability already accrued with respect to a previously recognized loss contingency, it is often not possible to reasonably estimate the size of the possible loss or range of loss or possible additional losses or range of additional losses.

For certain legal and regulatory proceedings, the Company cannot reasonably estimate such losses, particularly for proceedings that are in their early stages of development or where plaintiffs seek substantial, indeterminate or special damages. Numerous issues may need to be reviewed, analyzed or resolved, including through potentially lengthy discovery and determination of important factual matters, and by addressing novel or unsettled legal questions relevant to the proceedings in question, before a loss or range of loss or additional loss can be reasonably estimated for any proceeding. Even after lengthy review and analysis, the Company, in many legal and regulatory proceedings, may not be able to reasonably estimate possible losses or range of loss.

For certain other legal and regulatory proceedings, the Company can estimate possible losses, or range of loss in excess of amounts accrued, but does not believe, based on current knowledge and after consultation with counsel, that such losses individually, or in the aggregate, will have a material adverse effect on the Company's consolidated financial statements as a whole.

For legal and regulatory proceedings where there is at least a reasonable possibility that a loss or an additional loss may be incurred, the Company estimates a range of aggregate loss in excess of amounts accrued of $0 to $47.0 million. This estimated aggregate range is based upon currently available information for those legal proceedings in which the Company is involved, where an estimate for such losses can be made. For certain cases, the Company does not believe that an estimate can currently be made. The foregoing estimate is based on various factors, including the varying stages of the proceedings (including the fact that many are currently in preliminary stages), the numerous yet-unresolved issues in many of the proceedings and the attendant uncertainty of the various potential outcomes of such proceedings. Accordingly, the Company's estimate will change from time to time, and actual losses may be more than the current estimate.

In February 2010, Oppenheimer finalized settlements with the Regulators concluding investigations and administrative proceedings by the Regulators concerning Oppenheimer's marketing and sale of ARS. Pursuant to the settlements with the Regulators, Oppenheimer agreed to extend offers to repurchase ARS from certain of its clients subject to certain terms and conditions more fully described below. As of December 31, 2016, the Company had $5.0 million of outstanding ARS purchase commitments related to the settlements with the Regulators. In addition to the settlements with the Regulators, Oppenheimer has also reached settlements of and received adverse awards in legal proceedings with various clients where the Company is obligated to purchase ARS. Pursuant to completed Purchase Offers (as defined) under the settlements with the Regulators and client related legal settlements and awards to purchase ARS, as of December 31, 2016, the Company purchased and holds (net of redemptions) approximately $88.1 million in ARS from its clients. In addition, the Company is committed to purchase another $26.0 million in ARS from clients through 2020 under legal settlements and awards.

The Company's purchases of ARS from its clients holding ARS eligible for repurchase will, subject to the terms and conditions of the settlements with the Regulators, continue on a periodic basis. Pursuant to these terms and conditions, the Company is required to conduct a financial review every six months, until the Company has extended Purchase Offers to all Eligible Investors (as defined), to determine whether it has funds available, after giving effect to the financial and regulatory capital constraints applicable to the Company, to extend additional Purchase Offers. The financial review is based on the Company's operating results, regulatory net capital, liquidity, and other ARS purchase commitments outstanding under legal settlements and awards (described below). There are no predetermined quantitative thresholds or formulas used for determining the final agreed upon amount for the Purchase Offers. Upon completion of the financial review, the Company first meets with its primary regulator, FINRA, and then with representatives of the NYAG and other regulators to present the results of the review and to finalize the amount of the next Purchase Offer. Various offer scenarios are discussed in terms of which Eligible Investors should receive a Purchase Offer. The primary criteria to date in terms of determining which Eligible Investors should receive a Purchase Offer has been the amount of household account equity each Eligible Investor had with the Company in February 2008. Once various Purchase Offer scenarios have been discussed, the regulators, not the Company, make the final determination of which Purchase Offer scenario to implement. The terms of settlements provide that the amount of ARS to be purchased during any period shall not risk placing the Company in violation of regulatory requirements.

