II. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

In its filing with the Commission, the Exchange included statements concerning the purpose of and basis for the proposed rule change and discussed any comments it received on the proposed rule change. The text of these statements may be examined at the places specified in Item IV below. The Exchange has prepared summaries, set forth in sections A, B, and C below, of the most significant aspects of such statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

1. Purpose

The Exchange proposes to amend the Market Maker Sliding Scale (defined ( printed page 13158) below) contained in its Fee Schedule to increase certain “taker” fees for certain tiers assessed to MIAX Options Market Makers,^[3] as described below.

Section (1)(a)(i) of the Fee Schedule sets forth the Exchange's Market Maker Sliding Scale for Market Maker Transaction Fees (the “Sliding Scale”). The Sliding Scale assesses a per contract transaction fee on a Market Maker for the execution of simple orders and quotes (collectively, “simple orders”) and complex orders and quotes (collectively, “complex orders”). The amount of the transaction fee is based on the Market Maker's percentage of total national market maker volume in all options classes that trade on the Exchange during a particular calendar month, and the Exchange aggregates the volume executed by Market Makers in both simple orders and complex orders for purposes of determining the applicable tier and corresponding per contract transaction fee amount.^[4] The Sliding Scale applies to all MIAX Options Market Makers for transactions in all products (except for mini-options, for which there are separate product fees), with fees established for option classes in the Penny Pilot Program ^[5] (“penny option classes”) and separate fees for non-penny option classes, and further based on whether the Market Maker is acting as a “maker” or a “taker” ^[6] in simple orders. Market Makers that place resting liquidity, i.e., quotes or orders on the MIAX Options System,^[7] are assessed the “maker” fee. Market Makers that execute against (remove) resting liquidity are assessed a higher “taker” fee. This is distinguished from traditional “maker-taker” models where “makers” typically receive a rebate and “takers” are assessed a fee; the Exchange instead assesses lower transaction fees to “makers” as compared to “takers,” similar to the manner implemented at other exchanges.^[8]

Further, the Exchange provides discounted transaction fees for Members ^[9] and their qualified Affiliates ^[10] that achieve certain volume thresholds through the submission of Priority Customer ^[11] orders under the Exchange's Priority Customer Rebate Program (“PCRP”),^[12] which is set forth on two tables: One setting forth the transaction fees applicable to Members and their Affiliates that are in PCRP Volume Tier 3 or higher; and the other setting forth the transaction fees applicable to Members and their Affiliates that are not in PCRP Volume Tier 3 or higher. The Sliding Scale also includes maker and taker fees in both tables in each tier for simple orders in penny option classes and non-penny option classes.

The current Sliding Scale tables are as follows:

The Exchange proposes to increase the taker fees as set forth in both tables below:

The Exchange has determined to substantially reduce the magnitude of volume discounts that Market Makers achieve in Tiers 3, 4, and 5, as a taker for Members who are in the Priority Customer Rebate Program Volume Tier 3 or Higher and for Members who are not in the Priority Customer Rebate Program Volume Tier 3 or Higher. This significant, volume-based discount was designed to incentivize Market Makers to act as a taker on the Exchange.^[13] For business and competitive reasons, the Exchange now believes it is appropriate to reduce the magnitude of discounts. The Exchange is not eliminating the discounts entirely, but narrowing the ranges between the highest fee (assessed for Tier 1) and fees assessed in Tiers 3, 4, and 5) in each of the two tables. The proposed Market Maker taker fees are ( printed page 13160) generally in line with the Market Maker taker fees charged by other exchanges for executing simple orders at similar volume levels, including Exchanges that don't offer a volume discount for market maker taker volume.^[14]

The proposed rule change is scheduled to become operative March 1, 2017.

2. Statutory Basis

The Exchange believes that its proposed rule change is consistent with Section 6(b) of the Act ^[15] in general, and furthers the objectives of Sections 6(b)(4) of the Act,^[16] in that it is an equitable allocation of reasonable fees and other charges among Exchange Members and other persons using its facilities, and Section 6(b)(5) of the Act,^[17] in that it is designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, to foster cooperation and coordination with persons engaged in facilitating transactions in securities, to remove impediments to and perfect the mechanisms of a free and open market and a national market system and, in general, to protect investors and the public interest.

