This advisory describes CME Clearing’s procedures for handling the “Leap Second Event” scheduled to take place at 18:59:59 CDT (19:59:59 EDT), Tuesday, June 30, 2015. The Leap Second Event is a one-second clock adjustment that is periodically applied to Coordinated Universal Time (UTC) by the International Earth Rotation Service to keep in synch with mean solar time. See additional information at http://tycho.usno.navy.mil/leapsec.html.

CME Clearing’s system clock(s) will be synchronized with UTC during the Leap Second Event timeframe. CME Clearing applications are largely unaffected and will be available during the leap second timeframe. Firms are encouraged, however, to complete their end of day processing before 18:55:00 Central time. And there will be minor changes to the end of day timings:

· Any PCS or CGM datafiles submitted between 18:55:00 and 19:05:00 Central time will be held and will be processed at 19:05:00.

· The normal end of day 19:00:00 Central time deadline for completion of trade processing will be extended to 19:20:00. This includes the deadline for completion of futures transfers for portfolio margining between interest-rate futures and interest-rate swaps.

· The deadline for submitting PCS files for CME and CBOT products will be extended from 19:30:00 to 19:45:00 Central time. The deadline for submitting PCS files for NYMEX and COMEX is unaffected and remains at 18:00:00 Central time.

· The deadline for submitting CGM files is unaffected and remains at 20:00:00.

Additionally, the FIA Market Technology Division is working closely with exchanges, vendors, and front end trading system providers worldwide to ensure the Leap Second Event occurs and passes in a seamless manner. See additional information from the FIA.

Please expect to see periodic reminders and/or updates regarding this event. If you have any questions, please contact CME Clearing at (312) 207-2525, or ccs@cmegroup.com.

NEW: Removal of RC4 Cipher Suites

CME Group is committed to information security. To deliver the best security and customer experience, we are implementing a change to CME Group web-based applications and services:

· Certification and New Release: Saturday, May 30, 2015 at 4:00 a.m. Central Daylight Time (CDT)

· Production: Saturday, June 6, 2015 at 4:00 a.m. (CDT).

Customers following CME Group Web Browser Standards should not be impacted by this change. However, if customers connect through a proxy, they should ensure their proxy supports one or more of these CME Group supported ciphers:

· TLS_RSA_WITH_AES_256_CBC_SHA256

· TLS_RSA_WITH_AES_256_CBC_SHA

· TLS_RSA_WITH_AES_128_CBC_SHA256

· TLS_RSA_WITH_AES_128_CBC_SHA

Following the change in Certification and New Release environments on Saturday, May 30, 2015, customers are encouraged to verify connections to those environments continue to function properly.

If these ciphers are not supported by the browser or proxy, customers will not be able to access the web-based applications and services.

For information on the RC4 cipher suite vulnerability, please read the Imperva study.

New June 26 Date for Submission of Additional Client Master Data

In March of 2014, CME Clearing published Clearing Advisory 14-127, which required that firms begin submitting certain additional client master data for risk management purposes in the normal course of business and to assist with default management. For futures accounts, firms may submit this data either by including it in the Customer Gross Margining (CGM) position file or by submitting a separate Margin Accounts Master file. For swaps accounts, firms may submit this data either by including it in the LSOC Collateral Value Report (CVR) files or by submitting the separate Margin Accounts Master file.

CME Clearing is now establishing a final date by which firms must begin submitting the additional client master data: Friday, June 26, 2015. The final date should give firms plenty of time to install updated code, etc. Firms that are not yet submitting the additional data may begin doing so at any time.

May 2015 Eligible ETFs and Stocks

CME Clearing accepts a select number of shares of ETFs and stocks for customer and house segregated performance bond collateral for Base Guaranty Fund products. Both ETFs and stocks are category 4 assets and are capped in total at $1 billion per clearing member firm. Please refer to the Standard Acceptable Collateral and Resources website for further details regarding acceptable collateral, haircuts, and limits.

For ETF and stock acceptance criteria and a list of eligible ETFs and stocks, please see the Standard Acceptable Collateral and Resources website. CME Clearing utilizes a tiering methodology based on average daily volume to determine the number of eligible shares per clearing member firm.

Tiering	Average Daily Volume Over Last 30 Days	Eligible Shares Per CMF
Tier 1	Greater than 10,000,000	1,000,000
Tier 2	5,000,001 - 10,000,000	500,000
Tier 3	2,500,001 - 5,000,000	250,000
Tier 4	1,000,001 - 2,500,000	100,000
Tier 5	500,000 - 1,000,000	50,000
Not eligible	Less than 500,000	None

CME Clearing utilizes the Depository Trust & Clearing Corporation (DTCC) as the custodian for the ETF and Stock Programs. In order to participate in the programs, clearing members must have an account at DTCC. For those firms familiar with the DTCC system, the CME’s account has “Repo” status.

Clearing members with an account at DTCC can originate free pledges of securities to the CME account or request the release of pledged securities from the account at the CME. CME staff has direct access to DTCC’s system to view clearing member pledges and approve release requests. Release transactions are not finalized until CME has approved the transactions. Clearing members have the opportunity to pledge securities in the morning to facilitate the release of a.m. cash calls at the intra-day performance bond cycle, or to request the release of pledged securities. The deadline for morning transactions is 10:30 a.m. CST. Clearing members have an additional opportunity to pledge securities in anticipation of increases in their overnight performance bond requirements until approximately 1:30 p.m. CST.

If you need further information about the ETF and Stock Programs, please contact the Financial Unit at (312) 207-2594 or the Risk Management Group at (312) 648-3888.

Monthly-to-Daily Conversion for Power Contracts begins on May 29, 2015

Beginning with the June 2015 contract month and pending regulatory approvals, we are introducing an important enhancement in the way that the majority of monthly NYMEX power contracts are processed at maturity. Please see Special Executive Report 7253RR.

Currently, the last day of trading for these monthly cash-settled contracts is the last business day of the contract month. With this change, the monthly contracts will terminate trading prior to the start of the contract month and positions in the monthly contracts will be transformed automatically into strips of positions in the corresponding daily contracts, thereby allowing individual daily positions to be managed separately.

For questions or further information, please contact CME Clearing Services (CCS) at 312-207-2525 or ccs@cmegroup.com.