Eligible Investors for future buybacks continued to hold approximately $33.4 million of ARS principal value as of December 31, 2016. It is reasonably possible that some ARS Purchase Offers will need to be extended to Eligible Investors holding ARS prior to redemptions (or tender offers) by issuers of the full amount that remains outstanding. The potential additional losses that may result from entering into ARS purchase commitments with Eligible Investors for future buybacks represents the estimated difference between the principal value and the fair value. It is possible that the Company could sustain a loss of all or substantially all of the principal value of ARS still held by Eligible Investors but such an outcome is highly unlikely. The amount of potential additional losses resulting from entering into these commitments cannot be reasonably estimated due to the uncertainties surrounding the amounts and timing of future buybacks that result from the six-month financial review and the amounts, scope, and timing of future issuer redemptions and tender offers of ARS held by Eligible Investors. The range of potential additional losses related to valuation adjustments is between $0 and the amount of the estimated differential between the principal value and the fair value of ARS held by Eligible Investors for future buybacks that were not yet purchased or committed to be purchased by the Company at any point in time. The range of potential additional losses described here is not included in the estimated range of aggregate loss in excess of amounts accrued for legal and regulatory proceedings described above.

Outside of the settlements with the Regulators, the Company has also reached various legal settlements with clients and received unfavorable legal awards requiring it to purchase ARS. The terms and conditions including the ARS amounts committed to be purchased under legal settlements and awards are based on the specific facts and circumstances of each legal proceeding. In most instances, the purchase commitments are in increments and extend over a period of time. As of December 31, 2016, there were no ARS purchase commitments related to legal settlements extending past 2020.

The Company has sought, with limited success, financing from a number of sources to try to find a means for all its clients to find liquidity from their ARS holdings and will continue to do so. There can be no assurance that the Company will be successful in finding a liquidity solution for all its clients' ARS.

On January 27, 2015, the SEC approved an Offer of Settlement from Oppenheimer and issued an Order Instituting Administrative and Cease and Desist Proceedings (the "Order"). Pursuant to the Order, Oppenheimer was ordered to (i) cease and desist from committing or causing any violations of the relevant provisions of the federal securities laws; (ii) be censured; (iii) pay to the SEC $10.0 million comprised of $4.2 million in disgorgement, $753,500 in prejudgment interest and $5.1 million in civil penalties; and (iv) retain an independent consultant to review Oppenheimer's policies and procedures relating to anti-money laundering and Section 5 of the Securities Act of 1933.

Oppenheimer made a payment of $5.0 million to the SEC on February 17, 2015 and agreed to make a second payment of $5.0 million to the SEC before January 27, 2017 which payment was made to the SEC on January 26, 2017.

On the same date the Order was issued, a division of the United States Department of the Treasury ("FinCEN") issued a Civil Monetary Assessment (the "Assessment") against Oppenheimer relating to potential violations of the Bank Secrecy Act ("BSA") and the regulations promulgated thereunder related primarily to, in the Company's view, the SEC matter discussed immediately above. Pursuant to the terms of the Assessment, Oppenheimer admitted that it violated the BSA and consented to the payment of a civil money penalty, which, as a result of the payments to the SEC described above, obligates Oppenheimer to make an aggregate payment of $10.0 million to FinCEN. On February 9, 2015, Oppenheimer made a payment of $5.0 million to FinCEN and has agreed to make a second payment of $5.0 million before January 27, 2017 which payment was made to FinCEN on January 26, 2017.

Since early 2014, Oppenheimer has been responding to information requests from FINRA regarding the supervision of one of its former financial advisers who was indicted by the United States Attorney's Office for the District of New Jersey in March 2014 on allegations of insider trading. In August 2014, Oppenheimer received information requests from the SEC regarding supervision of the same financial adviser. A number of Oppenheimer employees have provided on-the-record testimony in connection with the SEC inquiry. Oppenheimer is continuing to cooperate with both the FINRA and SEC inquiries.

In September 2016, Oppenheimer received a “Wells Notice” from FINRA regarding potential violations of (i) FINRA Rule

4530 for failing to make timely filings under certain sub-paragraphs of that Rule, (ii) FINRA Rules 1122 and 2010 for failure to

timely file two U/4 amendments timely, (iii) FINRA Rules 3010 and 3110 for failing to maintain a supervisory system and

written supervisory procedures reasonably designed to prevent the foregoing and (iv) FINRA Rule 2010 and 2110 for

associated violations.

In November 2016, Oppenheimer entered into a settlement with FINRA regarding each of the issues in the preceding paragraph as well as a FINRA inquiry into the purchase of Class A, B and C mutual fund shares by not-for-profit organizations and certain qualified retirement plans pursuant to which Oppenheimer, to settle all four issues, agreed to pay a fine of $1.6 million and to pay restitution to eligible clients in an amount of approximately $1.8 million.