The proposed taker fee increase for the various tiers is equitable and not unfairly discriminatory because all similarly situated Market Makers are subject to the same fees and access to the Exchange is offered on terms that are not unfairly discriminatory. The Exchange initially set its taker fees at the various volume levels based upon business determinations and an analysis of current taker fees and volume levels at other exchanges. When the Exchange initially adopted taker fees,^[18] it set its higher tier taker fees much lower than other exchanges in order to encourage its Market Makers to reach for higher volume levels in order to achieve greater discounts. For competitive and business reasons, the Exchange believes that it no longer needs to offer such deep discounts in the higher tiers and desires to narrow the range between the lower and higher tiers with respect to the taker fees. The Exchange also believes that it is appropriate to increase taker fees to be more in line with competing exchanges. The Exchange notes that the increased taker fees are comparable to those assessed by other exchanges and that even with the increase, the Exchange's taker fees are still less than those assessed by such exchanges.^[19]

The Exchange's proposal to assess a higher fee to Market Makers that take liquidity in penny option and non-penny option classes is also reasonable, equitable and not unfairly discriminatory under the Act. While distinguished from the traditional “maker-taker” fee model under which an exchange pays a per-contract rebate to their members to encourage them to place resting liquidity by providing quotes and orders (“maker”) on their trading systems and assessing a fee that executes against a resting order (“taker”), the Exchange assesses a reduced fee for “makers” as compared to “takers” rather than giving the “maker” a rebate.

The Exchange believes that the maker-taker pricing model is an important competitive tool for exchanges and directly or indirectly can provide better prices for investors. Such pricing models may narrow the MIAX Options Bid and Offer (“MBBO”) because the reduced fee for “makers” effectively subsidizes, and thus encourages, the posting of liquidity, while the assessment of lower fees in higher tiers to “takers” encourages Market Makers to provide order flow. The Exchange believes that this pricing model provides Market Makers with greater incentive to either match or improve upon the best price displayed on MIAX Options, all to the benefit of investors and the public in the form of improved execution prices.

Further, the Exchange's assessment of a higher fee to Market Makers who remove liquidity is reasonable, equitable and not unfairly discriminatory and follows a similar line of reasoning. It is common practice among options exchanges to differentiate between fees for adding liquidity and fees for removing liquidity, and such differentiation has been accepted as not unfairly discriminatory under the Act.^[20] The Exchange believes that the differentiation in pricing between “makers” and “takers” is appropriate, because “takers” remove liquidity and benefit disproportionately from their executions as compared to “makers,” without assuming the obligations that “makers” assume in making continuous, two-sided markets, and without engaging in competitive price discovery and improvement in the same manner as “makers.” Liquidity removers benefit from the price and size discovery function that liquidity providers have performed in posting their quotations and orders, and when executing against resting liquidity, a “taker” is not taking the risk of an order or quote sitting unexecuted on the Book. The Exchange believes for these reasons that assessing a higher “taker” fee for the various tiers for simple orders is equitable, reasonable and not unfairly discriminatory, and thus consistent with the Act.

B. Self-Regulatory Organization's Statement on Burden on Competition

The Exchange does not believe that the proposed rule change will result in any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act. The proposed fee structure is intended to promote narrower spreads and encourage the posting of liquidity (instead of taking liquidity), and thus should promote better prices. The proposed rule change should enable the Exchange to attract, and compete for, order flow with other exchanges and the higher fees for removing liquidity will encourage Market Makers to submit order flow that adds liquidity, not removes it.

The Exchange notes that it operates in a highly competitive market in which market participants can readily favor competing venues if they deem fee levels at a particular venue to be excessive. In such an environment, the Exchange must continually adjust its fees to remain competitive with other exchanges and to attract order flow. The Exchange believes that the proposed rule changes reflect this competitive environment because they modify the Exchange's fees in a manner that encourages market participants to provide liquidity and to send order flow to the Exchange rather than remove liquidity from the market place.
